ITEM 1 –BUSINESS

Overview of the Company

Simulations Plus, Inc., which was incorporated in California in 1996 (“Simulations Plus”, or together with Words+, Inc. (“Words+”) its wholly owned subsidiary referred to as the “Company,” “us,” “we,” or “our”), develops and produces software for use in pharmaceutical research and for education, as well as providing contract research services to the pharmaceutical industry. Simulations Plus has also taken over responsibility for producing a personal productivity software program called Abbreviate!, originally spun out of products for the disabled by Words+ for the retail market. Words+, which was incorporated in California in 1981, produces computer software and specialized hardware for use by persons with disabilities. For the purposes of this document, we sometimes refer to the two businesses as “Simulations Plus” when referring to the business of pharmaceutical software and services, educational software, and Abbreviate!, and “Words+” when referring to the business that is focused on assistive technologies for persons with disabilities. However, Simulations Plus has entered into a stock purchase agreement with the Prentke Romich Company of Wooster, Ohio (“PRC”) to sell all of Simulations Plus’ shares of Words+ to PRC. The anticipated closing of the sale of Words+ to PRC is November 30, 2011. Thus, if the sale transaction closes as anticipated, Words+ will be treated as “discontinued operations” going forward. See Note 11: Subsequent Events under the Notes to the Financial Statements included in this Annual Report on Form 10-K for more information.

PRODUCTS

We currently offer five software products for pharmaceutical research: ADMET Predictor™, MedChem Studio™, MedChem Designer™, DDDPlus™, and GastroPlus™.

ADMET Predictor™

Every drug molecule that fails in clinical trials, and every approved drug that gets withdrawn from the market, was doomed to fail from the time its structure was first drawn by a chemist or generated by a computer - they do not become bad later in development. The enormous resources that were required to bring these drugs to human trials and sometimes to market are wasted. Thus, the ability to predict unsuitable characteristics of new molecules as early as possible offers the promise of avoiding costly programs that end up as late-stage failures. Although not every failure mode can be predicted in this manner, those that can provide a means to reduce the number of failures that frequently occur after years of work and sometimes more than a billion dollars have been spent.

ADMET (Absorption, Distribution, Metabolism, Excretion and Toxicity) Predictor provides a collection of highly sophisticated and statistically significant numerical models that predict various properties of chemical compounds from just their molecular structures. Our models are built using proprietary machine learning approaches that are based primarily on artificial neural network ensembles (groups of artificial neural networks).

Having this capability means a chemist can merely draw a molecule diagram and get estimates of a wide variety of properties, even though the molecule has never existed. Drug companies continually search through millions of such “virtual” molecular structures as they attempt to find new drugs. It has been estimated that there are somewhere on the order of 10 62 possible drug-like molecular structures. That is such a huge number that it is difficult to comprehend. If we could evaluate a trillion molecules (10 12 ) per second (we cannot), it would still take 10 50 seconds to evaluate them all -- that’s about 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years. The age of the universe is said to be much less than 100,000,000,000 years. Clearly, we will never be able to make and test all of them, so computerized methods are the only hope to even scratch the surface of the total “chemical space” for potential pharmaceutical products.

The vast majority of drug-like molecules are not suitable as medicines for various reasons. Some have such low solubility that they will not dissolve well, some have such low permeability through cell walls that they will not be absorbed well, some degrade so quickly that they are not stable enough to have a useful shelf life, some bind to proteins (such as albumin) in blood to such a high extent that little unbound drug is available to reach the target, and many will produce a variety of adverse effects. Identification of such properties in the computer (“ in silico”) enables researchers to rapidly eliminate poor compounds before spending time and money to make them and run experiments to identify their weaknesses. Today, many potential new molecules can be eliminated on the basis of the properties predicted by ADMET Predictor without the need to actually make and test them. We continue to add predictive models for additional properties to allow eliminating even more unsuitable molecules as early as possible.

Several independent studies have been published that compare the accuracy of software programs like ADMET Predictor. In almost every case, ADMET Predictor has been ranked first in accuracy. The specific set of molecules used in such studies, as well as the statistics used for comparison, often favors one program over others; however, across all published studies, ADMET Predictor has been top-ranked far more than any other program.

ADMET Predictor includes a subprogram called ADMET Modeler™ as an optional module. ADMET Modeler was first released in 2003 as a separate product (with the name QMPRchitect™), and was integrated into ADMET Predictor in 2006. This powerful program is what we use to train our own best-in-class predictive models in ADMET Predictor. Having it available within ADMET Predictor means our users can train their own proprietary models using their own data for various properties and add them to the commercial models we provide. ADMET Modeler automates the complex training process, so very high quality models are produced in a small fraction of the time once required, and without the need for an expert modeler (although an expert modeler might achieve slightly better results). For example, new models are typically developed in a matter of a few minutes to a few hours once we complete the tedious effort of “cleaning up” the databases (which often contain a significant number of errors). Prior to the availability of ADMET Modeler, we needed as much as three months to develop each new model after cleaning the database.

Pharmaceutical companies spend enormous amounts of money conducting a wide variety of experiments on new molecules each year. Using their own proprietary data to build predictive models provides a second return on this investment; however, in the past, model-building has traditionally been a tedious activity performed by specialists. With ADMET Modeler integrated into ADMET Predictor, scientists without model-building experience can now use their own experimental data to quickly create high-quality predictive models.

ADMET Predictor is compatible with the popular Pipeline Pilot™ software offered by Accelrys, Inc. This software serves as a tool to allow chemists to run several different software programs in series to accomplish a set workflow for very large numbers of molecules. In early discovery, chemists often work with hundreds of thousands or millions of “virtual” molecules – molecules that exist only in computer files. Chemists need to decide which few molecules from these large “libraries” should be made and tested or taken further in development. Using Pipeline Pilot with ADMET Predictor (and MedChem Studio – see below), perhaps in conjunction with other software products, chemists can create and screen very large libraries faster and more efficiently than by running each program by itself. Perhaps the most important aspect of this process is obtaining sufficiently accurate property predictions for new molecular structures, so that molecules are not filtered out of the process that would have been successful as medicines, and molecules that cannot become useful medicines are eliminated from wasteful further development activities. Because of ADMET Predictor’s accuracy, we believe we have a significant strategic advantage in this developing area of technology.

MedChem Studio™

We have renamed our former ClassPharmer product to MedChem Studio to reflect the greatly enhanced capabilities it now has over the original acquired ClassPharmer product. MedChem Studio has become a powerful tool for medicinal and computational chemists both for data mining and for designing new drug-like molecules. Coupled with the accurate property predictions in ADMET Predictor, the two programs provide an unmatched capability for chemists to search through existing huge libraries of compounds to find the most promising classes and molecules that are active against a particular target. In addition, MedChem Studio with ADMET Predictor can take interesting (but not acceptable) molecules and very quickly generate high quality analogs (i.e., similar new molecules) using several different algorithms. The result is new molecules that are predicted to be both active against the target as well as acceptable in a variety of ADMET properties.

MedChem Studio’s molecule design capabilities provide a number of ways for chemists to rapidly generate large numbers of novel chemical structures based on intelligence from compounds that have already been synthesized and tested, or from basic chemical reactions selected by the user. Export of results is available in Microsoft Excel® format as well as other convenient file formats requested by users.

MedChem Designer™

Most chemists love to draw molecules. Molecule “sketchers” or drawing programs exist from several sources and are considered an essential part of the medicinal chemist’s toolbox. Most of these programs are free, provided by their authors as a way to interface with other software. We launched MedChem Designer in February 2011 as a free program to help promote our ADMET Predictor and MedChem Studio products. MedChem Designer provides a highly intuitive interface for molecule sketching along with best-in-class property prediction from ADMET Predictor. We have made MedChem Designer an integral part of MedChem Studio, as well as a standalone product that can be downloaded and unlocked at no charge. The free version includes a small number of predicted properties from ADMET Predictor – basically, a way to introduce the power of combined molecule design with predicted properties that let the chemist quickly see the effects of changing molecular structures. Although a few properties are provided for free, the chemist can see that more than one hundred additional properties would be provided if they obtain a license for ADMET Predictor.

DDDPlus™

Oral doses make up about 80% of all drug doses. Formulation scientists run many experiments in the lab to measure the rate at which new formulations (tablets and capsules) will dissolve. Doing this requires making the tablet or capsule, which consists of not only the active pharmaceutical ingredient (“API”) but also a number of excipients that serve various purposes: to make a tablet strong enough to survive both manufacturing processes as well as shipping without crumbling; glidants to promote the flow of powders from source hoppers into tablet-making machines; lubricants for the machines; to control the surface behavior to make the table or capsule practical in a variety of environments with a wide range of temperature and humidity; and to make the API cost-effective to manufacture.

Often, meeting one requirement is at the cost of another. For example, increasing tablet strength can result in slower dissolution. Slower dissolution can be a disadvantage if the drug cannot be absorbed and get into the blood to do its job. Often, formulation design is an iterative process of making tablets or capsules, testing them, analyzing the results, cleaning up the manufacturing equipment and test lab, then doing it again and again until a suitable formulation is achieved.

DDDPlus simulates the in vitro laboratory experiments that measure the rate of dissolution of the drug contained in tablets and capsules in a variety of experimental conditions. This one-of-a-kind software program is used by formulation scientists to reduce the number of cut-and-try attempts to design new drug formulations, as well as to design in vitro experiments to better mimic in vivo conditions. During 2011, improvements were added to further enhance the value of this product, including numerous user convenience features, as well as more sophisticated handling of dosage forms that incorporate multiple polymers for controlled release formulations. The Food and Drug Administration (FDA) and a growing number of companies use DDDPlus in their work.

GastroPlus™

GastroPlus is our flagship product, producing about 65% of our pharmaceutical software and services revenues. It simulates the absorption, pharmacokinetics, and pharmacodynamics of drugs administered to humans and animals, and is currently in use at numerous pharmaceutical companies, the FDA, and other government agencies in the U.S. and other countries.

At an international conference in Shanghai, China, in 2008, Pfizer scientists presented a scientific poster describing a two-year study in which all four commercially available PBPK (physiologically based pharmacokinetics) simulation programs were compared for their ability to predict human pharmacokinetics from preclinical (animal and in vitro) data. The study was divided into two arms: intravenous and oral dosing. GastroPlus was ranked first in both arms. No other software was ranked consistently in the top three.

The insight gained through GastroPlus simulations can guide project decisions in various ways. Among the kinds of knowledge gained through such simulations are: (1) the best estimate for “first dose in human” for a new drug prior to Phase I trials, (2) whether a potential new drug compound is likely to be absorbed at high enough levels to achieve the desired blood concentrations needed for effective therapy, (3) whether the absorption process is affected by certain enzymes and transporter proteins in the intestinal tract that may in turn affect the amount of drug reaching the blood , (4) when certain properties of a new compound are probably adequately estimated by in silico predictions (such as from ADMET Predictor) or from simple experiments, rather than through more expensive and time-consuming in vitro or animal experiments, (5) what the likely variations in blood and tissue concentration levels of a new drug would be in a large population, in different age groups or in different ethnic groups, and (6) whether a new formulation for an existing approved drug is likely to demonstrate “bioequivalence” (equivalent blood concentration versus time) to a currently marketed dosage form in a human trial (important for generic drug companies and the Office of Generic Drugs at the FDA).

Our marketing intelligence and reorder history indicate that GastroPlus continues to dominate its market niche in the number of users worldwide. In addition to virtually every major pharmaceutical company, licenses include government agencies in the U.S and abroad, a growing number of smaller pharmaceutical and biotech companies, generic drug companies, and drug delivery companies (companies that design the tablet or capsule for a drug compound that was developed by another company). Although these companies are smaller than the pharmaceutical giants, we believe they can also save considerable time and money through simulation. We believe this part of the industry, which we believe includes a few thousand companies, represents major growth potential for GastroPlus. Our experience has been that the number of new companies adopting GastroPlus continues to grow steadily, adding to the base of annual license renewals each year. Recent consolidations by larger companies have not affected our sales to date. In fact, because of the increased need for improving productivity, those companies have typically adopted in silico tools at ever-greater levels, with the result that large company licenses have typically increased at renewal time even in the face of such consolidation.

Contract Research and Consulting Services

Our recognized world-class expertise in oral absorption and pharmacokinetics is evidenced by the fact that our staff members have been speakers or presenters at approximately 75 prestigious scientific meetings worldwide in the past two years. We frequently conduct contracted studies for large customers (including top 5 pharmaceutical companies) who have particularly difficult problems and who recognize our expertise in solving them, as well as for smaller customers who prefer to have studies run by our scientists rather than to license our software and train someone to use it. The demand for our consulting services has been increasing steadily, and we expect this trend to continue. Long-term collaborations and shorter-term consulting contracts serve both to showcase our technologies and to build and strengthen customer relationships.

Government-Funded Research

We completed our Small Business Innovation Research (SBIR) grant from the National Institutes of Health (NIH) during fiscal year 2011. This three-year effort led to the development of our rapid atomic partial charge calculations in ADMET Predictor, which in turn has led to the ability to predict metabolism and metabolic sites (i.e., which atoms on a molecule are likely to be attacked by certain enzymes). The result, we believe, is the most accurate prediction of metabolism and metabolic sites available today. This is expected to be released in ADMET Predictor Version 6.0 before the end of calendar year 2011.

PHARMACEUTICAL SOFTWARE PRODUCT DEVELOPMENT

Although all of our development work cannot be disclosed for competitive reasons, some of our development efforts during this reporting period included:

(1) ADMET Predictor/ADMET Modeler Upgrades

In February 2011, we released version 5.5 of ADMET Predictor with a number of new features:

A new Metabolite Module with 10 new models for sites of metabolism

An expanded Toxicity Module with 9 new models, extending the total number to over 30

An expanded Enslein Metabolism Module

An expanded Physicochemical and Biopharmaceutical Properties Module

Expanded ADMET Risk™ capabilities for multiobjective molecule design optimization

Expanded ADMET Modeler™ model-building capabilities

Enhanced graphics presentations for visualization of new calculated properties

We believe these new features enhance the value of ADMET Predictor for our pharmaceutical customers, project ADMET Predictor further into the markets for toxicity prediction, both environmental and pharmaceutical, and enhance the combination of our MedChem Studio™ data mining and molecule design software through the integration of ADMET Predictor with MedChem Studio and the new powerful ADMET Risk capabilities.

In version 6.0 of ADMET Predictor, which we expect to release before the end of calendar year 2011, we are adding a number of new models as well as revising the user interface to make the problem more flexible and friendly.

(2) MedChem Studio

We launched MedChem Studio 2.0 in April 2011 with:

Our new MedChem Designer advanced molecule drawing tool

Greatly expanded multidimensional graphics output

Enhanced import capabilities for molecular structure files

Enhanced capabilities for exporting results

Additional improvements to our industry-best structure depictions

With the MedChem Studio/MedChem Designer/ADMET Predictor combination, chemists now have the capability to see how changes in molecular structures affect not just one or a handful of properties, but over 130 properties from the industry’s top-ranked property prediction program, ADMET Predictor. We believe that this represents the future for drug discovery and that no other technology offers as much potential for reducing the time and money required to discover new structures that can become tomorrow’s medicines.

Ongoing developments are directed toward continued expansion of the program’s molecule design and data mining capabilities, including enhanced plotting of multidimensional data to better enable chemists to see how various molecular structures are distributed with respect to a variety of molecular features and predicted properties from ADMET Predictor.

(3) MedChem Designer

MedChem Designer was launched in February 2011. This new product is provided free as a standalone program, as well as integrated into MedChem Studio.

Unique features of MedChem Designer include:

Intuitive interface with many innovative features for molecular structure drawing and manipulation

Several free predicted key molecular properties from our top-rated ADMET Predictor software

With a full ADMET Predictor license, a wide range of predicted properties:

Physicochemical properties

Pharmacokinetic parameters

Cytochrome P450 (CYP) enzyme metabolism rates

CYP inhibition

Sites of CYP oxidation

UGT metabolism

Over 30 potential toxicities

Partial atomic charges and reactivities based on our proprietary rapid quantum chemical descriptor calculations

(4) DDDPlus

DDDPlus 4.0 was launched in June 2011 with several enhancements:

Expanded Parameter Sensitivity Analysis

New Virtual Trial capability

New immediate release capsule dosage form

Variety of enhanced input and output functions

(5) GastroPlus

Intensive development efforts have been ongoing in our flagship GastroPlus software during this fiscal year. These include expansion of the Drug-Drug Interaction Module to incorporate transporters as well as induction of both enzymes and transporters. This new capability completes the drug-drug interaction picture, allowing scientists to model all of the most common drug-drug interaction mechanisms that complicate dosing to patients with multiple medications. Most patients take more than one medication – some as many as 8-10 per day or more. When two or more drugs compete for the same enzymes or transporters, interactions can have a helpful or a harmful effect. The Drug-Drug Interaction Module in GastroPlus is designed to enable pharmaceutical scientists to analyze the potential for interactions before they occur, and to provide guidance for whether dosing regimens (how much of each drug and when) might need to be adjusted to either take advantage of helpful interactions or to avoid those that could cause adverse effects.

The PDPlus™ Module for modeling pharmacodynamic effects has undergone considerable enhancements, now allowing automatic fitting of all of its models to find the most appropriate mathematical form to describe pharmacodynamic effect (the effect of the drug on the body, as opposed to pharmacokinetic effect – the effect of the body on the drug).

A large number of other program enhancements have been in development and are expected to be released with the launch of version 8.0, currently expected in December 2011.

(6) MembranePlus™

MembranePlus is a computer program that simulates in vitro experiments that measure the permeability of new drug-like molecules through a layer of living cells or through an artificial membrane. These experiments are conducted in order to estimate the permeability of new drug compounds through the cells lining the intestinal walls and other tissues of humans and various animals. However, such experiments often do not produce results that are easily translated into in vivo permeabilities. We believe that a detailed mechanistic simulation of such in vitro experiments can provide the insight and understanding needed to provide reasonably accurate estimates of permeability in different regions of human and animal tissues from in vitro data.

This development effort accelerated during fiscal year 2005 with the hiring of a new Ph.D. scientist who focused on this program. The simulation is currently predicting the movement of drug molecules from the bulk fluid, into the membranes at the surface of a cell layer, through the surface membrane, through the interior of the cell, into the opposite surface membrane, and through it to the bulk fluid on the opposite side of the cell layer. Although a few technical issues remain to be resolved, we are optimistic that the simulation can become a unique tool for the analysis of data from these experiments, and can enable researchers to more accurately estimate human intestinal permeability from these in vitro experiments.

This project was put on hold in late 2005 because the scientist responsible for MembranePlus, Dr. Viera Lukacova, was assigned to take over GastroPlus when the previous product manager left the company. New additions to the Simulation Technologies Team are currently working on GastroPlus version 8.0, but we expect one will be assigned to work on MembranePlus after GastroPlus 8.0 is released.

MARKETING AND DISTRIBUTION

We market our pharmaceutical software and consulting services through attendance and presentations at scientific meetings, exhibits at trade shows, seminars at pharmaceutical companies and government agencies, through our web pages on the Internet, and using various communication media to our compiled database of prospect and customer names. At the American Association of Pharmaceutical Scientists (AAPS) conference in Washington, D.C., in October 2011, there were twenty different presentations and posters presented in which the research that was reported was done using GastroPlus. Fifteen of those were from industry and FDA scientists, five were from our staff.

In recent months we added an independent sales representative in Europe, and we have two independent representatives in China; however, our scientific team is also the majority of our sales and marketing team, assisting our Director of Marketing and Sales with trade shows, seminars, and customer training both via Internet and on-site. We believe that this is more effective than a completely separate sales team for several reasons: (1) customers appreciate talking directly with developers who can answer a wide range of technical questions about methods and features, (2) our scientists benefit from direct customer contact by gaining an appreciation for the environment and problems of the customer, and (3) the relationships we build through scientist-to-scientist contact are stronger than through salesperson-to-scientist contacts.

We use the Internet to provide product information and software updates, and as a forum for user feedback and information exchange. We have cultivated market share in North America, South America, Europe, Australia, New Zealand, Singapore, People’s Republic of China, and Japan, and Internet and e-mail technologies have had a positive influence on our ability to communicate with existing and potential customers worldwide.

PRODUCTION

Our pharmaceutical software products are designed and developed entirely by our development team in California, with locations in Lancaster, Petaluma, San Jose, and San Diego. The principal materials and components used in the manufacture of simulation software products include CD-ROMs and instruction manuals, which are also produced in-house and through outside contractors. In-house graphic art and engineering talent enables us to accomplish this production in a cost-efficient manner.

COMPETITION

In our pharmaceutical software and services business, we compete against a number of established companies that provide screening, testing and research services, and products that are not based on simulation software. There are also software companies whose products do not compete directly, but are sometimes closely related. Our competitors in this field include some companies with financial, personnel, research and marketing resources that are greater than ours. Management believes there is currently no significant competitive threat to GastroPlus or DDDPlus, however, one could be developed in time. MedChem Studio and ADMET Predictor/ADMET Modeler operate in a more competitive environment. Several other companies presently offer simulation or modeling software, or simulation-software-based services, to the pharmaceutical industry.

Major pharmaceutical companies conduct drug discovery and development efforts through their internal development staffs and through outsourcing some of this work. Smaller companies need to outsource a greater percentage of this research. Thus, we compete not only with other software suppliers, but also with the in-house development teams at some of the larger pharmaceutical companies.

Although competitive products exist, both new licenses and license renewals for GastroPlus have continued to grow in spite of this competition. We believe that we enjoy a dominant market share in this segment.

We believe the key factors in competing in this field are our ability to develop industry-leading simulation and modeling software and related products and services to effectively predict activities and ADMET-related behaviors of new drug-like compounds, to design new molecules with acceptable activity and ADMET properties, to develop and maintain a proprietary database of results of physical experiments that will serve as a basis for simulated studies and empirical models, to attract and retain a highly skilled scientific and engineering team, and to develop and maintain relationships with research and development departments of pharmaceutical companies, universities and government agencies.

We are actively seeking acquisitions to expand the pharmaceutical software and services business. Earlier attempts to acquire other companies have not been successful either in arriving at mutually agreeable terms and conditions, or because of adverse conditions discovered during our comprehensive due diligence process.

WORDS+

PRODUCTS

Our wholly owned subsidiary, Words+, has been focused on introducing and improving augmentative and alternative communication and computer access software and devices for people with disabilities for over 30 years. The introduction of EyePro TM , an eyegaze product, in 2010 increased our revenue and marketshare. Eyegaze technology allows people to operate a computer or communication device by simply looking at the screen, and has been a major breakthrough for people with severe disabilities. In 2011, we added the EyePro GS to our eyegaze product line. The EyePro GS uses proprietary technology developed by Words+, where our other EyePro products use third party eyegaze technology that we bundle into our products. EyePro GS was released near the end of FY 2011. We also introduced the Conversa CV and CVX and upgraded most products to Windows 7. The Conversa is our line of tablet-based communication devices. The Conversa CV and CVX are based on Windows tablets with flip screens that allow them to convert between tablet and notebook formats.

MARKETING AND DISTRIBUTION

We market augmentative and alternative communication products through a network of employee representatives and independent dealers and resellers. Webinars and remote interaction using web-based evaluation, setup and training, introduced in 2009, have become standard parts of our operation. We have continued to see an increase in the number of family members, caregivers, teachers, and aides attending the live and recorded webinars. This is a significant change in the speech pathologist-to-patient relationship, and allows the speech pathologists’ professional experience and advice to extend beyond the therapy session to achieve more effective results for their clients. It has also allowed our sales force to spend less time training and more time selling, and allows us to recruit, train and support resellers who are less experienced in assistive technology.

We currently have 33 sales representatives worldwide: 1 salaried sales manager, 11 independent distributors and 6 independent resellers in the U.S., and 15 sales representatives overseas – 3 in Australia, and 1 each in New Zealand, Canada, The Netherlands, France, Ireland, Italy, Israel, Japan, Korea, Mexico, Malaysia, and Taiwan. We also have 3 inside support persons, who answer e-mails and telephone inquiries on our toll-free telephone line and who provide customer and technical support. Additional outside salespersons and independent dealers and resellers are being actively recruited.

We direct our marketing efforts to speech pathologists, occupational therapists, rehabilitation engineers, special education teachers, disabled persons and relatives of disabled persons. We maintain a mailing list of over 10,000 people made up of these professionals, consumers and relatives, and we mail various marketing materials to this list. These materials include our catalog of products and announcements regarding new and enhanced products.

We participate in industry conferences held worldwide that are attended by speech pathologists, occupational and physical therapists, special education teachers, parents and consumers. We and others in the industry demonstrate our products at these conferences and present technical papers that describe the application of our technologies and research studies on the effectiveness of our products. Words+ attended five major national conferences in 2011, and several more specialized national conferences, such as TEDPA (the national conference for specialized telecommunication equipment distribution program) and the American Occupational Therapist Association national conference. We responded to calls for papers and presented five different professional sessions during these conferences. We also advertise in selected publications and websites of interest to persons in this market.

We estimate that for approximately 62% of our sales of augmentative and alternative communication (“AAC”) software and hardware, purchases are funded primarily by third parties such as Medicaid, Medicare and private insurance. Telecommunication equipment distribution programs, school special education budgets, vocational rehabilitation, the Veterans Administration and other governmental programs, private purchases and charitable assistance account for most of the other purchases. Medicare provides coverage for augmentative communication devices.

Our personnel provide advice and assistance to customers and prospective customers on obtaining third-party financial assistance for purchasing our products. Third-party funding grew slowly for the first 20 years of operation; however, the addition of Medicare coverage for AAC devices in 2001 resulted in significant increases in third-party funding in recent years. Our Medicare/Medicaid and other third-party-funded sales have grown, with the majority of total sales are now funded by a third party. Medicare/Medicaid sales are subject to funding caps that limit the amounts paid for our products, and payment by some agencies can be slow, making this market segment somewhat more difficult than others. Collection of accounts receivable has been a significant problem from certain state Medicaid agencies, Medicaid, and private insurance. Our financial reporting includes allowances for bad debts that are based on assumptions that we will collect a historical percentage of accounts receivable that fall in different aging categories: less than 6 months, 6-12 months, 12-24 months, and over 24 months. Although we may not give up on any of the invoices that are included in the allowances for bad debts, we recognize that responsible financial reporting requires us to be conservative in these estimates.

PRODUCTION

Disability software products are either loaded onto computer hard disk drives by our employees or copied to CD-ROM or memory cards. Most software customers also buy their notebook personal computers from us, which we purchase at wholesale prices and resell at a markup. We purchase microprocessors that are part of dedicated devices such as MessageMates™. We design our cases, printed circuit boards, labels and other components of products such as SAM Communicator™ and our popular Conversa™ Sound Pack. We outsource the extrusion, machining and manufacturing of certain components. All final assembly and testing operations are done by our employees at our facility.

Our products are shipped from our Lancaster, California facility either directly to the customer or to the salesperson, dealer or reseller. Historically for major products, the outside salesperson, dealer or reseller either delivers the product or visits the customer after delivery to provide training. In our remote interactive sales and delivery model, an increasing number of deliveries are being completed utilizing internet with video support for setup, and webinars plus individual live video interaction for training.

COMPETITION

The AAC industry in which we operate is highly competitive and some of our competitors have greater financial and personnel resources than ours. The industry is made up of about six major competitors including Words+, and a number of smaller ones. Following the introduction of EyePro and other products to complement our current catalog, we are now focused on developing new products in-house.

We believe that the competition in this industry is based primarily on the quality of products, quality of customer training and technical support, and quality and size of sales forces. Price is a competitive factor that has traditionally not been as important to the purchaser or recommender as obtaining the product most suited to the customer’s needs, along with strong after-sale support. However, there has been significant downward pricing pressure due to the increasing popularity of extremely low-priced communication apps available on the popular Apple iPod and iPad, particularly in the past year. This is a change in our industry leading to a new category of low-cost technology, private payers, different service delivery expectations, and adverse affects on some traditional purchasers such as schools. To meet this challenge, we have been exploring lower cost solutions that compete in the iPod and iPad space, and different pricing and payment options to add to the cost-cutting, web-based remote delivery, training and support services we began in 2009. This remains a significant challenge and opportunity for us that we will continue to focus on.

We believe that we are a leader in the industry in developing and producing some of the most technologically advanced products and in providing quality customer training and technical support. We believe that the potential exists for significant increases in the sales of our disability products; however, there are few barriers to entry in the form of proprietary or patented technology or trade secrets in this industry. While we believe that cost of product development and the need for specialized knowledge and experience in this industry would present some barrier to entry for new competition, other companies may enter this industry, including companies with substantially greater financial resources than ours. Furthermore, companies already in this industry may increase their market share through increased technology development and marketing efforts.

TRAINING AND TECHNICAL SUPPORT

Customer training and technical support are important factors in customer satisfaction for both our pharmaceutical and disability products, and we believe we are an industry leader in providing customer training and technical support in both of our business areas. For pharmaceutical software, we provide in-house seminars at customers’ sites. These seminars often serve as initial training in the event the potential customer decides to license or evaluate our software. Technical support is provided after the sale in the form of on-site training (at customer’s expense), web meeting, telephone, fax, and e-mail assistance to users during the customer's license period. We have used Internet meetings extensively to provide demonstrations and customer assistance, resulting in rapid response to requests worldwide and reducing our travel time and expenses.

For disability products, our salesperson, dealer or reseller historically provided initial training to the customer for major systems -- typically two to four hours. This training is typically provided not only to the user of the product but also to speech pathologists, occupational therapists, rehabilitation engineers, teachers, parents and others who will assist the user. This initial training for the purchase of full systems is often provided as a part of the price of the product. Additional training and service calls are available for a fee. Live and recorded webinars introduced last year have significantly changed our service delivery model, making it more accessible to people who need training, and reducing the amount of time our sales force spends traveling and providing on-site, one-on-one training and support. Our salespeople still visit in person whenever appropriate, but the professional on-line training and support have greatly reduced this need. Feedback from surveys and increasing webinar attendance indicate improved customer satisfaction with our products and service delivery. The remote service delivery model that we have already implemented is becoming an expectation in our industry.

Technical support for both pharmaceutical software and disability products is provided by our life sciences team and our inside sales and support staff based at our headquarters facilities in Lancaster, California. We provide free telephone support offering unlimited toll-free numbers in the U.S. and Canada, and e-mail and web-based support for all of our pharmaceutical software and disability products worldwide. Technical support for pharmaceutical software products is minimal, averaging a few person-hours per month. Technical support for Words+ products varies from none for most customers to as much as several hours for others.

RESEARCH AND DEVELOPMENT

We believe that our ability to grow and remain competitive in our markets is strongly dependent on significant investment into research and development (“R&D”). R&D activities include both enhancement of existing products and development of new products. Development of new products and adding functionality to existing products are capitalized in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 985-20. R&D expenditures were approximately $1,846,000 during fiscal year 2011, of which $911,000 was capitalized. R&D expenditures during fiscal year 2010 were approximately $1,857,000, of which $887,000 was capitalized.

Our pharmaceutical business R&D activities during fiscal year 2011 were focused on improving our ADMET Predictor/ADMET Modeler, MedChem Studio, MedChem Designer and GastroPlus products.

Our R&D activities for our Words+ subsidiary were focused on development of our new EyePro GS eye gaze product line, extension of the family of tablet-computer-based systems called Conversa, and two new hardware development projects that we are not ready to announce at this time.

EMPLOYEES

As of August 31, 2011, we employed 38 full-time and 1 part-time employees, including 20 in research and development, 5 in marketing and sales, 8 in administration and accounting and 6 in production. Currently 16 employees hold Ph.D.s and 1 is a Ph.D. candidate in their respective science or engineering disciplines. Additionally, 3 employees hold one or more Master’s degrees. Most of the senior management team and Board of Directors hold graduate degrees. We believe that our future success will depend, in part, on our ability to continue to attract, hire and retain qualified personnel. The competition for such personnel in the pharmaceutical industry and in the augmentative and alternative communication device and computer software industry is intense. None of our employees is represented by a labor union, and we have never experienced a work stoppage. We believe that our relations with our employees are good. As noted earlier, we have signed an agreement to sell our Words+ subsidiary and expect to complete the transaction by November 30, 2011. After that date, assuming the transaction is completed, our number of employees will be reduced to approximately 25, of which all but four have advanced degrees. We continue to seek additions to our Life Sciences team.

PATENTS

We own two patents that were acquired as part of our acquisition of certain assets of Bioreason, Inc. We primarily protect our intellectual property through copyrights and trade secrecy. Our intellectual property consists primarily of source code for computer programs and data files for various applications of those programs in both the pharmaceutical software and the disability products businesses. In the disability products business, electronic device schematics, mechanical drawings, and design details are also intellectual property. The expertise of our technical staff is a considerable asset closely related to intellectual property, and attracting and retaining highly qualified scientists and engineers is essential to our business.

EFFECT OF GOVERNMENT REGULATIONS

Our pharmaceutical software products are tools used in research and development and are neither approved nor approvable by the FDA or other government agencies.

Most of our Words+ products for the disabled are funded by Medicare or Medicaid, schools, the Veteran’s Administration, and other insurance programs. Changes in government regulations regarding the allowability of augmentative communication aids and other assistive technology under such funding could affect our business; however, as noted earlier, Words+ is expected to be sold by November 30, 2011.

Costs and Effects of Compliance with Environmental Laws

Federal, state and local laws and regulations regarding the discharge of harmful materials into the environment may have an impact on the Company. Words+ is involved in manufacturing of Augmentative Communication Devises which uses laptop computers, and minor electronic assembly that might have a material adverse effect on the environment. However, the Company's exposure to environmental laws is not expected to be any more significant than any other similar type of business. Any new laws or regulations with regard to the environment that affect businesses in general are likely to result in additional compliance costs, and could result in additional operating restrictions. These costs could affect our future business operations. Words+ incurred environmental fee of $288 and $292 in FY11 and FY10, respectively, and electronic waste recycling fee of $466 and $16 in FY11 and FY10, respectively.

ITEM 1A – RISK FACTORS

Not applicable because the Company is a smaller reporting company.

ITEM 1B – UNRESOLVED STAFF COMMENTS

Not applicable.

ITEM 2 –PROPERTIES

We lease approximately 13,500 square feet of space in Lancaster, California. The original agreement had a five-year term with two (2), three-(3) year options to extend. Since the original five-year term expired in February 2011, we have exercised the first of the two (2), three-year options. The base rent started at the rate of $18,445 per month plus common area maintenance fees. The base rental rate increases at 4% annually and currently it is $21,578 per month, plus common area maintenance fees. We believe that this facility is sufficient for our current needs and growth for the foreseeable future.

In connection with the sale of our Words+ subsidiary to Prentke Romich Company, we expect to temporarily lease a portion of this space to PRC on a prorated basis. After January 1, 2012, we expect that portion to be reduced, providing additional room for growth of the Simulations Plus staff, which has been reaching its limits within the space available prior to the pending sale of Words+.

ITEM 5 – MARKET FOR REGISTRANT’S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our Common Stock is currently traded on the NASDAQ Stock Market (NASDAQ) under the symbol “SLP”. According to the records of our transfer agent, we had approximately 56 shareholders of record and approximately 1,540 beneficial owners as of August 31, 2011. The following table sets forth the low and high sale prices for our Common Stock as listed on the NASDAQ for the last two fiscal years. We have not paid cash dividends on our Common Stock to date. Any determination as to the payment of dividends will be at the discretion of our Board of Directors and will depend among other things, on our financial condition, results of operations, capital requirements and such other factors as the Board of Directors deems relevant.

On October 23, 2008, our board of directors authorized a share repurchase program enabling the buyback of up to $2.5 million in shares during a 12-month period beginning Monday, October 27, 2008. The actual repurchase started on December 2, 2008; therefore the board of directors extended it through December 1, 2009 in order to have a full 12-month period. The Company opened an account with Morgan Stanley Smith Barney for the purchase of such securities. Funds for any stock purchases are drawn from the Company’s cash reserves. The Company repurchased 1,026,483 shares at an average price of $1.3823 per share prior to December 1, 2009.

On January 10, 2010, the board of directors authorized a second share repurchase program (Phase II) effective as of February 15, 2010. The renewed program enabled the Company to buy back up to one million shares during a 12-month period. Under the Phase II program, the Company has purchased 996,248 shares at an average price of $2.8041 per share from April 2010 to February 2011.

There is currently no share repurchase program pending, and the Company made no repurchases of its securities within the fourth quarter of the fiscal year covered by this report.

ITEM 7 – MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the Consolidated Financial Statements and related notes included in this Annual Report on Form 10-K.

Management Overview

Fiscal year 2011 was a record year comprised of three record quarters. We believe the continued growth of our pharmaceutical software and services business segment is the result of increasing adoption of simulation and modeling software tools such as those we produce, as well as the expertise we offer as consultants to assist companies involved in the research and development of new medicines, which has resulted in a continuing series of study contracts with pharmaceutical companies ranging from several of the largest in the world to a number of medium-sized and smaller companies in the U.S. and Europe.

During FY11 we released major upgrades to three of our four pharmaceutical software offerings, and a new software product called MedChem Designer. Our financial performance enabled us to continue to increase our cash deposits, remain debt-free, and continue to invest in the aggressive marketing and sales activities we began in early 2009 in order to reach a wider customer base.

We have not been successful in identifying and completing any acquisitions during this reporting period in spite of a number of investigations and due diligence activities. In every case, either our due diligence activities revealed undesirable aspects of the potential acquisition, or terms and conditions agreeable to both sides were not able to be reached. It is our intent to continue to search for acquisition opportunities that would be compatible with our current businesses and that would be immediately accretive, i.e., adding to both revenues and earnings.

We have used some of our cash to repurchase shares of our common stock because we believe that reducing the number of fully diluted shares provides greater value to our shareholders than receiving a low interest rate on our cash deposits, and because we believe that our cash deposits after such repurchases remain sufficient to accomplish any reasonable potential acquisitions as well as to maintain sufficient cash reserves to ensure meeting operational needs for the foreseeable future. Although there are no stock repurchase programs pending, the board of directors may consider additional repurchases at any time at prices and under conditions set by the board.

Our Words+ subsidiary’s net income increased despite of the decline in sales due to reducing expenses. We developed and released our own new EyePro eyegaze system in August 2011; however, the continued poorer performance of this business unit caused us to agree to sell Words+ in November 2011, as previously discussed.

If the sale of Words+ is closed in November 2011, its net sales and income will be reported as discontinued operations going forward. The net sales and income for the last 3 years of Words+ operations are followings.

	Net Sales		Net Income (or loss)
FY09	$	2,842,000	$	(87,000	)
FY10		3,091,000		(82,000	)

FY11 COMPARED WITH FY10

Net Sales

Consolidated net sales increased $1,008,000, or 9.4%, to $11,720,000 in FY11 from $10,712,000 in FY10. Sales from pharmaceutical software and services increased approximately $1,118,000, or 14.7%; while Words+’s sales decreased approximately $110,000, or 3.6%, for the year. We attribute the increase in pharmaceutical software sales to increases in the number of licenses with new and existing customers, as well as licensing of new modules to existing customers. In addition, we generated revenue from workshop programs which we started in FY11. Those increases outweighed the decreases in revenue from funded collaborations and analytical studies (large collaboration contacts were completed by August 2010) and Grant (2-year grant from NIH ended at March 2011). We attribute the decrease in Words+ sales to a decline in sales of the “Say-it SAM!” handheld communicator competing against cheaper iPhone and iPad products which fit under the funding cap of some agencies, and to a decline in sales of hardware products. Decreased revenue from these products outweighed increases in revenue from our Freedom2000, “Conversa”, and our new EyePro products.

Cost of Sales

Consolidated cost of sales increased $333,000, or 13.1%, to $2,879,000 in FY11 from $2,546,000 in FY10. As a percentage of revenue, cost of sales also increased by 0.8%. For pharmaceutical software and services, cost of sales increased $286,000, or 23.6%, and as a percentage of revenue, it also increased to 17.1% in FY11 from 15.9% in FY10. A significant portion of cost of sales for pharmaceutical software products is the systematic amortization of capitalized software development costs, which is an independent fixed cost rather than a variable cost related to sales. This amortization cost increased approximately $64,000, or 11%, in FY11 compared with FY10. Royalty expense, another significant portion of cost of sales, increased approximately $134,000, or 30%, and Salary for analytical study increased approximately 88,000, or 50%, in FY11 compared with FY10. We pay a royalty on GastroPlus basic software sales but not on its optional modules. We also pay royalties on the Enslein Metabolism Module in our ADMET Predictor software in accordance with our agreement with Enslein Research, Inc.

For Words+, cost of sales increased $47,000, or 3.6%, and as a percentage of revenue, cost of sales also increased to 46.3% in FY11 from 43.1% in FY10.

Consolidated gross profit increased $675,000, or 8.3%, to $8,841,000 in FY11 from $8,166,000 in FY10. We attribute this increase to increased sales of pharmaceutical software and services which outweighed the decline in gross profit from Words+ operations.

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses for FY11 decreased by $20,000, or 0.5%, to $4,305,000, compared to $4,325,000 for FY10. As a percentage of sales, SG&A expenses decreased to 36.7% in FY11 from 40.4% in FY10. For Simulations Plus, SG&A expenses increased $273,000, or 10.6%. As a percentage of sales, SG&A for Simulations Plus decreased to 32.5% from 33.7%. The major increases in expenses were sales commissions as revenue from Japan and China increased, bonus expense paid to our CEO per his employment agreement, consulting fees, cost associated with stock repurchases, and payroll with payroll-related expenses, such as health/dental insurances and payroll taxes which outweighed the decrease in professional fees.

For Words+, expenses decreased by $293,000, or 16.7% due to decreases in allowances for bad debts.

Research and Development

We incurred approximately $1,846,000 of research and development (“R&D”) costs during FY11. Of this amount, $911,000 was capitalized and $935,000 was expensed as R&D. As we record hours spent for studies, $262,000 was expensed as cost of sales. During FY10, we incurred approximately $1,857,000 of research and development costs, of which approximately $887,000 was capitalized and approximately $970,000 was expensed. The hours spent for studies during FY10 expensed as cost of sales amounted to $175,000. The 0.6% decrease in research and development expenditure from FY10 to FY11 was due to an increase in hours spent on analytical studies, which reduced hours available for R&D activities.

Income from operations

During FY11, we generated income from operations of $3,601,000, as compared to $2,871,000 for FY10, an increase of 25.4%. We attribute this increase to increases in gross profit from pharmaceutical software and study contract services and decreases in SG&A expense and R&D expenses.

Other Income and (Expense)

The net of other income over other expense for FY11 decreased by $64,000, or 27.6%, to $169,000, compared to $233,000 for FY10, due to changes in the currency exchange rate for Japanese Yen caused by the weaker U.S. dollar.

Provision for Income Taxes

Provision for income taxes for FY11 increased by $107,000, or 11.3%, to $1,055,000, compared to $948,000 for FY10 due to the increase in net income. The tax rate used in this report is lower than the standard rate because of various tax credits generated during this reporting period.

Net Income

Net income for FY11 increased by $559,000, or 25.9%, to $2,715,000, compared to $2,156,000 for FY10. We attribute this increase in net income to increased gross profit, decreases in SG&A and R&D expenses, which outweighed decreases in other income and an increase in taxes.

SEASONALITY

Sales in the pharmaceutical products and services business segment (“Simulations Plus” in the table below) exhibit some seasonal fluctuations, with the fourth fiscal quarter (June-August) generally having the lowest sales over the past three fiscal years because of summer vacations and reduced activities at our customers’ sites. This unaudited net sales information has been prepared on the same basis as the annual information presented elsewhere in this Annual Report on Form 10-K and, in the opinion of management, reflects all adjustments (consisting of normal recurring entries) necessary for a fair presentation of the information presented. Net sales for any quarter are not necessarily indicative of sales for any future period; however, because our pharmaceutical software is licensed on an annual basis, renewals are almost always within the same quarter year after year.

LIQUIDITY AND CAPITAL RESOURCES

Our principal source of capital has been cash flow from our operations. We have achieved continuous positive operating cash flow over the last nine fiscal years. We believe that our existing capital and anticipated funds from operations will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for the foreseeable future. Thereafter, if cash generated from operations is insufficient to satisfy our capital requirements, we may open a revolving line of credit with a bank, or we may have to sell additional equity or debt securities or obtain expanded credit facilities. In the event such financing is needed in the future, there can be no assurance that such financing will be available to us, or, if available, that it will be in amounts and on terms acceptable to us. If cash flows from operations become insufficient to continue operations at the current level, and if no additional financing was obtained, then management would restructure the Company in a way to preserve its pharmaceutical business while maintaining expenses within operating cash flows.

We are not aware of any trends or demands, commitments, or uncertainties that are reasonably likely to result in a decrease in liquidity of our assets. The trend over the last nine years has been increasing cash deposits from our operating cash flows, and we expect that trend to continue for the foreseeable future. We have no material commitments for capital expenditures as of the end of the latest fiscal period.

We continue to seek opportunities for strategic acquisitions. If one or more such acquisition is identified, a substantial portion of our cash reserves may be required to complete it; however, we intend to maintain sufficient cash reserves after any acquisition to provide reasonable assurance that outside financing will not be necessary to continue operations. If we identify an attractive acquisition that would require more cash to complete than we are willing or able to use from our cash reserves, we will consider financing options to complete the acquisition, including obtaining loans and issuing additional securities.

UNUSUAL OR INFREQUENT EVENTS

There have been no unusual or infrequent events or other significant economic changes that have affected reported income, however, income may be impacted in the future by the sale of our Words+ subsidiary.

KNOWN TRENDS OR UNCERTAINTIES

We are not aware of any trends or uncertainties expected to impact net sales or revenues from the operations of our pharmaceutical business segment. The recent trend toward consolidation in the pharmaceutical industry has not had a negative effect on our sales to that industry, and we believe that the need for improved productivity in the research and development activities directed toward developing new medicines will continue to result in increasing adoption of simulation and modeling tools such as those we produce.

New product developments in the pharmaceutical business segments could result in increased revenues and earnings if they are accepted by our markets; however, there can be no assurances that new products will result in significant improvements to revenues or earnings. For competitive reasons, we do not disclose all of our new product development activities.

Our continued quest for acquisitions in the pharmaceutical business segment could result in a significant change to revenues and earnings if one or more such acquisitions are completed. It is our intent to only complete acquisitions that would add to both revenues and earnings; however, there can be no assurances that any acquisitions that may be completed will in fact result in both increased revenues and earnings.

We entered into a Stock Purchase Agreement with Prentke Romich Company (PRC) to sell all of the stock of Words+ to PRC for $2.1 million, subject to adjustments for changes in net working capital. The full text of this agreement was filed as Exhibit 10.1 in Form 8-K on November 16, 2011 and is incorporated by reference. If this transaction is closed, then the Words+ business segment will be reported as discontinued operations.

INFLATION

We have not been affected materially by inflation during the periods presented, and no material effect is expected in the near future.

OFF-BALANCE SHEET ARRANGEMENTS

As of August 31, 2011, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

We do not have relationships or transactions with persons or entities that derive benefits from their non-independent relationship with us or our related parties.

RECENTLY ISSUED ACCOUNTING STANDARDS

In September 2009, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2009-14 which amends Statement of Position (“SOP”) 97-2, “Software Revenue Recognition”, to exclude tangible products containing software components and non-software components that function together to deliver the product’s essential functionality. ASU 2009-14 applies to revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, with early application permitted with Emerging Issues Task Force (“EITF”) 08-1. We adopted this standard in the first quarter of fiscal 2011. We believe adoption did not have a material effect on the Company’s consolidated financial statements.

In September 2009, the FASB issued ASU 2009-13, “Revenue Arrangements with Multiple Deliverables” (“EITF 08-1”). ASU 2009-13 amends EITF 00-21, “Revenue Arrangements with Multiple Deliverables”, to require an entity to use an estimated selling price when vendor-specific objective evidence or acceptable third-party evidence does not exist for any products or services included in a multiple element arrangement. The arrangement consideration should be allocated among the products and services based upon their relative selling prices, thus eliminating the use of the residual method of allocation. ASU 2009-13 also requires expanded qualitative and quantitative disclosures regarding significant judgments made and changes in applying the guidance. ASU 2009-13 applies to fiscal years beginning after June 15, 2010, with early application permitted. We adopted ASU 2009-13 in June 2011. We believe adoption did not have a material effect on the Company’s consolidated financial statements.

CRITICAL ACCOUNTING POLICIES

Our consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. These estimates and assumptions are affected by management’s application of accounting policies. Critical accounting policies for us include revenue recognition, accounting for capitalized software development costs, and accounting for income taxes.

Revenue Recognition

We recognize revenue related to software licenses and software maintenance in accordance with the FASB Accounting Standard Codification (“ASC”) 985-605. Product revenue is recorded when the following conditions are met: 1) evidence of arrangement exists, such as signed purchase orders from customers or executed contracts, 2) delivery has been made, such as unlocking the software on the customer’s computer(s), 3) the amount is fixed, and 4) it is collectible. Post-contract customer support ("PCS") obligations are insignificant; therefore, revenue for PCS is recognized at the same time, and the costs of providing such support services are accrued and amortized over the obligation period.

As a byproduct of ongoing improvements and upgrades to our software, some modifications are provided to customers who have already licensed software during their license term at no additional charge. We consider these modifications to be minimal, as they are not changing the basic functionality or utility of the software, but rather adding convenience, such as being able to plot some additional variable on a graph in addition to the numerous variables that had been available before. Such software modifications for any single product have been typically once or twice per year, sometimes more, sometimes less. Thus, they are infrequent. We provide, for a fee, additional training and service calls to our customers and recognize revenue at the time the training or service call is provided.

We enter into one-year license agreements with most of our customers for the use of our pharmaceutical software products. However, from time to time, we enter into multi-year license agreements. We unlock and invoice software one year at a time for multi-year licenses. Therefore, revenue is recognized one year at a time.

We recognize contract study revenue either equally over the term of the contract or using the percentage of completion method, depending upon how the contract studies are engaged, in accordance with FASB ASC 605-35. To recognize revenue using the percentage of completion method, we must determine whether we meet the following criteria: 1) there is a long-term, legally enforceable contract, 2) it is possible to reasonably estimate the total project costs, and 3) it is possible to reasonably estimate the extent of progress toward completion.

Capitalized Computer Software Development Costs

Software development costs are capitalized in accordance with FASB ASC 985-20. Capitalization of software development costs begins upon the establishment of technological feasibility and is discontinued when the product is available for sale.

The establishment of technological feasibility and the ongoing assessment for recoverability of capitalized software development costs require considerable judgment by management with respect to certain external factors including, but not limited to, technological feasibility, anticipated future gross revenues, estimated economic life, and changes in software and hardware technologies. Capitalized software development costs are comprised primarily of salaries and direct payroll-related costs and the purchase of existing software to be used in our software products.

Amortization of capitalized software development costs is provided on a product-by-product basis on the straight-line method over the estimated economic life of the products (not to exceed five years). Amortization of software development costs amounted to $688,651 and $644,015 for the fiscal years ended August 31, 2011 and 2010, respectively. We expect future amortization expense to vary due to increases in capitalized computer software development costs.

We test capitalized computer software costs for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable within a reasonable time.

Income Taxes

We utilize FASB ASC 740-10 which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns.

Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each year-end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. The provision for income taxes represents the tax payable for the period and the change during the period in deferred tax assets and liabilities.

Stock-Based Compensation

The Company accounts for stock options using the modified prospective method in accordance with FASB ASC 718-10 . Under this method, compensation costs include: (1) compensation cost for all share-based payments granted prior to, but not yet vested as of September 1, 2006, based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123 amortized over the options’ vesting period, and (2) compensation cost for all share-based payments granted subsequent to September 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of FASB ASC 718-10 , amortized on a straight-line basis over the options’ vesting period. Stock-based compensation was $155,252 and $127,597 for the years ended August 31, 2011 and 2010, respectively, and is included in the consolidated statements of operations as Consulting, Salaries, and Research and Development expense.

Principles of Consolidation

The consolidated financial statements include the accounts of Simulations Plus, Inc. and its wholly owned subsidiary, Words+, Inc. All significant intercompany accounts and transactions are eliminated in consolidation.

Estimates

Our consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. These estimates and assumptions are affected by management’s application of accounting policies. Actual results could differ from those estimates. Significant accounting policies for us include revenue recognition, accounting for capitalized software development costs, and accounting for income taxes.

Not applicable because the Company is a smaller reporting company.

ITEM 8 - FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

The responses to this item are included elsewhere in this Form 10-K (see pages F1 – F23) and incorporated herein by reference.

ITEM 9 – CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

There have been no changes to our public accountants during the past two years.

ITEM 9A – CONTROLS AND PROCEDURES

We are responsible for maintaining disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Disclosure controls and procedures are controls and other procedures designed to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer) of our disclosure controls and procedures as required by Rule 13a-15 under the Exchange Act, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of August 31, 2011, the end of the fiscal year covered by this report.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting, as defined in Exchange Act Rule 13a-15(f). Our internal controls over financial reporting are designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal controls over financial reporting based on the framework established by the Committee of Sponsoring Organizations for the Treadway Commission. Based on our evaluation under the framework, including the completion and review of internal review assessment forms and the completion and review of financial reporting information systems and controls checklists in the framework, our management concluded that our internal control over financial reporting was effective as of August 31, 2011.

No changes were made in our internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Our management, including our CEO and CFO, does not expect that our disclosure controls or internal controls over financial reporting will prevent all errors or all instances of fraud. A control system, no matter how well-designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and any design may not succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitation of a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Simulations Plus, Inc.

Lancaster, California

We have audited the accompanying consolidated balance sheets of Simulations Plus, Inc. (a California corporation) and Subsidiary as of August 31, 2011 and 2010 and the related consolidated statements of operations, shareholders’ equity and cash flows for the years then ended. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards established by the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Simulation Plus, Inc. and Subsidiary as of August 31, 2011 and 2010, and the consolidated results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

August 31, 2011 and 2010

NOTE 1 - ORGANIZATION AND LINES OF BUSINESS

Organization

Simulations Plus, Inc. was incorporated on July 17, 1996. On August 29, 1996, the shareholders of Words+, Inc. exchanged their 2,000 shares of Words+, Inc. common stock for 2,200,000 (Pre-split) shares of Simulations Plus, Inc. common stock, and Words+, Inc. became a wholly owned subsidiary of Simulations Plus, Inc. (collectively, the "Company").

Lines of Business

The Company designs and develops pharmaceutical simulation software to promote cost-effective solutions to a number of problems in pharmaceutical research and in the education of pharmacy and medical students. The Company also develops and sells interactive, educational software programs that simulate science experiments conducted in middle school, high school, and junior college science classes as well as a productivity software program called Abbreviate! that was moved from the Words+ subsidiary to Simulations Plus. In addition, the Company’s subsidiary designs and develops computer software and manufactures augmentative communication devices and computer access products that provide a voice for those who cannot speak and allow physically disabled persons to operate a standard computer.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

Principles of Consolidation

Revenue Recognition

The Company recognizes revenues related to software licenses and software maintenance in accordance with the Financial Accounting Standard Board (“FASB”) Accounting Standard Codification (“ASC”) 985-605. Software products revenue is recorded when the following conditions are met: 1) evidence of arrangement exists, 2) delivery has been made, 3) the amount is fixed, and 4) collectability is probable. Post-contract customer support ("PCS") obligations are insignificant; therefore, revenue for PCS is recognized at the same time as the licensing fee, and the costs of providing such support services are accrued and amortized over the obligation period. For Words+ products, the revenue is recorded at the time of shipment, net of estimated allowances and returns.

SIMULATIONS PLUS, INC. AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

August 31, 2011 and 2010

As a byproduct of ongoing improvements and upgrades for the new programs and new modules of software, some modifications are provided to customers who have already purchased software at no additional charge. Other software modifications result in new, additional cost modules that expand the functionality of the software. These are licensed separately. We consider the modifications that are provided without charge to be minimal, as they do not significantly change the basic functionality or utility of the software, but rather add convenience, such as being able to plot some additional variable on a graph in addition to the numerous variables that had been available before, or adding some additional calculations to supplement the information provided from running the software. Such software modifications for any single product have typically occurred once or twice per year, sometimes more, sometimes less. Thus, they are infrequent. The Company provides, for a fee, additional training and service calls to its customers and recognizes revenue at the time the training or service call is provided.

Generally, we enter into one-year license agreements with customers for the use of our pharmaceutical software products. We recognize revenue on these contracts when all the criteria are met.

Most license agreements have a term of one year; however, from time to time, we enter into multi-year license agreements. We generally unlock and invoice software one year at a time for multi-year licenses. Therefore, revenue is recognized one year at a time.

We recognize the revenue from collaboration research and the revenue from grants equally over their terms. However, we recognize the contract study revenue using the percentage of completion method, depending upon how the contract studies are engaged, in accordance with FASB ASC 605-35. To recognize revenue using the percentage of completion method, we must determine whether we meet the following criteria: 1) there is a long-term, legally enforceable contract and 2) it is possible to reasonably estimate the total project costs, and 3) it is possible to reasonably estimate the extent of progress toward completion.

Cash and Cash Equivalents

For purposes of the statements of cash flows, the Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.

Accounts Receivable

The Company maintains an allowance for doubtful accounts for estimated losses that may arise if any of its customers are unable to make required payments. Management specifically analyzes the age of customer balances, historical bad debt experience, customer credit-worthiness, and changes in customer payment terms when making estimates of the collectibility of the Company’s trade accounts receivable balances. If the Company determines that the financial conditions of any of its customers deteriorated, whether due to customer-specific or general economic issues, an increase in the allowance may be made. Accounts receivable are written off when all collection attempts have failed. The Company also estimates the contractual discount obligation for third party funding such as Medicare, Medicaid, and private insurance companies. Those estimated discounts are reflected in the allowance for doubtful accounts and contractual discounts.

Inventory

Inventory is stated at the lower of cost (first-in, first-out basis) or market and consists primarily of computers and peripheral computer equipment.

Capitalized Computer Software Development Costs

The establishment of technological feasibility and the ongoing assessment for recoverability of capitalized software development costs require considerable judgment by management with respect to certain external factors including, but not limited to, technological feasibility, anticipated future gross revenues, estimated economic life, and changes in software and hardware technologies. Capitalized computer software development costs are comprised primarily of salaries and direct payroll-related costs and the purchase of existing software to be used in the Company's software products.

Amortization of capitalized computer software development costs is provided on a product-by-product basis on the straight-line method over the estimated economic life of the products (not to exceed five years). Amortization of software development costs amounted to $688,651 and $644,015 for the years ended August 31, 2011 and 2010, respectively. We expect future amortization expense to vary due to increases in capitalized computer software development costs.

Management tests capitalized computer software development costs for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Property and Equipment

Property and equipment are recorded at cost, less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over the estimated useful lives as follows:

Equipment 5 years

Computer equipment 3 to 7 years

Furniture and fixtures 5 to 7 years

Leasehold improvementsShorter of life of asset or lease

Maintenance and minor replacements are charged to expense as incurred. Gains and losses on disposals are included in the results of operations.

Fair Value of Financial Instruments

A ssets and liabilities recorded at fair value in the Consolidated Balance Sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. The categories, as defined by the standard, are as follows:

Level Input:		Input Definition:
Level I		Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date.
Level II		Inputs, other than quoted prices included in Level I, that are observable for the asset or liability through corroboration with market data at the measurement date.
Level III		Unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date.

The following table summarizes fair value measurements by level at August 31, 2011 for assets and liabilities measured at fair value on a recurring basis:

	Level I		Level II	Level III	Total

Cash and cash equivalents	$	10,181,049	$	$	$	10,181,049

Total assets	$	10,181,049	$	$	$	10,181,049

Advertising

The Company expenses advertising costs as incurred. Advertising costs for the years ended August 31, 2011 and 2010 were $39,000 and $40,000, respectively.

Shipping and Handling

Shipping and handling costs are recorded as cost of sales and amounted to $77,000 and $114,000 for the years ended August 31, 2011 and 2010, respectively.

Research and Development Costs

Research and development costs are charged to expense as incurred until technological feasibility has been established. These costs consist primarily of salaries and direct payroll-related costs. It also includes purchased software which was developed by other companies and incorporated into, or used in the development of, our final products.

Income Taxes

The Company utilizes FASB ASC 740-10 which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

August 31, 2011 and 2010

Earnings per Share

The Company reports earnings per share in accordance with FASB ACS 260-10. Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of common shares available. Diluted earnings per share is computed similarly to basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. The components of basic and diluted earnings per share for the years ended August 31, 2011 and 2010 were as follows:

	2011		2010

Net income attributable to common shareholders	$	2,714,641	$	2,156,073

Common stock and common stock equivalents used for diluted earnings per share		16,082,454		16,513,018

Stock-Based Compensation

The Company accounts for stock options using the modified prospective method in accordance with FASB ACS 718-10. Under this method, compensation costs include: (1) compensation cost for all share-based payments granted prior to, but not yet vested as of September 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of Statement of Financial Accounting Standard (“SFAS”) No. 123 amortized over the options’ vesting period, and (2) compensation cost for all share-based payments granted subsequent to September 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of SFAS No. 123R, amortized on a straight-line basis over the options’ vesting period. Stock-based compensation was $155,252 and $127,597 for the years ended August 31, 2011 and 2010, respectively, and is included in the consolidated statements of operations as Consulting, Salaries, and Research and Development expense.

Concentrations and Uncertainties

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents and trade accounts receivable. The Company holds cash and cash equivalents at banks located in California, with balances that often exceed FDIC insured limits. Historically, the Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents. However, considering the current banking environment, the Company is investigating alternative ways to minimize its exposure to such risks. While the Company may be exposed to credit losses due to the nonperformance of its counterparties, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows or financial condition.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

August 31, 2011 and 2010

International sales accounted for 36% and 34% of net sales for the years ended August 31, 2011 and 2010, respectively. For Simulations Plus, Inc. (pharmaceutical segment), three customers accounted for 11% (one is a dealer account representing various customers), 8% and 7% of net sales for the year ended August 31, 2011. For the year ended August 31, 2010, two customers accounted for 12% (one is a dealer account representing various customers) and 11% of net sales.

For Words+, Inc., third-party billing, which includes various government agencies as well as private insurance companies, accounted for 62% and 65% of net sales for the years ended August 31, 2011 and 2010, respectively. If changes are made in government funding policies for Words+ products, Words+ revenue may be impacted. We continually evaluate and monitor regulatory developments in funding matters, and we do not expect Medicare and Medicaid of all 50 states to discontinue their funding of Words+ products; however, there can be no assurances that the current level of revenue from third parties will continue.

We operate in the computer software industry, which is highly competitive and changes rapidly. Our operating results could be significantly affected by our ability to develop new products and find new distribution channels for new and existing products.

For Simulations Plus (pharmaceutical segment), two customers comprised 36% (a dealer account representing various customers) and 18% of accounts receivable at August 31, 2011, and two customers comprised 43% (one is a dealer account representing various customers) and 16% of accounts receivable at August 31, 2010. For Words+, third-party billing, which includes various government agencies, comprised 86% of its accounts receivable at August 31, 2011 and 84% of its accounts receivable at August 31, 2010. Collection of those accounts receivable in a timely manner is critical in Words+’ cash flow and its operations. We have three dedicated funding/billing personnel who continually track such collections.

The Company’s subsidiary, Words+, Inc., purchases components for the main computer products from three manufacturers. Words+, Inc. also uses a number of pictographic symbols that are used in its software products which are licensed from a third party. The inability of the Company to obtain computers used in its products or to renew its licensing agreement to use pictographic symbols could negatively impact the Company's financial position, results of operations, and cash flows.

Recently Issued Accounting Standards

In September 2009, the FASB issued ASU 2009-14 which amends Statement of Position (“SOP”) 97-2, “Software Revenue Recognition”, to exclude tangible products containing software components and non-software components that function together to deliver the product’s essential functionality. ASU 2009-14 applies to revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, with early application permitted with EITF 08-1. We expect to adopt this standard in the first quarter of fiscal 2011. We adopted this standard in the first quarter of fiscal 2011. We believe adoption did not have a material effect on the Company’s consolidated financial statements.

In September 2009, the FASB issued ASU 2009-13, “Revenue Arrangements with Multiple Deliverables” (“EITF 08-1”). ASU 2009-13 amends EITF 00-21, “Revenue Arrangements with Multiple Deliverables”, to require an entity to use an estimated selling price when vendor-specific objective evidence or acceptable third-party evidence does not exist for any products or services included in a multiple element arrangement. The arrangement consideration should be allocated among the products and services based upon their relative selling prices, thus eliminating the use of the residual method of allocation. ASU 2009-13 also requires expanded qualitative and quantitative disclosures regarding significant judgments made and changes in applying the guidance. ASU 2009-13 applies to fiscal years beginning after June 15, 2010, with early application permitted. We expect to adopt this standard in the first quarter of fiscal 2011. We adopted ASU 2009-13 in June 2011. We believe adoption did not have a material effect on the Company’s consolidated financial statements.

NOTE 5 - SHAREHOLDERS' EQUITY

Stock Repurchase

On October 23, 2008, the Board of Directors authorized a share repurchase program (Phase I) enabling the buyback of up to $2.5 million in shares during a 12-month period beginning Monday, October 27, 2008. The actual repurchase started on December 2, 2008; therefore the Board of Directors extended it through December 1, 2009 in order to have a full 12-month period. We opened an account with Morgan Stanley Smith Barney for the purchase of such securities. Funds for any stock purchases are drawn from our cash reserves.

On January 10, 2010, the Board of Directors authorized a renewed share repurchase program (Phase II) effective as of February 15, 2010. The renewed program enabled the Company to buy back up to one million shares during a 12-month period.

The details of repurchases made under Phase I and Phase II are listed in the following table:

Stock Option Plan

In September 1996, the Board of Directors adopted, and the shareholders approved, the 1996 Stock Option Plan (the "Option Plan") under which a total of 1,000,000 shares of common stock had been reserved for issuance. In March 1999, the shareholders approved an increase in the number of shares that may be granted under the Option Plan to 2,000,000. In February 2000, the shareholders approved an increase in the number of shares that may be granted under the Option Plan to 4,000,000. In December 2000, the shareholders approved an increase in the number of shares that may be granted under the Option Plan to 5,000,000. Furthermore, in February 2005, the shareholders approved an additional 1,000,000 shares, resulting in the total number of shares that may be granted under the Option Plan to 6,000,000. The 1996 Stock Option Plan terminated in September 2006 by its term.

On February 23, 2007, the Board of Directors adopted and the shareholders approved the 2007 Stock Option Plan under which a total of 1,000,000 shares of common stock had been reserved for issuance.

The number of shares described above are adjusted reflecting the two-for-one stock splits on August 14, 2006 and October 1, 2007.

August 31, 2011 and 2010

The fair value of the options granted during the year ended August 31, 2011 is estimated at $57,384. The fair value of these options was estimated at the date of grant using the Black-Scholes option-pricing model with the following assumptions for the fiscal year ended August 31, 2011: dividend yield of 0%, pre-vest forfeiture rate of 2.32% to 40.71%, expected volatility of 54.71% to 79.91%, risk-free interest rate of 1.42% to 2.66%, and expected life of 4.0 years. The total fair value of non-vested stock options as of August 31, 2011 was $270,387 and is amortizable over a weighted average period of 2.18 years.

During the previous fiscal year ended August 31, 2010, the fair value of the options granted is estimated at $225,650. The assumptions were dividend yield of 0%, pre-vest forfeiture rate of 2.32% to 40.71%, expected volatility of 54.71% to 79.91%, risk-free interest rate of 0.43% to 2.35%, and expected life of 1.0 to 5.0 years. The total fair value of non-vested stock options as of August 31, 2010 was $509,478 and is amortizable over a weighted average period of 2.82 years.

During the years ended August 31, 2011 and 2010, the Company recognized an income tax benefit of $24,081 and $1,130,577 respectively, relating to stock-based compensation arrangements.

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which do not have vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Because the Company's employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options.

The weighted-average remaining contractual life of options outstanding issued under the Plan was 5.1 years at August 31, 2011. The exercise prices for the options outstanding at August 31, 2011 ranged from $0.26 to $3.27, and the information relating to these options is as follows:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

August 31, 2011 and 2010

The Company follows guidance issued by the FASB with regard to its accounting for uncertainty in income taxes recognized in the financial statements. Such guidance prescribes a recognition threshold of more likely than not and a measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. In making this assessment, a company must determine whether it is more likely than not that a tax position will be sustained upon examination, based solely on the technical merits of the position and must assume that the tax position will be examined by taxing authorities. Our policy is to include interest and penalties related to unrecognized tax benefits in income tax expense. Interest and penalties totaled $1,035 and $7,191 for the years ended August 31, 2011 and 2010, respectively. The Company files income tax returns with the Internal Revenue Service (“IRS”) and the state of California. For jurisdictions in which tax filings are prepared, the Company is no longer subject to income tax examinations by state tax authorities for years through 2005, and by the IRS for years through 2006. As of August 31, 2011, the Company’s tax returns for tax year ends August 31, 2007 and 2008 are under examination by the California Franchise Tax Board. The potential outcome of these examinations cannot be determined as of August 31, 2011. Our review of prior year tax positions using the criteria and provisions presented in guidance issued by FASB did not result in a material impact on the Company’s financial position or results of operations.
