Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies: Leases We lease certain real and personal property under non-cancelable operating leases. Some of our lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvement funding or other lease concessions. We recognize our minimum rental expense on a straight-line basis. We amortize this expense over the term of the lease beginning with the date of initial possession, which is the date we enter the leased space and begin to make improvements in preparation for its intended use. Future annual minimum lease payments and capital lease commitments as of December 31, 2016 were as follows (in millions):
| Operating Leases |  | Capital Leases
2017 | $ | 48.3 |  |  | $ | 1.4 |

Present value of minimum payments |  |  | $ | 16.7 |
On March 22, 2013, we entered into an agreement with a financial institution to renew the lease of our corporate headquarters in Richardson, Texas for a term of approximately six years through March 1, 2019 (the “Lake Park Renewal”). The leased property consists of an office building of approximately 192,000 square feet, land and related improvements. During the lease term, the Lake Park Renewal requires us to pay base rent in quarterly installments, payable in arrears. At the end of the lease term, we must do one of the following: (i) purchase the property for $41.2 million; (ii) vacate the property and return it in good condition; (iii) arrange for the sale of the leased property to a third party; or (iv) renew the lease under mutually agreeable terms. If we elect to sell the property to a third party and the sales proceeds are less than the lease balance, we must pay any such deficit to the financial institution. Any such deficit payment cannot exceed 86% of the lease balance. The Lake Park Renewal is classified as an operating lease and its future annual minimum lease payments are included in the table above. Our obligations under the Lake Park Lease are secured by a pledge of our interest in the leased property. The Lake Park Renewal contains customary lease covenants and events of default as well as events of default if (i) indebtedness of $75 million or more is not paid when due, (ii) there is a change of control or (iii) we fail to comply with certain covenants incorporated from our Sixth Amended and Restated Credit Facility Agreement. We believe we were in compliance with these financial covenants as of December 31, 2016. Environmental Environmental laws and regulations in the locations we operate can potentially impose obligations to remediate hazardous substances at our properties, properties formerly owned or operated by us, and facilities to which we have sent or send waste for treatment or disposal. We are aware of contamination at some facilities; however, we do not believe that any future remediation related to those facilities will be material to our results of operations. Total environmental accruals are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):
| As of December 31,
| 2016 |  | 2015
Accrued expenses | $ | 1.2 |  |  | $ | 1.3 |
Other liabilities | 4.4 |  |  | 4.0 |
Total environmental accruals | $ | 5.6 |  |  | $ | 5.3 |
Future environmental costs are estimates and may be subject to change due to changes in environmental remediation regulations, technology or site-specific requirements. Product Warranties and Product Related Contingencies We incur the risk of liability for claims related to the installation and service of heating and air conditioning products, and we maintain liabilities for those claims that we self-insure. We are involved in various claims and lawsuits related to our products. Our product liability insurance policies have limits that, if exceeded, may result in substantial costs that could have an adverse effect on our results of operations. In addition, warranty claims and certain product liability claims are not covered by our product liability insurance. Total product warranty liabilities related to continuing operations are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):
| As of December 31,
| 2016 |  | 2015
Accrued expenses | $ | 30.0 |  |  | $ | 26.7 |
Other liabilities | 71.1 |  |  | 65.6 |
Total product warranty liabilities | $ | 101.1 |  |  | $ | 92.3 |
The changes in product warranty liabilities related to continuing operations for the years ended December 31, 2016 and 2015 were as follows (in millions):
Total warranty liability as of December 31, 2014 | $ | 87.2 |
Payments made in 2015 | (27.2 | )

Total warranty liability as of December 31, 2016 | $ | 101.1 |
We have incurred, and will likely continue to incur, product costs not covered by insurance or our suppliers’ warranties, which is not included in the estimated warranty liabilities tables immediately above. Also, to satisfy our customers and protect our brands, we have repaired or replaced installed products experiencing quality-related issues, and will likely continue such repairs and replacements. We currently estimate our probable liability for a certain supplier quality issue within a range of $0.9 million and $9.1 million with all amounts in that range equally likely. We have accrued a $0.9 million liability in Accrued expenses on the Consolidated Balance Sheet at December 31, 2016. The supplier is reimbursing the majority of costs related to this liability. Self-Insurance We use a combination of third-party insurance and self-insurance plans to provide protection against claims relating to workers' compensation/employers' liability, general liability, product liability, auto liability, auto physical damage and other exposures. We use large deductible insurance plans, written through third-party insurance providers, for workers' compensation/employers' liability, general liability, product liability and auto liability. We also carry umbrella or excess liability insurance for all third-party and self-insurance plans, except for directors' and officers' liability, property damage and certain other insurance programs. For directors' and officers' liability, property damage and certain other exposures, we use third-party insurance plans that may include per occurrence and annual aggregate limits. We believe the deductibles and liability limits for all of our insurance policies are appropriate for our business and are adequate for companies of our size in our industry. We maintain safety and manufacturing programs that are designed to remove risk, improve the effectiveness of our business processes and reduce the likelihood and significance of our various retained and insured risks. In recent years, our actual claims experience has collectively trended favorably and, as a result, both self-insurance expense and the related liability have decreased. Total self-insurance liabilities were included in the following captions on the accompanying Consolidated Balance Sheets (in millions):
| As of December 31,
| 2016 |  | 2015
Accrued expenses | $ | 8.2 |  |  | $ | 9.2 |
Other liabilities | 22.7 |  |  | 23.9 |
Total self-insurance liabilities | $ | 30.9 |  |  | $ | 33.1 |
Litigation We are involved in a number of claims and lawsuits incident to the operation of our businesses. Insurance coverages are maintained and estimated costs are recorded for such claims and lawsuits, including costs to settle claims and lawsuits, based on experience involving similar matters and specific facts known. Some of these claims and lawsuits allege personal injury or health problems resulting from exposure to asbestos that was integrated into certain of our products. We have never manufactured asbestos and have not incorporated asbestos-containing components into our products for several decades. A substantial majority of asbestos-related claims have been covered by insurance or other forms of indemnity or have been dismissed without payment. The remainder of our closed cases have been resolved for amounts that are not material, individually or in the aggregate. Our defense costs for asbestos-related claims are generally covered by insurance; however, our insurance coverage for settlements and judgments for asbestos-related claims vary depending on several factors, and are subject to policy limits, so we may have greater financial exposure for future settlements and judgments. For the years ended December 31, 2016, 2015 and 2014, we recorded expense of $6.3 million, $3.0 million and $0.9 million, respectively, net of probable insurance recoveries, for known and future asbestos-related litigation. In October 2016, we self-reported to the Securities and Exchange Commission (SEC) and the Department of Justice (DOJ) an alleged payment in the amount of 30,000 rubles (approximately US $475) to a Russian customs broker or official. Under the oversight of our Audit Committee, we initiated an investigation into this matter with the assistance of external legal counsel and external forensic accountants. The alleged payment was purportedly made to release a shipment of goods being held by Russian customs officials due to inaccurate paperwork. The value of the shipment was approximately €62,000 (approximately US $68,500). The allegations are related to our subsidiary in Russia, which had 2016 annual sales of approximately US $4 million. The scope of the investigation was later expanded to include our operations in Poland because our operations in Russia and Poland used the same third-party logistics provider. To date, the investigation has not resulted in any evidence of other potentially improper payments. However, the investigation has raised questions regarding possible irregularities with respect to possible non-compliance with customs documents and procedures related to these operations. The investigation is ongoing. We continue to fully cooperate with the SEC and the DOJ regarding this matter. We do not anticipate any material adverse effect on our business or financial condition as a result of this matter. It is management's opinion that none of these claims or lawsuits or any threatened litigation will have a material adverse effect, individually or in the aggregate, on our financial condition, results of operations or cash flows. Claims and lawsuits, however, involve uncertainties and it is possible that their eventual outcome could adversely affect our results of operations in a future period.
