Past Due and Nonaccrual Loans
Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Generally, the recognition of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Consumer and other retail loans are typically charged-off no later than the time the loan is 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. All interest accrued for the current year, but not collected, for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Impaired Loans
A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Impairment is measured on a loan-by-loan basis for commercial, consumer and construction loans above a minimum dollar amount threshold by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are evaluated collectively for impairment. When the ultimate collectability of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied to principal. Once the recorded balance has been reduced to zero, future cash receipts are applied to interest income, to the extent any interest has been foregone, and then they are recorded as recoveries of any amounts previously charged-off. For impaired loans, a specific reserve is established to adjust the carrying value of the loan to its estimated net realizable value.
Loans accounted for under FASB Accounting Standards Codification Topic (“ASC”) 310-20, “Nonrefundable Fees and Other Cost” (“ASC 310-20”), and which are impaired loans recognized in conformity with ASC 310, “Receivables” (“ASC 310”), segregated by class, were as follows as of the dates presented:

Restructured Loans
Restructured loans are those for which concessions have been granted to the borrower due to a deterioration of the borrower’s financial condition and which are performing in accordance with the new terms. Such concessions may include reduction in interest rates or deferral of interest or principal payments. In evaluating whether to restructure a loan, management analyzes the long-term financial condition of the borrower, including guarantor and collateral support, to determine whether the proposed concessions will increase the likelihood of repayment of principal and interest.
The following tables illustrate the impact of modifications classified as restructured loans which were held on the Consolidated Balance Sheet at period end and are segregated by class for the periods presented.

Restructured loans not performing in accordance with their restructured terms that are either contractually 90 days or more past due or placed on nonaccrual status are reported as nonperforming loans. There was one restructured loan in the amount of $71 contractually 90 days past due or more and still accruing at June 30, 2017 and no restructured loans contractually 90 days past due or more and still accruing at June 30, 2016. The outstanding balance of restructured loans on nonaccrual status was $4,409 and $5,562 at June 30, 2017 and June 30, 2016, respectively.

Changes in the Company’s restructured loans are set forth in the table below:

The allocated allowance for loan losses attributable to restructured loans was $238 and $790 at June 30, 2017 and June 30, 2016, respectively. The Company had no remaining availability under commitments to lend additional funds on these restructured loans at June 30, 2017 and June 30, 2016, respectively.
Credit Quality
For commercial and commercial real estate loans, internal risk-rating grades are assigned by lending, credit administration or loan review personnel, based on an analysis of the financial and collateral strength and other credit attributes underlying each loan. Management analyzes the resulting ratings, as well as other external statistics and factors such as delinquency, to track the migration performance of the portfolio balances of these loans. Loan grades range between 1 and 9, with 1 being loans with the least credit risk. Loans that migrate toward the “Pass” grade (those with a risk rating between 1 and 4) or within the “Pass” grade generally have a lower risk of loss and therefore a lower risk factor applied to the loan balances. The “Watch” grade (those with a risk rating of 5) is utilized on a temporary basis for “Pass” grade loans where a significant adverse risk-modifying action is anticipated in the near term. Loans that migrate toward the “Substandard” grade (those with a risk rating between 6 and 9) generally have a higher risk of loss and therefore a higher risk factor applied to the related loan balances. The following table presents the Company’s loan portfolio by risk-rating grades as of the dates presented:
