Other non-current assets—On March 20, 2014, the United States imposed sanctions on Bank Rossiya, a Russian open joint stock company, and Bank Rossiya was placed on the Specially Designated Nationals ("SDN") and Blocked Persons List of the U.S. Department of the Treasury, Office of Foreign Assets Control ("OFAC"). On April 28, 2014, LLC IC Abros, a holding company related to Bank Rossiya, was also designated an SDN. More than 50% of the voting capital of Telcrest Investments Limited ("Telcrest"), one of the Company's principal stockholders, is beneficially owned, directly or indirectly, by Bank Rossiya and LLC IC Abros, and therefore Telcrest is also considered to be a target of sanctions.

On March 5, 2014, April 29, 2014, July 25, 2014 and October 27, 2014, the Company's Board declared a dividend to stockholders. The Company paid the declared dividends on March 28, 2014, June 26, 2014, September 25, 2014 and December 23, 2014, however, dividends totaling $27,684 otherwise payable to Telcrest were blocked pursuant to the U.S. sanctions described above and paid into a separate interest-bearing bank account for the benefit of Telcrest, but to which Telcrest will not have access while either Bank Rossiya or LLC IC Abros remain an SDN.
