The Company measures the amount of impairment by evaluating loans either in their collective homogeneous pools or individually. At September 30, 2011, the Company had $287.9 million in loans considered to be impaired of which $8.1 million were collectively evaluated for impairment and $279.8 million were individually evaluated for impairment. The following table shows the Company's impaired loans individually evaluated for impairment, by class, at September 30, 2011 (dollars in thousands):

At December 31, 2010, the Company had $284.6 million in loans considered to be impaired of which $9.7 million were collectively evaluated for impairment and $274.9 million were individually evaluated for impairment.

On July 1, 2011, the Company adopted the amendments in Accounting Standards Update No. 2011-02 A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring ("ASU 2011-02"). As a result of adopting the amendments in ASU 2011-02, the Company reassessed all loans that were renewed on or after January 1, 2011 for identification as a troubled debt restructuring ("TDR"). The Company identified as troubled debt restructurings certain loans for which impairment had previously been measured collectively within their homogeneous pool. Upon identifying those loans as TDRs, the Company identified them as impaired under the guidance in ASC 310-10-35. The amendments in ASU 2011-02 require prospective evaluation of the impairment measurement guidance for those receivables newly identified as impaired. At September 30, 2011, the recorded investment in loans for which the allowance for credit losses were previously measured collectively within their homogeneous pool and now considered impaired, due to being designated as a TDR, was $21.4 million, and the allowance for credit losses associated with those loans, on the basis of a current evaluation of loss, was $275,000. The impact of this new guidance did not have a material impact on the Company's non-performing assets, allowance for loan losses, earnings, or capital.

The Company considers troubled debt restructurings to be impaired loans. A modification of a loan's terms constitutes a TDR if the creditor grants a concession to the borrower for economic or legal reasons related to the borrower's financial difficulties that it would not otherwise consider. Included in the impaired loan disclosure above are $116 million of loans considered to be troubled debt restructurings as of September 30, 2011. All loans that are considered to be TDRs are specifically evaluated for impairment in accordance with the Company's allowance for loan loss methodology.

The following table provides a summary of modified loans that continue to accrue interest under the terms of the restructuring agreement, which are considered to be performing, and modified loans that have been placed in nonaccrual status, which are considered to be nonperforming, as of September 30, 2011 (dollars in thousands):

The following table shows, by class, TDRs that occurred during the three and nine month periods ended September 30, 2011 (dollars in thousands):

The primary modification to each loan class identified as TDRs during the period related to a renewal at the current terms and those terms were considered to be below market based on the risk characteristics of the borrower. Generally, the Company does not modify interest rates or reduce principal balances when restructuring loans thus the recorded investment is unchanged after the modification is made. There were no TDRs that were restructured during the previous twelve months for which there was a payment default in the three and nine month periods ended September 30, 2011. A default for purposes of this disclosure is a TDR in which subsequent to the restructure, the borrower is 90 days past due or results in foreclosure and repossession of the applicable collateral.

The following table shows the allowance for loan loss activity, by portfolio segment, balances for allowance for credit losses, and loans based on impairment methodology for the nine months ended September 30, 2011.
