Subsequent Events [Abstract]
Subsequent Event	Subsequent Event: On April 3, 2019, we entered into an agreement with Pacific Life Insurance Company to purchase a group annuity contract and transfer $100.0 million of our pension plan assets and the related benefit obligations. This transaction required a remeasurement of the pension plan and we expect to recognize a $61.0 million non-cash pension settlement pre-tax loss in the second quarter of 2019 for this remeasurement.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
