The Company maintains an investment policy for the management of the Company Plan’s assets. The objective of this policy is to build a portfolio designed to achieve a balance between investment return and asset protection by investing in equities of high quality companies and in high quality fixed income securities which are broadly balanced and represent all market sectors. The target allocations for plan assets are 50% equity securities, 45% fixed income securities and 5% in other assets. Equity securities primarily include investments in large-cap, mid-cap and small-cap companies located in the United States and to a lesser extent international equities in developed and emerging countries. Fixed income securities primarily include U.S. Treasury securities, mortgage-backed bonds and corporate bonds of companies from diversified industries. Other assets include investments in commodities. The weighted average expected long-term rate of return for the Company Plan’s assets is as follows:

	Target Allocation		Weighted Average Expected Long-Term Rate of Return
Equity securities	50.0	%	4.5	%
Fixed income securities	45.0	%	2.3	%
Other assets	5.0	%	0.5	%
