Commitments and Contingencies Disclosure [Abstract]
Commitments and contingent liabilities	Note 13 — Commitments and contingent liabilities Environmental: The Company is subject to contingencies as a result of environmental laws and regulations that in the future may require the Company to take further action to correct the effects on the environment of prior disposal practices or releases of chemical or petroleum substances by the Company or other parties. Much of this liability results from the U.S. Comprehensive Environmental Response, Compensation and Liability Act, often referred to as Superfund, the U.S. Resource Conservation and Recovery Act and similar state laws. These laws require the Company to undertake certain investigative and remedial activities at sites where the Company conducts or once conducted operations or at sites where Company-generated waste was disposed. Remediation activities vary substantially in duration and cost from site to site. These activities, and their associated costs, depend on the mix of unique site characteristics, evolving remediation technologies, the regulatory agencies involved and their enforcement policies, as well as the presence or absence of other potentially responsible parties. At April 2, 2017, the Company has recorded $1.1 million and $5.6 million in accrued liabilities and other liabilities, respectively, relating to these matters. Considerable uncertainty exists with respect to these liabilities and, if adverse changes in circumstances occur, the potential liability may exceed the amount accrued as of April 2, 2017. The time frame over which the accrued amounts may be paid out, based on past history, is estimated to be 15-20 years. Litigation: The Company is a party to various lawsuits and claims arising in the normal course of business. These lawsuits and claims include actions involving product liability, intellectual property, employment, environmental and other matters. As of April 2, 2017, the Company has recorded accrued liabilities of $2.4 million in connection with such contingencies, representing its best estimate of the cost within the range of estimated possible losses that will be incurred to resolve these matters. Of the amount accrued as of April 2, 2017, $1.7 million pertains to discontinued operations. During the first quarter 2017, Teleflex Medical Trading (Shanghai) Company, Ltd. (“Teleflex Shanghai”), one of the Company’s subsidiaries, eliminated a key distributor within its sales channel in China and undertook a distributor to direct sales conversion within that channel. On March 24, 2017, the distributor submitted an application for arbitration alleging, among other things, that Teleflex Shanghai wrongfully terminated its relationship with the distributor. The distributor is seeking $10.1 million (RMB 69.3 million) in damages for alleged costs of transportation and dismissal of personnel, as well as lost estimated profits. In addition, the distributor is seeking to compel Teleflex Shanghai to repurchase, for $9.1 million (RMB 63.0 million), Teleflex products that the distributor alleges are currently held in its inventory. Teleflex Shanghai intends to vigorously contest the distributor’s arbitration claim, and has filed a counterclaim seeking payment from the distributor of $8.9 million (RMB 61.2 million) in respect of outstanding trade receivables owed by the distributor to Teleflex Shanghai. At this time, the Company is unable to make an estimate of the amount of loss, if any, or range of possible loss that the Company could incur as a result of this matter. In 2006, the Company was named as a defendant in a wrongful death product liability lawsuit filed in the Louisiana State District Court for the Parish of Calcasieu, involving a product manufactured by the Company’s former marine business. In September 2014, the case was tried before a jury, which returned a verdict in favor of the Company. The plaintiff subsequently filed a motion for a new trial, which was granted, and the case was re-tried before a jury in December 2014. On December 5, 2014, the jury returned a verdict in favor of the plaintiff, awarding $0.1 million in compensatory damages and $23.0 million in punitive damages, plus pre- and post-judgment interest on the compensatory damages and post-judgment interest on the punitive damages. The Company filed an appeal with the Louisiana Court of Appeal, and the plaintiff filed a cross-appeal, seeking to overturn the trial court’s denial of pre-judgment interest on the punitive damages award. On June 29, 2016, the Louisiana Court of Appeal affirmed the trial court verdict in all respects. The Company and the plaintiff filed applications for a writ of certiorari (a request for review) to the Louisiana Supreme Court. On January 13, 2017, the Louisiana Supreme Court granted the Company's writ application. Oral arguments were held on May 1, 2017 and the parties currently are awaiting the court’s decision. As of April 2, 2017, the Company has accrued a liability representing its best estimate of probable loss associated with this matter, which is included in the Company’s accrued liabilities for litigation matters relating to discontinued operations discussed in the preceding paragraph. The Company believes that any liability arising from this matter that is not covered by the Company's product liability insurance will not exceed $10.0 million. Based on information currently available, advice of counsel, established reserves and other resources, the Company does not believe that the outcome of any outstanding litigation and claims is likely to be, individually or in the aggregate, material to its business, financial condition, results of operations or liquidity. However, in the event of unexpected further developments, it is possible that the ultimate resolution of these matters, or other similar matters, if unfavorable, may be materially adverse to the Company’s business, financial condition, results of operations or liquidity. Legal costs such as outside counsel fees and expenses are charged to selling, general and administrative expenses in the period incurred. Tax audits and examinations: The Company and its subsidiaries are routinely subject to tax examinations by various tax authorities. As of April 2, 2017, the most significant tax examinations in process are in Canada and Germany. The Company may establish reserves with respect to its uncertain tax positions, after which it adjusts its reserves to address developments with respect to these uncertain tax positions. Accordingly, developments in tax audits and examinations, including resolution of uncertain tax positions, could result in increases or decreases to the Company’s recorded tax liabilities, which could impact the Company’s financial results. Other: The Company has various purchase commitments for materials, supplies and other items occurring in the ordinary conduct of its business. On average, such commitments are not at prices in excess of current market prices.
