Certain premium finance receivables are recorded net of unearned income. The unearned income portions of such premium finance receivables were $40.0 million at March 31, 2013, $41.1 million at December 31, 2012 and $36.8 million at March 31, 2012, respectively. Certain life insurance premium finance receivables attributable to the life insurance premium finance loan acquisition in 2009 as well as the covered loans acquired in the FDIC-assisted acquisitions are recorded net of credit discounts. See “Acquired Loan Information at Acquisition” below.

Indirect consumer loans include auto, boat and other indirect consumer loans. Total loans, excluding loans acquired with evidence of credit quality deterioration since origination, include net deferred loan fees and costs and fair value purchase accounting adjustments totaling $10.5 million at March 31, 2013, $13.2 million at December 31, 2012 and $12.6 million at March 31, 2012.

The Company’s loan portfolio is generally comprised of loans to consumers and small to medium-sized businesses located within the geographic market areas that the banks serve. The premium finance receivables portfolios are made to customers on a national basis and the majority of the indirect consumer loans were generated through a network of local automobile dealers. As a result, the Company strives to maintain a loan portfolio that is diverse in terms of loan type, industry, borrower and geographic concentrations. Such diversification reduces the exposure to economic downturns that may occur in different segments of the economy or in different industries.

It is the policy of the Company to review each prospective credit in order to determine the appropriateness and, when required, the adequacy of security or collateral necessary to obtain when making a loan. The type of collateral, when required, will vary from liquid assets to real estate. The Company seeks to ensure access to collateral, in the event of default, through adherence to state lending laws and the Company’s credit monitoring procedures.

Acquired Loan Information at Acquisition—Loans with evidence of credit quality deterioration since origination

As part of our previous acquisitions, we acquired loans for which there was evidence of credit quality deterioration since origination and we determined that it was probable that the Company would be unable to collect all contractually required principal and interest payments.

The following table presents the unpaid principal balance and carrying value for these acquired loans:



	March 31, 2013				December 31, 2012
	Unpaid Principal		Carrying		Unpaid Principal		Carrying
(Dollars in thousands)	Balance		Value		Balance		Value
Bank acquisitions	$	612,702	$	462,129	$	674,868	$	503,837

See Note 7—Allowance for Loan Losses, Allowance for Losses on Lending-Related Commitments and Impaired Loans for further discussion regarding the allowance for loan losses associated with loans acquired with evidence of credit quality deterioration since origination at March 31, 2013.

Accretable Yield Activity

Changes in expected cash flows may vary from period to period as the Company periodically updates its cash flow model assumptions for loans acquired with evidence of credit quality deterioration since origination. The factors that most significantly affect the estimates of gross cash flows expected to be collected, and accordingly the accretable yield, include changes in the benchmark interest rate indices for variable-rate products and changes in prepayment assumptions and loss estimates. The following table provides activity for the accretable yield of loans acquired with evidence of credit quality deterioration since origination:



	Three Months Ended March 31, 2013						Three Months Ended March 31, 2012
(Dollars in thousands)	Bank Acquisitions			Life Insurance Premium Finance Loans			Bank Acquisitions			Life Insurance Premium Finance Loans
Accretable yield, beginning balance	$	143,224		$	13,055		$	173,120		$	18,861

Accretable yield amortized to indemnification asset ⁽¹⁾	(8,706		)	—			(21,377		)	—

Accretable yield, ending balance ⁽³⁾	$	121,725		$	11,218		$	182,222		$	15,848


(1)	Represents the portion of the current period accreted yield, resulting from lower expected losses, applied to reduce the loss share indemnification asset.


(2)	Reclassification is the result of subsequent increases in expected principal cash flows.


(3)	As of March 31, 2013, the Company estimates that the remaining accretable yield balance to be amortized to the indemnification asset for the bank acquisitions is $42.9 million. The remainder of the accretable yield related to bank acquisitions is expected to be amortized to interest income.
