Commitments and Contingencies Disclosure [Abstract] |
Warranty Accrual | Warranty Accrual The Company provides a warranty against all substantial defects in material and workmanship. In 2005 the Company extended its standard warranty from five years to 10 years. Effective February 1, 2014 the Company modified its warranty to a limited lifetime warranty. The new warranty effective February 1, 2014 is not anticipated to have a significant effect on warranty expense. The Company’s warranty is not a guarantee of service life, which depends upon events outside the Company’s control and may be different from the warranty period. The Company accrues an estimate of its exposure to warranty claims based upon both product sales data and an analysis of actual warranty claims incurred. The following is a summary of the Company’s warranty-claim activity for the three months and six months ended July 31, 2014 and 2013.
