 Our examination was conducted in accordance with attestation
                                                           standards established by the American Institute of Certified Public Accountants. Those standards require that we plan and
                                                           perform the examination to obtain reasonable assurance about whether the Management Assertion about compliance with
                                                           the specified requirements is fairly stated, in all material respects. An examination involves performing procedures to
                                                           obtain evidence about whether the Management Assertion is fairly stated, in all material respects. The nature, timing, and
                                                           extent of the procedures selected depend on our judgment, including an assessment of the risks of material misstatement of
                                                           the Management Assertion, whether due to fraud or error. We believe that the evidence we obtained is sufficient and
                                                           appropriate to provide a reasonable basis for our opinion.  Our examination does not provide a legal determination on the Banks compliance
with specified requirements.
