The companies were reacting to an investigation report published Thursday by the inspector general's office of the Global Fund to Fight AIDS, Tuberculosis and Malaria, which said the fund uncovered "serious financial wrongdoing in Cambodia."
The Geneva-based fund, which has committed aid to 151 countries since its creation in 2002, said that between 2006 and 2011 the two mosquito net suppliers paid two Cambodian officials about $410,000 to gain contracts for insecticide-treated nets that prevent the spread of malaria.
Both companies cooperated with the fund's investigation, which began in 2011, the fund said, and each of the companies took action against the employees involved.
The fund said in a statement that even though a grant in Cambodia "was compromised by the commission payments, all the mosquito nets procured by that grant were provided as intended."
