In connection with the separation of the Downstream business on April 30, 2012, ConocoPhillips entered into an Employee Matters Agreement with Phillips 66 which provides that employees of Phillips 66 will no longer participate in benefit plans sponsored or maintained by ConocoPhillips upon separation. As such, changes in net periodic benefit cost included in the table above primarily relate to the employees of Phillips 66 no longer participating in the ConocoPhillips benefit plans for the three- and six-month period s ended June 30, 2013. During the first six months of 2013, we contributed $132 million to our domestic benefit plans and $96 million to our international benefit plans.
