Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors/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/period ended February 28,
2011, 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
directors 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 February 28, 2011.

This report is intended solely for the information and use of
management and the Board of Directors/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.
