Using three different measures of conservatism, we document that (i) the percentage of inside directors is negatively related to conservatism, and (ii) the percentage of outside directors’ shareholdings is positively related to conservatism. Our results hold after controlling for industry, firm size, leverage, growth opportunities, institutional ownership, inside director ownership, and unobservable firm characteristics that are stable over time. Overall, the evidence is consistent with accounting conservatism assisting directors in reducing agency costs of firms.
