Goodwill was adjusted based on additional information received in 2011 relating to the acquisition date value of certain assets and liabilities. Refer to Note 1, “Summary of Significant Accounting Policies,” for further details of this adjustment.

Goodwill is not amortized but is subject to impairment testing on an annual basis or more often if events or circumstances indicate the potential for impairment. Due to volatile market conditions and a decline in the Company’s market capitalization, management determined that an interim impairment test of goodwill as of September 30, 2011 was appropriate. The testing was performed by comparing the carrying value of the reporting unit with management’s estimate of the fair value of the reporting unit, which was based on a discounted cash flow analysis. Step 1 of the interim test indicated that management’s estimate of the fair value of the reporting unit exceeded the carrying value of the reporting unit; therefore, no impairment existed, and Step 2 of the impairment test was not required.

The Company’s annual impairment test date is October 1. Given the proximity of the interim test to the annual test date and management’s evaluation of market conditions, no additional goodwill impairment testing was deemed necessary during the fourth quarter of 2011.

The Company’s other intangible assets are core deposit premiums, which are being amortized over their estimated useful lives. The Company reviews intangible assets at least annually for possible impairment or more often if events or changes in circumstances between tests indicate that carrying amounts may not be recoverable. The Company’s annual impairment testing was performed as of November 30, 2011 by comparing the carrying value of intangibles with our anticipated discounted future cash flows, and it was determined that no impairment existed as of that date.

In December 2011, the Company completed the purchase of certain Chicago-market deposits from Old National. The transaction included $106.7 million in deposits (comprised of $70.6 million in core transactional deposits and $36.1 in time deposits) and one banking facility located in the market in which the Company operates. As a result of the transaction, the Company recorded $1.4 million in core deposit intangibles and a net gain of $1.1 million.
