Mattel Inc. on Wednesday announced it will move 100 positions at its Fisher-Price division from New York to the toymaker’s El Segundo headquarters in coming months.

The positions are in the Fisher-Price section of Mattel’s new North American Division, which provides marketing, product release planning and other support services to retailers.

Mattel acquired Fisher-Price, based in East Aurora near Buffalo and makes toys and other products for young children, in 1993. Most of the affected positions are in East Aurora, with some employees based in New York City also affected. East Aurora’s product design and development teams are not affected by the move, according to Fisher-Price spokeswoman Brenda Andolina. Employees were informed of the change today.

Mattel said that employees who opt to relocate to Southern California will be offered relocation benefits, and those deciding not to move may be offered other positions in the New York area. Those who leave the company or are laid off will receive severance, outplacement and other transition benefits, the company said.

About two-thirds of Mattel’s 5,000 U.S. employees are based in El Segundo. Last year the company reorganized its business structure to create the North American Division in order to better serve its retail customers.

“This is sort of an evolution of what we began last year, said Alan Hilowitz, Mattel spokesman. He added that the five-building El Segundo campus has plenty of room to accommodate the relocated positions. He would not say how long employees are being given to make a decision or when local job openings would be announced.
