Will someone please share the FASB codification regarding the write off of finance charges receivable? Our customers signed agreements allowing us to charge finance charges on past due invoices, which should make the interest earned. However, we now want to write these finance charges off. How would I do that? Does the debit hit a bad debt expense that's disguised as an "Other Expense" (so that the interest income and bad debt expense would both hit as an "Other" item when adjusting operating income to net income) or would you simply reverse the interest revenue you recorded in the first place? Do we need an allowance for interest receivable we might not get?
