Commitments and Contingencies

Operating Leases

We lease two facilities in Denver, CO and Oxnard, CA that are under operating leases through December 2018 and March 2020, respectively. Both of these leases require us to pay increases in real estate taxes, operating costs and repairs over certain base year amounts. Rent expense for the three and six months ended June 30, 2017 were $74,000 and $147,000, respectively. Rent expense for the three and six months ended June 30, 2016 were $72,000 and $146,000, respectively.

Future minimum rental commitments under all non-cancelable operating leases as of June 30, 2017, are as follows (in thousands):



Year Ending December 31,
Remaining 2017	$	151
2018	308
2019	88
2020	23
	$	570

Commercial Commitments

We have entered into a number of agreements with our suppliers to purchase communications and consulting services. Some of the agreements require a minimum amount of services to be purchased over the life of the agreement, or during a specified period of time. Glowpoint believes that it will meet its commercial commitments. Historically, in certain instances where Glowpoint did not meet the minimum commitments, no penalties for minimum commitments have been assessed and the Company has entered into new agreements. It has been our experience that the prices and terms of successor agreements are similar to those offered by other suppliers. Glowpoint does not believe that any loss contingency related to a potential shortfall should be recorded in the consolidated financial statements because it is not probable, from the information available and from prior experience, that Glowpoint has incurred a liability.

Letters of Credit

As of June 30, 2017, the Company had an outstanding irrevocable standby letter of credit with Wells Fargo Bank, N.A., for $18,000 to serve as our security deposit for our lease of office space in Colorado. See Note 4.
