Extended Warranties

Deferred revenue represents the purchase of extended warranties by the Company's customers. The Company recognizes revenue from an extended warranty on the straight-line method over the life of the extended warranty, which is typically 12 to 15 months beyond the standard 12 month warranty. The Company classifies deferred revenue under other accrued liabilities in its consolidated balance sheets. The Company currently has $0.5 million of deferred revenue related to extended warranties.
