The New York Times reported early Friday that two corporate partners at Skadden, Arps, Slate, Meagher & Flom — David Fox and Daniel Wolf — are leaving the firm for Kirkland & Ellis.

Fox, 51, an M&A lawyer and reportedly one of the firm’s most highly compensated partners, joined the firm more than 20 years ago. Wolf, also an M&A partner, is one of the youngest lawyers to have made partner at Skadden — he was promoted six years ago at the age of 30. Both lawyers have worked together on several matters in recent years, including BHP Billiton’s $150 billion bid for Rio Tinto.
