Use of Estimates and Assumptions

The preparation of financial statements in conformity with U.S. GAAP 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 unaudited condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods. The significant estimates and assumptions made in the preparation of the Company's unaudited condensed consolidated financial statements include revenue recognition, the valuation of warrants and stock-based payments, deferred income taxes, valuation of patents, accrued expenses and valuation of marketable securities.  Actual results could be materially different from those estimates, upon which the carrying values were based.

Patents

The Company owns patents that relate to various technologies.  The Company capitalizes the costs associated with acquisition, registration and maintenance of its acquired patents and amortizes these assets over their remaining useful lives on a straight-line basis.  Any further payments made to maintain or develop the patents would be capitalized and amortized over the balance of the useful life for the patents.

Revenue Recognition

The Company recognizes revenue received from the licensing of its intellectual property and other related intellectual property activities.  Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been performed pursuant to the terms of the license or other applicable agreement, (iii) amounts are fixed or determinable, and (iv) collectability of amounts is reasonably assured.  The Company relies on royalty reports received from third party licensees to record its revenue.  From time to time the Company may audit royalties reported from licensees. Any adjusted royalty revenue as a result of such audits is recorded by the Company in the period in which such adjustment is agreed to by the Company and the licensee or otherwise determined.

Income Taxes

The Company accounts for income taxes in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 740, "Income Taxes" (ASC 740), which requires the Company to use the assets and liability method of accounting for income taxes. Under the assets and liability method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between financial statement carrying amounts and the tax bases of existing assets and liabilities and operating loss and tax credit carry forward. Under this accounting standard, the effect on deferred income taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not that some portion, or all of, a deferred tax asset will not be realized.

ASC 740-10, "Accounting for Uncertainty in Income Taxes," defines uncertainty in income taxes and the evaluation of a tax position as a two-step process. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination, including the resolution of any related appeals or litigation based on the technical merits of that position. The second step is to measure a tax position that meets the more-likely-than-not threshold to determine the amount of benefit to be recognized in the financial statements. A tax position is measured at the largest amount of benefit that is greater than 50 percent likelihood of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent period in which the threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not criteria should be de-recognized in the first subsequent financial reporting period in which the threshold is no longer met.  The Company has no uncertain tax positions as of June 30, 2016 and December 31, 2015.

United States federal, state and local income tax returns prior to 2012 are not subject to examination by any applicable tax authorities.

Effective January 1, 2016, the Company has elected to early adopt Accounting Standards Update No. 2015-17, Income Taxes (Topic 740); Balance Sheet Classification of Deferred Taxes (ASU 2015-17) and classify the deferred tax assets as non-current assets on the consolidated balance sheets.  See "Accounting Standards Adopted in the Period" section of this Note B for further details.

Impairment of long-lived assets

Intangible assets with finite lives are tested for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable.  Accordingly, we record impairment losses on long-lived assets used in operations or expected to be disposed of when indicators of impairment exist and the undiscounted cash flows expected to be derived from those assets are less than carrying amounts of these assets.  As of June 30, 2016, there was no impairment to the Company's patents.

Stock-Based Compensation

The Company accounts for its stock-based compensation awards to employees and directors in accordance with FASB ASC Topic 718, Compensation - Stock Compensation ("ASC 718"). ASC 718 requires all stock-based payments to employees, including grants of employee stock options and restricted stock units, to be recognized in the unaudited condensed consolidated statements of operations and comprehensive income (loss) based on their grant date fair values. Compensation expense related to awards to employees is recognized on a straight-line basis based on the grant date fair value over the associated service period of the award, which is generally the vesting term. Share-based payments issued to non-employees are recorded at their fair values, and are periodically revalued as the equity instruments vest and are recognized as expense over the related service period in accordance with the provisions of ASC 718 and ASC Topic 505,  Equity, and are expensed using an accelerated attribution model. The Company uses the Black-Scholes option pricing model to determine the grant date fair value of options granted.  See Note D for further discussion of the Company's stock – based compensation.

Earnings (Loss) Per Share

The Company reports earnings (loss) per share in accordance with U.S. GAAP, which requires presentation of basic and diluted earnings per share in conjunction with the disclosure of the methodology used in computing such earnings (loss) per share. Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average common shares outstanding during the period. Diluted earnings per share takes into account the potential dilution that could occur if securities or other contracts, such as warrants and options to purchase common stock were exercised or restricted stock units were issued. Common stock equivalents having an anti-dilutive effect on earnings per share are excluded from the calculation of diluted earnings per share.

Financial Instruments

U.S. GAAP regarding fair value of financial instruments and related fair value measurements define fair value, establish a three-level valuation hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The three levels of inputs are defined as follows:

Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 inputs to the valuation methodology are unobservable.

The carrying value of cash, marketable securities, royalty receivables, other assets, accounts payable, and accrued expenses approximates fair value because of the short period of time between the origination of such instruments and their expected realization and their current market rates of interest.  Marketable securities available for sale are measured at fair value on a recurring basis based on Level 1 inputs (see Note H).

Reclassification

The Company has reclassified certain amounts in prior period unaudited condensed consolidated financial statements to conform to the current period's presentation.

Recent Accounting Pronouncements

In March 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvement to Employee Share-based Payment Accounting (ASU 2016-09) to simplify the accounting for share-based payment transactions, including the income tax consequences, an option to recognize gross share-based compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. This guidance will be effective for us in the first quarter of 2017, and early adoption is permitted. Management is still evaluating the effect that this guidance will have on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). ASU No. 2016-02 is effective for annual periods beginning after December 15, 2018, and requires a lessee to recognize assets and liabilities for leases with a maximum possible term of more than 12 months. A lessee would recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the leased asset (the underlying asset) for the lease term.

Early application is permitted. The Company is currently evaluating the impact the adoption of the accounting standard will have on its unaudited condensed consolidated financial statements.

In May 2014, FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606).  ASU No. 2014-09 provides for a single comprehensive model for use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance.  The accounting standard is effective for interim and annual periods beginning after December 15, 2016 with no early adoption permitted.  In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date of ASU No. 2014-09 to annual periods beginning after December 2017, along with an option to permit early adoption as of the original effective date.  We are required to adopt the amendments in ASU No. 2014-09 using one of two acceptable methods. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. The ASU clarifies the following two aspects of Topic 606: (a) identifying performance obligations; and (b) the licensing implementation guidance. The ASU does not change the core principle of the guidance in Topic 606. The effective date and transition requirements for the ASU are the same as the effective date and transition requirements in Topic 606. Public entities should apply the ASU for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein (i.e., January 1, 2018, for a calendar year entity). Early application for public entities is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Management is currently in the process of determining which adoption method it will apply and evaluating the impact of the guidance on our consolidated financial statements.

Accounting Standards Adopted in the Period

In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Income Taxes (Topic 740); Balance Sheet Classification of Deferred Taxes (ASU 2015-17), which simplifies the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as noncurrent on the balance sheet.  The updated standard is effective beginning on January 1, 2017 with early application permitted as of the beginning of any interim or annual reporting period. Effective January 1, 2016, the Company has elected to early adopt the standard and classify the deferred tax assets as non-current assets on the condensed consolidated balance sheets.
