The amounts in the table above exclude $212.0 million of income tax related uncertain tax positions, as the Company is unable to reasonably estimate the ultimate amount or time of settlement of those liabilities.

Verisign enters into certain purchase obligations with various vendors. The Company’s significant purchase obligations include firm commitments with telecommunication carriers and other service providers. The Company does not have any significant purchase obligations beyond 2019.

The Company has an agreement with Internet Corporation for Assigned Name and Numbers (“ICANN”) to be the sole registry operator for domain names in the .com registry through November 30, 2024. Under this agreement, the Company pays ICANN on a quarterly basis, $0.25 for each annual increment of a domain name registered or renewed during such quarter. As of December 31, 2016, there were 126.9 million domain names in the .com registry. However, the number of domain names registered and renewed each quarter may vary significantly. The Company incurred registry fees for the .com registry of $31.5 million in 2016, $30.9 million in 2015, and $28.4 million in 2014. Registry fees for other top-level domains that we operate have been excluded from the table above because the amounts are variable or passed through to registrars.

The Company has an agreement with the Government of Tuvalu to be the sole registry operator for .tv domain names through December 31, 2021. Registry fees were $5.0 million in 2016 and 2015, and $4.5 million in 2014.

Verisign leases a small portion of its facilities under operating leases that extend into 2020. Rental expenses under operating leases were not material in any period presented. Future rental expenses under existing operating leases are not material.

Off-Balance Sheet Arrangements

As of December 31, 2016 and 2015, the Company did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, the Company is not exposed to any financing, liquidity, market or credit risk that could arise if the Company had engaged in such relationships.

It is not the Company’s business practice to enter into off-balance sheet arrangements. However, in the normal course of business, the Company does enter into contracts in which it makes representations and warranties that guarantee the performance of the Company’s products and services. Historically, there have been no significant losses related to such guarantees.
