12. Guarantees

Product Warranty

Our products are generally sold with warranty periods that range from

12

to

36

months following sale or acceptance. The product warranty promises customers that delivered products are as specified in the contract (an “assurance-type warranty”). Therefore, we account for such product warranties under ASC

460,

and

not

as a separate performance obligation. Parts and labor are covered under the terms of the warranty agreement. The warranty provision is based on historical and projected experience by product and configuration.

Changes in accrued warranty were as follows (
