Commitments and Contingencies Disclosure [Abstract]
Litigation	Litigation We are involved in various routine and other specific legal proceedings, including the following which are described in Note 22 within our 2018 10-K: Colombia litigation, SNAI litigation, Washington State Matter, and the Raqqa Matter. There have been no material changes to these matters since the 2018 10-K was filed with the SEC, except as described below. We record an accrual for legal contingencies when it is both probable that a liability has been incurred and the amount or range of the loss can be reasonably estimated (although, as discussed below, there may be an exposure to loss in excess of the accrued liability). We evaluate our accruals for legal contingencies at least quarterly and, as appropriate, establish new accruals or adjust existing accruals to reflect (1) the facts and circumstances known to us at the time, including information regarding negotiations, settlements, rulings and other relevant events and developments, (2) the advice and analyses of counsel and (3) the assumptions and judgment of management. Legal costs associated with our legal proceedings are expensed as incurred. We had accrued liabilities of $3 million and $4 million for all of our legal matters that were contingencies as of June 30, 2019 and December 31, 2018, respectively. Substantially all of our legal contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss involves a series of complex judgments about future events. Consequently, the ultimate outcomes of our legal contingencies could result in losses in excess of amounts we have accrued. We may be unable to estimate a range of possible losses for some matters pending against us or our subsidiaries, even when the amount of damages claimed against us or our subsidiaries is stated because, among other things: (1) the claimed amount may be exaggerated or unsupported; (2) the claim may be based on a novel legal theory or involve a large number of parties; (3) there may be uncertainty as to the likelihood of a class being certified or the ultimate size of the class; (4) there may be uncertainty as to the outcome of pending appeals or motions; (5) the matter may not have progressed sufficiently through discovery or there may be significant factual or legal issues to be resolved or developed; and/or (6) there may be uncertainty as to the enforceability of legal judgments and outcomes in certain jurisdictions. Other matters have progressed sufficiently that we are able to estimate a range of possible loss. For those legal contingencies disclosed in Note 22 in our 2018 10-K and this Note 16 as well as those related to the previously disclosed settlement agreement entered into in February 2015 with SNAI S.p.a., as to which a loss is reasonably possible, whether in excess of a related accrued liability or where there is no accrued liability, and for which we are able to estimate a range of possible loss, the current estimated range is up to approximately $14 million in excess of the accrued liabilities (if any) related to those legal contingencies. This aggregate range represents management’s estimate of additional possible loss in excess of the accrued liabilities (if any) with respect to these matters based on currently available information, including any damages claimed by the plaintiffs, and is subject to significant judgment and a variety of assumptions and inherent uncertainties. For example, at the time of making an estimate, management may have only preliminary, incomplete, or inaccurate information about the facts underlying a claim; its assumptions about the future rulings of the court or other tribunal on significant issues, or the behavior and incentives of adverse parties, regulators, indemnitors or co‑defendants, may prove to be wrong; and the outcomes it is attempting to predict are often not amenable to the use of statistical or other quantitative analytical tools. In addition, from time to time an outcome may occur that management had not accounted for in its estimate because it had considered that outcome to be remote. Furthermore, as noted above, the aggregate range does not include any matters for which we are not able to estimate a range of possible loss. Accordingly, the estimated aggregate range of possible loss does not represent our maximum loss exposure. Any such losses could have a material adverse impact on our results of operations, cash flows or financial condition. The legal proceedings underlying the estimated range will change from time to time, and actual results may vary significantly from the current estimate. TCS John Huxley Matter On March 15, 2019, TCS John Huxley America, Inc., TCS John Huxley Europe Ltd., TCS John Huxley Asia Ltd., and Taiwan Fulgent Enterprise Co., Ltd. brought a civil action in the United States District Court for the Northern District of Illinois against SGC, Bally Technologies, Inc. and Bally Gaming, Inc. In the complaint, the plaintiffs assert federal antitrust claims arising from the defendants’ procurement of particular U.S. and South African patents. The plaintiffs allege that the defendants used those patents to create an allegedly illegal monopoly in the market for automatic card shufflers sold to regulated casinos in the United States. On April 10, 2019, the defendants filed a motion to dismiss the plaintiffs’ complaint with prejudice. On April 25, 2019, the district court denied the defendants’ motion to dismiss without prejudice pursuant to the court’s local rules, after the plaintiffs advised that they intended to file an amended complaint. The plaintiffs filed their amended complaint on May 3, 2019, and on May 22, 2019, the defendants filed a motion to dismiss the plaintiffs’ amended complaint with prejudice, which has not yet been ruled upon by the district court. We are currently unable to determine the likelihood of an outcome or estimate a range of reasonably possible loss.
