Groupon Reshuffles Board After Accounting Missteps After a string of accounting missteps, Groupon is adding some financial muscle to its board. The deals site announced on Monday that it was adding two new board members: Daniel T. Henry, the chief financial officer of American Express, and Robert Bass, the departing vice chairman of Deloitte. Both executives are joining the board's audit committee. Mr. Henry, 62, a former partner with Ernst & Young, joined American Express in 1990. Mr. Bass, 62, has been a partner with Deloitte for the last 30 years. They will replace Howard Schultz, the Starbucks chief executive, and Kevin Efrusy, a partner at Accel Partners. Mr. Schultz will resign immediately while Mr. Efrusy will not stand for re-election. "With their deep financial, accounting and operational experience, Dan and Bob will provide invaluable expertise to the Board going forward," Groupon's chairman, Eric Lefkofsky, said in a statement. Groupon seems to be searching for more adult supervision in the wake of multiple issues. In late March, the company was forced to revise its financial results for the fourth quarter, increasing its losses for the period to $64.9 million from $42.3 million. Groupon acknowledged that it did not set aside sufficient capital to cover consumer returns. Last year, Groupon was also forced to drop a controversial accounting measure that excluded marketing costs from its prospectus. The fumbles have irritated shareholders, who seem to be growing impatient with the young deals site and its 31-year-old co-founder, Andrew Mason. On Monday, shares of Groupon fell once again, dropping 10.6 percent to close at $10.71 a share. The company's stock is nearly 50 percent below its I.P.O. price.
