Reebok International said the supply problems that have dogged it this year had been resolved, but that they will affect fourth-quarter profits. "We probably will have a fourth quarter that is under our potential," said company chairman Paul Fireman. He said Canton, Mass.-based athletic footwear maker should make 32 to 37 cents per share, compared with 27 cents a year ago. In August, Reebok said it would post only marginal profit increases in the third quarter ending Sept. 30 due to production delays. The delays were blamed on labor unrest in South Korea and contracting with unreliable producers.
