Ukraine's President Petro Poroshenko has stressed that he transferred the management of his business assets to consulting and law firms and is expecting these organizations to provide explanations to Ukrainian and foreign media in response to their queries.

"On becoming president, I moved away from managing the assets, having entrusted this business to appropriate consulting and law companies. I expect them to provide exhaustive explanations for the Ukrainian and international press," reads a statement published on Poroshenko's official Facebook account on Monday.

Talking about declaring of his incomes, expenses and liabilities of a financial character, the head of Ukrainian state stressed that he took seriously official declaration of his income, expenses and liabilities of a financial character.

"I'm the first official in Ukraine, who has a serious attitude towards declaring of his assets, tax payment and the issue of the conflict of interests, which I settle under the Ukrainian legislation and international private law," he said.

According to an investigation by Ukrainian journalist Anna Babinets as part of the Organized Crime and Corruption Reporting Project (OCCRP), which was made public on the Hromadske TV channel, Ukrainian President Petro Poroshenko did not mentioned in his declaration of income, expenses and financial obligations for 2014 that he had established a company in the British Virgin Islands.

When asked why this company was not included into Poroshenko's income declaration, Makar Paseniuk, managing director of ICU investment company, who is authorized by the Ukrainian presidential administration to communicate with media in the matters related to Poroshenko's business affairs, said the shares of the Prime Asset Partners Limited have no par value. In accordance with the requirements for the declaration of incomes and property as of 2014, only the shares which had some nominal value needed to be included in the declaration, he added.

However, the documents obtained by OCCRP show that starting from the registration date of August 21, 2014, Prime Asset Partners Ltd.'s shares had a total value of $1,000 and Poroshenko was listed as the sole shareholder. However, in his declaration for 2014, the president left a blank space in the section 'contributions to the charter capital of the company, including those abroad.'

Meanwhile, Paseniuk said that there was more than one offshore company.

"Prime Asset Partners Limited was founded in the summer of 2014 in the course of corporate restructuring, which was a preparatory stage for the further sale of the Roshen Group. After its establishment, the company has not carried out any activities other than those mentioned below. In the fall of 2014, Prime Asset Partners Limited established CEE Confectionery Investments Limited in Cyprus, which in turn founded the Roshen Europe BV company in the Netherlands," the report says.

Poroshenko's legal advisers justify the creation of such a group of companies by the president. They say this was done "in keeping with the market practice in Ukraine for the companies which are to be sold to strategic investors."

According to editor for the Organized Crime and Corruption Reporting Program Drew Sullivan, the information about Poroshenko's offshore companies are part of the Panama Papers, which are the documents obtained from a Panama-based offshore services provider.

Roshen Corporation includes confectionery factories in Kyiv, Kremenchuk and Vinnytsia, and the dairy producer Bershadmoloko. It also runs confectionary facilities in Klaipeda (Lithuania), Lipetsk ( Russia), and Bonbonetti Choco (Hungary).

Poroshenko in January 2016 stated he signed a contract, according to which he transferred his stake in Roshen Corporation to an independent "blind" trust."
