Accounting Policies [Abstract] |
Use of Estimates | (a) Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include those related to stock-based compensation; income tax uncertainties; the fair value of the warrant liability and the useful lives of property and equipment.
Cash and Cash Equivalents | (b) Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities to the Company of three months or less to be cash equivalents. Although the Company may deposit its cash and cash equivalents with multiple financial institutions, its deposits, at times, may exceed federally insured limits. Cash and cash equivalents were $3.0 million and $19.2million at December 31, 2021 and 2020.
Receivables | (c) Receivables Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts for estimated losses. In establishing the allowance, management considers historical losses adjusted to take into account current market conditions and their customers’ financial condition, the amount of receivables in dispute, and the current receivables aging and current payment patterns. The Company had no write-offs in 2021 and 2020 and the Company did not record an allowance for doubtful accounts as of December 31, 2021 and 2020 as there were no accounts receivable outstanding. The Company does not have any off-balance-sheet credit exposure related to its customers.
Revenue Recognition | (d) Revenue Recognition The Company generates most of its revenue from license and royalty arrangements. At inception of each contract, the Company identifies the goods and services that have been promised to the customer and each of those that represent a distinct performance obligation, determines the transaction price including any variable consideration, allocates the transaction price to the distinct performance obligations and determines whether control transfers to the customer at a point in time or over time. Variable consideration is included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company reassess its reserves for variable consideration at each reporting date and makes adjustments, if necessary, which may affect revenue and earnings in periods in which any such changes become known. LIPOCINE INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2021 and 2020 (2) Summary of Significant Accounting Policies – (continued) Disaggregation of Revenue. In the following tables, revenues reported for the year ended December 31, 2021, under Topic 606, is disaggregated by type of revenue. Schedule of Disaggregation of Revenue
Type of Revenue |  |
Licensing |  | $ | 11,000,000 |
Sales-based royalties |  |  | 54,994 |
Minimum guaranteed royalties |  |  | 4,050,000 |
Materials |  |  | 1,035,844 |
Revenue |  | $ | 16,140,838 |
Under Topic 606, all revenue has been recognized as point in time for the year ended December 31, 2021. See Note 4 for a description of the license agreement with Antares Pharma, Inc. See Note 12 for a description of the agreement with Spriaso. License Fees. For distinct license performance obligations, upfront license fees are recognized when the Company satisfies the underlying performance obligation. This generally occurs upon transfer of the right to use the Company’s licensed technology to the customer. In addition, license arrangements may include contingent milestone payments, which are due following achievement by our licensee of specified sales or regulatory milestones and the licensee and/or Company will fulfill its performance obligation prior to achievement of these milestones. Because of the uncertainty of the milestone achievement, and/or the dependence on sales of our licensee, variable consideration for contingent milestones is fully constrained and is not recognized as revenue until the milestone is achieved by our licensee, to the extent collectability is reasonably certain. Royalties. Royalties revenue consists of sales-based and minimum royalties earned under licenses agreements for our products. Performance obligations under these licenses, which consist of the right to use the Company’s proprietary technology, are satisfied at a point in time corresponding with delivery of the underlying technology rights to the licensee, which is generally upon transfer of the licensed technology/product to the customer. Sales-based royalties revenue represents variable consideration under the license agreements and is recognized in the period a customer sells products incorporating the Company’s licensed technologies/products. The Company estimates sales-based royalties revenue earned but unpaid at each reporting period using information provided by the licensee. The Company’s license arrangements may also provide for minimum royalties, which the Company recognizes upon the satisfaction of the underlying performance obligation, which generally occurs with delivery of the underlying technology rights to the licensee.Sales-based and minimum royalties are generally due within 45 days after the end of each quarter in which they are earned. Contract Assets Contract assets consist of minimum royalty revenue earned in relation to the license agreement but not yet payable based on the terms of the contract. The contract asset as of December 31, 2021 is related to the Antares License Agreement. Revenue Concentration A major customer is considered to be one that comprises more than 10% of the Company’s total revenues. There was one major customer for the year ended December 31, 2021 which accounted for 99.7% of total revenue. There was no revenue recognized for the year ended December 31, 2020. LIPOCINE INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2021 and 2020
(2) | Summary of Significant Accounting Policies – (continued)
Property and Equipment | (e) Property and Equipment Property and equipment are recorded at cost, less accumulated depreciation. Maintenance and repairs that do not extend the life or improve the asset are expensed in the year incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which are five years for laboratory and office equipment, three years for computer equipment and software, and seven years for furniture and fixtures.
Accounting for Impairment of Long-Lived Assets | (f) Accounting for Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset to future net cash flows (undiscounted) expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets held for sale are reported at the lower of the carrying amount, or fair value, less costs to sell.
Income Taxes | (g) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the net deferred tax assets will not be realized. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50 percent likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits as a component of its income tax expense.
Share Based Payments | (h) Share Based Payments The Company recognizes stock-based compensation expense for grants of stock option awards, restricted stock units and restricted stock under the Company’s Incentive Plan to employees, nonemployees and nonemployee members of the Company’s board of directors based on the grant-date fair value of those awards. The grant-date fair value of an award is generally recognized as compensation expense over the award’s requisite service period. In addition, the Company has granted performance-based stock option awards and restricted stock units, which vest based upon the Company satisfying certain performance conditions. Potential compensation cost, measured on the grant date, related to these performance options will be recognized only if, and when, the Company estimates that these options or units will vest, which is based on whether the Company considers the performance conditions to be probable of attainment. The Company’s estimates of the number of performance-based options or units that will vest will be revised, if necessary, in subsequent periods. LIPOCINE INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2021 and 2020
(2) | Summary of Significant Accounting Policies – (continued)
The Company uses the Black-Scholes model to compute the estimated fair value of stock option awards. Using this model, fair value is calculated based on assumptions with respect to (i) expected volatility of the Company’s Common Stock price, (ii) the periods of time over which employees, nonemployees and members of the board of directors are expected to hold their options prior to exercise (expected term), (iii) expected dividend yield on the Common Stock, and (iv) risk-free interest rates. Stock-based compensation expense also includes an estimate, which is made at the time of grant, of the number of awards that are expected to be forfeited. This estimate is revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation cost that has been expensed in the statements of operations amounted to $604,000 and $1.4 million for the years ended December 31, 2021 and 2020, allocated as follows: Schedule of Employee Service Share-based Compensation, Allocation of Recognized Period Costs
|  | Year Ended |
|  | 2021 |  |  | 2020 |
Research and development |  | $ | 280,186 |  |  | $ | 583,212 |
General and administrative |  |  | 323,760 |  |  |  | 789,970 |
|  | $ | 603,946 |  |  | $ | 1,373,182 |
The Company issued 1,106,000 stock options and 1,360,000 stock options during the years ended December 31, 2021 and 2020, respectively. Key assumptions used in the determination of the fair value of stock options granted are as follows: Expected Term: The expected term represents the period that the stock-based awards are expected to be outstanding. Due to limited historical experience of similar awards, the expected term was estimated using the simplified method in accordance with the provisions of Staff Accounting Bulletin (“SAB”) No. 107, Share-Based Payment, for awards with stated or implied service periods. The simplified method defines the expected term as the average of the contractual term and the vesting period of the stock option. For awards with performance conditions, and that have the contractual term to satisfy the performance condition, the contractual term was used. Risk-Free Interest Rate: The risk-free interest rate used was based on the implied yield currently available on U.S. Treasury issues with an equivalent remaining term. Expected Dividend: The expected dividend assumption is based on management’s current expectation about the Company’s anticipated dividend policy. The Company does not anticipate declaring dividends in the foreseeable future. Expected Volatility: The volatility factor is based solely on the Company’s trading history. LIPOCINE INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2021 and 2020
(2) | Summary of Significant Accounting Policies – (continued)
For options granted in 2021 and 2020, the Company calculated the fair value of each option grant on the respective dates of grant using the following weighted average assumptions: Schedule of Key Assumption of Fair Value of Stock Options Granted
|  | 2021 |  |  | 2020 |
Expected term |  |  | 5.83 years |  |  |  | 5.83 years |
Risk-free interest rate |  |  | 1.04 | % |  |  | 0.93 | %
Expected dividend yield |  |  | — |  |  |  | — |
Expected volatility |  |  | 102.18 | % |  |  | 100.32 | %
FASB Accounting Standards Codification (“ASC”) 718, Stock Compensation, requires the Company to recognize compensation expense for the portion of options that are expected to vest. Therefore, the Company applied estimated forfeiture rates that were derived from historical employee termination behavior. If the actual number of forfeitures differs from those estimated by management, additional adjustments to compensation expense may be required in future periods. As of December 31, 2021, there was $1.4 million of total unrecognized compensation cost related to unvested share-based compensation arrangements granted under the Company’s stock option plan. That cost is expected to be recognized over a weighted average period of 2.3 years and will be adjusted for subsequent changes in estimated forfeitures. The weighted average fair value of share-based compensation awards granted during the years ended December 31, 2021 and 2020 was approximately $0.97 per share and $0.72 per share, respectively.
Fair Value | (i) Fair Value The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:
| ● | Level 1 Inputs: Quoted prices for identical instruments in active markets.
| ● | Level 2 Inputs: Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuation in which all significant inputs and significant value drivers are observable in active markets.
| ● | Level 3 Inputs: Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

(2) | Summary of Significant Accounting Policies – (continued)
All of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs. For accrued interest income, prepaid and other current assets, accounts payable, and accrued expenses, the carrying amounts approximate fair value because of the short maturity of these instruments. The following table presents the placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a recurring basis at December 31, 2021 and 2020: Schedule of Fair Value, Assets Measured on Recurring Basis

(2) | Summary of Significant Accounting Policies – (continued)
The following methods and assumptions were used to determine the fair value of each class of assets and liabilities recorded at fair value in the balance sheets: Cash equivalents: Cash equivalents primarily consist of highly rated money market funds and treasury bills with original maturities to the Company of three months or less and are purchased daily at par value with specified yield rates. Cash equivalents related to money market funds and treasury bills are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices or broker or dealer quotations for similar assets. Government bonds and notes: The Company uses a third-party pricing service to value these investments. United States bonds and notes are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices for identical assets and reportable trades. Corporate bonds, notes, and commercial paper: The Company uses a third-party pricing service to value these investments. Corporate bonds, notes and commercial paper are classified within Level 2 of the fair value hierarchy because they are valued using broker/dealer quotes, bids and offers, benchmark yields and credit spreads and other observable inputs. Warrant liability: The warrant liability (which relates to warrants to purchase shares of common stock) is marked-to-market each reporting period with the change in fair value recorded to other income (expense) in the accompanying statements of operations until the warrants are exercised, expire or other facts and circumstances lead the warrant liability to be reclassified to stockholders’ equity. The fair value of the warrant liability is estimated using a Black-Scholes option-pricing model. The significant assumptions used in preparing the option pricing model for valuing the warrant liability as of December 31, 2021, include (i) volatility of 100%, (ii) risk free interest rate of 0.97%, (iii) strike price of $0.50, (iv) fair value of common stock of $.99, and (v) expected life of 2.9 years. The significant assumptions used in preparing the option pricing model for valuing the warrant liability as of December 31, 2020, include (i) volatility of 100%, (ii) risk free interest rate of 0.27%, (iii) strike price of $0.50, (iv) fair value of common stock of $1.36, and (v) expected life of 3.9 years. The Company’s accounting policy is to recognize transfers between levels of the fair value hierarchy on the date of the event or change in circumstances that caused the transfer. There were no transfers into or out of Level 1, Level 2 or Level 3 for the years ended December 31, 2021 and 2020.
Earnings (Loss) per Share | (j) Earnings (Loss) per Share Basic earnings (loss) per share is calculated by dividing net income (loss) available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is based on the weighted average number of common shares outstanding plus, where applicable, the additional potential common shares that would have been outstanding related to dilutive options, warrants, and unvested restricted stock units to the extent such shares are dilutive.
