Commitments and Contingencies

Commitments and Contingencies

The Company is involved in various claims, lawsuits or proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such matters, and it is impossible to presently determine the ultimate costs or losses that may be incurred, if any, management believes the resolution of such uncertainties and the incurrence of such costs should not have a material adverse effect on the Company's consolidated financial position or results of operations. See note 11 for a discussion of the operating lease commitments. In addition, see note 1 for a discussion of the CCIC's option to purchase approximately 68% of the Company's towers at the end of their respective lease terms. CCIC has no obligation to exercise the purchase option.

Asset Retirement Obligations

Pursuant to its ground lease and easement agreements, the Company has the obligation to perform certain asset retirement activities, including requirements upon contract termination to remove sites or remediate the land upon which site resides. Accretion expense related to liabilities for retirement obligations amounted to $0.5 million, $0.8 million, and $0.7 million for the years ended December 31, 2019, 2018 and 2017, respectively. As of December 31, 2019 and 2018, liabilities for retirement obligations amounted to $11.4 million and $10.9 million, respectively, representing the net present value of the estimated expected future cash outlay. As of December 31, 2019, the estimated undiscounted future cash outlay for asset retirement obligations was approximately $82.6 million. See note 3.
