The Company had loans of $62.8 billion at September 30, 2011, and December 31, 2010, pledged at the Federal Home Loan Bank (“FHLB”), and loans of $46.1 billion at September 30, 2011, and $44.6 billion at December 31, 2010, pledged at the Federal Reserve Bank.
Net gains on the sale of loans of $74 million and $105 million for the three months ended September 30, 2011 and 2010, respectively, and $340 million and $308 million for the nine months ended September 30, 2011 and 2010, respectively, were included in noninterest income, primarily in mortgage banking revenue.
Originated loans are presented net of unearned interest and deferred fees and costs, which amounted to $1.1 billion at September 30, 2011, and $1.3 billion at December 31, 2010. In accordance with applicable authoritative accounting guidance, all purchased loans and related indemnification assets are recorded at fair value at the date of purchase. The Company evaluates purchased loans for impairment at the date of purchase in accordance with applicable authoritative accounting guidance. Purchased loans with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are considered “purchased impaired loans”. All other purchased loans are considered “purchased nonimpaired loans”.
Covered assets represent loans and other assets acquired from the FDIC subject to loss sharing agreements in the Downey Savings and Loan Association, F.A.; PFF Bank and Trust; and First Bank of Oak Park Corporation transactions and included expected reimbursements from the FDIC of approximately $2.4 billion at September 30, 2011 and $3.1 billion at December 31, 2010.
 
The carrying amount of the covered assets consisted of purchased impaired loans, purchased nonimpaired loans, and other assets as shown in the following table:

At September 30, 2011, $.3 billion of the purchased impaired loans included in covered loans were classified as nonperforming assets, compared with $.5 billion at December 31, 2010, because the expected cash flows are primarily based on the liquidation of underlying collateral and the timing and amount of the cash flows could not be reasonably estimated. Interest income is recognized on other purchased impaired loans through accretion of the difference between the carrying amount of those loans and their expected cash flows. The initial determination of the fair value of the purchased loans includes the impact of expected credit losses and, therefore, no allowance for credit losses is recorded at the purchase date. To the extent credit deterioration occurs after the date of acquisition, the Company records an allowance for credit losses.
On the acquisition date, the estimate of the contractually required payments receivable for all purchased impaired loans acquired in the FCB transaction were $502 million, the cash flows expected to be collected were $338 million including interest, and the estimated fair values of the loans were $238 million. These amounts were determined based upon the estimated remaining life of the underlying loans, which includes the effects of estimated prepayments. For the purchased nonimpaired loans acquired in the FCB transaction, the estimate as of the acquisition date of the contractually required payments receivable were $1.2 billion, the contractual cash flows not expected to be collected were $184 million, and the estimated fair value of the loans was $828 million.
 
Changes in the accretable balance for all purchased impaired loans, including those acquired in the FCB transaction, were as follows:

The allowance for credit losses reserves for probable and estimable losses incurred in the Company’s loan and lease portfolio and includes certain amounts that do not represent loss exposure to the Company because those losses are recoverable under loss sharing agreements with the FDIC. The allowance for credit losses is increased through provisions charged to operating earnings and reduced by net charge-offs. Management evaluates the allowance each quarter to ensure it appropriately reserves for incurred losses.
The allowance recorded for loans in the commercial lending segment is generally based on quarterly reviews of individual credit relationships and considers the migration analysis of commercial lending segment loans and actual loss experience. The Company currently uses an 11 year period of historical losses in considering actual loss experience. This timeframe and the results of the analysis are evaluated quarterly to determine the appropriateness. The allowance recorded for impaired loans greater than $5 million in the commercial lending segment is based on an individual loan analysis utilizing expected cash flows discounted using the original effective interest rate, the observable market price, or the fair value of the collateral for collateral-dependent loans. The allowance recorded for all other commercial lending segment loans is determined on a homogenous pool basis and includes consideration of product mix, risk characteristics of the portfolio, bankruptcy experience, and historical losses, adjusted for current trends. The Company also considers the impacts of any loan modifications made to commercial lending segment loans and any subsequent payment defaults to its expectations of cash flows, principal balance, and current expectations about the borrower’s ability to pay in determining the allowance for credit losses.
The allowance recorded for purchased impaired and TDR loans in the consumer lending segment is determined on a homogenous pool basis utilizing expected cash flows discounted using the original effective interest rate of the pool. The allowance recorded for all other consumer lending segment loans is determined on a homogenous pool basis and includes consideration of product mix, risk characteristics of the portfolio, bankruptcy experience, and historical losses, adjusted for current trends. The Company also considers any modifications made to consumer lending segment loans including the impacts of any subsequent payment defaults since modification in determining the allowance for credit losses, such as borrower’s ability to pay under the restructured terms, and the timing and amount of payments.
The allowance for covered segment loans is evaluated each quarter in a manner similar to that described for non-covered loans and represents any decreases in expected cash flows of those loans after the acquisition date. The provision for credit losses for covered segment loans considers the indemnification provided by the FDIC.
The Company’s methodology for determining the appropriate allowance for credit losses for all the loan segments also considers the imprecision inherent in the methodologies used. As a result, in addition to the amounts determined under the methodologies described above, management also considers the potential impact of other qualitative factors which include, but are not limited to, economic factors; geographic and other concentration risks; delinquency and nonaccrual trends; current business conditions; changes in lending policy, underwriting standards, internal review and other relevant business practices; and the regulatory environment. The consideration of these items results in adjustments to allowance amounts included in the Company’s allowance for credit losses for each of the above loan segments.
The Company also assesses the credit risk associated with off-balance sheet loan commitments, letters of credit, and derivatives. Credit risk associated with derivatives is reflected in the fair values recorded for those positions. The liability for off-balance sheet credit exposure related to loan commitments and other credit guarantees is included in other liabilities. Because business processes and credit risks associated with unfunded credit commitments are essentially the same as for loans, the Company utilizes similar processes to estimate its liability for unfunded credit commitments.

Credit Quality The quality of the Company’s loan portfolios is assessed as a function of net credit losses, levels of nonperforming assets and delinquencies, and credit quality ratings as defined by the Company. These credit quality ratings are an important part of the Company’s overall credit risk management process and evaluation of its allowance for credit losses.
For all loan classes, loans are considered past due based on the number of days delinquent except for monthly amortizing loans which are classified delinquent based upon the number of contractually required payments not made (for example, two missed payments is considered 30 days delinquent).
Commercial lending segment loans are placed on nonaccrual status when the collection of principal and interest has become 90 days past due or is otherwise considered doubtful. When a loan is placed on nonaccrual status, unpaid accrued interest is reversed. Commercial lending segment loans are generally fully or partially charged down to the fair value of the collateral securing the loan, less costs to sell, when the loan is considered uncollectible.
Consumer lending segment loans are generally charged-off at a specific number of days or payments past due. Residential mortgages and other retail loans secured by 1-4 family properties are generally charged down to fair market value, less costs to sell, at 180 days past due, and placed on nonaccrual status in instances where a partial charge-off occurs unless the loan is well secured and in the process of collection. Credit card loans continue to accrue interest until the account is charged off. Credit cards are charged off at 180 days past due. Other retail loans not secured by 1-4 family properties are charged-off at 120 days past due; and revolving consumer lines are charged off at 180 days past due. Similar to credit cards, other retail loans are generally not placed on nonaccrual status because of the relative short period of time to charge-off. Certain retail customers having financial difficulties may have the terms of their credit card and other loan agreements modified to require only principal payments and, as such, are reported as nonaccrual.
For all loan classes, interest payments received on nonaccrual loans are generally recorded as a reduction to the loan carrying amount. Interest payments recorded as reductions to a loan’s carrying amount while a loan is on nonaccrual are recognized as interest income only upon payoff of the loan. In certain circumstances, loans in any class may be restored to accrual status, such as when none of the principal and interest is past due and prospects for future payment are no longer in doubt; or the loan becomes well secured and is in the process of collection. Loans where there has been a partial charge-off may be returned to accrual status if all principal and interest (including amounts previously charged-off) is expected to be collected and the loan is current.
Covered loans not considered to be purchased impaired are evaluated for delinquency, nonaccrual status and charge-off consistent with the class of loan they would be included in had the loss share coverage not been in place. Generally, purchased impaired loans are considered accruing loans. However, the timing and amount of future cash flows for some loans is not reasonably estimable. Those loans are classified as nonaccrual loans and interest income is not recognized until the timing and amount of the future cash flows can be reasonably estimated.

The Company classifies its loan portfolios using internal credit quality ratings on a quarterly basis. These ratings include: pass, special mention and classified, and are an important part of the Company’s overall credit risk management process and evaluation of the allowance for credit losses. Loans with a pass rating represent those not classified on the Company’s rating scale for problem credits, as minimal credit risk has been identified. Special mention loans are those that have a potential weakness deserving management’s close attention. Classified loans are those where a well-defined weakness has been identified that may put full collection of contractual cash flows at risk. It is possible that others, given the same information, may reach different reasonable conclusions regarding the credit quality rating classification of specific loans.

For all loan classes, a loan is considered to be impaired when, based on current events or information, it is probable the Company will be unable to collect all amounts due per the contractual terms of the loan agreement. Impaired loans include all nonaccrual and TDR loans. For all loan classes, interest income on TDR loans is recognized under the modified terms and conditions if the borrower has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles. Interest income is not recognized on other impaired loans until the loan is paid off.
Factors used by the Company in determining whether all principal and interest payments due on commercial and commercial real estate loans will be collected and therefore whether those loans are impaired, include but are not limited to, the financial condition of the borrower, collateral and/or guarantees on the loan, and the borrower’s estimated future ability to pay based on industry, geographic location and certain financial ratios. The evaluation of impairment on residential mortgages, credit card and other retail loans is primarily driven by delinquency status of individual loans or whether a loan has been modified. Individual covered loans, whose future losses are covered by loss sharing agreements with the FDIC that substantially reduce the risk of credit losses to the Company, are evaluated for impairment and accounted for in a manner consistent with the class of loan they would have been included in had the loss sharing coverage not been in place.

Troubled Debt Restructurings In certain circumstances, the Company may modify the terms of a loan to maximize the collection of amounts due when a borrower is experiencing financial difficulties or is expected to experience difficulties in the near-term. Concessionary modifications are classified as TDRs unless the modification results in only an insignificant delay in payments to be received. The Company accrues interest on TDRs if the borrower complies with the revised terms and conditions as agreed upon with the Company and has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles. To the extent a previous restructuring was insignificant, the Company considers the cumulative effect of past restructurings related to the receivable when determining whether a current restructuring is a TDR. Loans classified as TDRs are considered impaired loans for reporting and measurement purposes.

(a) Includes accrued interest and/or outstanding advances capitalized into the outstanding loan balance upon modification under the HAMP program of $32 million and $85 million for the three and nine months ended September 30, 2011, respectively.
Many of the Company’s TDRs are determined on a case-by-case basis in connection with ongoing loan collection processes. However, the Company has also implemented certain restructuring programs that may result in TDRs. The modifications made to each of the loans presented in the table above varies within each of the portfolio classes, however, generally result in revisions to interest rates, changes to payment frequency, extensions of maturity dates, forgiveness of accrued interest and/or fees, and in limited circumstances, reductions of principal.
For the commercial lending segment, modifications generally result in the Company working with borrowers on a case-by-case basis. Commercial and commercial real estate modifications generally include extensions of the maturity date and may be accompanied by an increase or decrease to the interest rate, which may not be deemed a market rate of interest. In addition, the Company may work with the borrower in identifying other changes that mitigate loss to the Company, which may include additional collateral or guarantees to support the loan. To a lesser extent, the Company may waive contractual principal. The Company classifies these concessions as TDRs to the extent the Company determines that the borrower is experiencing financial difficulty.
Modifications for the consumer lending segment are generally part of programs the Company has initiated. The Company participates in the U.S. Department of Treasury Home Affordable Modification Program (“HAMP”). HAMP gives qualifying homeowners an opportunity to permanently modify their loan and achieve more affordable monthly payments, with the U.S. Department of Treasury compensating the Company for a portion of the reduction in monthly amounts due from borrowers participating in this program. The Company also modifies residential mortgage loans under Federal Housing Administration, Department of Veterans Affairs, or other internal programs. Under these programs, the Company provides concessions to qualifying borrowers experiencing financial difficulties. The concessions may include adjustments to interest rates, conversion of adjustable rates to fixed rates, extension of maturity dates or deferrals of payments, capitalization of accrued interest and/or outstanding advances, or in limited situations, partial forgiveness of loan principal. In most instances, participation in residential mortgage loan restructuring programs requires the customer to complete a short-term trial period. A permanent loan modification is contingent on the customer successfully completing the trial period arrangement and the loan documents are not modified until that time. Loans in trial period arrangements are not reported as TDRs. Loans permanently modified are reported as TDRs. Loans in trial period arrangements were $96 million at September 30, 2011.
Credit card and other retail loan modifications are generally part of two distinct restructuring programs. The Company offers workout programs providing customers experiencing financial difficulty with modifications whereby balances may be amortized up to 60 months, and generally include waiver of fees and reduced interest rates. The Company also provides modification programs to qualifying customers experiencing a temporary financial hardship in which reductions are made to monthly required minimum payments for up to 12 months. Balances related to these programs are generally frozen, however, may be reopened upon successful exit of the program, in which account privileges may be restored.
Modifications to loans in the covered segment are similar in nature to that described above for non-covered loans, and the evaluation and determination of TDR status is similar, except that acquired loans restructured after acquisition are not considered TDRs for purposes of the Company’s accounting and disclosure if the loans evidenced credit deterioration as of the acquisition date and are accounted for in pools. Losses associated with the modification on covered loans, including the economic impact of interest rate reductions, are generally eligible for reimbursement under the loss sharing agreements.
