For all classes, loans are placed on non-accrual status when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement or when principal and interest is 90 days or more past due unless the loan is both well secured and in the process of collection (in which case the loan may continue to accrue interest in spite of its past due status). A loan is "well secured" if it is secured (1) by collateral in the form of liens on or pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt (including accrued interest) in full, or (2) by the guarantee of a financially responsible party. A loan is "in the process of collection" if collection of the loan is proceeding in due course either (1) through legal action, including judgment enforcement procedures, or, (2) in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status in the near future. Cash payments received on non-accrual loans, which are included in impaired loans, are applied to reduce the loan's principal balance until the remaining principal balance is deemed collectible, after which interest is recognized when collected. As a general rule, a loan may be restored to accrual status when payments are current for a substantial period of time, generally six months, and repayment of the remaining contractual amounts is expected or when it otherwise becomes well secured and in the process of collection. Information on nonaccrual loans as of September 30, 2017 and 2016 and at December 31, 2016 is presented in the following table:

Impaired loans include troubled debt restructured ("TDR") and loans placed on non-accrual. These loans are measured at the present value of expected future cash flows discounted at the loan's effective interest rate or at the fair value of the collateral if the loan is collateral dependent. If the measure of an impaired loan is lower than the recorded investment in the loan and estimated selling costs, a specific reserve is established for the difference, or, in certain situations, if the measure of an impaired loan is lower than the recorded investment in the loan and estimated selling costs, the difference is written off. A breakdown of impaired loans by class of financing receivable as of and for the period ended September 30, 2017 is presented in the following table:

Troubled Debt Restructured A "TDR" constitutes a restructuring of debt if the Company, for economic or legal reasons related to the borrower's financial difficulties, grants a concession to the borrower that it would not otherwise consider. To determine whether or not a loan should be classified as a TDR, Management evaluates a loan based upon the following criteria:
• | The borrower demonstrates financial difficulty; common indicators include past due status with bank obligations, substandard credit bureau reports, or an inability to refinance with another lender, and
• | The Company has granted a concession; common concession types include maturity date extension, interest rate adjustments to below market pricing, and deferment of payments.
As of September 30, 2017, the Company had 67 loans with a balance of $19,760,000 that have been classified as TDRs. This compares to 71 loans with a balance of $21,526,000 and 75 loans with a balance of $22,025,000 classified as TDRs as of December 31, 2016 and September 30, 2016, respectively. The impairment carried as a specific reserve in the allowance for loan losses is calculated by present valuing the expected cash flows on the loan at the original interest rate, or, for collateral-dependent loans, using the fair value of the collateral less costs to sell. The following table shows TDRs by class and the specific reserve as of September 30, 2017:
