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 February 28, 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 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 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 its operation, including controls over
safeguarding securities that we consider to be a material weakness as
defined above as of February 28, 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.
