Item 4.02.  Non-Reliance on Previously Issued Financial Statements or a
Related Audit Report or Completed Interim Review

     On May 6, 2011, NASB Financial, Inc. (the "Company," "we," "us, "
or "our") received a letter from the Office of Thrift Supervision
("OTS"), the regulator of our operating subsidiary, North American
Savings Bank, F.S.B. (the "Bank"), directing us to amend and restate
our financial results for the quarter ended December 31, 2010 ("First
Fiscal Quarter"). The directive to amend and restate our financials
resulted from recent OTS examination findings requiring us to
reclassify certain loan obligations extended by the Bank as troubled
debt restructuring ("TDR").  Upon discussion of these findings and the
OTS directive with our independent registered public accountants, our
Audit Committee and management concluded that the financial statements
of the Company for our First Fiscal Quarter should no longer be relied
upon because of the improper classification noted by the OTS in such
financial statements and that the financial statements for the First
Fiscal Quarter must be restated.  We believe that upon reclassification
of these loans to TDR they will be impaired by an aggregate of
approximately $6.6 million, pre-tax, as of December 31, 2010.

     Subsequent to the filing of our Form 10-Q for the First Fiscal
Quarter, we became aware that certain foreclosed real estate, acquired
as a result of the foreclosure of a participation loan held by us, had
declined in value.  Therefore, in our restated financial statements for
the First Fiscal Quarter we intend to reflect the decrease in value of
this property in the amount of $1.6 million, pre-tax.

     As a result of these restatements, the Company's previously
reported net income for the First Fiscal Quarter of  $2.0 million, or
$0.26 per share, will decrease to a net loss of $3.0 million, or
$(0.39) per share.  The Company intends to amend, as soon as
practicable, the Form 10-Q for the First Fiscal Quarter to reflect
these restatements.

     The following table summarizes the effects of the restatement on
the Company's consolidated statement of income (loss) for the three
months ended December 31, 2010 (dollars in thousands, except per share
data):
