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 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 the 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, (ii) design activities related to wheelchairs and power beds that take place at the impacted Elyria, Ohio 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 at the impacted facilities, 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 to acceptance by, the FDA. The last of these reports was accepted by the FDA during the second quarter of 2017, after which the company submitted its own report to the FDA, and the FDA initiated a reinspection of the company’s Corporate and Taylor Street facilities. At the conclusion of the inspection, the FDA issued its inspectional observations on Form 483, and the company timely filed its response. On July 24, 2017, FDA notified the company that it is in substantial compliance with the FDA's Quality System Regulation ("QSR") and that the company is permitted to resume full operations at the Corporate and Taylor Street facilities. The consent decree requires the company to undergo five years of audits by a third-party expert auditor selected by the company to determine whether the facilities are in continuous compliance with FDA's QSR and the consent decree. The third-party expert will audit the Corporate and Taylor Street facilities’ activities every six months during the first year following the July 25, 2017 resumption of full operations and then every 12 months for the next four years thereafter. 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. Recent inspections for which follow-up remains ongoing are summarized in the following paragraphs. 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. Accordingly, the company expects that the FDA will from time to time, inspect substantially all of the company's domestic and foreign FDA-registered operational facilities. In November 2017, the FDA inspected the company’s Top End facility in Pinellas Park, Florida and issued its inspectional observations on Form 483. The company intends to submit its responses to the agency in a timely manner. In September 2017, Alber GmbH, a wholly owned subsidiary of the company, received a warning letter from the FDA. The warning letter requires completion of corrective actions to address the FDA Form 483 observations following an inspection of Alber’s facility in Albstadt, Germany in May 2017. As a consequence of the warning letter, Alber Twion Power Assist devices will not be imported into the United States until all findings are corrected to FDA’s satisfaction. Although the company does not expect this action to have a significant impact on its financial results, it takes FDA’s observations very seriously and is working diligently to address these observations and respond to FDA’s warning letter in a timely manner. The Albstadt facility was previously inspected by the FDA in August 2014. In October 2014, the FDA inspected the company’s facility in Sanford, Florida and issued its inspectional observations on Form 483, and the company timely filed its response. The Sanford facility is the subject of a warning letter from the FDA issued to the company in December 2010 related to quality systems processes and procedures and the company continues to work on addressing the FDA’s citations. 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. While the FDA did notify the company on July 24, 2017 that it was 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. As described above, because the previous limitations on production imposed by the FDA consent decree were not permanent in nature, and partial production was allowed, the company does not anticipate any major repair, replacement or scrapping of its fixed assets at the Taylor Street manufacturing facility. Based on the company's expectations at the time of filing of this Quarterly Report on Form 10-Q with respect to the utilization of raw material and with respect to expected future cash flows from production at the Taylor Street manufacturing facility, the company concluded that there was no impairment in the value of the fixed assets related to the Taylor Street manufacturing facility at September 30, 2017. The majority of the production from the Taylor Street facility is "made to order" customized wheelchairs for customers and, as a result, there was not a significant amount of finished goods inventory on hand at September 30, 2017, and the inventory is expected to be fully utilized. Accordingly, the company concluded that there was not an impairment of the work in process and finished goods at the Taylor Street facility at September 30, 2017. Further, based on its analysis of the raw material inventory at the Taylor Street facility and the company's receipt of FDA's notification that the company can resume full operations at the affected facilities, the company concluded that the value of the inventory was not excessive nor impaired at September 30, 2017. 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.
