Commitments, Contingent Liabilities and Litigation	9. 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, 2018 for fiscal 2019 through 2023 and thereafter are as follows: $113 million, $97 million, $77 million, $58 million, $41 million and $103 million. Rental expense relating to operating leases was $172 million, $159 million and $126 million in fiscal 2018, 2017 and 2016, respectively. Sublease rental income was immaterial for all periods presented. Generic Sourcing Venture With CVS Health Corporation Red Oak Sourcing, LLC ("Red Oak Sourcing") is a U.S.-based generic pharmaceutical sourcing venture with CVS Health for an initial term through June 2024. Red Oak Sourcing negotiates generic pharmaceutical supply contracts on behalf of its participants. Due to the achievement of predetermined milestones, we are required to make quarterly payments of $45.6 million to CVS Health for the initial term. Contingencies New York Opioid Stewardship Act In April 2018, the State of New York passed a budget which included the Opioid Stewardship Act (the "OSA"). The OSA created an aggregate $100 million annual assessment on all manufacturers and distributors licensed to sell or distribute opioids in New York. Each licensed manufacturer and distributor will be required to pay a portion of the assessment based on its ratable share, as determined by the state, of the total morphine milligram equivalents sold or distributed in New York during the applicable calendar year. The initial payment is due on January 1, 2019 for opioids sold or distributed during calendar year 2017. We accrue for contingencies if it is probable that a liability has been incurred and the amount can be reasonably estimated. At this time, we believe that it is probable that we owe an amount under the OSA for calendar years 2017 and 2018, but we are unable to estimate the amount because of uncertainties with respect to the implementation of the assessment and because the information necessary to determine our share of the assessment is not yet available. 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 initiated by private third parties. In such actions, the private parties purport to act on behalf of federal or state governments, allege that false claims have been submitted for payment by the government and may receive an award if their claims are successful. 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 purporting to act on behalf of the government. From time to time, we become aware through employees, internal audits or other parties of possible compliance matters, such as complaints or concerns relating to accounting, internal accounting controls, financial reporting, auditing, or other ethical matters or relating to compliance with laws such as healthcare fraud and abuse, anti-corruption or anti-bribery laws. When we become aware of such possible compliance matters, we investigate internally and take appropriate corrective action. In addition, from time to time, we receive subpoenas or requests for information from various federal or state agencies relating to our business or to the business of a customer, supplier or other industry participants. Internal investigations, subpoenas or requests for information could lead to the assertion of claims or the commencement of legal proceedings against us or result in sanctions. 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 potential 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. Even absent an identified regulatory or quality issue or product recall, we can become subject to product liability claims and lawsuits. 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. We recognize income from the favorable outcome of litigation when we receive the associated cash or assets. We recognize estimated loss contingencies for certain litigation and regulatory matters and income from favorable resolution of litigation in litigation (recoveries)/charges in our consolidated statements of earnings. Opioid Lawsuits Pharmaceutical wholesale distributors, including us, have been named as defendants in over 1,000 lawsuits relating to the distribution of prescription opioid pain medications. These lawsuits have been filed in various federal, state, and other courts by a variety of plaintiffs, which are primarily counties, municipalities and political subdivisions from 48 states. Plaintiffs also include state attorneys general, unions and other health and welfare funds, hospital systems and other healthcare providers. Of these lawsuits, 32 are purported class actions. The lawsuits seek equitable relief and monetary damages based on a variety of legal theories including various common law claims, such as negligence, public nuisance, unjust enrichment as well as violations of controlled substance laws and various other statutes. Many also name pharmaceutical manufacturers, retail pharmacy chains and other entities as defendants. The vast majority of these lawsuits have been filed in U.S. federal court and have been transferred for consolidated pre-trial proceedings in a Multi-District Litigation proceeding in the United States District Court for the Northern District of Ohio. The court, among other things, ordered that three lawsuits proceed to trial in 2019 depending on the outcome of pre-trial motions. As a part of these proceedings, distributors have engaged in preliminary discussions with various parties, including state attorneys general, regarding possible resolution structures. In addition, 39 state attorneys general have formed a multi-state task force to investigate the manufacturing, distribution, dispensing and prescribing practices of opioid medications. We have received requests related to this multi-state investigation, as well as civil investigative demands, subpoenas or requests for information from these and other state attorneys general offices. We are cooperating with the offices conducting these investigations. We are vigorously defending ourselves in all of these opioid matters. Since all of the above-referenced lawsuits and investigations are in early stages, we are unable to predict their outcome or estimate a range of reasonably possible losses. Product Liability Lawsuits As of August 20, 2018, we are named as a defendant in 174 product liability lawsuits filed in Alameda County Superior Court in California involving claims by approximately 1,918 plaintiffs that allege personal injuries associated with the use of Cordis OptEase and TrapEase inferior vena cava (IVC) filter products. Another 20 lawsuits involving similar claims by approximately 21 plaintiffs are pending in other jurisdictions. These lawsuits seek a variety of remedies, including unspecified monetary damages. We are vigorously defending ourselves in these lawsuits. At June 30, 2018, we had a total of $259 million, net of expected insurance recoveries, accrued for losses and legal defense costs related to the Cordis IVC filter lawsuits. While we have recorded accruals based on our assessment of these matters, because these lawsuits are in early stages, we are unable to estimate a range of reasonably possible losses in excess of this accrued amount.
