Revenue is measured as the amount of consideration the Company expects to be entitled to in exchange for those goods. The Company’s contracts do not involve financing elements as payment terms with customers are less than one year. The sale arrangements do not include any variable consideration. Advance payments from customers are recorded as deferred revenue. Shipping and handling activities that occur after the customer obtains control of the goods are considered part of the Company’s obligation to transfer the products and therefore are recorded as direct selling expenses, as incurred.

Recently Issued Accounting Pronouncements

In February 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, to simplify how all entities assess goodwill for impairment by eliminating Step 2 from the goodwill impairment test.

Recently Adopted Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases. Under this new guidance, at the commencement date, lessees will be required to recognize (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term.

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions affecting 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 revenue and expenses during the reporting period. Our most significant estimates and critical accounting policies involve recognizing revenue, reviewing goodwill and intangible assets for impairment, determining the assumptions used in measuring share-based compensation expense, valuing warrants, measuring expense related to our in-process research and development acquisition, and valuing allowances for doubtful accounts and inventory reserves.
