Goodwill
 
As of December 31, 2014 and 2013, the carrying amounts of goodwill were $469.4 million and $337.4 million, respectively. The increase of $132.0 million to goodwill was due to the acquisition of MetroCorp as discussed in Note 2 to the Company’s consolidated financial statements.

The Company has identified three business divisions, Retail Banking, Commercial Banking, and Other, that meet the criteria of an operating segment in accordance with GAAP. The Company determined that there were no additional reporting units below each operating segment and therefore the reporting units are equivalent to the operating segments. For complete discussion and disclosure see Note 20 to the Company’s consolidated financial statements presented elsewhere in this report.
 
The Company performed its annual impairment test as of December 31, 2014 to determine whether and to what extent, if any, recorded goodwill was impaired. The Company uses a combined income and market approach to determine the fair value of the reporting units. Under the income approach, the Company provided a net income projection for the next three years plus a terminal growth rate that was used to calculate the discounted cash flows and the present value of the reporting units. Under the market approach, the fair value was calculated using the current fair values of comparable peer banks of similar size, geographic footprint and focus. The market capitalizations and multiples of these peer banks were used to calculate the market price of the Company and each reporting unit. The fair value was also subject to a control premium adjustment, which is the cost savings that a purchaser of the reporting units could achieve by eliminating duplicative costs. Under the combined income and market approaches, the value from each approach was weighted based on management's perceived risk of each approach to determine the fair value. As a result of this analysis, the Company determined that there was no goodwill impairment as of December 31, 2014 as the fair values of all reporting units exceeded the current carrying amounts of the goodwill. No assurance can be given that goodwill will not be written down in future periods.

Premiums on Acquired Deposits
 
Premiums on acquired deposits 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 December 31, 2014 and 2013, the gross carrying amount of premiums on acquired deposits were $108.8 million and $100.2 million, respectively, and the related accumulated amortization totaled $63.5 million and $53.3 million, respectively. A premium on acquired deposits of $8.6 million was recorded due to the acquisition of MetroCorp as discussed in Note 2 to the Company’s consolidated financial statements. The weighted-average amortization period related to MetroCorp's premium on acquired deposits is eight years.
 

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 $10.2 million, $9.4 million and $10.9 million for the years ended December 31, 2014, 2013 and 2012, respectively. The Company did not record any impairment write-downs on deposit premiums for the years ended December 31, 2014, 2013 and 2012.
