Report of Independent Registered Public Accounting Firm

To the Shareholders and
Board of Trustees of
Nuveen Closed End Funds

In planning and performing our audit of the financial statements of each
of the Nuveen Closed End Funds listed in Exhibit A attached hereto (the
Funds) as of and for the year ended March  31, 2010, in accordance
with the standards of the Public Company Accounting Oversight Board
(United States), 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-SAR, but not for the purpose of expressing an opinion on the
effectiveness of the Funds internal control over financial reporting.
Accordingly, we express no such opinion.

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
funds 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 funds
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 fund; (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 fund are being made
only in accordance with authorizations of management and trustees of the
fund; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use or disposition of a funds 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 funds 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 that might be
material weaknesses under standards established by the Public Company
Accounting Oversight Board (United States). 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 March 31,
2010.

This report is intended solely for the information and use of management
and the Board of Trustees of the Funds and the Securities and Exchange
Commission and is not intended to be and should not be used by anyone
other than these specified parties.
