For the three and nine months ended September 30, 2019 and 2018, the amount of interest income recognized on impaired loans within the period that the loans were impaired were primarily related to loans modified in a troubled debt restructuring ("TDR") that were on accrual status. For the three and nine months ended September 30, 2019 and 2018, the amount of interest income recognized using a cash-based method of accounting during the period that the loans were impaired was not material.

The Company had $0.3 million and $0.7 million of residential mortgage loans collateralized by residential real estate property that were in the process of foreclosure at September 30, 2019 and December 31, 2018, respectively.

For all loan types, the Company determines delinquency status by considering the number of days full payments required by the contractual terms of the loan are past due. The following tables present by class, the aging of the recorded investment in past due loans and leases as of September 30, 2019 and December 31, 2018:

Concessions made to the original contractual terms of these loans consisted primarily of the deferral of interest and/or principal payments due to deterioration in the borrowers' financial condition. The principal balances on these TDRs had matured and/or were in default at the time of restructure, and we have no commitments to lend additional funds to any of these borrowers. There were $8.9 million of TDRs still accruing interest at September 30, 2019, none of which were more than 90 days delinquent. At December 31, 2018, there were $12.9 million of TDRs still accruing interest, none of which were more than 90 days delinquent.

Some loans modified in a TDR may already be on nonaccrual status and partial charge-offs may have already been taken against the outstanding loan balance. Thus, these loans have already been identified as impaired and have already been evaluated under the Company's allowance for loan and lease losses (the "Allowance") methodology. Loans that were not on nonaccrual status when modified in a TDR may have the financial effect of increasing the specific allowance associated with the loan. The loans modified in a TDR did not have a material effect on our provision for loan and lease losses (the "Provision") and the Allowance during the three and nine months ended September 30, 2019.

The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans and leases individually by classifying the loans and leases by credit risk. This analysis includes non-homogeneous loans and leases, such as commercial and commercial real estate loans. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings:

Special Mention. Loans and leases classified as special mention, while still adequately protected by the borrower's capital adequacy and payment capability, exhibit distinct weakening trends and/or elevated levels of exposure to external conditions. If left unchecked or uncorrected, these potential weaknesses may result in deteriorated prospects of repayment. These exposures require management's close attention so as to avoid becoming undue or unwarranted credit exposures.

Substandard. Loans and leases classified as substandard are inadequately protected by the borrower's current financial condition and payment capability or of the collateral pledged, if any. Loans and leases so classified have a well-defined weakness or weaknesses that jeopardize the orderly repayment of debt. They are characterized by the distinct possibility that the bank will sustain some loss if the deficiencies are not corrected.

Doubtful. Loans and leases classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or orderly repayment in full, on the basis of current existing facts, conditions and values, highly questionable and improbable. Possibility of loss is extremely high, but because of certain important and reasonably specific factors that may work to the advantage and strengthening of the exposure, its classification as an estimated loss is deferred until its more exact status may be determined.

Loss. Loans and leases classified as loss are considered to be non-collectible and of such little value that their continuance as bankable assets is not warranted. This does not mean the loan has absolutely no recovery value, but rather it is neither practical nor desirable to defer writing off the loan, even though partial recovery may be obtained in the future. Losses are taken in the period in which they surface as uncollectible.

Loans and leases not meeting the criteria above are considered to be pass-rated. The following table presents by class and credit indicator, the recorded investment in the Company's loans and leases as of September 30, 2019 and December 31, 2018:
