These estimates include contract liabilities related to product sales, useful lives for property and equipment and related depreciation calculations, assumptions for valuing options and warrants, the fair value of contingent consideration, intangible assets, and goodwill, stock-based compensation, income taxes and other contingencies These estimates are based on management’s best estimates and judgment.

Upon recognition of product sales, contract liabilities are recorded for invoiced amounts that are subject to significant reversal, including product revenue allowances for cash consideration paid to customers for services, discounts, rebate programs, and product returns.

The expense associated with these grants is recognized in the Company’s consolidated statements of stockholders’ equity based on their fair values as they are earned under the applicable vesting terms.

These values are subject to a significant degree of management’s judgment. Net Loss per Share The Company computes net loss per share by presenting both basic and diluted earnings (loss) per share (“EPS”). Basic EPS is computed by dividing net loss available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period, including stock options and warrants, using the treasury stock method. In computing diluted EPS, the average stock price for the period is used to determine the number of shares assumed to be purchased from the exercise of stock options or warrants. Potentially dilutive common share equivalents are excluded from the diluted EPS computation in net loss periods because their effect would be anti-dilutive.
