Many investors will spend Saturday morning reading Warren Buffett's annual letter to Berkshire Hathaway shareholders.

Berkshire's billionaire chairman and CEO is widely admired for his investing success and plainspoken method of explaining complex concepts.

Buffett's letter is well read in the business world because so many people follow the Oracle of Omaha, and because he often addresses general interest topics, like the economy.

Buffett's letter and the 2010 annual report for his Omaha-based company will be posted online at http://www.berkshirehathaway.com on Saturday morning.

Berkshire owns more than 80 subsidiaries, including insurance, furniture, utility, clothing, jewelry and corporate jet companies. Berkshire also has big investments in companies including Coca-Cola Co. and Wells Fargo & Co.
