(8) Commitments and Contingencies

Leases

Skyhook leases various properties under operating leases expiring at various times through 2018. Skyhook’s two principal facilities are under lease through December 2017 and December 2019, respectively. Including amounts due to Liberty under the facilities sharing agreement, the Company’s total rental expense was $275 thousand and $304 thousand for each of the three months ended June 30, 2017 and 2016, respectively, and $522 thousand and $555 thousand for each of the six months ended June 30, 2017 and 2016, respectively.

General Litigation

In the ordinary course of business, the Company and its consolidated subsidiary are parties to legal proceedings and claims involving alleged infringement of third-party intellectual property rights, defamation, and other claims, including infringement of the intellectual property rights of the Company and its consolidated subsidiary by third parties. Although it is reasonably possible that the Company may incur losses upon conclusion of such matters, an estimate of any loss or range of loss cannot be made. In the opinion of management, it is expected that amounts, if any, which may be required to satisfy such contingencies will not be material in relation to the accompanying condensed consolidated financial statements.

Indemnification Claims

In the normal course of business, Skyhook provides indemnification to certain customers against specified claims that might arise against those customers from the use of Skyhook’s products. To date, Skyhook has not made any significant reimbursements to any of its customers for any losses related to these indemnification provisions. However, four such claims are currently pending. Skyhook is unable to estimate the maximum potential impact of these indemnification provisions on its future results of operations, although Skyhook’s liabilities in certain of those arrangements are customarily limited in various respects, including monetarily. Accordingly, no accrual was recorded related to indemnification claims as of June 30, 2017 or December 31, 2016.

Certain Risks and Concentrations

The Skyhook business is subject to certain risks and concentrations including dependence on relationships with its customers. The Company’s largest customers, that accounted for greater than 10% of revenue, aggregated 61% and 61% of total revenue for the three months ended June 30, 2017 and 2016, respectively, and 58% and 68% of total revenue for the six months ended June 30, 2017 and 2016, respectively.

Off-Balance Sheet Arrangements

Liberty Broadband did not have any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on the Company’s financial condition, results of operations, liquidity, capital expenditures or capital resources.
