Hewlett-Packard CEO Meg Whitman's 10-year stretch as the head of eBay was seen as a landmark for women in business. But eBay -- and most major companies in the U.S. -- are still headed mostly by men.

A new report out Thursday shows eBay and others are doing a poor job when it comes to promoting women and minorities to their executive suites and corporate boards. Maryland-based Calvert Investments issued the periodical report. It analyzes the diversity of companies in the Standard & Poors 100, a stock index that includes many of the country's top firms.

In the report, eBay itself is fourth from the bottom, receiving 30 points for diversity efforts out of 100. Host Stephanie Martin talks with Christine DeGroot, the report's lead author.
