Purchase and Capital Commitments—At March 31, 2017, purchase commitments were $115 million for the remainder of 2017, $77 million for 2018, $50 million for 2019, $42 million for 2020, $26 million for 2021 and $134 million thereafter.

Letters of Credit—At March 31, 2017, we had outstanding letters of credit, bank guarantees, and performance bonds of $60 million, of which $35 million were letters of credit issued under the UBS Revolver, $18 million were bank guarantees and letters of credit issued by ABSA, $5 million were bank guarantees issued by Standard Bank and $2 million were performance bonds issued by Westpac Banking Corporation.

Other Matters— From time to time, we may be party to a number of legal and administrative proceedings involving legal, environmental, and/or other matters in various courts or agencies. These proceedings, individually and in the aggregate, may have a material adverse effect on us. These proceedings may be associated with facilities currently or previously owned, operated or used by us and/or our predecessors, some of which may include claims for personal injuries, property damages, cleanup costs, and other environmental matters. Current and former operations may also involve management of regulated materials that are subject to various environmental laws and regulations including the Comprehensive Environmental Response Compensation and Liability Act, the Resource Conservation and Recovery Act or state equivalents. Similar environmental laws and regulations and other requirements exist in foreign countries in which we operate. Currently, we are not party to any pending legal or administrative proceedings that may have a material adverse effect, either individually or in the aggregate, on our business, financial condition or results of operations.
