Silicon Valley companies give generously to philanthropy: "Seven out of 10 companies created formal philanthropic guidelines as a result of the Southeast Asian tsunami, hurricanes Katrina and Rita and other disasters in 2005 and 2006, according to the study. Although local donations are helpful, the region's phenomenal wealth should prompt more generous corporate giving, said Emmett D. Carson, CEO and president of the Mountain View-based foundation."
