The cost and accumulated depreciation of assets retired or sold are removed from the respective accounts and any gain or loss is recognized in operations. The estimated useful lives of fixed assets are as follows:Computer equipment3 yearsMachinery and equipment5-7 yearsFurniture and fixtures5 yearsLeasehold improvementsEarlier of life of improvement or lease                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                |
