Report of Independent Registered Public Accounting Firm

To the Shareholders and
Board of Trustees of Nuveen Funds

In planning and performing our audit of the financial statements of
each of the Nuveen Funds listed in Exhibit A attached hereto  (the
 Funds ) as of and for the year ended March 31, 2009, 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 companys 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 companys 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/trustees of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized
acquisition, use or disposition of a companys 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 companys 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 their operation, including controls over
safeguarding securities, that we consider to be a material weakness as
defined above as of March 31, 2009.

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.
