ASC 805

ASC 805 prescribes the acquisition method for accounting for business combinations. The acquirer identifies itself, determines the acquisition date, recognizes and measures the identifiable assets acquired and liabilities assumed at fair value, recognizes any non-controlling interest, and recognizes goodwill as the residual - or a bargain purchase gain in the rare case where the fair value of net assets exceeds consideration transferred.

The threshold question is whether the transaction involves a business or merely a group of assets. The screen test asks whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar assets; if so, the transaction is an asset acquisition, and no goodwill arises. This distinction drives materially different accounting for transaction costs, contingent consideration, and in-process research and development.

Purchase accounting work is valuation-intensive. Intangible assets that were never on the target's balance sheet - customer relationships, developed technology, trade names, non-compete agreements, backlog — must be identified, valued, and assigned useful lives. Contingent consideration is measured at fair value at acquisition and, if classified as a liability, remeasured through earnings each period. Deferred taxes must be established on the difference between the new book basis and the carryover tax basis, unless the transaction is a taxable asset acquisition or a section 338 election applies.

The measurement period allows up to one year to finalize provisional amounts as new information about acquisition-date facts emerges. For CPA firms, ASC 805 engagements combine technical accounting, valuation specialist coordination, and tax structuring analysis.
