All PI loans are considered to be accruing for all periods presented, in accordance with ASC 310-30.

During the twelve months ended December 31, 2014, we purchased $19.7 million of performing residential mortgage loans, including premiums of $0.3 million. During the twelve months ended December 31, 2013, we purchased $157.6 million of performing residential mortgage loans, including premiums of $1.3 million. These loan purchases are accounted for as PC loans.

Risk Grades

The risk-grade categories presented in the following table, which are standard categories used by the bank regulators, are:

Pass - Loans categorized as Pass are higher quality loans that have adequate sources of repayment and little risk of collection.

Special Mention - A Special Mention loan has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution's credit position at some future date. Special Mention loans are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.

Substandard - A Substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of Substandard loans, does not have to exist in individual assets classified Substandard.

Doubtful - A loan classified as Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors, which may work to the advantage of strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans.

Loans categorized as Special Mention or worse are considered Criticized. Loans categorized as Substandard or Doubtful are considered Classified. Purchased loans acquired in the Merger are recorded at estimated fair value on the date of acquisition without the carryover of related ALL. The table below includes $27.0 million and $40.5 million in Granite Purchased Loans categorized as Substandard or Doubtful at December 31, 2014 and December 31, 2013, respectively.

The following table presents loans held for investment balances by risk grade as of December 31, 2014:

Loans included in the preceding loan composition table are net of participations sold. Loans are increased by net loan premiums and deferred loan costs of $3.2 million at December 31, 2014 and $3.6 million at December 31, 2013.

At December 31, 2014 and 2013, loans held for sale consisted of originated residential mortgage loans held for sale at the lower of cost or fair market value.

Loans serviced for others are not included in the consolidated balance sheet. The unpaid principal balance of loans serviced for others amounted to $235.0 million at December 31, 2014 and $190.2 million at December 31, 2013.

Loans Pledged

To borrow from the FHLB, members must pledge collateral to secure advances and letters of credit. Acceptable collateral includes, among other types of collateral, a variety of residential, multifamily, home equity lines and second mortgages, and commercial loans. Investment securities of $124.6 million and $24.1 million and gross loans of $127.2 million and $169.5 million were pledged to collateralize FHLB advances and letters of credit at December 31, 2014 and December 31, 2013, respectively, of which there was $130.8 million and $31.8 million of credit availability for borrowing, respectively. At December 31, 2014, $48.6 million of securities and $5.3 million of loans were pledged to collateralize potential borrowings from the Federal Reserve Discount Window, of which $52.0 million was available as borrowing capacity. We could also access $202.5 million of additional borrowings from the FHLB under credit lines by pledging additional collateral.

Nonaccruing and Impaired Loans

Interest income on loans is calculated by using the interest method based on the daily outstanding balance. The recognition of interest income is discontinued when, in management's opinion, the collection of all or a portion of interest becomes doubtful. Loans are returned to accrual status when the factors indicating doubtful collectability cease to exist and the loan has performed in accordance with its terms for a demonstrated period of time. The past due status of loans is based on the contractual payment terms. Had nonaccruing loans been on accruing status, interest income would have been higher by $3.7 million and $4.7 million for the twelve months ended December 31, 2014 and December 31, 2013, respectively. At December 31, 2014 and December 31, 2013, COB had certain impaired loans of $25.3 million and $35.2 million, respectively, which were on nonaccruing interest status.

Impaired loans also include loans for which we may elect to grant a concession, providing terms more favorable than those prevalent in the market (e.g., rate, amortization term), and formally restructure due to the weakening credit status of a borrower. Restructuring is designed to facilitate a repayment plan that minimizes the potential losses that we otherwise may have to incur. If these impaired loans are on nonaccruing status as of the date of restructuring, the loans are included in nonperforming loans. Nonaccruing restructured loans will remain as nonaccruing until the borrower can demonstrate adherence to the restructured terms for a period of no less than six months and when it is otherwise determined that continued adherence is reasonably assured. Some restructured loans continue as accruing loans after restructuring if the borrower is not past due at the time of restructuring, adequate collateral valuations support the restructured loans, and the cash flows of the underlying business appear adequate to support the restructured debt service. Not included in nonaccruing loans are loans that have been restructured that were performing as of the restructure date. At December 31, 2014, there was $19.4 million in restructured loans, of which $14.1 million were accruing and in a performing status. At December 31, 2013, there was $18.1 million in restructured loans, of which $12.1 million were accruing and in a performing status.

Sale of Problem Loans

During 2012, we sold loans to third party buyers in order to reduce our problem loan exposure. These loans were transferred to loans held for sale at the time we received a signed contract for the purchase of the loans. Prior to transferring these loans to loans held for sale, the loans were marked down to the contract price less associated selling costs. All transactions were conducted at arm's length and loans were sold without recourse.

The following table presents sold loans by portfolio segment for the periods indicated below:

Granite Purchased Loans

Granite Purchased Loans include PI loans and PC loans. PC loans include performing revolving consumer and commercial loans on October 21, 2011, the acquisition date.

PI loans are segregated into pools and recorded at estimated fair value on the date of acquisition without the carryover of the related ALL. PI loans are accounted for under ASC 310-30 when the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition we will not collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the date of acquisition may include statistics such as past due status, nonaccrual status and risk grade. PI loans generally meet our definition for nonaccrual status; however, even if the borrower is not currently making payments, we will classify loans as accruing if we can reasonably estimate the amount and timing of future cash flows. All Granite Purchased PI loans are presented on an accruing basis. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference.

Periodically, we estimate the expected cash flows for each pool of the PI loans and evaluate whether the expected cash flows for each pool have changed from prior estimates. Decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges, or reclassification from nonaccretable difference to accretable yield with a positive impact on future interest income. Excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows.

We have elected to account for the Granite Purchased PI loans under ASC 310-30 and the Granite Purchased PC loans under ASC 310-20.

At December 31, 2014, and December 31, 2013, our financial statements reflected a PI loan ALL of $3.2 million and $5.6 million, respectively, and an ALL for PC loans of $0.3 million and $0.3 million, respectively.

During the twelve months ended December 31, 2014, we modified 25 loans that were considered to be troubled debt restructurings. We extended the terms for 8 of these loans and modified the remaining 17 loans by both extending the term and modifying the interest rate. During the twelve months ended December 31, 2013, we modified 19 loans that were considered to be troubled debt restructurings. We extended the terms for 3 of these loans, modified the interest rate for 2 of these loans, and modified the remaining 14 loans in both ways.

There were no loans restructured in the twelve months prior to December 31, 2014 that went into default during the year ended December 31, 2014. There were also no loans restructured in the twelve months prior to December 31, 2013 that went into default during the year ended December 31, 2013.

In the determination of the ALL, management considers troubled debt restructurings and any subsequent defaults in these restructurings as impaired loans. The amount of the impairment is measured using the present value of expected future cash flows discounted at the loan's initial effective interest rate, the observable market price of the loan, or the fair value of the collateral if the loan is collateral dependent.

Unfunded Commitments

The reserve for unfunded commitments, which is included in other liabilities, is calculated by estimating the amount of additional funding on the commitment and multiplying that amount by the historical loss rate (including Q&E factors). The following describes our method for determining the estimated additional funding by commitment type:


•	Straight Lines of Credit - Unfunded balance of line of credit (100% utilization)


•	Revolving Lines of Credit - Average Utilization (for the last 12 months) less Current Utilization


•	Letters of Credit - 10% utilization

The reserve for unfunded commitments was $0.8 million as of December 31, 2014 and $0.5 million at December 31, 2013.
