SECTION 8   OTHER EVENTS

ITEM 8.01   OTHER EVENTS.

           Effective December 31, 2005, Viacom Inc. ("former Viacom") separated
into CBS Corporation (the "Registrant") and new Viacom Inc. In accordance with
Statement of Financial Accounting Standards 142, "Goodwill and Other Intangible
Assets" ("SFAS 142"), during the fourth quarter of 2005 the Registrant tests for
impairment of goodwill and intangible assets for all of the businesses of former
Viacom. Based on the preliminary results of the 2005 SFAS 142 impairment test,
the Registrant expects to record in the fourth quarter of 2005 results a
material non-cash charge to reduce the carrying amount of goodwill and
intangible assets of the Registrant to their estimated fair values, which
reflect industry trends and the current marketplace. Substantially all of the
goodwill and intangible assets were established as a result of the 2000 former
Viacom/CBS merger.
