(4) Past due balances of Receivables still accruing finance income represent the total balance held (principal plus accrued interest) with any payment amounts 30 days or more past the contractual payment due date.

The Company monitors the credit quality of Receivables as either performing or non-performing monthly. Non-performing Receivables represent loans for which the Company has ceased accruing finance income. Generally, when retail notes are approximately 120 days delinquent, accrual of finance income is suspended, the collateral is repossessed or the account is designated for litigation, and the estimated uncollectible amount, after charging the dealer's withholding account, if any, is written off to the allowance for credit losses. Revolving charge accounts are generally deemed to be uncollectible and written off to the allowance for credit losses when delinquency reaches 120 days. Generally, when a wholesale receivable becomes 60 days delinquent, the Company determines whether the accrual of finance income on interest-bearing wholesale receivables should be suspended, the collateral should be repossessed or the account should be designated for litigation, and the estimated uncollectible amount written off to the allowance for credit losses. Generally, when a financing lease account becomes 120 days delinquent, the accrual of lease revenue is suspended, the equipment is repossessed or the account is designated for litigation, and the estimated uncollectible amount, after charging the dealer's withholding account, if any, is written off to the allowance for credit losses. Finance income for non-performing Receivables is recognized on a cash basis. Accrual of finance income is generally resumed when the receivable becomes contractually current and collections are reasonably assured.

An age analysis of past due Receivables that are still accruing interest and non-performing Receivables was as follows (in millions of dollars):

Allowances for credit losses on Receivables are maintained in amounts considered to be appropriate in relation to the Receivables outstanding based on historical loss experience by product category, portfolio duration, delinquency trends, economic conditions, and credit risk quality.

Receivables are considered impaired when it is probable the Company will be unable to collect all amounts due according to the contractual terms. Receivables reviewed for impairment generally include those that are either past due, or have provided bankruptcy notification, or require significant collection efforts. Receivables that are impaired are generally classified as non‑performing.

A troubled debt restructuring is generally the modification of debt in which a creditor grants a concession it would not otherwise consider to a debtor that is experiencing financial difficulties. These modifications may include a reduction of the stated interest rate, an extension of the maturity dates, a reduction of the face amount or maturity amount of the debt, or a reduction of accrued interest. During the first nine months of 2018, the Company identified 286 Receivable contracts, primarily retail notes, as troubled debt restructurings with aggregate balances of $16.2 million pre‑modification and $15.4 million post‑modification. During the first nine months of 2017, there were 290 Receivable contracts, primarily retail notes, with aggregate balances of $7.7 million pre‑modification and $6.5 million post‑modification. During these same periods, there were no significant troubled debt restructurings that subsequently defaulted and were written off. At July 29, 2018, the Company had no commitments to lend additional funds to borrowers whose accounts were modified in troubled debt restructurings.
