Warranty liability rollforward

A warranty-liability rollforward explains why the assurance-warranty balance changed during the reporting period. It keeps obligations from prior sales, new provisions, revised estimates, and settled claims visible as separate movements.

Start with the assurance population

Exclude separately sold maintenance and other service promises. Their allocated transaction price follows Topic 606 and does not belong in the assurance liability. Also reconcile the opening balance to the prior period before adding current activity. An unexplained opening difference is an evidence problem, not a rollforward line.

Reconcile each movement

Use the following structure for a supplied assurance population:

Opening liability
+ provision for warranties issued in the current period
+ or - changes in estimates for warranties issued before the current period
- claims settled in cash or in kind
= ending liability

The current provision measures expected cost for current covered sales. An estimate revision reflects new evidence about obligations that were already recognized. Claims consume the liability through repairs, replacements, parts, labor, or cash. Claims do not measure current warranty expense.

For example, an opening liability of $54,000, a $72,000 current provision, a $6,000 upward revision, and $63,000 of claims produce a $69,000 ending liability. Current expense is $78,000, which is the provision plus the upward revision. The related calculation is checked in the connected lesson and task.

Connect the schedule to disclosure

ASC 460-10-50-8 requires the accounting policy and method used to determine the product-warranty liability. It also requires a tabular reconciliation showing the beginning balance, reductions for payments, accruals for current-period warranties, changes in accruals for earlier warranties, and the ending balance. The page's teaching schedule follows those categories; it does not establish that the illustrative amounts meet every disclosure requirement.

If an assurance obligation cannot be reasonably estimated, do not invent a rollforward amount. ASC 460-10-50-7 routes that condition to the related loss-contingency disclosures.

Follow the learning path

The assurance-warranty lesson develops the schedule and sensitivity cases. The Cedar Trail close connects the rollforward to journal entries. The warranty-rollforward task checks the expense, ending balance, and scope conclusion.

This page does not choose claim assumptions or decide warranty scope. Complete those steps before using the reconciliation.
