THE
COMPANY
Aehr
Test was incorporated in the state of California on May 25, 1977.
We develop, manufacture and sell systems which are designed to
reduce the cost of testing and to perform reliability screening, or
burn-in, of complex logic devices, memory ICs, sensors and optical
devices. These systems can be used to simultaneously perform
parallel testing and burn-in of packaged integrated circuits, or
ICs, singulated bare die or ICs still in wafer form. Increased
quality and reliability needs of the Automotive, Mobility and flash
memory integrated circuit markets are driving additional testing
requirements, capacity needs and opportunities for Aehr Test
products in package and wafer level testing. Leveraging its
expertise as a long-time leading provider of burn-in equipment,
with over 2,500 systems installed worldwide, the Company has
developed and introduced several innovative product families,
including the ABTS
TM
and
FOX
TM
systems, the
WaferPak
TM
cartridge and the DiePak
®
carrier. The
latest ABTS family of packaged part burn-in and test systems can
perform test during burn-in of complex devices, such as digital
signal processors, microprocessors, microcontrollers and
systems-on-a-chip, and offers individual temperature control for
high-power advanced logic devices. The FOX systems are full wafer
contact parallel test and burn-in systems designed to make contact
with all pads of a wafer simultaneously, thus enabling full wafer
parallel test and burn-in. They are also used for parallel test and
burn-in singulated die or very small multi-IC modules. The WaferPak
cartridge includes a full-wafer probe card for use in testing
wafers in FOX systems. The DiePak carrier is a reusable, temporary
package that enables IC manufacturers to perform cost-effective
test and burn-in of singulated bare die or very small multi-IC
modules.
INDUSTRY
BACKGROUND
Semiconductor
manufacturing is a complex, multi-step process, and defects or
weaknesses that may result in the failure of an integrated circuit,
or IC, may be introduced at any process step. Failures may occur
immediately or at any time during the operating life of an IC,
sometimes after several months of normal use. Semiconductor
manufacturers rely on testing and reliability screening to identify
and eliminate defects that occur during the manufacturing
process.
Testing
and reliability screening involve multiple steps. The first set of
tests is typically performed by IC manufacturers before the
processed semiconductor wafer is cut into individual die, in order
to avoid the cost of packaging defective die into their packages.
This “wafer probe” testing can be performed on one or
many die at a time, including testing the entire wafer at once.
After the die are packaged and before they undergo reliability
screening, a short test is typically performed to detect packaging
defects. Most leading-edge microprocessors, microcontrollers,
digital signal processors, memory ICs, sensors and optical devices
(such as vertical-cavity surface-emitting lasers, or VCSELs) then
undergo an extensive reliability screening and stress testing
procedure known as “burn-in” or “cycling,”
depending on the application. The burn-in process screens for early
failures by operating the IC at elevated voltages and temperatures,
up to 150 degrees Celsius (302 degrees Fahrenheit), for periods
typically ranging from 2 to 48 hours. A typical burn-in system can
process thousands of ICs simultaneously. After burn-in, the ICs
undergo a final test process using automatic test equipment, or
testers. The cycling process screens flash memory devices for
failure to meet write/erase cycling endurance
requirements.
PRODUCTS
The
Company manufactures and markets full wafer contact test systems,
test during burn-in systems, test fixtures and related
accessories.
4
All
of the Company’s systems are modular, allowing them to be
configured with optional features to meet customer requirements.
Systems can be configured for use in production applications, where
capacity, throughput and price are most important, or for
reliability engineering and quality assurance applications, where
performance and flexibility, such as extended temperature ranges,
are essential.
FULL WAFER CONTACT SYSTEMS
The
FOX-XP test and burn-in system, introduced in July 2016, is
designed for devices in wafer, singulated die, and module form that
require test and burn-in times typically measured in hours. The
FOX-XP system can test and burn in up to 18 wafers at a time. For
high reliability applications, such as automotive, mobile devices,
sensors, and SSDs, the FOX-XP system is a cost-effective solution
for producing tested and burned-in die for use in multi-chip
packages. Using Known-Good Die, or KGD, which are fully burned-in
and tested die, in multi-chip packages helps assure the reliability
of the final product and lowers costs by increasing the yield of
high-cost multi-chip packages. Wafer-level burn-in and test enables
lower cost production of KGD for multi-chip modules, 3-D stacked
packages and systems-in-a-package. The FOX-XP system has been
extended for burn-in and test of small multi-die modules by using
DiePak carriers. The DiePak carrier with its multi-module sockets
and high wattage dissipation capabilities has a capacity of
hundreds of modules, much higher than the capacity of a traditional
burn-in system with traditional single-die sockets and heat sinks.
This capability was introduced in March 2017.
The
FOX-15 full wafer parallel test system, the predecessor to the
FOX-XP system, was introduced in October 2007 and was designed for
full-wafer test and burn-in. The FOX-15 system is nearing the end
of its lifecycle and limited shipments are expected in the
future.
The
FOX-1P full wafer parallel test system, introduced in October 2014,
is designed for massively parallel test of devices at wafer level.
The FOX-1P system is designed to make electrical contact to and
test all of the die on a wafer in a single touchdown. The FOX-1P
test head and WaferPak contactor are compatible with
industry-standard 300 mm wafer probers which provide the wafer
handling and alignment automation for the FOX-1P system. The FOX-1P
pattern generator is designed to functionally test
industry-standard memory devices such as flash and DRAMs, plus it
is optimized to test memory or logic ICs that incorporate design
for testability, or DFT, and built-in self-test, or BIST. The
FOX-1P universal per-pin architecture to provide per-pin
electronics and per-device power supplies is tailored to full-wafer
functional test. The Company believes that the FOX-1P system can
significantly reduce the cost of testing IC wafers. The
Company’s FOX-1P system was partially funded through a
development agreement with a leading semiconductor manufacturer.
The Company received the first production order of this new system
and shipped the first system in July 2016.
One
of the key components of the FOX systems is the patented WaferPak
cartridge system. The WaferPak cartridge contains a full-wafer
single-touchdown probe card which is easily removable from the
system. Traditional probe cards contact only a portion of the
wafer, requiring multiple touchdowns to test the entire wafer. The
unique design is intended to accommodate a wide range of contactor
technologies so that the contactor technology can evolve along with
the changing requirements of the customer’s wafers. The
WaferPak cartridges are custom designed for each device type, each
of which has a typical lifetime of 2 to 7 years, depending on the
device life cycle. Therefore, multiple sets of WaferPak cartridges
could be purchased over the life of a FOX system.
A
key new component of the FOX-XP systems is the patent-pending
DiePak carrier system. The DiePak carrier contains many
multi-module sockets with very fine-pitch probes which are easily
removable from the system. Traditional sockets contact only a
single device, requiring multiple large numbers of sockets and
burn-in boards to test a production lot of devices. The unique
design is intended to accommodate a wide range of socket sizes and
densities so that the DiePak carrier technology can evolve along
with the changing requirements of the customer’s devices. The
DiePak carriers are custom designed for each device type, each of
which has a typical lifetime of 2 to 7 years, depending on the
device life cycle. Therefore, multiple sets of DiePak carriers
could be purchased over the life of a FOX-XP system.
Another
key component of our FOX-XP and FOX-15 test cell is the WaferPak
Aligner. The WaferPak Aligner performs automatic alignment of the
customer’s wafer to the WaferPak cartridge so that the wafer
can be tested and burned-in by the FOX-XP and FOX-15 systems.
Typically one WaferPak Aligner can support several FOX-XP or FOX-15
systems.
Similar
to the WaferPak Aligner for WaferPak cartridges, Aehr Test offers a
DiePak Loader for DiePak carriers. The DiePak Loader performs
automatic loading of the customer’s modules to the DiePak
carrier so that the modules can be tested and burned-in by the
FOX-XP system. Typically one DiePak Loader can support several
FOX-XP systems.
5
The
full wafer contact systems product category accounted for
approximately 44%, 51% and 60% of the Company’s net sales in
fiscal 2018, 2017 and 2016, respectively.
SYSTEMS FOR PACKAGED PARTS
Test
during burn-in, or TDBI, systems consist of several subsystems:
pattern generation and test electronics, control software, network
interface and environmental chamber. The test pattern generator
allows duplication of most of the functional tests performed by a
traditional tester. Pin electronics at each burn-in board, or BIB,
position are designed to provide accurate signals to the ICs being
tested and detect whether a device is failing the
test.
Devices
being tested are placed on BIBs and loaded into environmental
chambers which typically operate at temperatures from 25 degrees
Celsius (77 degrees Fahrenheit) up to 150 degrees Celsius (302
degrees Fahrenheit) (optional chambers can produce temperatures as
low as -55 degrees Celsius (-67 degrees Fahrenheit)). A single BIB
can hold up to several hundred ICs, and a production chamber holds
up to 72 BIBs, resulting in thousands of memory or logic devices
being tested in a single system.
The
Advanced Burn-in and Test System, or ABTS, was introduced in fiscal
2008. The ABTS family of products is based on a hardware and
software architecture that is intended to address not only
today’s devices, but also future devices for many years to
come. The ABTS system can test and burn-in both high-power logic
and low-power ICs. It can be configured to provide individual
device temperature control for devices up to 70W or more and with
up to 320 I/O channels.
The
MAX system family, the predecessor to the ABTS family, was designed
for monitored burn-in of memory and logic devices. The MAX system
is nearing the end of its lifecycle and limited shipments are
expected in the future.
This
packaged part systems product category accounted for approximately
56%, 49% and 40% of the Company’s net sales in fiscal 2018,
2017 and 2016, respectively.
TEST FIXTURES
The
Company sells, and licenses others to manufacture and sell,
custom-designed test fixtures for its systems. The test fixtures
include BIBs for the ABTS parallel test and burn-in system and for
the MAX monitored burn-in system. These test fixtures hold the
devices undergoing test or burn-in and electrically connect the
devices under test to the system electronics. The capacity of each
test fixture depends on the type of device being tested or
burned-in, ranging from several hundred in memory production to as
few as eight for high pin-count complex Application Specific
Integrated Circuits, or ASICs, or microprocessor devices. Test
fixtures are sold both with new Aehr Test systems and for use with
the Company’s installed base of systems. Test fixtures are
also available from third-party suppliers.
The
Company has received patents or applied for patents on certain
features of the FOX, ABTS and MAX4 test fixtures. The Company has
licensed or authorized several other companies to provide MAX4 BIBs
from which the Company receives royalties. Royalties and revenue
for the test fixtures product category accounted for less than 1%
of net sales in fiscal 2018, 2017 and 2016.
CUSTOMERS
The
Company markets and sells its products throughout the world to
semiconductor manufacturers, semiconductor contract assemblers,
electronics manufacturers and burn-in and test service
companies.
Sales
to the Company’s five largest customers accounted for
approximately 86%, 93%, and 94% of its net sales in fiscal 2018,
2017 and 2016, respectively. During fiscal 2018, Texas Instruments
Incorporated, or Texas Instruments, STMicroelectronics, Inc., and
Astronics Test Systems, Inc., accounted for approximately 34%, 26%
and 13%, respectively, of the Company’s net sales. During
fiscal 2017, Texas Instruments Incorporated, or Texas Instruments,
STMicroelectronics, Inc., Intel Corporation and Cypress
Semiconductor, accounted for approximately 45%, 19%, 17% and 10%,
respectively, of the Company’s net sales. During fiscal 2016,
Apple Inc. and Texas Instruments accounted for approximately 47%
and 32%, respectively, of the Company’s net sales. No other
customers accounted for more than 10% of the Company’s net
sales for any of these periods. The Company expects that sales of
its products to a limited number of customers will continue to
account for a high percentage of net sales for the foreseeable
future. In addition, sales to particular customers may fluctuate
significantly from quarter to quarter. Such fluctuations may result
in changes in utilization of the Company’s facilities and
resources. The loss of or reduction or delay in orders from a
significant customer or a delay in collecting or failure to collect
accounts receivable from a significant customer could materially
and adversely affect the Company’s business, financial
condition and operating results.
6
MARKETING,
SALES AND CUSTOMER SUPPORT
The
Company has sales and service operations in the United States,
Japan, Germany and Taiwan, dedicated service resources in China,
South Korea, and the Philippines, and has established a network of
distributors and sales representatives in certain key parts of the
world. See “REVENUE RECOGNITION” in Item 7 under
“Management’s Discussion and Analysis of Financial
Condition and Results of Operations” for a further discussion
of the Company’s relationship with distributors, and its
effects on revenue recognition.
The
Company’s customer service and support program includes
system installation, system repair, applications engineering
support, spare parts inventories, customer training and
documentation. The Company has applications engineering and field
service personnel located near and sometimes co-located at our
customers and includes resources at the corporate headquarters in
Fremont, California, at customer locations in Texas, at the
Company’s subsidiaries in Japan and Germany, at its branch
office in Taiwan, and also through 3
rd
party agreements in
China, South Korea, and the Philippines. The Company’s
distributors provide applications and field service support in
other parts of the world. The Company customarily provides a
warranty on its products. The Company offers service contracts on
its systems directly and through its subsidiaries, distributors and
representatives. The Company maintains customer support personnel
in the Philippines, China and South Korea. The Company believes
that maintaining a close relationship with customers and providing
them with ongoing engineering support improves customer
satisfaction and will provide the Company with a competitive
advantage in selling its products to the Company’s
customers.
BACKLOG
At
May 31, 2018, the Company’s backlog was $8.4 million compared
with $12.7 million at May 31, 2017. The Company’s backlog
consists of product orders for which confirmed purchase orders have
been received and which are scheduled for shipment within 12
months. Due to the possibility of customer changes in delivery
schedules or cancellations and potential delays in product
shipments or development projects, the Company’s backlog as
of a particular date may not be indicative of net sales for any
succeeding period.
RESEARCH
AND PRODUCT DEVELOPMENT
The
Company historically has devoted a significant portion of its
financial resources to research and development programs and
expects to continue to allocate significant resources to these
efforts. Certain research and development expenditures related to
non-recurring engineering milestones have been transferred to cost
of goods sold, reducing research and development expenses. The
Company’s research and development expenses during fiscal
2018, 2017 and 2016 were $4.2 million, $4.7 million and $4.3
million, respectively.
The
Company conducts ongoing research and development to design new
products and to support and enhance existing product lines.
Building upon the expertise gained in the development of its
existing products, the Company has developed the FOX family of
systems for performing test and burn-in of entire processed wafers,
rather than individual die or packaged parts. The Company has
extended the FOX-XP product to also perform test and burn-in of
devices in singulated die and module form. The Company is
developing enhancements to the ABTS and FOX families of products,
intended to improve the capability and performance for testing and
burn-in of future generation ICs and provide the flexibility in a
wide variety of applications.
MANUFACTURING
The
Company assembles its products from components and parts
manufactured by others, including environmental chambers, power
supplies, metal fabrications, printed circuit assemblies, ICs,
burn-in sockets, high-density interconnects, wafer contactors and
interconnect substrates. Final assembly and testing are performed
within the Company’s facilities. The Company’s strategy
is to use in-house manufacturing only when necessary to protect a
proprietary process or when a significant improvement in quality,
cost or lead time can be achieved and relies on subcontractors to
manufacture many of the components and subassemblies used in its
products. The Company’s principal manufacturing facility is
located in Fremont, California. The Company’s facility in
Utting, Germany provides limited manufacturing and product
customization.
COMPETITION
The
semiconductor equipment industry is intensely competitive.
Significant competitive factors in the semiconductor equipment
market include price, technical capabilities, quality, flexibility,
automation, cost of ownership, reliability, throughput, product
availability and customer service. In each of the markets it
serves, the Company faces competition from established competitors
and potential new entrants, many of which have greater financial,
engineering, manufacturing and marketing resources than the
Company.
7
The
Company’s FOX full wafer contact systems face competition
from larger systems manufacturers that have significant
technological know-how and manufacturing capability. Competing
suppliers of full wafer contact systems include Advantest
Corporation, Chroma ATE Inc., Teradyne Inc., Micronics Japan Co.,
Ltd., and Tokyo Electron Limited.
The
Company’s ABTS TDBI systems face increasingly severe
competition, especially from several regional, low-cost
manufacturers and from systems manufacturers that offer higher
power dissipation per device under test. Some users of such
systems, such as independent test labs, build their own burn-in
systems, while others, particularly large IC manufacturers in Asia,
acquire burn-in systems from captive or affiliated suppliers. The
market for burn-in systems is highly fragmented, with many domestic
and international suppliers. Competing suppliers of burn-in and
functional test systems that compete with ABTS systems include
Dong-Il Corporation, Micro Control Company, Incal Technology and
Advantest Corporation.
The
Company’s WaferPak products are facing and are expected to
face increasing competition. Several companies have developed or
are developing full-wafer and single-touchdown probe cards. As the
full-wafer test market develops, the Company expects that other
competitors will emerge. The primary competitive factors in this
market are cost, performance, reliability and assured supply.
Competing suppliers of full-wafer probe cards include FormFactor,
Inc., Japan Electronic Materials Corporation and Micronics Japan
Co., Ltd.
The
Company’s test fixture products face numerous regional
competitors. There are limited barriers to entry into the BIB
market, and as a result, many companies design and manufacture
BIBs, including BIBs for use with the Company’s ABTS and MAX
systems. The Company has granted royalty-bearing licenses to
several companies to make BIBs for use with the Company’s
MAX4 systems and the Company may grant additional licenses as well.
Sales of MAX4 BIBs by licensees result in royalties to the
Company.
The
Company expects that its DiePak products for burning-in and testing
multiple singulated die and small modules will face significant
competition. The Company believes that several companies have
developed or are developing products which are intended to enable
test and burn-in of multiple bare die, and small modules. The
Company expects that other competitors will emerge. The Company
expects that the primary competitive factors in this market will be
cost, performance, reliability and assured supply. Suppliers with
products that compete with our single die DiePak products include
Chroma ATE Inc.
The
Company expects its competitors to continue to improve the
performance of their current products and to introduce new products
with improved price and performance characteristics. New product
introductions by the Company’s competitors or by new market
entrants could cause a decline in sales or loss of market
acceptance of the Company’s products. The Company has
observed price competition in the systems market, particularly with
respect to its less advanced products. Increased competitive
pressure could also lead to intensified price-based competition,
resulting in lower prices which could adversely affect the
Company’s operating margins and results. The Company believes
that to remain competitive it must invest significant financial
resources in new product development and expand its customer
service and support worldwide. There can be no assurance that the
Company will be able to compete successfully in the
future.
PROPRIETARY
RIGHTS
The
Company relies primarily on the technical and creative ability of
its personnel, its proprietary software, and trade secrets and
copyright protection, rather than on patents, to maintain its
competitive position. The Company’s proprietary software is
copyrighted and licensed to the Company’s customers. At May
31, 2018, the Company held fifty issued United States patents with
expiration date ranges from 2018 to 2029 and had several additional
United States patent applications and foreign patent applications
pending.
The
Company’s ability to compete successfully is dependent in
part upon its ability to protect its proprietary technology and
information. Although the Company attempts to protect its
proprietary technology through patents, copyrights, trade secrets
and other measures, there can be no assurance that these measures
will be adequate or that competitors will not be able to develop
similar technology independently. Further, there can be no
assurance that claims allowed on any patent issued to the Company
will be sufficiently broad to protect the Company’s
technology, that any patent will be issued to the Company from any
pending application or that foreign intellectual property laws will
protect the Company’s intellectual property. Litigation may
be necessary to enforce or determine the validity and scope of the
Company’s proprietary rights, and there can be no assurance
that the Company’s intellectual property rights, if
challenged, will be upheld as valid. Any such litigation could
result in substantial costs and diversion of resources and could
have a material adverse effect on the Company’s business,
financial condition and operating results, regardless of the
outcome of the litigation. In addition, there can be no assurance
that any of the patents issued to the Company will not be
challenged, invalidated or circumvented or that the rights granted
thereunder will provide competitive advantages
8
to the
Company. Also, there can be no assurance that the Company will have
the financial resources to defend its patents from infringement or
claims of invalidity.
There
are currently no pending claims against the Company regarding
infringement of any patents or other intellectual property rights
of others. However, the Company may, from time to time, receive
communications from third parties asserting intellectual property
claims against the Company. Such claims could include assertions
that the Company’s products infringe, or may infringe, the
proprietary rights of third parties, requests for indemnification
against such infringement or suggest the Company may be interested
in acquiring a license from such third parties. There can be no
assurance that any such claim made in the future will not result in
litigation, which could involve significant expense to the Company,
and, if the Company is required or deems it appropriate to obtain a
license relating to one or more products or technologies, there can
be no assurance that the Company would be able to do so on
commercially reasonable terms, or at all.
EMPLOYEES
As
of May 31, 2018, the Company, including its two foreign
subsidiaries and one branch office, employed 86 persons
collectively, on a full-time basis, of whom 21 were engaged in
research, development and related engineering, 27 were engaged in
manufacturing, 25 were engaged in marketing, sales and customer
support and 13 were engaged in general administration and finance
functions. In addition, the Company from time to time employs a
number of contractors and part-time employees, particularly to
perform customer support and manufacturing. The Company’s
success is in part dependent on its ability to attract and retain
highly skilled workers, who are in high demand. None of the
Company’s employees are represented by a union and the
Company has never experienced a work stoppage. The Company’s
management considers its relations with its employees to be
good.

You should carefully consider the
risks described below. These risks are not the only risks that we
may face. Additional risks and uncertainties that we are unaware
of, or that we currently deem immaterial, also may become important
factors that affect us. If any of the following risks occur, our
business, financial condition or results of operations could be
materially and adversely affected which could cause our actual
operating results to differ materially from those indicated or
suggested by forward-looking statements made in this Annual Report
on Form 10-K or presented elsewhere by management from time to
time.
9
We generate a large portion of our sales from a small number of
customers. If we were to lose one or more of our large customers,
operating results could suffer dramatically.
The semiconductor manufacturing
industry is highly concentrated, with a relatively small number of
large semiconductor manufacturers and contract assemblers
accounting for a substantial portion of the purchases of
semiconductor equipment. Sales to our five largest customers
accounted for approximately 86%, 93%, and 94% of our net sales in
fiscal 2018, 2017 and 2016, respectively. During fiscal 2018, Texas
Instruments, STMicroelectronics, Inc., and Astronics Test Systems,
Inc., accounted for approximately 34%, 26% and 13%, respectively,
of the Company’s net sales. During fiscal 2017, Texas
Instruments, STMicroelectronics, Inc., Intel, and Cypress
Semiconductor, accounted for approximately 45%, 19%, 17% and 10%,
respectively, of the Company’s net sales. During fiscal 2016,
Apple and Texas Instruments accounted for approximately 47% and
32%, respectively, of our net sales. No other customers accounted
for more than 10% of our net sales for any of these
periods.
We
expect that sales of our products to a limited number of customers
will continue to account for a high percentage of net sales for the
foreseeable future. In addition, sales to particular customers may
fluctuate significantly from quarter to quarter. The loss of,
reduction or delay in an order, or orders from a significant
customer, or a delay in collecting or failure to collect accounts
receivable from a significant customer could adversely affect our
business, financial condition and operating results.
The semiconductor equipment industry is intensely competitive. In
each of the markets we serve, we face competition from established
competitors and potential new entrants, many of which have greater
financial, engineering, manufacturing and marketing resources than
us.
Our
FOX wafer level and singulated die/module test and burn in systems
face competition from larger systems manufacturers that have
significant technological know-how and manufacturing capability.
Our ABTS Test During Burn-in (TDBI) systems have faced and are
expected to continue to face increasingly severe competition,
especially from several regional, low-cost manufacturers and from
systems manufacturers that offer higher power dissipation per
device under test. Some users of such systems, such as independent
test labs, build their own burn-in systems, while others,
particularly large IC manufacturers in Asia, acquire burn-in
systems from captive or affiliated suppliers. Our WaferPak products
are facing and are expected to face increasing competition. Several
companies have developed or are developing full-wafer and
single-touchdown probe cards.
We
expect our competitors to continue to improve the performance of
their current products and to introduce new products with improved
price and performance characteristics. New product introductions by
our competitors or by new market entrants could cause a decline in
sales or loss of market acceptance of our products. We have
observed price competition in the systems market, particularly with
respect to its less advanced products. Increased competitive
pressure could also lead to intensified price-based competition,
resulting in lower prices which could adversely affect our
operating margins and results. We believe that to remain
competitive we must invest significant financial resources in new
product development and expand our customer service and support
worldwide. There can be no assurance that we will be able to
compete successfully in the future.
We rely on increasing market acceptance for our FOX system, and we
may not be successful in attracting new customers or maintaining
our existing customers.
A
principal element of our business strategy is to increase our
presence in the test equipment market through system sales in our
FOX wafer-level and singulated die/module test and burn-in product
family. The market for the FOX systems is in the early stages of
development. Market acceptance of the FOX system is subject to a
number of risks. Before a customer will incorporate the FOX system
into a production line, lengthy qualification and correlation tests
must be performed. We anticipate that potential customers may be
reluctant to change their procedures in order to transfer burn-in
and test functions to the FOX system. Initial purchases are
expected to be limited to systems used for these qualifications and
for engineering studies. Market acceptance of the FOX system also
may be affected by a reluctance of IC manufacturers to rely on
relatively small suppliers such as us. As is common with new
complex products incorporating leading-edge technologies, we may
encounter reliability, design and manufacturing issues as we begin
volume production and initial installations of FOX systems at
customer sites. The failure of the FOX system to achieve increased
market acceptance would have a material adverse effect on our
future operating results, long-term prospects and our stock
price.
10
We rely on continued market acceptance of our ABTS system and our
ability to complete certain enhancements.
Continued
market acceptance of the ABTS family is subject to a number of
risks. It is important that we achieve customer acceptance,
customer satisfaction and increased market acceptance as we add new
features and enhancements to the ABTS product. To date, we have
shipped ABTS systems to customers worldwide for use in both
reliability and production applications. We have had a
strengthening of ABTS product sales last two fiscal years. However,
the failure of the ABTS family to grow revenues above current
levels would have a material adverse effect on our future operating
results.
A substantial portion of our net sales is generated by relatively
small volume, high value transactions.
We
derive a substantial portion of our net sales from the sale of a
relatively small number of systems which typically range in
purchase price from approximately $300,000 to well over $1 million
per system. As a result, the loss or deferral of a limited number
of system sales could have a material adverse effect on our net
sales and operating results in a particular period. Most customer
purchase orders are subject to cancellation or rescheduling by the
customer with limited penalties, and, therefore, backlog at any
particular date is not necessarily indicative of actual sales for
any succeeding period. From time to time, cancellations and
rescheduling of customer orders have occurred, and delays by our
suppliers in providing components or subassemblies to us have
caused delays in our shipments of our own products. There can be no
assurance that we will not be materially adversely affected by
future cancellations or rescheduling. For non-standard products
where we have not effectively demonstrated the ability to meet
specifications in the customer environment, we defer revenue until
we have met such customer specifications. Any delay in meeting
customer specifications could have a material adverse effect on our
operating results. A substantial portion of net sales typically are
realized near the end of each quarter. A delay or reduction in
shipments near the end of a particular quarter, due, for example,
to unanticipated shipment rescheduling, cancellations or deferrals
by customers, customer credit issues, unexpected manufacturing
difficulties experienced by us or delays in deliveries by
suppliers, could cause net sales in a particular quarter to fall
significantly below our expectations.
We may experience increased costs associated with new product
introductions.
As
is common with new complex products incorporating leading-edge
technologies, we have encountered reliability, design and
manufacturing issues as we began volume production and initial
installations of certain products at customer sites. Some of these
issues in the past have been related to components and subsystems
supplied to us by third parties who have in some cases limited the
ability of us to address such issues promptly. This process in the
past required and in the future is likely to require us to incur
un-reimbursed engineering expenses and to experience larger than
anticipated warranty claims which could result in product returns.
In the early stages of product development there can be no
assurance that we will discover any reliability, design and
manufacturing issues or, that if such issues arise, that they can
be resolved to the customers’ satisfaction or that the
resolution of such problems will not cause us to incur significant
development costs or warranty expenses or to lose significant sales
opportunities.
We sell our products and services worldwide, and our business is
subject to risks inherent in conducting business activities in
geographic regions outside of the United States.
Approximately
71%, 59%, and 80% of our net sales for fiscal 2018, 2017 and 2016,
respectively, were attributable to sales to customers for delivery
outside of the United States. We operate a direct sales, service
and limited manufacturing organization in Germany and sales and
service organizations in Japan and Taiwan as well as direct support
through 3
rd
party agreements in
China, South Korea, and the Philippines. We expect that sales of
products for delivery outside of the United States will continue to
represent a substantial portion of our future net sales. Our future
performance will depend, in significant part, upon our ability to
continue to compete in foreign markets which in turn will depend,
in part, upon a continuation of current trade relations between the
United States and foreign countries in which semiconductor
manufacturers or assemblers have operations. A change toward more
protectionist trade legislation in either the United States or such
foreign countries, such as a change in the current tariff
structures, export compliance or other trade policies, could
adversely affect our ability to sell our products in foreign
markets. In addition, we are subject to other risks associated with
doing business internationally, including longer receivable
collection periods and greater difficulty in accounts receivable
collection, the burden of complying with a variety of foreign laws,
difficulty in staffing and managing global operations, risks of
civil disturbance or other events which may limit or disrupt
markets, international exchange restrictions, changing political
conditions and monetary policies of foreign
governments.
11
Approximately
100%, 0% and 0% of our net sales for fiscal 2018 were denominated
in U.S. Dollars, Euros and Japanese Yen, respectively. Although the
percentages of net sales denominated in Euros and Japanese Yen were
small in fiscal 2018, they have been larger in the past and could
become significant again in the future. A large percentage of net
sales to European customers are denominated in U.S. Dollars, but
sales to many Japanese customers are denominated in Japanese Yen.
Because a substantial portion of our net sales is from sales of
products for delivery outside the United States, an increase in the
value of the U.S. Dollar relative to foreign currencies would
increase the cost of our products compared to products sold by
local companies in such markets. In addition, since the price is
determined at the time a purchase order is accepted, we are exposed
to the risks of fluctuations in the U.S. Dollar exchange rate
during the lengthy period from the date a purchase order is
received until payment is made. This exchange rate risk is
partially offset to the extent our foreign operations incur
expenses in the local currency. To date, we have not invested in
any instruments designed to hedge currency risks. Our operating
results could be adversely affected by fluctuations in the value of
the U.S. Dollar relative to other currencies.
We purchase materials from suppliers worldwide, which subjects the
Company to increased risk.
We
purchase components, sub-assemblies, and chambers from suppliers
outside the United States. Increases in tariffs, additional taxes,
or trade barriers may result in an increase in our manufacturing
costs. A decrease in the value of the U.S. Dollar relative to
foreign currencies would increase the cost of our materials. Should
the Company increase its sales prices to recover the increase in
costs, this could result in a decrease in the competitiveness of
our products. In addition, we are subject to other risks associated
with purchasing materials from suppliers worldwide. Government
authorities may also implement protectionist policies or impose
limitations on the transfer of intellectual property. This may
limit our ability to obtain products from certain geographic
regions and require us to identify and qualify new suppliers. The
process of qualifying suppliers could be lengthy, and no assurance
can be given that any additional sources would be available to us
on a timely basis. Changes in trade relations, currency
fluctuations, or protectionist policies could have a material
adverse effect on our business, financial condition or results of
operations.
The Company is exposed to cybersecurity threats or
incidents.
We
collect, maintain, and transmit data on information systems. These
systems include those owned and maintained by the Company or by
third parties. In addition, we use cloud-based enterprise resource
planning, ERP, software to manage the business integrating all
facets of operations, including manufacturing, finance, and sales
and marketing. The data maintained on these systems includes
confidential and proprietary information belonging to Aehr, our
customers, suppliers, and others. While the Company devotes
significant resources to protect its systems and data from
unauthorized access or misuse, we are exposed to cybersecurity
risks. Our systems are subject to computer viruses, data breach,
phishing schemes, and other malicious software programs or attacks.
We have experienced cyber threats and incidents in the past.
Although past threats and incidents have not resulted in a material
adverse effect, cybersecurity incidents may result in business
disruption, loss of data, or unauthorized access to intellectual
property which could adversely affect our business.
Our industry is subject to rapid technological change and our
ability to remain competitive depends on our ability to introduce
new products in a timely manner.
The
semiconductor equipment industry is subject to rapid technological
change and new product introductions and enhancements. Our ability
to remain competitive depends in part upon our ability to develop
new products and to introduce them at competitive prices and on a
timely and cost-effective basis. Our success in developing new and
enhanced products depends upon a variety of factors, including
product selection, timely and efficient completion of product
design, timely and efficient implementation of manufacturing and
assembly processes, product performance in the field and effective
sales and marketing. Because new product development commitments
must be made well in advance of sales, new product decisions must
anticipate both future demand and the technology that will be
available to supply that demand. Furthermore, introductions of new
and complex products typically involve a period in which design,
engineering and reliability issues are identified and addressed by
our suppliers and by us. There can be no assurance that we will be
successful in selecting, developing, manufacturing and marketing
new products that satisfy market demand. Any such failure would
materially and adversely affect our business, financial condition
and results of operations.
Because
of the complexity of our products, significant delays can occur
between a product’s introduction and the commencement of the
volume production of such product. We have experienced, from time
to time, significant delays in the introduction of, and technical
and manufacturing difficulties with, certain of our products and
may experience delays and technical and manufacturing difficulties
in future introductions or volume production of our new products.
Our inability to complete new product development, or to
manufacture and ship products in time to meet customer requirements
would materially adversely affect our business, financial condition
and results of operations.
12
Our dependence on subcontractors and sole source suppliers may
prevent us from delivering our products on a timely basis and
expose us to intellectual property infringement.
We
rely on subcontractors to manufacture many of the components or
subassemblies used in our products. Our FOX and ABTS systems,
WaferPak contactors and DiePak carriers contain several components,
including environmental chambers, power supplies, high-density
interconnects, wafer contactors, module contactors, signal
distribution substrates, WaferPak Aligners, DiePak Loaders and
certain ICs that are currently supplied by only one or a limited
number of suppliers. Our reliance on subcontractors and single
source suppliers involves a number of significant risks, including
the loss of control over the manufacturing process, the potential
absence of adequate capacity and reduced control over delivery
schedules, manufacturing yields, quality and costs. In the event
that any significant subcontractor or single source supplier is
unable or unwilling to continue to manufacture subassemblies,
components or parts in required volumes, we would have to identify
and qualify acceptable replacements. The process of qualifying
subcontractors and suppliers could be lengthy, and no assurance can
be given that any additional sources would be available to us on a
timely basis. Any delay, interruption or termination of a supplier
relationship could adversely affect our ability to deliver
products, which would harm our operating results.
Our
suppliers manufacture components, tooling, and provide engineering
services. During this process, our suppliers are allowed access to
our intellectual property. While we maintain patents to protect
from intellectual property infringement, there can be no assurance
that technological information gained in the manufacture of our
products will not be used to develop a new product, improve
processes or techniques which compete against our products.
Litigation may be necessary to enforce or determine the validity
and scope of our proprietary rights, and there can be no assurance
that our intellectual property rights, if challenged, will be
upheld as valid.
Periodic economic and semiconductor industry downturns could
negatively affect our business, results of operations and financial
condition.
Periodic
global economic and semiconductor industry downturns have
negatively affected and could continue to negatively affect our
business, results of operations, and financial condition. Financial
turmoil in the banking system and financial markets has resulted,
and may result in the future, in a tightening of the credit
markets, disruption in the financial markets and global economy
downturn. These events may contribute to significant slowdowns in
the industry in which we operate. Difficulties in obtaining capital
and deteriorating market conditions can pose the risk that some of
our customers may not be able to obtain necessary financing on
reasonable terms, which could result in lower sales. Customers with
liquidity issues may lead to additional bad debt
expense.
Turmoil
in the international financial markets has resulted, and may result
in the future, in dramatic currency devaluations, stock market
declines, restriction of available credit and general financial
weakness. In addition, flash memory and other similar device prices
have historically declined, and will likely do so again in the
future. These developments may affect us in several ways. The
market for semiconductors and semiconductor capital equipment has
historically been cyclical, and we expect this to continue in the
future. The uncertainty of the semiconductor market may cause some
manufacturers in the future to further delay capital spending
plans. Economic conditions may also affect the ability of our
customers to meet their payment obligations, resulting in
cancellations or deferrals of existing orders and limiting
additional orders. In addition, some governments have subsidized
portions of fabrication facility construction, and financial
turmoil may reduce these governments’ willingness to continue
such subsidies. Such developments could have a material adverse
effect on our business, financial condition and results of
operations.
The
current economic conditions and uncertainty about future economic
conditions make it challenging for us to forecast our operating
results, make business decisions, and identify the risks that may
affect our business, financial condition and results of operations.
If such conditions recur, and we are not able to timely and
appropriately adapt to changes resulting from the difficult
macroeconomic environment, our business, financial condition or
results of operations may be materially and adversely
affected.
Future changes in semiconductor technologies may make our products
obsolete.
Future
improvements in semiconductor design and manufacturing technology
may reduce or eliminate the need for our products. For example,
improvements in semiconductor process technology and improvements
in conventional test systems, such as reduced cost or increased
throughput, may significantly reduce or eliminate the market for
one or more of our products. If we are not able to improve our
products or develop new products or technologies quickly enough to
maintain a competitive position in our markets, our business may
decline.
13
If we are not able to reduce our operating expenses sufficiently
during periods of weak revenue, or if we utilize significant
amounts of cash to support operating losses, we may erode our cash
resources and may not have sufficient cash to operate our
business.
In
recent years, in the face of a downturn in our business and a
decline in our net sales, we implemented a variety of cost controls
and restructured our operations with the goal of reducing our
operating costs to position ourselves to more effectively meet the
needs of the then weak market for test and burn-in equipment. While
we took significant steps to minimize our expense levels and to
increase the likelihood that we would have sufficient cash to
support operations during the downturn, from fiscal 2009 through
fiscal 2017, with the exception of fiscal 2014, we experienced
operating losses. We anticipate that our existing cash balance
together with income from operations, collections of existing
accounts receivable, revenue from our existing backlog of products,
the sale of inventory on hand, and deposits and down payments
against significant orders will be adequate to meet our working
capital and capital equipment requirements. Depending on our rate
of growth and profitability, and our ability to obtain significant
orders with down payments, we may require additional equity or debt
financing to meet our working capital requirements or capital
equipment needs. There can be no assurance that additional
financing will be available when required, or if available, that
such financing can be obtained on terms satisfactory to
us.
Our stock price may fluctuate.
The
price of our common stock has fluctuated in the past and may
fluctuate significantly in the future. We believe that factors such
as announcements of developments related to our business,
fluctuations in our operating results, general conditions in the
semiconductor and semiconductor equipment industries as well as the
worldwide economy, announcement of technological innovations, new
systems or product enhancements by us or our competitors,
fluctuations in the level of cooperative development funding,
acquisitions, changes in governmental regulations, developments in
patents or other intellectual property rights and changes in our
relationships with customers and suppliers could cause the price of
our common stock to fluctuate substantially. In addition, in recent
years the stock market in general, and the market for small
capitalization and high technology stocks in particular, have
experienced extreme price fluctuations which have often been
unrelated to the operating performance of the affected companies.
Such fluctuations could adversely affect the market price of our
common stock.
We depend on our key personnel and our success depends on our
ability to attract and retain talented employees.
Our
success depends to a significant extent upon the continued service
of Gayn Erickson, our President and Chief Executive Officer, as
well as other executive officers and key employees. We do not
maintain key person life insurance for our benefit on any of our
personnel, and none of our employees are subject to a
non-competition agreement with us. The loss of the services of any
of our executive officers or a group of key employees could have a
material adverse effect on our business, financial condition and
operating results. Our future success will depend in significant
part upon our ability to attract and retain highly skilled
technical, management, sales and marketing personnel. There is a
limited number of personnel with the requisite skills to serve in
these positions, and it has become increasingly difficult for us to
hire such personnel. Competition for such personnel in the
semiconductor equipment industry is intense, and there can be no
assurance that we will be successful in attracting or retaining
such personnel. Changes in management could disrupt our operations
and adversely affect our operating results.
We may be subject to litigation relating to intellectual property
infringement which would be time-consuming, expensive and a
distraction from our business.
If
we do not adequately protect our intellectual property, competitors
may be able to use our proprietary information to erode our
competitive advantage, which could harm our business and operating
results. Litigation may be necessary to enforce or determine the
validity and scope of our proprietary rights, and there can be no
assurance that our intellectual property rights, if challenged,
will be upheld as valid. Such litigation could result in
substantial costs and diversion of resources and could have a
material adverse effect on our operating results, regardless of the
outcome of the litigation. In addition, there can be no assurance
that any of the patents issued to us will not be challenged,
invalidated or circumvented or that the rights granted thereunder
will provide competitive advantages to us.
14
There
are no pending claims against us regarding infringement of any
patents or other intellectual property rights of others. However,
in the future we may receive communications from third parties
asserting intellectual property claims against us. Such claims
could include assertions that our products infringe, or may
infringe, the proprietary rights of third parties, requests for
indemnification against such infringement or suggestions that we
may be interested in acquiring a license from such third parties.
There can be no assurance that any such claim will not result in
litigation, which could involve significant expense to us, and, if
we are required or deem it appropriate to obtain a license relating
to one or more products or technologies, there can be no assurance
that we would be able to do so on commercially reasonable terms, or
at all.
While we believe we have complied with all applicable environmental
laws, our failure to do so could adversely affect our business as a
result of having to pay substantial amounts in damages or
fees.
Federal, state and local regulations
impose various controls on the use, storage, discharge, handling,
emission, generation, manufacture and disposal of toxic and other
hazardous substances used in our operations. We believe that our
activities conform in all material respects to current
environmental and land use regulations applicable to our operations
and our current facilities, and that we have obtained environmental
permits necessary to conduct our business. Nevertheless, failure to
comply with current or future regulations could result in
substantial fines, suspension of production, alteration of our
manufacturing processes or cessation of operations. Such
regulations could require us to acquire expensive remediation
equipment or to incur substantial expenses to comply with
environmental regulations. Any failure to control the use, disposal
or storage of or adequately restrict the discharge of, hazardous or
toxic substances could subject us to significant
liabilities.
If we fail to maintain effective internal control over financial
reporting in the future, the accuracy and timing of our financial
reporting may be adversely affected.
We
are required to comply with Section 404 of the Sarbanes-Oxley Act
of 2002. The provisions of the act require, among other things,
that we maintain effective internal control over financial
reporting and disclosure controls and procedures. Preparing our
financial statements involves a number of complex processes, many
of which are done manually and are dependent upon individual data
input or review. These processes include, but are not limited to,
calculating revenue, deferred revenue and inventory costs. While we
continue to automate our processes and enhance our review and put
in place controls to reduce the likelihood for errors, we expect
that for the foreseeable future, many of our processes will remain
manually intensive and thus subject to human error.
Our common stock may be delisted from The NASDAQ Capital Market if
we cannot maintain compliance with NASDAQ’s continued listing
requirements.
In
order to maintain our listing on The NASDAQ Capital Market, we are
required to maintain compliance with NASDAQ’s continued
listing requirements. The continued listing requirements include,
among others, a minimum bid price of $1.00 per share and any of:
(i) a minimum stockholders’ equity of $2.5 million; (ii) a
market value of listed securities of at least $35 million; or (iii)
net income from continuing operations of $500,000 in the most
recently completed fiscal year or in two of the last three fiscal
years. There are no assurances that we will be able to sustain
long-term compliance with NASDAQ’s continued listing
requirements. On April 19, 2016, we were notified by NASDAQ that we
were no longer in compliance with NASDAQ’s continued listing
requirements as we did not have a minimum stockholders’
equity of $2.5 million. On October 3, 2016, we were notified by
NASDAQ that we had regained compliance with NASDAQ’s
continued listing requirements. If we fail to maintain compliance
with the applicable NASDAQ continued listing requirements, our
stock may be delisted.
If
we are delisted, we would expect our common stock to be traded in
the over-the-counter market, which could make trading our common
stock more difficult for investors, potentially leading to declines
in our share price and liquidity. Delisting from The NASDAQ Capital
Market would also constitute an event of default under our
convertible notes. In addition, delisting could result in negative
publicity and make it more difficult for us to raise additional
capital.

The
Company’s principal administrative and production facilities
are located in Fremont, California, in a 51,289 square foot
building. The Company’s lease was renewed in February 2018

At
August 3, 2018, the Company had 139 holders of record of its common
stock. A substantially greater number of holders of the
Company’s common stock are “street name” or
beneficial holders whose shares are held by banks, brokers and
other financial institutions.
The
Company has not paid cash dividends on its common stock or other
securities. The Company currently anticipates that it will retain
its future earnings, if any, for use in the expansion and operation
of its business and does not anticipate paying any cash dividends
on its common stock in the foreseeable future.
The
Company did not repurchase any of its common stock during the
fiscal year ended May 31, 2018.
PERFORMANCE
MEASUREMENT COMPARISON
The
following graph shows a comparison of total shareholder return for
holders of the Company's common stock for the last five fiscal
years ended May 31, 2018, compared with the NASDAQ Composite Index
and the Philadelphia Semiconductor Index. The graph assumes that
$100 was invested in the Company's common stock, in the NASDAQ
Composite Index and the Philadelphia Semiconductor Index on May 31,
2013, and that all dividends were reinvested. The Company believes
that while total shareholder return can be an important indicator
of corporate performance, the stock prices of semiconductor
equipment companies like us are subject to a number of
market-related factors other than company performance, such as
competitive announcements, mergers and acquisitions in the
industry, the general state of the economy and the performance of
other semiconductor equipment company stocks. Stock prices and
shareholder returns over the indicated period should not be
considered indicative of future stock prices or shareholder
returns.

The
following discussion and analysis of the financial condition and
results of operations should be read in conjunction with our
“Selected Consolidated Financial Data” and our
consolidated financial statements and related notes included
elsewhere in this Annual Report on Form 10-K.
OVERVIEW
We
were founded in 1977 to develop and manufacture burn-in and test
equipment for the semiconductor industry. Since our inception, we
have over 2,500 systems installed at semiconductor manufacturers,
semiconductor contract assemblers and burn-in and test service
companies worldwide. Our principal products currently are the
Advanced Burn-in and Test System, or ABTS, the FOX full wafer
contact and singulated die/module parallel test and burn-in system,
WaferPak Aligner, WaferPak contactors, DiePak Loader, the DiePak
carriers and test fixtures.
Our
net sales consist primarily of sales of systems, WaferPak Aligners
and DiePak Loaders, WaferPak contactors, DiePak carriers, test
fixtures, upgrades and spare parts, revenues from service
contracts, and engineering development charges. Our selling
arrangements may include contractual customer acceptance
provisions, which are mostly deemed perfunctory or inconsequential,
and installation of the product occurs after shipment and transfer
of title.
CRITICAL
ACCOUNTING POLICIES AND ESTIMATES
Our
discussion and analysis of our financial condition and results of
operations are based upon our consolidated financial statements,
which have been prepared in accordance with accounting principles
generally accepted in the United States of America. The preparation
of these consolidated financial statements requires us to make
estimates and judgments that affect the reported amounts of assets,
liabilities, revenues and expenses, and related disclosure of
contingent assets and liabilities. On an ongoing basis, we evaluate
our estimates, including those related to customer programs and
incentives, product returns, bad debts, inventories, investments,
income taxes, financing operations, warranty obligations and
long-term service contracts, among others. Our estimates are
derived from historical experience and on various other assumptions
that are believed to be reasonable under the circumstances. Those
results form the basis for making judgments about the carrying
values of assets and liabilities that are not readily apparent from
other sources. Actual results may differ from these estimates under
different assumptions or conditions.
We
believe the following critical accounting policies affect our more
significant judgments and estimates used in the preparation of our
consolidated financial statements.
REVENUE
RECOGNITION
We
recognize revenue upon the shipment of products or the performance
of services when: (1) persuasive evidence of the arrangement
exists; (2) goods or services have been delivered; (3) the price is
fixed or determinable; and (4) collectibility is reasonably
assured. When a sales agreement involves multiple deliverables,
such as extended support provisions, training to be supplied after
delivery of the systems, and test programs specific to
customers’ routine applications, the multiple deliverables
are evaluated to determine the units of accounting. Judgment is
required to properly identify the accounting units of multiple
element transactions and the manner in which revenue is allocated
among the accounting units. Judgments made, or changes to judgments
made, may significantly affect the timing or amount of revenue
recognition.
Revenue
related to the multiple elements is allocated to each unit of
accounting using the relative selling price hierarchy. Consistent
with accounting guidance, the selling price is based upon vendor
specific objective evidence (VSOE). If VSOE is not available, third
party evidence (TPE) is used to establish the selling price. In the
absence of VSOE or TPE, estimated selling price is
used.
During
the first quarter of fiscal 2013, we entered into an agreement with
a customer to develop a next generation FOX system, and we shipped
the first system in July 2016. The project identifies multiple
milestones with values assigned to each. The consideration earned
upon achieving the milestone is required to meet the following
conditions prior to recognition: (i) the value is commensurate with
the vendor’s performance to meet the milestone, (ii) it
relates solely to past performance, (iii) and it is reasonable
relative to all of the deliverables and payment terms within the
arrangement. Revenue is recognized for the milestone upon
acceptance by the customer.
20
We
recognize revenue in certain circumstances before physical delivery
has occurred. In these arrangements, among other things, risk of
ownership has passed to the customer, the customer has made a
written fixed commitment to purchase the products, the customer has
requested the products be held for future delivery as scheduled and
designated by them, and no additional performance obligations exist
by us. For these transactions, the products are segregated from
inventory and normal billing and credit terms granted.
Sales
tax collected from customers is not included in net sales but
rather recorded as a liability due to the respective taxing
authorities. Provisions for the estimated future cost of warranty
and installation are recorded at the time the products are
shipped.
Royalty-based
revenue related to licensing income from performance test boards
and burn-in boards is recognized upon the earlier of the receipt by
us of the licensee’s report related to its usage of the
licensed intellectual property or upon payment by the
licensee.
Our
terms of sales with distributors are generally Free on Board, or
FOB, shipping point with payment due within 60 days. All products
go through in-house testing and verification of specifications
before shipment. Apart from warranty reserves, credits issued have
not been material as a percentage of net sales. Our distributors do
not generally carry inventories of our products. Instead, the
distributors place orders with us at or about the time they receive
orders from their customers. Our shipment terms to our distributors
do not provide for credits or rights of return. Because our
distributors do not generally carry inventories of our products,
they do not have rights to price protection or to return products.
At the time we ship products to the distributors, the price is
fixed. Subsequent to the issuance of the invoice, there are no
discounts or special terms. We do not give the buyer the right to
return the product or to receive future price concessions. Our
arrangements do not include vendor consideration.
ALLOWANCE
FOR DOUBTFUL ACCOUNTS
We
maintain an allowance for doubtful accounts to reserve for
potentially uncollectible trade receivables. We also review our
trade receivables by aging category to identify specific customers
with known disputes or collection issues. We exercise judgment when
determining the adequacy of these reserves as we evaluate
historical bad debt trends, general economic conditions in the
United States and internationally and changes in customer financial
conditions. Uncollectible receivables are recorded as bad debt
expense when all efforts to collect have been exhausted and
recoveries are recognized when they are received.
WARRANTY
OBLIGATIONS
We
provide and record the estimated cost of product warranties at the
time revenues are recognized on products shipped. While we engage
in extensive product quality programs and processes, including
actively monitoring and evaluating the quality of our component
suppliers, our warranty obligation is affected by product failure
rates, material usage and service delivery costs incurred in
correcting a product failure. Our estimate of warranty reserve is
based on management’s assessment of future warranty
obligations and on historical warranty obligations. Should actual
product failure rates, material usage or service delivery costs
differ from our estimates, revisions to the estimated warranty
liability would be required, which could affect how we account for
expenses.
INVENTORY
OBSOLESCENCE
In
each of the last three fiscal years, we have written down our
inventory for estimated obsolescence or unmarketable inventory by
an amount equal to the difference between the cost of inventory and
the estimated market value based upon assumptions about future
demand and market conditions. If future market conditions are less
favorable than those projected by management, additional inventory
write-downs may be required.
INCOME
TAXES
Income
taxes have been provided using the liability method whereby
deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets and
liabilities and net operating loss and tax credit carryforwards
measured using the enacted tax rates and laws that will be in
effect when the differences are expected to reverse or the
carryforwards are utilized. Valuation allowances are established
when it is determined that it is more likely than not that such
assets will not be realized.
A
full valuation allowance was established against all deferred tax
assets, as management determined that it is more likely than not
that deferred tax assets will not be realized, as of May 31, 2018
and 2017.
21
We
account for uncertain tax positions consistent with authoritative
guidance. The guidance prescribes a “more likely than
not” recognition threshold and measurement attribute for the
financial statement recognition and measurement of a tax position
taken or expected to be taken in a tax return. We do not expect any
material change in its unrecognized tax benefits over the next
twelve months. We recognize interest and penalties related to
unrecognized tax benefits as a component of income
taxes.
Although
we file U.S. federal, various state and foreign tax returns, our
only major tax jurisdictions are the United States, California,
Germany and Japan. Tax years 1996 – 2017 remain subject to
examination by the appropriate governmental agencies due to tax
loss carryovers, research and development tax credits, or other tax
attributes from those years.
STOCK-BASED
COMPENSATION EXPENSE
Stock-based
compensation expense consists of expenses for stock options,
restricted stock units, or RSUs, and employee stock purchase plan,
or ESPP, purchase rights. Stock-based compensation cost for stock
options and ESPP purchase rights is measured at each grant date,
based on the fair value of the award using the Black-Scholes option
valuation model, and is recognized as expense over the
employee’s requisite service period. This model was developed
for use in estimating the value of publicly traded options that
have no vesting restrictions and are fully transferable. Our
employee stock options have characteristics significantly different
from those of publicly traded options. For RSUs, stock-based
compensation cost is based on the fair value of our common stock at
the grant date. All of our stock-based compensation is accounted
for as an equity instrument.
The
fair value of each option grant and the right to purchase shares
under our ESPP are estimated on the date of grant using the
Black-Scholes option valuation model with assumptions concerning
expected term, stock price volatility, expected dividend yield,
risk-free interest rate and the expected life of the award. See
Notes 10 to our consolidated financial statements for detailed
information relating to stock-based compensation and the stock
option plan and the ESPP.

FISCAL
YEAR ENDED MAY 31, 2018 COMPARED TO FISCAL YEAR ENDED MAY 31,
2017
NET
SALES. Net sales increased to $29.6 million for the fiscal year
ended May 31, 2018 from $18.9 million for the fiscal year ended May
31, 2017, an increase of 56.4%. The increase in net sales in fiscal
2018 resulted primarily from increases in net sales of both our
Test During Burn-in (TDBI) products and wafer-level products. Net
sales of the TDBI products for fiscal 2018 were $16.5 million, and
increased approximately $7.3 million from fiscal 2017. Net sales of
the wafer-level products for fiscal 2018 were $13.1 million, and
increased approximately $3.5 million from fiscal 2017.
GROSS
PROFIT. Gross profit increased to $12.4 million for the fiscal year
ended May 31, 2018 from $6.8 million for the fiscal year ended May
31, 2017, an increase of 82.7%. Gross profit margin increased to
41.9% for the fiscal year ended May 31, 2018 from 35.9% for the
fiscal year ended May 31, 2017.
The increase in gross
profit margin was primarily the result of manufacturing
efficiencies due to an increase in net sales.
SELLING,
GENERAL AND ADMINISTRATIVE. SG&A expenses were $7.3 million for
the fiscal year ended May 31, 2018, compared with $7.1 million for
the fiscal year ended May 31, 2017, an increase of 3.4%. The
increase in SG&A expenses was primarily due to increases in
employment related expenses.
RESEARCH
AND DEVELOPMENT. R&D expenses decreased to $4.2 million for the
fiscal year ended May 31, 2018 from $4.7 million for the fiscal
year ended May 31, 2017, a decrease of 10.2%. The decrease in
R&D expenses was primarily due to decreases in project
expenses.
INTEREST
EXPENSE. Interest expense decreased to $399,000 for the fiscal year
ended May 31, 2018 from $678,000 for the fiscal year ended May 31,
2017. The decrease in interest expense for the fiscal year ended
May 31, 2018 was primarily due to the debt issuance costs related
to the convertible notes becoming fully amortized at the end of
fiscal 2017.
OTHER
EXPENSE, NET. Other expense, net was $61,000 and $21,000 for the
fiscal year ended May 31, 2018 and 2017, respectively.
The change in other
expense was due primarily to losses realized in connection with the
fluctuation in the value of the dollar compared to foreign
currencies during the referenced periods.
INCOME
TAX BENEFIT (EXPENSE). Income tax benefit was $73,000 for the
fiscal year ended May 31, 2018 compared with income tax expense of
$25,000 for the fiscal year ended May 31, 2017. The income tax
benefit in the fiscal year ended May 31, 2018 was primarily due to
the impact of the “Tax Cuts and Jobs Act” enacted on
December 22, 2017, specifically, the provision which made our
alternative minimum tax credit refundable by 2022.
FISCAL
YEAR ENDED MAY 31, 2017 COMPARED TO FISCAL YEAR ENDED MAY 31,
2016
NET
SALES. Net sales increased to $18.9 million for the fiscal year
ended May 31, 2017 from $14.5 million for the fiscal year ended May
31, 2016, an increase of 30.3%. The increase in net sales in fiscal
2017 resulted primarily from increases in net sales of both our
wafer-level products and Test During Burn-in (TDBI) products. Net
sales of the wafer-level products for fiscal 2017 were $9.6
million, and increased approximately $0.9 million from fiscal 2016.
Net sales of the TDBI products for fiscal 2017 were $9.2 million,
and increased approximately $3.4 million from fiscal
2016.
GROSS
PROFIT. Gross profit increased to $6.8 million for the fiscal year
ended May 31, 2017 from $5.1 million for the fiscal year ended May
31, 2016, an increase of 31.8%. Gross profit margins for the fiscal
years ended May 31, 2017 and 2016 were 35.9% and 35.5%,
respectively.
SELLING,
GENERAL AND ADMINISTRATIVE. SG&A expenses were $7.1 million for
the fiscal year ended May 31, 2017, compared with $7.0 million for
the fiscal year ended May 31, 2016, an increase of 1.1%. The
increase in SG&A expenses was primarily due to increases in
employment related expenses.
RESEARCH
AND DEVELOPMENT. R&D expenses increased to $4.7 million for the
fiscal year ended May 31, 2017 from $4.3 million for the fiscal
year ended May 31, 2016, an increase of 7.7%. Higher R&D
expenses in the fiscal year ended May 31, 2017 were primarily due
to increases of $0.2 million in employment related expenses and
$0.1 million in project expenses.
INTEREST
EXPENSE. Interest expense increased to $678,000 for the fiscal year
ended May 31, 2017 from $605,000 for the fiscal year ended May 31,
2016. The increase in interest expense for the fiscal year ended
May 31, 2017 was primarily due to higher average
borrowings.
OTHER
(EXPENSE) INCOME, NET. Other expense, net was $21,000 and $16,000
for the fiscal year ended May 31, 2017 and 2016,
respectively.
The change in other
expense was due primarily to losses realized in connection with the
fluctuation in the value of the dollar compared to foreign
currencies during the referenced periods.
23
INCOME
TAX EXPENSE. Income tax expense was $25,000 and $10,000 for the
fiscal year ended May 31, 2017 and 2016, respectively.
LIQUIDITY
AND CAPITAL RESOURCES
We
consider cash and cash equivalents as liquid and available for use.
As of May 31, 2018 and 2017, we had $16.8 million and $17.8
million, respectively, in cash and cash equivalents.
Net
cash used in operating activities was $1.4 million and $4.5 million
for the fiscal years ended May 31, 2018 and 2017, respectively. For
the fiscal year ended May 31, 2018, net cash used in operating
activities was primarily the result of the net income of $0.5
million, as adjusted to exclude the effect of non-cash charge of
stock-based compensation expense of $1.0 million, depreciation and
amortization of $0.4 million, and a decrease in accounts receivable
of $1.3 million. Other changes in cash from operations primarily
resulted from an increase in inventories of $2.1 million, a
decrease in customer deposits and deferred revenue of $1.5 million,
as well as the decrease in accounts payable of $1.1 million. The
decrease in accounts receivable was primarily due to improvements
in customer payment terms. The increase in inventories is to
support future shipments for customer orders. The decrease in
customer deposits and deferred revenue was primarily due to the
decrease in backlog of customer orders with down payments. The
decrease in accounts payable was primarily due to the down payments
applied toward vendor invoices. For the fiscal year ended May 31,
2017, net cash used in operating activities was primarily the
result of the net loss of $5.7 million, as adjusted to exclude the
effect of non-cash charge of stock-based compensation expense of
$1.0 million, and an increase in accounts receivable of $3.5
million, partially offset by a decrease in inventories of $0.4
million. Other changes in cash from operations resulted from an
increase in accounts payable as well as an increase in customer
deposits and deferred revenue of $1.7 million each. The increase in
accounts receivable was primarily due to an increase in sales. The
decrease in inventories is primarily due to the sales of systems
on-hand at the beginning of the period. The increase in accounts
payable was primarily due to higher expenditures associated with
higher revenue. The increase in customer deposits and deferred
revenue was primarily due to the receipt of additional down
payments from certain customers.
Net
cash used in investing activities was $0.6 million and $0.5 million
for the fiscal year ended May 31, 2018 and 2017, respectively. Net
cash used in investing activities for the fiscal year ended May 31,
2018 and 2017 was due to the purchases of property and
equipment.
Financing
activities provided net cash of $0.9 million for the fiscal year
ended May 31, 2018 as compared to $21.8 million for the fiscal year
ended May 31, 2017. Net cash provided by financing activities
during the fiscal year ended May 31, 2018 was primarily due to the
proceeds from issuance of common stock under employee plans. Net
cash provided by financing activities during the fiscal year ended
May 31, 2017 was primarily due to the net proceeds of $15.8 million
from the sale of our common stock in a public offering that closed
on April 19, 2017, the net proceeds of $5.3 million from the sale
of our common stock in a private placement transaction with certain
institutional and accredited investors that closed on September 28,
2016, and $0.7 million in proceeds from issuance of common stock
under employee plans.
The
effect of fluctuation in exchange rates increased cash by $43,000
and $1,000 for the fiscal year ended May 31, 2018 and 2017,
respectively. The changes were due to the fluctuation in the value
of the dollar compared to foreign currencies.
As
of May 31, 2018 and 2017, we had working capital of $18.3 million
and $21.5 million, respectively.
For
the fiscal year ended May 31, 2016, net cash used in operating
activities was primarily the result of the net loss of $6.8
million, as adjusted to exclude the effect of non-cash charges
including stock-based compensation expense of $1.0 million, and
depreciation and amortization of $0.2 million. Other changes in
cash from operations resulted from a decrease in accounts
receivable of $0.9 million, and increases in accounts payable of
$0.6 million and accrued expenses of $0.5 million, offset by a
decrease in customer deposits and deferred revenue of $2.9 million.
The decrease in accounts receivable was primarily due to
improvements in customer payment terms. The increases in accounts
payable and accrued expenses were primarily due to higher
expenditures associated with higher revenue. The decrease in
customer deposits and deferred revenue was primarily due to the
decrease in backlog of customer orders with down
payments.
Net
cash used in investing activities was $0.9 million for the fiscal
year ended May 31, 2016 was due to the purchase of property and
equipment.
Net
cash provided by financing activities of $2.5 million during the
fiscal year ended May 31, 2016 was due to net borrowings under the
credit facility of $2.0 million, and $0.5 million in proceeds from
issuance of common stock under
employee plans.
Refer to Note 8 of Notes to Consolidated Financial Statements,
“LONG-TERM DEBT”, for further discussion of the Credit
Facility.
24
We
lease our manufacturing and office space under operating leases. We
entered into a non-cancelable operating lease agreement for our
United States manufacturing and office facilities, which was
renewed in February 2018 and expires in July 2023. Under the lease
agreement, we are responsible for payments of utilities, taxes and
insurance.
From
time to time, we evaluate potential acquisitions of businesses,
products or technologies that complement our business. If
consummated, any such transactions may use a portion of our working
capital or require the issuance of equity. We have no present
understandings, commitments or agreements with respect to any
material acquisitions.
We
anticipate that the existing cash balance together with income from
operations, collections of existing accounts receivable, revenue
from our existing backlog of products, the sale of inventory on
hand, and deposits and down payments against significant orders
will be adequate to meet our liquidity requirements for the next 12
months.
OFF-BALANCE
SHEET FINANCING
We
have not entered into any off-balance sheet financing arrangements
and have not established any special purpose or variable interest
entities.

(2)
Shown above are our binding purchase obligations. The large
majority of our purchase orders are cancelable by either party,
which if canceled may result in a negotiation with the vendor to
determine if there shall be any restocking or cancellation fees
payable to the vendor.
In
the normal course of business to facilitate sales of our products,
we indemnify other parties, including customers, with respect to
certain matters. We have agreed to hold the other party harmless
against losses arising from a breach of representations or
covenants, or from intellectual property infringement or other
claims. These agreements may limit the time period within which an
indemnification claim can be made and the amount of the claim. In
addition, we have entered into indemnification agreements with our
officers and directors, and our bylaws contain similar
indemnification obligations to our agents.
It
is not possible to determine the maximum potential amount under
these indemnification agreements due to the limited history of
prior indemnification claims and the unique facts and circumstances
involved in each particular agreement. To date, our payments under
these agreements have not had a material impact on our operating
results, financial position or cash flows.
RECENT
ACCOUNTING PRONOUNCEMENTS:
For
a description of recent accounting pronouncements, including the
expected dates of adoption and estimated effects, if any, on our
consolidated financial statements, see Note 1, “Organization
and Summary of Significant Accounting Policies,” of the Notes
to Consolidated Financial Statements.
25
We
had no holdings of derivative financial or commodity instruments at
May 31, 2018.
We
are exposed to financial market risks, including changes in
interest rates and foreign currency exchange rates. We only invest
our short-term excess cash in government-backed securities with
maturities of 18 months or less. We do not use any financial
instruments for speculative or trading purposes. Fluctuations in
interest rates would not have a material effect on our financial
position, results of operations or cash flows.
A
majority of our revenue and capital spending is transacted in U.S.
Dollars. We, however, enter into transactions in other currencies,
primarily Euros and Japanese Yen. Since the price is determined at
the time a purchase order is accepted, we are exposed to the risks
of fluctuations in the foreign currency-U.S. Dollar exchange rates
during the lengthy period from purchase order to ultimate payment.
This exchange rate risk is partially offset to the extent that our
subsidiaries incur expenses payable in their local currency. To
date, we have not invested in instruments designed to hedge
currency risks. In addition, our subsidiaries typically carry debt
or other obligations due to us that may be denominated in either
their local currency or U.S. Dollars. Since our subsidiaries’
financial statements are based in their local currency and our
condensed consolidated financial statements are based in U.S.
Dollars, our subsidiaries and we recognize foreign exchange gains
or losses in any period in which the value of the local currency
rises or falls in relation to the U.S. Dollar. A 10% decrease in
the value of the subsidiaries’ local currency as compared
with the U.S. Dollar would not be expected to result in a
significant change to our net income or loss. There have been no
material changes in our risk exposure since the end of the last
fiscal year, nor are any material changes to our risk exposure
anticipated.

Report Of Independent Registered Public Accounting
Firm
To the Stockholders and Board of Directors of
Aehr Test Systems
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of
Aehr Test Systems and its subsidiaries (the “Company”)
as of May 31, 2018 and 2017, the related consolidated statements of
operations, comprehensive income (loss), shareholders’
equity, and cash flows for each of the three years in the period
ended May 31, 2018, and the related notes (collectively referred to
as the “consolidated financial statements”). In our
opinion, the consolidated financial statements present fairly, in
all material respects, the financial position of the Company as of
May 31, 2018 and 2017, and the results of its operations and its
cash flows for each of the three years in the period ended May 31,
2018, in conformity with accounting principles generally accepted
in the United States of America.
Basis for Opinion
These consolidated financial statements are the responsibility of
the Company’s management. Our responsibility is to express an
opinion on the Company’s consolidated financial statements
based on our audits. We are a public accounting firm registered
with the Public Company Accounting Oversight Board (United States)
(“PCAOB”) and are required to be independent with
respect to the Company in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the
PCAOB. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the consolidated
financial statements are free of material misstatement, whether due
to error or fraud. The Company is not required to have, nor were we
engaged to perform, an audit of its internal control over financial
reporting. As part of our audits, we are required to obtain an
understanding of internal control over financial reporting but not
for the purpose of expressing an opinion on the effectiveness of
the Company’s internal control over financial reporting.
Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of
material misstatement of the consolidated financial statements,
whether due to error or fraud, and performing procedures that
respond to those risks. Such procedures included examining, on a
test basis, evidence regarding the amounts and disclosures in the
consolidated financial statements. Our audits also included
evaluating the accounting principles used and significant estimates
made by management, as well as evaluating the overall presentation
of the consolidated financial statements. We believe that our
audits provide a reasonable basis for our opinion.
/s/ BPM LLP
We have served as the Company’s auditor since
2005.

AEHR TEST SYSTEMS AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES:
BUSINESS:
Aehr
Test Systems (the “Company”) was incorporated in
California in May 1977 and primarily designs, engineers and
manufactures test and burn-in equipment used in the semiconductor
industry. The Company’s principal products are the Advanced
Burn-In and Test System, or ABTS, the FOX full wafer contact
parallel test and burn-in systems, the MAX burn-in system, WaferPak
full wafer contactor, the DiePak carrier and test
fixtures.
LIQUIDITY:
Since
inception, the Company has incurred substantial cumulative losses
and negative cash flows from operations. In response, the Company
took steps to minimize expense levels, entered into credit
arrangements, and raised capital through public and private equity
offerings, to increase the likelihood that it will have sufficient
cash to support operations.
In
April 2017, the Company completed a public offering of its common
stock raising net proceeds to the Company of $15.8 million. At May
31, 2018 the Company had $16.8 million in cash and cash
equivalents. The Company anticipates that the existing cash balance
together with income from operations, collections of existing
accounts receivable, revenue from our existing backlog of products,
the sale of inventory on hand, and deposits and down payments
against significant orders will be adequate to meet its working
capital and capital equipment requirements.
CONSOLIDATION:
The
consolidated financial statements include the accounts of the
Company and both its wholly-owned and majority-owned foreign
subsidiaries. Intercompany accounts and transactions have been
eliminated.
FOREIGN
CURRENCY TRANSLATION AND TRANSACTIONS:
Assets
and liabilities of the Company’s foreign subsidiaries and a
branch office are translated into U.S. Dollars from their
functional currencies of Japanese Yen, Euros and New Taiwan Dollars
using the exchange rate in effect at the balance sheet date.
Additionally, their net sales and expenses are translated using
exchange rates approximating average rates prevailing during the
fiscal year. Translation adjustments that arise from translating
their financial statements from their local currencies to U.S.
Dollars are accumulated and reflected as a separate component of
shareholders’ equity (deficit).
Transaction
gains and losses that arise from exchange rate changes denominated
in currencies other than the local currency are included in the
Consolidated Statements of Operations as incurred. See Note 12 for
the detail of foreign exchange transaction gains and losses for all
periods presented.
USE OF
ESTIMATES:
The
preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities, disclosure of
contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those
estimates. Significant estimates in the Company’s
consolidated financial statements include allowance for doubtful
accounts, valuation of inventory at the lower of cost or market,
and warranty reserves.
CASH
EQUIVALENTS:
Cash
equivalents consist of money market instruments purchased with an
original maturity of three months or less. These investments are
reported at fair value.
ACCOUNTS
RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS:
Accounts
receivable are derived from the sale of products throughout the
world to semiconductor manufacturers, semiconductor contract
assemblers, electronics manufacturers and burn-in and test service
companies. Accounts receivable are recorded at the invoiced amount
and are not interest bearing. The Company maintains an allowance
for doubtful accounts to reserve for potentially uncollectible
trade receivables. The Company also reviews its trade
34
receivables
by aging category to identify specific customers with known
disputes or collection issues. The Company exercises judgment when
determining the adequacy of these reserves as the Company evaluates
historical bad debt trends, general economic conditions in the
United States and internationally, and changes in customer
financial conditions. Uncollectible receivables are recorded as bad
debt expense when all efforts to collect have been exhausted and
recoveries are recognized when they are received. No significant
adjustments to the allowance for doubtful accounts were recorded
during the years ended May 31, 2018, 2017 or 2016.
CONCENTRATION
OF CREDIT RISK:
The
Company sells its products primarily to semiconductor manufacturers
in North America, Asia, and Europe. As of May 31, 2018,
approximately 45%, 0% and 55% of gross accounts receivable were
from customers located in Asia, Europe and North America,
respectively. As of May 31, 2017, approximately 55%, 0% and 45% of
gross accounts receivable were from customers located in Asia,
Europe and North America, respectively. Three customers accounted
for 38%, 32% and 11% of gross accounts receivable as of May 31,
2018. Three customers accounted for 47%, 40% and 11% of gross
accounts receivable as of May 31, 2017. Three customers accounted
for 34%, 26% and 13% of net sales in fiscal 2018. Four customers
accounted for 45%, 19%, 17% and 10% of net sales in fiscal 2017.
The Company performs ongoing credit evaluations of its customers
and generally does not require collateral. The Company uses letter
of credit terms for some of its international
customers.
The
Company’s cash and cash equivalents are generally deposited
with major financial institutions in the United States, Japan,
Germany and Taiwan. The Company invests its excess cash in money
market funds and U.S. Treasury Securities. The money market funds
bear the risk associated with each fund. The money market funds
have variable interest rates. The Company has not experienced any
material losses on its money market funds or short-term cash
deposits.
CONCENTRATION
OF SUPPLY RISK:
The
Company relies on subcontractors to manufacture many of the
components and subassemblies used in its products. Quality or
performance failures of the Company’s products or changes in
its manufacturers’ financial or business condition could
disrupt the Company’s ability to supply quality products to
its customers and thereby have a material and adverse effect on its
business and operating results. Some of the components and
technologies used in the Company’s products are purchased and
licensed from a single source or a limited number of sources. The
loss of any of these suppliers may cause the Company to incur
additional transition costs, result in delays in the manufacturing
and delivery of its products, or cause it to carry excess or
obsolete inventory and could cause it to redesign its
products.
INVENTORIES:
Inventories
include material, labor and overhead, and are stated at the lower
of cost (first-in, first-out method) or net realizable value. Net
realizable value is the estimated selling prices in the ordinary
course of business, less costs of completion, disposal and
transportation. Provisions for excess, obsolete and unusable
inventories are made after management’s evaluation of future
demand and market conditions. The Company adjusts inventory
balances to approximate the lower of its manufacturing costs or net
realizable value. If actual future demand or market conditions
become less favorable than those projected by management,
additional inventory write-downs may be required, and would be
reflected in cost of product revenue in the period the revision is
made.
PROPERTY
AND EQUIPMENT:
Property
and equipment are stated at cost less accumulated depreciation and
amortization. Major improvements are capitalized, while repairs and
maintenance are expensed as incurred. Leasehold improvements are
amortized over the lesser of their estimated useful lives or the
term of the related lease. Furniture and fixtures, machinery and
equipment, and test equipment are depreciated on a straight-line
basis over their estimated useful lives. The ranges of estimated
useful lives are generally as follows:
|
Furniture
and fixtures
|
2 to 6
years
|
|
Machinery
and equipment
|
3 to 6
years
|
|
Test
equipment
|
4 to 6
years
|
REVENUE
RECOGNITION:
The
Company recognizes revenue upon the shipment of products or the
performance of services when: (1) persuasive evidence of the
arrangement exists; (2) goods or services have been delivered; (3)
the price is fixed or determinable; and (4) collectibility is
reasonably assured. When a sales agreement involves multiple
deliverables, such as extended support provisions, training to be
supplied after delivery of the systems, and test programs specific
to customers’ routine
35
applications, the multiple deliverables are evaluated to determine
the unit of accounting. Judgment is required to properly identify
the accounting units of multiple element transactions and the
manner in which revenue is allocated among the accounting units.
Judgments made, or changes to judgments made, may significantly
affect the timing or amount of revenue
recognition.
Revenue
related to the multiple elements is allocated to each unit of
accounting using the relative selling price hierarchy. Consistent
with accounting guidance, the selling price is based upon vendor
specific objective evidence (VSOE). If VSOE is not available, third
party evidence (TPE) is used to establish the selling price. In the
absence of VSOE or TPE, estimated selling price is
used.
During
the first quarter of fiscal 2013, the Company entered into an
agreement with a customer to develop a next generation system, and
the Company shipped the first system in July 2016. The project
identifies multiple milestones with values assigned to each. The
consideration earned upon achieving the milestone is required to
meet the following conditions prior to recognition: (i) the value
is commensurate with the vendor’s performance to meet the
milestone, (ii) it relates solely to past performance, (iii) and it
is reasonable relative to all of the deliverables and payment terms
within the arrangement. Revenue is recognized for the milestone
upon acceptance by the customer.
The
Company recognizes revenue in certain circumstances before physical
delivery has occurred. In these arrangements, among other things,
risk of ownership has passed to the customer, the customer has made
a written fixed commitment to purchase the products, the customer
has requested the products be held for future delivery as scheduled
and designated by them, and no additional performance obligations
exist by the Company. For these transactions, the products are
segregated from inventory and normal billing and credit terms
granted.
Sales
tax collected from customers is not included in net sales but
rather recorded as a liability due to the respective taxing
authorities. Provisions for the estimated future cost of warranty
and installation are recorded at the time the products are
shipped.
Royalty-based
revenue related to licensing income from performance test boards
and burn-in boards is recognized upon the earlier of the receipt by
the Company of the licensee’s report related to its usage of
the licensed intellectual property or upon payment by the
licensee.
The
Company’s terms of sales with distributors are generally FOB
shipping point with payment due within 60 days. All products go
through in-house testing and verification of specifications before
shipment. Apart from warranty reserves, credits issued have not
been material as a percentage of net sales. The Company’s
distributors do not generally carry inventories of the
Company’s products. Instead, the distributors place orders
with the Company at or about the time they receive orders from
their customers. The Company’s shipment terms to our
distributors do not provide for credits or rights of return.
Because the Company’s distributors do not generally carry
inventories of our products, they do not have rights to price
protection or to return products. At the time the Company ships
products to the distributors, the price is fixed. Subsequent to the
issuance of the invoice, there are no discounts or special terms.
The Company does not give the buyer the right to return the product
or to receive future price concessions. The Company’s
arrangements do not include vendor consideration.
PRODUCT
DEVELOPMENT COSTS AND CAPITALIZED SOFTWARE:
Costs
incurred in the research and development of new products or systems
are charged to operations as incurred. Costs incurred in the
development of software programs for the Company’s products
are charged to operations as incurred until technological
feasibility of the software has been established. Generally,
technological feasibility is established when the software module
performs its primary functions described in its original
specifications, contains features required for it to be usable in a
production environment, is completely documented and the related
hardware portion of the product is complete. After technological
feasibility is established, any additional costs are capitalized.
Capitalization of software costs ceases when the software is
substantially complete and is ready for its intended use.
Capitalized costs are amortized over the estimated life of the
related software product using the greater of the units of sales or
straight-line methods over ten years. No system software
development costs were capitalized or amortized in fiscal 2018,
2017 and 2016.
IMPAIRMENT
OF LONG-LIVED ASSETS:
In
the event that facts and circumstances indicate that the carrying
value of assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated
future undiscounted cash flows associated with the asset would be
compared to the asset’s carrying value to determine if a
write-down is required.
36
ADVERTISING
COSTS:
The
Company expenses all advertising costs as incurred and the amounts
were not material for all periods presented.
SHIPPING
AND HANDLING OF PRODUCTS:
Amounts
billed to customers for shipping and handling of products are
included in net sales. Costs incurred related to shipping and
handling of products are included in cost of sales.
INCOME
TAXES:
Income
taxes have been provided using the liability method whereby
deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets and
liabilities and net operating loss and tax credit carryforwards
measured using the enacted tax rates and laws that will be in
effect when the differences are expected to reverse or the
carryforwards are utilized. Valuation allowances are established
when it is determined that it is more likely than not that such
assets will not be realized.
A
full valuation allowance was established against all deferred tax
assets, as management determined that it is more likely than not
that deferred tax assets will not be realized, as of May 31, 2018
and 2017.
The
Company accounts for uncertain tax positions consistent with
authoritative guidance. The guidance prescribes a “more
likely than not” recognition threshold and measurement
attribute for the financial statement recognition and measurement
of a tax position taken or expected to be taken in a tax return.
The Company does not expect any material change in its unrecognized
tax benefits over the next twelve months. The Company recognizes
interest and penalties related to unrecognized tax benefits as a
component of income taxes.
Although
the Company files U.S. federal, various state, and foreign tax
returns, the Company’s only major tax jurisdictions are the
United States, California, Germany and Japan. Tax years 1996
– 2017 remain subject to examination by the appropriate
governmental agencies due to tax loss carryovers, research and
development tax credits, or other tax attributes from those
years.
COMPREHENSIVE
INCOME (LOSS):
Comprehensive
income (loss) generally represents all changes in
shareholders’ equity except those resulting from investments
or contributions by shareholders. Unrealized gains and losses on
foreign currency translation adjustments are included in the
Company’s components of comprehensive income (loss), which
are excluded from net income (loss). Comprehensive income (loss) is
included in the statements of comprehensive income
(loss).
RECENT
ACCOUNTING PRONOUNCEMENTS:
Accounting
Standards Adopted
Inventory
Measurement
In
July 2015, the Financial Accounting Standards Board
(“FASB”) issued an accounting standard update that
requires management to measure inventory at the lower of cost or
net realizable value. Net realizable value is the estimated selling
prices in the ordinary course of business, less reasonably
predictable costs of completion, disposal, and transportation. The
Company adopted this new standard in fiscal year 2018. The adoption
of this guidance did not have a significant impact on the
Company’s consolidated financial statements.
Balance
Sheet Classification of Deferred Taxes
In
November 2015, the FASB issued an accounting standard update
related to deferred tax assets and liabilities. This standard
simplifies the presentation of deferred income taxes to be
classified as noncurrent in the consolidated balance sheet. The
Company adopted this new standard in fiscal year 2018. The adoption
of this guidance did not have a significant impact on the
Company’s consolidated financial statements.
Share-Based Compensation
In
March 2016, the FASB released an accounting standard update that
simplifies several aspects of the accounting for share-based
payment transactions, including the income tax consequences,
forfeitures, classification of awards as either equity or
liabilities, and classification on the statement of cash flows. The
Company adopted this new standard in fiscal year 2018. The adoption
of this guidance did not have a significant impact on the
Company’s consolidated financial statements.
37
Income Taxes
On December 22, 2017, the US government enacted comprehensive tax
legislation commonly referred to as the Tax Cuts and Jobs Act (the
“Tax Act”). The Tax Act makes broad and complex changes
to the US tax code including but not limited to (1) reducing the US
federal corporate tax rate from 34% to 21%; (2) requiring
companies to pay a one-time transition tax on certain repatriated
earnings of foreign subsidiaries; (3) generally eliminating US
federal income taxes on dividends from foreign subsidiaries; (4)
requiring a current inclusion in US federal income of certain
earnings of controlled foreign corporations; (5) creating a new
limitation on deductible interest expense; (6) changing rules
related to the uses and limitations of net operating loss
carryforwards created in tax years beginning after December 31,
2017; and (7) repeals the corporate alternative minimum tax, or
AMT, effective December 31, 2017 and repeals the corporate
alternative minimum tax regime and permits existing minimum tax
credits to offset the regular tax liability for any tax year.
Consequently, we have accounted for the reduction of $6.4 million
of deferred tax assets with an offsetting adjustment to the
valuation allowance for the fiscal year ended 2018,.and recorded a
benefit of $90,000 for our Federal refundable AMT
credit.
On
December 22, 2017, the SEC staff issued Staff Accounting Bulletin
No. 118 (“SAB 118”) which provides guidance on
accounting for the tax effects of the Tax act. SAB 118 provides a
measurement period that should not extend beyond one year from the
Tax Act enactment date for companies to complete the accounting
under ASC 740, Income taxes. In accordance with SAB 118, a company
must reflect the income tax effects of those aspects of the Tax Act
for which the accounting under ASC 740 is complete. To the extent
that a company’s accounting for certain income tax effects of
the Tax Act is incomplete but it is able to determine a reasonable
estimate, it must record and provisional estimate in the financial
statements. There are also certain transitional impacts of the Tax
Act. As part of the transition to the new territorial tax system,
the Tax Act imposes a one-time repatriation tax on deemed
repatriation of historical earnings of foreign subsidiaries. These
transitional impacts has no impact to the company for the year
fiscal year ended 2018. The one-time transition tax is based on
post-1986 earnings and profits that were previously deferred from
US income tax. While we have not yet finalized our calculation of
the total post-1986 Earnings and profits, for our foreign
corporations or the impact of foreign tax credits, we have prepared
a reasonable estimate and calculated the provision amount. The
Company is evaluating the calculation of the transition tax. The
accounting for this item is incomplete and may change as our
interpretation of the provisions of the Act evolve, additional
information becomes available or interpretive guidance is issued by
the U.S. Treasury. The final determination will be completed no
later than one year from the enactment date. Based on the current
year and carryover losses and the valuation allowance the Company
would not expect an impact to the financial statements as a result
of the completion of the analysis.
Accounting
Standards Not Yet Adopted
Revenue
Recognition
In
May 2014, the FASB issued ASC Update No. 2014-09, Revenue from
Contracts with Customers (Topic 606), which has been subsequently
updated. The new standard will supersede nearly all U.S. GAAP on
revenue recognition and eliminate industry-specific guidance. The
core principle of the standard is to recognize revenues when
promised goods or services are transferred to customers in an
amount that reflects the consideration that is expected to be
received for those goods or services. The new standard defines a
five-step process to achieve this core principle and, in doing so,
it is possible more judgment and estimates may be required within
the revenue recognition process than required under existing GAAP,
including identifying performance obligations in the contract,
estimating the amount of variable consideration to include in the
transaction price, and allocating the transaction price to each
distinct performance obligation. It also requires increased
disclosures including the nature, amount, timing, and uncertainty
of revenues and cash flows related to contracts with customers. The
new guidance will become effective for the Company in the first
quarter of fiscal 2019, which is the Company’s planned
adoption date.
The
standard allows two methods of adoption: i) retrospectively to each
prior period presented (“full retrospective method”),
or ii) retrospectively with the cumulative effect recognized in
retained earnings as of the date of adoption ("modified
retrospective method").
The
Company plans to adopt Topic 606 using the modified retrospective
method through a cumulative effect adjustment being recognized in
accumulated deficit as of the adoption date. Under that method, the
Company will not restate the prior financial statements but apply
the rules to contracts that are complete or incomplete as of June
1, 2018 and recognize the cumulative effect of initially applying
the new standard as an adjustment to the opening balance of
accumulative deficit.
The
Company has reached conclusions on its accounting assessments
related to the standard and does not expect to record an adjustment
to the opening cumulative deficits as the impact deems
insignificant.
The
adoption of the new standard will not significantly impact the
Company’s process, procedure and control. The Company is
currently in the process of developing, implementing and testing
its internal systems, processes and controls
38
necessary
to adopt Topic 606, and is in process of making the necessary
changes to its accounting policies. In addition, the Company is
currently evaluating the impact of the expanded disclosures to its
consolidated financial statements.
Financial
Instruments
In
January 2016, the FASB issued an accounting standard update related
to recognition and measurement of financial assets and financial
liabilities. This standard changes accounting for equity
investments, financial liabilities under the fair value option and
the presentation and disclosure requirements for financial
instruments. In addition, it clarifies guidance related to the
valuation allowance assessment when recognizing deferred tax assets
resulting from unrealized losses on available-for-sale debt
securities. This standard is effective for us in fiscal year 2020.
Early adoption is permitted. The Company is currently evaluating
the impact of this new guidance on its consolidated financial
statements.
In
June 2016, the FASB issued an accounting standard update that
requires measurement and recognition of expected credit losses for
financial assets held based on historical experience, current
conditions, and reasonable and supportable forecasts that affect
the collectibility of the reported amount. The accounting standard
update will be effective for the Company beginning in the first
quarter of fiscal 2021 on a modified retrospective basis, and early
adoption in fiscal 2020 is permitted. The Company is currently
evaluating the impact of this accounting standard update on its
consolidated financial statements.
Leases
In
February 2016, the FASB issued authoritative guidance related to
leases. This guidance requires management to present all leases
greater than one year on the balance sheet as a liability to make
payments and an asset as the right to use the underlying asset for
the lease term. This new standard will be effective for us in
fiscal year 2020, with early adoption permitted. The Company is
currently evaluating the impact of adopting this new guidance on
its consolidated financial statements.
Classification
of Certain Cash Receipts and Cash Payments
In
August 2016, the FASB issued authoritative guidance related to the
classification of certain cash receipts and cash payments on the
statement of cash flows. The accounting standard update will be
effective for the Company beginning in the first quarter of fiscal
2019 on a retrospective basis, and early adoption is permitted. The
Company is currently evaluating the impact of this accounting
standard update on its consolidated statements of cash
flows.
Intra-Entity
Asset Transfers
In
October 2016, the FASB issued an accounting standard update that
requires recognition of the income tax consequences of intra-entity
transfers of assets (other than inventory) at the transaction date.
The accounting standard update will be effective for the Company
beginning in the first quarter of fiscal 2019 on a modified
retrospective basis, and early adoption is permitted. The Company
is currently evaluating the impact of this accounting standard
update on its consolidated financial statements.
Restricted
Cash
In
November 2016, the FASB issued authoritative guidance related to
statements of cash flows. This guidance clarifies that amounts
generally described as restricted cash and restricted cash
equivalents should be included with cash and cash equivalents when
reconciling the beginning-of-period and end-of period total amounts
shown on the statement of cash flows. The accounting standard
update will be effective for the Company beginning in the first
quarter of fiscal 2019 on a retrospective basis, and early adoption
is permitted. The Company is currently evaluating the impact of
this accounting standard update on its consolidated financial
statements.
2. EARNINGS PER SHARE (“EPS”):
Basic
EPS is determined using the weighted average number of common
shares outstanding during the period. Diluted EPS is determined
using the weighted average number of common shares and potential
common shares (representing the dilutive effect of stock options,
RSUs and ESPP shares) outstanding during the period using the
treasury stock method.
The
following table presents the computation of basic and diluted net
income (loss) per share attributable to Aehr Test Systems common
shareholders (in thousands, except per share data):

For
the purpose of computing diluted earnings per share, the weighted
average number of potential common shares does not include stock
options with an exercise price greater than the average fair value
of the Company’s common stock for the period, as the effect
would be anti-dilutive. Stock options to purchase 1,313,000 shares
of common stock were outstanding as of May 31, 2018 but were not
included in the computation of diluted net income per share,
because the inclusion of such shares would be anti-dilutive. In the
fiscal year ended May 31, 2017 and 2016, potential common shares
have not been included in the calculation of diluted net loss per
share as the effect would be anti-dilutive. As such, the numerator
and the denominator used in computing both basic and diluted net
loss per share for these periods are the same. Stock options to
purchase 3,074,000 and 3,201,000 shares of common stock were
outstanding on May 31, 2017 and 2016, respectively, but were not
included in the computation of diluted net loss per share, because
the inclusion of such shares would be anti-dilutive. ESPP rights to
purchase 169,000 and 304,000 ESPP shares were outstanding on May
31, 2017 and 2016, respectively, but were not included in the
computation of diluted net loss per share, because the inclusion of
such shares would be anti-dilutive. RSUs for 32,000 shares and 0
shares were outstanding on May 31, 2017 and 2016, respectively, but
were not included in the computation of diluted net loss per share,
because the inclusion of such shares would be anti-dilutive. The
2,657,000 shares convertible under the convertible notes
outstanding on May 31, 2018, 2017 and 2016 were not included in the
computation of diluted net income (loss) per share, because the
inclusion of such shares would be anti-dilutive.

4. FAIR VALUE MEASUREMENT:
The
Company’s financial instruments are measured at fair value
consistent with authoritative guidance. This authoritative guidance
defines fair value, establishes a framework for using fair value to
measure assets and liabilities, and disclosures required related to
fair value measurements.
The
guidance establishes a fair value hierarchy based on inputs to
valuation techniques that are used to measure fair value that are
either observable or unobservable. Observable inputs reflect
assumptions market participants would use in pricing an asset or
liability based on market data obtained from independent sources
while unobservable inputs reflect a reporting entity’s
pricing based upon their own market assumptions. The fair value
hierarchy consists of the following three levels:
Level 1
- instrument valuations are obtained from real-time quotes for
transactions in active exchange markets involving identical
assets.
Level 2
- instrument valuations are obtained from readily-available pricing
sources for comparable instruments.
Level 3
- instrument valuations are obtained without observable market
values and require a high level of judgment to determine the fair
value.

following table summarizes the Company’s financial assets
measured at fair value on a recurring basis as of May 31, 2018 (in
thousands):

There
were no transfers between Level 1 and Level 2 fair value
measurements during the fiscal year ended May 31, 2018 and
2017.
The
carrying amounts of financial instruments including cash, cash
equivalents, receivables, accounts payable and certain other
accrued liabilities, approximate fair value due to their short
maturities. Based on the borrowing rates currently available to the
Company for loans with similar terms, the carrying value of the
debt approximates the fair value.
The
Company has at times invested in debt and equity of private
companies, and may do so again in the future, as part of its
business strategy.

The
valuation allowance decreased by $6,139,000 during fiscal 2018,
increased by $1,635,000 during fiscal 2017, and increased by
$421,000 during fiscal 2016. As of May 31, 2018 and 2017, the
Company concluded that it is more likely than not that the deferred
tax assets will not be realized and therefore provided a full
valuation allowance against the deferred tax assets. The Company
will continue to evaluate the need for a valuation allowance
against its deferred tax assets on a quarterly basis.
At
May 31, 2018, the Company had federal and state net operating loss
carryforwards of $50,356,000 and $31,340,000 respectively. The
federal and state net operating loss carryforwards will begin to
expire in 2024. At May 31, 2018, the Company also had federal and
state research and development tax credit carryforwards of
$2,157,000 and $5,428,000, respectively. The federal credit
carryforward will begin to expire in 2019, and the California
credit will carryforward indefinitely. These carryforwards may be
subject to certain limitations on annual utilization in case of a
change in ownership, as defined by tax law. The Company also has
alternative minimum tax credit carryforwards of $34,000 for state
purposes. The credits may be used to offset regular tax and do not
expire.
The
Company has made no provision for U.S. income taxes on
undistributed earnings of certain foreign subsidiaries because it
is the Company’s intention to permanently reinvest such
earnings in its foreign subsidiaries. If such earnings were
distributed, the Company would be subject to additional U.S. income
tax expense. Determination of the amount of unrecognized deferred
income tax liability related to these earnings is not
practicable.
Foreign
net operating loss carryforwards of $457,000 are available to
reduce future foreign taxable income. The foreign net operating
losses will expire starting fiscal year 2019.
The
Company maintains liabilities for uncertain tax positions. These
liabilities involve considerable judgment and estimation and are
continuously monitored by management based on the best information
available. The aggregate changes in the balance of gross
unrecognized tax benefits are as follows (in

The
ending balance of $1,785,000 of unrecognized tax benefits as of May
31, 2018, if recognized, would not impact the effective tax
rate.
On
December 22, 2017, the U.S. government enacted comprehensive tax
legislation commonly referred to as the Tax Cuts and Jobs Act (the
“Tax Act”). On December 22, 2017, the SEC staff issued
Staff Accounting Bulletin No. 118 (“SAB 118”), which
provides guidance on accounting for the tax effects of the Tax Act.
SAB 118 provides a measurement period that should not extend beyond
one year from the Tax Act enactment date for companies to complete
the accounting under ASC 740, Income taxes. In accordance with SAB
118, a company must reflect the income tax effects of those aspects
of the Tax Act for which the accounting under ASC 740 is complete.
To the extent that a company’s accounting for certain income
tax effects of the Tax Act is incomplete but it is able to
determine a reasonable estimate, it must record a provisional
estimate in the financial statements.
As
part of the transition to the new territorial tax system, the Tax
Act imposes a one-time repatriation tax on deemed repatriation of
historical earnings of foreign subsidiaries. The company is not
subject to the transition tax. The one-time transition tax is based
on post-1986 earnings and profits that were previously deferred
from U.S. income tax. While the Company has not yet finalized its
calculation of the total post-1986 earnings and profits for its
foreign corporations or the impact of foreign tax credits, it has
prepared a reasonable estimate and calculation of nil transition
tax. The Company is continuing to evaluate the calculation and
accounting of the transition tax, which may change as the Company's
interpretation of the provisions of the Tax Act evolve, additional
information becomes available or interpretive guidance is issued by
the U.S. Treasury. The final determination will be completed no
later than one year from the enactment date. Based on current year
and carryover losses and valuation allowance, the Company does not
expect an impact to its consolidated financial statements upon
completion of the analysis.
The
new law also repeals the corporate alternative minimum tax, or AMT,
effective December 31, 2017. The law repeals the corporate
alternative minimum tax regime and permits existing minimum tax
credits to offset the regular tax liability for any tax year.
Further, the credit is refundable for any tax year beginning after
December 31, 2017 and before December 31, 2020 in an amount equal
to 50% of the excess of the minimum tax credit over the allowable
credit for the year against the regular tax liability. Any unused
minimum tax credit carryforward is refundable in the following
year. As result, the company recorded a benefit of $90,000 for its
Federal refundable AMT credit.
In
addition, the reduction of U.S. federal corporate tax rate reduces
the corporate tax rate to 21%, effective January 1, 2018.
Consequently, the Company has accounted for the reduction of $6.4
million of deferred tax assets with an offsetting adjustment to the
valuation allowance.
Although
the Company files U.S. federal, various state, and foreign tax
returns, the Company’s only major tax jurisdictions are the
United States, California, Germany and Japan. Tax years 1996
– 2017 remain subject to examination by the appropriate
governmental agencies due to tax loss carryovers, research and
development tax credits, or other tax attributes from those
years.
On
April 10, 2015, the Company entered into a Convertible Note
Purchase and Credit Facility Agreement (the “Purchase
Agreement”) with QVT Fund LP and Quintessence Fund L.P. (the
“Purchasers”) providing for (a) the Company’s
sale to the Purchasers of $4,110,000 in aggregate principal amount
of 9.0% Convertible Secured Notes due
2017 (the
“Convertible Notes”) and (b) a secured revolving loan
facility (the “Credit Facility”) in an aggregate
principal
amount of up to
$2,000,000. On August 22, 2016 the Purchase Agreement was amended
to extend the maturity date of
45
the
Convertible Notes to April 10, 2019, decrease the conversion price
from $2.65 per share to $2.30 per share, decrease the forced
conversion price from $7.50 per share to $6.51 per share, and allow
for additional equity awards.
The
Convertible Notes bear interest at an annual rate of 9.0% and will
mature on April 10, 2019 unless repurchased or converted prior to
that date. Interest is payable quarterly on March 1, June 1,
September 1 and December 1 of each year. Debt issuance costs of
$356,000, which were accreted over the term of the original loan
using the effective interest rate method, were offset against the
loan balance.
The
conversion price for the Convertible Notes is $2.30 per share and
is subject to adjustment upon the occurrence of certain specified
events. Holders may convert all or any part of the principal amount
of their Convertible Notes in integrals of $10,000 at any time
prior to the maturity date. Upon conversion, the Company will
deliver shares of its common stock to the holder of Convertible
Notes electing such conversion. The Company may not redeem the
Convertible Notes prior to maturity.
The
maximum amount of $2,000,000 drawn against the Credit Facility has
been converted to Convertible Notes, and at May 31, 2018 there was
no remaining balance available to be drawn on the Credit
Facility.
The
Company’s obligations under the Purchase Agreement are
secured by substantially all of the assets of the
Company.
9. EQUITY:
On August 8, 2016 the Company issued
200,000 shares of its common stock to Semics Inc., a semiconductor
test equipment provider that produces fully automatic wafer probe
systems, in consideration for cancellation of an outstanding
invoice of $323,000 for capital equipment.
On
September 28, 2016, the Company sold 2,722,000 shares of its common
stock in a private placement transaction to certain institutional
and accredited investors. The purchase price per share of the
common stock sold in the private placement was $2.15, resulting in
gross proceeds to the Company of $5,851,000, before offering
expenses. The net proceeds after offering expenses were
$5,299,000.
On
April 19 2017, the Company completed a public offering of 4,423,000
shares of its common stock at a price to the public of $3.90 per
share, including the underwriter’s exercise of its option to
purchase 577,000 additional shares to cover over-allotments. The
gross proceeds to the Company were $17,250,000, before underwriting
discounts and offering expenses. The net proceeds after
underwriting discounts and offering expenses were
$15,832,000.

STOCK-BASED
COMPENSATION:
Stock-based
compensation expense consists of expenses for stock options,
restricted stock units, or RSUs, and employee stock purchase plan,
or ESPP, purchase rights. Stock-based compensation expense for
stock options and ESPP purchase rights is measured at each grant
date, based on the fair value of the award using the Black-Scholes
option valuation model, and is recognized as expense over the
employee’s requisite service period. This model was developed
for use in estimating the value of publicly traded options that
have no vesting restrictions and are fully transferable. The
Company’s employee stock options have characteristics
significantly different from those of publicly traded options. For
RSUs, stock-based compensation expense is based on the fair value
of the Company’s common stock at the grant date. All of the
Company’s stock-based compensation is accounted for as equity
instruments.
The
following table summarizes the stock-based compensation expense for
the years ended May 31, 2018, 2017 and 2016 (in thousands, except

As
of May 31, 2018, 2017 and 2016, there were no stock-based
compensation expenses capitalized as part of
inventory.
During
fiscal 2018, 2017 and fiscal 2016, the Company recorded stock-based
compensation related to stock options and restricted stock units of
$706,000, $884,000 and $894,000, respectively.
As
of May 31, 2018, the total compensation expense related to unvested
stock-based awards under the Company’s 2016 Equity Incentive
Plan, but not yet recognized, was $976,000 which is net of
estimated forfeitures of $2,000. This expense will be amortized on
a straight-line basis over a weighted average period of
approximately 2.5 years.
During
fiscal 2018, 2017 and fiscal 2016, the Company recorded stock-based
compensation related to its ESPP of $290,000, $115,000 and
$122,000, respectively. The increase in fiscal 2018 is primarily
due to employees increasing their ESPP elections during the fiscal
year.
As
of May 31, 2018, the total compensation expense related to purchase
rights under the ESPP but not yet recognized was $306,000. This
expense will be amortized on a straight-line basis over a weighted
average period of approximately 1.3 years.
Valuation
Assumptions
Valuation
and Amortization Method. The Company estimates the fair value of
stock options granted using the Black-Scholes option valuation
method and a single option award approach. The fair value under the
single option approach is amortized on a straight-line basis over
the requisite service periods of the awards, which is generally the
vesting period.
Expected
Term. The Company’s expected term represents the period that
the Company’s stock-based awards are expected to be
outstanding and was determined based on historical experience,
giving consideration to the contractual terms of the stock-based
awards, vesting schedules and expectations of future employee
behavior as evidenced by changes to the terms of its stock-based
awards.
Volatility.
Volatility is a measure of the amounts by which a financial
variable such as stock price has fluctuated (historical volatility)
or is expected to fluctuate (expected volatility) during a period.
The Company uses the historical volatility for the past five years,
which matches the expected term of most of the option grants, to
estimate expected volatility. Volatility for each of the
ESPP’s four time periods of six months, twelve months,
eighteen months, and twenty-four months is calculated separately
and included in the overall stock-based compensation expense
recorded.
47
Risk-Free
Interest Rate. The Company bases the risk-free interest rate used
in the Black-Scholes option valuation method on the implied yield
in effect at the time of option grant on U.S. Treasury zero-coupon
issues with a remaining term equivalent to the expected term of the
stock awards including the ESPP.
Fair
Value. The fair values of the Company’s stock options granted
to employees in fiscal 2018, 2017 and 2016 were estimated using the
following weighted average assumptions in the Black-Scholes option
valuation method:

EQUITY
INCENTIVE PLAN:
In
October 2006, the Company’s 2006 Equity Incentive Plan was
approved by the shareholders, which provides for granting of
incentive stock options, nonstatutory stock options, restricted
stock, restricted stock units, stock appreciation rights,
performance units, performance shares and other stock or cash
awards as the Company’s Board of Directors may
determine.
In
October 2016, the Company’s 2016 Equity Incentive Plan was
approved by the Company’s shareholders. The 2016 Equity
Incentive Plan replaced our 2006 Equity Incentive Plan, which was
scheduled to expire in October 2016, and will continue in effect
until 2026. A total of 2,238,000 shares of common stock have been
reserved for issuance under the Company’s 2016 Equity
Incentive Plan, which includes 1,438,000 shares that remained
available for issuance under the 2006 Equity Incentive Plan. See
the Company’s Registration Statement on Form S-8 filed with
the Securities and Exchange Commission on November 14, 2016 for
further information regarding the 2016 Equity Incentive
Plan.
As of May 31, 2018,
out of the 4,718,000 shares authorized for grant under the 2016
Equity Incentive Plan, 2,906,000 stock options and RSUs were
outstanding. As of May 31, 2017, out of the 5,275,000 shares
authorized for grant under the 2006 Equity Incentive Plan and 2016
Equity Incentive Plan, 3,105,000 stock options and RSUs were
outstanding.

EMPLOYEE
STOCK PURCHASE PLAN:
In
October 2006, the Company’s shareholders approved the 2006
Employee Stock Purchase Plan. In October 2016, the Company’s
Amended and Restated 2006 Employee Stock Purchase Plan, or Purchase
Plan, was approved by the Company’s shareholders. The
Purchase Plan extended the term of the 2006 Employee Stock Purchase
Plan indefinitely. A total of 532,000 shares of the Company’s
common stock were reserved for issuance under the Purchase Plan.
See the Company’s Registration Statement on Form S-8 filed
with the Securities and Exchange Commission on November 14, 2016
for further information regarding the Purchase Plan. The Purchase
Plan has consecutive, overlapping, twenty-four month offering
periods. Each twenty-four month offering period includes four six
month purchase periods. The offering periods generally begin on the
first trading day on or after April 1 and October 1 each year. All
employees who work a minimum of 20 hours per week and are
customarily employed by the Company (or an affiliate thereof) for
at least five months per calendar year are eligible to participate.
Under the Purchase Plan, shares are purchased through employee
payroll deductions at exercise prices equal to 85% of the lesser of
the fair market value of the Company’s common stock at either
the first day of an offering period or the last day of the purchase
period. If a participant’s rights to purchase stock under all
employee stock purchase plans of the Company accrue at a rate which
exceeds $25,000 worth of stock for a calendar year, such
participant may not be granted an option to purchase stock under
the Purchase Plan. The maximum number of shares a participant may
purchase during a single purchase period is 3,000 shares. During
the fiscal years ended May 31, 2018, 2017 and 2016, ESPP purchase
rights of 359,000, 1,000, and 304,000 shares, respectively, were
granted. For the years ended May 31, 2018, 2017 and 2016,
approximately 237,000, 151,000 and
50
86,000
shares of common stock, respectively, were issued under the plans.
As of May 31, 2018, 1,355,000 shares have been issued under the
ESPP, and there were 145,000 ESPP shares available for
issuance.
11. EMPLOYEE BENEFIT PLANS:
EMPLOYEE
STOCK OWNERSHIP PLAN:
The
Company has a non-contributory, trusteed employee stock ownership
plan for full-time employees who have completed three consecutive
months of service and for part-time employees who have completed
one year of service and have attained an age of 21. The Company can
contribute either shares of the Company’s stock or cash to
the plan. The contribution is determined annually by the Company
and cannot exceed 15% of the annual aggregate salaries of those
employees eligible for participation in the plan. On May 31, 2007,
the Company converted the Aehr Test Systems Employee Stock Bonus
Plan into the Aehr Test Systems Employee Stock Ownership Plan (the
“Plan”). The stock bonus plan was converted to an
employee stock ownership plan (“ESOP”) to enable the
Plan to better comply with changes in the law regarding Company
stock. Individuals’ account balances vest at a rate of 20%
per year commencing upon completion of two years of service.
Non-vested balances, which are forfeited following termination of
employment, are allocated to the remaining employees in the Plan.
Under the Plan provisions, each employee who reaches age fifty-five
(55) and has been a participant in the Plan for ten years will be
offered an election each year to direct the transfer of up to 25%
of his/her ESOP account to the employee self-directed account in
the Savings and Retirement Plan. For anyone who met the above
prerequisites, the first election to diversify holdings was offered
after May 31, 2008. In the sixth year, employees will be able to
diversify up to 50% of their ESOP accounts. Contributions of
$60,000 per year were authorized for the plan during fiscal 2018,
2017 and 2016. The contribution amounts are recorded as
compensation expense, in the period authorized and included in
accrued expenses, in the period authorized. Contributions of 13,000
shares were made to the ESOP during fiscal 2018 for fiscal 2017.
Contributions of 59,000 shares were made to the ESOP during fiscal
2017 for fiscal 2016. Contributions of 25,000 shares were made to
the ESOP during fiscal 2016 for fiscal 2015. The contribution for
fiscal 2018 will be made in fiscal 2019. Shares held in the ESOP
are included in the EPS calculation.
401(K)
PLAN:
The
Company maintains a defined contribution savings plan (the
“401(k) Plan”) to provide retirement income to all
qualified employees of the Company. The 401(k) Plan is intended to
be qualified under Section 401(k) of the Internal Revenue Code of
1986, as amended. The 401(k) Plan is funded by voluntary pre-tax
contributions from employees. Contributions are invested, as
directed by the participant, in investment funds available under
the 401(k) Plan. The Company is not required to make, and did not
make, any contributions to the 401(k) Plan during fiscal 2018, 2017
and 2016.

13. PRODUCT WARRANTIES:
The
Company provides for the estimated cost of product warranties at
the time revenues are recognized on the products shipped. While the
Company engages in extensive product quality programs and
processes, including actively monitoring and evaluating the quality
of its component suppliers, the Company’s warranty obligation
is affected by product failure rates, material usage and service
delivery costs incurred in correcting a product failure. Should
actual product failure rates, material usage or service delivery
costs differ from the Company’s estimates, revisions to the
estimated warranty liability would be required.
The
standard warranty period is one year for systems and ninety days
for parts and service.

16. COMMITMENTS AND CONTINGENCIES:
COMMITMENTS
The
Company leases most of its manufacturing and office space under
operating leases. The Company entered into non-cancelable operating
lease agreements for its United States manufacturing and office
facilities and maintains equipment under non-cancelable operating
leases in Germany. The Company’s principal administrative and
production facilities are located in Fremont, California, in a
51,289 square foot building. The Company’s lease was renewed
in February 2018 and expires in July 2023. The Company’s
facility in Japan is located in a 418 square foot office in Tokyo
under a cancellable lease which expires in June 2019. The Company
also maintains a 1,585 square foot warehouse in Yamanashi under a
lease which expires in November 2019. The Company leases a 492
square foot sales and support office in Utting, Germany. The lease,
which began February 1, 1992 and expires on January 31, 2020,

expense for the years ended May 31, 2018, 2017 and 2016 was
$587,000, $509,000 and $499,000, respectively.
At
May 31, 2018 and 2017, the Company had a $80,000 and $50,000,
respectively, certificate of deposit held by a financial
institution representing a security deposit for its United States
manufacturing and office space lease. This amount is included in
other assets on the consolidated balance sheets.
PURCHASE
OBLIGATIONS
The
Company has purchase obligations to certain suppliers. In some
cases the products the Company purchases are unique and have
provisions against cancellation of the order. At May 31, 2018, the
Company had $2,488,000 of purchase obligations which are due within
the following 12 months. This amount does not include contractual
obligations recorded on the consolidated balance sheets as
liabilities.
CONTINGENCIES
The
Company may, from time to time, be involved in legal proceedings
arising in the ordinary course of business. While there can be no
assurances as to the ultimate outcome of any litigation involving
the Company, management does not believe any pending legal
proceedings will result in judgment or settlement that will have a
material adverse effect on the Company’s consolidated
financial position, results of operations or cash
flows.
In
the normal course of business to facilitate sales of its products,
the Company indemnifies other parties, including customers, with
respect to certain matters, for example, including against losses
arising from a breach of representations or covenants, or from
intellectual property infringement or other claims. These
agreements may limit the time within which an indemnification claim
can be made and the amount of the claim. In addition, the Company
has entered into indemnification agreements with its officers and
directors, and the Company’s bylaws contain similar
indemnification obligations to the Company’s
agents.
It
is not possible to determine the maximum potential amount under
these indemnification agreements due to the limited history of
prior indemnification claims and the unique facts and circumstances
involved in each particular agreement. To date, payments made by
the Company under these agreements have not had a material impact
on the Company’s operating results, financial position or
cash flows.
17. SELECTED QUARTERLY CONSOLIDATED FINANCIAL DATA

(a)
Evaluation of disclosure controls and
procedures.
Our
management evaluated, with the participation of our Chief Executive
Officer and Chief Financial Officer, the effectiveness of our
disclosure controls and procedures, as defined in Rules 13a-15(e)
and 15d-15(e) under the Exchange Act, as of the end of the period
covered by this Annual Report on Form 10-K. Based on this
evaluation, our Chief Executive Officer and our Chief Financial
Officer have concluded that our disclosure controls and procedures
are effective to ensure that information we are required to
disclose in reports that we file or submit under the Securities
Exchange Act of 1934 is recorded, processed, summarized and
reported within the time periods specified in Securities and
Exchange Commission rules and forms, and that such information is
accumulated and communicated to management, including our Chief
Executive Officer and Chief Financial Officer, as appropriate to
allow for timely decisions regarding required
disclosure.
(b)
Management’s report on internal control
over financial reporting.
Our
management is responsible for establishing and maintaining adequate
internal control over financial reporting as defined in Rule
13a-15(f) of the Exchange Act. Under the supervision and with the
participation of our Chief Executive Officer and Chief Financial
Officer, our management conducted an evaluation of the
effectiveness of our internal control over financial reporting
based upon the framework in “
Internal Control – Integrated
Framework”
(2013 Framework) issued by the Committee of
Sponsoring Organizations of the Treadway Commission. Based on that
evaluation, management has concluded that the Company’s
internal control over financial reporting was effective as of May
31, 2018. This annual report does not include an attestation report
of the Company’s registered public accounting firm regarding
internal control over financial reporting. Management’s
report was not subject to attestation by the Company’s
registered public accounting firm pursuant to rules of the
Securities and Exchange Commission that permit the Company to
provide only management’s report in this Annual
Report.
(c)
Changes in internal controls over financial
reporting.
There
were no changes in our internal controls over financial reporting
that occurred during the period covered by this Annual Report on
Form 10-K that have materially affected, or are reasonably likely
to materially affect, our internal controls over financial
reporting.
None.
