Accounting Policies [Abstract]
BUSINESS, PRESENTATION, AND RECENT ACCOUNTING PRONOUNCEMENTS	1. BUSINESS, PRESENTATION, AND RECENT ACCOUNTING PRONOUNCEMENTS Overview ANI Pharmaceuticals, Inc. and its consolidated subsidiaries, ANIP Acquisition Company and ANI Pharmaceuticals Canada Inc. (together, “ANI,” the “Company,” “we,” “us,” or “our”) is an integrated specialty pharmaceutical company focused on delivering value to our customers by developing, manufacturing, and marketing high quality branded and generic prescription pharmaceuticals. We focus on niche and high barrier to entry opportunities including controlled substances, anti-cancer (oncolytics), hormones and steroids, and complex formulations. Our three pharmaceutical manufacturing facilities, of which two are located in Baudette, Minnesota and one is located in Oakville, Ontario are together capable of producing oral solid dose products, as well as semi-solids, liquids and topicals, controlled substances, and potent products that must be manufactured in a fully-contained environment. Our strategy is to use our assets to develop, acquire, manufacture, and market branded and generic specialty prescription pharmaceuticals. By executing this strategy, we believe we will be able to continue to grow our business, expand and diversify our product portfolio, and create long-term value for our investors. Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In our opinion, the accompanying unaudited interim condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly our financial position, results of operations, comprehensive (loss)/income, and cash flows. The consolidated balance sheet at December 31, 2018, has been derived from audited financial statements of that date. The unaudited interim condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the United States Securities and Exchange Commission. We believe that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited financial statements and notes previously distributed in our Annual Report on Form 10-K for the year ended December 31, 2018. Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of ANI Pharmaceuticals, Inc. and its subsidiaries. All intercompany accounts and transactions are eliminated in consolidation. Foreign Currency The Company has a subsidiary located in Canada. The subsidiary conducts its transactions in U.S. dollars and Canadian dollars, but its functional currency is the U.S. dollar. The results of any non-U.S. dollar transactions are remeasured in U.S. dollars at the applicable exchange rates during the period and resulting foreign currency transaction gains and losses are included in the determination of net income. Our loss on transactions determined in foreign currencies was immaterial for the quarter ended March 31, 2019. Unless otherwise noted, all references to “$” or “dollar” refer to the U.S. dollar. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. In the accompanying consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, revenue recognition, allowance for doubtful accounts, variable consideration determined based on accruals for chargebacks, administrative fees and rebates, government rebates, returns and other allowances, allowance for inventory obsolescence, valuation of financial instruments and intangible assets, accruals for contingent liabilities, fair value of long-lived assets, income tax provision, deferred taxes and valuation allowance, determination of right-of-use assets and lease liabilities, purchase price allocations, and the depreciable lives of long-lived assets. Because of the uncertainties inherent in such estimates, actual results may differ from those estimates. Management periodically evaluates estimates used in the preparation of the financial statements for reasonableness. Leases At the inception of a contract we determine if the arrangement is, or contains, a lease. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Rent expense is recognized on a straight-line basis over the lease term. We have made certain accounting policy elections whereby we (i) do not recognize ROU assets or lease liabilities for short-term leases (those with original terms of 12-months or less) and (ii) combine lease and non-lease elements of our operating leases. Operating lease ROU assets are included in other non-current assets and operating lease liabilities are included in accrued expenses and other and other non-current liabilities in our consolidated balance sheets. As of March 31, 2019, we did not have any finance leases. Geographic Information Based on the distinct nature of our operations, our internal management structure, and the financial information that is evaluated regularly by our Chief Operating Decision Maker, we determined that we operate in one reportable segment. Our operations are located in the United States and Canada. The following table depicts the Company’s revenue by geographic operations during the following periods: (in thousands) Three Months Ended Location of Operations March 31, 2019 March 31, 2018 United States $ 50,900 $ 46,483 Canada 1,987 - Total Revenue $ 52,887 $ 46,483 The following table depicts the Company’s property and equipment, net according to geographic location as of: (in thousands) March 31, 2019 December 31, 2018 United States 24,727 $ 24,437 Canada 13,698 13,653 Total property and equipment, net $ 38,425 $ 38,090 Recent Accounting Pronouncements Recent Accounting Pronouncements Not Yet Adopted In November 2018, the Financial Accounting Standards Board (“FASB”) issued guidance clarifying that certain transactions between collaborative arrangement participants should be accounted for revenue under Accounting Standards Codification Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. The guidance is effective for reporting periods beginning after December 15, 2019, including interim periods within that fiscal year. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the impact, if any, that the adoption of this guidance will have on our consolidated financial statements. In August 2018, the FASB issued guidance modifying the disclosure requirements on fair value measurements. The amendments add, modify, and eliminate certain disclosure requirements on fair value measurements. The guidance is effective for reporting periods beginning after December 15, 2019, including interim periods within that fiscal year. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the impact, if any, that the adoption of this guidance will have on our consolidated financial statements. In June 2016, the FASB issued guidance with respect to measuring credit losses on financial instruments, including trade receivables. The guidance eliminates the probable initial recognition threshold that was previously required prior to recognizing a credit loss on financial instruments. The credit loss estimate can now reflect an entity's current estimate of all future expected credit losses. Under the previous guidance, an entity only considered past events and current conditions. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption of certain amendments of this guidance must be applied on a modified retrospective basis and the adoption of the remaining amendments must be applied on a prospective basis. We currently expect that the adoption of this guidance will likely change the way we assess the collectability of our receivables and recoverability of other financial instruments. We have not yet begun to evaluate the specific impacts of this guidance. We have evaluated all other issued and unadopted Accounting Standards Updates and believe the adoption of these standards will not have a material impact on our condensed consolidated statements of operations, comprehensive (loss)/income, balance sheets, or cash flows. Recently Adopted Accounting Pronouncements In October 2018, the FASB issued guidance for accounting for derivatives and hedging. The guidance provides for the inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index swap rate as a benchmark interest rate for hedge accounting purposes. In July 2017, the Financial Conduct Authority in the United Kingdom announced that it would phase out London Interbank Offered Rate (“LIBOR”) as a benchmark by the end of 2021. As a result, the U.S. Federal Reserve identified the SOFR as its preferred alternative reference rate, calculated with a broad set of short-term repurchase agreements backed by treasury securities. Amounts drawn under our five-year senior secured credit facility bear interest rates in relation to LIBOR, and our interest rate swap is designated in LIBOR. The guidance was effective for reporting periods beginning after December 15, 2018 and early adoption was permitted. We adopted this guidance as of January 1, 2019 on a prospective basis. The adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2018, the Securities and Exchange Commission (“SEC”) adopted the final rule amending certain disclosure requirements that have become redundant, duplicative, overlapping, outdated, or superseded. In addition, the amendments expand the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The rule was effective on November 5, 2018 and was effective for the quarter that began after the effective date. The adoption of this guidance resulted in the inclusion of the statement of changes stockholder’s equity in our interim financial statement filings. In June 2018, the FASB issued guidance simplifying the accounting for nonemployee stock-based compensation awards. The guidance aligns the measurement and classification for employee stock-based compensation awards to nonemployee stock-based compensation awards. Under the guidance, nonemployee awards will be measured at their grant date fair value. Upon transition, the existing nonemployee awards will be measured at fair value as of the adoption date. The guidance was effective for reporting periods beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption was permitted, including adoption in an interim period. We adopted this guidance as of January 1, 2019. The adoption of this guidance did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued guidance for accounting for leases. The guidance requires lessees to recognize assets and liabilities related to long-term leases on the balance sheet and expands disclosure requirements regarding leasing arrangements. In July 2018, the FASB issued additional guidance, which offers a transition option to entities adopting the new lease standards. Under the transition option, entities can elect to apply the new guidance using a modified retrospective approach at the beginning of the year in which the new lease standard is adopted, rather than to the earliest comparative period presented in their financial statements. The guidance was effective for reporting periods beginning after December 15, 2018 and early adoption was permitted. The guidance was adopted on a modified retrospective basis and provides for certain practical expedients. We adopted this guidance effective January 1, 2019 using the following practical expedients:  we did not reassess if any expired or existing contracts are or contain leases;  we did not reassess the classification of any expired or existing leases. Additionally, we made ongoing accounting policy elections whereby we (i) do not recognize right-of-use assets or lease liabilities for short-term leases (those with original terms of 12 -months or less) and (ii) combine lease and non-lease elements of our operating leases. Upon adoption of the new guidance on January 1, 2019, we recognized a right-of-use asset of approximately $0.5 million, which was reduced by approximately $10 thousand of net prepaid rents at the date of adoption, along with a lease liability of approximately $0.5 million. We also recognized total deferred tax assets of approximately $0.1 million and deferred tax liabilities of approximately $0.1 million related to book-tax basis differences. The net effect of the adoption resulted in a cumulative effect adjustment to retained earnings on January 1, 2019 of approximately $2 thousand.

REVENUE RECOGNITION AND RELATED

Revenue Recognition [Abstract]
REVENUE RECOGNITION AND RELATED ALLOWANCES	2. REVENUE RECOGNITION AND RELATED ALLOWANCES Revenue Recognition We recognize revenue using the following steps:  Identification of the contract, or contracts, with a customer;  Identification of the performance obligations in the contract;  Determination of the transaction price, including the identification and estimation of variable consideration;  Allocation of the transaction price to the performance obligations in the contract; and  Recognition of revenue when we satisfy a performance obligation. We derive our revenues primarily from sales of generic and branded pharmaceutical products. Revenue is recognized when our obligations under the terms of our contracts with customers are satisfied, which generally occurs when control of the products we sell is transferred to the customer. We estimate variable consideration after considering applicable information that is reasonably available. We generally do not have incremental costs to obtain contracts that would otherwise not have been incurred. We do not adjust revenue for the promised amount of consideration for the effects of a significant financing component because our customers generally pay us within 100 days. All revenue recognized in the accompanying unaudited interim condensed consolidated statements of operations is considered to be revenue from contracts with customers. The following table depicts the disaggregation of revenue according to contract type: Products and Services Three Months Ended (in thousands) March 31, 2019 March 31, 2018 Sales of generic pharmaceutical products $ 31,599 $ 23,227 Sales of branded pharmaceutical products 17,543 16,595 Sales of contract manufactured products 2,437 945 Royalties from licensing agreements 577 5,382 Product development services 320 - Other (1) 411 334 Total net revenues $ 52,887 $ 46,483 (1) The following table depicts revenue recognized during the following periods: Timing of Revenue Recognition Three Months Ended (in thousands) March 31, 2019 March 31, 2018 Performance obligations transferred at a point in time $ 52,567 $ 46,483 Performance obligations transferred over time 320 - Total $ 52,887 $ 46,483 In the three months ended March 31, 2019 and 2018, we did not incur, and therefore did not defer, any material incremental costs to obtain contracts. We recognized a decrease of $0.6 million Revenue from Sales of Generic and Branded Pharmaceutical Products Product sales consists of sales of our generic and brand pharmaceutical products. Our sole performance obligation in our contracts is to provide pharmaceutical products to customers. Our products are sold at pre-determined standalone selling prices and our performance obligation is considered to be satisfied when control of the product is transferred to the customer. Control is transferred to the customer upon delivery of the product to the customer, as our pharmaceutical products are sold on an FOB destination basis and because inventory risk and risk of ownership passes to the customer upon delivery. Payment terms for these sales are generally less than 100 days. Sales of our pharmaceutical products are subject to variable consideration due to chargebacks, government rebates, returns, administrative and other rebates, and cash discounts.

Our performance obligation is to manufacture and provide pharmaceutical products to customers, typically pharmaceutical companies. The contract manufactured products are sold at pre-determined standalone selling prices and our performance obligations are considered to be satisfied when control of the product is transferred to the customer. Control is transferred to the customer when the product leaves our dock to be shipped to the customer, as our pharmaceutical products are sold on an FOB shipping point basis and the inventory risk and risk of ownership passes to the customer at that time. Payment terms for these sales are generally less than two months. We estimate returns based on historical experience. Historically, we have not had material returns for contract manufactured products. As of March 31, 2019, the value of our unsatisfied performance obligations (or backlog) was $6.4 million, which consists of firm orders for contract manufactured products, for which our performance obligations remain unsatisfied and for which the related revenue has yet to be recognized. We anticipate satisfying these performance obligations within six months. Royalties from Licensing Agreements From time to time, we enter into transition agreements with the sellers of products we acquire, under which we license to the seller the right to sell the acquired products. Therefore, we recognize the revenue associated with sales of the underlying products as royalties. Because these royalties are sales-based, we recognize the revenue when the underlying sales occur, based on sales and gross profit information received from the sellers. Upon full transition of the products and upon launching the products under our own labels, we recognize revenue for the products as sales of generic or branded pharmaceutical products, as described above. We receive royalties from a license for patent rights initially owned by Cell Genesys, Inc., which merged with BioSante in 2009. The royalties are the results of sales and milestones related to the Yescarta® product. We recognize revenue for sales-based royalties when the underlying sales occur. We estimate variable consideration related to milestones, which requires significant judgment. Product Development Services Revenue We provide product development services to customers, which are performed over time. These services primarily relate to the technical transfer of products to our facility in Oakville, Canada. The duration of these technical transfer projects is generally 18 months to three years. Deposits received from these customers are recorded as deferred revenue until revenue is recognized. For contracts with no deposits and for the remainder of contracts with deposits, we invoice customers as our performance obligations are satisfied. We recognize revenue on a percentage of completion basis, which results in contract assets on our balance sheet. As of March 31, 2019, the value of our unsatisfied performance obligations for product development services contracts was $2.1 million. We expect to satisfy these performance obligations in the next 3 to 12 months. Credit Concentration Our customers are primarily wholesale distributors, chain drug stores, group purchasing organizations, and pharmaceutical companies. During the three months ended March 31, 2019, three customers represented 35%, 23%, and 23% of net revenues, respectively. As of March 31, 2019, accounts receivable from these customers totaled 81% of accounts receivable, net. During the three months ended March 31, 2018, three customers represented 34%, 25%, and 20% of net revenues, respectively.

Business Combinations [Abstract]
Business Combination Disclosure	3. BUSINESS COMBINATION Summary On August 6, 2018, our subsidiary, ANI Canada, acquired all the issued and outstanding equity interests of WellSpring, a Canadian company that performs contract development and manufacturing of pharmaceutical products for a purchase price of $18.0 million, subject to certain customary adjustments. Pursuant to these customary adjustments, the total purchase consideration was $16.7 million. The consideration was paid entirely from cash on hand. In conjunction with the transaction, we acquired WellSpring’s pharmaceutical manufacturing facility, laboratory, and offices, its current book of commercial business, as well as an organized workforce. Following the consummation of the transaction, WellSpring was merged into ANI Canada with the resulting entity’s name being ANI Pharmaceuticals Canada Inc. We acquired WellSpring to provide an additional tech transfer site in order to accelerate the re-commercialization of the previously-approved Abbreviated New Drug Applications (“ANDAs”) in our pipeline, to expand our contract manufacturing revenue base, and to broaden our manufacturing capabilities to three manufacturing facilities. Transaction Costs In conjunction with the acquisition, we incurred approximately $1.1 million in transaction costs, all of which were expensed in 2018. Purchase Consideration and Net Assets Acquired The business combination was accounted for using the acquisition method of accounting, with ANI as the accounting acquirer of WellSpring. The acquisition method requires that acquired assets and assumed liabilities be recorded at their fair values as of the acquisition date. The following presents the preliminary allocation of the purchase price to the assets acquired and liabilities assumed on August 6, 2018: (in thousands) Total Purchase Consideration $ 16,687 Cash and cash equivalents 220 Accounts receivable 1,311 Inventories 2,197 Prepaid expenses and other current assets 361 Property and equipment 13,935 Deferred tax assets, net - Goodwill 1,742 Total assets acquired 19,766 Accounts payable and other current liabilities 2,413 Deferred revenue 666 Total liabilties assumed 3,079 Net assets acquired $ 16,687 The net assets were recorded at their estimated fair value. In valuing acquired assets and liabilities, fair value estimates were based primarily on future expected cash flows, market rate assumptions for contractual obligations, and appropriate discount rates. The above allocation of the purchase price is based upon certain preliminary valuations and other analyses that have not been finalized as of the date of this filing. Any changes in the estimated fair values of the net assets recorded for this business combination upon the finalization of more detailed analyses of the facts and circumstances that existed at the date of the transaction may change the allocation of the purchase price. As such, the purchase price allocations for this transaction are preliminary estimates, which may be subject to change within the measurement period. Goodwill is considered an indefinite-lived asset and relates primarily to intangible assets that do not qualify for separate recognition, such as the assembled workforce and synergies between the entities. Goodwill established as a result of the acquisition is not tax deductible in any taxing jurisdiction. There was no value ascribed to any separately identifiable intangible assets. Legacy WellSpring operations generated $2.0 million of revenue and recorded a net loss of $1.2 million for the three months ended March 31, 2019. Pro Forma Condensed Combined Financial Information (unaudited) The following unaudited pro forma condensed combined financial information summarizes the results of operations for the periods indicated as if the WellSpring acquisition had been completed as of January 1, 2017.

Debt Disclosure [Abstract]
INDEBTEDNESS	4. INDEBTEDNESS Credit Facility On December 27, 2018, we refinanced our $125.0 million five-year senior secured credit facility (the “Credit Agreement”) with Citizens Bank, N.A. by entering into an amended and restated Senior Secured Credit Facility (the “Credit Facility”) for up to $265.2 million. The principal new feature of the Credit Facility is a $118.0 million Delayed Draw Term Loan (the “DDTL”), which can only be drawn on in order to pay down the Company’s remaining 3.0% Convertible Senior Notes, which will mature in December 2019. The Credit Facility (and specifically the DDTL) has a subjective acceleration clause in case of a material adverse event. As a result, the remaining 3% Convertible Senior Notes are classified as current in the accompanying unaudited interim condensed consolidated balance sheets. The Credit Facility also extended the maturity of the $72.2 million secured term loan balance (the “Term Loan”) to December 2023. In addition, the Credit Facility increased the previous $50.0 million line of credit (the “Revolver”) to $75.0 million. Also on December 27, 2018, we entered into an interest rate swap arrangement to manage our exposure to changes in LIBOR-based interest rates underlying our refinanced Term Loan (Note 5). The Term Loan includes a repayment schedule, subsequent to which $3.6 million of the loan will be paid in quarterly installments during the 12 months ended March 31, 2020. As a result, $3.6 million of the loan is recorded in current component of borrowing, net of deferred financing in the accompanying unaudited interim condensed consolidated balance sheets. Amounts drawn on the Term Loan and, if drawn upon, the DDTL, bear an interest rate equal to, at our option, either a LIBOR rate plus 1.50% to 2.75% per annum, depending on our total leverage ratio or an alternative base rate plus an applicable base rate margin, which varies within a range of 0.50% to 1.75%, depending our total leverage ratio. We will incur a commitment fee at a rate per annum that varies within a range of 0.25% to 0.50%, depending on our leverage ratio. We will also incur a delayed draw ticking fee at a rate per annum that varies within a range of 0.25% to 0.50%, depending on our leverage ratio. The Credit Facility is secured by a lien on substantially all of ANI Pharmaceuticals, Inc.’s and its principal domestic subsidiary’s assets and any future domestic subsidiary guarantors’ assets. The Credit Facility imposes financial covenants consisting of a maximum total leverage ratio, which initially shall be no greater than 3.75 to 1.00 and a minimum fixed charge coverage ratio, which shall be greater than or equal to 1.25 to 1.00. The primary non-financial covenants under the Credit Facility limit, subject to various exceptions, our ability to incur future indebtedness, to place liens on assets, to pay dividends or make other distributions on our capital stock, to repurchase our capital stock, to conduct acquisitions, to alter our capital structure, and to dispose of assets outside the normal course of business . The carrying value of the current and non-current components of the Term Loan as of March 31, 2019 and December 31, 2018 are: Current (in thousands) March 31, 2019 December 31, 2018 Current borrowing on secured term loan $ 3,609 $ 3,609 Deferred financing costs (366 ) (353 ) Current component of non-current borrowing, net of deferred financing costs $ 3,243 $ 3,256 Non-current (in thousands) March 31, 2019 December 31, 2018 Non-current borrowing on secured term loan $ 67,676 $ 68,578 Deferred financing costs (1,175 ) (1,282 ) Non-current borrowing, net of deferred financing costs and current borrowing component $ 66,501 $ 67,296 The refinancing of the Term Loan was accounted for as a modification of our previous term loan and consequently, the remaining balance of the deferred issuance costs related to the previous term loan are included with the lenders fees associated with the refinance of the Term Loan and amortized as interest expense over the life of the Term Loan using the effective interest method. Fees to third parties associated with the refinance of the Term Loan were recognized as other (expense)/income, net in the accompanying unaudited interim condensed consolidated statements of operations. The refinancing of the Revolver was accounted for as a modification of our previous revolving credit facility and consequently, the remaining balance of the deferred issuance costs related to the previous revolving credit facility are included with the lenders fees and fees to third parties associated with the refinance of the Revolver and amortized as interest expense on a straight-line basis over the life of the Revolver. All issuance costs allocated to the DDTL were deferred and will be amortized as interest expense on a straight-line basis over the five-year term of the DDTL. As of March 31, 2019, we had a $71.3 million balance on the Term Loan. As of March 31, 2019, we had not drawn on the Revolving Credit Facility or DDTL. Of the $1.3 million of deferred debt issuance costs allocated to the Revolving Credit Facility, $0.9 million is included in other assets in the accompanying unaudited interim condensed consolidated balance sheets and $0.3 million is included in prepaid expenses and other current assets in the accompanying unaudited interim condensed consolidated balance sheets. Of the $0.6 million of deferred debt issuance costs allocated to the DDTL, $0.4 million is included in other assets in the accompanying unaudited interim condensed consolidated balance sheets and $0.1 million is included in prepaid expenses and other current assets in the accompanying unaudited interim condensed consolidated balance sheets. Of the $1.6 million of deferred debt issuance costs allocated to the Term Loan, $0.4 million is classified as a direct deduction to the current portion of the Term Loan and is included in current component of borrowing, net of deferred financing costs in the accompanying unaudited interim condensed consolidated balance sheets and $1.2 million is classified as a The contractual maturity of our Term Loan is as follows for the years ending December 31: (in thousands) 2019 (remainder of the year) $ 2,707 2020 3,609 2021 5,414 2022 5,414 2023 54,141 Total $ 71,285 Convertible Senior Notes In December 2014, we issued $143.8 million of our a registered public offering. After deducting the underwriting discounts and commissions and other expenses (including the net cost of the bond hedge and warrant, discussed below), the net proceeds from the offering were approximately $122.6 million. The Notes pay 3.0% interest semi-annually in arrears on June 1 and December 1 of each year, starting on June 1, 2015, and are due December 1, 2019. In December 2018, we entered into separate, privately negotiated agreements with certain holders of our Notes and repurchased $25.0 million of our outstanding Notes. We accounted for the repurchase as an extinguishment of the portion of the Notes and recognized a loss on extinguishment of $0.5 million, which was recorded in other (expense)/income, net in the accompanying unaudited interim condensed consolidated statements of operations. At the same time, we unwound a corresponding portion of the bond hedge and warrant, which are described in further detail below. As a result of unwinding this portion of the bond hedge and warrant, we received a net amount of $0.4 million. The repurchase of the Notes and the unwinding of the bond hedge and warrant resulted in a $1.7 million net reduction to additional paid-in capital (“APIC”) in the accompanying unaudited interim condensed consolidated balance sheets. The remaining Notes are convertible into 1,709,002 shares of common stock, based on an initial conversion price of $69.48 per share. The Notes are convertible at the option of the holder (i) during any calendar quarter beginning after March 31, 2015, if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day, (ii) during the five business days after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each trading day of such period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; and (iii) on or after June 1, 2019 until the second scheduled trading day immediately preceding the maturity date. Upon conversion by the holders, we may elect to settle such conversion in shares of our common stock, cash, or a combination thereof. As a result of our cash conversion option, we separately accounted for the value of the embedded conversion option as a debt discount (with an offset to APIC) of $33.6 million. The value of the embedded conversion option was determined based on the estimated fair value of the debt without the conversion feature, which was determined using market comparables to estimate the fair value of similar non-convertible debt (Note 13); the debt discount is being amortized as additional non-cash interest expense using the effective interest method over the term of the Notes. Offering costs of $5.5 million were allocated to the debt and equity components in proportion to the allocation of proceeds to the components, as deferred financing costs and equity issuance costs, respectively. The deferred financing costs of $4.2 million are being amortized as additional non-cash interest expense using the straight-line method over the term of the debt, since this method was not significantly different from the effective interest method. Pursuant to guidance issued by the FASB in April 2015, we have classified the deferred financing costs as a direct deduction to the net carrying value of our Notes. The $1.3 million portion allocated to equity issuance costs was charged to APIC. A portion of the offering proceeds was used to simultaneously enter into “bond hedge” (or purchased call) and “warrant” (or written call) transactions with an affiliate of one of the offering underwriters (collectively, the “Call Option Overlay”). We entered into the Call Option Overlay to synthetically raise the initial conversion price of the Notes to $96.21 per share and reduce the potential common stock dilution that may arise from the conversion of the Notes. The exercise price of the bond hedge is $69.48 per share and the exercise price of the warrant is $96.21 per share of our common stock. Because the bond hedge and warrant are both indexed to our common stock and otherwise would be classified as equity, we recorded both elements as equity, resulting in a net reduction to APIC of $15.6 million. After the repurchase of $25.0 million of our outstanding Notes and the unwinding of the corresponding portion of the bond hedge and warrant, our remaining bond hedge had an underlying 1,709,002 common shares as of March 31, 2019 and the remaining warrant had an underlying 1,709,002 common shares as of March 31, 2019. The carrying value of the Notes is as follows as of: (in thousands) March 31, 2019 December 31, 2018 Principal amount $ 118,750 $ 118,750 Unamortized debt discount (4,135 ) (5,648 ) Deferred financing costs (465 ) (639 ) Net carrying value $ 114,150 $ 112,463 We had accrued interest of $1.2 million and $0.3 million related to the Notes recorded in accrued expenses, other in our consolidated balance sheets at March 31, 2019 and December 31, 2018, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENT AND HEDGING ACTIVITY	5. DERIVATIVE FINANCIAL INSTRUMENT AND HEDGING ACTIVITY We use derivative financial instruments to hedge our exposure to interest rate risks. All derivative financial instruments are recognized as either assets or liabilities at fair value on the consolidated balance sheet and are classified as current or non-current based on the scheduled maturity of the instrument. When we enter into a hedge arrangement and intend to apply hedge accounting, we formally document the hedge relationship and designate the instrument for financial reporting purposes as a fair value hedge, a cash flow hedge, or a net investment hedge. When we determine that a derivative financial instrument qualifies as a cash flow hedge and is effective, the changes in fair value of the instrument are recorded in accumulated other comprehensive loss, net of tax in our consolidated balance sheets and will be reclassified to earnings when the hedged item affects earnings. In April 2018, we entered into an interest rate swap arrangement, which was considered a derivative financial instrument, with Citizens Bank, N.A. to manage our exposure to changes in LIBOR-based interest rates underlying our previous term loan. The interest rate swap hedged the variable cash flows associated with the borrowings under our previous term loan, effectively providing a fixed rate of interest throughout the life of the previous term loan. In December 2018, we refinanced our previous Credit Agreement and, as part of that refinancing, extended the maturity of our $72.2 million secured term loan balance to December 2023. At the same time, we terminated the original interest rate swap and entered into a new interest rate swap arrangement, which is also considered a derivative financial instrument, with Citizens Bank, N.A. to manage our exposure to changes in LIBOR-based interest rates underlying our Term Loan. We accounted for the close-out of the original interest rate swap as a termination of the interest rate swap and wrote the interest rate swap liability and accumulated other comprehensive loss balance off as of the date of termination. As there were no excluded components, there was no net impact to the consolidated statement of operations. The interest rate swap hedges the variable cash flows associated with the borrowings under our Term Loan (Note 4), effectively providing a fixed rate of interest throughout the life of our Term Loan. The interest rate swap arrangement with Citizens Bank, N.A became effective on December 27, 2018, with a maturity date of December 27, 2023. The notional amount of the swap agreement at inception was $72.2 million and will decrease in line with our Term Loan. As of March 31, 2019, the notional amount of the interest rate swap was $71.3 million. The interest rate swap has a weighted average fixed rate of 2.60% and has been designated as an effective cash flow hedge and therefore qualifies for hedge accounting. As of March 31, 2019, the fair value of the interest rate swap liability was valued at $1.2 million and was recorded in other liabilities in the accompanying unaudited interim condensed consolidated balance sheets. As of March 31, 2019, $ 1.0 million, the fair value of the interest rate swap net of tax, was recorded in accumulated other comprehensive loss, net of tax in the accompanying unaudited interim condensed consolidated balance sheets. During the three months ended March 31, 2019, changes in the fair value of the interest rate swap of $ 0.6 million, net of tax, was recorded in accumulated other comprehensive loss, net of tax in our unaudited interim condensed consolidated statements of comprehensive In February 2019, we entered into an interest rate swap with Citizens Bank, N.A. to manage our exposure to changes in LIBOR-based interest rates underlying our DDTL. The notional amount of the interest rate swap is $118.0 million and will have a cash and interest impact beginning in December 2019. The interest rate swap provides an effective fixed rate of 2.47% and has been designated as an effective cash flow hedge and therefore qualifies for hedge accounting. As of March 31, 2019, the fair value of the interest rate swap liability was valued at $1.5 million and was recorded in other liabilities in the accompanying unaudited interim condensed consolidated balance sheets. As of March 31, 2019, $1.2 million, the fair value of the interest rate swap net of tax, was recorded in accumulated other comprehensive loss, net of tax in the accompanying unaudited interim condensed consolidated balance sheets. During the three months ended March 31, 2019, changes in the fair value of the interest rate swap of $1.2 million, net of tax, was recorded in accumulated other comprehensive loss, net of tax in our unaudited interim condensed consolidated statements of comprehensive

Earnings Per Share [Abstract]
EARNINGS PER SHARE	6. EARNINGS PER SHARE Basic earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. For periods of net income, and when the effects are not anti-dilutive, we calculate diluted earnings per share by dividing net income available to common shareholders by the weighted-average number of shares outstanding plus the impact of all potential dilutive common shares, consisting primarily of common stock options, shares to be purchased under our Employee Stock Purchase Plan (“ESPP”), unvested restricted stock awards, stock purchase warrants, and any conversion gain on our Notes (Note 4), using the treasury stock method. For periods of net loss, diluted loss per share is calculated similarly to basic loss per share. Our unvested restricted shares contain non-forfeitable rights to dividends, and therefore are considered to be participating securities; in periods of net income, the calculation of basic and diluted earnings per share excludes from the numerator net income attributable to the unvested restricted shares, and excludes the impact of those shares from the denominator. For purposes of determining diluted earnings per share, we have elected a policy to assume that the principal portion of the Notes (Note 4) is settled in cash. As such, the principal portion of the Notes has no effect on either the numerator or denominator when determining diluted earnings per share. Any conversion gain is assumed to be settled in shares and is incorporated in diluted earnings per share using the treasury method. The warrants issued in conjunction with the issuance of the Notes (Note 4) are considered to be dilutive when they are in-the-money relative to our average stock price during the period; the bond hedge purchased in conjunction with the issuance of the Notes is always considered to be anti-dilutive. Earnings per share for the three months ended March 31, 2019 and 2018 are calculated for basic and diluted earnings per share as follows: Basic Diluted (in thousands, except per share amounts) Three Months Ended March 31, Three Months Ended March 31, 2019 2018 2019 2018 Net income $ 449 $ 2,250 $ 449 $ 2,250 Net income allocated to restricted stock (9 ) (13 ) (9 ) (13 ) Net income allocated to common shares $ 440 $ 2,237 $ 440 $ 2,237 Basic Weighted-Average Shares Outstanding 11,747 11,589 11,747 11,589 Dilutive effect of stock options and ESPP 76 117 Diluted Weighted-Average Shares Outstanding 11,823 11,706 Earnings Per Share $ 0.04 $ 0.19 $ 0.04 $ 0.19 The number of anti-dilutive shares, which have been excluded from the computation of diluted earnings per share, including the shares underlying the Notes, was 4.1 million and 4.6 million for the three months ended March 31, 2019 and 2018, respectively. Anti-dilutive shares consist of out-of-the-money Class C Special stock, out-of-the-money common stock options, common stock options that are anti-dilutive when calculating the impact of the potential dilutive common shares using the treasury stock method, underlying shares related to out-of-the-money bonds issued as convertible debt, and out-of-the-money warrants exercisable for common stock.

GOODWILL AND INTANGIBLE ASSETS	9. GOODWILL AND INTANGIBLE ASSETS Goodwill As a result of our 2013 merger with BioSante Pharmaceuticals, Inc. (“BioSante”), we recorded goodwill of $1.8 million. As a result of our acquisition of WellSpring, we recorded additional goodwill of $1.7 million in 2018. We assess the recoverability of the carrying value of goodwill as of October 31 st Definite-lived Intangible Assets Acquisition of Abbreviated New Drug Applications In March 2019, we entered into an agreement with Teva Pharmaceutical Industries Ltd. to purchase a basket of ANDAs for 35 previously-marketed generic drug products for $2.5 million in cash. The transaction closed in March 2019 and we made the $2.5 million payment using cash on hand. We also capitalized $10 thousand of costs directly related to the transaction. We accounted for this transaction as an asset purchase. The $2.5 million of ANDAs are being amortized in full over their estimated useful lives of 10 years. Please see Note 13 for further details regarding the transaction. In January 2019, we entered into an amendment to three asset purchase agreements (the “Asset Purchase Agreement Amendment”) with Teva Pharmaceuticals USA, Inc. (“Teva”). Under the terms of the Asset Purchase Agreement Amendment, all royalty obligations of the Company owed to Teva with respect to products associated with ten ANDAs under the original asset purchase agreements ceased being effective as of December 31, 2018. As consideration for the termination of such future royalty obligations, we paid Teva a sum of $16.0 million using cash on hand. Upon the payment of $16.0 million, the purchase price of each basket of ANDAs was increased In April 2018, we entered into an agreement with Impax Laboratories, Inc. (now Amneal Pharmaceuticals, Inc., or “Amneal”) to purchase the approved ANDAs for three previously-commercialized generic drug products, the approved ANDAs for two generic drug products that have not yet been commercialized, the development package for one generic drug product, a license, supply, and distribution agreement for a generic drug product with an ANDA that is pending approval, and certain manufacturing equipment required to manufacture one of the products, for $2.3 million in cash up front. The transaction closed in May 2018 and we made the $2.3 million payment using cash on hand. We also capitalized $0.1 million of costs directly related to the transaction. We accounted for this transaction as an asset purchase. The $1.0 million acquired ANDA intangible assets are being amortized in full over their estimated useful lives of 10 years. Please see Note 13 for further details regarding the transaction. In April 2018, we entered into an agreement with IDT Australia, Limited to purchase the ANDAs for 23 previously-marketed generic drug products and API for four of the acquired products for $2.7 million in cash and a single-digit royalty on net profits from sales of one of the products. The transaction closed in April 2018 and we made the $2.7 million payment using cash on hand. We also capitalized $18 thousand of costs directly related to the transaction. We accounted for this transaction as an asset purchase. The $2.5 million acquired ANDA intangible assets are being amortized in full over their estimated useful lives of 10 years. Please see Note 13 for further details regarding the transaction. The components of net definite-lived intangible assets are as follows: (in thousands) March 31, 2019 December 31, 2018 Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Weighted Average Amortization Period Acquired ANDA intangible assets $ 64,704 $ (25,321 ) $ 46,194 $ (17,093 ) 10.0 years NDAs and product rights 230,974 (68,505 ) 230,974 (62,222 ) 10.0 years Marketing and distribution rights 10,423 (7,532 ) 10,423 (7,051 ) 4.7 years Non-compete agreement 624 (267 ) 624 (245 ) 7.0 years $ 306,725 $ (101,625 ) $ 288,215 $ (86,611 ) Definite-lived intangible assets are stated at cost, net of amortization, generally using the straight-line method over the expected useful lives of the intangible assets. In the case of certain NDA and product rights assets, we use an accelerated amortization method to better match the anticipated economic benefits expected to be provided. Amortization expense was $15.0 million and $7.9 million for the three months ended March 31, 2019 and 2018, respectively. We test for impairment of definite-lived intangible assets when events or circumstances indicate that the carrying value of the assets may not be recoverable. No such triggering events were identified during the three months ended March 31, 2019 and 2018 and therefore no impairment loss was recognized in the three months ended March 31, 2019 and 2018. Expected future amortization expense is as follows: (in thousands) 2019 (remainder of the year) $ 25,209 2020 33,130 2021 31,684 2022 28,279 2023 27,531 2024 and thereafter 59,267 Total $ 205,100

Income Tax Disclosure [Abstract]
INCOME TAXES	11. INCOME TAXES We use the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that such tax rate changes are enacted. The measurement of a deferred tax asset is reduced, if necessary, by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized. We have provided a valuation allowance against certain of our state net operating loss We use a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. We have not identified any uncertain income tax positions that could have a material impact on the consolidated financial statements. We recognize interest and penalties accrued on any unrecognized tax exposures as a component of income tax expense; we did not have any such amounts accrued as of March 31, 2019 and December 31, 2018. We are subject to taxation in various U.S. jurisdictions and all of our income tax returns remain subject to examination by tax authorities due to the availability of NOL carryforwards. For interim periods, we recognize an income tax provision/(benefit) based on our estimated annual effective tax rate, calculated on a worldwide consolidated basis, expected for the entire year. If we project taxable losses in any specific taxing jurisdiction, those losses are excluded from the calculation of the worldwide estimated annual effective tax rate and a resulting tax benefit is not recognized. The interim annual estimated effective tax rate is based on the statutory tax rates then in effect, as adjusted for estimated changes in temporary and estimated permanent differences, and excludes certain discrete items whose tax effect, when material, is recognized in the interim period in which they occur. These changes in temporary differences, permanent differences, and discrete items result in variances to the effective tax rate from period to period. We also have elected to exclude the impacts from significant pre-tax non-recognized subsequent events from our interim estimated annual effective rate until the period in which they occur. Our estimated annual effective tax rate changes throughout the year as our on-going estimates of pre-tax income, changes in temporary differences, and permanent differences are revised, and as discrete items occur. Global Intangible Low-Taxed Income (“GILTI”), as defined in the Tax Cuts and Jobs Act of 2017, generated from our recently acquired Canadian operations is subject to U.S. taxes, with certain defined exemptions, thresholds and credits. For financial reporting purposes we have elected to treat GILTI inclusions as a period cost. The estimated consolidated effective tax rate for the three months ended March 31, 2019, calculated after excluding the taxable losses projected in our Canadian operations for which no tax benefit can be recognized, was 22.0% of pre-tax income reported in the period, calculated based on the estimated annual effective rate anticipated for the year ending December 31, 2019 plus the effects of certain discrete items occurring in the third quarter. Our effective tax rate for the three months ended March 31, 2019 was impacted primarily by the discrete impact of current period awards of stock-based compensation, stock option exercises, and disqualifying dispositions of incentive stock options, all of which impact the consolidated effective rate in the period in which they occur. The estimated consolidated effective tax rate for the three months ended March 31, 2018 was 20.8% of pre-tax income reported in the period, calculated based on the estimated annual effective rate anticipated for the year ending December 31, 2018 plus the effects of certain discrete items occurring in the first quarter. Our effective tax rate was impacted by the discrete impact of current period awards of stock-based compensation, stock option exercises, and disqualifying dispositions of incentive stock options, all of which impact the consolidated effective rate in the period in which they occur.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	12. COMMITMENTS AND CONTINGENCIES Operating Leases All our existing leases as of March 31, 2019 are classified as operating leases. As of March 31, 2019, we have ten material operating leases for facilities and office equipment with remaining terms expiring from 2021 through 2024 and a weighted average remaining lease term of 3.1 years. Many of our existing leases have fair value renewal options, none of which are considered certain of being exercised or included in the minimum lease term. Discount rates used in the calculation of our lease liability ranged between 4.02% and 8.95%. Rent expense for the three months ended March 31, 2019 consisted of the following: (in thousands) Operating lease costs $ 44 Variable lease costs 13 Total lease costs $ 57 A maturity analysis of our operating leases follows: (in thousands) Future payments: 2019 (remainder of the year) $ 138 2020 190 2021 129 2022 93 2023 36 2024 and thereafter 2 Total $ 588 Discount (42 ) Lease liability 546 Current lease liability (165 ) Non-current lease liability $ 381 Government Regulation Our products and facilities are subject to regulation by a number of federal and state governmental agencies. The FDA, in particular, maintains oversight of the formulation, manufacture, distribution, packaging, and labeling of all of our products. The Drug Enforcement Administration (“DEA”) maintains oversight over our products that are controlled substances. Unapproved Products Two of our products, Esterified Estrogen with Methyltestosterone (“EEMT”) and Opium Tincture, are marketed without approved NDAs or ANDAs. During the three months ended March 31, 2019 and 2018, net revenues for these products totaled $5.4 million and $5.6 million, respectively. The FDA's policy with respect to the continued marketing of unapproved products is stated in the FDA's September 2011 Compliance Policy Guide Sec. 440.100 titled “Marketed New Drugs without Approved NDAs or ANDAs.” Under this policy, the FDA has stated that it will follow a risk-based approach with regard to enforcement against such unapproved products. The FDA evaluates whether to initiate enforcement action on a case-by-case basis, but gives higher priority to enforcement action against products in certain categories, such as those marketed as unapproved drugs with potential safety risks or that lack evidence of effectiveness. We believe that, so long as we comply with applicable manufacturing standards, the FDA will not take action against us under the current enforcement policy. There can be no assurance, however, that the FDA will continue this policy or not take a contrary position with any individual product or group of products. If the FDA were to take a contrary position, we may be required to seek FDA approval for these products or withdraw such products from the market. If we decide to withdraw the products from the market, our net revenues for generic pharmaceutical products would decline materially, and if we decide to seek FDA approval, we would face increased expenses and might need to suspend sales of the products until such approval was obtained, and there are no assurances that we would receive such approval. In addition, one group of products that we manufacture on behalf of a contract customer is marketed by that customer without an approved NDA. If the FDA took enforcement action against such customer, the customer may be required to seek FDA approval for the group of products or withdraw them from the market. Our contract manufacturing revenues for these unapproved products for the three months ended March 31, 2019 and 2018 were $0.6 million and $0.4 million, respectively. We receive royalties on the net sales of a group of contract-manufactured products, which are marketed by the contract customer without an approved NDA. If the FDA took enforcement action against such customer, the customer may be required to seek FDA approval for the group of products or withdraw them from the market. Our royalties on the net sales of these unapproved products for the three months ended March 31, 2019 and 2018 were less than 1% of total revenues. Louisiana Medicaid Lawsuit On September 11, 2013, the Attorney General of the State of Louisiana filed a lawsuit in Louisiana state court against numerous pharmaceutical companies, including us, under various state laws, alleging that each defendant caused the state’s Medicaid agency to provide reimbursement for drug products that allegedly were not approved by the FDA and therefore allegedly not reimbursable under the federal Medicaid program. The lawsuit relates to three cough and cold prescription products manufactured and sold by our former Gulfport, Mississippi operation, which was sold in September 2010. Through its lawsuit, the state seeks unspecified damages, statutory fines, penalties, attorneys’ fees, and costs. While we cannot predict the outcome of the lawsuit at this time, we could be subject to material damages, penalties, and fines. We intend to vigorously defend against all claims in the lawsuit. Civil Action In November of 2017, we were served with a complaint filed by Arbor Pharmaceuticals, LLC, in the United States District Court, District of Minnesota. The complaint alleges false advertising and unfair competition in violation of Section 43(a) of the Lanham Act, Section 1125(a) of Title 15 of the United States Code, and Minnesota State law, and seeks injunctive relief and damages. Discovery in this action closed on March 31, 2019, and it is now in the pre-trial motions phase. We intend to defend this action vigorously. Other Commitments and Contingencies All manufacturers of the drug Reglan and its generic equivalent metoclopramide, including ANI, have faced allegations from plaintiffs in various states claiming bodily injuries as a result of ingestion of metoclopramide or its brand name, Reglan, prior to the FDA's February 2009 Black Box warning requirement (“legacy claims”). All these original legacy claims were settled or closed out, including a series of claims in California that were resolved by coordinated proceeding and settlement. At the end of March 2019, we were served with a lawsuit in the Superior Court of California, County of Riverside, adding us as a defendant in a complaint filed in July 2017 that is alleged not to been part of the original settled legacy claims. This new claim as well as the impact of the prior settlements on this claim is currently being evaluated by the Company, its insurers, and its legal counsel. At the present time, we are unable to assess the likely outcome of the case. Our insurance company had assumed the defense of the legacy claims and paid all losses in settlement of the California cases. We cannot provide assurances that the outcome of this new matter will not have an adverse effect on our business, financial condition, and operating results. Furthermore, like all pharmaceutical manufacturers, we may be exposed to other product liability claims in the future, which could limit our coverage under future insurance policies or cause those policies to become more expensive, which could harm our business, financial condition, and operating results. Our ANDA for Erythromycin Ethylsuccinate (“EES”) was originally approved by the FDA on November 27 th On or about September 20, 2017, the Company and certain of its employees were served with search warrants and/or grand jury subpoenas to produce documents and possibly testify relating to a federal investigation of the generic pharmaceutical industry. The Company has been cooperating and intends to continue cooperating with the investigation. However, no assurance can be given as to the timing or outcome of the investigation.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	13. FAIR VALUE DISCLOSURES Fair value is the price that would be received from the sale of an asset or paid to transfer a liability assuming an orderly transaction in the most advantageous market at the measurement date. U.S. GAAP establishes a hierarchical disclosure framework that prioritizes and ranks the level of observability of inputs used in measuring fair value. The inputs used in measuring the fair value of cash and cash equivalents are considered to be level 1 in accordance with the three-tier fair value hierarchy. The fair market values are based on period-end statements supplied by the various banks and brokers that held the majority of our funds. The fair value of short-term financial instruments (primarily accounts receivable, prepaid expenses, accounts payable, accrued expenses, borrowings under lines of credit, and other current liabilities) approximate their carrying values because of their short-term nature. While our Notes are recorded on our accompanying unaudited interim condensed consolidated balance sheets at their net carrying value of $114.2 million as of March 31, 2019, the Notes are being traded on the bond market and their fair value is $130.3 million, based on their closing price on March 31, 2019, a Level 1 input. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Our contingent value rights (“CVRs”), which were granted coincident with our merger with BioSante and expire in June 2023, are considered contingent consideration and are classified as liabilities. As such, the CVRs were recorded as purchase consideration at their estimated fair value, using level 3 inputs, and are marked to market each reporting period until settlement. The fair value of CVRs is estimated using the present value of our projection of the expected payments pursuant to the terms of the CVR agreement, which is the primary unobservable input. If our projection or expected payments were to increase substantially, the value of the CVRs could increase as a result. The present value of the liability was calculated using a discount rate of 15%. We determined that the fair value of the CVRs was immaterial as of March 31, 2019 and December 31, 2018. We also determined that the changes in such fair value were immaterial in the three months ended March 31, 2019 and 2018. In April 2018, we entered into an interest rate swap arrangement (Note 5), with Citizens Bank, N.A. to manage our exposure to the variable interest rate on our previous term loan. The notional amount of this interest rate swap was set to match the balance of our previous term loan. The fair value of our interest rate swap was estimated based on the present value of projected future cash flows using the LIBOR forward rate curve. The model used to value the interest rate swap included inputs of readily observable market data, a Level 2 input. In December 2018, we refinanced our previous Credit Agreement and, as part of that refinancing, extended the maturity of our $72.2 million secured term loan balance to December 2023. At the same time, we closed out the original interest rate swap and entered into a new interest rate swap arrangement (Note 5) to manage our exposure to the variable interest rate on our Term Loan (Note 4). The notional amount of our interest rate swap was set to match the balance of our Term Loan. The fair value of our interest rate swap is estimated based on the present value of projected future cash flows using the LIBOR forward rate curve. The model used to value the interest rate swap includes inputs of readily observable market data, a Level 2 input. As described in detail in Note 5, the fair value of the interest rate swap was a $1.2 million liability at March 31, 2019. In February 2019, we entered into an interest rate swap arrangement (Note 5), with Citizens Bank, N.A. to manage our exposure to changes in LIBOR-based interest rates underlying our DDTL (Note 4). The fair value of our interest rate swap was estimated based on the present value of projected future cash flows using the LIBOR forward rate curve. The model used to value the interest rate swap included inputs of readily observable market data, a Level 2 input. As described in detail in Note 5, the fair value of the interest rate swap was a $1.5 million liability at March 31, 2019. The following table presents our financial assets and liabilities accounted for at fair value on a recurring basis as of March 31, 2019 and December 31, 2018, by level within the fair value hierarchy: (in thousands) Description Fair Value at March 31, 2019 Level 1 Level 2 Level 3 Liabilities Interest rate swap $ 2,728 $ - $ 2,728 $ - CVRs $ - $ - $ - $ - Description Fair Value at December 31, 2018 Level 1 Level 2 Level 3 Liabilities Interest rate swap $ 496 $ - $ 496 $ - CVRs $ - $ - $ - $ - Financial Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis We do not have any financial assets and liabilities that are measured at fair value on a non-recurring basis. Non-Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis We do not have any non-financial assets and liabilities that are measured at fair value on a recurring basis. Non-Financial Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis We measure our long-lived assets, including property, plant, and equipment, ROU assets, intangible assets, and goodwill, at fair value on a non-recurring basis. These assets are recognized at fair value when they are deemed to be other-than-temporarily impaired. No such fair value impairment was recognized in the three months ended March 31, 2019 and 2018. Please see Note 3 for discussion of assets and liabilities acquired in the acquisition of WellSpring. Acquired Non-Financial Assets Measured at Fair Value In March 2019, we entered into an agreement with Teva Pharmaceutical Industries Ltd. to purchase a basket of ANDAs for 35 previously-marketed generic drug products for $2.5 million in cash (Note 9). We made the $2.5 million cash payment using cash on hand and capitalized $10 thousand of costs directly related to the asset purchase. We accounted for this transaction as an asset purchase. The $2.5 million of ANDAs were recorded at their relative fair value, determined using Level 3 unobservable inputs. In order to determine the fair value of the product rights intangible assets, we used the present value of the estimated cash flows related to the product rights, using a discount rate of 15%. The ANDAs will be amortized in full over their 10-year useful lives, and will be tested for impairment when events or circumstances indicate that the carrying value of the asset may not be recoverable. No such triggering events were identified during the period from the date of acquisition to March 31, 2019 and therefore no impairment loss was recognized for the three months ended March 31, 2019. In January 2019, we entered into an amendment to asset purchase agreements with Teva related to three purchases of baskets of ANDAs. Under the terms of the Asset Purchase Agreement Amendment, all royalty obligations of the Company owed to Teva with respect to products associated with ten ANDAs under the original asset purchase agreements ceased being effective as of December 31, 2018. As consideration for the termination of such future royalty obligations, we paid Teva a sum of $16.0 million in cash (Note 9). Upon payment of $16.0 million, the purchase price of each basket of ANDAs was increased to reflect the subsequent payment as if that payment had been made on the initial acquisition date. As a result, in addition to increasing the carrying value of the acquired ANDA intangible assets by $9.2 million, we recognized cumulative amortization expense of $6.8 million. The payment was allocated to the three ANDA baskets based on the relative fair value of the ANDA baskets, which were determined using Level 3 unobservable inputs. In order to determine the fair value of the acquired ANDA intangible assets, we used the present value of the estimated cash flows related to the ANDAs, using a discount rate of 12%. The additional carrying value will be amortized over the remaining useful lives of the three ANDA baskets and will be tested for impairment when events or circumstances indicate that the carrying value of the asset may not be recoverable. No such triggering events were identified during the period from the date of acquisition to March 31, 2019 and therefore no impairment loss was recognized for the three months ended March 31, 2019. In April 2018, we entered into an agreement with Impax Laboratories, Inc. (now Amneal) to purchase the approved ANDAs for three previously-commercialized generic drug products, the approved ANDAs for two generic drug products that have not yet been commercialized, the development package for one generic drug product, a license, supply, and distribution agreement for a generic drug product with an ANDA that is pending approval, and certain manufacturing equipment required to manufacture one of the products, for $2.3 million in cash (Note 9). At the same time, we entered into a supply agreement with Amneal under which we may elect to purchase the finished goods for one of the products for up to 17 months beginning October 1, 2019, under certain conditions. If we do elect to purchase the finished goods from Amneal for this period, we may be required to pay a milestone payment of up to $10.0 million upon launch, depending on the number of competitors selling the product at the time of launch. This milestone payment was determined to be contingent consideration and will be recognized when the contingency is resolved. In April 2018, we entered into an agreement with IDT Australia, Limited to purchase the ANDAs for 23 previously-marketed generic drug products and API for four of the acquired products for $2.7 million in cash and a single-digit royalty on net profits from sales of one of the products (Note 9). We made the $2.7 million cash payment using cash on hand and capitalized $18 thousand of costs directly related to the asset purchase. We accounted for this transaction as an asset purchase. The $2.5 million acquired ANDA intangible assets were recorded at their relative fair value, determined using Level 3 unobservable inputs. In order to determine the fair value of the product rights intangible assets, we used the present value of the estimated cash flows related to the product rights, using discount rates of 10% to 15%. The acquired ANDA intangible assets will be amortized in full over their 10-year useful lives, and will be tested for impairment when events or circumstances indicate that the carrying value of the asset may not be recoverable. No such triggering events were identified during the period from the date of acquisition to March 31, 2019 and therefore no impairment loss was recognized for the three months ended March 31, 2019. We also recorded $0.2 million of raw materials inventory, measured at fair value. The fair value of the raw materials inventory was determined based on the estimated replacement cost.

BUSINESS, PRESENTATION, AND R_2

BUSINESS, PRESENTATION, AND RECENT ACCOUNTING PRONOUNCEMENTS (Policies)	3 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In our opinion, the accompanying unaudited interim condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly our financial position, results of operations, comprehensive (loss)/income, and cash flows. The consolidated balance sheet at December 31, 2018, has been derived from audited financial statements of that date. The unaudited interim condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the United States Securities and Exchange Commission. We believe that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited financial statements and notes previously distributed in our Annual Report on Form 10-K for the year ended December 31, 2018.
Principles of consolidation	Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of ANI Pharmaceuticals, Inc. and its subsidiaries. All intercompany accounts and transactions are eliminated in consolidation.
Foreign Currency	Foreign Currency The Company has a subsidiary located in Canada. The subsidiary conducts its transactions in U.S. dollars and Canadian dollars, but its functional currency is the U.S. dollar. The results of any non-U.S. dollar transactions are remeasured in U.S. dollars at the applicable exchange rates during the period and resulting foreign currency transaction gains and losses are included in the determination of net income. Our loss on transactions determined in foreign currencies was immaterial for the quarter ended March 31, 2019. Unless otherwise noted, all references to “$” or “dollar” refer to the U.S. dollar.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. In the accompanying consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, revenue recognition, allowance for doubtful accounts, variable consideration determined based on accruals for chargebacks, administrative fees and rebates, government rebates, returns and other allowances, allowance for inventory obsolescence, valuation of financial instruments and intangible assets, accruals for contingent liabilities, fair value of long-lived assets, income tax provision, deferred taxes and valuation allowance, determination of right-of-use assets and lease liabilities, purchase price allocations, and the depreciable lives of long-lived assets. Because of the uncertainties inherent in such estimates, actual results may differ from those estimates. Management periodically evaluates estimates used in the preparation of the financial statements for reasonableness.
Leases	Leases At the inception of a contract we determine if the arrangement is, or contains, a lease. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Rent expense is recognized on a straight-line basis over the lease term. We have made certain accounting policy elections whereby we (i) do not recognize ROU assets or lease liabilities for short-term leases (those with original terms of 12-months or less) and (ii) combine lease and non-lease elements of our operating leases. Operating lease ROU assets are included in other non-current assets and operating lease liabilities are included in accrued expenses and other and other non-current liabilities in our consolidated balance sheets. As of March 31, 2019, we did not have any finance leases.
Geographic Information	Based on the distinct nature of our operations, our internal management structure, and the financial information that is evaluated regularly by our Chief Operating Decision Maker, we determined that we operate in one reportable segment. Our operations are located in the United States and Canada. The following table depicts the Company’s revenue by geographic operations during the following periods: (in thousands) Three Months Ended Location of Operations March 31, 2019 March 31, 2018 United States $ 50,900 $ 46,483 Canada 1,987 - Total Revenue $ 52,887 $ 46,483 The following table depicts the Company’s property and equipment, net according to geographic location as of: (in thousands) March 31, 2019 December 31, 2018 United States 24,727 $ 24,437 Canada 13,698 13,653 Total property and equipment, net $ 38,425 $ 38,090
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recent Accounting Pronouncements Not Yet Adopted In November 2018, the Financial Accounting Standards Board (“FASB”) issued guidance clarifying that certain transactions between collaborative arrangement participants should be accounted for revenue under Accounting Standards Codification Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. The guidance is effective for reporting periods beginning after December 15, 2019, including interim periods within that fiscal year. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the impact, if any, that the adoption of this guidance will have on our consolidated financial statements. In August 2018, the FASB issued guidance modifying the disclosure requirements on fair value measurements. The amendments add, modify, and eliminate certain disclosure requirements on fair value measurements. The guidance is effective for reporting periods beginning after December 15, 2019, including interim periods within that fiscal year. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the impact, if any, that the adoption of this guidance will have on our consolidated financial statements. In June 2016, the FASB issued guidance with respect to measuring credit losses on financial instruments, including trade receivables. The guidance eliminates the probable initial recognition threshold that was previously required prior to recognizing a credit loss on financial instruments. The credit loss estimate can now reflect an entity's current estimate of all future expected credit losses. Under the previous guidance, an entity only considered past events and current conditions. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption of certain amendments of this guidance must be applied on a modified retrospective basis and the adoption of the remaining amendments must be applied on a prospective basis. We currently expect that the adoption of this guidance will likely change the way we assess the collectability of our receivables and recoverability of other financial instruments. We have not yet begun to evaluate the specific impacts of this guidance. We have evaluated all other issued and unadopted Accounting Standards Updates and believe the adoption of these standards will not have a material impact on our condensed consolidated statements of operations, comprehensive (loss)/income, balance sheets, or cash flows. Recently Adopted Accounting Pronouncements In October 2018, the FASB issued guidance for accounting for derivatives and hedging. The guidance provides for the inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index swap rate as a benchmark interest rate for hedge accounting purposes. In July 2017, the Financial Conduct Authority in the United Kingdom announced that it would phase out London Interbank Offered Rate (“LIBOR”) as a benchmark by the end of 2021. As a result, the U.S. Federal Reserve identified the SOFR as its preferred alternative reference rate, calculated with a broad set of short-term repurchase agreements backed by treasury securities. Amounts drawn under our five-year senior secured credit facility bear interest rates in relation to LIBOR, and our interest rate swap is designated in LIBOR. The guidance was effective for reporting periods beginning after December 15, 2018 and early adoption was permitted. We adopted this guidance as of January 1, 2019 on a prospective basis. The adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2018, the Securities and Exchange Commission (“SEC”) adopted the final rule amending certain disclosure requirements that have become redundant, duplicative, overlapping, outdated, or superseded. In addition, the amendments expand the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The rule was effective on November 5, 2018 and was effective for the quarter that began after the effective date. The adoption of this guidance resulted in the inclusion of the statement of changes stockholder’s equity in our interim financial statement filings. In June 2018, the FASB issued guidance simplifying the accounting for nonemployee stock-based compensation awards. The guidance aligns the measurement and classification for employee stock-based compensation awards to nonemployee stock-based compensation awards. Under the guidance, nonemployee awards will be measured at their grant date fair value. Upon transition, the existing nonemployee awards will be measured at fair value as of the adoption date. The guidance was effective for reporting periods beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption was permitted, including adoption in an interim period. We adopted this guidance as of January 1, 2019. The adoption of this guidance did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued guidance for accounting for leases. The guidance requires lessees to recognize assets and liabilities related to long-term leases on the balance sheet and expands disclosure requirements regarding leasing arrangements. In July 2018, the FASB issued additional guidance, which offers a transition option to entities adopting the new lease standards. Under the transition option, entities can elect to apply the new guidance using a modified retrospective approach at the beginning of the year in which the new lease standard is adopted, rather than to the earliest comparative period presented in their financial statements. The guidance was effective for reporting periods beginning after December 15, 2018 and early adoption was permitted. The guidance was adopted on a modified retrospective basis and provides for certain practical expedients. We adopted this guidance effective January 1, 2019 using the following practical expedients:  we did not reassess if any expired or existing contracts are or contain leases;  we did not reassess the classification of any expired or existing leases. Additionally, we made ongoing accounting policy elections whereby we (i) do not recognize right-of-use assets or lease liabilities for short-term leases (those with original terms of 12 -months or less) and (ii) combine lease and non-lease elements of our operating leases. Upon adoption of the new guidance on January 1, 2019, we recognized a right-of-use asset of approximately $0.5 million, which was reduced by approximately $10 thousand of net prepaid rents at the date of adoption, along with a lease liability of approximately $0.5 million. We also recognized total deferred tax assets of approximately $0.1 million and deferred tax liabilities of approximately $0.1 million related to book-tax basis differences. The net effect of the adoption resulted in a cumulative effect adjustment to retained earnings on January 1, 2019 of approximately $2 thousand.
