Trading securities |  | ¥ | 49,596 |  |  | ¥ | 71,991 |  |  | $ | 866 |
Available-for-sale securities |  |  | 845,234 |  |  |  | 883,410 |  |  |  | 10,624 |
Held-to-maturity securities |  |  | 43,732 |  |  |  | 43,695 |  |  |  | 526 |

Total |  | ¥ | 1,104,158 |  |  | ¥ | 1,175,381 |  |  | $ | 14,136 |
Gains and losses realized from the sale of trading securities and net unrealized holding gains (losses) on trading securities are included in net gains (losses) on investment securities, (see Note 22). For fiscal 2009, 2010 and 2011, net unrealized holding gains and losses on trading securities were losses of ¥13,065 million, gains of ¥7,211 million and gains of ¥2,065 million ($25 million), respectively. During fiscal 2009 and 2010, the Company and its subsidiaries sold available-for-sale securities for aggregate proceeds of ¥242,702 million and ¥181,033 million, respectively, resulting in gross realized gains of ¥8,266 million and ¥7,547 million, respectively, and gross realized losses of ¥4,932 million and ¥640 million, respectively. During fiscal 2011, the Company and its subsidiaries sold available-for-sale securities for aggregate proceeds of ¥340,634 million ($4,095 million), resulting in gross realized gains of ¥5,579 million ($67 million) and gross realized losses of ¥712 million ($8 million). The cost of the securities sold was based on the average cost of each such security held at the time of the sale. During fiscal 2009, 2010 and 2011, the Company and its subsidiaries charged losses on securities of ¥18,574 million, ¥23,634 million and ¥21,749 million ($262 million), respectively, to the accompanying consolidated statements of income for declines in market value of securities where the decline was considered as other than temporary. Other securities consist mainly of non-marketable equity securities, preferred capital shares carried at cost and investment funds carried at an amount that reflects equity income and loss based on the investor’s share. The aggregate carrying amount of other securities accounted for under the cost method totaled ¥72,347 million and ¥67,366 million ($810 million) at March 31, 2010 and 2011. Investments with an aggregate cost of ¥62,208 million and ¥63,590 million ($765 million) were not evaluated for impairment because the Company and its subsidiaries did not identify any events or changes in circumstances that might have had significant adverse effect on the fair value of those investments and it was not practicable to estimate the fair value of the investments. The amortized cost basis amounts, gross unrealized holding gains, gross unrealized holding losses and fair values of available-for-sale securities and held-to-maturity securities in each major security type at March 31, 2010 and 2011 are as follows: March 31, 2010

Approximately 411 and 449 investment securities were in an unrealized loss position as of March 31, 2010 and 2011, respectively. The gross unrealized losses on these securities are attributable to a number of factors including changes in interest rates, credit spreads and market trends. For debt securities, in the case of the fair value being below the amortized cost, the Company and its subsidiaries consider that an other-than-temporary impairment has occurred if (1) the Company and its subsidiaries intend to sell the debt security; (2) it is more likely than not that the Company and its subsidiaries will be required to sell the debt security before recovery of its amortized cost basis, or (3) the Company and its subsidiaries do not expect to recover the entire amortized cost of the security (that is, a credit loss exists). In assessing whether a credit loss exists, the Company and its subsidiaries compare the present value of the expected cash flows to the security’s amortized cost basis at the balance sheet date. Debt securities with unrealized loss position mainly include specified bonds issued by special purpose entities in Japan and CMBS and RMBS. The unrealized loss associated with specified bonds is primarily due to changes in the market interest rate and risk premium because of deterioration in the domestic real estate market and the credit crunch in the capital and financial markets. Considering all available information to assess the collectibility of those investments (such as performance and value of the underlying real estate, and seniority of the bonds), the Company and its subsidiaries believe that the Company and its subsidiaries are able to recover the entire amortized cost basis of those investments. Because the Company and its subsidiaries do not intend to sell the investments and it is not more likely than not that the Company and its subsidiaries will be required to sell the investments before recovery of their amortized cost basis, the Company and its subsidiaries do not consider these investments to be other-than-temporarily impaired at March 31, 2011. The unrealized loss associated with CMBS and RMBS is primarily caused by changes in credit spreads and interest rates. In order to determine whether a credit loss exists, the Company and its subsidiaries estimate the present value of anticipated cash flows, discounted at the current yield to accrete the security. The cash flows are estimated based on a number of assumptions such as default rate and prepayment speed, as well as seniority of the security. Then, a credit loss is assessed by comparing the present value of the expected cash flows to the security’s amortized cost basis. Based on that assessment, the Company and its subsidiaries expect to recover the entire amortized cost basis. Because the Company and its subsidiaries do not intend to sell the investments and it is not more likely than not that the Company and its subsidiaries will be required to sell the investments before recovery of their amortized cost basis, the Company and its subsidiaries do not consider these investments to be other-than-temporarily impaired at March 31, 2011. For equity securities with unrealized losses, the Company and its subsidiaries consider various factors to determine whether the decline is other-than-temporary, including the length of time and the extent to which the fair value has been less than the carrying value and the issuer’s specific economic conditions as well as the ability and intent to hold these securities for a period of time sufficient to recover the securities’ carrying amounts. Based on our ongoing monitoring process, the Company and its subsidiaries do not consider these investments to be other-than-temporarily impaired at March 31, 2011. The total other-than-temporary impairment with an offset for the amount of the total other-than-temporary impairment recognized in other comprehensive income (loss) for fiscal 2009, 2010 and 2011 are as follows:
|  | Millions of yen |  |  | Millions of U.S. dollars |
|  | 2009 |  |  | 2010 |  |  | 2011 |  |  | 2011 |
Total other-than-temporary impairment losses |  | ¥ | 20,060 |  |  | ¥ | 26,057 |  |  | ¥ | 22,212 |  |  | $ | 267 |
Portion of loss recognized in other comprehensive income (before taxes) |  |  | (1,486 | ) |  |  | (2,423 | ) |  |  | (463 | ) |  |  | (5 | )
Net impairment losses recognized in earnings |  | ¥ | 18,574 |  |  | ¥ | 23,634 |  |  | ¥ | 21,749 |  |  | $ | 262 |
Other-than-temporary impairment losses related to debt securities are recognized mainly on certain specified bonds, which have experienced credit losses due to significant decline in the value of the underlying assets, as well as on certain mortgage-backed and other asset-backed securities, which have experienced credit losses due to a decrease in cash flows attributable to significant default and bankruptcies on the underlying loans. Because the Company and its subsidiaries do not intend to sell these securities and it is not more likely than not that the Company and its subsidiaries will be required to sell these securities before recovery of their amortized cost basis, the Company and its subsidiaries charged only the credit loss component of the total impairment to earnings with the remaining non-credit component recognized in other comprehensive income (loss). The credit loss assessment was made by comparing the securities’ amortized cost basis with the portion of the estimated fair value of the underlying assets available to repay the specified bonds, or with the present value of the expected cash flows from the mortgage-backed and other asset- backed securities, that were estimated based on a number of assumptions such as default rate and prepayment speed, as well as seniority of the security. Roll-forwards of the amount related to credit losses on other-than-temporarily impaired debt securities recognized in earnings for fiscal 2010 and 2011 are as follows:

Securities not due at a single maturity date, such as mortgage-backed securities, are included in the above table based on their final maturities. Certain borrowers may have the right to call or prepay obligations. This right may cause actual maturities to differ from the contractual maturities summarized above. Included in interest on loans and investment securities in the consolidated statements of income is interest income on investment securities of ¥23,758 million, ¥20,436 million and ¥17,690 million ($213 million) for fiscal 2009, 2010 and 2011, respectively. A certain foreign subsidiary acquired debt securities with evidence of deterioration of credit quality at the time of acquisition, and those debt securities were probably not able to recover all contractual amounts. In accordance with the provision of ASC 310-30 (Receivables—Loans and Debt Securities Acquired with Deteriorated Credit Quality), the subsidiary determined the expected future cash flows taking into account historical cash collections for debt securities with similar characteristics as well as expected prepayments and the amount and the timing of undiscounted expected principal, interest and other cash flows for each pool of debt securities. Accretable yield represents the excess of expected future cash flows over carrying value of the debt securities, which is recognized as interest income over the remaining life of the debt securities. For a debt security for which the fair value is less than the amortized cost basis, the subsidiary estimates the present value of cash flows expected to be collected from the security and compares it with the amortized cost basis of the security to determine whether a credit loss exists. If, based on current information and events, the subsidiary determines a credit loss exists for that security, an other-than-temporary impairment is considered to have occurred. The subsidiary writes down that security to fair value with the credit loss component of the impairment recognized in earnings and the noncredit component recorded in other comprehensive income (loss), unless the subsidiary intends to sell that security or more likely than not will be required to sell that security before recovery, in which case the entire impairment loss would be charged to earnings. As of March 31, 2010 and 2011, the carrying amount and the nominal value of debt securities acquired with evidence of deterioration of credit quality were ¥11,880 million and ¥7,612 million ($92 million), and ¥40,605 million and ¥18,090 million ($218 million), and the outstanding balance of accretable yield was ¥10,420 million and ¥6,202 million ($75 million) respectively.
