Deferred Tax Assets, Operating Loss Carryforwards, State and Local $ 21  
[1] Federal and state deferred tax assets of $21 million and $1 million, respectively, related to net operating losses were acquired as part of the Company’s April 2020 equipment finance acquisition and the December 2021 commercial real estate lender acquisition. While the federal and certain state net operating losses may be subject to certain annual utilization limits, the Company has determined that a valuation allowance is not necessary based on projected annual limitation and the length of the net operating loss carryover period.
