<p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Duke Energy, Duke Energy Carolinas and Duke Energy Indiana classify their investments as either trading or available-for-sale. Trading securities are reported at fair value in the Condensed Consolidated Balance Sheets with net realized and unrealized gains and losses included in earnings each period. Available-for-sale securities are also reported at fair value on the Condensed Consolidated Balance Sheets with unrealized gains and losses excluded from earnings and reported either as a regulatory asset or liability, as discussed further below, or as a component of other comprehensive income until realized. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Trading Securities. </i>Duke Energy holds investments in debt and equity securities in grantor trusts that are associated with certain deferred compensation plans. These investments are reported at fair value in Duke Energy's Condensed Consolidated Balance Sheets and all realized and unrealized gains and losses are included in earnings each period. At September 30, 2010 and December 31, 2009, the fair value of these investments was $<font class="_mt">38</font> million and $<font class="_mt">33</font> million, respectively. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Available-for-Sale Securities. </i>Investments classified as available-for-sale are comprised of Duke Energy Carolinas' NDTF investments, investments in a grantor trust at Duke Energy Indiana related to other post-retirement benefit plans as required by the IURC, Duke Energy's captive insurance investment portfolio and Duke Energy's and Duke Energy Carolinas' investments in auction rate debt securities. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">All unrealized losses associated with investments in debt and equity securities within Duke Energy Carolinas' NDTF and substantially all unrealized losses associated with Duke Energy Indiana's grantor trust are deferred as a regulatory asset as those operations meet the criteria for regulatory accounting treatment, thus there is no immediate earnings impact as a result of any other-than-temporary impairments that would otherwise be required to be recognized in earnings. For investments held in Duke Energy's captive insurance portfolio and investments in auction rate debt securities held by Duke Energy and Duke Energy Carolinas, unrealized gains and losses are included in other comprehensive income until realized, unless it is determined that the carrying value of an investment is other-than-temporarily impaired, at which time the write-down to fair value may be included in earnings based on the criteria discussed below. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Impairment Analysis.</i> The investments within Duke Energy Carolinas' NDTF and Duke Energy Indiana's grantor trust are managed by independent investment managers with discretion to buy, sell and invest pursuant to the objectives set forth by the trust agreements. Therefore, Duke Energy Carolinas and Duke Energy Indiana have limited oversight of the day-to-day management of these investments. Since day-to-day investment decisions, including buy and sell decisions, are made by the investment manager, the ability to hold investments in unrealized loss positions is outside the control of Duke Energy Carolinas and Duke Energy Indiana. Accordingly, all unrealized losses associated with equity securities within Duke Energy Carolinas' NDTF and Duke Energy Indiana's grantor trust are considered other-than-temporary and are recognized immediately when the fair value of individual investments is less than the cost basis of the investment. However, as discussed above, any other-than-temporary impairments are recorded as a regulatory asset pursuant to regulatory accounting treatment. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Investments in equity securities within Duke Energy's captive insurance portfolio are analyzed each reporting period to determine whether a decline in fair value should be considered other-than-temporary. Criteria used to evaluate whether an impairment associated with equity securities is other-than-temporary includes, but is not limited to, the length of time over which the market value has been lower than the cost basis of the investment, the percentage decline compared to the cost of the investment and management's intent and ability to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value. If a decline in fair value is determined to be other-than-temporary, the investment is written down to its fair value through a charge to earnings. There were no other-than-temporary impairment charges to earnings during the nine months ended September 30, 2010 or 2009. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">With respect to investments in debt securities, if the entity does not have an intent to sell the security and it is not more likely than not that management will be required to sell the debt security before the recovery of its cost basis, the impairment write-down to fair value would be recorded as a component of regulatory assets or other comprehensive income, except for when it is determined that a credit loss exists. In determining whether a credit loss exists, management considers, among other things, the length of time and the extent to which the fair value has been less than the amortized cost basis, changes in the financial condition of the issuer of the security, or in the case of an asset backed security, the financial condition of the underlying loan obligors, ability of the issuer of the security to make scheduled interest or principal payments and any changes to the rating of the security by rating agencies. If it is determined that a credit loss exists, the amount of impairment write-down to fair value would be split between the credit loss, which would be recognized in a regulatory asset or earnings, and the amount attributable to all other factors, which would be recognized as a regulatory asset or within other comprehensive income. Since management believes, based on consideration of the criteria above, that no credit loss exists as of September 30, 2010 and management does not have the intent to sell its investments in auction rate debt securities and the investments in debt securities within its captive insurance portfolio, and it is not more likely than not that management will be required to sell these securities before the anticipated recovery of their cost basis, management concluded that there were no other-than-temporary impairments to earnings necessary as of both September 30, 2010 and 2009. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">See Note 8 for additional information related to fair value measurements for investments in auction rate debt securities. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Management will continue to monitor the carrying value of its entire portfolio of investments in the future to determine if any other-than-temporary impairment losses should be recognized. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Investments in debt and equity securities are classified as either short-term investments or long-term investments based on management's intent and ability to sell these securities, taking into consideration illiquidity factors in the current markets with respect to certain short-term investments that have historically provided for a high degree of liquidity, such as investments in auction rate debt securities. </font></p>

Other trading assets include assets that are carried on the balance sheet at fair value and held for trading purposes. A debt security represents a creditor relationship with an enterprise that is in the form of a security. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt.

<p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Duke Energy, Duke Energy Carolinas and Duke Energy Indiana classify their investments as either trading or available-for-sale. Trading securities are reported at fair value in the Condensed Consolidated Balance Sheets with net realized and unrealized gains and losses included in earnings each period. Available-for-sale securities are also reported at fair value on the Condensed Consolidated Balance Sheets with unrealized gains and losses excluded from earnings and reported either as a regulatory asset or liability, as discussed further below, or as a component of other comprehensive income until realized. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Trading Securities. </i>Duke Energy holds investments in debt and equity securities in grantor trusts that are associated with certain deferred compensation plans. These investments are reported at fair value in Duke Energy's Condensed Consolidated Balance Sheets and all realized and unrealized gains and losses are included in earnings each period. At September 30, 2010 and December 31, 2009, the fair value of these investments was $38 million and $33 million, respectively. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Available-for-Sale Securities. </i>Investments classified as available-for-sale are comprised of Duke Energy Carolinas' NDTF investments, investments in a grantor trust at Duke Energy Indiana related to other post-retirement benefit plans as required by the IURC, Duke Energy's captive insurance investment portfolio and Duke Energy's and Duke Energy Carolinas' investments in auction rate debt securities. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">All unrealized losses associated with investments in debt and equity securities within Duke Energy Carolinas' NDTF and substantially all unrealized losses associated with Duke Energy Indiana's grantor trust are deferred as a regulatory asset as those operations meet the criteria for regulatory accounting treatment, thus there is no immediate earnings impact as a result of any other-than-temporary impairments that would otherwise be required to be recognized in earnings. For investments held in Duke Energy's captive insurance portfolio and investments in auction rate debt securities held by Duke Energy and Duke Energy Carolinas, unrealized gains and losses are included in other comprehensive income until realized, unless it is determined that the carrying value of an investment is other-than-temporarily impaired, at which time the write-down to fair value may be included in earnings based on the criteria discussed below. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Impairment Analysis.</i> The investments within Duke Energy Carolinas' NDTF and Duke Energy Indiana's grantor trust are managed by independent investment managers with discretion to buy, sell and invest pursuant to the objectives set forth by the trust agreements. Therefore, Duke Energy Carolinas and Duke Energy Indiana have limited oversight of the day-to-day management of these investments. Since day-to-day investment decisions, including buy and sell decisions, are made by the investment manager, the ability to hold investments in unrealized loss positions is outside the control of Duke Energy Carolinas and Duke Energy Indiana. Accordingly, all unrealized losses associated with equity securities within Duke Energy Carolinas' NDTF and Duke Energy Indiana's grantor trust are considered other-than-temporary and are recognized immediately when the fair value of individual investments is less than the cost basis of the investment. However, as discussed above, any other-than-temporary impairments are recorded as a regulatory asset pursuant to regulatory accounting treatment. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Investments in equity securities within Duke Energy's captive insurance portfolio are analyzed each reporting period to determine whether a decline in fair value should be considered other-than-temporary. Criteria used to evaluate whether an impairment associated with equity securities is other-than-temporary includes, but is not limited to, the length of time over which the market value has been lower than the cost basis of the investment, the percentage decline compared to the cost of the investment and management's intent and ability to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value. If a decline in fair value is determined to be other-than-temporary, the investment is written down to its fair value through a charge to earnings. There were no other-than-temporary impairment charges to earnings during the nine months ended September 30, 2010 or 2009. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">With respect to investments in debt securities, if the entity does not have an intent to sell the security and it is not more likely than not that management will be required to sell the debt security before the recovery of its cost basis, the impairment write-down to fair value would be recorded as a component of regulatory assets or other comprehensive income, except for when it is determined that a credit loss exists. In determining whether a credit loss exists, management considers, among other things, the length of time and the extent to which the fair value has been less than the amortized cost basis, changes in the financial condition of the issuer of the security, or in the case of an asset backed security, the financial condition of the underlying loan obligors, ability of the issuer of the security to make scheduled interest or principal payments and any changes to the rating of the security by rating agencies. If it is determined that a credit loss exists, the amount of impairment write-down to fair value would be split between the credit loss, which would be recognized in a regulatory asset or earnings, and the amount attributable to all other factors, which would be recognized as a regulatory asset or within other comprehensive income. Since management believes, based on consideration of the criteria above, that no credit loss exists as of September 30, 2010 and management does not have the intent to sell its investments in auction rate debt securities and the investments in debt securities within its captive insurance portfolio, and it is not more likely than not that management will be required to sell these securities before the anticipated recovery of their cost basis, management concluded that there were no other-than-temporary impairments to earnings necessary as of both September 30, 2010 and 2009. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">See Note 8 for additional information related to fair value measurements for investments in auction rate debt securities. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Management will continue to monitor the carrying value of its entire portfolio of investments in the future to determine if any other-than-temporary impairment losses should be recognized. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Investments in debt and equity securities are classified as either short-term investments or long-term investments based on management's intent and ability to sell these securities, taking into consideration illiquidity factors in the current markets with respect to certain short-term investments that have historically provided for a high degree of liquidity, such as investments in auction rate debt securities. </font></p>

<p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Duke Energy, Duke Energy Carolinas and Duke Energy Indiana classify their investments as either trading or available-for-sale. Trading securities are reported at fair value in the Condensed Consolidated Balance Sheets with net realized and unrealized gains and losses included in earnings each period. Available-for-sale securities are also reported at fair value on the Condensed Consolidated Balance Sheets with unrealized gains and losses excluded from earnings and reported either as a regulatory asset or liability, as discussed further below, or as a component of other comprehensive income until realized. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Trading Securities. </i>Duke Energy holds investments in debt and equity securities in grantor trusts that are associated with certain deferred compensation plans. These investments are reported at fair value in Duke Energy's Condensed Consolidated Balance Sheets and all realized and unrealized gains and losses are included in earnings each period. At September 30, 2010 and December 31, 2009, the fair value of these investments was $38 million and $33 million, respectively. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Available-for-Sale Securities. </i>Investments classified as available-for-sale are comprised of Duke Energy Carolinas' NDTF investments, investments in a grantor trust at Duke Energy Indiana related to other post-retirement benefit plans as required by the IURC, Duke Energy's captive insurance investment portfolio and Duke Energy's and Duke Energy Carolinas' investments in auction rate debt securities. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">All unrealized losses associated with investments in debt and equity securities within Duke Energy Carolinas' NDTF and substantially all unrealized losses associated with Duke Energy Indiana's grantor trust are deferred as a regulatory asset as those operations meet the criteria for regulatory accounting treatment, thus there is no immediate earnings impact as a result of any other-than-temporary impairments that would otherwise be required to be recognized in earnings. For investments held in Duke Energy's captive insurance portfolio and investments in auction rate debt securities held by Duke Energy and Duke Energy Carolinas, unrealized gains and losses are included in other comprehensive income until realized, unless it is determined that the carrying value of an investment is other-than-temporarily impaired, at which time the write-down to fair value may be included in earnings based on the criteria discussed below. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2"><i>Impairment Analysis.</i> The investments within Duke Energy Carolinas' NDTF and Duke Energy Indiana's grantor trust are managed by independent investment managers with discretion to buy, sell and invest pursuant to the objectives set forth by the trust agreements. Therefore, Duke Energy Carolinas and Duke Energy Indiana have limited oversight of the day-to-day management of these investments. Since day-to-day investment decisions, including buy and sell decisions, are made by the investment manager, the ability to hold investments in unrealized loss positions is outside the control of Duke Energy Carolinas and Duke Energy Indiana. Accordingly, all unrealized losses associated with equity securities within Duke Energy Carolinas' NDTF and Duke Energy Indiana's grantor trust are considered other-than-temporary and are recognized immediately when the fair value of individual investments is less than the cost basis of the investment. However, as discussed above, any other-than-temporary impairments are recorded as a regulatory asset pursuant to regulatory accounting treatment. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Investments in equity securities within Duke Energy's captive insurance portfolio are analyzed each reporting period to determine whether a decline in fair value should be considered other-than-temporary. Criteria used to evaluate whether an impairment associated with equity securities is other-than-temporary includes, but is not limited to, the length of time over which the market value has been lower than the cost basis of the investment, the percentage decline compared to the cost of the investment and management's intent and ability to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value. If a decline in fair value is determined to be other-than-temporary, the investment is written down to its fair value through a charge to earnings. There were no other-than-temporary impairment charges to earnings during the nine months ended September 30, 2010 or 2009. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">With respect to investments in debt securities, if the entity does not have an intent to sell the security and it is not more likely than not that management will be required to sell the debt security before the recovery of its cost basis, the impairment write-down to fair value would be recorded as a component of regulatory assets or other comprehensive income, except for when it is determined that a credit loss exists. In determining whether a credit loss exists, management considers, among other things, the length of time and the extent to which the fair value has been less than the amortized cost basis, changes in the financial condition of the issuer of the security, or in the case of an asset backed security, the financial condition of the underlying loan obligors, ability of the issuer of the security to make scheduled interest or principal payments and any changes to the rating of the security by rating agencies. If it is determined that a credit loss exists, the amount of impairment write-down to fair value would be split between the credit loss, which would be recognized in a regulatory asset or earnings, and the amount attributable to all other factors, which would be recognized as a regulatory asset or within other comprehensive income. Since management believes, based on consideration of the criteria above, that no credit loss exists as of September 30, 2010 and management does not have the intent to sell its investments in auction rate debt securities and the investments in debt securities within its captive insurance portfolio, and it is not more likely than not that management will be required to sell these securities before the anticipated recovery of their cost basis, management concluded that there were no other-than-temporary impairments to earnings necessary as of both September 30, 2010 and 2009. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">See Note 8 for additional information related to fair value measurements for investments in auction rate debt securities. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Management will continue to monitor the carrying value of its entire portfolio of investments in the future to determine if any other-than-temporary impairment losses should be recognized. </font></p>
<p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"><font style="font-family: Times New Roman;" class="_mt" size="2">Investments in debt and equity securities are classified as either short-term investments or long-term investments based on management's intent and ability to sell these securities, taking into consideration illiquidity factors in the current markets with respect to certain short-term investments that have historically provided for a high degree of liquidity, such as investments in auction rate debt securities. </font></p>
