financial results for the quarter ended December 31, 2009, is attached

Item 2.06  Material Impairments

     On May 26, 2010, NASB Financial, Inc. (the "Company") determined
that its investment in Central Platte Holdings, LLC ("Central Platte")
was impaired.  The Company's investment in Central Platte consists of a
50% ownership interest in an entity that develops land for residential
real estate sales.  The Company accounts for its investment in Central
Platte under the equity method.  Sales of lots have not met previous
expectations and, as a result, the Company evaluated its investment for
impairment.  The Company recorded a non-cash impairment charge of $2
million ($1.2 million, net of tax) on its investment in Central Platte
during the quarter ended December 31, 2009.  The Company's investment
in Central Platte, after the impairment charge, is approximately $17
million at December 31, 2009.

     It is not anticipated that the impairment charge will result in
future cash expenditures by the company.
