6. Other Intangible Assets

A reconciliation of the beginning and ending balances of intangible assets and accumulated amortization during the three months ended March 31, 2023 and intangible assets, net as of December 31, 2022, 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 $101 and $82 for the three months ended March 31, 2023, and 2022, respectively.

The Company estimates that amortization expense for our existing other intangible assets will average $399 annually for 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.
