In the wake of Haiti's devastating earthquake a year ago, dozens of major non-profit organizations and philanthropies raised over a billion dollars in relief aid for the devastated country.

Over the past year, those groups spent hundreds of millions to provide water, sanitation, shelter, food and other assistance to millions of Haitians. And many have carefully planned their expenditures, setting aside money for long-term projects crucially needed to rebuild Haiti. But some organizations seemed vague in their plans for how to spend millions in their coffers.

In the last year, Americans gave more than $1.4 billion in relief aid to the country, but only 38 percent of that has been spent to provide recovery and rebuilding aid, according to a Chronicle of Philanthropy survey of 60 major relief organizations. (By comparison, after Hurricane Katrina, a domestic disaster, charities spent about 80 percent of the money they had raised.)
