There were no business acquisitions made by the Company during fiscal years 2017 and 2016. Impairment - Goodwill and Long-lived Assets The Company’s impairment review process is completed during the fourth quarter of each year, or whenever events or circumstances occur that indicate that an impairment may have occurred. The goodwill impairment assessment involves three tests, Step 0, Step 1 and Step 2. The Company performs a Step 0 test, which involves an initial qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing the qualitative factors, the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test is necessary. Otherwise, no further testing is necessary. The Company completed its annual goodwill impairment assessment during the fourth quarter of 2018 by first performing a Step 0 qualitative assessment. As part of this assessment, the Company considered the trading value of the Company's stock, the industry trends, and the Company's sales forecast and products plans. The Company concluded that it was more likely than not that the fair value was more than the carrying values of the Company's reporting unit and therefore did not proceed to the Step 1 goodwill impairment test. The process of evaluating the potential impairment of long-lived assets is highly subjective and requires significant judgment. In estimating the fair value of these assets, the Company made estimates and judgments about future revenues and cash flows. The Company’s forecasts were based on assumptions that are consistent with the plans and estimates the Company is using to manage its business. Changes in these estimates could change the Company’s conclusion regarding impairment of the long-lived assets and potentially result in future impairment charges for all or a portion of their balance at December 29, 2018. The Company did not record any impairment charges related to goodwill in fiscal year 2018. The Company assesses if there have been triggers that may require it to evaluate the reasonableness of the remaining estimated useful lives of its intangible assets. No such triggers were identified during fiscal year 2018. Intangible assets are recorded at cost, less accumulated amortization. The Company recorded $23.5 million of intangible assets in conjunction with its acquisition of 4D in 2018 (See Note 3 – Acquisition). Intangible assets as of December 29, 2018 and December 30, 2017 consisted of the following (in thousands):
|  | December 29, 2018 |
|  | Adjusted cost |  |  | Accumulated amortization |  |  | Net carrying amount |
Developed technology |  | $ | 35,954 |  |  | $ | (16,532 | ) |  | $ | 19,422 |
Customer relationships |  |  | 6,531 |  |  |  | (1,519 | ) |  |  | 5,012 |
In-Process research and development |  |  | 1,400 |  |  |  | — |  |  |  | 1,400 |

The amortization of finite-lived intangibles is computed using the straight-line method. Estimated lives of finite-lived intangibles range from two to fifteen years. Total amortization expense for the fiscal years ended December 29, 2018, December 30, 2017 and December 31, 2016, was $0.4 million, $0.2 million and $1.5 million, respectively. There were no impairment charges related to intangible assets recorded during either the year ended December 29, 2018 or December 30, 2017. During 2018, the Company retired $16.1million of intangible assets that had been fully amortized for both book and tax purposes that were deemed to have no future utility to the Company. The estimated future amortization expense of finite intangible assets as of December 29, 2018, is as follows (in thousands):
Fiscal Years |  | Amounts |
2019 |  |  | 2,997 |
2020 |  |  | 2,905 |
2021 |  |  | 2,905 |
2022 |  |  | 2,905 |
2023 |  |  | 2,905 |
Thereafter |  |  | 11,309 |
Total future amortization expense |  |  | 25,926 |
In-Process research and development of $1.4 million acquired in the 4D acquisition has been omitted from the above table as its estimated useful life is indeterminant at December 29, 2018. It will be tested for impairment, along with Goodwill, until its estimated useful life becomes finite.
