Investment Strategy The Company’s global pension and postretirement funds’ investment strategy is to invest in a prudent manner for the exclusive purpose of providing benefits to participants.
The investment strategies are targeted to produce a total return that, when combined with the Company’s contributions to the funds, will maintain the funds’ ability to meet all required benefit obligations.
Risk is controlled through diversification of asset types and investments in domestic and international equities, fixed income securities and cash and short-term investments.
The target asset allocation in most locations outside the U. S.  is primarily in equity and debt securities.
These allocations may vary by geographic region and country depending on the nature of applicable obligations and various other regional considerations.
The wide variation in the actual range of plan asset allocations for the funded non-U.
S.  plans is a result of differing local statutory requirements and economic conditions.
For example, in certain countries local law requires that all pension plan assets must be invested in fixed income investments, government funds or local-country securities.
Significant Concentrations of Risk in Plan Assets The assets of the Company’s pension plans are diversified to limit the impact of any individual investment.
The U. S.  qualified pension plan is diversified across multiple asset classes, with publicly traded fixed income, hedge funds, publicly traded equity and real estate representing the most significant asset allocations.
Investments in these four asset classes are further diversified across funds, managers, strategies, vintages, sectors and geographies, depending on the specific characteristics of each asset class.
The pension assets for the Company’s non-U.
S.  Significant Plans are primarily invested in publicly traded fixed income and publicly traded equity securities.
Oversight and Risk Management Practices The framework for the Company’s pension oversight process includes monitoring of retirement plans by plan fiduciaries and/or management at the global, regional or country level, as appropriate.
Independent Risk Management contributes to the risk oversight and monitoring for the Company’s U. S.  qualified pension plan and non-U.
