Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers. The persons or companies from whom the investment company purchased or to whom it sold portfolio instruments on a principal basis may be persons or entities not registered under the Exchange Act as securities dealers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers. The persons or companies from whom the investment company purchased or to whom it sold portfolio instruments on a principal basis may be persons or entities not registered under the Exchange Act as securities dealers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers. The persons or companies from whom the investment company purchased or to whom it sold portfolio instruments on a principal basis may be persons or entities not registered under the Exchange Act as securities dealers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers. The persons or companies from whom the investment company purchased or to whom it sold portfolio instruments on a principal basis may be persons or entities not registered under the Exchange Act as securities dealers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers. The persons or companies from whom the investment company purchased or to whom it sold portfolio instruments on a principal basis may be persons or entities not registered under the Exchange Act as securities dealers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers. The persons or companies from whom the investment company purchased or to whom it sold portfolio instruments on a principal basis may be persons or entities not registered under the Exchange Act as securities dealers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly. The agents considered in Item C.16 may be persons or companies not registered under the Exchange Act as securities brokers.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly.

Item C.16. Brokers.

Instructions to Item C.16 and Item C.17.
To help Registrants distinguish between agency and principal transactions, and to promote consistent reporting of the information required by these items, the following criteria should be used:
1. If a security is purchased or sold in a transaction for which the confirmation specifies the amount of the commission to be paid by the Registrant, the transaction should be considered an agency transaction and included in determining the answers to Item C.16.
2. If a security is purchased or sold in a transaction for which the confirmation specifies only the net amount to be paid or received by the Registrant and such net amount is equal to the market value of the security at the time of the transaction, the transaction should be considered a principal transaction and included in determining the amounts in Item C.17.
3. If a security is purchased by the Registrant in an underwritten offering, the acquisition should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the underwriters are receiving from the issuer.
4. If a security is sold by the Registrant in a tender offer, the sale should be considered a principal transaction and included in answering Item C.17 even though the Registrant has knowledge of the amount the offeror is paying to soliciting brokers or dealers.
5. If a security is purchased directly from the issuer (such as a bank CD), the purchase should be considered a principal transaction and included in answering Item C.17.
6. The value of called or maturing securities should not be counted in either agency or principal transactions and should not be included in determining the amounts shown in Item C.16 and Item C.17. This means that the acquisition of a security may be included, but it is possible that its disposition may not be included. Disposition of a repurchase agreement at its expiration date should not be included.
7. The purchase or sales of securities in transactions not described in paragraphs (1) through (6) above should be evaluated by the Fund based upon the guidelines established in those paragraphs and classified accordingly.
