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.

If the Registrant has not adopted such a code of ethics, explain why it has not done so.
(2) For purposes of this instruction, the term "code of ethics" means written standards that are reasonably designed to deter wrongdoing and to promote: (i) honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships; (ii) full, fair, accurate, timely, and understandable disclosure in reports and documents that a Registrant files with, or submits to, the Commission and in other public communications made by the Registrant; (iii) compliance with applicable governmental laws, rules, and regulations; (iv) the prompt internal reporting of violations of the code to an appropriate person or persons identified in the code; and (v) accountability for adherence to the code.

(3) The Registrant must briefly describe the nature of any amendment, during the period covered by the report, to a provision of its code of ethics that applies to the Registrant's principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, regardless of whether these individuals are employed by the Registrant or a third party, and that relates to any element of the code of ethics definition enumerated in paragraph (a)(2) of this instruction. The Registrant must file a copy of any such amendment as an exhibit to this report on Form N-CEN, unless the Registrant has elected to satisfy paragraph (a)(6) of this instruction by posting its code of ethics on its website pursuant to paragraph (a)(6)(ii) of this Instruction, or by undertaking to provide its code of ethics to any person without charge, upon request, pursuant to paragraph (a)(6)(iii) of this instruction.

(4) If the Registrant has, during the period covered by the report, granted a waiver, including an implicit waiver, from a provision of the code of ethics to the Registrant's principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, regardless of whether these individuals are employed by the Registrant or a third party, that relates to one or more of the items set forth in paragraph (a)(2) of this instruction, the Registrant must briefly describe the nature of the waiver, the name of the person to whom the waiver was granted, and the date of the waiver.

(7) A Registrant may have separate codes of ethics for different types of officers. Furthermore, a "code of ethics" within the meaning of paragraph (a)(2) of this instruction may be a portion of a broader document that addresses additional topics or that applies to more persons than those specified in paragraph (a)(1) of this instruction. In satisfying the requirements of paragraph (a)(6) of this instruction, a Registrant need only file, post, or provide the portions of a broader document that constitutes a "code of ethics" as defined in paragraph (a)(2) of this instruction and that apply to the persons specified in paragraph (a)(1) of this instruction.

(8) If a Registrant elects to satisfy paragraph (a)(6) of this instruction by posting its code of ethics on its Internet website pursuant to paragraph (a)(6)(ii), the code of ethics must remain accessible on its website for as long as the Registrant remains subject to the requirements of this instruction and chooses to comply with this instruction by posting its code on its Internet website pursuant to paragraph (a)(6)(ii).

If the amendment or waiver occurs on a Saturday, Sunday, or holiday on which the Commission is not open for business, then the five business day period shall begin to run on and include the first business day thereafter. If the Registrant elects to disclose this information through its website, such information must remain available on the website for at least a 12-month period. The Registrant must retain the information for a period of not less than six years following the end of the fiscal year in which the amendment or waiver occurred. Upon request, the Registrant must furnish to the Commission or its staff a copy of any or all information retained pursuant to this requirement.

(10) The Registrant does not need to disclose technical, administrative, or other non-substantive amendments to its code of ethics.

(b) (1) Disclose that the Registrant's board of directors has determined that the Registrant either: (i) has at least one audit committee financial expert serving on its audit committee; or (ii) does not have an audit committee financial expert serving on its audit committee.

(2) If the Registrant provides the disclosure required by paragraph (b)(1)(i) of this instruction, it must disclose the name of the audit committee financial expert and whether that person is "independent."

(4) If the Registrant's board of directors has determined that the Registrant has more than one audit committee financial expert serving on its audit committee, the Registrant may, but is not required to, disclose the names of those additional persons. A Registrant choosing to identify such persons must indicate whether they are independent pursuant to paragraph (b)(2) of this instruction.

(5) For purposes of this instruction, an "audit committee financial expert" means a person who has the following attributes: (i) an understanding of generally accepted accounting principles and financial statements; (ii) the ability to assess the general application of such principles in connection with the accounting for estimates, accruals, and reserves; (iii) experience preparing, auditing, analyzing, or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Registrant's financial statements, or experience actively supervising one or more persons engaged in such activities; (iv) an understanding of internal controls and procedures for financial reporting; and (v) an understanding of audit committee functions.

(6) A person shall have acquired such attributes through: (i) education and experience as a principal financial officer, principal accounting officer, controller, public accountant, or auditor or experience in one or more positions that involve the performance of similar functions; (ii) experience actively supervising a principal financial officer, principal accounting officer, controller, public accountant, auditor, or person performing similar functions; (iii) experience overseeing or assessing the performance of companies or public accountants with respect to the preparation, auditing, or evaluation of financial statements; or (iv) other relevant experience.
