(a)	In the first quarter of 2022, we issued common stock from treasury shares for stock options exercised, restricted stock grants, and our employee stock purchase plan. As a result, additional paid in capital was reduced below zero, which resulted in a reduction of retained earnings by $85 million. Additional issuances from treasury shares could similarly impact additional paid in capital and retained earnings.
