Mary Jo White and her husband have amassed assets of at least $16 million, according to a financial disclosure form filed by White, a partner at Debevoise & Plimpton who has been nominated to be the chair of the Securities and Exchange Commission. The form, which she filed last week with the U.S. Office of Government Ethics, also shows that White received slightly more than $2.4 million as a Debevoise partner last year.

The White family’s assets are likely significantly higher than $16 million, since the disclosure form only requires valuation of assets within a range of figures. For example, seven classes of their assets are valued from $1 milion to $5 million; an additional six assets are valued at more than $1 million. (This latter group of assets, owned solely by her husband, can be reported as worth more than $1 million, with no upper limit given.) The couple report no significant debt.
