This study investigates the changes in dividend payout modes and financing sources made by firms during the subprime mortgage crisis, as well as the interaction between these two financial decisions. In order to mitigate the effects of information asymmetry, I focus on the Taiwanese companies for which data on domestic credit ratings are publicly available for the years 2006 through 2010. The empirical results indicate that the probability of initiating a stock repurchase program was higher than the probability of paying cash dividends during the subprime mortgage crisis. At the same time, bank loans undertaken by firms increased due to their higher financial flexibility, and seasoned equity offerings decreased. In addition, the changes in financing sources substantially influenced how firms chose their dividend payment modes. The overall evidence suggests that when firms experience an external credit crunch, financial flexibility is the key factor that dominates their financing and dividend-payout decisions.
