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. |  |  |
