Intangible assets are reviewed for impairment when changes in circumstances indicate the carrying value of those assets may not be recoverable. At March 31, 2022, our market capitalization declined to a level that was less than the net book value of our stockholders’ equity. The decline in market capitalization was a triggering event that caused us to perform an impairment analysis on our long-lived assets as of March 31, 2022. Based on our analysis, the carrying values of the long-lived assets were recoverable and no impairment charge was recorded during the three months ended March 31, 2022.
