Item 2.05         Costs Associated with Exit or Disposal Activities.

         On April 27, 2005, Interstate Bakeries Corporation (the "Company")
issued a press release, attached hereto as Exhibit 99.1 and hereby incorporated
by reference, announcing that it had committed to a plan, as part of its
previously announced operational and financial restructuring and subject to
bankruptcy court approval, to consolidate operations in its Florida Profit
Center ("PC") by closing its bakery in Miami and consolidating routes, depots
and thrift stores in Florida and Georgia, where it maintains regional
facilities. The Company expects to complete the consolidation of the Florida PC
by July 8, 2005. The closure is expected to affect approximately 600 workers.

         The Company's preliminary estimate of charges to be incurred in
connection with the Florida PC consolidation is approximately $10 million,
including approximately $2 million of severance charges, approximately $5
million of asset impairment charges, and approximately $2 million in other
charges. IBC further estimates that approximately $5 million of such costs will
result in future cash expenditures. In addition, the Company intends to spend
approximately $1 million in capital expenditures and an additional $1 million
in other accrued expenses to effect the consolidation.

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 Florida PC consolidation is approximately $5 million. The
charge relates primarily to write-downs of machinery and equipment to their
estimated fair values.
