Goodwill and Other Acquired Intangible Assets [Abstract]
GOODWILL	NOTE 6 — GOODWILL Goodwill was $113.4 million at December 31, 2011 and 2010. During 2010, the Corporation acquired OAK, which resulted in the recognition of $43.5 million of goodwill. Goodwill recognized in the OAK acquisition was primarily attributable to the synergies and economies of scale expected from combining the operations of the Corporation and OAK. No amount of goodwill recorded in conjunction with the OAK acquisition is deductible for tax purposes. Goodwill is subject to impairment testing annually and on an interim basis if events or changes in circumstances indicate assets might be impaired. The Corporation’s most recent goodwill impairment test performed as of October 31, 2011 did not indicate that an impairment of goodwill existed. The Corporation also determined that no triggering events occurred that indicated impairment from the most recent valuation date through December 31, 2011 and that the Corporation’s goodwill was not impaired at December 31, 2011. Refer to Note 1 under the heading “Goodwill” for information regarding the Corporation’s change in the date of its annual impairment test.
