Interim to Year-End Rollforward Calculator (AU-C 330 Remaining Period)

Does it tie out, and if not, where is the difference?

Roll a balance tested at an interim date to period end with the activity in the remaining period, and size that activity against the year-end balance.

How this was worked out
Work shownrecomputed as you type
Rolled-forward = interim balance + additions - reductions
Break = recorded year end - rolled-forward
Gross activity = additions + reductions

The formulas

  • Rolled-forward = interim balance + additions - reductions
  • Break = recorded year end - rolled-forward
  • Gross activity = additions + reductions

How it works

AU-C 330 paragraph .23 requires that, when substantive procedures are performed at an interim date, the auditor covers the remaining period with further substantive procedures, alone or combined with tests of controls, that give a reasonable basis for extending the interim conclusions to period end.

The rollforward proves the arithmetic. The size of the remaining activity says how much work it needs: activity that is large against the year-end balance or performance materiality needs tests of details, not just an analytic. Paragraph .A66 lists predictability of the balance and cutoff procedures as factors in that choice.

Common questions

What if I found misstatements at interim?

If they were not expected, AU-C 330 .24 requires you to evaluate whether the risk assessment and the planned procedures for the remaining period need to change.

Can I use only analytics for the rollforward?

When the balance is predictable and the entity's period-end analysis and cutoff are reliable, per AU-C 330 .A66.

Should the activity tie to other accounts?

Yes. Additions to receivables tie to sales, reductions to cash receipts and credits.
