<div align="left" style="font-size: 10pt; margin-top: 6pt">     Other comprehensive income refers to revenues, expenses, gains and losses that under generally
accepted accounting principles are included in comprehensive income, a component of Stockholders’
Equity within the Consolidated Balance Sheets, rather than net income on the Consolidated
Statements of Income. Under existing accounting standards, other comprehensive income may include,
among other things, unrecognized gains and losses and prior service cost related to pension and
other postretirement benefit plans and accounting for derivative financial instruments, which
qualify for cash flow hedge accounting.
