On January 30, 2015, Grace borrowed on its $250 million delayed draw term loan facility and used the funds, together with cash on hand, to repurchase the warrant issued to the asbestos personal injury trust for $490 million. (See Note 8 for Chapter 11 information.)

Grace had no outstanding draws on its revolving credit facility as of September 30, 2016; however, the available credit under that facility was reduced to $253.8 million by outstanding letters of credit.

During the 2015 fourth quarter, to permit the Separation, Grace entered into an amendment to the credit agreement providing for the term loans. The amendment, which became effective upon completion of the Separation, revised certain covenants, reduced the revolving credit facility limit to $300 million and extended the facility's term to November 1, 2020. The Separation had no impact on payment or other terms of the senior notes, which remained obligations of Grace.

In connection with the Separation, GCP distributed $750 million to Grace. Grace used $600 million of those funds to repay $526.9 million of its U.S. dollar term loan and €67.3 million of its euro term loan. As a result, Grace recorded a loss on early extinguishment of debt of $11.1 million, which is included in "other (income) expense" in the Consolidated Statements of Operations.
