March 21 (Reuters) - Australian media firm Nine

Entertainment ( NNMTF ) said on Friday it was in talks with

property data group CoStar ( CSGP ) over a revised offer by the

U.S. company for the former's majority-owned real estate

classifieds firm Domain.

CoStar ( CSGP ) had, in February, offered to buy out Domain in a deal

valuing the company at A$2.65 billion ($1.67 billion).

Nine owns around a 60% stake in Domain.

Domain, in a statement on Friday, confirmed to the market

that it had not received a revised bid from CoStar ( CSGP ) since the

original offer landed. The company did not immediately respond

to a request for comment on whether it is in talks with CoStar ( CSGP )

over a revised proposal.

Domain further confirmed that it continues to assess the

original bid from CoStar ( CSGP ).

Nine, while addressing a media report by the Australian

Financial Review (AFR) on Friday, said it was in talks with

CoStar ( CSGP ) over the original bid and also remains engaged with

Domain.

"Discussions remain confidential and incomplete (including

as to the price at which CoStar ( CSGP ) might make a revised proposal),"

Nine said in an ASX filing.

The AFR reported on Thursday that Nine Entertainment ( NNMTF ) had

begun negotiations to sell its controlling stake in Domain to

CoStar ( CSGP ), with both sides debating a price.

Last month, CoStar ( CSGP ) picked up Domain shares on the

market, acquiring a 16.9% stake before making a cash offer of

A$4.20 per share for the remainder of Australia's second-largest

property listings platform.

Shares in Domain have gained around 39% since they began

trading on February 21, while Nine has added over 10%. Domain

closed trading on Thursday at A$4.34, higher than the A$4.20 bid

by CoStar ( CSGP ).

Nine flagged that there was no certainty as to the talks

leading to a revised proposal from CoStar ( CSGP ).

CoStar ( CSGP ) did not immediately respond to a Reuters request for

comment.
