(a)	In the first quarter and second quarter of 2023, we issued common stock from treasury shares for stock options exercised, restricted stock grants, and purchases under our employee stock purchase plan. As a result, additional paid in capital was reduced to zero as of the end of each period, which resulted in a reduction of retained earnings by $3 million and $82 million, respectively. Future issuances from treasury shares could similarly impact additional paid in capital and retained earnings.
