Goodwill and Other Intangible Assets
Goodwill and Other Intangible Assets
We have accounted for the Merger as a business combination under the acquisition method of accounting. As a result, we have recognized in our financial statements the identifiable net assets acquired and an amount of goodwill (representing the difference between the purchase price and the identifiable net assets). During the measurement period following a business combination, the amount of identifiable net assets recognized is subject to further adjustment to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. Generally accepted accounting principles (“GAAP”) require that the measurement period cannot exceed one year from the acquisition date.
During the period ending March 31, 2012, we recognized $0.3 million in additional goodwill from the Merger. This additional amount was due to new valuations received on OREO acquired in the Merger, which were written down to our best estimate of fair value.
Goodwill and other intangible assets deemed to have indefinite lives generated from purchase business combinations are not subject to amortization and are instead tested for impairment no less than annually. Impairment exists when the carrying value of goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess and would be included in noninterest expense in the Consolidated Statements of Operations. None of the goodwill recognized in the Merger is expected to be deductible for income tax purposes.
Our intangible assets with definite lives are core deposit premiums ("CDP"). This intangible asset is amortized over its useful life to its estimated residual value and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits.
For intangible assets related to business combinations, the following table presents the changes in CDP and the related accumulated amortization for the periods indicated:
