In February 2009, SCE&G was granted accounting orders by the SCPSC which allowed it to mitigate a significant portion of<br />

increased pension cost by deferring as a regulatory asset the amount of pension cost above that which was included in then current<br />

cost of service rates for its retail electric and gas distribution regulated operations. In July 20<strong>10</strong>, upon the new retail electric base rates<br />

becoming effective, SCE&G began deferring, as a regulatory asset, all pension cost related to its regulated retail electric operations<br />

that otherwise would have been charged to expense. In November 20<strong>10</strong>, upon the updated gas rates becoming effective under the<br />

RSA, SCE&G began deferring, as a regulatory asset, all pension cost related to its regulated natural gas operations that otherwise<br />

would have been charged to expense.<br />
