Core Fixed Income Fund (Concluded)

As of December 31, 2020, the Core Fixed Income Fund is the seller (“providing protection”) on a total notional amount of $146.3 million. The notional amounts of the swaps are not recorded in the financial statements. The notional amounts 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 was to occur. Those credit default swaps (“CDS”) for which the Fund is providing protection at the balance sheet date are summarized as follows:

There may be other potential recoveries from recourse provisions where agreements cover multiple derivative arrangements but those amounts have not been included.

[1] If Management uses credit ratings to evaluate the credit risk of an underlying asset, it may use such ratings in its disclosure by replacing credit spreads by credit ratings.

* 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.

High Yield Bond Fund (Concluded)

[1] If Management uses credit ratings to evaluate the credit risk of an underlying asset, it may use such ratings in its disclosure by replacing credit spreads by credit ratings.

* 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.

[1] If Management uses credit ratings to evaluate the credit risk of an underlying asset, it may use such ratings in its disclosure by replacing credit spreads by credit ratings.

* 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.

[1] If Management uses credit ratings to evaluate the credit risk of an underlying asset, it may use such ratings in its disclosure by replacing credit spreads by credit ratings.

* 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.

There may be other potential recoveries from recourse provisions where agreements cover multiple derivative arrangements but those amounts have not been included.

[1] If Management uses credit ratings to evaluate the credit risk of an underlying asset, it may use such ratings in its disclosure by replacing credit spreads by credit ratings.

* 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.

Multi-Asset Capital Stability Fund (Concluded)

As of December 31, 2020, Multi-Asset Capital Stability Fund is the seller (“providing protection”) on a total notional amount of $33.9 million. The notional amounts of the swaps are not recorded in the financial statements. The notional amounts 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 was to occur. Those credit default swaps (“CDS”) for which the Fund is providing protection at the balance sheet date are summarized as follows:

WRITTEN CREDIT DERIVATIVE CONTRACTS	SINGLE NAME CREDIT DEFAULT SWAPS				CREDIT DEFAULT SWAP INDEX
REFERENCE ASSET	Corporate Debt		Sovereign Debt		Asset Backed Securities		Corporate Debt		Total
Fair value of written credit derivatives		-		-		-	$	1,554,986	$	1,554,986
Maximum potential amount of future payments		-		-		-		32,316,225		32,316,225
Recourse provisions with third parties to recover any amounts paid under the credit derivative (including any purchased credit protection)[1]		-		-		-		-		-
Collateral held by the Fund can obtain upon occurrence of triggering event		-		-		-		-		-

[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.

MAXIMUM POTENTIAL AMOUNT OF FUTURE PAYMENTS BY CONTRACT TERM

[1] If Management uses credit ratings to evaluate the credit risk of an underlying asset, it may use such ratings in its disclosure by replacing credit spreads by credit ratings.

* 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.
