Some familiar names graced the largest deal announcements this week, with Skadden, Arps, Slate, Meagher & Flom, Kirkland & Ellis, Wachtell, Lipton, Rosen & Katz and Simpson Thacher & Bartlett among the law firms that were involved in an impressive list of pair-ups.

In total, 13 deals with a value of over $1 billion were reported, four were over $7 billion and two north of $10 billion—the generally accepted value for a “megadeal.”
