(a) In the first quarter of 2024, we issued common stock from treasury shares for stock options exercised, restricted stock grants, performance shares under our performance unit program, and purchases under our employee stock purchase plan. As a result, additional paid in capital was reduced to zero, which resulted in a reduction of retained earnings by $3 million. Future issuances from treasury shares could similarly impact additional paid in capital and retained earnings.
