Common use of Credit Default Swap Agreements Clause in Contracts

Credit Default Swap Agreements. The Fund may enter into credit default swap agreements for hedging purposes or to seek to increase its return. The credit default swap agreement may have as reference obligations one or more securities that are not currently held by the Fund. The protection "buyer" in a credit default contract may be obligated to pay the protection "seller" an upfront or a periodic stream of payments over the term of the contract provided that no credit event on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the "par value" (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is cash settled. The Fund may be either the buyer or seller in the transaction. If the Fund is a buyer and no credit event occurs, the Fund may recover nothing if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap, which typically is between six months and three years, provided that there is no credit event. If a credit event occurs, generally the seller must pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap. Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risks. The Fund will enter into credit default swap agreements only with counterparties the Investment Adviser believes to be creditworthy at the time they enter into such transactions. A buyer generally also will lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. The Fund's obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund). The Fund will at all times segregate or designate on its books and records in connection with each such transaction liquid assets or cash with a value at least equal to the Fund's exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty) on a marked-to-market basis (as calculated pursuant to requirements of the SEC). If the Fund is a seller of protection in a credit default swap transaction, it will segregate or designate on its books and records in connection with such transaction liquid assets or cash with a value at least equal to the full notional amount of the contract. Such segregation or designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund's portfolio. Such segregation or designation will not limit the Fund's exposure to loss.

Credit Default Swap Agreements. The Fund may enter into credit default swap agreements for hedging purposes or to seek to increase its return. The credit default swap agreement may have as reference obligations one or more securities that are not currently held by the Fund. The protection "buyer" in a credit default contract may be obligated to pay the protection "seller" an upfront or a periodic stream of payments over the term of the contract contract, provided that no credit event on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the "par value" (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is cash settled. The Fund may be either the buyer or seller in the transaction. If the Fund is a buyer and no credit event occurs, the Fund may recover nothing if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap, which typically is between six (6) months and three years, provided that there is no credit event. If a credit event occurs, generally the seller must pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap. Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risks.

Such segregation or designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund's portfolio. Such segregation or designation will not limit the Fund's exposure to loss. VRDOs are tax-exempt obligations that contain a floating or variable interest rate adjustment formula and right of demand on the part of the holder thereof to receive payment of the unpaid principal balance plus accrued interest upon a short notice period not to exceed seven days. There is, however, the possibility that because of default or insolvency the demand feature of VRDOs and Participating VRDOs may not be honored. The interest rates are adjustable at intervals (ranging from daily to up to one year) to some prevailing market rate for similar investments, such adjustment formula being calculated to maintain the market value of the VRDOs, at approximately the par value of the VRDOs on the adjustment date. The adjustments typically are based upon the SIFMA Municipal Swap Index or some other appropriate interest rate adjustment index. The Fund may invest in all types of tax exempt instruments currently outstanding or to be issued in the future which satisfy its short term maturity and quality standards. Participating VRDOs provide the Fund with a specified undivided interest (up to 100%) of the underlying obligation and the right to demand payment of the unpaid principal balance plus accrued interest on the Participating VRDOs from the financial institution upon a specified number of days' notice, not to exceed seven days. In addition, the Participating VRDO is backed by an irrevocable letter of credit or guaranty of the financial institution. The Fund would have an undivided interest in the underlying obligation and thus participate on the same basis as the financial institution in such obligation except that the financial institution typically retains fees out of the interest paid on the obligation for servicing the obligation, providing the letter of credit and issuing the repurchase commitment. It is contemplated that the Fund will not invest more than 20% of its assets in Participating VRDOs. VRDOs that contain an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest on a notice period exceeding seven days may be deemed to be illiquid securities. The Directors may adopt guidelines and delegate to the Investment Adviser the daily function of determining and monitoring liquidity of such VRDOs. The Temporary Investments, VRDOs and Participating VRDOs in which the Fund may invest will be in the following rating categories at the time of purchase: MIG-1/VMIG-1 through MIG-3/VMIG-3 for notes and VRDOs and Prime-1 through Prime-3 for commercial paper (as determined by Moody's), SP-1 through SP-2 for notes and A-1 through A-3 for VRDOs and commercial paper (as determined by S&P), or F-1 through F-3 for notes, VRDOs and commercial paper (as determined by Fitch). Temporary Investments, if not rated, must be of comparable quality in the opinion of the Investment Adviser. In addition, the Fund reserves the right to invest temporarily a greater portion of its assets in Temporary Investments for defensive purposes, when, in the judgment of the Investment Adviser, market conditions warrant.

Credit Default Swap Agreements. The Fund may enter into credit default swap agreements for hedging purposes or to seek to increase enhance its returnreturns.

However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value that may have significantly decreasedlittle or no value. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap, which typically is between six months and three years, provided that there is no credit event. If a credit event occurs, generally the seller must pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value that may have significantly decreasedlittle or no value. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap. Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risksCall Options. The Fund will enter into credit default swap agreements only with counterparties may purchase call options on any of the Investment Adviser believes types of securities in which it may invest. A purchased call option gives the Fund the right to be creditworthy buy, and obligates the seller to sell, the underlying security at the exercise price at any time they enter into such transactionsduring the option period. A buyer generally The Fund may also will lose its investment purchase and recover nothing should no credit event occur and sell call options on indices. Index options are similar to options on securities except that, rather than taking or making delivery of securities underlying the swap option at a specified price upon exercise, an index option gives the holder the right to receive cash upon exercise of the option if the level of the index upon which the option is held based is greater than the exercise price of the option. Put Options. The Fund is authorized to its termination date. If purchase put options to seek to hedge against a credit event were to occur, decline in the value of its securities or to seek to enhance its return. By buying a put option, the Fund acquires a right to sell the underlying security at the exercise price, thus limiting the Fund’s risk of loss through a decline in the market value of the security until the put option expires. The amount of any deliverable obligation received appreciation in the value of the underlying security will be partially offset by the selleramount of the premium paid for the put option and any related transaction costs. Prior to its expiration, coupled with the upfront or periodic payments previously received, a put option may be sold in a closing sale transaction and profit or loss from the sale will depend on whether the amount received is more or less than the full notional value it pays premium paid for the put option plus the related transaction costs. A closing sale transaction cancels out the Fund’s position as the purchaser of an option by means of an offsetting sale of an identical option prior to the buyer, resulting in a loss expiration of value to the seller. The Fund's obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund)option it has purchased. The Fund also may purchase uncovered put options. Restrictions on the Use of Futures Transactions. Under regulations of the CFTC, the futures trading activity described herein will at all times segregate or designate on its books and records not result in connection with each such transaction liquid assets or cash with a value at least equal to the Fund's exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty) on being deemed a marked-to-market basis (“commodity pool,” as calculated pursuant to requirements of the SEC). If the Fund is a seller of protection in a credit default swap transactiondefined under such regulations, it will segregate or designate on its books and records in connection with such transaction liquid assets or cash with a value at least equal to the full notional amount of the contract. Such segregation or designation will ensure provided that the Fund has assets available adheres to satisfy its obligations with respect certain restrictions. In particular, the Fund may purchase and sell futures contracts and options thereon (i) for bona fide hedging purposes and (ii) for non-hedging purposes, if the aggregate initial margin and premiums required to establish positions in such contracts and options does not exceed 5% of the transaction and will avoid any potential leveraging liquidation value of the Fund's ’s portfolio, after taking into account unrealized profits and unrealized losses on any such contracts and options. Such segregation Margin deposits may consist of cash or designation will not limit securities acceptable to the Fund's exposure to lossbroker and the relevant contract market.

The Fund may be either the buyer or seller in the transaction. If the Fund is a buyer and no credit event occurs, the Fund may recover nothing if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased.

The Fund's obligations under A seller of a credit default swap agreement will or similar instrument is exposed to many of the same risks of leverage since, if a credit event occurs, the seller may be accrued daily (offset against required to pay the buyer the full notional value of the contract net of any amounts owing to the Fund). The Fund will at all times segregate or designate on its books and records in connection with each such transaction liquid assets or cash with a value at least equal to the Fund's exposure (any accrued but unpaid net amounts owed by the Fund buyer related to any counterparty) on a marked-to-market basis (as calculated pursuant to requirements its delivery of the SEC). If the Fund is a seller of protection in a credit default swap transaction, it will segregate or designate on its books and records in connection with such transaction liquid assets or cash with a value at least equal to the full notional amount of the contract. Such segregation or designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund's portfolio.

Such segregation or designation will not limit the Fund's ’s exposure to loss. Futures Contracts and Options on Futures Contracts. The Fund may also enter into contracts for the purchase or sale for future delivery (“futures contracts”) of debt securities, aggregates of debt securities or indices or prices thereof, other financial indices and U.S. government debt securities or options on the above. The Fund will ordinarily engage in such transactions only for bona fide hedging, risk management (including duration management) and other portfolio management purposes. However, the Fund is also permitted to enter into such transactions for non-hedging purposes to enhance income or gain, in accordance with the rules and regulations of the Commodity Futures Trading Commission (the “CFTC”). The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a “commodity pool” or a vehicle for trading such instruments. Accordingly, the Investment Adviser has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) pursuant to Rule 4.5 under the CEA. The Investment Adviser is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Fund. When the Fund purchases a futures contract, or writes a put option or purchases a call option thereon, an amount of cash, cash equivalents (e.g. high grade commercial paper and daily tender adjustable notes) or liquid securities will be segregated or designated on its books and records, so that the amount so segregated or earmarked, plus the amount of initial and variation margin held in the account of its broker, equals the market value of the futures contracts, thereby ensuring that the use of such futures contract is unleveraged. Calls on Securities Indices and Futures Contracts. The Fund may sell or purchase call options (“calls”) on municipal bonds and indices based upon the prices of future contracts and debt securities that are traded on U.S. and foreign securities exchanges and in the over-the-counter markets. A call gives the purchaser of the option the right to buy, and obligates the seller to sell, the underlying security, futures contract or index at the exercise price at any time or at a specified time during the option period. All such calls sold by the Fund must be “covered” as long as the call is outstanding (i.e., the Fund must own the securities or futures contract subject to the call or other securities acceptable for applicable escrow requirements). A call sold by the Fund exposes the Fund during the term of the option to possible loss of opportunity to realize appreciation in the market price of the underlying security, index or futures contract and may require the Fund to hold a security of futures contract which it might otherwise have sold. The purchase of a call gives the Fund the right to buy a security, futures contract or index at a fixed price. Calls on futures on municipal bonds must also be covered by deliverable securities on the futures contract or by liquid high grade debt securities segregated or designated on the Fund’s books and records to satisfy the Fund’s obligations pursuant to such instruments. Puts on Securities, Indices and Futures Contracts. The Fund may purchase put options (“puts”) that relate to municipal bonds (whether or not it holds such securities in its portfolio), indices or futures contracts. The Fund may also sell puts on municipal bonds, indices or futures contracts on such securities if the Fund’s contingent obligations on such puts are secured by segregated assets consisting of cash or liquid high grade debt securities having a value not less than the exercise price. The Fund’s investment policies provide that it will not sell puts if, as a result, more than 50% of the Fund’s total assets would be required to cover its potential obligations under its hedging and other investment transactions. In selling puts, there is a risk that the Fund may be required to buy the underlying security at a price higher than the current market price. Municipal Market Data Rate Locks. The Fund may purchase and sell Municipal Market Data Rate Locks (“MMD Rate Locks”). An MMD Rate Lock permits the Fund to lock in a specified municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio as a duration management technique or to protect against any increase in the price of securities to be purchased at a later date. The Fund will ordinarily use these transactions as a hedge or for duration or risk management although it is permitted to enter into them to enhance income or gain. An MMD Rate Lock is a contract between the Fund and an MMD Rate Lock provider pursuant to which the parties agree to make payments to each other on a notional amount, contingent upon whether the Municipal Market Data AAA General Obligation Scale is above or below a specified level on the expiration date of the contract. For example, if the Fund buys an MMD Rate Lock and the Municipal Market Data AAA General Obligation Scale is below the specified level on the expiration date, the counterparty to the contract will make a payment to the Fund equal to the specified level minus the actual level, multiplied by the notional amount of the contract. If the Municipal Market Data AAA General Obligation Scale is above the specified level on the expiration date, the Fund will make a payment to the counterparty equal to the actual level minus the specified level multiplied by the notional amount of the contract. In entering into MMD Rate Locks, there is a risk that municipal yields will move in the direction opposite of the direction anticipated by the Fund, which would cause the Fund to make payments to its counterparty in the transaction that could adversely affect the Fund’s performance. The Fund has no obligation to enter into interest rate swap transactions such as Municipal Market Data AAA Cash Curve swaps (“MMD Swaps”) and may elect not to do so. The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each interest rate swap will be accrued on a daily basis, and the Fund will segregate or designate on its books and records liquid securities having an aggregate net asset value at least equal to the accrued excess. The Fund’s investment policies provide that it will not enter into MMD Rate Locks if, as a result, more than 50% of its total assets would be required to cover its potential obligations under its hedging and other investment transactions.

Credit Default Swap Agreements. The Fund may enter into credit default swap agreements for hedging purposes or to seek to increase its return. The credit default swap agreement may have as reference obligations one or more securities that are not currently held by the Fund. The protection "“buyer" ” in a credit default contract may be obligated to pay the protection "“seller" ” an upfront or a periodic stream of payments over the term of the contract contract, provided that no credit event on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the "“par value" ” (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amountamount (the difference between the market value of the reference obligation and its par value), if the swap is cash settled. The Fund may be either the buyer or seller in the transaction. If the Fund is a buyer and no credit event occurs, the Fund may recover nothing if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap, which typically is between six (6) months and three years, provided that there is no credit event. If a credit event occurs, generally the seller must pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap. Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risks. The Fund will enter into credit default swap agreements only with counterparties the Investment Adviser Advisor believes to be creditworthy at the time they enter into such transactions. A buyer generally also will lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. The Fund's ’s obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund). The Fund will at all times segregate or designate on its books and records in connection with each such transaction liquid assets or cash with a value at least equal to the Fund's ’s exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty) on a marked-to-market basis (as calculated pursuant to requirements of the SEC). If the Fund is a seller of protection in a credit default swap transaction, it will segregate or designate on its books and records in connection with such transaction liquid assets or cash with a value at least equal to the full notional amount of the contract. Such segregation or designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund's ’s portfolio. Such segregation or designation will not limit the Fund's ’s exposure to loss. VRDOs are tax-exempt obligations that contain a floating or variable interest rate adjustment formula and right of demand on the part of the holder thereof to receive payment of the unpaid principal balance plus accrued interest upon a short notice period not to exceed seven (7) days. There is, however, the possibility that because of default or insolvency the demand feature of VRDOs and Participating VRDOs may not be honored. The interest rates are adjustable at intervals (ranging from daily to up to one year) to some prevailing market rate for similar investments, such adjustment formula being calculated to maintain the market value of the VRDOs, at approximately the par value of the VRDOs on the adjustment date. The adjustments typically are based upon the SIFMA Municipal Swap Index or some other appropriate interest rate adjustment index. The Fund may invest in all types of tax-exempt instruments currently outstanding or to be issued in the future which satisfy its short-term maturity and quality standards. Participating VRDOs provide the Fund with a specified undivided interest (up to 100%) of the underlying obligation and the right to demand payment of the unpaid principal balance plus accrued interest on the Participating VRDOs from the financial institution upon a specified number of days’ notice, not to exceed seven (7) days. In addition, the Participating VRDO is backed by an irrevocable letter of credit or guaranty of the financial institution. The Fund would have an undivided interest in the underlying obligation and thus participate on the same basis as the financial institution in such obligation except that the financial institution typically retains fees out of the interest paid on the obligation for servicing the obligation, providing the letter of credit and issuing the repurchase commitment. The Fund has been advised by its counsel that the Fund should be entitled to treat the income received on Participating VRDOs as interest from tax-exempt obligations as long as the Fund does not invest more than 20% of its total assets in such investments and certain other conditions are met. It is contemplated that the Fund will not invest more than 20% of its assets in Participating VRDOs. The Temporary Investments, VRDOs and Participating VRDOs in which the Fund may invest will be in the following rating categories at the time of purchase: MIG-1/VMIG-1 through MIG-3/VMIG-3 for notes and VRDOs and Prime-1 through Prime-3 for commercial paper (as determined by Moody’s), SP-1 through SP-2 for notes and A-1 through A-3 for VRDOs and commercial paper (as determined by S&P), or F1 through F3 for notes, VRDOs and commercial paper (as determined by Fitch). Temporary Investments, if not rated, must be of comparable quality in the opinion of the Advisor. In addition, the Fund reserves the right to invest temporarily a greater portion of its assets in Temporary Investments for defensive purposes, when, in the judgment of the Advisor, market conditions warrant.

If a credit event occurs, generally the seller must pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap. Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risks. The Fund will enter into credit default swap agreements only with counterparties the Investment Adviser believes to be creditworthy at the time they enter into such transactions. A buyer generally also will lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. The Fund's ’s obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund). The Fund will at all times segregate or designate on its books and records in connection with each such transaction liquid assets or cash with a value at least equal to the Fund's ’s exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty) on a marked-to-market basis (as calculated pursuant to requirements of the SEC). If the Fund is a seller of protection in a credit default swap transaction, it will segregate or designate on its books and records in connection with such transaction liquid assets or cash with a value at least equal to the full notional amount of the contract. Such segregation or designation will ensure that the Fund has assets available to satisfy its obligations with respect to the transaction and will avoid any potential leveraging of the Fund's ’s portfolio. Such segregation or designation will not limit the Fund's ’s exposure to loss. VRDOs and Participating VRDOs VRDOs are tax-exempt obligations that contain a floating or variable interest rate adjustment formula and right of demand on the part of the holder thereof to receive payment of the unpaid principal balance plus accrued interest upon a short notice period not to exceed seven days. There is, however, the possibility that because of default or insolvency the demand feature of VRDOs and Participating VRDOs may not be honored. The interest rates are adjustable at intervals (ranging from daily to up to one year) to some prevailing market rate for similar investments, such adjustment formula being calculated to maintain the market value of the VRDOs, at approximately the par value of the VRDOs on the adjustment date. The adjustments typically are based upon the SIFMA Municipal Swap Index or some other appropriate interest rate adjustment index. The Fund may invest in all types of tax exempt instruments currently outstanding or to be issued in the future which satisfy its short term maturity and quality standards. Participating VRDOs provide the Fund with a specified undivided interest (up to 100%) of the underlying obligation and the right to demand payment of the unpaid principal balance plus accrued interest on the Participating VRDOs from the financial institution upon a specified number of days’ notice, not to exceed seven days. In addition, the Participating VRDO is backed by an irrevocable letter of credit or guaranty of the financial institution. The Fund would have an undivided interest in the underlying obligation and thus participate on the same basis as the financial institution in such obligation except that the financial institution typically retains fees out of the interest paid on the obligation for servicing the obligation, providing the letter of credit and issuing the repurchase commitment. It is contemplated that the Fund will not invest more than 20% of its assets in Participating VRDOs. VRDOs that contain an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest on a notice period exceeding seven days may be deemed to be illiquid securities. The Directors may adopt guidelines and delegate to the Investment Adviser the daily function of determining and monitoring liquidity of such VRDOs. The Temporary Investments, VRDOs and Participating VRDOs in which the Fund may invest will be in the following rating categories at the time of purchase: MIG 1/VMIG 1 through MIG 3/VMIG 3 for notes and VRDOs and Prime-1 through Prime-3 for commercial paper (as determined by Xxxxx’x), SP-1 through SP-2 for notes and A-1 through A-3 for VRDOs and commercial paper (as determined by S&P), or F1 through F3 for notes, VRDOs and commercial paper (as determined by Fitch). Temporary Investments, if not rated, must be of comparable quality in the opinion of the Investment Adviser. In addition, the Fund reserves the right to invest temporarily a greater portion of its assets in Temporary Investments for defensive purposes, when, in the judgment of the Investment Adviser, market conditions warrant.
