| | (1) | Residential mortgage-backed securities (RMBS) originated by U.S. agencies. |
| | (2) | Commercial mortgage-backed securities (CMBS). |
| | (3) | Asset-backed securities (ABS) include debt tranched securities collateralized primarily by auto loans, student loans, credit cards, and other asset types. This asset class also includes collateralized loan obligations (CLOs) and collateralized debt obligations (CDOs). |
| | (4) | Municipals include bonds issued by states, municipalities and political subdivisions. |
| | (5) | Represents the non-credit component of the other-than-temporary impairment (OTTI) losses, adjusted for subsequent sales of securities. It does not include the change in fair value subsequent to the impairment measurement date. |
In the normal course of investing activities, we actively manage allocations to non-controlling tranches of structured securities (variable interests) issued by VIEs. These structured securities include RMBS, CMBS and ABS and are included in the above table. Additionally, within our other investments portfolio, we also invest in limited partnerships (hedge funds) and CLO equity tranched securities (CLO Equities), which are all variable interests issued by VIEs (see Note 3(b)). For these variable interests, we do not have the power to direct the activities that are most significant to the economic performance of the VIEs and accordingly we are not the primary beneficiary for any of these VIEs. Our maximum exposure to loss on these interests is limited to the amount of our investment. We have not provided financial or other support with respect to these structured securities other than our original investment.
Contractual Maturities
The contractual maturities of fixed maturities are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. | | | | | | | | | | | | | | | | Amortized Cost | | Fair Value | | % of Total Fair Value | | | | | | | | | | | At June 30, 2013 | | | | | | | | Maturity | | | | | | | | Due in one year or less | $ | 642,706 |

Fixed Maturities
At June 30, 2013, 1,512 fixed maturities (2012: 478) were in an unrealized loss position of $194 million (2012: $18 million), of which$11 million (2012: $3 million) was related to securities below investment grade or not rated.
At June 30, 2013, 95 (2012: 146) securities have been in continuous unrealized loss position for 12 months or greater and have a fair value of $130 million (2012: $268 million). Following our credit impairment review, we concluded that these securities as well as the remaining securities in an unrealized loss position in the above table were temporarily impaired at June 30, 2013, and are expected to recover in value as the securities approach maturity. Further, at June 30, 2013, we did not intend to sell these securities in an unrealized loss position and it is more likely than not that we will not be required to sell these securities before the anticipated recovery of their amortized costs.
Equity Securities
At June 30, 2013, 101 securities (2012: 106) were in an unrealized loss position of $8 million (2012: $7 million).
At June 30, 2013, 19 (2012: 17) securities have been in a continuous unrealized loss position for 12 months or greater and have a fair value of $9 million (2012: $12 million). Based on our impairment review process and our ability and intent to hold these securities for a reasonable period of time sufficient for a full recovery, we concluded that all remaining equities in an unrealized loss position were temporarily impaired at June 30, 2013. b) Other Investments

n/a - not applicable
The investment strategies for the above funds are as follows:
| | • | Long/short equity funds: Seek to achieve attractive returns by executing an equity trading strategy involving both long and short investments in publicly-traded equities. |
| | • | Multi-strategy funds: Seek to achieve above-market returns by pursuing multiple investment strategies to diversify risks and reduce volatility. This category includes funds of hedge funds which invest in a large pool of hedge funds across a diversified range of hedge fund strategies. |
| | • | Event-driven funds: Seek to achieve attractive returns by exploiting situations where announced or anticipated events create opportunities. |
| | • | Leveraged bank loan funds: Seek to achieve attractive returns by investing primarily in bank loan collateral that has limited interest rate risk exposure. |
| | • | Direct lending funds: Seek to achieve attractive risk-adjusted returns, including significant current income generation, by investing in funds which provide financing directly to borrowers. |
Two common redemption restrictions which may impact our ability to redeem our hedge funds are gates and lockups. A gate is a suspension of redemptions which may be implemented by the general partner or investment manager of the fund in order to defer, in whole or in part, the redemption request in the event the aggregate amount of redemption requests exceeds a predetermined percentage of the fund's net assets which may otherwise hinder the general partner or investment manager's ability to liquidate holdings in an orderly fashion in order to generate the cash necessary to fund extraordinarily large redemption payouts. A lockup period is the initial amount of time an investor is contractually required to hold the security before having the ability to redeem. During 2013 and 2012, neither of these restrictions impacted our redemption requests. At June 30, 2013, $95 million (2012: $38 million), representing 10% (2012: 5%) of our total hedge funds, relate to holdings where we are still within the lockup period. The expiries of these lockup periods range from April, 2014 to April, 2016. No other category contains investments currently subject to lockup.
At June 30, 2013, $14 million (2012: $29 million) of our hedge funds was invested in funds that are not accepting redemption requests. Of this amount, substantially all relates to a leveraged bank loan fund in a period of planned principal distributions which has a target completion date in late 2013 and, based on current market conditions and payments made to date, management expects this target date to be met. The remainder primarily relates to funds that entered liquidation or had their assets side pocketed as a result of the global financial crisis which began in late 2008. For these funds, management is currently unable to estimate when those funds will be distributed.
At June 30, 2013, we have $106 million (2012: $40 million) of unfunded commitments within our other investments portfolio relating to our future investments in direct lending funds. Once the full amount of committed capital has been called by the General Partner of each of these funds, the assets will not be fully returned until the completion of the fund's investment term. These funds have investment terms ranging from 5-10 years and the General Partners of certain funds have the option to extend the term by up to three years.

e) Reverse Repurchase Agreements
At June 30, 2013, we held $211 million (2012: $39 million) of reverse repurchase agreements. These loans are fully collateralized, are generally outstanding for a short period of time and are presented on a gross basis as part of cash and cash equivalents on our consolidated balance sheet. The required collateral for these loans is either cash or U.S. Treasuries at a minimum rate of 102% of the loan principal. Upon maturity, we receive principal and interest income. |
