Empirical research finds evidence that managers use optimistic tone to signal future firm performance. However, prior literature also finds a positive relation between optimistic tone in earnings announcements and short-window abnormal returns. The market reaction to optimistic tone suggests that managers can profit from using pessimistic tone to lower the firm's stock price prior to option grants and optimistic tone to increase the stock price prior to option exercises. I hypothesize that managers adjust the tone of their earnings announcements to increase the value of their stock options. In addition, I hypothesize that managers will alter the tone to increase option payouts when the costs of doing so (proxied by litigation risk) are low and when the financial reporting incentives to do so (proxied by earnings management) are high. I test these predictions using 17,211 firm-quarter observations from 1998-2006. In my tests I regress the tone of the earnings announcement on its known determinants and indicators for a stock option grant or exercise shortly following the announcement. I do not find evidence that managers, on average, alter the tone of earnings announcements prior to option grants or exercises. However, I find that managers decrease optimistic tone prior to option grants when they also record low discretionary accruals, which suggests that altering tone and managing earnings are complementary strategies to move stock price. I also find that managers increase optimistic tone prior to option exercises when litigation risk is low, but decrease optimistic tone prior to option exercises when litigation risk is high. Further analysis indicates the litigation risk results hold only after the Sarbanes-Oxley Act of 2002. Overall, my evidence suggests that managers increase optimistic tone prior to option exercises except when a high threat of litigation constrains such opportunism. When managers do alter tone, the average financial gain is small relative to their total compensation.en-USDisclosureStock optionsTonePress releaseEarnings announcementsOptimismManagersAccountingManagementFinanceThesis
