Note 1. General | |
We are a biopharmaceutical company that develops novel drugs. Our lead drug candidate, REMOXY® (oxycodone) Extended-Release Capsules CII, is an extended-release oral formulation of oxycodone for the management of moderate-to-severe pain when a continuous, around-the-clock opioid analgesic is needed for an extended period of time. We designed REMOXY to discourage common methods of tampering and misuse. REMOXY is being developed pursuant to the collaboration agreement and license agreement, or the Pfizer Agreements, between us and King Pharmaceuticals, Inc., a subsidiary of Pfizer, Inc., or Pfizer. | |
In the course of our development activities, we have sustained cumulative operating losses. There are no assurances that additional financing will be available on favorable terms, or at all. | |
We have prepared the accompanying unaudited condensed financial statements of Pain Therapeutics, Inc. in accordance with generally accepted accounting principles for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In our opinion, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine monthsended March 31, 2014 are not necessarily indicative of the results that may be expected for any other interim period or for the year 2014. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2013. | |
We have evaluated subsequent events through the date of filing this Form 10-Q. | |

Significant Accounting Policies | ' | |||||
Note 2. Significant Accounting Policies | ||||||
Use of Estimates | ||||||
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires that management 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 revenue earned and expenses incurred during the reporting period. Actual results could differ from those estimates. | ||||||
Revenue Recognition | ||||||
We recognize revenue when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed or determinable, and collection is reasonably assured. Program fee revenue in 2013 was derived from upfront payments under the Pfizer Agreements. Through the end of 2013, these payments were recognized from receipt over our estimate of the development period for product candidates under the Pfizer Agreements. In October 2013, we and Pfizer amended the Pfizer Agreements to focus on REMOXY and, as a result of the amendment, we recognized all then-remaining deferred program fee revenue as program fee revenue. | ||||||
Cash, Cash Equivalents and Concentration of Credit Risk | ||||||
We consider all highly liquid financial instruments with original maturities of three months or less to be cash equivalents. Cash and cash equivalents consist of cash maintained at one financial institution and in money market funds. We believe the financial risks associated with these instruments are minimal. We have not experienced material losses from our investments in these securities. | ||||||
Marketable Securities and Fair Value Measurements | ||||||
We invest in interest bearing marketable securities, generally consisting of corporate and government securities. We may elect to sell these investments before they mature. Therefore, we hold these investments as “available for sale” and include these investments in our balance sheets as current assets, even though the contractual maturity of a particular investment may be beyond one year. We report our marketable securities at fair value, which may include unrealized gains and losses. Our unrealized gains and losses on investments are recorded as a separate component of stockholders’ equity as accumulated other comprehensive income or loss. We recognize all realized gains and losses on our marketable securities on a specific identification basis in interest income in our Statements of Operations. We report changes in net unrealized gains or losses on marketable securities in our Statements of Comprehensive Income. Our marketable securities are maintained at one financial institution and are governed by our investment policy as approved by our Board of Directors. | ||||||
To date we have not recorded any impairment charges on marketable securities related to other-than-temporary declines in market value. We would recognize an impairment charge when the decline in the estimated fair value of a marketable security below the amortized cost is determined to be other-than-temporary. We consider various factors in determining whether to recognize an impairment charge, including any adverse changes in the investees’ financial condition, how long the fair value has been below the amortized cost and whether it is more likely than not that we would elect to or be required to sell the marketable security before its anticipated recovery. | ||||||
We measure our cash equivalents and marketable securities at fair value on a recurring basis. We use significant observable inputs where there are identical or comparable assets in the market to use in establishing our fair value measurements, including but not limited to benchmark yields, reported trades, broker/dealer quotes and issuer spreads. We consider these inputs to be Level 2 inputs. Generally, the types of instruments we invest in are not traded on a market such as the NASDAQ Global Market, which we would consider to be Level 1 inputs. We do not have any investments that would require inputs considered to be Level 3. We use the bid price to establish fair value where a bid price is available. | ||||||
Stock-based Compensation | ||||||
We recognize expense for the fair value of all share-based payments, including grants of employee stock options and other share based awards, in our Statements of Operations. For stock options, we use the Black-Scholes option valuation model and the single-option award approach and straight-line attribution method. Using this approach, the compensation cost is amortized on a straight-line basis over the vesting period of each respective stock option, generally four years. We estimate forfeitures and adjust this estimate periodically based on the extent to which future actual forfeitures differ, or are expected to differ, from such estimates. | ||||||
We have granted share-based awards that vest upon achievement of certain performance criteria, or Performance Awards. The value of these awards is the product of the number of shares of our common stock to be issued under the award multiplied by the fair market value of a share of our common stock on the date of grant. These awards include future performance criteria. We estimate an implicit service period for achieving these performance criteria. Performance Awards vest and common stock is issued on achieving performance criteria. We recognize stock-based compensation expense for Performance Awards when we conclude that achieving performance criteria is probable. We periodically review and update as appropriate our estimates of the implicit service periods and the likelihood of achieving the performance criteria. | ||||||
Net Loss per Share | ||||||
We compute basic net loss per share on the basis of the weighted-average number of common shares outstanding for the reporting period. We compute diluted net loss per share on the basis of the weighted-average number of common shares outstanding plus dilutive potential common shares outstanding using the treasury-stock method. Potential dilutive common shares consist of outstanding stock options and Performance Awards. | ||||||
The numerators and denominators in the calculation of basic and diluted net loss per share were as follows (in thousands except per share data): | ||||||

Weighted-average shares used in computing net loss per share, basic and diluted | 45,127 | 44,932 | ||||
Net loss per share, basic and diluted | $ | -0.08 | $ | -0.01 | ||
We excluded weighted options outstanding to purchase common stock of 4.5 million for the first quarter of 2014 and 14.4 million for the first quarter of 2013 from the calculation of diluted net loss per share because the effect of including these shares in this calculation would be anti-dilutive. | ||||||
Income Taxes | ||||||
We make estimates and judgments in determining the need for a provision for income taxes, including the estimation of our taxable income or loss for each full fiscal year. We have accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. We are uncertain about the timing and amount of any future earnings. Accordingly, we offset these deferred tax assets with a valuation allowance. We may in the future determine that certain deferred tax assets will likely be realized, in which case we will reduce our valuation allowance in the period in which such determination is made. If the valuation allowance is reduced, we may recognize a benefit from income taxes in our statement of operations in that period. We classify interest recognized pursuant to our deferred tax assets as interest expense, when appropriate. | ||||||

On December 2, 2011, a purported class action was filed against us and our executive officers in the U.S. District Court for the Western District of Texas. This complaint alleges, among other things, violations of Section 10(b), Rule 10b-5, and Section 20(a) of the Exchange Act arising out of allegedly untrue or misleading statements of material facts made by us regarding REMOXY’s development and regulatory status during the purported class period, February 3, 2011 through June 23, 2011. The complaint states that monetary damages are being sought, but no amounts are specified.

We may in the future determine that certain deferred tax assets will likely be realized, in which case we will reduce our valuation allowance in the period in which such determination is made. If the valuation allowance is reduced, we may recognize a benefit from income taxes in our statement of operations in that period. We classify interest recognized pursuant to our deferred tax assets as interest expense, when appropriate. | ||||||
