| (a) | Included within machinery and equipment were assets under capital leases with costs of $1,069 and $533 and associated accumulated depreciation of $258 and $222 as of July 1, 2018 and December 31, 2017, respectively. The related depreciation expense for the three months ended July 1, 2018 and July 2, 2017 was $21 and $55, respectively. The related depreciation expense for the six months ended July 1, 2018 and July 2, 2017 was $36 and $133, respectively. | | | | | (b) | Included within computer hardware and software are assets under capital leases with costs of $91 and $Nil as at July 1, 2018 and December
31, 2017 and associated accumulated depreciation of $5 and $Nil as at July 1, 2018 and December
31, 2017, respectively. The related depreciation expense for the three months ended July 1, 2018 and July 2, 2017 was $5 and $Nil, respectively. The related depreciation expense for the six months ended July 1, 2018 and July 2, 2017 was $5 and $3, respectively. | | | | | (c) | In accordance with ASC 360 -10, the Company is required to evaluate for impairment when events or changes in circumstances indicate that the carrying value of such assets may
not be recoverable. Upon the occurrence of a triggering event, the Company assesses whether the estimated undiscounted cash flows expected from the use of the asset and the residual value from the ultimate disposal of the asset exceeds the carrying value. As at July 1, 2018, the Company identified that operating results for its China segment asset group did not meet forecasted results for the six months ended July 1, 2018, which was considered a triggering event related to its China segment asset group. The net carrying amount of the China asset group is $1,161. The Company estimated undiscounted cash flows and determined a recoverable amount of $1,112 in excess of the net carrying value, therefore no impairment loss was recorded in 2018. The key assumptions included in these cash flows are projected revenue based on management’s forecast and corresponding margins. The estimate of undiscounted cash flows are sensitive to these key assumptions, for instance, if our revenue projections are lower by 10%, the recoverable amount in excess of the carrying amount would be reduced to $775. As such, the Company continues to monitor for impairment triggers each quarter, which may result in future impairments in this asset group. | | | Interim Consolidated financial statement details cont’d | | | | | | | | | | Customer related | | $ | 1,477 | | | $ | 936 | | | Payroll | | | 2,724 | | | | 2,485 | | | Professional services | | | 307 | | | | 328 | | | Restructuring | | | 137 | | | | 109 | | | Vendor related | | | 696 | | | | 493 | | | Other | | | 847 | | | | 526 | | | Total | | $ | 6,188 | | | $ | 4,877 | | Interim consolidated statements of operations and comprehensive loss | | | | | | | | | | | | | | | | | | | | | | | Revolving credit facility | | $ | 224 | | | $ | 87 | | | $ | 400 | | | $ | 142 | | | Long-term debt | | | 107 | | | | 117 | | | | 214 | | | | 226 | | | Equipment facility | | | 14 | | | | — | | | | 14 | | | | — | | | Amortization of deferred financing fees | | | 11 | | | | 7 | | | | 21 | | | | 11 | | | Obligations under capital leases | | | 47 | | | | 6 | | | | 61 | | | | 17 | | | Interest expense | | $ | 403 | | | $ | 217 | | | $ | 710 | | | $ | 396 | |
