Other than different performance targets, the basic terms of these performance stock units are identical to those granted in January 2008 and February 2009, including using annual return on invested capital (ROIC) as the performance measure. Additionally, a change was made in February 2009 to an underlying assumption used in connection with calculating a component of ROIC. As a result, a lower discount rate (an assumed interest rate) will be used in both the numerator and denominator when calculating the present value of our future operating lease payments to reflect changes to interest rates and our financing costs. This rate will be consistent with the methodology used to calculate our adjusted debt-to-capital ratio. We used this new discount rate to calculate ROIC in connection with determining awards of performance stock units granted in 2009 and 2010. For performance stock units granted in 2008, we will continue calculating ROIC /fontfont style="font-family:Arial;font-size:10pt;"using/fontfont style="font-family:Arial;font-size:10pt;" the methodology and assumptions in effect when the performance stock units were granted. /font/pp style='margin-top:0pt; margin-bottom:0pt'#160;/pp style='margin-top:0pt; margin-bottom:0pt 'font style="font-family:Arial;font-size:10pt;margin-left:0px;"Stock units awarded to selected employees under these grants are subject to continued employment for 37 months and the attainment of certain levels of ROIC./fontfont style="font-family:Arial;font-size:10pt;" We expense the fair value of the units that are probable of being earned based on our forecasted ROIC over the 3-year performance period.

The expected long-term rate of return on plan assets is applied to a calculated value of plan assets that recognizes changes in fair value over a five-year period. This practice is intended to reduce year-to-year volatility in pension expense, but it can have the effect of delaying the recognition of differences between actual returns on assets and expected returns based on long-term rate of return assumptions. Differences in actual experience in relation to assumption s are not recognized in net income immediately, but are deferred and, if necessary, amortized as pension or OPEB expense. /font/pp style='margin-top:0pt;

Cost estimates are based on information available for each site, financial viability of other potentially responsible parties, and existing technology, laws, and regulations.

Estimates of liability may vary over time due to changes in federal, state, and local laws governing environmental remediation.

We are not a party to leveraged derivatives and, by policy, do not use derivative financial instruments for speculative purposes. Derivative financial instruments qualifying for hedge accounting must maintain a specified level of effectiveness between the hedging instrument and the item being hedged, both at inception and throughout the hedged period. We formally document the nature and relationships between the hedging instruments and hedged items at inception, as well as our risk-management objectives, strategies for undertaking the various hedge transactions, and method of assessing hedge effectiveness. Changes in the fair market value of derivative financial instruments that do not qualify for hedge accounting are charged to earnings.

We generally manage the mix of fixed and floating rate de bt through the issuance of targeted amounts of each as debt matures or as we require incremental borrowings. We employ derivatives, primarily swaps, as one of the tools to obtain the targeted mix. In addition, we also obtain flexibility in managing interest costs and the interest rate mix within our debt portfolio by evaluating the issuance of and managing outstanding callable fixed-rate debt securities. /font/pp style='margin-top:0pt; margin-bottom:0pt'#160;/pp style='margin-top:0pt; margin-bottom:0pt'font style="font-family:Arial;font-size:10pt;margin-left:0px;"Swaps allow us to convert debt from fixed rates to variable rates and thereby hedge the risk of changes in the debt's fair value attributable to the changes in interest rates.

Termination of interest rate swap			On February 25, 2010, we elected to terminate an interest rate swap agreement with a notional amount of $250 million prior to the scheduled maturity and received cash of $20 million (which is comprised of $16 million for the fair value of the swap that was terminated and $4 million of accrued but unpaid interest receivable). We designated the swap agreement as a fair value hedge, and as such the unamortized adjustment to debt for the change in fair value of the swap remains classified as debt due after one year in our Condensed Consolidated Statements of Financial Position and will be amortized as a reduction to interest expense through April 15, 2012. As of September 30, 2010, we do not have any interest rate fair value hedges outstanding.
