Description of standard product warranty Products purchased include a standard warranty that cannot be purchased separately. This allows customers to return defective products for repair or replacement within one year of sale.    
Description of extended product warranty The Company also sells an extended warranty for the same terms over three years. The extended 3-year warranty can be purchased separately from the product and therefore, must be classified as a service warranty. Since a warranty for the first year after sale is included and non-separable from all launcher purchases, the Company considers this extended warranty to represent a service obligation during the second and third years after sale.
