1.	Organization, basis of presentation and summary of significant policies:

Overview

BioDelivery Sciences International Inc., together with its subsidiaries (collectively, the “Company” or “BDSI”) is a specialty pharmaceutical company that is leveraging its novel and proprietary patented drug delivery technologies to develop and commercialize, either on its own or in partnerships with third parties, new applications of proven therapeutics. The Company is focusing on developing products to meet unmet patient needs in the areas of pain management and addiction.

The accompanying unaudited consolidated financial statements include all adjustments (consisting of normal and recurring adjustments) necessary for a fair presentation of these financial statements. The consolidated balance sheet at December 31, 2014 has been derived from the Company’s audited consolidated financial statements included in its annual report on Form 10-K for the year ended December 31, 2014. Certain footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted pursuant to the Securities and Exchange Commission (“SEC”) rules and regulations. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2014.

Operating results for the three month period ended March 31, 2015 are not necessarily indicative of results for the full year or any other future periods.

As used herein, the Company’s common stock, par value $.001 per share, is referred to as the “Common Stock”.

Use of estimates in financial statements

The preparation of the accompanying condensed consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions.

Inventory

Inventories are stated at the lower of cost or market value with costs determined on the first-in, first-out method. Inventory consists of raw materials, work in process and finished goods. Raw materials include active pharmaceutical ingredient (“API”) for a product to be manufactured, work in process includes the bulk inventory of laminate 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 in excess of the expected net realizable value and inventory that is in excess of expected demand based upon projected product sales. There were no allowances recorded at March 31, 2015.

Deferred revenue

Consistent with the Company’s revenue recognition policy, deferred revenue represents cash received in advance for licensing fees, consulting, research and development services, related supply agreements and product sales. Such payments are reflected as deferred revenue until recognized under the Company’s revenue recognition policy. Deferred revenue is classified as current if management believes the Company will be able to recognize the deferred amount as revenue within twelve months of the balance sheet date.

Revenue recognition

Product Sales- The Company recognizes revenue from its product sales upon transfer of title, which occurs when product is received by its customers. The Company sells its products primarily to large national wholesalers, which have the right to return the products they purchase. The Company is required to reasonably estimate the amount of future returns at the time of revenue recognition. The Company recognizes product sales net of estimated allowances for rebates, price adjustments, chargebacks, prompt payment and other discounts. When the Company cannot reasonably estimate the amount of future product returns, it defers revenues until the risk of product return has been substantially eliminated.

As of March 31, 2015 and December 31, 2014, the Company had $1.0 million and $0.8 million of deferred revenue related to sales to wholesalers for which future returns could not be reasonably estimated at the time of sale. Deferred revenue is recognized when the product is sold to the end user, based upon prescriptions filled. To estimate product sold to end users, the Company relies on third-party information, including prescription data and information obtained from significant distributors with respect to their inventory levels and sales to customers. Deferred revenue is recorded net of estimated allowances for rebates, price adjustments, chargebacks, prompt payment and other discounts. Estimated allowances are recorded and classified as accrued liabilities in the accompanying balance sheets as of March 31, 2015 and December 31, 2014 (Note 4).

Product Returns- Consistent with industry practice, the Company offers contractual return rights that allow its customers to return the products within an 18-month period that begins six months prior to and ends twelve months subsequent to expiration of the products. The Company does not believe it has sufficient experience with BUNAVAIL^® to estimate its returns at time of exfactory sales. When the Company cannot reasonably estimate the amount of future product returns, it records revenues when the risk of product return has been substantially eliminated which is at the time the product is sold to the end user.

Rebates- The liability for government program rebates is calculated based on historical and current rebate redemption and utilization rates contractually submitted by each program’s administrator.

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. In the event that 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. These programs include certain product incentives to pharmacy customers and other sales stocking allowances. The Company has voucher programs for 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 historical redemption rates for similar completed programs used by other pharmaceutical companies as reported to the Company by a third-party claims processing organization and actual redemption rates for the Company’s completed programs. The Company accounts for the costs of these special promotional programs as price adjustments, which are a reduction of gross revenue.

Prompt Payment Discounts- The Company typically offers its wholesale customers a prompt payment discount of 2% as an incentive to remit payments within the first 30 to 37 days after the invoice date depending on the customer and the products purchased.

Deferred Cost of Sales

The Company defers its cost of sales in connection with BUNAVAIL^® sales at time of ex-factory sales. These costs are recognized when the product is sold to the end user. The Company had $0.9 million and $0.7 million of deferred costs of sales at March 31, 2015 and December 31, 2014, respectively, which are included in other current assets in the accompanying condensed consolidated balance sheets.

Cost of Sales

The cost of sales attributable to the production of BUNAVAIL^® includes raw materials, production costs at our two contract manufacturing sites, quality testing directly related to the product, and depreciation on equipment that we have purchased to produce BUNAVAIL^®. It also includes any batches not meeting specifications and raw material yield loss. Yield losses and batches not meeting specifications are expensed as incurred. Cost of sales is recognized as actual product is sold through to the end user. During the three months ended March 31, 2015, the Company wrote down $0.2 million of inventory to lower of cost or market, which is recorded as cost of sales in the accompanying condensed consolidated statement of operations.

The cost of sales attributable to the production of ONSOLIS^® and BREAKYL™ includes all costs related to creating the product at the Company’s contract manufacturing locations in the U.S. and Germany. The Company’s contract manufacturers bill the Company for the final product, which includes materials, direct labor costs, and certain overhead costs as outlined in applicable supply agreements. Cost of sales also includes royalty expenses that the Company owes to third parties.

Recent accounting pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements of Accounting Standards Codification (“ASC”) Topic 605, “Revenue Recognition” and most industry-specific guidance on revenue recognition throughout the ASC. The new standard is principles-based and provides a five step model to determine when and how revenue is recognized. The core principle of the new standard is that revenue should be recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. The new standard also requires disclosure of qualitative and quantitative information surrounding the amount, nature, timing and uncertainty of revenues and cash flows arising from contracts with customers. The new standard will be effective for the Company in the first quarter of the year ending December 31, 2017 and can be applied either retrospectively to all periods presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption is not permitted. The Company is currently evaluating the impact of adoption of the new standard on its consolidated financial statements.
