(Reuters) - The all-stock merger of CBS Corp CBS.N and Viacom Inc VIAB.O is expected to close on Dec. 4, the companies said on Monday.

Shares of the combined company, which would be renamed as ViacomCBS Inc, are expected to start trading on Nasdaq from Dec.5 under the new ticker symbols “VIACA” and “VIAC”, the companies said.

Earlier in August, CBS and Viacom agreed to merge, creating a company with more than $28 billion in revenue, as an increasingly competitive media landscape prompted their controlling shareholder to reunify the U.S. entertainment companies 13 years after breaking them up.

The two companies are controlled by National Amusements Inc, the holding company owned by billionaire Sumner Redstone and his family.
