(a)

The increase in net periodic benefit costs in the first six months of 2011, compared to the first six months of 2010, for our U.S. qualified plans was primarily driven by higher settlement charges and lower curtailment gains associated with Wyeth-related restructuring initiatives partially offset by higher expected return on plan assets and special termination benefits recognized in the prior-year period for certain executives as part of Wyeth-related restructuring initiatives.

(b)

The decrease in net periodic benefit costs in the first six months of 2011, compared to the first six months of 2010, for our U.S. supplemental (non-qualified) pension plans was primarily driven by special termination benefits recognized in the prior-year period for certain executives as part of Wyeth-related restructuring initiatives.

(c)	The increase in net periodic benefit costs in the first six months of 2011, compared to the first six months of 2010. for our international pension plans was primarily driven by the decrease in the discount rate partially offset by higher expected return on plan assets.

(d)

The decrease in net periodic benefit costs in the first six months of 2011, compared to the first six months of 2010, for our postretirement plans was primarily driven by the harmonization of the postretirement plans and by higher curtailment gains and lower settlement charges associated with Wyeth-related restructuring initiatives.
