Nicola Hanna, the former Gibson, Dunn & Crutcher white-collar partner who's now leading the U.S. Attorney's Office in Los Angeles, reported a $3.7 million partnership share, according to documents the U.S. Office of Government Ethics posted this week.

Hanna, a Gibson Dunn partner since 1998, identified his anticipated partnership share—which he would receive by January 2019—at between $1 million and $5 million.

U.S. attorney nominees and other executive agency picks are required to file publicly reviewable financial disclosures, documents that offer a window to compensation schemes at some of the country's largest law firms. Hanna's reported $3.76 million partnership share would have included 2017 and 2016, according to the rules for disclosing income amounts.
