Nearly two-thirds of U.S. companies that participated in a new litigation survey conducted by Houston’s Fulbright & Jaworski hired outside counsel to conduct an internal investigation.

Sixty-three percent of U.S. companies reported at least one in-house investigation within the 12 months prior to May or June, and 15 percent began three or more investigations during the same 12-month period. The percentage increases to 26 percent for U.S. companies with revenues in excess of $1 billion a year.
