National joint-stock company Naftogaz Ukrainy after making internal inquiries has not revealed violation of internal regulations of the holding or any conflicts of interest involving employees who were associated with offshore companies.

The press service said that Deputy Board Chairman Serhiy Konovets is a minority co-owner of Kvassir Global Inc. registered in British Virgin Islands in 2009 when he lived and officially worked outside Ukraine. The operations of the companies incorporated in the group are linked to production of pet litters.

The operations of Kvassir Global Inc. are not associated with the operation of Konovets in Naftogaz. The company did not buy or supply goods or services to companies incorporated in Naftogaz Ukrainy or any other oil and gas companies in Ukraine. Investment in Kvassir Global Inc. is reflected in Konovets' declaration from the moment when he returned to Ukraine. The co-owners of the company are several Ukrainian and foreign investors who are not affiliated with Naftogaz group. They were not civil servants and were not involved in politics.

Board Chairman of public joint-stock company Ukrtransnafta Mykola Havrylenko was mentioned as the co-owner of Turitella registered in 1999 in Panama. In 2007 he left Turitella as a shareholder and since then he has no relation to the company.

"The company continues analyzing the list of persons mentioned in the Panama Papers and will inform on the results," Naftogaz said.
