7. GOODWILL AND INTANGIBLE ASSETS

Goodwill

A reconciliation of the beginning and ending balances of goodwill during the six months ended June 30, 2021 is as follows:

The Company evaluates goodwill for impairment annually during the fiscal third quarter and when an event occurs, or circumstances change such that it is reasonably possible that impairment may exist. The Company accounts for goodwill and evaluates its goodwill balances and tests them for impairment in accordance with related accounting standards. The Company performed its annual impairment assessment in its third quarter of fiscal 2020, and its analysis indicated that the Company had no impairment of goodwill.

Other Intangible Assets

A reconciliation of the beginning and ending balances of intangible assets and accumulated amortization during the six months ended June 30, 2021 and intangible assets, net as of December 31, 2020 are as follows:

Intangible assets with finite lives are amortized over their estimated useful lives. Amortization periods of assets with finite lives are based on management's estimates at the date of acquisition. The Company recorded amortization expense of $14, and $44 for the six months ended June 30, 2021, and 2020, respectively.

The Company estimates that amortization expense for our existing other intangible assets will be approximately $220 annually for each of the next five fiscal years. Actual amortization expense to be reported in future periods could differ from these estimates as a result of new intangible asset acquisitions, changes in useful lives or other relevant factors or changes.
