Credit Default Swaps

On September 12, 2008, the FASB issued FASB Staff Position (“FSP”) No. FAS 133-1 and FASB Interpretation Number (“FIN”) 45-4 (“FSP 133-1”), Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No. 45; and Clarification of the Effective Date of FASB Statement No. 161. The FSP is intended to improve disclosures about credit derivatives by requiring more information about the potential adverse effects of changes in credit risk on the financial position, financial performance, and cash flows of the sellers of credit derivatives. It amends FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities, to require disclosures by sellers of credit derivatives, including credit derivatives embedded in hybrid instruments. The FSP also amends FIN 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness to Others, to require an additional disclosure about the current status of the payment/performance risk of a guarantee. FSP 133-1 and FIN 45-4 is effective for reporting periods (annual or interim) ending after November 15, 2008 and was adopted by the Fund effective November 30, 2008.

The Fund enters into credit default swaps to simulate long and short bond positions that are either unavailable or considered to be less attractively priced in the bond market. The Fund uses these swaps to reduce risk where the Fund has exposure to the issuer, or to take an active long or short position with respect to the likelihood of an event of default. The reference obligation of the swap can be a single issuer, a “basket” of issuers, or an index. The underlying referenced assets are corporate debt, sovereign debt and asset backed securities.

The buyer of a credit default swap is generally obligated to pay the seller a periodic stream of payments over the term of the contract in return for a contingent payment upon the occurrence of a credit event with respect to an underlying reference obligation. Generally, a credit event for corporate or sovereign reference obligations means bankruptcy, failure to pay, obligation acceleration, repudiation/moratorium or restructuring. For credit default swaps on asset-backed securities, a credit event may be triggered by events such as failure to pay principal, maturity extension, rating downgrade or write-down. If a credit event occurs, the seller typically must pay the contingent payment to the buyer, which is typically the par value (full notional value) of the reference obligation, though the actual payment may be mitigated by terms of the International Swaps and Derivative Agreement (“ISDA”), allowing for netting arrangements and collateral. After a credit event occurs, this amount may be reduced by anticipated recovery rates, segregated collateral and netting arrangements that may incorporate multiple transactions with a given counterparty.

The contingent payment may be a cash settlement or a physical delivery of the reference obligation in return for payment of the face amount of the obligation. If the Fund is a buyer and no credit event occurs, the Fund may lose its investment and recover nothing. However, if a credit event occurs, the buyer typically receives full notional value for a reference obligation that may have little or no value. As a seller, the Buyer receives a fixed rate of income throughout the term of the contract, which typically is between one month and five years, provided that no credit event occurs. If a credit event occurs, the seller may pay the buyer the full notional value of the reference obligation. As of February 28, 2010, the Fund is the buyer (“receiving protection”) on a total notional amount of $86.8 million)1 and is the seller (“providing protection”) on a total notional amount of $79.3 million. The notional amounts of the swaps are not recorded in the financial statements; however the notional amount does approximate the maximum potential amount of future payments that the Fund could be required to make if the Fund were the seller of protection and a credit event were to occur. Those credit default swaps for which the Fund is providing protection at balance sheet date are summarized as follows:

(1)   Potential recoveries would include purchased credit derivatives to the extent they offset written credit derivatives which have an identical underlying, or a netting arrangement or credit support annex with the counterparty. There may be other potential recoveries from recourse provisions where agreements cover multiple derivative arrangements but those amounts have not been included.

*   The credit spread on the underlying asset is generally indicative of the current status of the underlying risk of the Fund having to perform. The spread also reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into a contract. Higher credit spreads with a shorter contract term is indicative of a higher likelihood of performance by the Fund.

Credit Default Swaps

On September 12, 2008, the FASB issued FASB Staff Position (“FSP”) No. FAS 133-1 and FASB Interpretation Number (“FIN”) 45-4 (“FSP 133-1”), Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of FASB Statement No.133 and FASB Interpretation No.45; and Clarification of the Effective Date of FASB Statement No. 161. The FSP is intended to improve disclosures about credit derivatives by requiring more information about the potential adverse effects of changes in credit risk on the financial position, financial performance, and cash flows of the sellers of credit derivatives. It amends FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities, to require disclosures by sellers of credit derivatives, including credit derivatives embedded in hybrid instruments. The FSP also amends FIN 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness to Others, to require an additional disclosure about the current status of the payment/performance risk of a guarantee. FSP 133-1 and FIN 45-4 is effective for reporting periods (annual or interim) ending after November 15, 2008 and was adopted by the Trust effective November 30, 2008.

The Fund enters into credit default swaps to simulate long and short bond positions that are either unavailable or considered to be less attractively priced in the bond market. The Fund uses these swaps to reduce risk where the Fund has exposure to the issuer, or to take an active long or short position with respect to the likelihood of an event of default. The reference obligation of the swap can be a single issuer, a “basket” of issuers, or an index. The underlying referenced assets are corporate debt, sovereign debt and asset backed securities.

The buyer of a credit default swap is generally obligated to pay the seller a periodic stream of payments over the term of the contract in return for a contingent payment upon the occurrence of a credit event with respect to an underlying reference obligation. Generally, a credit event for corporate or sovereign reference obligations means bankruptcy, failure to pay, obligation acceleration, repudiation/moratorium or restructuring. For credit default swaps on asset-backed securities, a credit event may be triggered by events such as failure to pay principal, maturity extension, rating downgrade or write-down. If a credit event occurs, the seller typically must pay the contingent payment to the buyer, which is typically the par value (full notional value) of the reference obligation, though the actual payment may be mitigated by terms of the International Swaps and Derivative Agreement (“ISDA”), allowing for netting arrangements and collateral. After a credit event occurs, this amount may be reduced by anticipated recovery rates, segregated collateral and netting arrangements that may incorporate multiple transactions with a given counterparty.

The contingent payment may be a cash settlement or a physical delivery of the reference obligation in return for payment of the face amount of the obligation. If the Fund is a buyer and no credit event occurs, the Fund may lose its investment and recover nothing. However, if a credit event occurs, the buyer typically receives full notional value for a reference obligation that may have little or no value. As a seller, the Buyer receives a fixed rate of income throughout the term of the contract, which typically is between one month and five years, provided that no credit event occurs. If a credit event occurs, the seller may pay the buyer the full notional value of the reference obligation. As of February 28, 2010, the Fund is the buyer (“receiving protection”) on a total notional amount of $0.0 million)1 and is the seller (“providing protection”) on a total notional amount of $1.2 million. The notional amounts of the swaps are not recorded in the financial statements; however the notional amount does approximate the maximum potential amount of future payments that the Fund could be required to make if the Fund were the seller of protection and a credit event were to occur. Those credit default swaps for which the Fund is providing protection at balance sheet date are summarized as follows:

(1)   For purposes of quantifying this disclosure, potential recoveries would include purchased credit derivatives to the extent they offset written credit derivatives which have an identical underlying, or a netting arrangement or credit support annex with the counterparty. There may be other potential recoveries from recourse provisions where agreements cover multiple derivative arrangements but those amounts have not been included.

The credit spread on the underlying asset is generally indicative of the current status of the underlying risk of the Fund having to perform. The spread also reflects the cost of buying/selling protection and may include up front payment required to be made to enter into a contract. Higher credit spreads with a shorter contract term is indicative of a higher likelihood of performance by the Fund.
