Product Warranties Disclosures [Abstract] |
Product Warranty | Product Warranty The Company’s products carry limited warranties that typically range from one to two years and vary by product. The warranty period begins on the date of retail purchase or lease by the original purchaser. The Company accrues estimated product warranty costs at the time of sale and any additional amounts are recorded when such costs are probable and can be reasonably estimated. Factors that affect the Company’s warranty liability include the number of units sold or leased, historical and anticipated rates of warranty repairs and the cost per repair. Warranty and related costs are reflected within sales, marketing and support in the accompanying statements of operations. As of September 30, 2013 and December 31, 2012, the Company had accrued product warranty costs of $1,010 and $814, respectively. The following table summarizes product warranty activity during 2013 and 2012:
