OVERLAND PARK, Kan. (AP) — Sprint Corp. has signaled that job cuts are underway as the nation’s third-largest wireless company seeks to cut costs amid heightened competition.

The Overland Park-based company said Friday in a regulatory filing that the workforce reduction of management and non-management positions will result in a $160 million expense for severance and other costs in the fiscal second quarter.

The Kansas City Star eports that the job cuts started Tuesday and will largely be completed by Oct. 31. The filing with the Securities and Exchange Commission didn’t specify how many jobs will be lost.

Sprint’s new chief executive, Marcelo Claure, has told employees to expect cost cuts and a more vigorous competitive edge.

Sprint has about 33,000 employees, down from 36,000 the company reported as of the end of March.
