The formulas
- Closing allowance = opening + provision - write-offs + recoveries
- Break = ledger closing - rolled-forward closing
- Look-back = write-offs / opening allowance
How it works
A rollforward proves the allowance moved only through provision, write-offs and recoveries. A break means an entry hit the allowance from another account, such as a direct reclass or a write-off booked to expense.
The look-back compares this year's write-offs with the allowance that existed for them at the start. Write-offs well above the opening allowance suggest the prior estimate was low, which bears on the current estimate under AU-C 540.

Common questions
Should write-offs include accounts from this year's sales?
Yes, they reduce the allowance whenever written off. For the look-back, separate write-offs of accounts that existed at the start of the year if you can.
Does this work for a CECL allowance?
Yes. The movement logic is the same; the provision is the credit loss expense.
Where do recoveries go?
Back into the allowance under most policies. If your entity credits recoveries to income, enter zero here.
