# Exhibit 99.1
Report of Management on Internal Control over Financial Reporting

Management of Princeton
National Bancorp, Inc. (PNBC) is responsible for establishing and maintaining adequate internal control over financial
reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. PNBCs 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 accounting principles generally accepted in the
United States of America. Internal control over financial reporting includes those policies and procedures that:

| |  |  | pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of PNBC;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United
States of America;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | provide reasonable assurance that receipts and expenditures of
PNBC are being made only in accordance with authorization of management and directors of PNBC; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated
financial statements.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Internal control over
financial reporting includes the controls themselves, monitoring and internal auditing practices and actions taken to correct
deficiencies as identified.

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.

Management assessed the
effectiveness of PNBCs internal control over financial reporting as of December 31, 2005. Management based this assessment
on criteria for effective internal control over financial reporting described in Internal Control-Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission. Managements assessment included an
evaluation of the design of PNBCs internal control over financial reporting and testing of the operational effectiveness of
its internal control over financial reporting. Management reviewed the results of its assessment with the Audit Committee of the
Board of Directors.

Based on this assessment,
management determined that, as of December 31, 2005, PNBC maintained effective internal control over financial reporting.

KPMG LLP, the independent
registered public accounting firm, that audited and reported on the consolidated financial statements of PNBC included in this
report, has issued an attestation report on managements assessment of internal control over financial reporting as of
December 31, 2005.
