Westin’s chairman is involved in buyout talks.

Chairman Harry Mullikin said the possible management-led buyout deal could include the Hilton International hotel chain, which parent company Allegis Corp. bought for $982.5 million in March. Hilton operates 90 hotels, and Westin runs 62 in 48 cities. Together they employ 72,000 people. Westin had a profit of $75.2 million on sales of just over $1 billion in 1986. Hilton International had sales in the $1.3-billion range, said Mullikin, who estimated that talks would take at least three months. Industry analysts say Westin could be worth anywhere from $500 million to $1.2 billion.
