NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Condensed Consolidated Financial Statements

The financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for quarterly reports on Form 10-Q and should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended December 31, 2018, included in the 2018 Annual Report on Form 10-K. All terms used but not defined elsewhere herein have the meaning ascribed to them in the Company’s 2018 Annual Report on Form 10-K filed on March 5, 2019. In the opinion of management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair presentation of the results of the interim periods have been included. The 2018 year-end condensed consolidated balance sheet data were derived from the audited financial statements but do not include all disclosures required by U.S. GAAP. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the full year.

2. Summary of Significant Accounting Policies

Adoption of ASC 842

On January 1, 2019, the Company adopted ASC 842, Leases (“ASC 842”) using the modified retrospective approach as of the effective date of the standard without revising prior periods. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward its historical lease classification. In addition, the Company elected the hindsight practical expedient to determine the lease term for existing leases. The Company’s election of the hindsight practical expedient resulted in the extension of the Oregon lease term as it was determined that the first renewal option under this lease was expected to be exercised with a reasonable degree of certainty. In the second quarter of 2019, the Company exercised the first renewal option under the Oregon lease.

The Company was required to record an operating lease right-of-use asset and a corresponding operating lease liability, equal to the present value of the lease payments at the adoption date. In the determination of future lease payments, the Company has elected to aggregate lease components such as payments for rent, taxes and insurance costs with non-lease components such as maintenance costs and account for these payments as a single lease component. The present value of the lease payments was determined using the Company's incremental borrowing rate. The impact of adopting ASC 842 as of January 1, 2019 was the recording of operating lease right-of-use assets of approximately $2.9 million ; the recording of operating lease liabilities of approximately $3.3 million ; and a decrease to deferred rent of approximately $0.4 million .

Revenue Recognition

All of the Company’s revenue is derived from long-term contracts that span multiple years. The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). A contract’s transaction price is allocated to distinct performance obligations and recognized as revenue when, or as, a performance obligation is satisfied. As of June 30, 2019, the Company's active performance obligations, for the contracts outlined in Note 3 , consist of the following: four performance obligations relate to research and development services; two relate to manufacture and delivery of product; and one is associated with storage of product. The aggregate amount of transaction price allocated to remaining performance obligations for the 2011 BARDA Contract, 2018 BARDA Contract and the IV Formulation R&D Contract was $59.2 million as of June 30, 2019. Remaining performance obligations represent the transaction price for which work has not been performed and excludes unexercised contract options.

During the three and six months ended June 30, 2019, the Company recognized a cumulative catch-up adjustment to revenue of approximately $3.3 million related to the conclusion of historical rate reconciliations in connection with the IV Formulation R&D Contract (defined in Note 3 ), and changes in the projected amount of contract funding expected to be available under the IV Formulation R&D Contract, which impacts the progress-towards-completion calculation required under ASC 606.

Contract Balances

The timing of revenue recognition, billings and cash collections may result in billed accounts receivable, unbilled receivables (contract assets) and customer advances and deposits (contract liabilities) in the condensed consolidated balance sheets. Generally, amounts are billed as work progresses in accordance with agreed-upon contractual terms either at periodic intervals (monthly) or upon achievement of contractual milestones. Under typical payment terms of fixed price arrangements, the customer pays the Company either performance-based payments or progress payments. For the Company’s cost-type arrangements, the customer

Table of Contents

generally pays the Company for its actual costs incurred, as well as its allocated overhead and G&A costs. Such payments occur within a short period of time. When the Company receives consideration, or such consideration is unconditionally due, prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. During the six months ended June 30, 2019, the Company recognized revenue of $0.5 million that was included in deferred revenue at the beginning of the period.

Restricted Cash and Cash Equivalents

Under the terms of the Loan Agreement (as defined below), net cash proceeds from the Company's Priority Review Voucher ("PRV") sale on October 31, 2018 are restricted and are held in a reserve account. Cash held in the reserve account is available to pay interest, fees and principal related to the Term Loan. See Note 8 for additional information. Prior to the second quarter of 2019, there was also a reserve account for certain proceeds of the Loan Agreement. This account was also restricted. Amounts in this reserve account were primarily used to pay interest on the Loan Agreement. This reserve account was closed in the second quarter 2019.

The following tables reconcile cash, cash equivalents and restricted cash per the condensed consolidated statements of cash flows to the condensed consolidated balance sheet for each respective period:

Recent Accounting Pronouncements

On January 26, 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. The revised guidance will be applied prospectively, and is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for any impairment tests performed after January 1, 2017. The Company believes the adoption of ASU No. 2017-04 will not have a significant impact on its consolidated financial statements.

3. Procurement Contracts and Research Agreements

2018 BARDA Contract

Table of Contents

The period of performance for options is up to ten years from the date of entry into the 2018 BARDA Contract and such options could be exercised at any time during the contract term, including during the base period of performance. On May 20, 2019, an option for the manufacture and delivery of 363,070 courses of oral TPOXX® was modified to divide it into four procurement-related options. One of the four new procurement-related options provides for the payment of $11.2 million for the procurement of raw materials to be used in the manufacture of at least 363,070 courses of oral TPOXX®. This new option was exercised simultaneously with the aforementioned modification. Each of the other three new options individually specifies the delivery of approximately 121,000 courses of oral TPOXX® for consideration of approximately $34.0 million . In total, the four new options provide for the manufacture and delivery of 363,070 courses of oral TPOXX® for consideration of approximately $112.5 million . The option modification did not change the overall total potential value of the 2018 BARDA Contract, nor did it change the total amount to be paid in connection with the manufacture and delivery of oral TPOXX® courses.

The base period of performance provides for potential payments of approximately $51.7 million for the following activities: payments of approximately $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile; payments of $8.0 million for the manufacture of 20,000 courses of final drug product of IV TPOXX® ("IV FDP"), of which $3.2 million of payments are related to the manufacture of bulk drug substance ("IV BDS") to be used in the manufacture of IV FDP; payments of approximately $32.0 million to fund advanced development of IV TPOXX®; and payments of approximately $0.6 million for supportive procurement activities. As of June 30, 2019, the Company had received $7.1 million for the first quarter 2019 delivery of approximately 23,000 courses of oral TPOXX® to the Strategic Stockpile and $3.2 million for the manufacture of IV BDS. IV BDS is expected to be used for the manufacture of 20,000 courses of IV FDP. The $3.2 million received in 2018 for the manufacture of IV BDS has been recorded as deferred revenue as of December 31, 2018 and June 30, 2019.

The options that have been exercised to date provide for potential payments up to approximately $23.4 million . There are exercised options for the following activities: payments up to $11.2 million for the procurement of raw materials to be used in the manufacture of at least 363,070 courses of oral TPOXX®; and, payments of up to $12.2 million for funding of post-marketing activities for oral TPOXX®.

Unexercised options provide for potential payments up to approximately $525.0 million in total (if all such options are exercised). There are options for the following activities: payments of up to $439.0 million for the delivery of up to approximately 1,452,300 courses of oral TPOXX® to the Strategic Stockpile; payments of up to $76.8 million for the manufacture of up to 192,000 courses of IV FDP, of which up to $30.7 million of payments would be paid upon the manufacture of IV BDS to be used in the manufacture of IV FDP; payments of up to approximately $3.6 million to fund post-marketing activities for IV TPOXX®; and payments of up to approximately $5.6 million for supportive procurement activities.

The options related to IV TPOXX® are divided into two primary manufacturing steps. There are options related to the manufacture of bulk drug substance (“IV BDS Options”), and there are corresponding options (for the same number of IV courses) for the manufacture of final drug product (“IV FDP Options”). BARDA may choose to exercise any, all, or none of these options in its sole discretion. The 2018 BARDA Contract includes: three separate IV BDS Options, each providing for the bulk drug substance equivalent of 64,000 courses of IV TPOXX®; and three separate IV FDP Options, each providing for 64,000 courses of final drug product of IV TPOXX®. BARDA has the sole discretion on whether to simultaneously exercise IV BDS Options and IV FDP Options, or whether to make independent exercise decisions. If BARDA decides to only exercise IV BDS Options, then the Company would receive payments up to $30.7 million ; alternatively, if BARDA decides to exercise both IV BDS Options and IV FDP Options, then the Company would receive payments up to $76.8 million . For each set of options relating to a specific group of courses (for instance, the IV BDS and IV FDP options that reference the same 64,000 courses), BARDA has the option to independently purchase IV BDS or IV FDP.

2011 BARDA Contract

On May 13, 2011, the Company signed a contract with BARDA pursuant to which BARDA agreed to buy from the Company 1.7 million courses of oral TPOXX®. Additionally, the Company agreed to contribute to BARDA 300,000 courses at no additional cost to BARDA.

The contract with BARDA (as amended, modified, or supplemented from time to time, the “2011 BARDA Contract”) includes a base contract, as modified, (“2011 Base Contract”) as well as options. The 2011 Base Contract provides for approximately $508.7 million of payments, of which as of June 30, 2019, $459.8 million had been received by the Company for the manufacture and delivery of 1.7 million courses of oral TPOXX® and $44.5 million had been received for certain reimbursements in connection with development and supportive activities. Approximately $4.2 million remains eligible to be received in the future for reimbursements of development and supportive activities.

Table of Contents

For courses of oral TPOXX® that were physically delivered to the Strategic Stockpile under the 2011 BARDA Contract, there are product replacement obligations, including: (i) a product replacement obligation in the event that the final version of oral TPOXX® approved by the FDA was different from any courses of oral TPOXX® that had been delivered to the Strategic Stockpile (the “FDA Approval Replacement Obligation”); (ii) a product replacement obligation, at no cost to BARDA, in the event that oral TPOXX® is recalled or deemed to be recalled for any reason; and (iii) a product replacement obligation in the event that oral TPOXX® does not meet any specified label claims. On July 13, 2018, the FDA approved oral TPOXX® for the treatment of smallpox and there is no difference between the approved product and courses in the Strategic Stockpile. As such, the possibility of the FDA Approval Replacement Obligation resulting in any future replacements of product within the Strategic Stockpile is remote.

The 2011 BARDA Contract includes options. On July 30, 2018, the 2011 BARDA Contract was modified and BARDA exercised its option relating to FDA approval of 84-month expiry for oral TPOXX® for which the Company was paid $50.0 million in August 2018. With the option exercise, the 2011 BARDA Contract was modified so that the 2011 Base Contract increased by $50.0 million . Remaining options, if all were exercised by BARDA, would result in aggregate payments to the Company of $72.7 million , including up to $58.3 million of funding for development and supportive activities such as work on a post-exposure prophylaxis ("PEP") indication for TPOXX® and/or $14.4 million of funding for production-related activities related to warm-base manufacturing. BARDA may choose, in its sole discretion not to exercise any or all of the unexercised options.

The 2011 BARDA Contract expires in September 2020.

Research Agreements and Grants

The Company has an R&D program for IV TPOXX®. This program is funded by the 2018 BARDA Contract and a development contract with BARDA (“IV Formulation R&D Contract”). The IV Formulation R&D Contract has a period of performance that terminates on December 30, 2020. As of June 30, 2019, the IV Formulation R&D Contract provides for future aggregate research and development funding of approximately $4.4 million .

In July 2019, the Company was awarded a multi-year research contract valued at a total of $19.5 million , with an initial award of $12.4 million , from the United States Department of Defense ("DoD") to support work in pursuit of a potential label expansion for oral TPOXX® that would include post-exposure prophylaxis ("PEP") of smallpox (such work known as the "PEP Label Expansion Program" and the contract referred to as the "PEP Label Expansion R&D Contract"). The term of the initial award is five years.

Contracts and grants include, among other things, options that may or may not be exercised at the U.S. Government’s discretion. Moreover, contracts and grants contain customary terms and conditions including the U.S. Government’s right to terminate or restructure a contract or grant for convenience at any time. As such, we may not be eligible to receive all available funds.

7. Financial Instruments

2016 Warrant

On September 2, 2016, in connection with the entry into the Loan Agreement (see Note 8 for additional information), the Company issued a warrant (the “ Warrant ” ) to the Lender to purchase a number of shares of the Company’s common stock equal to $4.0 million divided by the lower of (i) $2.29 per share and (ii) the subscription price paid in connection with the Rights Offering. The Warrant provides for weighted average anti-dilution protection and is exercisable in whole or in part for ten ( 10 ) years from the date of issuance. The per share subscription price paid was $1.50 in connection with the Rights Offering; accordingly, the exercise price of the Warrant was set at $1.50 per share, and there were 2.7 million shares underlying the Warrant. Subsequent to partial exercises of the Warrant, there are approximately 1.5 million shares underlying the Warrant as of June 30, 2019.

The Company accounted for the Warrant in accordance with the authoritative guidance which requires that free-standing derivative financial instruments with certain anti-dilution and cash settlement features be classified as assets or liabilities at the time of the transaction, and recorded at their fair value. Any changes in the fair value of the derivative instruments are reported in earnings or loss as long as the derivative contracts are classified as assets or liabilities. Accordingly, the Company classified the Warrant as a liability and reports the change in fair value in the statement of operations.

As of June 30, 2019 , the fair value of the Warrant was $7.4 million . The fair value of the liability-classified Warrant was calculated using the following assumptions: risk free interest rate of 1.88% ; no dividend yield; an expected life of 7.17 years; and a volatility factor of 65% .

8. Debt

On September 2, 2016, the Company entered into a loan and security agreement (as amended from time to time, the “Loan Agreement”) with OCM Strategic Credit SIGTEC Holdings, LLC (“Lender”), pursuant to which the Company received $80.0 million (less fees and other items) on November 16, 2016 having satisfied certain pre-conditions. Such $80.0 million had been placed in an escrow account on September 30, 2016 (the “Escrow Funding Date”). Prior to the Escrow Release Date (November 16, 2016), the Company did not have access to, or any ownership interest in, the escrow account. Until the Escrow Release Date occurred, the Company did not have an obligation to make any payments under the Loan Agreement, no security was granted under the Loan Agreement and no affirmative or negative covenants or events of default were effective under the Loan Agreement. Amounts were held in the escrow account until the satisfaction of certain conditions including the closing of the Rights Offering (see Note 7 ) on November 16, 2016. As part of the satisfaction of the PharmAthene claim, funds were released from the escrow account (the date on which such transfer occurred, the “Escrow Release Date”).

The Loan Agreement provides for a first-priority senior secured term loan facility in the aggregate principal amount of $80.0 million (the “Term Loan”), of which (i) $25.0 million was placed in a reserve account (the “Reserve Account”) only to be utilized to pay interest on the Term Loan as it becomes due; (ii) an additional $5.0 million was also placed in the Reserve Account and up to the full amount of such $5.0 million was eligible to be withdrawn after June 30, 2018 upon the satisfaction of certain conditions, provided that any of such amount is required to fund any interest to the extent any interest in excess of the aforementioned $25.0 million is due and owing and any of such $5.0 million remains in the Reserve Account; and (iii) $50.0 million (net of fees and expenses then due and owing to the Lender) was paid as part of the final payment to satisfy a litigation claim. Interest on the Term Loan is at a per annum rate equal to the Adjusted LIBOR rate plus 11.5% , subject to adjustments as set forth in the Loan Agreement. At June 30, 2019 , the effective interest rate on the Term Loan, which includes interest payments and accretion of unamortized costs and fees, was 19.3% . The Company incurred approximately $4.0 million of interest expense during the three months ended June 30, 2019, of which $1.1 million accreted to the Term Loan balance. On July 12, 2018, upon confirmation that there had been no events of default, $5 million was withdrawn by the Company from the Reserve Account and was placed in the Company's cash operating account. On October 31, 2018, the Loan Agreement was amended to expand the definition of permitted dispositions to include a sale of the PRV. In connection with the amendment, net cash proceeds from the sale of the PRV ( $78.3 million ) were placed in a restricted cash account; such restricted account is to be used only for interest, fees and principal payments (other than those in connection with an event of default) related to the Term Loan. The cash balance in the restricted account was increased to $100.5 million as of July 24, 2019, in connection with an amendment to the Term Loan that allows the Company to diversify the financial institutions at which its remaining unrestricted cash and cash equivalents can be held. The balance in the restricted account represents an approximation of total payments that would be required pursuant to the Term Loan if it were to remain outstanding until its maturity.

The Term Loan matures on the earliest to occur of (i) the four-year anniversary of the Escrow Release Date, which will be November 16, 2020, and (ii) the acceleration of certain obligations pursuant to the Loan Agreement. At maturity, $80.0 million of principal will be repaid, and an additional $4.0 million will be paid (see below). Prior to maturity, there are no scheduled principal payments.

Through the three and one-half year anniversary of the Escrow Release Date, which will be May 16, 2020, any prepayment of the Term Loan is subject to a make-whole provision in which interest payments related to the prepaid amount are due (subject to a discount of treasury rate plus 0.50% ).

In connection with the Term Loan, the Company has granted the Lender a lien on and security interest in all of the Company’s right, title and interest in substantially all of the Company’s tangible and intangible assets, including all intellectual property.

The Loan Agreement contains customary representations and warranties and customary affirmative and negative covenants. These covenants, among other things, require a minimum unrestricted cash balance throughout the term of the Term Loan and the achievement of regulatory milestones by certain dates, and contain certain limitations on the ability of the Company to incur unreimbursed research and development expenditures over a certain threshold, make capital expenditures over a certain threshold, incur indebtedness, dispose of assets outside of the ordinary course of business, make cash distributions and enter into certain merger or consolidation transactions. The minimum unrestricted cash requirement was $5.0 million until August 27, 2018 ( 45 days after FDA approval of oral TPOXX®), at which point the minimum unrestricted cash requirement became $20.0 million .

The Loan Agreement includes customary events of default, including, among others: (i) non-payment of amounts due thereunder, (ii) the material inaccuracy of representations or warranties made thereunder, (iii) non-compliance with covenants thereunder, (iv) non-payment of amounts due under, or the acceleration of, other material indebtedness of the Company and (v) bankruptcy or insolvency events. Upon the occurrence and during the continuance of an event of default under the Loan Agreement, the interest

Table of Contents

rate may increase by 2.00% per annum above the rate of interest otherwise in effect, and the Lenders would be entitled to accelerate the maturity of the Company’s outstanding obligations thereunder.

As of June 30, 2019 , the Company was in compliance with the Loan Agreement covenants.

In connection with the Loan Agreement, the Company incurred $8.2 million of costs (including interest on amounts held in the escrow account between September 30, 2016 and November 15, 2016). Furthermore, an additional $4.0 million will become payable when principal of the Term Loan is repaid. As part of the Company's entry into the Loan Agreement, the Company issued the Warrant (see Note 7 ) with a fair market value of $5.8 million . The fair value of the Warrant, as well as costs related to the Term Loan issuance, were recorded as deductions to the Term Loan balance on the Balance Sheet. These amounts are being amortized on a straight-line basis over the life of the related Term Loan. The Company compared the amortization under the effective interest method with the straight-line basis and determined the results were not materially different. The $4.0 million that will be paid when principal is repaid is being accreted to the Term Loan balance.

9. Fair Value of Financial Instruments

The carrying value of cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses and other current liabilities approximates fair value due to the relatively short maturity of these instruments. Common stock warrants which are classified as a liability are recorded at their fair market value as of each reporting period.

The measurement of fair value requires the use of techniques based on observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. The inputs create the following fair value hierarchy:


•	Level 1 – Quoted prices for identical instruments in active markets.


•	Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations where inputs are observable or where significant value drivers are observable.


•	Level 3 – Instruments where significant value drivers are unobservable to third parties.

The Company uses model-derived valuations where certain inputs are unobservable to third parties to determine the fair value of certain common stock warrants on a recurring basis and classifies such liability-classified warrants in Level 3. As described in Note 7 , the fair value of the liability classified warrant was $7.4 million at June 30, 2019 .

At June 30, 2019 , the fair value of the debt was $86.6 million and the carrying value of the debt was $77.8 million . The Company used a discounted cash flow model to estimate the fair value of the debt by applying a discount rate to future payments expected to be made as set forth in the Loan Agreement. The fair value of the loan was measured using Level 3 inputs. The discount rate was determined using market participant assumptions.

There were no transfers between levels of the fair value hierarchy for the six months ended June 30, 2019 . In addition, there were no Level 1 or Level 2 financial instruments as of June 30, 2019 and December 31, 2018.

The following table presents changes in the liability-classified warrant measured at fair value using Level 3 inputs:



	Fair Value Measurements of Level 3 liability-classified warrant
Warrant liability at December 31, 2018	$	12,380,939
Decrease in fair value of warrant liability	(3,792,788		)
Exercise of warrants	(1,172,801		)

10. Per Share Data

The Company computes, presents and discloses earnings per share in accordance with the authoritative guidance which specifies the computation, presentation and disclosure requirements for earnings per share of entities with publicly held common stock or potential common stock. The objective of basic EPS is to measure the performance of an entity over the reporting period by dividing income (loss) by the weighted average shares outstanding. The objective of diluted EPS is consistent with that of basic EPS, except that it also gives effect to all potentially dilutive common shares outstanding during the period.

The following is a reconciliation of the basic and diluted loss per share computation:



	Three months ended June 30,						Six months ended June 30,
	2019			2018			2019			2018
Net loss for basic earnings per share	$	(3,162,492	)	$	(7,051,264	)	$	(1,532,715	)	$	(18,633,520	)
Less: Change in fair value of warrants	656,523			360,285			3,792,788			—
Net loss, adjusted for change in fair value of warrants for diluted earnings per share	$	(3,819,015	)	$	(7,411,549	)	$	(5,325,503	)	$	(18,633,520	)
Weighted-average shares	80,986,524			79,094,320			80,950,124			79,066,768
Effect of potential common shares	1,128,137			2,069,066			1,179,477			—
Weighted-average shares: diluted	82,114,661			81,163,386			82,129,601			79,066,768
Loss per share: basic	$	(0.04	)	$	(0.09	)	$	(0.02	)	$	(0.24	)
Loss per share: diluted	$	(0.05	)	$	(0.09	)	$	(0.06	)	$	(0.24	)

For the three and six months ended June 30, 2019, the diluted earnings per share calculation reflects the effect of the assumed exercise of outstanding warrants and any corresponding elimination of the impact included in operating results from the change in fair value of the warrants. Weighted-average diluted shares include the dilutive effect of warrants. The dilutive effect of warrants is calculated based on the average share price for each fiscal period using the treasury stock method.

The Company incurred losses for the three and six months ended June 30, 2019 and 2018 and as a result, the equity instruments listed below were excluded from the calculation of diluted earnings (loss) per share as the effect of the exercise, conversion or vesting of such instruments would be anti-dilutive. The weighted average number of equity instruments excluded consisted of:



	Three months ended June 30,		Six months ended June 30,
	2019	2018	2019	2018
Stock Options	352,015	1,038,071	364,444	1,050,202
Stock-Settled Stock Appreciation Rights	—	160,939	3,359	161,662
Restricted Stock Units (1)	527,082	1,473,155	518,295	1,472,581
Warrant	—	—	—	2,690,950

(1) Includes as of June 30, 2018, 294,118 restricted stock units that had vested but not converted into common stock. As of June 30, 2019, all equity instruments, other than shares related to the Warrant, are unvested.

The appreciation of each stock-settled stock appreciation right was capped at a determined maximum value. As a result, the weighted average number shown in the table above for stock-settled stock appreciation rights reflects the weighted average maximum number of shares that could be issued.

Real Estate Leases

On May 26, 2017 the Company and MacAndrews & Forbes Incorporated (“M&F”) entered into a ten -year Office Lease agreement (the “New HQ Lease”), pursuant to which the Company agreed to lease 3,200 square feet at 31 East 62 ^nd Street, New York, New York. The Company is utilizing premises leased under the New HQ Lease as its new corporate headquarters. The Company's rental obligations consist of a fixed rent of $25,333 per month in the first sixty-three months of the term, subject to a rent abatement for the first six months of the term. From the first day of the sixty-fourth month of the term through the expiration or earlier termination of the lease, the Company's rental obligations consist of a fixed rent of $29,333 per month. In addition to the fixed rent, the Company will pay a facility fee in consideration of the landlord making available certain ancillary services, commencing on the first anniversary of entry into the lease. The facility fee will be $3,333 per month for the second year of the term and increasing by five percent each year thereafter, to $4,925 per month in the final year of the term.

On July 31, 2017, the Company and M&F entered into a Termination of Sublease Agreement (the “Old HQ Sublease Termination Agreement”), pursuant to which the Company and M&F agreed to terminate the sublease dated January 9, 2013 for 6,676 square feet of rental square footage located at 660 Madison Avenue, Suite 1700, New York, New York (such sublease being the “Old HQ Sublease” and the location being the “Old HQ”).

Effectiveness of the Old HQ Sublease Termination Agreement was conditioned upon the commencement of a sublease for the Old HQ between M&F and a new subtenant (the “Replacement M&F Sublease”), which occurred on August 2, 2017. The Old HQ Sublease Termination Agreement obligates the Company to pay, on a monthly basis, an amount equal to the discrepancy (the “Rent Discrepancy”) between the sum of certain operating expenses and taxes (“Additional Rent”) and fixed rent under the overlease between M&F and the landlord at 660 Madison Avenue and the sum of Additional Rent and fixed rent under the Replacement M&F Sublease. Under the Old HQ Sublease Termination Agreement, the Company and M&F release each other from any liability under the Old HQ Sublease.

Under the Old HQ Sublease, the Company was obligated to pay fixed rent of approximately $60,000 per month until August 2018 and approximately $63,400 per month thereafter until the Old HQ Sublease expiration date of August 31, 2020. Additionally, the Company was obligated to pay certain operating expenses and taxes ("Additional Rent"), such Additional Rent being specified in the overlease between M&F and the landlord at 660 Madison Avenue (the "Old HQ Overlease").

Under the Replacement M&F Sublease, the subtenant’s rental obligations were excused for the first two ( 2 ) months of the lease term (“Rent Concession Period”). Thereafter, the subtenant was obligated to pay fixed rent of $36,996 per month for the first

Table of Contents

twelve ( 12 ) months, and is obligated to pay $37,831 per month for the next 12 months, and $38,665 per month until the scheduled expiration of the Replacement M&F Sublease on August 24, 2020. In addition to fixed rent, the subtenant is also obligated to pay, pursuant to the Replacement M&F Sublease, a portion of the Additional Rent specified in the Old HQ Overlease.

For the time period between August 2, 2017 and August 31, 2020 (the expiration date of the Old HQ Sublease), the Company estimates that it will pay a total of approximately $0.9 million combined in fixed rent and additional amounts payable under the New HQ Lease and a total of approximately $1.1 million in Rent Discrepancy under the Old HQ Sublease Termination Agreement, for a cumulative total of $2.0 million . In contrast, fixed rent and estimated Additional Rent under the Old HQ Sublease, for the aforementioned time period, would have been a total of approximately $2.4 million if each of the New HQ Lease, Replacement M&F Sublease and Old HQ Sublease Termination Agreement had not been entered into by each of the parties thereto. Because amounts such as operating expenses and taxes may vary, the foregoing totals can only be estimated at this time and are subject to change.

As a result of the above-mentioned transactions, the Company discontinued usage of Old HQ in the third quarter of 2017. As such, during the year ended December 31, 2017 the Company recorded a loss of approximately $1.1 million in accordance with Accounting Standards Codification ( “ ASC ” ) 420, Exit or Disposal Obligations . This loss primarily represented the discounted value of estimated Rent Discrepancy payments to occur in the future, and included costs related to the termination of the old HQ Sublease. The Company also wrote-off approximately $0.1 million of leasehold improvements and furniture and fixtures related to the Old HQ.

The following table summarizes activity relating to the liability that was recorded as a result of the lease termination:



	Lease Termination liability

13. Income Taxes

The Company’s provision for income taxes consists of federal and state taxes, as applicable, in amounts necessary to align the Company’s year-to-date tax provision with the effective rate that it expects to achieve for the full year. Each quarter the Company updates its estimate of the annual effective tax rate and records cumulative adjustments as necessary.

The effective tax rate for the three months ended June 30, 2019 was 26.15% compared to (0.04)% in the comparable prior period. The effective tax rate for the three months ended June 30, 2019 differs from the U.S. statutory rate of 21% primarily as a result of non-deductible executive compensation under IRC Section 162(m) and a non-taxable adjustment for the fair market value of the Warrant.

The effective tax rate for the six months ended June 30, 2019 was 28.59% compared to 0% in the comparable prior period. The effective tax rate for the six months ended June 30, 2019 differs from the U.S. statutory rate of 21% primarily as a result of non-deductible executive compensation under IRC Section 162(m) and a non-taxable adjustment for the fair market value of the Warrant.

15. Leases

The Company leases its Corvallis, Oregon, facilities and office space under an operating lease which was signed on November 3, 2017 and commenced on January 1, 2018. The initial term of this lease was to expire on December 31, 2019 after which the Company has two successive renewal options; one for two years and the other for three years. In the second quarter of 2019, the Company exercised the first renewal option, which extended the lease expiration date to December 31, 2021.

On May 26, 2017 the Company and M&F entered into a ten -year office lease agreement (the “New HQ Lease”), pursuant to which the Company agreed to lease 3,200 square feet in New York, New York. The Company is utilizing premises leased under the New HQ Lease as its corporate headquarters. The Company has no leases that qualify as finance leases.

Operating lease costs totaled $0.1 million and $0.1 million for the three months ended June 30, 2019 and 2018, respectively, and $0.3 million and $0.3 million for the six months ended June 30, 2019 and 2018, respectively. Cash paid for amounts included in the measurement of lease liabilities from operating cash flows were $0.1 million and $0.1 million for the three months ended June 30, 2019 and 2018, respectively, and $0.3 million and $0.3 million for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019, the weighted-average remaining lease term of the Company’s operating leases was 6.62 years while the weighted-average discount rate was 4.53% .

Future undiscounted cash flows under operating leases as of June 30, 2019 are expected to be as follows:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with our condensed consolidated financial statements and notes to those statements and other financial information appearing elsewhere in this Quarterly Report on Form 10-Q. In addition to historical information, the following discussion and other parts of this Quarterly Report contain forward-looking information that involves risks and uncertainties .

Overview

We are a commercial-stage pharmaceutical company focused on the health security market. Health security comprises countermeasures for biological, chemical, radiological and nuclear attacks (biodefense market), vaccines and therapies for emerging infectious diseases, and health preparedness. Our lead product is an oral formulation of TPOXX® (“oral TPOXX®”), an antiviral drug for the treatment of human smallpox disease caused by variola virus.

BARDA Contracts-TPOXX®

2018 BARDA Contract

On September 10, 2018, the Company entered into a contract with the U.S. Biomedical Advanced Research and Development Authority (“BARDA”) pursuant to which SIGA agreed to deliver up to 1,488,000 courses of oral TPOXX® to the U.S. Strategic National Stockpile ("Strategic Stockpile"), and to manufacture and deliver to the Strategic Stockpile, or store as vendor-managed inventory, up to 212,000 courses of the intravenous (IV) formulation of TPOXX® ("IV TPOXX®"). Additionally, the contract includes funding from BARDA for advanced development of IV TPOXX®, post-marketing activities for oral and IV TPOXX®, and supportive procurement activities. The contract with BARDA (as amended, modified, or supplemented from time to time, the “2018 BARDA Contract”) contemplates, as of June 30, 2019, up to approximately $600.1 million of payments, of which approximately $51.7 million of payments are included within the base period of performance of five years, approximately $23.4 million of payments are related to exercised options and up to approximately $525.0 million of payments are currently classified as unexercised options. BARDA may choose in its sole discretion when, or whether, to exercise any of the unexercised options. The period of performance for options is up to ten years from the date of entry into the 2018 BARDA Contract and such options could be exercised at any time during the contract term, including during the base period of performance. On May 20, 2019, an option for the manufacture and delivery of 363,070 courses of oral TPOXX® was modified to divide it into four procurement-related options. One of the four new procurement-related options provides for the payment of $11.2 million for the procurement of raw materials to be used in the manufacture of at least 363,070 course of oral TPOXX®. This new option was exercised simultaneously with the aforementioned modification. Each of the other three new options individually specifies the delivery of approximately 121,000 courses of oral TPOXX® for consideration of approximately $34.0 million . In total, the four new options provide for the manufacture and delivery of 363,070 courses of oral TPOXX® for consideration of approximately $112.5 million . The option modification did not change the overall total potential value of the 2018 BARDA Contract, nor did it change the total amount to be paid in connection with the manufacture and delivery of oral TPOXX® courses.

The base period of performance provides for potential payments of approximately $51.7 million for the following activities: payments of approximately $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile; payments of $8.0 million for the manufacture of 20,000 courses of final drug product of IV TPOXX® ("IV FDP"), of which $3.2 million of payments are related to the manufacture of bulk drug substance ("IV BDS") to be used in the manufacture of IV FDP; payments of approximately $32.0 million to fund advanced development of IV TPOXX®; and payments of approximately $0.6 million for supportive procurement activities. As of June 30, 2019, the Company had received $7.1 million for the first quarter 2019 delivery of approximately 23,000 courses of oral TPOXX® to the Strategic Stockpile and $3.2 million for the 2018 manufacture of IV BDS. IV BDS is expected to be used for the manufacture of 20,000 courses of IV FDP. The $3.2 million received for the manufacture of IV BDS has been recorded as deferred revenue as of December 31, 2018 and June 30, 2019.

of IV FDP, of which up to $30.7 million of payments would be paid upon the manufacture of IV BDS to be used in the manufacture of IV FDP; payments of up to approximately $3.6 million to fund post-marketing activities for IV TPOXX®; and payments of up to approximately $5.6 million for supportive procurement activities.

Research Agreements and Grants

In July 2019, the Company was awarded a multi-year research contract valued at a total of $19.5 million, with an initial award of $12.4 million , from the United States Department of Defense ("DoD") to support work in pursuit of a potential label expansion for oral TPOXX® that would include post-exposure prophylaxis ("PEP") of smallpox (such work known as the "PEP Label Expansion Program" and the contract referred to as the "PEP Label Expansion R&D Contract"). The term of the initial award is five years.

Critical Accounting Estimates

The methods, estimates and judgments we use in applying our accounting policies have a significant impact on the results we report in our condensed consolidated financial statements, which we discuss under the heading “Results of Operations” following this section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Information regarding our critical accounting policies and estimates appear in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the year ended December 31, 2018 as filed on March 5, 2019. Our most critical accounting estimates include revenue recognition, the valuation of stock-based awards including options and warrants granted or issued by the Company and income taxes.

Results of Operations

Three Months Ended June 30, 2019 Compared to Three Months Ended June 30, 2018

For the three months ended June 30, 2019 and 2018, there were no recorded revenues from product sales and supportive services.

Revenues from research and development activities for the three months ended June 30, 2019 and 2018 , were $3.9 million and $2.7 million , respectively. The increase in revenue of approximately $1.2 million, or 47% , primarily reflects the net effect of: the conclusion of historical rate reconciliations under the IV Formulation R&D Contract; changes to the projected amount of contract funding expected to be available for future activities under the IV Formulation R&D Contract; and a decrease in activities performed in the quarter under the IV Formulation R&D Contract. The conclusion of historical rate reconciliations and changes to expectations for available funding, in combination, increased revenues approximately $3.3 million. This increase was partially offset by a decrease in research activities that led to a decline in revenues of approximately $1.9 million. The conclusion of historical rate reconciliations, and the change in the projected amount of contract funding under the IV Formulation R&D Contract, impacts

the progress-towards-completion calculation as required under ASC Topic 606, Revenue from Contracts with Customers ("ASC 606").

Selling, General and Administrative (“SG&A”) expenses for the three months ended June 30, 2019 and 2018 , were $3.4 million and $2.9 million , respectively, reflecting an increase of approximately $0.5 million, or 17.8% . The increase is primarily attributable to an approximate $0.2 million increase in compensation expense and an approximate $0.3 million increase in consulting costs.

Research and Development (“R&D”) expenses for the three months ended June 30, 2019 and 2018 were $2.0 million and $3.3 million , respectively, reflecting a decrease of approximately $1.3 million , or 38% . The decrease is primarily attributable to a $1.6 million decrease in direct vendor-related expenses supporting the development of IV TPOXX®, partially offset by an increase in other R&D-related costs.

Patent expenses were $0.2 million , in each case, for the three months ended June 30, 2019 and 2018. These expenses reflect our ongoing efforts to protect our lead drug candidates in various geographic territories.

Interest expense for the three months ended June 30, 2019 and 2018 was $4.0 million and $3.8 million , respectively. The $4.0 million of interest for the three months ended June 30, 2019 includes $1.1 million of accretion of unamortized costs and fees related to the Term Loan balance. The increase in interest expense is attributable to LIBOR rates being higher this quarter versus LIBOR rates in the same period last year.

Changes in the fair value of the liability-classified warrant to acquire common stock were recorded within the income statement. For the three months ended June 30, 2019 and 2018, we recorded a gain of approximately $0.7 million and $0.4 million, respectively, reflecting a decrease in the fair value of the liability-classified warrant primarily due to the decrease in our stock price.

Other income of $0.7 million for the three months ended June 30, 2019 reflects interest income on the Company's cash balance held in restricted and unrestricted accounts.

For the three months ended June 30, 2019 and 2018 , we incurred pre-tax losses of $4.3 million and $7.0 million , respectively, and a corresponding income tax benefit/(expense) of $1.1 million and $(2,849) , respectively. The effective tax rate during the three months ended June 30, 2019 and 2018 was 26.15% and (0.04)%, respectively. Our effective tax rate for the period ended June 30, 2019 differs from the statutory rate primarily as a result of non-deductible executive compensation under IRC Section 162(m) and a non-taxable adjustment for the fair market value of the Warrant. Our effective tax rate for the period ended June 30, 2018 differs from the statutory rate as no income tax benefit was recorded for operating losses due to the Company’s assessment regarding realizability of its deferred tax assets.

Six Months Ended June 30, 2019 Compared to Six Months Ended June 30, 2018

Revenues from product sales and supportive services for the six months ended June 30, 2019 were $7.1 million . In 2018, there were no recorded revenues from product sales and supportive services. Such revenues in 2019 were associated with the delivery of approximately 23,000 courses of oral TPOXX® to the Strategic Stockpile under the 2018 BARDA Contract.

Revenues from research and development activities for the six months ended June 30, 2019 and 2018 , were $7.2 million and $4.4 million , respectively. The increase in revenue of approximately $2.8 million , or 64% , primarily reflects the conclusion of historical rate reconciliations under the IV Formulation R&D Contract and a change in the projected amount of contract funding expected to be available for future activities under the IV Formulation R&D Contract. Such events impacted the progress-towards-completion calculation as required under ASC 606, and resulted in a cumulative catch-up adjustment to revenue of approximately $3.3 million.

Cost of sales and supportive services for the six months ended June 30, 2019, were $0.9 million ; in 2018, there were no recorded cost of sales and supportive services. Such costs in 2019 are associated with the delivery of approximately 23,000 courses of oral TPOXX® during the six months ended June 30, 2019.

Selling, General and Administrative (“SG&A”) expenses for the six months ended June 30, 2019 and 2018 , were $6.6 million and $5.9 million , respectively, reflecting an increase of approximately $0.7 million, or 10% . The increase is primarily attributable to an approximate $0.2 million increase in compensation expense and an approximate $0.5 million increase in consulting costs and professional service fees, partially offset by the non-recurrence of Nasdaq application fees that were incurred in the second quarter of 2018.

Table of Contents

Research and Development (“R&D”) expenses for the six months ended June 30, 2019 and 2018 were $6.0 million and $6.3 million , respectively, reflecting a decrease of approximately $0.3 million , or 5% . The decrease is primarily attributable to a $0.9 million decrease in direct vendor-related expenses supporting the development of IV and oral TPOXX® and partially offset by an increase of $0.4 million in compensation expense.

Patent expenses were $0.4 million , in each case, for the six months ended June 30, 2019 and 2018. These expenses reflect our ongoing efforts to protect our lead drug candidates in various geographic territories.

Interest expense for the six months ended June 30, 2019 and 2018 was $7.9 million and $7.6 million , respectively. The $7.9 million of interest for the six months ended June 30, 2019 includes $2.2 million of accretion of unamortized costs and fees related to the Term Loan balance. The increase in interest expense for the six months ended June 30, 2019 is attributable to LIBOR rates being higher this period versus LIBOR rates in the same period last year.

Changes in the fair value of the liability-classified warrant to acquire common stock were recorded within the income statement. For the six months ended June 30, 2019, we recorded a gain of approximately $3.8 million reflecting a decrease in the fair value of the liability-classified warrant primarily due to the decrease in our stock price. For the six months ended June 30, 2018, we recorded a loss of approximately $2.9 million reflecting an increase in fair value of the liability-classified warrant primarily due to the increase in our stock price.

Other income of $1.5 million for the six months ended June 30, 2019 reflects interest income on the Company's cash balance held in restricted and unrestricted accounts.

For the six months ended June 30, 2019 and 2018 , we incurred pre-tax losses of $2.1 million and $18.6 million , respectively, and a corresponding income tax benefit/(loss) of $0.6 million and ($497), respectively. The effective tax rate during the six months ended June 30, 2019 and 2018 was 28.59% and 0%, respectively. Our effective tax rate for the period ended June 30, 2019 differs from the statutory rate primarily as a result of non-deductible executive compensation under IRC Section 162(m) and a non-taxable adjustment for the fair market value of the Warrant. Our effective tax rate for the period ended June 30, 2018 differs from the statutory rate as no income tax benefit was recorded for operating losses due to the Company’s assessment regarding realizability of its deferred tax assets.

Liquidity and Capital Resources

As of June 30, 2019 , we had $100.3 million in cash and cash equivalents compared with $100.7 million at December 31, 2018. Additionally, as of June 30, 2019 , we had $75.7 million of restricted cash compared with $79.7 million at December 31, 2018. The restricted cash is available to pay interest, fees and principal related to the Term Loan.

The cash balance in the restricted account was increased to $100.5 million, as of July 24, 2019, in connection with an amendment to the Term Loan that allows the Company to diversify the financial institutions at which its remaining unrestricted cash and cash equivalents are held. The balance in the restricted account represents an approximation of total payments that would be required pursuant to the Term Loan if it were to remain outstanding until its maturity.

Operating Activities

We prepare our condensed consolidated statement of cash flows using the indirect method. Under this method, we reconcile net income (loss) to cash flows from operating activities by adjusting net income (loss) for those items that impact net income (loss) but may not result in actual cash receipts or payments during the period. These reconciling items include but are not limited to stock-based compensation, deferred income taxes, non-cash interest expense and changes in the fair value of our warrant liability; gains and losses from various transactions and changes in the condensed consolidated balance sheet for working capital from the beginning to the end of the period.

Net cash used in operations for the six months ended June 30, 2019 and 2018 was $4.3 million and $13.7 million , respectively. For the six months ended June 30, 2019, we incurred $5.7 million of cash interest expense on the Term Loan and used approximately $1.8 million in support of ordinary course working capital (accounts receivable, accounts payable, prepaids, among other items). Additionally, cash was used for customary operating activities. These cash uses were partially offset by the receipt of approximately $7.1 million from BARDA for product delivery. For the six months ended June 30, 2018, cash usage was primarily due to $7.3 million of cash operating expenses (net loss adjusted for non-cash items noted in the cash flow statement such as non-cash interest expense and the change in the fair value of our warrant) and $5.4 million of cash interest expense on the Term Loan.

Table of Contents

Investing Activities

For the six months ended June 30, 2019 and 2018 we used cash in the amounts of $8,948 and $27,863 , respectively, for capital expenditures.

Financing Activities

Net cash used by financing activities for the six months ended June 30, 2019 and 2018 was $56,590 and $12,328 , respectively, which was attributable to the payment of tax obligations for employee common stock tendered.

Off-Balance Sheet Arrangements

The Company does not have any off-balance sheet arrangements.

SIGA’s actual results could differ materially from those anticipated by such forward-looking statements due to a number of factors, some of which are beyond SIGA’s control, including, but not limited to, (i) the risk that BARDA elects, in its sole discretion as permitted under the BARDA Contracts, not to exercise all, or any, of the remaining unexercised options under those contracts, (ii) the risk that SIGA may not complete performance under the BARDA Contracts on schedule or in accordance with contractual terms, (iii) the risk that the BARDA Contracts are modified or canceled at the request or requirement of the U.S. government, (iv) the risk that the nascent international biodefense market does not develop to a degree that allows SIGA to successfully market TPOXX® internationally, (v) the risk that potential products, including the IV formulation of TPOXX®, or potential alternative uses of TPOXX® that appear promising to SIGA or its collaborators, cannot be shown to be efficacious or safe in subsequent pre-clinical or clinical trials, (vi) the risk that SIGA or its collaborators will not obtain appropriate or necessary governmental approvals to market these or other potential products or uses, (vii) the risk that SIGA may not be able to secure or enforce sufficient legal rights in its products, including intellectual property protection, (viii) the risk that any challenge to SIGA’s patent and other property rights, if adversely determined, could affect SIGA’s business and, even if determined favorably, could be costly, (ix) the risk that regulatory requirements applicable to SIGA’s products may result in the need for further or additional testing or documentation that will delay or prevent seeking or obtaining needed approvals to market these products, (x) the risk that changes in domestic or foreign economic and market conditions may affect SIGA’s ability to advance its research or may affect its products adversely, (xi) the effect of federal, state, and foreign regulation, including drug regulation and international trade regulation, on SIGA’s businesses and (xii) the risk that the U.S. government’s responses (including inaction) to the national or global economic situation may affect SIGA’s business adversely, as well as the risks and uncertainties included in Item 1A “Risk Factors” on Form 10-K for the fiscal year ended December 31, 2018.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our investment portfolio includes cash and cash equivalents. Our main investment objectives are the preservation of investment capital. We believe that our investment policy is conservative, both in the duration of our investments and the credit quality of the investments we hold. We do not utilize derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments, positions or transactions to manage exposure to interest rate changes. As such, we believe that, the securities we hold are subject to market risk, changes in the financial standing of the issuer of such securities and our interest income is sensitive to changes in the general level of U.S. interest rates. Additionally, we are also subject to the risk of rising LIBOR rates; whenever the minimum rates for one-month, two-month, three-month and six-month LIBOR rates (“minimum LIBOR rate”) are above 1%, then the interest rate charged on the Term Loan could increase materially depending on the magnitude of any increase in LIBOR rates. For every increase of 0.5% in the minimum LIBOR rate (e.g., an increase from a LIBOR rate of 2.50% to 3.00% ), annual interest payments on the Term Loan would increase by approximately $0.4 million . Furthermore, we are

subject to the impact of stock price fluctuations of our common stock in that we have a liability-classified warrant in which 1.5 million shares of SIGA common stock can be purchased at a strike price of $1.50 per share. For every $1 increase in the stock price of SIGA, the intrinsic value of the liability-classified warrant will increase by approximately $1.5 million .

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2019 . The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. Management recognizes that any disclosure controls and procedures no matter how well designed and operated, can only provide reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2019 at a reasonable level of assurance.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended June 30, 2019 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
