BioDelivery Sciences International, Inc. and subsidiaries (the “Company”) was incorporated in the State of Indiana on January 6, 1997 and reincorporated as a Delaware corporation in 2002. The Company’s subsidiaries are Arius Pharmaceuticals, Inc., a Delaware corporation (“Arius One”) and Arius Two, Inc., a Delaware corporation (“Arius Two”), each of which are wholly-owned.

The Company is a rapidly growing specialty pharmaceutical company dedicated to patients living with chronic pain and associated conditions. The Company has built a portfolio of products that includes utilizing its novel and proprietary BioErodible MucoAdhesive, or BEMA, drug-delivery technology to develop and commercialize new applications of proven therapies aimed at addressing important unmet medical needs. The Company commercializes in the U.S. using its own sales force while working in partnership with third parties to commercialize its products outside the U.S.

The preparation of the accompanying consolidated financial statements requires management 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 consolidated financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. The Company reviews all significant estimates affecting the consolidated financial statements on a recurring basis and records the effect of any necessary adjustments prior to their issuance. Significant estimates made by the Company include: revenue recognition associated with sales allowances such as returns of product sold, government program rebates, customer coupon redemptions, wholesaler/pharmacy discounts, product service fees, rebates and chargebacks; sales bonuses; stock-based compensation; determination of fair values of assets and liabilities relating to business combinations; and deferred income taxes.

The Company relies on certain materials used in its development and third-party manufacturing processes, most of which are procured from three contract manufacturers and four active pharmaceutical ingredient (“API”) suppliers for BELBUCA, Symproic and BUNAVAIL^®. The Company purchases its pharmaceutical ingredients pursuant to long-term supply agreements with a limited number of suppliers. The failure of a supplier, including a subcontractor, to deliver on schedule could delay or interrupt the development or commercialization process and thereby adversely affect the Company’s operating results. In addition, a disruption in the commercial supply of or a significant increase in the cost of the API from any of these sources could have a material adverse effect on the Company’s BELBUCA and Symproic business, which would affect the Company’s financial position and results of operations.

In 2019, the Company utilized only one contract manufacturer to create the BELBUCA and BUNAVAIL laminates and a second contract manufacturer to package the laminates into final product. The Company utilizes only one contract manufacturer to create the Symproic tablets and only one contract manufacturer to package the tablets into final product. Although the Company has long term supply agreements with these two vendors, any problems or regulatory issues at either of these vendors could create significant BELBUCA and Symproic supply delays. Amounts due to these vendors represented approximately 30.3% and 6.3% of total accounts payable as of December 31, 2019 and 2018, respectively.

In 2019, the Company sold its BELBUCA, Symproic and BUNAVAIL products primarily to large national wholesalers, which in turn may resell the products to smaller or regional wholesalers, retail pharmacies, chain drug stores, government agencies and other third parties. The following table lists the Company’s customers that individually comprise greater than 10% of total accounts receivable:

The Company places cash on deposit with financial institutions in the United States. The Federal Deposit Insurance Corporation covers $0.25 million for substantially all depository accounts. As of December 31, 2019, the Company had approximately $65.1 million, which exceeded these insured limits. As of December 31, 2018, the Company had approximately $43.6 million, which exceeded these insured limits.

The Company offers wholesale distributors a prompt payment discount if they make payments within a prescribed number of days. This discount is generally 2% but may be higher in some instances due to product launches or customer and/or industry expectations. Because the Company’s wholesale distributors typically take the prompt payment discount, the Company accrues 100% of the prompt payment discounts, based on the gross amount of each invoice, at the time of sale, and the Company applies earned discounts at the time of payment. The allowance for prompt payment discounts was $0.9 million and $0.3 million as of December 31, 2019 and 2018, respectively.

The Company performs ongoing credit evaluations and does not require collateral. As appropriate, the Company establishes provisions for potential credit losses. There were no allowances for doubtful accounts as of December 31, 2019 or 2018. The Company writes off accounts receivable when management determines they are uncollectible and credits payments subsequently received on such receivables to bad debt expense in the period received.

Inventories are stated at the lower of cost or net realizable value with costs determined for each batch under the first-in, first-out method and specifically allocated to remaining inventory. Inventory consists of raw materials, work in process and finished goods. Raw materials include amounts of active pharmaceutical ingredient for a product to be manufactured, work in process includes the bulk inventory of laminate (the Company’s drug delivery film) prior to being packaged for sale, and finished goods include pharmaceutical products ready for commercial sale.

On a quarterly basis, the Company analyzes its inventory levels and records allowances for inventory that has become obsolete, inventory that has a cost basis more than the expected net realizable value and inventory that is more than expected demand based upon projected product sales. The Company recorded $0.4 million and $0.2 million in reserves for inventory obsolescence as of December 31, 2019 and 2018, respectively. The 2019 reserve includes an additional $0.2 million associated with the announced discontinuation of marketing of BUNAVAIL.

The Company evaluates the carrying value of equipment when events or changes in circumstances indicate the related carrying amount may not be recoverable. In connection with the discontinuation of the marketing of BUNAVAIL, the company recorded an additional $1.5 million of depreciation related to certain equipment used in the production of BUNAVAIL. The Company has certain manufacturing equipment that isn’t currently in production, which has been deemed idle. There was no impairment of equipment recorded during the year ended December 31, 2019 or 2018.

The Company reviews intangible assets with finite lives (“other intangible assets”) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company uses an estimate of the undiscounted cash flows over the remaining life of its other intangible assets, or related group of assets where applicable, in measuring whether the assets to be held and used will be realizable. In the event of impairment, the Company would discount the future cash flows using its then estimated incremental borrowing rate to estimate the amount of the impairment.

Goodwill is evaluated for impairment at least annually or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable. During the evaluation of the potential impairment of goodwill, either a qualitative or a quantitative assessment may be performed. If a qualitative evaluation determines that it is more likely than not that no impairment exists, then no further analysis is performed. If a qualitative evaluation is unable to determine whether it is more likely than not that impairment has occurred, a quantitative evaluation is performed. If the carrying value exceeds the fair value, an impairment charge is recorded based on that difference. There were no goodwill impairment charges in 2019, 2018 or 2017.

The Company recognizes revenue on product sales when control of the promised goods is transferred to its customers in an amount that reflects the consideration expected to be received in exchange for transferring those goods. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. When determining whether the customer has obtained control of the goods, the Company considers any future performance obligations. Generally, there is no post-shipment obligation on product sold.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company’s product sales contracts have a single performance obligation as the promise to transfer the individual goods is not separately identifiable from other promises in the contracts and, therefore, not distinct. The Company’s performance obligations are satisfied at a point in time. The multiple performance obligations are not allocated based off of the obligations but based off of standard selling price.

The Company recognizes product sales net of estimated allowances for rebates, price adjustments, returns, chargebacks, vouchers and prompt payment discounts. A significant majority of the Company’s adjustments to gross product revenues are the result of accruals for its commercial contracts, retail consumer subsidy programs, and Medicaid and Medicare rebates.

In its analyses, The Company uses prescription data purchased from a third-party data provider to develop estimates of historical inventory channel sell-through. The Company utilizes an internal analysis to compare historical net product shipments to estimated historical prescriptions written. Based on that analysis, management develops an estimate of the quantity of product in the channel which may be subject to various rebate, chargeback and product return exposures. To estimate months of ending inventory in the Company’s distribution channel, the Company divides estimated ending inventory in the distribution channel by the Company’s recent prescription data, not considering any future anticipated demand growth beyond the succeeding quarter. Monthly for each product line, the Company prepares an internal estimate of ending inventory units in the distribution channel by adding estimated inventory in the channel at the beginning of the period, plus net product shipments for the period, less estimated prescriptions written for the period. This is done for each product line by applying a rate of historical activity for rebates, chargebacks and product returns, adjusted for relevant quantitative and qualitative factors discussed above, to the potential exposed product estimated to be in the distribution channel. In addition, the Company receives daily information from the wholesalers regarding their sales and actual on hand inventory levels of the Company’s products. This enables the Company to execute accurate provisioning procedures.

Price adjustments and chargebacks-The Company’s estimates of price adjustments and chargebacks are based on its estimated mix of sales to various third-party payers, which are entitled either contractually or statutorily to discounts from the Company’s listed prices of its products. If the sales mix to third-party payers is different from the Company’s estimates, the Company may be required to pay higher or lower total price adjustments and/or chargebacks than it had estimated, and such differences may be significant.

The Company, from time to time, offers certain promotional product-related incentives to its customers. During 2019, the Company had voucher programs for BELBUCA Symproic and BUNAVAIL whereby the Company offers a point-of-sale subsidy to retail consumers. The Company estimates its liabilities for these voucher programs based on the current utilization and historical redemption rates as reported to the Company by a third-party claims processing organization. The Company accounts for the costs of these special promotional programs as price adjustments, which are a reduction of gross revenue.

Gross to net accruals-A significant majority of the Company’s gross to net adjustments to gross product revenues are the result of accruals for its voucher program and rebates related to Medicare Part D, Part D Coverage Gap, Medicaid and commercial contracts, with most of those programs having an accrual to payment cycle of anywhere from one to three months. In addition to this relatively short accrual to payment cycle, the Company receives daily information from the wholesalers regarding their sales of the Company’s products and actual on hand inventory levels of its products. This enables the Company to execute accurate provisioning procedures. Consistent with the pharmaceutical industry, the accrual to payment cycle for returns is longer and can take several years depending on the expiration of the related products.

The Company periodically enters into license and development agreements to develop and commercialize its products. The arrangements typically are multi-deliverable arrangements that are funded through upfront payments, milestone payments and other forms of payment. The Company currently has license agreements that are described in note 7, of which these revenues are classified as contract revenue.

In 2019, cost of sales included the direct costs attributable to the production of BELBUCA, Symproic and BUNAVAIL. It included raw materials, production costs at the Company’s three contract manufacturing sites, quality testing directly related to the products, inventory adjustment charges, and depreciation on equipment that the Company had purchased to produce BELBUCA and BUNAVAIL. It also includes any batches not meeting specifications and raw material yield losses. Yield losses and batches not meeting specifications are expensed as incurred. Cost of sales is recognized when sold to the wholesaler from our distribution center.

For BREAKYL and PAINKYL (the Company’s out-licensed breakthrough cancer pain therapies), cost of sales includes all costs related to creating the product at the Company’s contract manufacturing location in Germany. The Company’s contract manufacturer bills the Company for the final product, which includes materials, direct labor costs, and certain overhead costs as outlined in applicable supply agreements.

Research and development expenses have historically consisted of product development expenses incurred in identifying, developing and testing product candidates. Product development expenses consisted primarily of labor, benefits and related employee expenses for personnel directly involved in product development activities; fees paid to professional service providers for monitoring and analyzing clinical trials; regulatory costs; costs of contract research and manufacturing of inventory used in testing and clinical trials.

As of January 1, 2019, the Company has focused entirely on commercialized products rather than research and development. As such, there were no expenses incurred in research and development during the year ended December 31, 2019. Research and development expense for the years ended December 31, 2018 and 2017 totaled $4.9 million and $13.0 million, respectively.

Advertising costs, which include promotional expenses and the cost of placebo samples, are expensed as incurred. Advertising expenses were $10.8 million, $4.5 million and $3.8 million for the years ended December 31, 2019, 2018 and 2017, respectively, and are included in selling, general and administrative expenses in the accompanying consolidated statements of operations.

Shipping and handling costs, which include expenses from our wholesalers, are expensed as incurred. Shipping and handling costs were $0.03 million, $0.02 million and $0.01 million for the years ended December 31, 2019, 2018 and 2017, respectively, and are included in selling, general and administrative expenses in the accompanying consolidated statements of operations.

The Company has a stock-based compensation plan under which various types of equity-based awards are granted, including stock options, restricted stock units (RSUs) and performance-based RSUs. The fair value of stock option and RSUs, which are subject only to service conditions with graded vesting, are recognized as compensation expense, generally on a straight-line basis over the service period, net of estimated forfeitures. Forfeitures are recognized as they occur. The fair values of performance-based RSUs are recognized as compensation expense from the grant date to the end of the performance period. The Company uses the fair-value based method to determine compensation for all arrangements under which employees and others receive shares of stock or equity instruments (warrants and options). The grant date fair value of an RSU equals the closing price of our common stock on the trading day preceding the grant date. The fair value of each option and warrant is estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate. Expected volatility is based on historical volatility of the Company’s Common Stock and other factors estimated over the expected term of the options. The expected term of options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus the contract term. The risk-free rate is based on the U.S. Treasury yield.

GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. GAAP also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company considers the carrying amount of its cash and cash equivalents to approximate fair value due to short-term nature of this instrument. GAAP describes three levels of inputs that may be used to measure fair value:

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The authoritative guidance significantly amends the current accounting for leases. Under the new provisions, all lessees will report a right-of-use asset and a liability for the obligation to make payments for all leases with the exception of those leases with a term of 12 months or less. All other leases will fall into one of two categories: (i) a financing lease or (ii) an operating lease. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842 (Leases), which amends narrow aspects of the guidance issued in the amendments in ASU 2016-02, and ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which allows entities to recognize a cumulative-effect adjustment from the application of ASU 2016-02 to the opening balance of retained earnings in the period of adoption. Effective January 1, 2019, the Company adopted Topic 842 using the modified retrospective method as of January 1, 2019 and will not restate comparative periods. The Company elected the optional package of practical expedients, which allowed the Company to not reassess: (i) whether any expired or existing contracts are considered or contain leases; (ii) lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. The new standard also allows entities to make certain policy elections, including a policy to not separate lease and non-lease components, which the Company did not elect for its facility and office equipment lease. Refer to footnote three “Leases” for further information.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments; in November 2018 the FASB issued a subsequent amendment ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses; in April 2019 the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses. In May 2019 the FASB issued ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief; and in November 2019 the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses. The new guidance changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. In November 2019 the FASB issued ASU No. 2019-10, Financial Instruments—Credit Losses (Topic 326). This guidance is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. The Company is currently evaluating the timing and effect the new guidance will have on its consolidated financial statements.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606, which amends ASC 808 to clarify ASC 606 should apply in entirety to certain transactions between collaborative arrangement participants. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently evaluating but does not expect the new guidance to have a material impact on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740)—Simplifying the Accounting for Income Taxes, which is intended to simplify accounting for income taxes. It removes certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020 and early adoption is permitted. The Company is currently evaluating but does not expect the new guidance to have a material impact on its consolidated financial statements.
