(a)The decrease was primarily related to the change in Pennsylvania state tax rate, expired PA net operating losses, and utilization of certain French deferred tax assets. The Chordant entities were dissolved with all DTAs written off during 2025 and well as amending French tax filings adjusting their NOL, all offset by a reclass of valuation allowance.
