Over several years, Gazprom Investholding and a subsidiary made hundreds of millions of dollars in loans to a company called Kanton Services, according to records from the Panama Papers, the trove of leaked documents from the law firm Mossack Fonseca. Kanton, in turn, owned one of the DST investment vehicles used to buy shares of Facebook. While it is unclear precisely when Kanton first received its stake in the DST entity, Kanton received $197 million of the Gazprom Investholding loans three months before Facebook announced its first deal with Mr. Milner, the records show.
Kanton, based in the British Virgin Islands, had numerous ties to Mr. Milner’s backer, Mr. Usmanov.
