The International Boxing Federation announced a pension plan for its fighters, a move officials said is designed to erase the image of down-and-out former boxers.

The IBF plan requires all champions and challengers in title fights to contribute 2% percent of each purse to the pension plan, up to a maximum of $30,000 annually.

Other IBF fighters may contribute 2 percent from their non-championship purses. Officials said they decided to make the contribution voluntary for those fights because the purses are closer to $500 than $500,000, and the boxer may decide he can’t afford to have money withdrawn.
