Correction, 2/5/13, 5 p.m. EST: The original version of this article incorrectly stated that Munger, Tolles & Olson client HealthCare Partners acquired DaVita Inc. last year. DaVita was the acquiring company. The fourth paragraph of this article has been revised to incorporate the correct information. We regret the error.

Last year marked the 50th anniversary of Munger, Tolles & Olson’s founding—and the second straight year that the Los Angeles–based firm saw a double-digit increase in its profits per partner, according to The American Lawyer‘s reporting.
