We provide new evidence on the value of independent directors by exploiting exogenous events that seriously distract independent directors. Approximately 20% of independent directors are significantly distracted in a typical year. They attend fewer meetings, trade less frequently in the firm's stock, and resign from the board more frequently, indicating declining firm-specific knowledge and a reduced board commitment. Firms with more preoccupied independent directors have declining firm valuation and operating performance and exhibit weaker merger and acquisition (M&A) profitability and accounting quality. These effects are stronger when distracted independent directors play key board monitoring roles and when firms require greater director attention.
