But it said the period under investigation was 2010-2012, and noted that this was before the company hired Hunter Biden.
“Changes to the board of Burisma Limited, which are currently the object of international attention, took place only in May 2014, and therefore are not and never were the subject of (the anti-corruption bureau’s) investigation,” the bureau’s statement said.
Hunter Biden was a director on Burisma’s board from 2014-2018, according to documents filed by the company in Cyprus, where it is registered.
The investigation into Burisma covers a period when Ukraine was governed by a Kremlin ally, Viktor Yanukovich. Burisma hired Hunter Biden after Yanukovich was toppled in a popular revolt in 2014 and replaced by a pro-Western government.
At the time, many Ukrainian firms were seeking to distance themselves from their relationships with the previous, pro-Moscow authorities, and some invited Western public figures to sit on their boards.
The NABU’s investigation related to the 2010-2012 period is not particularly active, Kholodnytsky added.
A Ukrainian investigation of gas company Burisma is focused solely on activity that took place before Hunter Biden, son of former U.S. Vice President Joe Biden, was hired to sit on its board, Ukraine's anti-corruption investigation agency said.
