Effect of 1% change in assumed health care cost trend rates
The assumed health care cost trend rate used in measuring the postretirement benefit obligation for retirees for 2013 is 9.00%, grading down to 5.00% in the year 2021 and thereafter.  The assumed health care cost trend rates have a significant effect on the amounts reported for other postretirement benefits.  A 1% change in the assumed health care cost trend rate would have the following effects:

Fair value of plan assets by level of the fair value hierarchy
The following tables present the fair value of our plan assets by level of the fair value hierarchy.  In accordance with the FASB’s guidance for fair value measurements, level 1 inputs are quoted prices in active markets for identical assets; level 2 inputs are significant other observable inputs; and level 3 inputs are significant unobservable inputs.

Percent of total portfolio
We employ a dynamic investment strategy, changing the allocation between return-seeking and liability hedging assets to de-risk the plan as the funded ratio improves. We believe the strategy provides a reasonable probability of achieving growth of assets that will assist in closing the Plan’s funding gap, while removing risk systematically as we reach our long-term goal of being fully-funded.  Based on an assessment of our long-term goals and desired risk levels, we developed a glide path that adjusts the target allocation to return-seeking assets as well as the corresponding minimum and maximum allocations as the Plan’s funded status improves.  The funded status is monitored on a quarterly basis.  We seek to maintain a diversified portfolio within the return-seeking asset portfolio and the liability hedging portfolio using a diversified blend of equity and debt investments.  The return-seeking component is diversified across U.S. and non-U.S. stocks, both actively and passively managed.  The liability hedging component is diversified across the maturity, quality and sector spectrum. To achieve an appropriate level of expected return, value-added potential, and risk, we adopted the following target allocations within the return-seeking segment:
