The Company’s loans are mostly to customers within Oklahoma and over 60% of the loans are secured by real estate. Credit risk on loans is managed through limits on amounts loaned to individual borrowers, underwriting standards and loan monitoring procedures. The amounts and types of collateral obtained, if any, to secure loans are based upon the Company’s underwriting standards and management’s credit evaluation. Collateral varies, but may include real estate, equipment, accounts receivable, inventory, livestock and securities. The Company’s interest in collateral is secured through filing mortgages and liens, and in some cases, by possession of the collateral. Accounting policies related to appraisals, nonaccruals and charge-offs are disclosed in Footnote (1) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Nonperforming and Restructured Assets Nonaccrual loans, accruing loans past due 90 days or more, and restructured loans are shown in the table below. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $978,000 for the six months ended June 30, 2013 and approximately $654,000 for the six months ended June 30, 2012. At June 30, 2013, troubled debt restructurings consisted primarily of one loan restructured to defer principal payments. The loan was evaluated by management and determined to be well collateralized. Additionally, none of the concessions granted involved a principal reduction or a change from the current market rate of interest. The collateral value will be monitored periodically to evaluate possible impairment. The Company charges interest on principal balances outstanding during deferral periods. As a result, the current and future financial effects of the recorded balance of loans considered to be restructured were not considered to be material. The following is a summary of nonperforming and restructured assets:
|  | June 30, |  |  | December 31, |  |  | June 30, |

The following table is a summary of amounts included in nonaccrual loans, segregated by class of loans. Residential real estate refers to one-to-four family real estate.

Impaired Loans Loans are considered impaired when, based on current information and events, it is probable the Company will be unable to collect the full amount of scheduled principal and interest payments in accordance with the original contractual terms of the loan agreement. If a loan is impaired, a specific valuation allowance may be allocated, if necessary, so that the loan is reported net at the present value of future cash flows using the loan’s existing rate or the fair value of collateral if repayment is expected solely from the collateral. The following table presents impaired loans, segregated by class of loans. No material amount of interest income was recognized on impaired loans subsequent to their classification as impaired.

Credit Risk Monitoring and Loan Grading The Company considers various factors to monitor the risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical loan loss experience, and economic conditions. Loans are subject to an internal risk grading system which indicates the risk and acceptability of that loan. The loan grades used by the Company are for internal risk identification purposes and do not directly correlate to regulatory classification categories or any financial reporting definitions. The general characteristics of the risk grades are disclosed in Footnote (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The following table presents internal loan grading by class of loans:
