Canon has confirmed it will not look to terminate its sponsorship deal with the IAAF but remains undecided on a future relationship.
Reports on Monday suggested Adidas would end its contract with athletics' governing body four years early due to the ongoing doping and corruption scandals in the sport.
Adidas released a statement to say it was in "close contact" with the IAAF as the saga rumbles on, but did not confirm its plans.
When approached by Omnisport, another official sponsor - Canon - said it would continue to be associated with the IAAF during this Olympic year, but that its contract only runs until December 31.
"Canon Inc's current sponsorship contract with IAAF runs until 31 December 2016," the Japanese company said in a statement. "We have no intention to terminate the contract before that date.
"It is not determined yet whether Canon will renew the contract or not, after the current period ends."
An independent commission led by the World Anti-Doping Agency (WADA) released the second part of its report this month, in which it said "corruption was embedded" within the IAAF and that members of its Council must have known about the extent of doping within athletics.
It was also claimed by the report's author Dick Pound that athletes from Russia and Turkey who failed drugs tests paid bribes to cover up the results.
