Yesterday was a big day for Big Law news.

Last night, K&L Gates and Australian law firm Middletons announced that their partners had approved their proposed merger. The combined firm will feature more than 2,000 lawyers in 46 offices worldwide and will retain the K&L Gates name. The deal, which will take effect Jan. 1, 2013, reflects an uptick in Australian mergers. In March, China's top law firm, King & Wood, merged with Australia's top firm, Mallesons Stephen Jaques. And in June, U.K.-based Herbert Smith merged with the Australian firm Freehills.

Kirkland & Ellis also was in the news yesterday. The firm topped the list of the American Lawyer's most valuable law firms. The publication valued Kirkland at $3.95 billion. Other top-valued firms include Latham & Watkins ($3.8 billion); Skadden, Arps, Slate, Meagher & Flom ($.3.34 billion); Allen & Overy ($2.71 billion); and Gibson Dunn & Crutcher ($2.71 billion).
