Commitments, Contingent Liabilities and Litigation	8. Commitments, Contingent Liabilities and Litigation Commitments Operating Leases The future minimum rental payments for operating leases having initial or remaining non-cancelable lease terms in excess of one year at June 30, 2016 for fiscal 2017 through 2021 and thereafter are as follows: $119 million, $100 million, $81 million, $67 million, $50 million and $127 million. Rental expense relating to operating leases was $126 million, $104 million and $107 million in fiscal 2016, 2015 and 2014, respectively. Sublease rental income was immaterial for all periods presented. Generic Sourcing Venture With CVS Health Corporation In July 2014, we established Red Oak Sourcing, LLC ("Red Oak Sourcing"), a U.S.-based generic pharmaceutical sourcing venture with CVS Health with an initial term of 10 years. Red Oak Sourcing negotiates generic pharmaceutical supply contracts on behalf of both companies. We are required to pay 39 quarterly payments of $25.6 million to CVS Health which commenced in October 2014. Due to the achievement of predetermined milestones, the quarterly payment to CVS Health increased by $10 million beginning in fiscal 2016 and by an additional $10 million beginning in the first quarter of fiscal 2017, resulting in a maximum quarterly payment of $45.6 million. Legal Proceedings We become involved from time to time in disputes, litigation, and regulatory matters. We may be named from time to time in qui tam actions, which are initiated by private third parties purporting to act on behalf of federal or state governments and which allege that false claims have been submitted or have been caused to be submitted for payment by the government. After a private party has filed a qui tam action, the government must investigate the private party's claim and determine whether to intervene in and take control over the litigation. These actions may remain under seal while the government makes this determination. If the government declines to intervene, the private party may nonetheless continue to pursue the litigation on his or her own on behalf of the government. From time to time, we receive subpoenas or requests for information from various government agencies relating to our business or to the business of a customer, supplier, or other industry participant. Most of these matters are resolved without incident; however, such subpoenas or requests can lead to the assertion of claims or the commencement of legal proceedings against us. From time to time, we may determine that products we manufacture or market do not meet our specifications, regulatory requirements, or published standards. When we or a regulatory agency identify a quality or regulatory issue, we investigate and take appropriate corrective action. Such actions can lead to product recalls, costs to repair or replace affected products, temporary interruptions in product sales, action by regulators, and product liability claims and lawsuits, including class actions. We accrue for contingencies related to disputes, litigation, and regulatory matters if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because these matters are inherently unpredictable and unfavorable developments or resolutions can occur, assessing contingencies is highly subjective and requires judgments about future events. We regularly review contingencies to determine whether our accruals and related disclosures are adequate. The amount of ultimate loss may differ from these estimates. With respect to the matters described below, we are unable to estimate a range of reasonably possible loss for matters for which there is no accrual, or additional loss for matters for which we have recorded an accrual, since damages or fines have not been specified or the proceedings are at stages where significant uncertainty exists as to legal or factual issues and as to whether such matters will proceed to trial. We do not believe, based on currently available information, that the outcomes of these matters will have a material adverse effect on our financial position, results of operations, or cash flows. However, the outcome of one or more of these matters could be material to our results of operations for a particular quarterly period. We recognize income from the favorable outcome of litigation when we receive the associated cash or assets. We recognize estimated loss contingencies for litigation and regulatory matters and income from favorable resolution of litigation in litigation (recoveries)/charges, net in our consolidated statements of earnings. DEA Investigation and Related Matters In February 2012, the U.S. Drug Enforcement Administration (the "DEA") issued an order to show cause and immediate suspension of our Lakeland, Florida distribution center's registration to distribute controlled substances, asserting that we failed to maintain required controls against the diversion of controlled substances. In May 2012, we entered into a settlement agreement with the DEA that resolved the administrative aspects of the DEA's action but did not resolve potential liability for civil fines in Florida or elsewhere for the conduct covered by the settlement agreement. In that regard, we are continuing to discuss a settlement with the U.S. Department of Justice. We incurred litigation charges of $3 million and $41 million for this matter during fiscal 2016 and 2015, respectively. Our total accrual for this matter at June 30, 2016 and 2015 was $44 million and $41 million, respectively, which is included in other accrued liabilities in the consolidated balance sheets. State of West Virginia vs. Cardinal Health, Inc. Since June 2012, the West Virginia Attorney General has filed complaints against a number of pharmaceutical wholesale distributors, including us. The complaints, which were filed in the Circuit Court of Boone County, West Virginia, allege, among other things, that the distributors failed to maintain effective controls to guard against diversion of controlled substances in West Virginia, failed to report suspicious orders of controlled substances in accordance with the West Virginia Uniform Controlled Substances Act, and were negligent in distributing controlled substances to pharmacies that serve individuals who abuse controlled substances. The complaints seek, among other things, injunctive and other equitable relief and monetary damages. We are vigorously defending ourselves in this matter. Product Liability Lawsuits We and our Cordis business have been named as defendants in product liability lawsuits, including at August 9, 2016, 18 lawsuits involving claims by approximately 180 plaintiffs that allege personal injuries associated with the use of Cordis OptEase and TrapEase inferior vena cava (IVC) filter products. These lawsuits seek a variety of remedies, including unspecified monetary damages. We are vigorously defending ourselves in these matters. Antitrust Litigation Proceeds We received and recognized income resulting from settlements of class action antitrust lawsuits, in which we were a class member, of $80 million, $71 million and $24 million during fiscal 2016, 2015 and 2014, respectively.
