Legal ProceedingsFrom time to time, we are subject to various legal proceedings, regulatory matters or fines that arise in the ordinary course of business.On April 26, 2021, the Company entered into a settlement agreement with a former stockholder of the Company relating to claims arising out of the former stockholder’s sale of shares of the Company’s common stock in a private transaction prior to the Company's initial public offering. Under the settlement agreement, the Company paid $3.2 million to the former stockholder in two installments in exchange for a release of all claims made by the former stockholder against the Company in the arbitration proceeding. As of June 30, 2021, $1.7 million of the remaining settlement payment was included in accrued expenses and other current liabilities in the Consolidated Balance Sheets. The aforementioned settlement and associated legal expenses were determined to be non-deductible expenses, which resulted in an unfavorable permanent tax difference for the three and nine months ended June 30, 2021.
