Set forth in Footnote 1 on page 39 and Exhibit A to the CD&A is a full description of how non-GAAP EPS was determined. The Company believes non-GAAP EPS is a very important measure to investors and which is indicative of Company performance; accordingly, it represents a significant factor in determining both annual and long term executive compensation. To calculate CAP for our PEOs and Non-PEO NEOs in the table above, the following amounts were deducted and added to the values as reported in the SCT:

For the periods covered, no individual equity awards were granted and vested in the same year and no dividends or other earnings were paid on outstanding and unvested awards. The valuation assumptions used to calculate the fair values of performance shares reflect the probable outcome of the performance conditions as of the applicable measuring date (or actual performance results approved by the Compensation Committee as of the applicable vesting date). Outstanding RSUs accrue dividend equivalent units in the form of additional common shares that are not distributed unless and until the underlying award vests and becomes payable. The value of dividend equivalent units is reflected in the values set forth above.

(a)
The total pension benefit adjustments for each applicable year include the aggregate of two components: (i) the actuarially determined service cost for services rendered by the PEO and non-PEO NEOs during the applicable year (the “service cost”); and (ii) the entire cost of benefits granted in a plan amendment (or initiation) during the applicable year that are attributed by the benefit formula to services rendered in periods prior to the plan amendment or initiation (the “prior service cost”), in each case, calculated in accordance with U.S. GAAP

(b)
For the periods covered, no individual equity awards were granted and vested in the same year and no dividends or other earnings were paid on outstanding and unvested awards. The valuation assumptions used to calculate the fair values of performance shares reflect the probable outcome of the performance conditions as of the applicable measuring date (or actual performance results approved by the Compensation Committee as of the applicable vesting date). Outstanding RSUs accrue dividend equivalent units in the form of additional common shares that are not distributed unless and until the underlying award vests and becomes payable. The value of dividend equivalent units is reflected in the values set forth above.

(4)
Set forth in Footnote 1 on page 39 and Exhibit A to the CD&A is a full description of how non-GAAP EPS was determined. The Company believes non-GAAP EPS is a very important measure to investors and which is indicative of Company performance; accordingly, it represents a significant factor in determining both annual and long term executive compensation.
