Hellman & Friedman poised to buy DoubleClick

"San Francisco's Hellman & Friedman LLC could be close to acquiring the Internet-advertising firm DoubleClick Inc., according to a report published earlier this week."

"DoubleClick's shares climbed 16 percent Thursday to $8.56 after the New York Post identified buyout shop Hellman & Friedman as the leading contender to purchase the New York firm in a deal with an estimated value of $1.2 billion. The shares were little changed Friday. Both firms declined to comment."
