As summarized in Note 3, “Acquisition,” the Company completed its acquisition of Voxtel, Inc. during the nine-month period ended December 25, 2020. The Company paid an amount of $35,081 to acquire Voxtel, which represents its fair value on that date. Any excess of the Acquisition consideration over the fair value of the assets acquired and liabilities assumed was allocated to goodwill, which amounted to $18,803. As a result of the Acquisition, the Company recorded finite-life intangible assets of $13,600, the types and lives of which are detailed in the above-referenced financial note. In addition, as a result of the Acquisition, the Company recorded indefinite-life intangible assets of $2,400.

Intangible assets amortization expense was $926 and $2,310 for the three- and nine-month periods ended December 25, 2020, respectively, and $422 and $1,267 for the three- and nine-month periods ended December 27, 2019, respectively. The majority of the Company’s intangible assets are related to patents as noted above. The Company capitalizes external legal costs incurred in the defense of its patents when it believes that a significant, discernible increase in value will result from the defense and a successful outcome of the legal action is probable. When the Company capitalizes patent defense costs, it amortizes these costs over the remaining estimated useful life of the patent, which is generally 10 years. There were no such costs capitalized during either of the first nine months of fiscal years 2021 or 2020.

As of December 25, 2020, annual amortization expense of intangible assets for the next five fiscal years is expected to be as follows:


Remainder of 2021	$	850
2022	3,293
2023	3,139
2024	3,003
2025	2,709
Thereafter	23,426
Total	$	36,420
