Subsequent Events [Abstract] |
Subsequent Event | Subsequent Event On October 25, 2016, ATI announced the permanent closure of the Midland, PA commodity stainless steel sheet melt and finishing facility and the Bagdad, PA grain-oriented electrical steel finishing facility. These facilities were indefinitely idled earlier in 2016, and management has concluded that the facilities cannot be operated at an acceptable rate of return. As a result of these actions, fourth quarter 2016 results are expected to include a range of $4 million to $14 million for contract termination costs, approximately $3 million of termination benefits for pension and other postretirement benefit obligations, and approximately $2 million for supplemental unemployment benefits. Cash expenditures for the contract termination and supplemental unemployment benefit costs are expected to be incurred through the first quarter of 2018.
