ITEM 2.06     MATERIAL IMPAIRMENTS
              --------------------

         On September 16, 2009, the Board of Directors of BCSB Bancorp, Inc.
(the "Company") concluded that during the three months ending September 30,
2009, the Company will record a $2.3 million impairment charge to write off all
goodwill recorded in connection with the Company's 2002 acquisition of WHG
Bancshares Corporation. The goodwill impairment charge is a non-cash adjustment
which has no effect on cash flows, liquidity, tangible capital or regulatory
capital ratios. There will be no tax benefit associated with this charge. The
determination of the impairment followed the Company's annual review of its
goodwill, which was performed by a third party that specializes in these types
of valuations. The goodwill analysis indicated an impairment which was taken
pursuant to generally accepted accounting principles, in particular, Statement
of Financial Accounting Standards No. 142. The impairment is primarily due to
declines in (i) the stock prices of financial institutions comparable to the
Company, and (ii) fair market valuations with respect to mergers and
acquisitions of financial institutions similar to the Company, which occurred
during the goodwill analysis review period. For more information, see the
Company's press release dated September 17, 2009, which is filed as Exhibit 99.1
to this report and incorporated herein by reference.
