The Business Roundtable's December 2005 CEO economic outlook survey shows that U.S. corporate leaders see broad strength in the economy moving into 2006, despite a recent series of economic challenges. The group said its CEO economic outlook index has rebounded from the post-Hurricane Katrina level of 88.2 in September to reach 101.4, a high second only to the reading of 104.4 in the first quarter of 2005. In the annual question about challenges to growth, for the third consecutive year CEOs cited healthcare as the greatest cost pressure, while energy costs supplanted litigation costs as the No. 2 concern.
