Under the Company’s loan policy, loans are placed on nonaccrual status once principal or interest payments become 90 days past due. However, individual loan officers may submit written requests for approval to continue the accrual of interest on loans that become 90 days past due. These requests may be submitted for approval consistent with the authority levels provided in the Company’s credit approval policies, and they are only granted if an expected near term future event, such as a pending renewal or expected payoff, exists at the time the loan becomes 90 days past due. If the expected near term future event does not occur as anticipated, the loan is then placed on nonaccrual status. At September 30, 2011 and December 31, 2010, the Company had $4.1 million and $5.5 million, respectively, of loans past due 90 days or more and still accruing interest.
 
Credit Quality Indicators. The Company’s credit management policies and procedures focus on identifying, measuring and controlling credit exposure. These procedures employ a lender-initiated system of rating credits, which is ratified in the loan approval process and subsequently tested in internal credit reviews, external audits and regulatory bank examinations. The system requires the rating of all loans at the time they are originated or acquired, except for homogeneous categories of loans, such as residential real estate mortgage loans and consumer loans. These homogeneous loans are assigned an initial rating based on the Company’s experience with each type of loan. The Company adjusts the ratings of the homogeneous loans based on payment experience subsequent to their origination.
 
The Company includes adversely rated credits, including loans requiring close monitoring that would not normally be considered classified credits by the Company’s regulators, on its monthly loan watch list. Loans may be added to the Company’s watch list for reasons that are temporary and correctable, such as the absence of current financial statements of the borrower or a deficiency in loan documentation. Loans may also be added to the Company’s watch list whenever any adverse circumstance is detected which might affect the borrower’s ability to comply with the contractual terms of the loan. The delinquency of a scheduled loan payment, deterioration in the borrower’s financial condition identified in a review of periodic financial statements, a decrease in the value of the collateral securing the loan, or a change in the economic environment within which the borrower operates could initiate the addition of a loan to the Company’s watch list. Loans on the Company’s watch list require periodic detailed loan status reports prepared by the responsible officer which are discussed in formal meetings with credit review and credit administration staff members. Upgrades and downgrades of loan risk ratings may be initiated by the responsible loan officer. However, upgrades of risk ratings associated with significant credit relationships and/or problem credit relationships may only be made with the concurrence of appropriate regional or senior regional credit officers.
 
Under the Company’s risk rating system, special mention loans are those loans that do not currently expose the Company to sufficient risk to warrant classification as substandard, troubled debt restructuring (TDR) or nonaccrual, but possess weaknesses that deserve management’s close attention. Substandard loans include those loans characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. A loan is classified as a TDR when a borrower is experiencing financial difficulties that lead to the restructuring of a loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider. Loans classified as TDRs which are accruing interest are classified as performing TDRs. Loans classified as TDRs which are not accruing interest are classified as nonperforming TDRs and included with all other nonaccrual loans for presentation purposes. Loans classified as nonaccrual have all the weaknesses inherent in those loans classified as substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of the currently existing facts, conditions and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass-rated loans.

Impaired Loans. Loans deemed to be impaired include TDRs and nonaccrual loans. Impaired loans with outstanding balances equal to or greater than $500,000 are evaluated individually for impairment. For these loans, the Company measures the level of impairment based on the present value of the estimated projected cash flows or the estimated value of the collateral. If the current valuation is lower than the current book balance of the loan, the negative difference is evaluated for possible charge-off. In instances where management determines that a charge-off is not appropriate, a specific reserve is established for the individual loan in question. This specific reserve is included as a part of the overall allowance for loan losses.

Recorded investment represents the Company’s investment in its impaired loans reduced by any charge-offs recorded against the allowance for loan losses on these same loans. At September 30, 2011 and December 31, 2010, the Company had recorded charge-offs of $104.9 million and $187.9 million, respectively, on its impaired loans, representing the difference between the unpaid principal balance and the recorded investment reflected in the table above. The unpaid principal balance represents the principal amount contractually owed to the Company by the borrowers on the impaired loans.
 
Impaired Loans Acquired in Acquisitions. The outstanding balance and carrying amount of impaired loans acquired in acquisitions was $1.4 million and $314,000, respectively, at December 31, 2010, and $3.0 million and $672,000, respectively, at September 30, 2010. There were no outstanding impaired loans acquired in acquisitions at September 30, 2011 and there were no impaired loans acquired during the three and nine months ended September 30, 2011 and 2010. As the loans were classified as nonaccrual loans, there was no accretable yield related to these loans at December 31, 2010. Changes in the carrying amount of impaired loans acquired in acquisitions for the three and nine months ended September 30, 2011 and 2010 were as follows:
 
  Three Months Ended       Nine Months Ended

Balance, end of period $     672         672  
                         
Troubled debt restructurings. In the ordinary course of business, the Company modifies loan terms across loan types, including both consumer and commercial loans, for a variety of reasons. Modifications to consumer loans may include, but are not limited to, changes in interest rate, maturity, amortization and financial covenants. In the original underwriting, loan terms are established that represent the then current and projected financial condition of the borrower. Over any period of time, modifications to these loan terms may be required due to changes in the original underwriting assumptions. These changes may include the financial requirements of the borrower as well as underwriting standards. If the modified terms are consistent with competitive market conditions and representative of terms the borrower could otherwise obtain in the open market, the modified loan is not categorized as a TDR.
 
Loan modifications are generally performed at the request of the individual borrower and may include reduction in interest rates, changes in payments and maturity date extensions. Although the Company does not have formal, standardized loan modification programs for its commercial or consumer loan portfolios, it participates in the U.S. Department of the Treasury’s (U.S. Treasury) Home Affordable Modification Program (HAMP). HAMP gives qualifying homeowners an opportunity to refinance into more affordable monthly payments, with the U.S. Treasury compensating the Company for a portion of the reduction in monthly amounts due from borrowers participating in this program. At September 30, 2011 and December 31, 2010, the Company had $73.4 million and $64.2 million, respectively, of modified loans in HAMP.
 
For a loan modification to be classified as a TDR, all of the following conditions must be present: (1) the borrower is experiencing financial difficulty, (2) the Company makes a concession to the original contractual loan terms and (3) the Company would not consider the concessions but for economic or legal reasons related to the borrower’s financial difficulty. Modifications of loan terms to borrowers experiencing financial difficulty are made in an attempt to protect as much of the investment in the loan as possible. These modifications are generally made to either prevent a loan from becoming nonaccrual or to return a nonaccrual loan to performing status based on the expectations that the borrower can adequately perform in accordance with the modified terms.
 
The determination of whether a modification should be classified as a TDR requires significant judgment after taking into consideration all facts and circumstances surrounding the transaction. No single characteristic or factor, taken alone, is determinative of whether a modification should be classified as a TDR. The fact that a single characteristic is present is not considered sufficient to overcome the preponderance of contrary evidence. Assuming all of the TDR criteria are met, the Company considers one or more of the following concessions to the loan terms to represent a TDR: (1) a reduction of the stated interest rate, (2) an extension of the maturity date or dates at a stated interest rate lower than the current market rate for a new loan with similar terms or (3) forgiveness of principal or accrued interest.
 
Loans renegotiated at a rate equal to or greater than that of a new loan with comparable risk at the time the contract is modified are excluded from TDR classification in the calendar years subsequent to the renegotiation if the loan is in compliance with the modified terms for at least six months.
 
The Company does not accrue interest on any TDRs unless it believes collection of all principal and interest under the modified terms is reasonably assured. Generally, six months of consecutive payment performance by the borrower under the restructured terms is required before a TDR is returned to accrual status. However, the period could vary depending upon the individual facts and circumstances of the loan. TDRs accruing interest are classified as performing TDRs. The following table presents the categories of performing TDRs as of September 30, 2011 and December 31, 2010:
 
  September 30,        December 31,
  2011   2010
  (dollars expressed in thousands)
Commercial, financial and agricultural $       4,519  
Real estate construction and development   3,144   3,145

    Commercial real estate   2,701   18,429
       Total performing troubled debt restructurings $ 94,900   112,903
         
The Company does not accrue interest on TDRs which have been modified for a period less than six months or are not in compliance with the modified terms. These loans are considered nonperforming TDRs and are included with other nonaccrual loans for classification purposes. The following table presents the categories of loans considered nonperforming TDRs as of September 30, 2011 and December 31, 2010:
 
  September 30,        December 31,
  2011   2010
  (dollars expressed in thousands)
Commercial, financial and agricultural $       1,555   5,432
Real estate construction and development   7,496          9,927
Real estate mortgage:        
    One-to-four family residential   4,872   4,923
    Commercial real estate   8,968   5,909
       Total nonperforming troubled debt restructurings $ 22,891   26,191
         
Both performing and nonperforming TDRs are considered to be impaired loans. When an individual loan is determined to be a TDR, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the underlying collateral less applicable selling costs. The impairment amount is either charged off as a reduction to the allowance for loan losses or provided for as a specific reserve within the allowance for loan losses. The allowance for loan losses allocated to TDRs was $11.2 million and $11.4 million at September 30, 2011 and December 31, 2010, respectively.

Upon default of a TDR, which is considered to be 90 days or more past due under the modified terms, impairment is measured based on the fair value of the underlying collateral less applicable selling costs. The impairment amount is either charged off as a reduction to the allowance for loan losses or provided for as a specific reserve within the allowance for loan losses.
 
Allowance for Loan Losses. The allowance for loan losses is a reserve for estimated credit losses on individually evaluated loans determined to be impaired as well as estimated credit losses inherent in the loan portfolio, and is based on quarterly evaluations of the collectability and historical loss experience of loans. Actual credit losses, net of recoveries, are deducted from the allowance for loan losses. A provision for loan losses, which is a charge against earnings, is recorded to bring the allowance for loan losses to a level that, in management’s judgment, is appropriate to absorb probable losses in the loan portfolio.
 
The allocation methodology applied by the Company, designed to assess the appropriateness of the allowance for loan losses, includes an allocation methodology, as well as management’s ongoing review and grading of the loan portfolio into criticized loan categories (defined as specific loans warranting either specific allocation, or a criticized status of special mention, substandard, doubtful or loss). The allocation methodology focuses on evaluation of several factors, including but not limited to: evaluation of facts and circumstances related to specific loans, management’s ongoing review and grading of the loan portfolio, consideration of historical loan loss and delinquency experience within each portfolio category, trends in past due and nonaccrual loans, the level of potential problem loans, the risk characteristics of the various classifications of loans, changes in the size and character of the loan portfolio, concentrations of loans to specific borrowers or industries, existing economic conditions, the fair value of underlying collateral, and other qualitative and quantitative factors which could affect potential credit losses. Because each of the criteria used is subject to change, the allocation of the allowance for loan losses is made for analytical purposes and is not necessarily indicative of the trend of future loan losses in any particular loan category. The total allowance for loan losses is available to absorb losses from any segment of the loan portfolio.
 
When an individual loan is determined to be impaired, the allowance for loan losses attributable to the loan is allocated based on management’s estimate of the borrower’s ability to repay the loan given the availability of collateral, other sources of cash flows, as well as evaluation of legal options available to the Company. The amount of impairment is measured based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the fair value of the underlying collateral less applicable selling costs, or the observable market price of the loan. If foreclosure is probable or the loan is collateral dependent, impairment is measured using the fair value of the loan’s collateral, less estimated costs to sell. Large groups of homogeneous loans, such as residential mortgage, home equity and installment loans, are aggregated and collectively evaluated for impairment.
