Leak reveals Rex Tillerson is director of Bahamas-based US-Russian oil company

Documents from tax haven will raise more questions over suitability of Donald Trump’s pick for US secretary of state

 Rex Tillerson, the businessman nominated by Donald Trump to be the next US secretary of state, is the long-time director of a US-Russian oil firm based in the tax haven of the Bahamas, leaked documents show.

Tillerson – the chief executive of ExxonMobil – has been a director of the oil company’s Russian subsidiary, Exxon Neftegas, since 1998. His name – RW Tillerson – appears next to other officers who are based at Houston, Texas; Moscow; and Sakhalin, in Russia’s far east.

ExxonMobil’s use of offshore regimes – while legal – may also jar with Trump’s avowal to put “America first”.

.. It is widely assumed by investors that the new Trump administration will drop sanctions. This would allow the Kara joint venture to resume, boosting Exxon’s share price and yielding potential profits in the tens of billions of dollars. According to company records, Tillerson currently owns $218m of stock. His Exxon pension is worth about $70m.

.. Rubio praised him as a “respected businessman” but said that the next secretary of state “must be someone who views the world with moral clarity [and who] has a clear sense of America’s interests”.

.. The Bahamas is notorious for secrecy and has a corporate tax rate of zero.

.. The firm was one of the largest taxpayers in the world, with an effective global tax rate in 2015 of 34%, it said. Its effective tax rate over the past three years – 2013, 2014, 2015 – was 43%, it added. This compared favourably with other Fortune 100 companies, which “have substantially lower effective tax rates than ExxonMobil”.
