The use of foreign currency exchange contracts, futures contracts, and swap contracts involves elements of market risk and risks in excess of the amounts disclosed in the schedule of investments. The notional amounts and foreign currency exchange contracts presented above represent the Fund's total exposure in such contracts, whereas only the net unrealized appreciation (depreciation) and variation margin are reflected in the Fund's net assets.

1	A CDS contract is a risk-transfer instrument through which one party (purchaser of protection) transfers to another party (seller of protection) the financial risk of a credit event (as defined in the CDS agreement), as it relates to a particular reference security or basket of securities (such as an index). Periodic payments (receipts) on such contracts are accrued daily and recorded as unrealized losses (gains) on swap contracts. Upon payment (receipt), such amounts are recorded as realized losses (gains) on swap contracts. Upfront payments made or received in connection with CDS contracts are amortized over the expected life of the CDS contracts as unrealized losses (gains) on swap contracts. The change in value of CDS contracts is recorded daily as unrealized appreciation or depreciation. A realized gain or loss is recorded upon a credit event (as defined in the CDS agreement) or the maturity or termination of the CDS agreement.
2	Notional amount shown is stated in USD unless noted that the swap is denominated in another currency.
3	Unrealized appreciation (depreciation) does not include periodic interest payments (receipt) on swap contracts accrued daily in the amount of $(2,251,209).

⁴	Markit’s iTraxx Europe Subordinated Financials Index, or the ITRX EUR SUB FIN, is comprised of 25 Financial entities from the Markit iTraxx^® Europe Index referencing subordinated debt.
⁵	Markit’s North America Investment Grade Index, or the CDX.NA.IG

	Index, is composed of 125 liquid North American entities with investment grade credit ratings that trade in the CDS market.
⁶	Markit’s CMBX Index, or the CMBX.NA Index, is a synthetic tradable index referencing a basket of 25 commercial mortgage backed securities in North America. Credit-quality rating are measured on a scale that generally ranges from AAA (highest) to BB (lowest). US Agency and US Agency mortgage-backed securities appear under US Government.
⁷	An IRS agreement is an exchange of interest rates between counterparties. Periodic payments (receipt) on such contracts are accrued daily and recorded as unrealized appreciation (depreciation) on swap contracts. Upon periodic payment (receipt) or termination of the contract, such amounts are recorded as realized gains (losses) on swap contracts.
