On June 30, 2011, the spin-off of Marathon's downstream business was
completed, creating two independent energy companies: Marathon Oil and MPC.
Marathon stockholders at the close of business on the record date of June 27,
2011 received one share of MPC common stock for every two shares of Marathon
common stock held. A private letter ruling received in June 2011 from the IRS
affirmed the tax-free nature of the spin-off.
