Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of
Nuveen Funds

In planning and performing our audits of the financial statements of
each of the Nuveen Funds listed in Exhibit A attached hereto (the
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, 2013.

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.
