Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies General In the ordinary course of its business, the company is a defendant in a number of lawsuits, primarily product liability actions in which various plaintiffs seek damages for injuries allegedly caused by defective products. All of the product liability lawsuits that the company currently faces in the United States have been referred to the company's captive insurance company and/or excess insurance carriers while all non-U.S. lawsuits have been referred to the company's commercial insurance carriers. All such lawsuits are generally contested vigorously. The coverage territory of the company's insurance is worldwide with the exception of those countries with respect to which, at the time the product is sold for use or at the time a claim is made, the U.S. government has suspended or prohibited diplomatic or trade relations. The amount recorded for identified contingent liabilities is based on estimates. Amounts recorded are reviewed periodically and adjusted to reflect additional technical and legal information that becomes available. Actual costs to be incurred in future periods may vary from the estimates, given the inherent uncertainties in evaluating certain exposures. As a medical device manufacturer, the company is subject to extensive government regulation, including numerous laws directed at preventing fraud and abuse and laws regulating reimbursement under various government programs. The marketing, invoicing, documenting, developing, testing, manufacturing, labeling, promoting, distributing and other practices of health care suppliers and medical device manufacturers are all subject to government scrutiny. Most of the company's facilities are subject to inspection at any time by the FDA or similar medical device regulatory agencies in other jurisdictions. Violations of law or regulations can result in administrative, civil and criminal penalties and sanctions, which could have a material adverse effect on the company's business. Medical Device Regulatory Matters The FDA in the United States and comparable medical device regulatory authorities in other jurisdictions regulate virtually all aspects of the marketing, invoicing, documenting, development, testing, manufacturing, labeling, promotion, distribution and other practices regarding medical devices. The company and its products are subject to the laws and regulations of the FDA and other regulatory bodies in the various jurisdictions where the company's products are manufactured or sold. The company's failure to comply with the regulatory requirements of the FDA and other applicable medical device regulatory requirements can subject the company to administrative or judicially imposed sanctions or enforcement actions. These sanctions include injunctions, consent decrees, warning letters, civil penalties, criminal penalties, product seizure or detention, product recalls and total or partial suspension of production. In December 2012, the company became subject to a consent decree of injunction filed by FDA with respect to the company's Corporate facility and its Taylor Street manufacturing facility in Elyria, Ohio. The consent decree initially limited the company's (i) manufacture and distribution of power and manual wheelchairs, wheelchair components and wheelchair sub-assemblies at or from its Taylor Street manufacturing facility, except in verified cases of medical necessity, (ii) design activities related to wheelchairs and power beds that take place at the impacted Elyria facilities and (iii) replacement, service and repair of products already in use from the Taylor Street manufacturing facility. Under the terms of the consent decree, in order to resume full operations, the company had to successfully complete independent, third-party expert certification audits at the impacted Elyria facilities, comprised of three distinct certification reports separately submitted to, and subject accepted by, FDA; submit its own report to the FDA; and successfully complete a reinspection by FDA of the company’s Corporate and Taylor Street facilities. On July 24, 2017, following its June 2017 reinspection of the Corporate and Taylor Street facilities, FDA notified the company that it is in substantial compliance with the QSR and, at that time, the company was permitted to resume full operations at those facilities including the resumption of unrestricted sales of products made in those facilities. The consent decree will continue in effect for a minimum of five years from July 24, 2017, during which time the company’s Corporate and Taylor Street facilities must complete to two semi-annual and then four annual audits performed by a company-retained expert firm. The expert audit firm will determine whether the facilities remain in continuous compliance with the FDA Act, FDA regulations and the terms of the consent decree. The FDA has the authority to inspect these facilities and any other FDA registered facility, at any time. The FDA has continued to actively inspect the company’s facilities, other than through the processes established under the consent decree. The FDA has informed the company of further upcoming inspections to its facilities, and the company believes that additional inspections beyond those for which it has been notified will likely occur in the near future. The company expects that the FDA will, from time to time, inspect substantially all the company's domestic and foreign FDA-registered facilities. Recent inspections for which follow-up remains ongoing are summarized in the following paragraphs. In June 2017, FDA inspected the company's Corporate and Taylor Street facilities in connection with the consent decree, as described above, and issued an inspectional observation on Form 483. The company submitted its response to the agency in a timely manner. On July 24, 2017, the FDA notified the company that it was in substantial compliance with the QSR and that it was permitted to resume full operations at those facilities. In September 2017, Alber GmbH, a wholly owned subsidiary of the company, received a warning letter from the FDA. The warning letter required completion of corrective actions to address FDA Form 483 observations issued following an inspection of Alber’s facility in Albstadt, Germany in May 2017. As a consequence of the warning letter, all Alber devices could not be imported into the United States until all findings were corrected to FDA’s satisfaction. On January 3, 2018, FDA notified the company that Alber’s responses to the warning letter were adequate, and that FDA had as of that date, removed the import suspension. FDA conducted its subsequent reinspection of Alber in April 2018, the result of which included no noted observations. The company expects the warning letter to be closed as a result of this inspection; however, the company cannot be assured of the timing or certainty of this outcome. In October 2017, FDA inspected the Corporate and Taylor Street facilities to investigate an anonymous complaint concerning one of the Verification of Medical Necessity documents collected by the company while subject to the restrictions under the consent decree. There were no Form 483 observations issued by FDA at the conclusion of the inspection. In November 2017, FDA inspected the company’s facility in Pinellas Park, Florida and issued its observations on Form 483, one of which was annotated as corrected and verified at the conclusion of the inspection. The company has submitted its response to FDA in a timely manner. In November 2017, the FDA inspected the company’s facility in Sanford, Florida and issued its observations on Form 483, and the company submitted its response to FDA in a timely manner. The Sanford facility is the subject of a warning letter from the FDA issued in December 2010 related to quality systems processes and procedures and the company continues to work on addressing the FDA’s citations. In November 2017, the FDA inspected the company’s facility in Porta Westfalica, Germany, and there were no inspectional observations issued at the end of the inspection. In December 2017, California Department of Public Health, acting on behalf of FDA, inspected the company's facility in Simi Valley, California and there were no inspectional observations issued at the end of the inspection. The results of regulatory claims, proceedings, investigations, or litigation are difficult to predict. An unfavorable resolution or outcome of any FDA warning letters or inspectional observations, or other FDA enforcement related to company facilities, could materially and adversely affect the company's business, financial condition, and results of operations. The limitations previously imposed by the FDA consent decree negatively affected net sales in the NA/HME segment and, to a certain extent, the Asia/Pacific segment beginning in 2012. The limitations led to delays in new product introductions. Further, uncertainty regarding how long the limitations would be in effect limited the company’s ability to renegotiate and bid on certain customer contracts and otherwise led to a decline in customer orders. Although the company has been permitted to resume full operations at the Corporate and Taylor Street facilities, the negative effect of the consent decree on customer orders and net sales in the NA/HME and Asia/Pacific segments has been considerable, and it is uncertain as to whether, or how quickly, the company will be able to rebuild net sales to more typical historical levels, irrespective of market conditions. Accordingly, when compared to the company's 2010 results, the previous limitations in the consent decree had, and likely may continue to have, a material adverse effect on the company's business, financial condition and results of operations. Separately, net sales in the NA/HME segment have likely been impacted by uncertainty on the part of the company's customers as they coped with prepayment reviews and post-payment audits by the Centers for Medicare and Medicaid Services ("CMS") and the impact of the National Competitive Bidding ("NCB") process. In addition, net sales in the NA/HME segment have and may continue to decline as a result of the company's strategic focus away from lower margin, less differentiated products as the company becomes more focused on its clinically complex products. Warranty Matters The company's warranty reserves are subject to adjustment in future periods based on historical analysis of warranty claims and as new developments occur that may change the company's estimates related to specific product recalls. See Current Liabilities in the Notes to the Consolidated Financial Statements for the total provision amounts and a reconciliation of the changes in the warranty accrual. Any of the above contingencies could have an adverse impact on the company's financial condition or results of operations.
