The loans and leases portfolio categories are comprised of the following:
Commercial real estate includes both owner-occupied and non-owner-occupied loans secured by commercial properties;
Commercial and industrial includes loans to businesses that are not secured by real estate;
Commercial leases consist of leases for new or used equipment;
Other is comprised primarily of credit cards and mezzanine loans;
Direct installment is comprised of fixed-rate, closed-end consumer loans for personal, family or household use, such as home equity loans and automobile loans;
Residential mortgages consist of conventional and jumbo mortgage loans for 1-4 family properties;
Indirect installment is comprised of loans originated by approved third parties and underwritten by us, primarily automobile loans; and
Consumer lines of credit include home equity lines of credit and consumer lines of credit that are either unsecured or secured by collateral other than home equity.
The loans and leases portfolio consists principally of loans to individuals and small- and medium-sized businesses within our primary market areas of Pennsylvania, eastern Ohio, Maryland, North Carolina, South Carolina and northern West Virginia.

Acquired Loans
All acquired loans were initially recorded at fair value at the acquisition date. Refer to the Acquired Loans section in Note 1 of our 2017 Annual Report on Form 10-K for a discussion of ASC 310-20 and ASC 310-30 loans. The outstanding balance and the carrying amount of acquired loans included in the Consolidated Balance Sheets are as follows:

The outstanding balance is the undiscounted sum of all amounts owed under the loan, including amounts deemed principal, interest, fees, penalties and other, whether or not currently due and whether or not any such amounts have been written or charged-off.
The carrying amount of purchased credit impaired loans included in the table above totaled $1.7 million at June 30, 2018 and $1.9 million at December 31, 2017, representing 0.04% and 0.03%, respectively, of the carrying amount of total acquired loans as of each date.
The following table provides changes in accretable yield for all acquired loans accounted for under ASC 310-30. Loans accounted for under ASC 310-20 are not included in this table.

Cash flows expected to be collected on acquired loans are estimated quarterly by incorporating several key assumptions similar to the initial estimate of fair value. These key assumptions include probability of default and the amount of actual prepayments after the acquisition date. Prepayments affect the estimated life of the loans and could change the amount of interest income, and possibly principal expected to be collected. In reforecasting future estimated cash flows, credit loss expectations are adjusted as necessary. Improved cash flow expectations for loans or pools are recorded first as a reversal of previously recorded impairment, if any, and then as an increase in prospective yield when all previously recorded impairment has been recaptured. Decreases in expected cash flows are recognized as impairment through a charge to the provision for credit losses and credit to the allowance for credit losses.
During the six months ended June 30, 2018, there was an overall improvement in cash flow expectations which resulted in a net reclassification of $129.0 million from the non-accretable difference to accretable yield. This reclassification was $40.3 million for the six months ended June 30, 2017. The reclassification from the non-accretable difference to the accretable yield results in prospective yield adjustments on the loan pools and was also positively impacted by the sale of $56.5 million of acquired residential mortgage loans in the second quarter of 2018.
Credit Quality
Management monitors the credit quality of our loan portfolio using several performance measures to do so based on payment activity and borrower performance.
Non-performing loans include non-accrual loans and non-performing TDRs. Past due loans are reviewed on a monthly basis to identify loans for non-accrual status. We place originated loans on non-accrual status and discontinue interest accruals on originated loans generally when principal or interest is due and has remained unpaid for a certain number of days or when the full amount of principal and interest is due and has remained unpaid for a certain number of days, unless the loan is both well secured and in the process of collection. Commercial loans and leases are placed on non-accrual at 90 days, installment loans are placed on non-accrual at 120 days and residential mortgages and consumer lines of credit are generally placed on non-accrual at 180 days, though we may place a loan on non-accrual prior to these past due thresholds as warranted. When a loan is placed on non-accrual status, all unpaid accrued interest is reversed. Non-accrual loans may not be restored to accrual status until all delinquent principal and interest have been paid and the ultimate ability to collect the remaining principal and interest is reasonably assured. The majority of TDRs are loans in which we have granted a concession on the interest rate or the original repayment terms due to the borrower’s financial distress.

The carrying value of residential other real estate owned held as a result of obtaining physical possession upon completion of a foreclosure or through completion of a deed in lieu of foreclosure amounted to $6.0 million at June 30, 2018 and $3.6 million at December 31, 2017. The recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process at June 30, 2018 and December 31, 2017 totaled $12.5 million and $15.2 million, respectively.

(1)
Past due information for acquired loans is based on the contractual balance outstanding at June 30, 2018 and December 31, 2017.
(2)
Acquired loans are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if we can reasonably estimate the timing and amount of expected cash flows on such loans. In these instances, we do not consider acquired contractually delinquent loans to be non-accrual or non-performing and continue to recognize interest income on these loans using the accretion method. Acquired loans are considered non-accrual or non-performing when, due to credit deterioration or other factors, we determine we are no longer able to reasonably estimate the timing and amount of expected cash flows on such loans. We do not recognize interest income on acquired loans considered non-accrual or non-performing.
(3)
Approximately $28.5 million of acquired past-due or non-accrual loans were sold during the second quarter of 2018.
(4)
Approximately $14.7 million of originated past-due or non-accrual loans were sold during the second quarter of 2018.
We utilize the following categories to monitor credit quality within our commercial loan and lease portfolio:

Rating
Category
Definition
Pass
in general, the condition of the borrower and the performance of the loan is satisfactory or better
 
 
Special Mention
in general, the condition of the borrower has deteriorated, requiring an increased level of monitoring
 
 
Substandard
in general, the condition of the borrower has significantly deteriorated and the performance of the loan could further deteriorate if deficiencies are not corrected
 
 
Doubtful
in general, the condition of the borrower has significantly deteriorated and the collection in full of both principal and interest is highly questionable or improbable
The use of these internally assigned credit quality categories within the commercial loan and lease portfolio permits management’s use of transition matrices to estimate a quantitative portion of credit risk. Our internal credit risk grading system is based on past experiences with similarly graded loans and leases and conforms with regulatory categories. In general, loan and lease risk ratings within each category are reviewed on an ongoing basis according to our policy for each class of loans and leases. Each quarter, management analyzes the resulting ratings, as well as other external statistics and factors such as delinquency, to track the migration performance of the commercial loan and lease portfolio. Loans and leases within the Pass credit category or that migrate toward the Pass credit category generally have a lower risk of loss compared to loans and leases that migrate toward the Substandard or Doubtful credit categories. Accordingly, management applies higher risk factors to Substandard and Doubtful credit categories.
The following tables present a summary of our commercial loans and leases by credit quality category, segregated by loans and leases originated and loans acquired:

Credit quality information for acquired loans is based on the contractual balance outstanding at June 30, 2018 and December 31, 2017.
We use delinquency transition matrices within the consumer and other loan classes to enable management to estimate a quantitative portion of credit risk. Each month, management analyzes payment and volume activity, Fair Isaac Corporation (FICO) scores and other external factors such as unemployment, to determine how consumer loans are performing.

Loans and leases are designated as impaired when, in the opinion of management, based on current information and events, the collection of principal and interest in accordance with the loan and lease contract is doubtful. Typically, we do not consider loans and leases for impairment unless a sustained period of delinquency (i.e., 90-plus days) is noted or there are subsequent events that impact repayment probability (i.e., negative financial trends, bankruptcy filings, imminent foreclosure proceedings, etc.). Impairment is evaluated in the aggregate for consumer installment loans, residential mortgages, consumer lines of credit and commercial loan and lease relationships less than $0.5 million based on loan and lease segment loss given default. For commercial loan and lease relationships greater than or equal to $0.5 million, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using a market interest rate or at the fair value of collateral if repayment is expected solely from the collateral. Consistent with our existing method of income recognition for loans and leases, interest income on impaired loans, except those classified as non-accrual, is recognized using the accrual method. Impaired loans, or portions thereof, are charged off when deemed uncollectible.

Troubled Debt Restructurings
TDRs are loans whose contractual terms have been modified in a manner that grants a concession to a borrower experiencing financial difficulties. TDRs typically result from loss mitigation activities and could include the extension of a maturity date, interest rate reduction, principal forgiveness, deferral or decrease in payments for a period of time and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral.

TDRs that are accruing and performing include loans that met the criteria for non-accrual of interest prior to restructuring for which we can reasonably estimate the timing and amount of the expected cash flows on such loans and for which we expect to fully collect the new carrying value of the loans. During the six months ended June 30, 2018, we returned to performing status $2.2 million in restructured residential mortgage loans that have consistently met their modified obligations for more than six months. TDRs that are accruing and non-performing are comprised of consumer loans that have not demonstrated a consistent repayment pattern on the modified terms for more than six months, however it is expected that we will collect all future principal and interest payments. TDRs that are on non-accrual are not placed on accruing status until all delinquent principal and interest have been paid and the ultimate collectability of the remaining principal and interest is reasonably assured. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, and may result in potential incremental losses which are factored into the allowance for credit losses.
Excluding purchased impaired loans, commercial loans over $0.5 million whose terms have been modified in a TDR are generally placed on non-accrual, individually analyzed and measured for estimated impairment based on the fair value of the underlying collateral. Our allowance for credit losses included specific reserves for commercial TDRs and pooled reserves for individually impaired loans under $0.5 million based on loan segment loss given default. Upon default, the amount of the recorded investment in the TDR in excess of the fair value of the collateral, less estimated selling costs, is generally considered a confirmed loss and is charged-off against the allowance for credit losses. The reserve for commercial TDRs included in the allowance for credit losses is presented in the following table:

All other classes of loans, which are primarily secured by residential properties, whose terms have been modified in a TDR are pooled and measured for estimated impairment based on the expected net present value of the estimated future cash flows of the pool. Our allowance for credit losses included pooled reserves for these classes of loans of $4.2 million for June 30, 2018 and $4.0 million for December 31, 2017. Upon default of an individual loan, our charge-off policy is followed accordingly for that class of loan.
