Item 2.05     Costs Associated with Exit or Disposal Activities.

         On August 31, 2005, Interstate Bakeries Corporation (the "Company")
issued a press release, attached hereto as Exhibit 99.1 and hereby incorporated
by reference, announcing that it plans to close its bakery in Davenport, Iowa,
as part of its nationwide restructuring efforts. The Company notified workers
impacted by the closing on the same date. The Company expects the closing to be
completed by November 4, 2005, subject to bankruptcy court approval. The
closure is expected to affect approximately 150 workers.

         The Company's preliminary estimate of charges to be incurred in
connection with the closure is approximately $5.0 million, including
approximately $1.5 million of severance charges, approximately $2.0 million of
asset impairment charges and approximately $1.5 million in other charges. The
Company further estimates that approximately $3.0 million of such costs will
result in future cash expenditures. In addition, the Company intends to spend
approximately $500,000 in capital expenditures and accrued expenses to effect
the closure.

Item 2.06     Material Impairments.

         The information reported in Item 2.05 "Costs Associated with Exit or
Disposal Activities" is hereby incorporated by reference. The Company's
preliminary estimate of non-cash asset impairment charges to be incurred in
connection with the closure, related primarily to write-downs of machinery,
equipment and real property to their estimated fair values, is approximately
$2.0 million.
