    Abstract: This study examines the effects of various operational risk events for banks from
    1990 to 2011 on stock price reaction, profitability,risk and reputational loss, as well as
    whether corporate governance can reduce the impact of operational risk. For internal-factor and external-factor events, we separately estimate both the stock abnormal returns
    (ARs) and industry-adjusted excess earnings, along with reputational losses within the ARs
    and excess earnings,for occurring, finding and announcing days, respectively. Our findings
    indicate that the internal fraud events face significantly negative ARs,excess earnings
    and reputational losses during the announcement period; the stock risks do not increase,
    and prices moderately reflect decreasing profitability.The serious disasters and events resulting from external factors face no negative excess earnings, but have negative ARs and
    reputational losses during both the occurring and announcement periods. Moreover, the
    post-event stock nonsystematic risks increase and stock prices have overreactions.Based on
    regression analyses, among corporate governance mechanisms, information disclosure and
    insider ownership can reduce nonsystematic risks and alleviate the impact of operational
    and reputational losses on market values; meanwhile, no significant effect for the other
    mechanisms is observed.
