Pension and Other Benefit Programs

In connection with the Company’s acquisition of NYSE on November 13, 2013 (Note 3), the Company assumed NYSE’s pension plans covering its U.S. and certain European operations, as well as other benefit plans. Following the Euronext IPO in June 2014, there are no longer any NYSE European operations covered by the pension or benefit plans (Note 13). The following table provides the components of net periodic expense (benefit) associated with the pension plans, the supplemental executive retirement ("SERP") plans and the post-retirement benefit plans for the six months and three months ended June 30, 2014 in the accompanying consolidated statements of income (in millions):

During the six months ended June 30, 2014, the Company contributed $8 million to its pensions plans. Based on current actuarial assumptions, the Company anticipates funding an additional $43 million to its pension plans during the second half of 2014.
