Description Of Business Disclosure [Abstract]

DESCRIPTION OF BUSINESS

NOTE 1 - DESCRIPTION OF BUSINESS

Acura Pharmaceuticals, Inc., a New York corporation, and its subsidiary (the “Company”, “We”, “Us” or “Our”) is a specialty pharmaceutical company engaged in the research, development and commercialization of technologies and products intended to address medication abuse and misuse. We have discovered and developed three proprietary platform technologies which can be used to develop multiple products. Our Aversion® and Limitx™ Technologies are intended to address methods of abuse associated with opioid analgesics while our Impede® Technology is directed at minimizing the extraction and conversion of pseudoephedrine into methamphetamine.

⋅

Oxaydo® Tablets (oxycodone HCl, CII), which utilizes the Aversion Technology, is the first and only approved immediate-release oxycodone product in the United States with abuse deterrent labeling. On January 7, 2015, we entered into a Collaboration and License Agreement with Egalet US, Inc. and Egalet Ltd., each a subsidiary of Egalet Corporation (collectively, “Egalet”) pursuant to which we exclusively licensed to Egalet worldwide rights to manufacture and commercialize Oxaydo®. Oxaydo is currently approved by the FDA for marketing in the United States in 5mg and 7.5mg strengths. Egalet launched Oxaydo in the United States late in the third quarter of 2015.

⋅

Nexafed® Tablets (30mg pseudoephedrine) and Nexafed® Sinus Pressure + Pain Tablets (30/325mg pseudoephedrine and acetaminophen), utilizing the Impede Technology, were launched by us into the United States market in December 2012 and February 2015, respectively. We have multiple pseudoephedrine products in development utilizing our Impede Technology. On June 15, 2015, we and Bayer Healthcare LLC entered into a License and Development Agreement pursuant to which we granted Bayer an exclusive worldwide license to our Impede Technology for use in an undisclosed methamphetamine resistant pseudoephedrine – containing product and providing for the joint development of such product using our Impede Technology for the U.S. market.

⋅

Our third abuse deterrent technology, Limitx, is designed to retard the release of active drug ingredients when too many tablets are accidently or purposefully ingested. We have completed our first clinical study, Study AP-LTX-400, of our lead Limitx immediate release oral abuse deterrent drug candidate using the opioid hydromorphone HCI (LTX-04). Study AP-LTX-400, or Study 400, was a two cohort, open label, crossover design pharmacokinetic study in healthy adult subjects. The FDA has designated the development program for LTX-04 as Fast Track, which is designed to facilitate the development, and expedite the review of drugs to treat serious conditions and fill an unmet medical need. On April 13, 2016 and June 8, 2016, we announced that topline interim results from cohorts 1 and 2, respectively, of Study 400 for one test formulation of LTX-04 successfully demonstrated the release of the active opioid ingredient was reduced when three or more tablets were ingested, but that additional formulation development will be required for LTX-04 to deliver a sufficient amount of the active ingredient when one or two tablets are administered. We are also developing an immediate-release hydrocodone bitartrate with acetaminophen product utilizing our Limitx Technology.

Amounts presented have been rounded to the nearest thousand, where indicated, except share and per share data. The equity amounts and all share and per share data of the Company have been retroactively adjusted to reflect a one-for-five reverse stock split effected by us on August 28, 2015.

LIQUIDITY MATTERS [Abstract]

LIQUIDITY MATTERS

NOTE 2 – LIQUIDITY MATTERS

The accompanying financial statements have been prepared assuming the Company will continue as a going concern. At June 30, 2016, we had unrestricted cash, cash equivalents and marketable securities (after deduction of a $2.5 million compensating balance requirement under our term loan with Oxford) of $4.3 million, unrestricted working capital of $1.2 million, and an accumulated deficit of $374.0 million. We had a loss from operations of $6.2 million and a net loss of $6.7 million for the six months ended June 30, 2016.

We estimate that our current unrestricted cash, cash equivalent and marketable securities will be sufficient to fund the development of our products utilizing our Limitx and Impede Technologies, the commercialization of our Nexafed products and our related operating expenses through November 2016 while maintaining compliance with the $2.5 million compensating balance requirement under our term loan with Oxford Finance LLC. At August 5, 2016, we had unrestricted cash, cash equivalents and marketable securities (after deduction of the $2.5 million compensating balance requirement under our term loan with Oxford) of $3.4 million. To fund further operations and product development activities, we must raise additional financing or enter into license or collaboration agreements with third parties relating to our technologies. No assurance can be given that we will be successful in obtaining any such financing or in securing license or collaboration agreements with third parties on acceptable terms, if at all, or if secured, that such financing or license or collaboration agreements will provide payments to the Company sufficient to fund continued operations. In the absence of such financing or third-party license or collaboration agreements, the Company will be required to scale back or terminate operations and/or seek protection under applicable bankruptcy laws. An extended delay or cessation of the Company’s continuing product development efforts will have a material adverse effect on the Company’s financial condition and results of operations.

In view of the matters described above, recoverability of a major portion of the recorded asset amounts shown in the Company’s accompanying balance sheets is dependent upon continued operations of the Company, which in turn is dependent upon the Company’s ability to meet its financing requirements on a continuous basis, to maintain existing financing and to succeed in its future operations. The Company’s financial statements do not include any adjustment relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.

ACCOUNTING PRONOUNCEMENTS

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

ACCOUNTING PRONOUNCEMENTS

NOTE 3 – ACCOUNTING PRONOUNCEMENTS

Revenue from Contracts with Customers

In May 2014 the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-09). ASU 2014-09 provides a comprehensive new recognition model that requires recognition of revenue when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to receive in exchange for those goods or services. This guidance supersedes the revenue recognition requirements in FASB ASC Topic 605, “Revenue Recognition,” and most industry-specific guidance. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, companies will need to use more judgment and make more estimates than under the current guidance. It also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. In August 2015, the FASB approved a one-year deferral of the effective date (ASU 2015-14) and the standard is now effective for the Company for fiscal 2019 and interim periods therein. ASU 2014-09 may be adopted as of the original effective date, which for the Company is fiscal 2018. The guidance may be applied using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures).

In addition, in March 2016, the FASB issued ASU Update 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients and ASU 2016-11, Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting. These amendments provide additional clarification and implementation guidance on the previously issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606).

The amendments in ASU 2016-08 clarify how an entity should identify the specified good or service for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements. ASU 2016-10 clarifies the following two aspects of ASU 2014-09: identifying performance obligations and licensing implementation guidance. ASU 2016-11 rescinds several SEC Staff Announcements that are codified in Topic 605, including, among other items, guidance relating to accounting for consideration given by a vendor to a customer, as well as accounting for shipping and handling fees and freight services. ASU 2016-12 provides clarification to Topic 606 on how to assess collectability, present sales tax, treat noncash consideration, and account for completed and modified contracts at the time of transition. In addition, ASU 2016-12 clarifies that an entity retrospectively applying the guidance in Topic 606 is not required to disclose the effect of the accounting change in the period of adoption. The effective date and transition requirements for these amendments are the same as the effective date and transition requirements of ASU 2014-09, which is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2018. The Company is currently assessing the impact of these ASUs on its results of operations, cash flows or financial condition.

Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern

In August 2014, the FASB issued ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”, which will explicitly require management to assess an entity’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. Currently, there is no guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern or to provide related footnote disclosures. The amendments in this Update provide that guidance. In doing so, the amendments should reduce diversity in the timing and content of footnote disclosures. The amendments require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). The amendments in this update are effective for the first annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is currently evaluating the impact of adopting this update on its financial statements.

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.

LICENSE, DEVELOPMENT, AND COMMERCIALIZATION AGREEMENTS

Research and Development Disclosure [Abstract]

LICENSE, DEVELOPMENT, AND COMMERCIALIZATION AGREEMENT

NOTE 4 - LICENSE, DEVELOPMENT, AND COMMERCIALIZATION AGREEMENTS

Egalet Agreement

On January 7, 2015, we and Egalet entered into a Collaboration and License Agreement (the “Egalet Agreement”) to commercialize Aversion Oxycodone (formerly known as Oxecta®) under our tradename Oxaydo. Oxaydo is approved by the FDA for marketing in the United States in 5 mg and 7.5 mg strengths. Under the terms of the Egalet Agreement, we transferred the approved New Drug Application, or NDA, for Oxaydo to Egalet and Egalet is granted an exclusive license under our intellectual property rights for development and commercialization of Oxaydo worldwide (the “Territory”) in all strengths, subject to our right to co-promote Oxaydo in the United States. Eaglet launched Oxaydo in the United States late in the third quarter of 2015.

In accordance with the Egalet Agreement, we and Egalet have formed a joint steering committee to coordinate commercialization strategies and the development of product line extensions. Egalet will pay a significant portion of the expenses and we will pay for the remaining costs relating to (i) annual NDA PDUFA product fees, (ii) expenses of the FDA required post-marketing study for Oxaydo and (iii) expenses of clinical studies for product line extensions (additional strengths) of Oxaydo for the United States and Egalet will bear all of the expenses of development and regulatory approval of Oxaydo for sale outside the United States. Egalet is responsible for all manufacturing and commercialization activities in the Territory for Oxaydo. Subject to certain exceptions, Egalet will have final decision making authority with respect to all development and commercialization activities for Oxaydo, including pricing, subject to our co-promotion right. Egalet may develop Oxaydo for other countries and in additional strengths, in its discretion.

Egalet paid us a $5.0 million license fee upon signing of the Egalet Agreement and on October 9, 2015, paid us a $2.5 million milestone in connection with the first commercial sale of Oxaydo. We will be entitled to a one-time $12.5 million milestone payment when worldwide Oxaydo net sales reach $150 million in a calendar year. We are receiving from Egalet a stepped royalty at percentage rates ranging from mid-single digits to double-digits based on Oxaydo net sales during each calendar year (excluding net sales resulting from our co-promotion efforts). In any calendar year of the agreement in which net sales exceed a specified threshold, we will receive a double digit royalty on all Oxaydo net sales in that year (excluding net sales resulting from our co-promotion efforts). If we exercise our co-promotion rights, we will receive a share of the gross margin attributable to incremental Oxaydo net sales from our co-promotion activities. Egalet’s royalty payment obligations commence on the first commercial sale of Oxaydo and expire, on a country-by-country basis, upon the expiration of the last to expire valid patent claim covering Oxaydo in such country (or if there are no patent claims in such country, then upon the expiration of the last valid claim in the United States or the date when no valid and enforceable listable patent in the FDA’s Orange Book remains with respect to Oxaydo). Royalties will be reduced upon the entry of generic equivalents, as well as for payments required to be made by Egalet to acquire intellectual property rights to commercialize Oxaydo, with an aggregate minimum floor.

The Egalet Agreement expires upon the expiration of Egalet’s royalty payment obligations in all countries. Either party may terminate the Egalet Agreement in its entirety if the other party breaches a payment obligation, or otherwise materially breaches the Egalet Agreement, subject to applicable cure periods, or in the event the other party makes an assignment for the benefit of creditors, files a petition in bankruptcy or otherwise seeks relief under applicable bankruptcy laws. We also may terminate the Egalet Agreement with respect to the U.S. and other countries if Egalet materially breaches its commercialization obligations. Egalet may terminate the Egalet Agreement for convenience on 120 days prior written notice, which termination may not occur prior to the second anniversary of Egalet’s launch of Oxaydo. Termination does not affect a party’s rights accrued prior thereto, but there are no stated payments in connection with termination other than payments of obligations previously accrued. For all terminations (but not expiration), the Egalet Agreement provides for the transition of development and marketing of Oxaydo from Egalet to us, including the conveyance by Egalet to us of the trademarks and all regulatory filings and approvals relating to Oxaydo, and for Egalet’s supply of Oxaydo for a transition period.

Bayer Agreement

On June 15, 2015, we and Bayer entered into a License and Development Agreement (the “Bayer Agreement”) granting Bayer an exclusive worldwide license to our Impede Technology for use in an undisclosed methamphetamine resistant pseudoephedrine–containing product (the “Bayer Licensed Product”) and providing for the joint development of such product utilizing our Impede Technology for the U.S. market. The Bayer Agreement also grants Bayer first right to negotiate a license to the Impede Technology for certain other products.

We and Bayer have formed a joint development committee to coordinate development of the Bayer Licensed Product. We will be eligible to receive reimbursement of certain of our development costs, success-based development and regulatory milestones payments, and low mid-single digit royalties on net sales of the Bayer Licensed Product in countries with patent coverage and a reduced royalty elsewhere.

The term of the Bayer Agreement with respect to each country expires when royalties are no longer payable with respect to such country. After expiration of the term Bayer retains a license to sell the Bayer Licensed Product on a royalty free basis. Either party may terminate the Bayer Agreement in its entirety if the other party materially breaches the Bayer Agreement, subject to an applicable cure period, or in the event the other party makes an assignment for the benefit of creditors, files a petition in bankruptcy or otherwise seeks relief under applicable bankruptcy laws. Bayer may terminate the Bayer Agreement immediately prior to completion of our development obligations or at any time upon six (6) months prior written notice thereafter. We may terminate the Bayer Agreement with respect to the U.S. if Bayer ceases or suspends development or commercialization of the Bayer Licensed Product for a certain period of time.

Purdue Pharma

The Company received a $250 thousand payment from Purdue Pharma L.P. in June 2015 relating to a December 2014 agreement to settle a patent interference action on U.S. Patent No. 8,101,630 issued to Acura.

Terminated Pfizer Agreement

In 2007, we entered into License, Development and Commercialization Agreement for Oxaydo (named Oxecta® under a Pfizer trademark) and other Aversion opioid development products with King Pharmaceuticals Research and Development, Inc., which became a subsidiary of Pfizer in 2011 (the “Pfizer Agreement”). In April 2014, we entered into a letter agreement with Pfizer providing for the termination of the Pfizer Agreement and the return to us of Oxaydo and all Aversion product rights in exchange for a one-time termination payment of $2.0 million. Our termination payment of $2.0 million has been recorded in our consolidated financial statements as an intangible asset and is being amortized over the remaining useful life of the patent covering Oxaydo. During each of the six month periods ending June 30, 2016 and 2015, we recognized amortization expense on this intangible asset of $103 thousand. At June 30, 2016 the unamortized portion of the intangible asset was $1.5 million. We also purchased from Pfizer in April 2014 selected raw and packaging material inventories relating to Oxaydo for $260 thousand. During the six months ended 2015, we recorded a $260 thousand inventory obsolescence expense on these inventories.

Revenue Recognition [Abstract]

REVENUE RECOGNITION

NOTE 5 - REVENUE RECOGNITION

License Fee Revenue

On January 7, 2015, we and Egalet entered into a Collaboration and License Agreement to commercialize Oxaydo tablets (formerly known as Oxecta) utilizing our Aversion® Technology. Egalet paid us $5.0 million upon signing the Egalet Agreement. The payment was non-refundable and non-creditable when made and we had no further requirements to earn the payment. The amount was recognized as revenue when received (see Note 4).

Collaboration Revenue

Collaboration revenue is derived from reimbursement of development expenses, such as under the Bayer Agreement, and are recognized when costs are incurred pursuant to the agreement. The ongoing research and development services being provided under the collaboration are priced at fair value based upon the reimbursement of labor and expenses incurred pursuant to the collaboration agreements. During the three and six month periods ended June 30, 2016, we recognized collaboration revenue of $133 thousand and $233 thousand, respectively. We did not recognize any collaboration revenue during the same periods in 2015.

Royalty Revenue

In connection with our Collaboration and License Agreement with Egalet to commercialize Oxaydo tablets we will receive a stepped royalty at percentage rates ranging from mid-single digits to double-digits based on Oxaydo net sales during each calendar year over the term of the agreement (excluding net sales resulting from any co-promotion efforts by us). We recognize royalty revenue each calendar quarter based on net sales reported to us by Egalet in accordance with the agreement. Egalet’s first commercial sale of Oxaydo occurred in October 2015. We recognized royalty revenue of $30 thousand and $47 thousand on Oxaydo net sales during the three and six month periods, respectively, ended June 30, 2016. We did not recognize any royalty revenue during the same periods in 2015. (see Note 4).

Product Sales

Nexafed was launched in mid-December 2012 and Nexafed Sinus Pressure + Pain was launched in February 2015. We sell our Nexafed products in the United States to wholesale pharmaceutical distributors as well as directly to chain drug stores. Our Nexafed products are sold subject to the right of return usually for a period of up to twelve months after the product expiration. The Nexafed products currently have a shelf life of twenty-four months from the date of manufacture. Given the limited sales history of our Nexafed products, we could not reliably estimate expected returns of the product at the time of shipment to certain customers. During the first quarter of 2015, we determined we had obtained sufficient sales returns history to reasonably estimate future product returns from those customers. We recorded a one-time adjustment in the first quarter of 2015 to recognize revenue that had previously been deferred, resulting in additional net revenues of $314 thousand after recording a liability for sales returns of $120 thousand, and additional cost of sales of $255 thousand. We currently recognize revenue from our Nexafed product line when the price is fixed and determinable at the date of sale, title and risk of ownership have been transferred to the customer. At June 30, 2016 and December 31, 2015, we had a $263 thousand and $205 thousand sales returns liability, respectively, which is reviewed against sales returns activity each calendar quarter for adjustment.

Shipping and Handling Costs

We record shipping and handling costs in selling expenses. The amounts recorded to selling expenses from the shipments of the Nexafed product line during each of the six month periods ended June 30, 2016 and 2015 were not material.

Total marketable securities	$	3.5	$	10.8

The Company’s marketable securities are classified as available-for-sale and are recorded at fair value based on quoted market prices or net asset value using the specific identification method. The purchase cost of corporate bonds may include a purchase price premium or discount which will be amortized or accreted against earned interest income to the maturity date of the bond. Our investments are classified as current in the Company’s Consolidated Balance Sheets as they may be sold within one year in response to changes in market prices or interest rates, to realign our investment concentrations or to meet our working capital needs.

The following tables provide a summary of the fair value and unrealized gains (losses) related to the Company’s available-for-sale securities:

Fair Value Measurement

Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants. Fair values determined based on Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined based on Level 2 inputs utilize observable quoted prices for similar assets and liabilities in active markets and observable quoted prices for identical or similar assets in markets that are not very active. Fair values determined based on Level 3 inputs utilize unobservable inputs and include valuations of assets or liabilities for which there is little, if any, market activity. A financial asset or liability’s classification within the above hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Our assets measured at fair value or disclosed at fair value on a recurring basis as at June 30, 2016 and December 31, 2015 consisted of the following:

	June 30, 2016

Debt Disclosure [Abstract]

DEBT

NOTE 11 – DEBT

On December 27, 2013, we entered into a Loan and Security Agreement (the “Loan Agreement”) with Oxford Finance LLC (“Oxford” or the “Lender”), for a term loan to the Company in the principal amount of $10.0 million (the “Term Loan”). The full principal amount of the Term Loan was funded on December 27, 2013. We are using the proceeds of the Loan Agreement for general working capital and to fund our business requirements. The Term Loan accrues interest at a fixed rate of 8.35% per annum (with a default rate of 13.35% per annum). The Company was required to make monthly interest–only payments until April 1, 2015 (“Amortization Date”) and on the Amortization Date, the Company began to make payments of principal and accrued interest in equal monthly installments of $260 thousand sufficient to amortize the Term Loan through the maturity date of December 1, 2018. All unpaid principal and accrued and unpaid interest with respect to the Term Loan is due and payable in full on December 1, 2018. As of June 30, 2016, we have made $3.0 million in principal payments on the Term Loan and the balance of term Loan is $7.0 million. As security for its obligations under the Loan Agreement, the Company granted Lender a security interest in substantially all of its existing and after–acquired assets, exclusive of its intellectual property assets. Pursuant to the Loan Agreement, the Company is not allowed to pledge its intellectual property assets to others. Upon the execution of the Loan Agreement, we issued to the Lender warrants to purchase an aggregate of up to 60 thousand shares of our common stock at an exercise price equal to $7.98 per share (after adjustment for our one-for-five reverse stock split) (the “Warrants”). We recorded $400 thousand as debt discount associated with the fair value of the Warrants and are amortizing it to interest expense over the term of the loan using the loan’s effective interest rate. The Warrants are immediately exercisable for cash or by net exercise and will expire December 27, 2020. The fair value of the warrants was determined using the Black-Scholes option-pricing model. Significant assumptions used in the Black-Scholes model were:

Expected dividend yield	0.0	%
Risk-free interest rate	2.4	%
Expected volatility	92	%
Expected term (years)	7

On January 7, 2015, we and Oxford entered into an amendment to the Loan Agreement. Pursuant to the amendment, (i) the exercise price of the Warrants was lowered from $7.98 to $2.52 per share (the average closing price of our common stock on Nasdaq for the 10 trading days preceding the date of the amendment and after giving effect to our one-for-five reverse stock split) and we recorded additional debt discount of $33 thousand representing the fair value of the warrant modification, (ii) we agreed to a compensating balance requirement under which we are required to maintain $2.5 million cash reserves until such time as we have repaid $5.0 million in principal of the Term Loan, and (iii) the Lender consented to the terms of our Collaboration and License Agreement with Egalet relating to our Oxaydo product.

The Company may voluntarily prepay the Term Loan in full, but not in part, and any prepayment is subject to a prepayment premium equal to 1% of the principal prepaid. In addition, at the maturity, termination or upon voluntary or mandatory prepayment of the Term Loan the Company must pay the Lender an additional one-time interest payment of $795 thousand. We are accruing additional monthly interest expense over the term of the loan for this additional one-time interest payment using the loan’s effective cash interest rate. As of June 30, 2016, we have accrued and accumulated $477 thousand of additional interest.

The Company was obligated to pay customary lender fees and expenses, including a one-time facility fee of $50 thousand and the Lender’s expenses in connection with the Loan Agreement. Combined with the Company’s own expenses and a $100 thousand consulting placement fee, the Company incurred $231 thousand in deferred debt issue costs. We are amortizing these costs, including debt modification additional costs, into interest expense over the term of the loan using the loan’s effective interest rate of 10.16%.

The Loan Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, among others, limits or restrictions on the Company’s ability to incur liens, incur indebtedness, pay dividends, redeem stock, and merge or consolidate and dispose of assets. In addition, it contains customary events of default that entitles the Lender to cause any or all of the Company’s indebtedness under the Loan Agreement to become immediately due and payable. The events of default (some of which are subject to applicable grace or cure periods), include, among other things, non–payment defaults, covenant defaults, a material adverse change in the Company, bankruptcy and insolvency defaults and material judgment defaults.

Our debt is summarized below (in thousands):

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

SHARE-BASED COMPENSATION

NOTE 14 - SHARE-BASED COMPENSATION

Share-based Compensation

We have four share-based compensation plans covering stock options and RSUs for our employees and directors.

We measure our compensation cost related to share-based payment transactions based on fair value of the equity or liability instrument issued. For purposes of estimating the fair value of each stock option unit on the date of grant, we utilize the Black-Scholes option-pricing model. Option valuation models require the input of highly subjective assumptions including the expected volatility factor of the market price of our common stock (as determined by reviewing our historical public market closing prices). Our accounting for share-based compensation for RSUs is based on the market price of our common stock on the date of grant, less its exercise cost.

Our share-based compensation expense recognized in the Company’s results of operations from all types of issued instruments comprised the following (in thousands):

	Three months Ended June 30,				Six months Ended June 30,
	2016		2015		2016		2015
Research and development expense:
Stock options	$	43	$	39	$	85	$	78
Restricted stock units		-		-		-		-
Subtotal	$	43	$	39	$	85	$	78

General and administrative expense:
Stock options	$	77	$	88	$	155	$	186
Restricted stock units		30		24		60		47
Subtotal	$	107	$	112	$	215	$	233

Total	$	150	$	151	$	300	$	311

Stock Option Award Plans

We have two stock option plans in effect, and one stock option plan has expired by its terms, but pursuant to which stock options have been granted and remain outstanding. Our stock option award activity during the six month periods ended June 30, 2016 and 2015 is shown below:

	Six months Ended June 30,
	2016				2015
	Number of Options (000’s)		Weighted Average Exercise Price		Number of Options (000’s)		Weighted Average Exercise Price
Outstanding, beginning		1,198	$	15.67		911	$	20.70
Granted		-		-		-		-
Exercised		-		-		-		-
Forfeited or expired		-		-		(15)		26.25
Outstanding, ending		1,198	$	15.67		896	$	20.65
Options exercisable		938	$	19.43		744	$	24.10

There was no intrinsic value of option awards which were vested and outstanding at June 30, 2016. The intrinsic value of the option awards which were vested and outstanding at December 31, 2015 was $6 thousand. The total remaining unrecognized compensation cost on unvested option awards outstanding at June 30, 2016 was $471 thousand, and is expected to be recognized in operating expense over the 17 months remaining in the requisite service periods.

Restricted Stock Unit Award Plan

We have a Restricted Stock Unit Award Plan (the “2014 RSU Plan”) for our employees and non-employee directors. Vesting of an RSU entitles the holder to receive a share of our common stock on a distribution date. The share-based compensation cost to be incurred on a granted RSU is the RSU’s fair value, which is the market price of our common stock on the date of grant, less its exercise cost. The compensation cost is amortized to expense over the vesting period of the RSU award.

A summary of the grants under the RSU Plans consisted of the following:

	Six months Ended June 30,
	2016				2015
	(in thousands)
	Number of RSUs		Number of Vested RSUs		Number of RSUs		Number of Vested RSUs
Outstanding, beginning		45		45		30		30

Vested		-		44		-		20
Forfeited or expired		-		-		-		-
Outstanding, ending		91		47		45		24

Our 2014 RSU Plan was approved by shareholders on May 1, 2014 and permits the grant of up to 400 thousand shares of our common stock pursuant to awards under the 2014 RSU Plan. As of June 30, 2016, 242 thousand shares are available for award under the 2014 RSU Plan.

Information about the RSU grants under the 2014 RSU Plan is as follows:

⋅

On January 2, 2015, we awarded approximately 10.3 thousand RSUs to each of our 4 non-employee directors which also allow for them to receive payment in cash, instead of stock, for up to 40% of each RSU award. Such awards vest 25% at the end of each calendar quarter in 2015. The RSU awards subject to cash settlement are subject to marked-to market accounting and the liability recorded in the Company’s balance sheet was $45 thousand at December 31, 2015. Distributions of stock under the January 2, 2015 award could not be deferred until a later date and the stock under such awards was distributed on January 4, 2016.

⋅

On January 4, 2016, we awarded approximately 22.0 thousand RSUs to each of our 4 non-employee directors which also allow for them to receive payment in cash, instead of stock, for up to 40% of each RSU award. Such awards vest 25% at the end of each calendar quarter in 2016. The RSU awards subject to cash settlement are subject to marked-to market accounting and the liability recorded in the Company’s balance sheet was $34 thousand at June 30, 2016. Distributions of stock under the January 4, 2016 award are generally distributed on the first business day of the year after vesting, but such distribution can be deferred until a later date at the election of the non-employee director.

Information about the distribution of shares under the 2014 RSU Plan is as follows:

⋅

On January 2, 2015, 25.8 thousand RSUs from the May 1, 2014 award were distributed and 3.6 thousand RSUs were deferred until a future distribution date. Of the 25.8 thousand RSUs distributed, 19.8 thousand RSUs were distributed in common stock and 6 thousand RSUs were settled in cash.

⋅

On January 4, 2016, 41.2 thousand RSUs from the January 2, 2015 award were distributed and 1.2 thousand RSUs from the May 1, 2014 award were distributed. Approximately 2.4 thousand RSUs from the May 1, 2014 award are being deferred until a future distribution date. Of the 42.4 thousand RSUs distributed, 32.8 thousand RSUs were distributed in common stock and 9.6 thousand RSUs were settled for $23.8 thousand.

INCOME TAXES

Income Tax Disclosure [Abstract]

INCOME TAXES

NOTE 15 – INCOME TAXES

We account for income taxes under the liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between financial reporting and income tax basis of assets and liabilities and are accounted for using the enacted income tax rates and laws that will be in effect when the differences are expected to reverse. Additionally, net operating loss and tax credit carryforwards are reported as deferred income tax assets. The realization of deferred income tax assets is dependent upon future earnings. A valuation allowance is required against deferred income tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the deferred income tax assets may not be realized. At both June 30, 2016 and December 31, 2015, all our remaining net deferred income tax assets were offset by a valuation allowance due to uncertainties with respect to future utilization of net operating loss (“NOL”) carryforwards. If in the future it is determined that additional amounts of our deferred income tax assets would likely be realized, the valuation allowance would be reduced in the period in which such determination is made and an additional benefit from income taxes in such period would be recognized. We have approximately $52.8 million federal income tax benefits at December 31, 2015 derived from $155.2 million Federal NOLs at the U.S. statutory tax rate of 34% and $2.0 million state NOLs, available to offset future taxable income, some of which already have limitations for future use as prescribed under IRC Section 382. Our Federal and state NOLs will expire in varying amounts between 2016 and 2035 if not used, and those expirations will cause fluctuations in our valuation allowances. As of December 31, 2015, we had federal research and development tax credits of approximately $1.2 million, which expire in the years 2024 through 2034. We also had approximately $0.2 million of Indiana state research and development tax credits, which expire in the years 2016 and 2017.

EARNINGS PER SHARE ("EPS")

Earnings Per Share [Abstract]

EARNINGS PER SHARE ("EPS")

NOTE 16 – EARNINGS PER SHARE (“EPS”)

Basic EPS is computed by dividing net income or loss by the weighted average common shares outstanding during a period, including shares weighted related to vested Restricted Stock Units (“RSUs”) (see Note 14). Diluted EPS is based on the treasury stock method and computed based on the same number of shares used in the basic share calculation and includes the effect from potential issuance of common stock, such as shares issuable pursuant to the exercise of stock options and stock warrants, assuming the exercise of all in-the-money stock options and warrants. Common stock equivalents are excluded from the computation where their inclusion would be anti-dilutive. No such adjustments were made for 2016 and 2015 as the Company reported a net loss for both the six month and three month periods ending June 30 and including the effects of 1.3 million and 1.0 million common stock equivalents from those periods in the diluted EPS calculations would have been antidilutive.

A reconciliation of the numerators and denominators of basic and diluted EPS consisted of the following:

	Three months Ended June 30,				Six months Ended June 30,
	2016		2015		2016		2015

Purdue Pharma Complaints

In April 2015, Purdue Pharma L.P., Purdue Pharmaceuticals L.P. and The P.F. Laboratories, Inc. (collectively, “Purdue”) commenced a patent infringement lawsuit against us and our Oxaydo product licensee Egalet US, Inc. and its parent Egalet Corporation in the United States District Court for the District of Delaware alleging our Oxaydo product infringes Purdue’s U.S. Patent No. 8,389,007 (the “ 007 patent”). In April 2016, Purdue commenced a second patent infringement lawsuit against us and Egalet in the United States District Court for the District of Delaware alleging our Oxaydo product infringes Purdue’s newly issued U.S. Patent No. 9,308,171 (the “171 Patent”). The actions regarding the 007 Patent and the 171 Patent are collectively referred to as the “Actions”. On April 6, 2016, we filed a petition for Inter Partes Review (the “IPR Review”) with the U.S. Patent and Trademark Office (“USPTO”) seeking to invalidate Purdue’s 007 Patent.

On May 20, 2016, Purdue on behalf of themselves and certain affiliates, Egalet Corporation, on behalf of itself and its affiliates and we, on behalf of ourselves and our affiliates entered into a settlement agreement (the “Settlement Agreement”) to settle the Actions and the IPR Review. Under the Settlement Agreement the parties dismissed or withdrew the Actions, requested that the USPTO terminate the IPR Review and exchanged mutual releases. No payments were made under the Settlement Agreement.

The Settlement Agreement also provides that Purdue will not, in the future, assert certain Purdue U.S. patents, including the 007 Patent, the 171 Patent and related technologies (the “Purdue Patents”) against any Acura Settlement Product or Egalet Settlement Product (except generally in an action or interference by Acura or Egalet challenging a Purdue Patent). Acura Settlement Products and Egalet Settlement Products are certain immediate-release and extended-release products, including Oxaydo. In addition, the Settlement Agreement provides that Purdue will not challenge, with certain exceptions, the Acura/Egalet Patents with respect to the Purdue Settlement Products (as defined below) and that Purdue provides Acura and/or Egalet certain waivers of non-patent marketing exclusivity with respect to Purdue Settlement Products.

The Settlement Agreement also provides that Acura and Egalet will not, in the future, assert certain Acura and/or Egalet U.S. patents (the “Acura/Egalet Patents”), including Acura’s Aversion® Technology patents, against any Purdue Settlement Products (except generally in an action or interference by Purdue challenging an Acura/Egalet Patent). Purdue Settlement Products are certain immediate-release and extended-release products. In addition, the Settlement Agreement provides that Acura and Egalet will not challenge, with certain exceptions, the Purdue Patents with respect to the Acura Settlement Products and Egalet Settlement Products and that Acura and Egalet provide Purdue certain waivers of non-patent marketing exclusivity with respect to the Acura Settlement Products and Egalet Settlement Products. In addition, Purdue has certain rights to negotiate to exclusively distribute an authorized generic version of certain Egalet Settlement Products, including, in some circumstances, Oxaydo® and other products using Acura’s Aversion® Technology if licensed to Egalet.

The Settlement Agreement specifically excludes our patents related to our Impede® and Limitx™ technologies from the scope of the Acura/Egalet Patents under the Settlement Agreement.

In December 2014, the Company entered into an agreement with Purdue Pharma L.P. to settle a patent interference action regarding certain intellectual property held by Acura (U.S. Patent No. 8,101,630). The dispute centered upon the issue of which company has priority in developing the invention. The parties agreed to forgo protracted litigation and the uncertainties arising therefrom by entering an agreement whereby the Company conceded Purdue Pharma’s claim of priority in exchange for certain financial consideration to us including an immediate non-refundable payment of $500 thousand. In June 2015, the Company received an additional $250 thousand payment from Purdue Pharma relating to the December 2014 agreement.

Reglan®/Metoclopramide Litigation

Halsey Drug Company, as predecessor to us, has been named along with numerous other companies as a defendant in cases filed in three separate state coordinated litigations pending in Pennsylvania, New Jersey and California, respectively captioned In re: Reglan®/Metoclopramide Mass Tort Litigation, Philadelphia County Court of Common Pleas, January Term, 2010, No. 01997; In re: Reglan Litigation, Superior Court of New Jersey, Law Division, Atlantic County, Case No. 289, Master Docket No. ATL-L-3865-10; and Reglan/Metoclopramide Cases, Superior Court of California, San Francisco County, Judicial Council Coordination Proceeding No. 4631, Superior Court No.: CJC-10-004631. In addition, Acura was served with a similar complaint by two individual plaintiffs in Nebraska federal court, which plaintiffs voluntarily dismissed in December 2014. In this product liability litigation against numerous pharmaceutical product manufacturers and distributors, including Acura, plaintiffs claim injuries from their use of the Reglan brand of metoclopramide and generic metoclopramide.

In the Pennsylvania action, over 200 lawsuits have been filed against Acura and Halsey Drug Company alleging that plaintiffs developed neurological disorders as a result of their use of the Reglan brand and/or generic metoclopramide. In the New Jersey action, plaintiffs filed approximately 150 lawsuits against us, but served less than 50 individual lawsuits upon us. In the California action, there are 89 pending cases against us, with more than 445 individual plaintiffs.

In the lawsuits filed to date, plaintiffs have not confirmed they ingested any of the generic metoclopramide manufactured by Acura. We discontinued manufacture and distribution of generic metoclopramide more than 19 years ago. In addition, we believe the June 23, 2011 decision by the U.S. Supreme Court in PLIVA v. Mensing (“Mensing decision”) holding that state tort law failure to warn claims against generic drug companies are pre-empted by the 1984 Hatch-Waxman Act Amendments and federal drug regulations will assist us in favorably resolving these cases.

In New Jersey, Generic Defendants, including Acura, filed dispositive motions based on the Mensing decision, which the Court granted with a limited exception. In June 2012, the New Jersey trial court dismissed all of the New Jersey cases pending against Acura with prejudice.

In Pennsylvania, and California, Generic Defendants, including Acura, also filed dispositive motions based on the Mensing decision.

In Pennsylvania, on November 18, 2011, the trial court denied Generic Defendants’ dispositive preemption motions, without prejudice. In July 2013, the Pennsylvania Superior Court issued an adverse decision, and a subsequent appeal to the Pennsylvania Supreme Court was denied. On December 16, 2014, the Generic Defendants filed a Joint Petition for Certiorari with the United States Supreme Court captioned Teva Pharmaceuticals USA, Inc. et al. v. Dorothy Bentley, et al., No. 14-711 (U.S.) seeking reversal of the Pennsylvania state court decision. On April 27, 2015, the U.S. Supreme Court denied this Petition and this matter has been returned to the trial court for further proceedings. From July, 2015 to date, the court has been moving forward with procedural steps to narrow this litigation, including requests for plaintiffs to voluntarily discontinue cases, such as those filed against Acura, where there is no case-specific product identification. Acura is optimistic that all of these Philadelphia cases will eventually be dismissed against it based upon the favorable aspects of the Superior Court’s narrow preemption ruling and lack of product identification, although there can be no assurance in this regard. Legal fees related to this matter are currently covered by Acura’s insurance carrier.

In California, the trial court entered a May 25, 2012 Order denying Generic Defendants’ dispositive preemption motions. The Generic Defendants’ appeals from this order were denied by the California appellate courts. In May 2014, the California Court denied a subsequent demurrer and motion to strike seeking dismissal of plaintiffs’ manufacturing defect and defective product claims to the extent that they are barred by federal preemption based upon the June 2013 Bartlett decision. Thus far, Acura and most Generic Defendants have not been required to file answers or other responsive pleadings in each individual case in which they are named defendants. On May 24, 2016, the Court entered an Order approving a stipulation which stays the individual cases against Acura and provides for an agreed upon dismissal protocol for all cases where is a lack of product identification. To date, none of these plaintiffs have confirmed they ingested any of the generic metoclopramide manufactured by Acura. Therefore, we expect that the lawsuits filed by most, if not all, plaintiffs will be dismissed voluntarily. Action will be taken in an effort to dismiss Acura from these cases, although there can be no assurance in this regard. Legal fees related to this matter are currently covered by our insurance carrier.

As any potential loss is neither probable nor estimable, we have not accrued for any potential loss related to these matters as of June 30, 2016 and we are presently unable to determine if any potential loss would be covered by our insurance carrier.

Egalet Agreement

In accordance with the Egalet Agreement, we and Egalet have formed a joint steering committee to coordinate commercialization strategies and the development of product line extensions. Egalet will pay a significant portion of the expenses and we will pay for the other remaining portion of costs relating to (i) annual NDA PDUFA product fees, (ii) expenses of the FDA required post-marketing study for Oxaydo and (iii) expenses of clinical studies for product line extensions (additional strengths) of Oxaydo for the United States and Egalet will bear all of the expenses of development and regulatory approval of Oxaydo for sale outside the United States. Egalet is responsible for all manufacturing and commercialization activities in the Territory for Oxaydo. Subject to certain exceptions, Egalet will have final decision making authority with respect to all development and commercialization activities for Oxaydo, including pricing, subject to our co-promotion right. Egalet may develop Oxaydo for other countries and in additional strengths, in its discretion. At June 30, 2016, we have accrued approximately $100 thousand of cost sharing expenses of clinical studies for product line extensions (additional strengths) of Oxaydo for the United States under the Egalet Agreement and approximately $200 thousand of cost sharing expenses of the FDA required post-marketing study for Oxaydo under the Egalet Agreement.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
