Commitments and Contingencies

We are subject to a number of claims and proceedings that generally arise in the ordinary conduct of our business. These matters include, but are not limited to, general liability claims (including personal injury, product liability, and property and automobile claims), indemnification and guarantee obligations, employee injuries and employment-related claims, self-insurance obligations and contract and real estate matters. Based on advice of counsel and available information, including current status or stage of proceeding, and taking into account accruals included in our consolidated balance sheets for matters where we have established them, we currently believe that any liabilities ultimately resulting from these ordinary course claims and proceedings will not, individually or in the aggregate, have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Indemnification

The Company indemnifies its officers and directors pursuant to indemnification agreements and may in addition indemnify these individuals as permitted by Delaware law.

Operating Leases

We lease rental equipment, real estate and certain office equipment under operating leases. Certain real estate leases require us to pay maintenance, insurance, taxes and certain other expenses in addition to the stated rental payments. Future minimum lease payments by year and in the aggregate, for non-cancelable operating leases with initial or remaining terms of one year or more are as follows at December 31, 2017:



	Real Estate Leases		Non-Rental Equipment Leases
2018	$	117	$	43
2019	99		37
2020	77		31
2021	58		22
2022	35		15
Thereafter	39		9
Total	$	425	$	157

Our real estate leases provide for varying terms, including customary escalation clauses. We evaluate our operating leases in accordance with GAAP. Our leases generally include default provisions that are customary, and do not contain material adverse change clauses, cross-default provisions or subjective default provisions. In these leases, the occurrence of an event of default is objectively determinable based on predefined criteria. Based on the facts and circumstances that existed at lease inception and with consideration of our history as a lessee, we believe that it is reasonable to assume that an event of default will not occur.

As discussed in note 2 to the consolidated financial statements (see "New Accounting Pronouncements-Leases"), we expect to adopt updated lease accounting guidance when it becomes effective, on January 1, 2019. Upon adoption of the updated guidance, our operating leases will result in lease assets and lease liabilities being recognized on the balance sheet. While our review of the updated lease accounting guidance is ongoing, we believe that the impact on our balance sheet, while not currently estimable, will be significant.

Rent expense under all non-cancelable real estate, rental equipment and other equipment operating leases totaled $160, $149 and $139 for the years ended December 31, 2017, 2016 and 2015, respectively.

Capital Leases

Capital lease obligations consist primarily of vehicle and building leases with periods expiring at various dates through 2028. Capital lease obligations were $67 and $71 at December 31, 2017 and 2016, respectively. The following table presents capital lease financial statement information for the years ended December 31, 2017, 2016 and 2015, except for balance sheet information, which is presented as of December 31, 2017 and 2016:

Employee Benefit Plans

We currently sponsor a defined contribution 401(k) retirement plan, which is subject to the provisions of the Employee Retirement Income Security Act of 1974. We also sponsor a deferred profit sharing plan for the benefit of the full-time employees of our Canadian subsidiaries. Under these plans, we match a percentage of the participants’ contributions up to a specified amount. Company contributions to the plans were $26, $23 and $22 in the years ended December 31, 2017, 2016 and 2015, respectively.

Environmental Matters

The Company and its operations are subject to various laws and related regulations governing environmental matters. Under such laws, an owner or lessee of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances located on or in, or emanating from, such property, as well as investigation of property damage. We incur ongoing expenses associated with the performance of appropriate remediation at certain locations.
