The following securities were excluded from the weighted average dilutive common shares outstanding because their inclusion would have been antidilutive.

Common Stock Purchase Warrants and Other Derivative Financial Instruments

The Company classifies common stock purchase warrants and other free standing derivative financial instruments as equity if the contracts (i) require physical settlement or net-share settlement or (ii) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (ii) give the counterparty a choice of net cash settlement or settlement in shares (physical settlement or net-share settlement), or (iii) contain reset provisions as either an asset or a liability. The Company assesses classification of its freestanding derivatives at each reporting date to determine whether a change in classification between assets and liabilities is required. The Company determined that its freestanding derivatives, which principally consist of warrants to purchase common stock, satisfied the criteria for classification as equity instruments.

Revenue Recognition and Accounts Receivable

The Company generates revenue from sales of its products to a customer base including hospitals, medical centers, doctors, pharmacies, distributors and wholesalers. The Company sells products directly to end users and to distributors. The Company also entered into agreements to license its technology and products.

The Company also provides regulatory compliance testing and quality assurance services to medical device and pharmaceutical companies.

The Company records revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the fee is fixed or determinable, and (iv) collectability of the sale is reasonably assured.

The Company requires all product sales to be supported by evidence of a sale transaction that clearly indicates the selling price to the customer, shipping terms and payment terms. Evidence of an arrangement generally consists of a contract or purchase order approved by the customer. The Company has ongoing relationships with certain customers from which it customarily accepts orders by telephone in lieu of purchase orders.

The Company recognizes revenue at the time it receives confirmation that the goods were either tendered at their destination, when shipped “FOB destination,” or transferred to a shipping agent, when shipped “FOB shipping point.” Delivery to the customer is deemed to have occurred when the customer takes title to the product. Generally, title passes to the customer upon shipment, but could occur when the customer receives the product based on the terms of the agreement with the customer.

The selling prices of all goods are fixed, and agreed to with the customer, prior to shipment. Selling prices are generally based on established list prices. The right to return product is customarily based on the terms of the agreement with the customer. The Company estimates and accrues for potential returns and records this as a reduction of revenue in the same period the related revenue is recognized. Additionally, distribution fees are paid to certain wholesale distributors based on contractually determined rates. The Company estimates and accrues the fee on shipment to the respective wholesale distributors and recognizes the fee as a reduction of revenue in the same period the related revenue is recognized. The Company also offers cash discounts to certain customers, generally 2% of the sales price, as an incentive for prompt payment. The Company accounts for cash discounts by reducing accounts receivable by the prompt pay discount amount and recognizes the discount as a reduction of revenue in the same period the related revenue is recognized. Additionally, the Company participates in certain rebate programs which provide discounted prescriptions to qualified patients. The Company contracts with a third-party to administer the program. The Company estimates and accrues for future rebates based on historical data for rebate redemption rates and the historical value of redemptions. Rebates are recognized as a reduction of revenue in the same period the related revenue is recognized.

The Company evaluates the creditworthiness of new customers and monitors the creditworthiness of its existing customers to determine whether an event or changes in their financial circumstances would raise doubt as to the collectability of a sale at the time in which a sale is made. Payment terms on sales made in the United States are generally 30 to 60 days and are extended up to 90 days for initial product launches, payment terms internationally generally range from prepaid prior to shipment to 90 days.

In the event a sale is made to a customer under circumstances in which collectability is not reasonably assured, the Company either requires the customer to remit payment prior to shipment or defers recognition of the revenue until payment is received. The Company maintains a reserve for amounts which may not be collectible due to risk of credit losses.

In the event a sale is made to a customer under circumstances in which returns cannot be estimated, the Company defers recognition of the revenue until sell-through is confirmed.

Product license revenue is generated through agreements with strategic partners for the commercialization of Microcyn® products. The terms of the agreements sometimes include non-refundable upfront fees. The Company analyzes multiple element arrangements to determine whether the elements can be separated. Analysis is performed at the inception of the arrangement and as each product is delivered. If a product or service is not separable, the combined deliverables are accounted for as a single unit of accounting and recognized over the performance obligation period.

When appropriate, the Company defers recognition of non-refundable upfront fees. If the Company has continuing performance obligations then such up-front fees are deferred and recognized over the period of continuing involvement.

The Company recognizes royalty revenues from licensed products upon the sale of the related products.

Revenue from consulting contracts is recognized as services are provided. Revenue from testing contracts is recognized as tests are completed and a final report is sent to the customer.

Inventories

Inventories are stated at the lower of cost, cost being determined on a standard cost basis (which approximates actual cost on a first-in, first-out basis), or market.

Due to changing market conditions, estimated future requirements, age of the inventories on hand and production of new products, the Company regularly reviews inventory quantities on hand and records a provision to write down excess and obsolete inventory to its estimated net realizable value. The Company recorded reserves to reduce the carrying amounts of inventories to their net realizable value in the amounts of $183,000$191,000 and $164,000$61,000 at December 31, 2016September 30, 2017 and March 31, 2016.2017, respectively.

Income TaxesReclassifications

The Company is required to determine the aggregate amount of income tax expense or loss based upon tax statutes in jurisdictions in which it conducts business. In making these estimates, the Company adjusts its results determined in accordance with generally accepted accounting principles for items that are treated differently by the applicable taxing authorities. Deferred tax assets and liabilities resulting from these differences are reflected on its balance sheet for temporary differences in loss and credit carryforwards that will reverse in subsequent years. The Company also establishes a valuation allowance against deferred tax assets when it is more likely than not that some or all of the deferred tax assets will not be realized. Valuation allowances are based, in part, on predictions that management must make as to the results in future periods. The outcome of events could differ over time which would require that the Company makes changes in its valuation allowance.

Financial Assets and Liabilities

Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses and other liabilities are carried at cost, which management believes approximates fair value dueCertain prior period amounts have been reclassified for comparative purposes to conform to the short-term nature of these instruments. The fair value of capital lease obligations and equipment loans approximates their carrying amounts as a market rate of interest is attached to their repayment. The Company measures the fair value of financial assets and liabilities basedfiscal 2018 presentation. These reclassifications have no impact on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The Company uses three levels of inputs that may be used to measure fair value:Company’s previously reported condensed consolidated net loss.

Level 1 – quoted prices in active markets for identical assets or liabilities

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

Level 3 – inputs that are unobservable (for example cash flow modeling inputs based on assumptions)

Level 3 liabilities are valued using unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the liabilities. For fair value measurements categorized within Level 3 of the fair value hierarchy, the Company’s accounting and finance department, who report to the Chief Financial Officer, determine its valuation policies and procedures. The development and determination of the unobservable inputs for Level 3 fair value measurements and fair value calculations are the responsibility of the Company’s accounting and finance department and are approved by the Chief Financial Officer.

As of December 31, 2016 and March 31, 2016, there were no transfers in or out of Level 3 from other levels in the fair value hierarchy.

Adoption of Recent Accounting PronouncementsStandards

In January 2016, the FASB issued ASU 2016-01 Financial Instruments-Overall, which address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Earlier application is permitted under specific circumstances. The Company is currently assessing the potential impact of this standard on its financial statements.

In AugustMarch 2016 the FASB issued ASU No. 2016-15, Statement of Cash Flows2016-09, Compensation-Stock Compensation (Topic 230)718): Improvements to Employee Share-Based Payment Accounting. This amendment will provide guidance onupdate simplifies the presentationaccounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of specific cash flow items to improve consistency withinin the statement of cash flows.

On April 1, 2017, the Company adopted ASU 2016-15No. 2016-09. As a result of adopting ASU No. 2016-09, the Company has made an accounting policy election to account for forfeitures as they occur. This change has been applied on a modified retrospective basis, with no material impacts on the Company’s financial statements. The adoption of ASU No. 2016-09 also requires excess tax benefits and tax deficiencies be recorded in the income statement as opposed to additional paid-in capital when the awards vest or are settled and recognize all previously unrecognized excess tax benefits and tax deficiencies upon adoption as a cumulative-effect adjustment to retained earnings. As of April 1, 2017, the Company recognized excess tax benefit of approximately $533,000 as an increase to deferred tax assets. However, the entire amount was offset by a full valuation allowance.  Accordingly, no cumulative-effect adjustment to retained earnings was recorded as of September 30, 2017.

Additionally, the adoption of ASU No. 2016-09 related to the accounting for minimum statutory withholding tax requirements and cash paid by an employer when directly withholding shares for tax-withholding purposes had no impact on the Company's current consolidated financial statements or on any prior period financial statements presented.

Recent Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09,Revenue from Contracts with Customers, which supersedes the revenue recognition requirements in Topic 605,Revenue Recognition and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, which defers by one year the effective date of ASU 2014-09. Accordingly, this guidance is effective for fiscal years,interim and interimannual periods within those fiscal years beginning after December 15, 2017 with early adoption permitted.

Description of Sale to Invekra

On October 27, 2016, the Company, along with its Mexican subsidiary and manufacturer Oculus Technologies of Mexico, S.A. de C.V. (“OTM”), closed on an asset purchase agreement with Invekra, S.A.P.I de C.V. (“Invekra”), an affiliate of Laboratorios Sanfer S.A. de C.V., for the sale of certain of its Latin America assets. Specifically, the Company agreed to sell certain patents, patent applications, trademarks and territory rights for Mexico, the Caribbean and South America, excluding the sale of dermatology products in Brazil, as well as to build and deliver equipment that Invekra will use to produce its own product.

The aggregate purchase price that Invekra will pay for the assets is $22,000,000, of which $18,000,000 was paid upon closing, $1,500,000 will be held in escrow until completionwas paid on March 16, 2017 upon the delivery of the Company’s obligations to deliver certain equipment, and $2,500,000 willis to be paid in Mexican currency in quarterly installments over a period of ten years from closing as consideration for the provision of certain services and providing technical assistance, calculated as three per centpercent on net sales of certain products in Latin America, excluding Mexico. Because the $2,500,000 is to be paid in foreign currency, the Company may receive more or less than $2,500,000 due to currency fluctuations. During the six months ended September 30, 2017, the Company recorded $39,000 of service revenue and $33,000 of interest income related to technical assistance which is reflected in the accompanying condensed consolidated statement of comprehensive loss for the six months ended September 30, 2017. The Company agreed to forego recognition any royalty in the second quarter until certain replacement parts will be delivered in the third quarter.

In connection with the asset purchase agreement, the Company agreed to provide the technology, know-how and assistance to Invekra to enable Invekra to manufacture on its own the products as currently produced by the Company (“Technical Services Arrangement”), and continue to supply product to Invekra for a two year transition period from the Sale Date, subject to mutual extension (“Supply Agreement”). During the three and ninesix months ended December 31, 2016,September 30, 2017, the Company reported $465,000$754,000 and $1,323,000, respectively, of Latin America product revenue related to the Supply Agreement with Invekra.

The Company will provide product under the Supply Agreement at a reduced price from its current price list, while Invekra builds its own manufacturing line. At the conclusion of the transition period, the Company will cease to be a supplier of product to Invekra. The Company is uncertain as to the duration of the transition period or when Invekra will complete the build out of its manufacturing line. Pursuant to the Supply Agreement, the Company is subject to a potential penalty for failure to supply the products for a consecutive period of six months. The penalty, if triggered, will require the Company to make a one-time payment of $2,000,000 to Invekra. The penalty decreases by 12.5% each quarter of the term of the supply period. The Company does not expect to incur this penalty. The Company will incur costs of approximately $325,000 to fulfill its obligations to build and deliver certain production equipment to Invekra.

Accounting for the disposition

For accounting purposes, the Company determined that there were three discrete components of the sale to Invekra. These components were the intellectual property and territory rights, the services to be provided under the Technical Services Arrangement and the production equipment to be manufactured for Invekra.

The Company determined an arm’s length selling price for each component of the sale and then allocated the net proceeds received to the components on a relative selling price basis. The Company estimated the selling prices of each component as described below:

The Company determined proceeds, net of estimated transaction costs and net of the discount to adjust for consideration to be received in the future. The total proceeds were as follows:

Proceeds were allocated to the components of the sale based upon their relative selling prices are as follows:

The proceeds related to the intellectual property and territory rights were included in gain on sale on the date of the sale. The proceeds allocated to the services under the Technical Services Agreement were recorded in deferred revenue as of the date of the sale and will be recognized as technical services are provided. The proceeds related to the production equipment to be manufactured were included in deferred gain and will be recognized upon delivery of the equipment.

Discontinued operations

As of December 31, 2016, theThe Company determined that the sale of its Latin American operations to Invekra qualified as a sale of a component of its business and, as such, all such activity prior to consummation of the sale is required to be included in discontinued operations on the Company’s statement of operations. This includes the direct labor and materials for the product delivered to Invekra, the revenue on the sales to Invekra and the gain on the sale to Invekra, net of tax.

The carrying value of the assets and liabilities of discontinued operations on the condensed consolidated balance sheets as of December 31, 2016 and March 31, 2016 were as follows:

Performance Based Awards Program

On April 1, 2017, the Company adopted ASU 2016-09 and, as a result, made a company-wide accounting policy change with respect to accounting for forfeitures. The Company’s Compensation Committee approvedCompany applied a short-term performance based bonus programmodified retrospective approach for fiscal 2016 with predetermined objectives related to revenue and expense targets. In the event the fiscal 2016 objectives were met, eighty-percentadoption of the options would have vested on June 30, 2016. On August 21, 2015, certain executivesnew policy and senior managers were grantedaccordingly recorded an aggregate of 75,500 stock options in connection$11,000 increase to opening accumulated deficit at April 1, 2017. In accordance with this program. The stock options have an exercise price of $5.80 and expire ten years from the date of grant. At March 31, 2016, it was determined targets were met related to 50,400 stock options which vested on June 30, 2016. At March 31, 2016, 10,000 stock options expired due to targets that were not met. The vestingadoption of the remaining 15,100 stock options was at the discretion of the Company’s Compensation Committee to be determined during the three months ended June 30, 2016. The Company’s Compensation Committee determined 14,772 of the 15,100 discretionary stock options vested at June 30, 2016 and 228 of the discretionary stock options expired unvested.

The Company also approved a long-term market-based stock option bonus program for senior managers. Vesting of the stock options granted as part of this program is contingent upon the achievement of four separate target stock prices. The market-based options vest based on the 30 trading day trailing average of the stock price of the Company’s common stock with options vesting in 25% increments at each of the target stock prices. On the last day of each quarter, the chief executive officer and/or chief financial officer will determine if any of the target stock prices have been met by evaluating the period between the quarter end date and the grant date of the option. In the event that a target stock price has been met, the senior manager will be notified that such options have vested. At the end of five years from the date of the grant, if the stock target prices have not been met, then the unvested portion of the option will expire. On August 21, 2015, certain senior managers were granted an aggregate of 23,750 stock options in connection with this program. The stock options have an exercise price of $5.80 and if they vest will expire ten years from the date of grant. None of these options vested as of December 31, 2016.

Stock-Based Compensation

The Company issues service, performance and market-based stock options to employees and non-employees. The Company estimates the fair value of service and performance stock option awards using the Black-Scholes option pricing model. The Company estimates the fair value of market-based stock option awards using a Monte-Carlo simulation. Compensation expense for stock option awards is amortized on a straight-line basis over the awards’ vesting period. Compensation expense includes the impact of an estimate for forfeitures for all stock options.

The expected term of the stock options represents the average period the stock options are expected to remain outstanding and is based on the expected term calculated using the approach prescribed by the Securities and Exchange Commission's Staff Accounting Bulletin No. 110 for “plain vanilla” options. The expected stock price volatility for the Company’s stock options was determined by using an average of the historical volatilities ofaccounting policy, the Company and its industry peers. The Company will continue to analyze the stock price volatility and expected term assumptions as more data for the Company’s common stock and exercise patterns become available. The risk-free interest rate assumption is based on the U.S. Treasury instruments whose term was consistent with the expected term of the Company’s stock options. The expected dividend assumption is based on the Company’s history and expectation of dividend payouts. The Companyno longer estimates forfeitures based on historical experience and no longer reduces compensation expense accordingly. The estimated forfeiture rates used duringbased on the nine months ended December 31, 2016 ranged from 5.24% to 6.01%. The estimated forfeiture rates used duringexpected forfeitures. Beginning April 1, 2017, the nine months ended December 31, 2015 ranged from 1.18% to 1.81%.Company will record forfeitures as they occur and will reduce compensation cost at the time of forfeiture.

The Company estimatedweighted average grant date fair values of options granted during the fair value of employeethree and non-employee stock options using the Black-Scholes option pricing model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service periods of the respective awards. The fair value of employee stock optionssix months ended September 30, 2017 was estimated using the following weighted-average assumptions:$5.58 and $6.01, respectively.

Share-based awards compensation expense is as follows:

At December 31, 2016,September 30, 2017, there were unrecognized compensation costs of $695,000$2,999,000 related to stock-based awardsstock options which areis expected to be recognized over a weighted-average amortization period of 1.362.43 years.

Restricted stock award activity is as follows:

Restricted stock awards were issued to non-employee directors and certain executive officers in the nine months ended December 31, 2016.

No income tax benefit has been recognized relating to stock-based compensation expense and no tax benefits have been realized from exercised stock options.

The Company did not capitalize any cost associated with stock-based compensation.

The Company issues new shares of common stock upon exercise of stock basedoptions or release of restricted stock awards.

The Company’s effective tax rate was 123.28% and 41.31% for the three and nine months ended December 31, 2016, respectively. For the three and nine months ended December 31, 2015, the effective tax rates were 0%. The change in the effective tax rates from continuing operations for the three and nine months ended December 31, 2016 compared to the same period last year is primarily due to the intra-period allocation of total tax expense between continuing operations and discontinued operations from the sale to Invekra.

The Company accounts for the tax effects of discontinued operations as a discrete item and therefore recognizes the full tax effects of discontinued operations in the same period that the pretax income or loss from discontinued operations is recognized. In accordance with the intra-period allocation rules, as a result of having a full valuation allowance on deferred income taxes on the Company’s entire operations, a tax benefit is recorded in continuing operations for the benefit of the utilization of the deferred tax assets resulting from the income from discontinued operations.

During the three and nine months ended December 31, 2016, the Company recorded income tax expense of $4,581,000 within discontinued operations.   This income tax expense was recognized in connection with the gain on sale of the IP and territory rights and the operations through the sale date, associated with the Latin American operations. The Company was able to utilize certain net operating loss carryovers (“NOLs”) of approximately $4,040,000 in order to reduce the amount of its income tax obligations. The Company had previously established a full valuation allowance against the deferred income tax assets, which included these NOLs. During the three and nine months ended December 31, 2016, the Company recorded an income tax benefit of $4,040,000 within its continuing operations, representing the release of the valuation allowance for the NOLs utilized to offset the gain and income reflected in discontinued operations. The NOLs in certain jurisdictions did not fully offset the income tax obligations incurred. As a result, as of December 31, 2016, the Company recorded current income tax payable of $229,000 and deferred income tax liability of $312,000.

The Company has completed a study to assess whether or not a change in control for income tax purposes has occurred.occurred or whether there have been multiple changes of control since the Company’s formation. The Company has determined, based on the results of the study, that no such change in control has occurred for purposes of Internal Revenue Code section 382 and as a result, the Company’s income382. The Company, after considering all available evidence, fully reserved its deferred tax net operating loss carryforwards wereassets since it is more likely than not, limited under such provision.benefits, will not be realized in future periods. The Company incurred losses for both financial reporting and income tax purposes for the year ended March 31, 2016 and through September 30, 2016. The Company, after weighing both positive and negative evidence, had fully reserved its deferred tax assets since it was more likely than not that such benefits would not be realized in future periods. Except as disclosed below in connection with the utilization of net operating loss carryforwards in connection with the gain on the sale to Invekra, as of December 31, 2016,2017. Accordingly, the Company hasis continuing to fully reservedreserve for its deferred tax assets. The Company will continue to evaluate its deferred tax assets in future periods in order to determine whether any changes in circumstances could affect the realization of their future benefit. If it is determined in future periods that portions of the Company’s deferred income tax assets satisfy the realization standards, the valuation allowance will be reduced accordingly.

As a result of certain realization requirements of Accounting Standards Codification Topic 718, the Company’s deferred tax assets and liabilities do not include certain deferred tax assets at December 31, 2016September 30, 2017 that arose directly from tax deductions related to equity compensation in excess of compensation recognized for financial reporting purposes. Equity will be increased by approximately $533,000 if and when such deferred tax assets are ultimately realized.

Additionally, the Company provides technical services to Invekra.

Our Business

We are a specialty pharmaceutical company dedicated to identifying, developing and commercializing unique, affordable differentiated therapies to improve the livesmillions of patients living with dermatologic diseases orchronic skin conditions. OurWe believe our products, which are sold throughout the United States and internationally, have improved patient outcomes for more than five million patients globally by treating and reducing certain topical skin diseases including acne, atopic dermatitis, scarring, infections, itch, pain and harmful inflammatory responses. On December 6, 2016, we changed our name from Oculus Innovative Sciences, Inc. to Sonoma Pharmaceuticals, Inc.

We currently focusare focused on the development and commercialization of therapeutic solutions in medical dermatology to treat or reduce skin conditions, such as acne, atopic dermatitis and scarring. These diseases impact millions of patients worldwide and can have significant, multi-dimensional effects on patients’ quality of life, including their physical, functional and emotional well-being.

Since our founding in 1999, we built our business by developing and promoting products via partnerships for multiple therapeutic indications, with a primary focus on advanced tissue care. Starting in 2013, with a new Board of Directors and new management team, we pivoted to focus on one specialty pharmaceutical area, medical dermatology, and created our own sales force in the United States to promote our unique, affordable, differentiated prescription dermatology products.

Some of our key products in the United States are:

Our key product outside the United States is:

To date,As of September 30, 2017, we have obtained 1517 clearances from the U.S. Food and Drug Administration, or FDA, that permit us to sell our products as medical devices for Section 510(k) of the Federal Food, Drug and Cosmetic Act in the United States.

Outside the United Sates,States, we sell products for dermatological and advanced tissue care with a European Conformity marking (known as Conformité Européenne or CE) covering 25 of our products, and various approvals in China, Southeast Asia, South Korea, India, Australia, New Zealand, and the Middle East.

On October 27, 2016, we, along with our Mexican subsidiary and manufacturer Oculus Technologies of Mexico, S.A. de C.V., closed on an asset purchase agreement with Invekra, S.A.P.I de C.V., an affiliate of Laboratorios Sanfer S.A. de C.V., for the sale of certain of our Latin America assets. Specifically, we agreed to sell certain patents, patent applications, trademarks and territory rights for Mexico, the Caribbean and South America, excluding the sale of dermatology products in Brazil, as well as to build and deliver equipment that Invekra will use to produce its own product.

The aggregate purchase price that Invekra will pay for the assets is $22,000,000, of which $18,000,000 was paid upon closing, $1,500,000 will be held in escrow until completion of our obligation to deliver certain equipment, and $2,500,000 will be paid in Mexican currency in quarterly installments over a period of ten years from closing as consideration for the provision of certain services and providing technical assistance, calculated as three per cent on net sales of certain products in Latin America, excluding Mexico. Since the $2,500,000 is to be paid in foreign currency, we may receive more or less than $2,500,000 due to currency fluctuations.

As a result of the asset purchase agreement and arrangement, we expect our revenues in Latin America will decrease significantly. Pursuant to the arrangement, going forward we will receive a royalty of 3% on all Latin American net revenues (outside of Mexico), with a minimum payment of $250,000 per year for the next ten years, to be paid quarterly in Mexican pesos. Due to currency fluctuations, we may not receive the full $250,000 in U.S. dollars. Additionally, while Invekra sets up their manufacturing, we will continue to supply Invekra with product at a reduced price.

We believe that the sale of the Latin America assets is in line with our overall turnaround strategy to focus on our core dermatology business and generate cash from our non-core businesses to support the higher margin and higher-growth dermatology business. As a result of the sale of our Latin America assets, we expect our Latin America revenues will decrease and our total revenues will decrease in the short-term until our U.S. based dermatology revenues increase longer-term. We believe focusing on higher margin dermatology products, utilizing an internal sales force, allows us to better control and grow our future results rather than relying on external partners for marketing and sales. We intend to use the proceeds from the sale of the Latin America assets to increase our direct sales force and grow our product line and continue to expand our markets and Company.

Our Strategy

Our strategy is to in-license, acquire, develop and commercialize unique, affordable and differentiated therapies that we believe advance the standard of care for patients with dermatological diseases. The key components of our strategy are to:

Our plan is to evolve into a leading dermatology company, providing innovative and cost-effective solutions to patients, while generating strong, consistent revenue growth and maximizing long-term shareholder value.

In addition, sales to a new animal health care partner increased during the period compared to the prior year. Going forward, while we expect sales of both our U.S. dermatology and animal health product lines will continue to grow, we expect sales of our dermatology product lines to grow faster and thus, the percentage of animal sales as a part of our overall sales decrease. Management has determined that our core focus will continue to be prescription dermatology sales.
