GOODWILL AND OTHER INTANGIBLE ASSETS
NOTE 10 - GOODWILL AND OTHER INTANGIBLE ASSETS
 
Goodwill
 
The carrying amount of goodwill remained at $337.4 million as of June 30, 2011 and December 31, 2010. Goodwill is tested for impairment on an annual basis as of December 31, or more frequently as events occur, or as current circumstances and conditions warrant. The Company records impairment write-downs as charges to noninterest expense and adjustments to the carrying value of goodwill. Subsequent reversals of goodwill impairment are prohibited.
 
As of June 30, 2011, the Company's market capitalization based on total outstanding common and preferred shares was $2.94 billion and its total stockholders' equity was $2.23 billion. The Company performed its annual impairment test as of December 31, 2010 to determine whether and to what extent, if any, recorded goodwill was impaired. The analysis compared the fair value of each of the reporting units, including goodwill, to the respective carrying amounts. If the carrying amount of the reporting unit, including goodwill, exceeds the fair value of that reporting unit, then further testing for goodwill impairment is performed.
 
Premiums on Acquired Deposits
 
The Company also has premiums on acquired deposits, which represent the intangible value of depositor relationships resulting from deposit liabilities assumed in various acquisitions. These intangibles are tested for impairment on an annual basis, or more frequently as events occur, or as current circumstances and conditions warrant. As of June 30, 2011 and December 31, 2010, the gross carrying amount of premiums on acquired deposits totaled $117.6 million and $117.6 million, respectively, and the related accumulated amortization totaled $44.5 million and $38.1 million, respectively.
 
The Company amortizes premiums on acquired deposits based on the projected useful lives of the related deposits. Amortization expense of premiums on acquired deposits was $3.1 million and $3.3 million for the three months ended June 30, 2011 and 2010, respectively, and $6.3 million and $6.7 million for the six months ended June 30, 2011 and 2010, respectively.
 
The following table provides the estimated future amortization expense of premiums on acquired deposits for the succeeding five years and thereafter:
