Item 2.05         Costs Associated with Exit or Disposal Activities.

         On May 19, 2005, Interstate Bakeries Corporation (the "Company")
issued a press release, attached hereto as Exhibit 99.1 and hereby
incorporated by reference, announcing that, as part of its continuing efforts
to address its revenue declines and high-cost structure, it plans to
consolidate operations in its Northeast Profit Center ("PC") by closing its
bakery in New Bedford, Massachusetts, and consolidating production, routes,
depots and thrift stores throughout the Northeast where it maintains regional
facilities. The Company issued Worker Adjustment and Retraining Notification,
or WARN, notices to workers in its New Bedford, Massachusetts bakery on the
same date. The Company expects to complete the consolidation of the Northeast
PC by mid-August, subject to bankruptcy court approval. The consolidation is
expected to affect approximately 1400 workers.

         The Company's preliminary estimate of charges to be incurred in
connection with the Northeast PC consolidation is approximately $17 million,
including approximately $7 million of severance charges, approximately $7
million of asset impairment charges and approximately $3 million in other
charges. IBC further estimates that approximately $9 million of such costs
will result in future cash expenditures. In addition, the Company intends to
spend approximately $4.5 million in capital expenditures and accrued expenses
to effect the consolidation. In addition to the asset impairment charges
discussed above, the Company also expects to recognize charges to intangible
assets related to trademarks and tradenames that will be impaired as a result
of the consolidation of operations announced today. The Company is currently
unable in good faith to make a determination of an estimate of these charges.

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 Northeast PC consolidation, related primarily to
write-downs of machinery, equipment and land and buildings to their estimated
fair values, is approximately $7 million. In addition, the Company also
expects to recognize charges to intangible assets related to trademarks and
tradenames that will be impaired as a result of the consolidation of
operations announced today. The Company is currently unable in good faith to
make a determination of an estimate of these charges.
