Defined benefit plan investment goals	The asset allocation policy for the U.S. Pension Plans and U.S. retiree healthcare plan was developed in consideration of the following long-term investment objectives: achieving a return on assets consistent with the investment policy, achieving portfolio returns which exceed the average return for similarly invested funds and maximizing portfolio returns with at least a return of 2.5% above the one-year constant maturity Treasury bond yield over reasonable measurement periods and based on reasonable market cycles.
Defined benefit plan diversification	The Company targets a 20% allocation of its U.S. retirement plans’ equity portfolio to be invested in financial markets outside of the United States.
