Set your alarm clocks. No sleeping late this Saturday.
Warren Buffett's Berkshire Hathaway will post its 2010 Annual Report and Q4 earnings on www.berkshirehathaway.com tomorrow morning "at approximately" 8 AM ET.
Along with extensive information on Berkshire's financials, the Annual Report also includes Buffett's very popular and widely-read annual letter to shareholders.
With some assistance from Fortune's Carol Loomis as editor, the letter is a straight-forward, folksy and funny, review of Berkshire's wins and losses over the previous year.
Buffett also uses the letter to discuss his investment strategies and to explain, and sometimes criticize, trends in the financial world and the economy.
This time around, some investors will be looking for "insights on who will run the company after the 80-year-old billionaire is gone."
