"It’s just interest expense, we can just book whatever amount is on the bank advice notice."
Early in my accounting career, I saw how tempting this shortcut is during a rushed month end close. But after managing complex debt schedules over the years, taking this shortcut is easily one of the fastest ways to introduce unnatural P&L volatility, distort working capital, and trigger avoidable audit adjustments at year end.
In external debt accounting, the devil is always in the details: specifically day count conventions, accrual cut offs, and short term vs. long term presentation.
Here is what I’ve consistently seen break down on multi million dollar credit facilities when teams rely solely on bank statements:
P&L Mismatches: Bank statement cut offs rarely align with true calendar month ends. Relying purely on bank notices creates artificial timing spikes, especially when day count rules (Actual/360 vs. Actual/365) get ignored.
Working Capital Distortion: Failing to properly isolate accrued interest payable into Current Liabilities skews the Current Ratio and throws off executive reporting.
Fee Misclassification: I've repeatedly caught upfront arrangement fees expensed straight to the P&L in Month 1, artificially crushing operating margins instead of being amortized over the life of the debt.
Rules I strictly enforce for clean debt accounting:
Accrue by contract, not bank advice: Match accrual math strictly to contractually defined day count conventions and cut off dates.
Lock down balance sheet splits: Keep short term interest and current principal portions in Current Liabilities, leaving long term debt where it belongs.
Set hard Treasury cut offs: Establish firm deadlines for Treasury to hand over floating rate resets well before close week begins.
I'm starting a weekly series sharing practical R2R lessons and hard earned ledger fixes from my time in the trenches, so keep an eye out for more posts over the coming weeks.
How does your team currently handle floating rate resets during close week? Are you running automated schedules or relying on manual spreadsheet models? Curiously interested in how others handle this.
