France24 has a great interview and translation from lawyer, shareholder activist, and blogger Alexei Navalny:

Other Transneft minority shareholders and I were trying to find out what made the construction so expensive when we discovered a truly astonishing document. I’d like to stress that the document was issued by Transneft itself. It’s not an outside analysis or my own guesswork; it’s an official report that was ordered by the Russian Accounts Chamber, signed by Transneft’s first vice-president. We obtained it from an inside source: both Transneft and the Russian Account Chamber have hundreds of employees, and not all of them are corrupt, of course.
