Product Warranties Disclosures [Abstract] |
Product Warranty Disclosure [Text Block] | Product Warranties We provide product warranties with varying terms and durations for the majority of our products. We estimate our warranty reserve by considering historical and projected warranty claims, historical and projected cost-per-claim, and knowledge of specific product issues that are outside our typical experience. We record warranty expense in cost of sales in the consolidated statement of operations. Product warranty claims not expected to occur within one year are included as part of other long-term liabilities in the consolidated balance sheets. The following table represents changes in our consolidated warranty reserve:
| Year Ended December 31,
| 2017 |  | 2016 |  | 2015
Beginning Balance | $ | 18.3 |  |  | $ | 21.0 |  |  | $ | 24.2 |
Issued - Warranty Expense | 7.1 |  |  | 8.8 |  |  | 13.7 |
Acquired - Warranty Reserve | 0.9 |  |  | — |  |  | — |
Change in Estimate - Warranty Expense | 2.1 |  |  | 1.2 |  |  | 3.0 |
Warranty Usage | (11.7 | ) |  | (12.7 | ) |  | (19.9 | )
Ending Balance | $ | 16.7 |  |  | $ | 18.3 |  |  | $ | 21.0 |
During the third quarter of 2016, we recovered for breaches of representations and warranties primarily related to warranty costs for certain product lines acquired from AirSep Corporation (“AirSep”) in 2012 under the related representation and warranty insurance. For the year ended December 31, 2016, this reduced our BioMedical segment’s cost of sales by $15.2.
