Reserve reestimates may impact future cash flows.
The declaration of dividends, the completion of the $4 billion stock repurchase program that we announced in November 2004, and our ability to service debt are subject to the impact of reserve reestimates on net income and cash flows. In addition, the declaration of dividends is subject to the discretion of our board of directors and its assessment of alternative uses of available funds. The completion of the stock repurchase program is subject to management discretion and their assessment of alternative uses of funds and the market price of Allstates common stock from time to time.
