8. Product Warranty Obligations

The Company records a liability for product warranty obligations at the time of sale to a customer based upon historical warranty experience. The Company also records a liability for specific warranty matters when they become known and are reasonably estimable. Additionally, the Company sells extended warranty coverage for certain products. The sales of extended warranties are recorded as deferred revenue, which is recognized over the life of the contracts.

The following is a tabular reconciliation of the product warranty liability, excluding the deferred revenue related to extended warranty coverage:
