In planning and performing our audits of the financial statements of the Funds listed in Appendix A

(hereafter referred to as the “Funds”) as of and for the periods ended October 31, 2021, in accordance with

the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), we

considered the Funds’ internal control over financial reporting, including controls over safeguarding

securities, as a basis for designing our auditing procedures for the purpose of expressing our opinion on

the financial statements and to comply with the requirements of Form N-CEN, but not for the purpose of

expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting.

Accordingly, we do not express an opinion on the effectiveness of the Funds’ internal control over financial reporting.

The management of the Funds is responsible for establishing and maintaining effective internal control

over financial reporting. In fulfilling this responsibility, estimates and judgments by management are

required to assess the expected benefits and related costs of controls. A company’s internal control over

financial reporting is a process designed to provide reasonable assurance regarding the reliability of

financial reporting and the preparation of financial statements for external purposes in accordance with

generally accepted accounting principles. A company’s internal control over financial reporting includes

those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,

accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide

reasonable assurance that transactions are recorded as necessary to permit preparation of financial

statements in accordance with generally accepted accounting principles, and that receipts and

expenditures of the company are being made only in accordance with authorizations of management and

directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection

of unauthorized acquisition, use or disposition of a company’s assets that could have a material effect on

the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect

misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk

that controls may become inadequate because of changes in conditions, or that the degree of compliance

with the policies or procedures may deteriorate.

A deficiency in internal control over financial reporting exists when the design or operation of a control

does not allow management or employees, in the normal course of performing their assigned functions, to

prevent or detect misstatements on a timely basis. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or

detected on a timely basis.

Our consideration of the Funds’ internal control over financial reporting was for the limited purpose

described in the first paragraph and would not necessarily disclose all deficiencies in internal control over

financial reporting that might be material weaknesses under standards established by the PCAOB.

However, we noted no deficiencies in the Funds’ internal control over financial reporting and its

operation, including controls over safeguarding securities, that we consider to be a material weakness as

defined above as of October 31, 2021.
