Ukrainian President Petro Poroshenko controls more than 100 companies registered in Ukraine and in foreign jurisdictions, according to his electronic declaration of earnings and assets, filed to a new national system of income declaration.

Poroshenko's declaration was sent one hour before the deadline for submissions to the system, which was implemented under pressure by International Monetary Fund as a means of eradicating corruption among state officials, including those in high office.

Faltering introduction of the electronic system this year was a main obstacle to the resumption of the IMF's $17.5bn stalled support package for Ukraine, and also held up work on the long-negotiated granting of visa-free travel for Ukrainians to the European Union (EU). Since the system was brought fully online in September, the IMF released another $1bn tranche of funding that has been withheld for more than a year.

"As for my e-declaration, I’d like to note straight away that all the valuable movable and immovable property: housing, estates, cars, paintings, women's jewelry - all had been purchased (not leased) before my presidency," Poroshenk wrote on his Facebook page on October 30. "In addition, the property was mainly acquired when I was not a public servant."

According to the declaration, the president controls non-diversified corporate investment fund Prime Assets Capital, which is an umbrella for numerous assets belonging to Poroshenko.

Among Ukraine-registered companies, Poroshenko is a beneficiary owner of Roshen Europe B.V. (the Netherlands), Bonbonetti Choco Confectionary Factory, Bonbonetti, Choco Bonita (Hungary), ROSHEN (Lithuania), Roshen Food (Shanghai), Lipetsk Confectionary Factory and RoshenTrans (Russia), Roshen-Polska (Poland), Feruvita S.L. and Centris (Spain), Eray-System, Telaview and CII Confectionary Investments (Cyprus), Prime Assets Partners (British Virgin Islands).

Poroshenko also declared his revenue from interest was UAH12.3mn ($481,900) and investment revenue totalled UAH59.2mn ($2.3mn) in 2015.The president has UAH540,000 ($21,155), $26.3mn and €14,300 in bank accounts, as well as UAH900,000 ($35,260) and $60,000 in cash.

Meanwhile, according to the declaration of Prime Minister Volodymyr Groysman filed five days earlier, he has UAH2.4mn ($93,660), $870,000 and €460,000 in non-deposit cash. The PM also has deposits of UAH2.1mn ($82,380) in Credit Agricole Bank, UAH21,775 ($854) and €16,200 in Privatbank, and UAH3,499 ($137) in Prominvestbank. The premier also owns two apartments, two houses and four land parcels, as well as 20 declared works of art, mainly watches and jewelry.

Earlier, the president's son Oleksiy Poroshenko, a Ukrainian lawmaker, declared more than UAH77,000 ($3,000) of salary for 2015, and almost UAH81,000 ($3,170) as financing expenses related to his parliamentary activities. At the same time, the salary of his wife, Yulia Poroshenko, was more than UAH1.96mn ($76,800).

Oleksiy also declared €15,000 on bank accounts, as well as UAH187,000 ($7,330), $141,000 and €88,000 in cash.
