GENERAL AGREEMENTS

A.        ADDITIONAL OFFICES OR EMPLOYEES—CONSOLIDATION OR MERGER—NOTICE

1.     Except as provided in paragraph 2 below, this Bond shall apply to any additional office(s) established by the Insured during the Bond Period and to all Employees during the Bond Period, without the need to give notice thereof or pay additional premiums to the Underwriter for the Bond Period.

2.     If during the Bond Period an Insured Investment Company shall merge or consolidate with an institution in which such Insured is the surviving entity, or purchase substantially all the assets or capital stock of another institution, or acquire or create a separate investment portfolio, and shall within sixty (60) days notify the Underwriter thereof, then this Bond shall automatically apply to the Property and Employees resulting from such merger, consolidation, acquisition or creation from the date thereof; provided, that the Underwriter may make such coverage contingent upon the payment of an additional premium.

B.        WARRANTY

No statement made by or on behalf of the Insured, whether contained in the Application or otherwise, shall be deemed to be an absolute warranty, but only a warranty that such statement is true to the best of the knowledge of the person responsible for such statement.

5

C.        COURT COSTS AND ATTORNEYS’ FEES

The Underwriter will indemnify the Insured against court costs and reasonable attorneys’ fees incurred and paid by the Insured in defense of any legal proceeding brought against the Insured seeking recovery for any loss which, if established against the Insured, would constitute a loss covered under the terms of this Bond; provided, however, that with respect to Insuring Agreement A this indemnity shall apply only in the event that:

1.     an Employee admits to having committed or is adjudicated to have committed a Dishonest or Fraudulent Act which caused the loss; or

2.     in the absence of such an admission or adjudication, an arbitrator or arbitrators acceptable to the Insured and the Underwriter concludes, after a review of an agreed statement of facts, that an Employee has committed a Dishonest or Fraudulent Act which caused the loss.

The Insured shall promptly give notice to the Underwriter of any such legal proceeding and upon request shall furnish the Underwriter with copies of all pleadings and other papers therein. At the Underwriter’s election the Insured shall permit the Underwriter to conduct the defense of such legal proceeding in the Insured’s name, through attorneys of the Underwriter’s selection. In such event, the Insured shall give all reasonable information and assistance which the Underwriter shall deem necessary to the proper defense of such legal proceeding.

If the amount of the Insured’s liability or alleged liability in any such legal proceeding is greater than the amount which the Insured would be entitled to recover under this Bond (other than pursuant to this General Agreement C), or if a Deductible Amount is applicable, or both, the indemnity liability of the Underwriter under this General Agreement C is limited to the proportion of court costs and attorneys’ fees incurred and paid by the Insured or by the Underwriter that the amount which the Insured would be entitled to recover under this Bond (other than pursuant to this General Agreement C) bears to the sum of such amount plus the amount which the Insured is not entitled to recover. Such indemnity shall be in addition to the Limit of Liability for the applicable Insuring Agreement.

D.        INTERPRETATION

This Bond shall be interpreted with due regard to the purpose of fidelity bonding under Rule 17g-1 under the Investment Company Act of 1940 (i.e., to protect innocent third parties from harm) and to the structure of the investment management industry (in which a loss of Property resulting from a cause described in any Insuring Agreement ordinarily gives rise to a potential legal liability on the part of the Insured), such that the term “loss” as used herein shall include an Insured’s legal liability for direct compensatory damages resulting directly from a misappropriation, or measurable diminution in value, of Property.

Upon payment to the Insured hereunder for any loss, the Underwriter shall be subrogated to the extent of such payment to all of the Insured’s rights and claims in connection with such loss; provided, however, that the Underwriter shall not be subrogated to any such rights or claims one named Insured under this Bond may have against another named Insured under this Bond. At the request of the Underwriter, the Insured shall execute all assignments or other documents and take such action as the Underwriter may deem necessary or desirable to secure and perfect such rights and claims, including the execution of documents necessary to enable the Underwriter to bring suit in the name of the Insured.

13

Assignment of any rights or claims under this Bond shall not bind the Underwriter without the Underwriter’s written consent.

SECTION 4. LOSS—NOTICE—PROOF—LEGAL PROCEEDINGS

This Bond is for the use and benefit only of the Insured and the Underwriter shall not be liable hereunder to anyone other than the Insured. As soon as practicable and not more than sixty (60) days after discovery of any loss covered hereunder, the Insured shall give the Underwriter written notice thereof and, as soon as practicable and within one year after such discovery, shall also furnish to the Underwriter affirmative proof of loss with full particulars. The Underwriter may extend the sixty-day notice period or the one-year proof of loss period if the Insured requests an extension and shows good cause therefor.

The Insured shall provide the Underwriter with such information, assistance, and cooperation as the Underwriter may reasonably request.

See also General Agreement C (Court Costs and Attorneys’ Fees).

The Underwriter shall not be liable hereunder for loss of Securities unless each of the Securities is identified in such proof of loss by a certificate or bond number or by such identification means as the Underwriter may require. The Underwriter shall have a reasonable period after receipt of a proper affirmative proof of loss within which to investigate the claim, but where the Property is Securities and the loss is clear and undisputed, settlement shall be made within forty-eight (48) hours even if the loss involves Securities of which duplicates may be obtained.

The Insured shall not bring legal proceedings against the Underwriter to recover any loss hereunder prior to sixty (60) days after filing such proof of loss or subsequent to twenty-four (24) months after the discovery of such loss or, in the case of a legal proceeding to recover hereunder on account of any judgment against the Insured in or settlement of any suit mentioned in General Agreement C or to recover court costs or attorneys’ fees paid in any such suit, twenty-four (24) months after the date of the final judgment in or settlement of such suit. If any limitation in this Bond is prohibited by any applicable law, such limitation shall be deemed to be amended to be equal to the minimum period of limitation permitted by such law.

Notice hereunder shall be given to Manager, Professional Liability Claims, ICI Mutual Insurance Company, RRG, 1401 H St. NW, Washington, DC 20005.

SECTION 5. DISCOVERY

For all purposes under this Bond, a loss is discovered, and discovery of a loss occurs, when the Insured

(1)     becomes aware of facts, or

(2)     receives notice of an actual or potential claim by a third party which alleges that the Insured is liable under circumstances,

which would cause a reasonable person to assume that a loss of a type covered by this Bond has been or is likely to be incurred, regardless of when the act or acts causing or contributing to such loss occurred, even though the exact amount or details of the loss may not be known.

14

SECTION 6. VALUATION OF PROPERTY

For the purpose of determining the amount of any loss hereunder, the value of any Property shall be the market value of such Property at the close of business on the first business day before the discovery of such loss; except that

(1)     the value of any Property replaced by the Insured prior to the payment of a claim therefor shall be the actual market value of such Property at the time of replacement, but not in excess of the market value of such Property on the first business day before the discovery of the loss of such Property;

(2)     the value of Securities which must be produced to exercise subscription, conversion, redemption or deposit privileges shall be the market value of such privileges immediately preceding the expiration thereof if the loss of such Securities is not discovered until after such expiration, but if there is no quoted or other ascertainable market price for such Property or privileges referred to in clauses (1) and (2), their value shall be fixed by agreement between the parties or by arbitration before an arbitrator or arbitrators acceptable to the parties; and

(3)     the value of books of accounts or other records used by the Insured in the conduct of its business shall be limited to the actual cost of blank books, blank pages or other materials if the books or records are reproduced plus the cost of labor for the transcription or copying of data furnished by the Insured for reproduction.

SECTION 7. LOST SECURITIES

The maximum liability of the Underwriter hereunder for lost Securities shall be the payment for, or replacement of, such Securities having an aggregate value not to exceed the applicable Limit of Liability. If the Underwriter shall make payment to the Insured for any loss of Securities, the Insured shall assign to the Underwriter all of the Insured’s right, title and interest in and to such Securities. In lieu of such payment, the Underwriter may, at its option, replace such lost Securities, and in such case the Insured shall cooperate to effect such replacement. To effect the replacement of lost Securities, the Underwriter may issue or arrange for the issuance of a lost instrument bond. If the value of such Securities does not exceed the applicable Deductible Amount (at the time of the discovery of the loss), the Insured will pay the usual premium charged for the lost instrument bond and will indemnify the issuer of such bond against all loss and expense that it may sustain because of the issuance of such bond.

If the value of such Securities exceeds the applicable Deductible Amount (at the time of discovery of the loss), the Insured will pay a proportion of the usual premium charged for the lost instrument bond, equal to the percentage that the applicable Deductible Amount bears to the value of such Securities upon discovery of the loss, and will indemnify the issuer of such bond against all loss and expense that is not recovered from the Underwriter under the terms and conditions of this Bond, subject to the applicable Limit of Liability.

SECTION 8. SALVAGE

If any recovery is made, whether by the Insured or the Underwriter, on account of any loss within the applicable Limit of Liability hereunder, the Underwriter shall be entitled to the full amount of such recovery to reimburse the Underwriter for all amounts paid hereunder with respect to such loss. If any recovery is made, whether by the Insured or the Underwriter, on account of any loss in excess of the applicable Limit of Liability hereunder plus the Deductible Amount applicable to such loss from any source other than suretyship, insurance, reinsurance, security or indemnity taken by or for the benefit of the Underwriter, the amount of such recovery, net of the actual costs and expenses of recovery, shall

15

be applied to reimburse the Insured in full for the portion of such loss in excess of such Limit of Liability, and the remainder, if any, shall be paid first to reimburse the Underwriter for all amounts paid hereunder with respect to such loss and then to the Insured to the extent of the portion of such loss within the Deductible Amount. The Insured shall execute all documents which the Underwriter deems necessary or desirable to secure to the Underwriter the rights provided for herein.

SECTION 9.        NON-REDUCTION AND NON-ACCUMULATION OF LIABILITY AND TOTAL LIABILITY

Prior to its termination, this Bond shall continue in force up to the Limit of Liability for each Insuring Agreement for each Single Loss, notwithstanding any previous loss (other than such Single Loss) for which the Underwriter may have paid or be liable to pay hereunder; PROVIDED, however, that regardless of the number of years this Bond shall continue in force and the number of premiums which shall be payable or paid, the liability of the Underwriter under this Bond with respect to any Single Loss shall be limited to the applicable Limit of Liability irrespective of the total amount of such Single Loss and shall not be cumulative in amounts from year to year or from period to period.

SECTION 10.      MAXIMUM LIABILITY OF UNDERWRITER; OTHER BONDS OR POLICIES

The maximum liability of the Underwriter for any Single Loss covered by any Insuring Agreement under this Bond shall be the Limit of Liability applicable to such Insuring Agreement, subject to the applicable Deductible Amount and the other provisions of this Bond. Recovery for any Single Loss may not be made under more than one Insuring Agreement. If any Single Loss covered under this Bond is recoverable or recovered in whole or in part because of an unexpired discovery period under any other bonds or policies issued by the Underwriter to the Insured or to any predecessor in interest of the Insured, the maximum liability of the Underwriter shall be the greater of either (1) the applicable Limit of Liability under this Bond, or (2) the maximum liability of the Underwriter under such other bonds or policies.

SECTION 11.      OTHER INSURANCE

Notwithstanding anything to the contrary herein, if any loss covered by this Bond shall also be covered by other insurance or suretyship for the benefit of the Insured, the Underwriter shall be liable hereunder only for the portion of such loss in excess of the amount recoverable under such other insurance or suretyship, but not exceeding the applicable Limit of Liability of this Bond.

SECTION 12.      DEDUCTIBLE AMOUNT

The Underwriter shall not be liable under any Insuring Agreement unless the amount of the loss covered thereunder, after deducting the net amount of all reimbursement and/or recovery received by the Insured with respect to such loss (other than from any other bond, suretyship or insurance policy or as an advance by the Underwriter hereunder) shall exceed the applicable Deductible Amount; in such case the Underwriter shall be liable only for such excess, subject to the applicable Limit of Liability and the other terms of this Bond.

No Deductible Amount shall apply to any loss covered under Insuring Agreement A sustained by any Investment Company named as an Insured.

16

SECTION 13.      TERMINATION

The Underwriter may terminate this Bond as to any Insured or all Insureds only by written notice to such Insured or Insureds and, if this Bond is terminated as to any Investment Company, to each such Investment Company terminated thereby and to the Securities and Exchange Commission, Washington, D.C., in all cases not less than sixty (60) days prior to the effective date of termination specified in such notice.

The Insured may terminate this Bond only by written notice to the Underwriter not less than sixty (60) days prior to the effective date of the termination specified in such notice. Notwithstanding the foregoing, when the Insured terminates this Bond as to any Investment Company, the effective date of termination shall be not less than sixty (60) days from the date the Underwriter provides written notice of the termination to each such Investment Company terminated thereby and to the Securities and Exchange Commission, Washington, D.C.

This Bond will terminate as to any Insured that is a Non-Fund immediately and without notice upon (1) the takeover of such Insured’s business by any State or Federal official or agency, or by any receiver or liquidator, or (2) the filing of a petition under any State or Federal statute relative to bankruptcy or reorganization of the Insured, or assignment for the benefit of creditors of the Insured.

Premiums are earned until the effective date of termination. The Underwriter shall refund the unearned premium computed at short rates in accordance with the Underwriter’s standard short rate cancellation tables if this Bond is terminated by the Insured or pro rata if this Bond is terminated by the Underwriter.

Upon the detection by any Insured that an Employee has committed any Dishonest or Fraudulent Act(s), the Insured shall immediately remove such Employee from a position that may enable such Employee to cause the Insured to suffer a loss by any subsequent Dishonest or Fraudulent Act(s). The Insured, within two (2) business days of such detection, shall notify the Underwriter with full and complete particulars of the detected Dishonest or Fraudulent Act(s).

For purposes of this section, detection occurs when any partner, officer, or supervisory employee of any Insured, who is not in collusion with such Employee, becomes aware that the Employee has committed any Dishonest or Fraudulent Act(s).

This Bond shall terminate as to any Employee by written notice from the Underwriter to each Insured and, if such Employee is an Employee of an Insured Investment Company, to the Securities and Exchange Commission, in all cases not less than sixty (60) days prior to the effective date of termination specified in such notice.

SECTION 14.      RIGHTS AFTER TERMINATION

At any time prior to the effective date of termination of this Bond as to any Insured, such Insured may, by written notice to the Underwriter, elect to purchase the right under this Bond to an additional period of twelve (12) months within which to discover loss sustained by such Insured prior to the effective date of such termination and shall pay an additional premium therefor as the Underwriter may require.

Such additional discovery period shall terminate immediately and without notice upon the takeover of such Insured’s business by any State or Federal official or agency, or by any receiver or liquidator. Promptly after such termination the Underwriter shall refund to the Insured any unearned premium.

17

The right to purchase such additional discovery period may not be exercised by any State or Federal official or agency, or by any receiver or liquidator, acting or appointed to take over the Insured’s business.

SECTION 15.      CENTRAL HANDLING OF SECURITIES

The Underwriter shall not be liable for loss in connection with the central handling of securities within the systems established and maintained by any Depository (“Systems”), unless the amount of such loss exceeds the amount recoverable or recovered under any bond or policy or participants’ fund insuring the Depository against such loss (the “Depository’s Recovery”); in such case the Underwriter shall be liable hereunder only for the Insured’s share of such excess loss, subject to the applicable Limit of Liability, the Deductible Amount and the other terms of this Bond.

For determining the Insured’s share of such excess loss, (1) the Insured shall be deemed to have an interest in any certificate representing any security included within the Systems equivalent to the interest the Insured then has in all certificates representing the same security included within the Systems; (2) the Depository shall have reasonably and fairly apportioned the Depository’s Recovery among all those having an interest as recorded by appropriate entries in the books and records of the Depository in Property involved in such loss, so that each such interest shall share in the Depository’s Recovery in the ratio that the value of each such interest bears to the total value of all such interests; and (3) the Insured’s share of such excess loss shall be the amount of the Insured’s interest in such Property in excess of the amount(s) so apportioned to the Insured by the Depository.

This Bond does not afford coverage in favor of any Depository or Exchange or any nominee in whose name is registered any security included within the Systems.

SECTION 16.      ADDITIONAL COMPANIES INCLUDED AS INSURED

If more than one entity is named as the Insured:

A.    the total liability of the Underwriter hereunder for each Single Loss shall not exceed the Limit of Liability which would be applicable if there were only one named Insured, regardless of the number of Insured entities which sustain loss as a result of such Single Loss,

B.    the Insured first named in Item 1 of the Declarations shall be deemed authorized to make, adjust, and settle, and receive and enforce payment of, all claims hereunder as the agent of each other Insured for such purposes and for the giving or receiving of any notice required or permitted to be given hereunder; provided, that the Underwriter shall promptly furnish each named Insured Investment Company with (1) a copy of this Bond and any amendments thereto, (2) a copy of each formal filing of a claim hereunder by any other Insured, and (3) notification of the terms of the settlement of each such claim prior to the execution of such settlement,

C.    the Underwriter shall not be responsible or have any liability for the proper application by the Insured first named in Item 1 of the Declarations of any payment made hereunder to the first named Insured,

D.    for the purposes of Sections 4 and 13, knowledge possessed or discovery made by any partner, officer or supervisory Employee of any Insured shall constitute knowledge or discovery by every named Insured,

18

E.    if the first named Insured ceases for any reason to be covered under this Bond, then the Insured next named shall thereafter be considered as the first named Insured for the purposes of this Bond, and

F.     each named Insured shall constitute “the Insured” for all purposes of this Bond.

SECTION 17.      NOTICE AND CHANGE OF CONTROL

Within thirty (30) days after learning that there has been a change in control of an Insured by transfer of its outstanding voting securities the Insured shall give written notice to the Underwriter of:

A.    the names of the transferors and transferees (or the names of the beneficial owners if the voting securities are registered in another name), and

B.    the total number of voting securities owned by the transferors and the transferees (or the beneficial owners), both immediately before and after the transfer, and

C.    the total number of outstanding voting securities.

As used in this Section, “control” means the power to exercise a controlling influence over the management or policies of the Insured.

SECTION 18.      CHANGE OR MODIFICATION

This Bond may only be modified by written Rider forming a part hereof over the signature of the Underwriter’s authorized representative. Any Rider which modifies the coverage provided by Insuring Agreement A, Fidelity, in a manner which adversely affects the rights of an Insured Investment Company shall not become effective until at least sixty (60) days after the Underwriter has given written notice thereof to the Securities and Exchange Commission, Washington, D.C., and to each Insured Investment Company affected thereby.

SECTION 19.      COMPLIANCE WITH APPLICABLE TRADE AND ECONOMIC SANCTIONS

This Bond shall not be deemed to provide any coverage, and the Underwriter shall not be required to pay any loss or provide any benefit hereunder, to the extent that the provision of such coverage, payment of such loss or provision of such benefit would cause the Underwriter to be in violation of any applicable trade or economic sanctions, laws or regulations, including, but not limited to, any sanctions, laws or regulations administered and enforced by the U.S. Department of Treasury Office of Foreign Assets Control (OFAC).

SECTION 20.      ANTI-BUNDLING

If any Insuring Agreement requires that an enumerated type of document be Counterfeit, or contain a Forgery or Alteration, the Counterfeit, Forgery, or Alteration must be on or of the enumerated document itself, not on or of some other document submitted with, accompanying or incorporated by reference into the enumerated document.

IN WITNESS WHEREOF, the Underwriter has caused this Bond to be executed on the Declarations Page.

J.     COMPUTER SECURITY

Loss (including loss of Property) resulting directly from Computer Fraud; provided, that the Insured has adopted in writing and generally maintains and follows during the Bond Period all Computer Security Procedures. The isolated failure of the Insured to maintain and follow a particular Computer Security Procedure in a particular instance will not preclude coverage under this Insuring Agreement, subject to the specific exclusions herein and in the Bond.

1.              Definitions. The following terms used in this Insuring Agreement shall have the following meanings:

a.              “Authorized User” means any person or entity designated by the Insured (through contract, assignment of User Identification, or otherwise) as authorized to use a Covered Computer System, or any part thereof. An individual who invests in an Insured Fund shall not be considered to be an Authorized User solely by virtue of being an investor.

b.              “Computer Fraud” means the unauthorized entry of data into, or the deletion or destruction of data in, or change of data elements or programs within, a Covered Computer System which:

(1)                     is committed by any Unauthorized Third Party anywhere, alone or in collusion with other Unauthorized Third Parties; and

(2)                     is committed with the conscious manifest intent (a) to cause the Insured to sustain a loss, and (b) to obtain financial benefit for the perpetrator or any other person; and

(3)                     causes (x) Property to be transferred, paid or delivered; or (y) an account of the Insured, or of its customer, to be added, deleted, debited or credited; or (z) an unauthorized or fictitious account to be debited or credited.

c.               “Computer Security Procedures” means procedures for prevention of unauthorized computer access and use and administration of computer access and use as provided in writing to the Underwriter.

d.              “Covered Computer System” means any Computer System as to which the Insured has possession, custody and control.

e.               “Unauthorized Third Party” means any person or entity that, at the time of the Computer Fraud, is not an Authorized User.

f.                “User Identification” means any unique user name (i.e., a series of characters) that is assigned to a person or entity by the Insured.

2.              Exclusions. It is further understood and agreed that this Insuring Agreement J shall not cover:

a.              Any loss covered under Insuring Agreement A, “Fidelity,” of this Bond; and

b.              Any loss resulting from the intentional failure to adhere to one or more Computer Security Procedures; and

c.               Any loss resulting from a Computer Fraud committed by or in collusion with:

(1)                     any Authorized User (whether a natural person or an entity); or

(2)                     in the case of any Authorized User which is an entity, (a) any director, officer, partner, employee or agent of such Authorized User, or (b) any entity which controls, is controlled by, or is under common control with such Authorized User (“Related Entity”), or (c) any director, officer, partner, employee or agent of such Related Entity; or

(3)                     in the case of any Authorized User who is a natural person, (a) any entity for which such Authorized User is a director, officer, partner, employee or agent (“Employer Entity”), or (b) any director, officer, partner, employee or agent of such Employer Entity, or (c) any entity which controls, is controlled by, or is under common control with such Employer Entity (“Employer-Related Entity”), or (d) any director, officer, partner, employee or agent of such Employer-Related Entity;

and

d.              Any loss resulting from physical damage to or destruction of any Covered Computer System, or any part thereof, or any data, data elements or media associated therewith; and

e.               Any loss not directly and proximately caused by Computer Fraud (including, without limitation, disruption of business and extra expense); and

f.                Payments made to any person(s) who has threatened to deny or has denied authorized access to a Covered Computer System or otherwise has threatened to disrupt the business of the Insured.

For purposes of this Insuring Agreement, “Single Loss,” as defined in Section 1.EE of this Bond, shall also include all loss caused by Computer Fraud(s) committed by one person, or in which one person is implicated, whether or not that person is specifically identified. A series of losses involving unidentified individuals, but arising from the same method of operation, may be deemed by the Underwriter to involve the same individual and in that event shall be treated as a Single Loss.

It is further understood and agreed that nothing in this Rider shall affect the exclusion set forth in Section 2.O of this Bond.

Coverage under this Insuring Agreement shall terminate upon termination of this Bond. Coverage under this Insuring Agreement may also be terminated without terminating this Bond as an entirety:

(a)                     by written notice from the Underwriter not less than sixty (60) days prior to the effective date of termination specified in such notice; or

(b)                     immediately by written notice from the Insured to the Underwriter.

Except as above stated, nothing herein shall be held to alter, waive or extend any of the terms of this Bond.

RIDER NO. 12

Most property and casualty insurers, including ICI Mutual Insurance Company, a Risk Retention Group (“ICI Mutual”), are subject to the requirements of the Terrorism Risk Insurance Act of 2002, as amended (the “Act”). The Act establishes a federal insurance backstop under which ICI Mutual and these other insurers may be partially reimbursed by the United States Government for future “insured losses” resulting from certified “acts of terrorism.” (Each of these bolded terms is defined by the Act.) The Act also places certain disclosure and other obligations on ICI Mutual and these other insurers.

Pursuant to the Act, any future losses to ICI Mutual caused by certified “acts of terrorism” may be partially reimbursed by the United Sates government under a formula established by the Act. Under this formula, the United States government would generally reimburse ICI Mutual for the Federal Share of Compensation of ICI Mutual’s “insured losses” in excess of ICI Mutual’s “insurer deductible” until total “insured losses” of all participating insurers reach $100 billion (the “Cap on Annual Liability”). If total “insured losses” of all property and casualty insurers reach the Cap on Annual Liability in any one calendar year, the Act limits U.S. Government reimbursement and provides that the insurers will not be liable under their policies for their portions of such losses that exceed such amount. Amounts otherwise payable under this Bond may be reduced as a result.

This Bond has no express exclusion for “acts of terrorism.” However, coverage under this Bond remains subject to all applicable terms, conditions, and limitations of the Bond (including exclusions) that are permissible under the Act.

The portion of the premium that is attributable to any coverage potentially available under the Bond for “acts of terrorism” is one percent (1%) and does not include any charges for the portion of loss that may be covered by the U.S. Government under the Act

As used herein, “Federal Share of Compensation” shall mean 80% beginning on January 1, 2020.

Except as above stated, nothing herein shall be held to alter, waive or extend any of the terms of this Bond.

The premium on the bond has been paid for the period ending March 31, 2022.  In addition, please note that the minimum amount of bond that each trust would have been required to provide, as set forth in Rule 17g-1(d), under a single insured bond is as follows:

FIDELITY BOND INSURANCE ALLOCATION AGREEMENT

This Agreement is dated as of March 24, 2021 and is entered into by and among:

(each of such parties being referred to individually as a “Party” and collectively as the “Parties”).

In order to obtain joint-insureds fidelity bond insurance under an insurance policy (the “Policy”) on favorable terms, and in consideration of the mutual agreements set forth below, the Parties agree as follows:

1.             The Policy.  The Parties agree to secure and maintain a Policy, which will insure each Party and, if such Party is an investment company (an “investment company”) registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”), its respective portfolios.

2.             Primary Coverage.  Each Party shall have “Primary Coverage” (i.e. minimum insured coverage) under the Policy, under which they are insured, as set forth in the Schedule to this Agreement, which Schedule may be amended from time to time by the Parties.  Each Party who is an investment company shall have Primary Coverage in an amount at least equal to the amount required by applicable laws and regulations.  This Agreement applies to the initial Policy and any future insurance policy insuring the same Insureds, all as modified from time to time. Each

Party shall promptly take action to increase its Primary Coverage amount, which shall therefore increase the total amount (i.e. limit of liability) of the Policy, whenever required to comply with applicable federal statutes and regulations, including but not limited to Rule 17g-1 under the Investment Company Act.

3.             Definitions.  As used in this Agreement, the following terms have the following meanings:

(a)           “Agent” means Calamos Advisors or its successor, acting as agent for the Parties.

(b)           “Commission” means the Securities and Exchange Commission.

(c)           “Insured” means, a Party and, for investment companies, any portfolio of any Party and “Insureds” means all Parties and all portfolios of the Parties.

(d)           “Insured Loss” means a loss (including all related expenses) of an Insured that is covered under the Policy (including any endorsement thereof) or that would be so covered but for the exhaustion of the applicable limit of liability and any applicable deductible.

(e)           “Policy Period” means the period from the initial effective date of the Policy through the next succeeding anniversary date or the period from any anniversary date subsequent to the initial effective date through the next succeeding anniversary date (or any modification of such period as may be agreed to by the Parties and the insurer).

4.             Allocation of Premiums.  Each Party shall pay that portion of the Policy premium for any Policy Period equal to (i) the underwriter’s estimate of relative cost to that Insured of a single-insured policy providing coverage similar to such policy but in an amount equal to the Primary Coverage allocated to that Insured under this Agreement, as such amount may be amended from time to time, in relation to (ii) the aggregate of the cost to all Insureds of such single-insured policies.

5.             Allocation of Coverages.  The Policy is a “claims made” policy.  Proceeds paid under the Policy shall be allocated among the Insureds as follows.

(a)           Coverage Sufficient for All Insured Losses.  If the aggregate Insured Losses of all Insureds relating to claims with respect to a particular Policy Period are covered by proceeds of the Policy for that Policy Period, such proceeds shall be allocated among the Insureds according to their respective Insured Losses.

(b)           Allocation of Insufficient Coverage.  If the aggregate Insured Losses of all Insureds relating to claims with respect to a particular Policy Period exceed the aggregate proceeds of the Policy for Insured Losses for that Policy Period, such proceeds shall be first allocated among the Insureds who sustained such losses in proportion to their respective Primary Coverages; and if, after such initial allocation, there are remaining proceeds for Insured Losses relating to that Policy Period, such remaining proceeds shall be further allocated among such Insureds whose Insured Losses have not yet been paid in proportion to such respective Primary Coverages of those Insureds (repeating this further allocation procedure until all of such proceeds have been allocated).

(c)           Reallocation.  If all Insured Losses relating to a Policy Period under the Policy are not paid at the same time, the Insureds who claim such Insured Losses for that Policy Period shall make such provisions as they deem suitable to the particular circumstances (taking into account the size of any payments received, the size, nature and expected result of any remaining claims, and all other relevant factors) to permit a later reallocation of amounts first paid in accordance with this section 5.

6.             Notices.  Each Insured agrees promptly to give to the Insurer all notices required under the Policy.

7.             Agent.  The Agent is hereby appointed as the agent for the Insureds for the purposes of seeking, negotiating and obtaining the Policy and of making, adjusting, receiving and enforcing payment of all claims under the Policy and otherwise dealing with the insurer with respect to the Policy.  All expenses incurred by the Agent in its capacity as agent for claims shall be shared by the Parties and their respective Insureds on whose behalf the expenses were incurred in proportion to their Insured Losses.

8.             Notification of Agent.  Each Party shall promptly notify the Agent in writing of any circumstance that may give rise to a claim by such Party or its Insureds under the Policy.

9.             Filing with the Commission.  Each Party, as required by Rule 17g-1 under Section 17(g) of the Investment Company Act of 1940, shall file a copy of this Agreement and any amendment hereto with the Commission.

10.          Modification and Termination.  This Agreement may be modified or amended from time to time by mutual written agreement among the Parties.  It shall terminate with respect to any Insured as of the date such Insured ceases to be an insured under the Policy; provided that such termination shall not affect that Insured’s rights and obligations hereunder with respect to any claims or Insured Losses relating to a period when that Insured was insured under the Policy.  This Agreement may be terminated by either Party by written notice to the other Party given not less than 60 days prior to the date specified for termination.

11.          Prior Agreements.  This Agreement shall supersede any prior agreement among the Parties relating to the allocation of premiums and coverage under any joint-insured policy bond providing fidelity coverage, and any such agreement is hereby terminated.

12.          Further Assurances.  Each Party agrees to perform such further acts and execute such further documents as are necessary to effect the purposes hereof.
