Nestle, the world's largest food company, has terminated its sponsorship of the IAAF because of recent doping and corruption scandals.
The Swiss-based food and beverage company said in a statement that it was concerned its own reputation could be damaged by association with world athletics' governing body.
Nestle had been the main sponsor of IAAF Kids Athletics since 2012.
"We have decided to end our partnership with the IAAF Kids' Athletics programme with immediate effect," read a statement.
"This decision was taken in light of negative publicity associated with allegations of corruption and doping in sport made against the IAAF.
"We believe this could negatively impact our reputation and image and will therefore terminate our existing agreement with the IAAF."
In response, the IAAF said that they were "in discussion" with Nestle about the final year of its five-year contract.
