• Due to a production error, part of one paragraph was inserted into the middle of another in the “Much afoot in 2009” article on page 1 of the Dec. 28 issue. The paragraph, which appeared on page 35, should have read:

What investors are trying to do is get better diversification, after finding that traditional risk-reducing methods had failed in 2008.
• Some figures listed in the endowments chart on page 18 of the Dec. 28 Data Book issue were incorrectly listed in millions of dollars instead of billions.
