(CBS) Well into his second career as owner of the Charlotte Bobcats, Michael Jordan has recorded his biggest earnings year yet.

Jordan made an estimated $90 million in 2013, due mostly to his partnership with Nike, according to a report by Forbes. It topped the $80 million he made in his last season with the Bulls, which was 1997-’98. Jordan’s earnings topped that of every other retired or current athlete with the exception of boxer Floyd Mayweather, Forbes reported.

From Forbes:

Retail shoe sales for the Jordan brand in the U.S. grew 11 percent last year to $2.7 billion, with basketball making up 84 percent of that … Roughly 50 percent to 55 percent of that goes to Nike. If you factor in sales of Jordan apparel, the international Jordan business and sales at Nike stores, the Jordan brand is contributing roughly $2 billion of revenue to Nike, which posted sales of $26 billion over the last 12 months. Jordan, the man, gets a cut of every shoe, hoodie or pair of shorts sold by Nike under the Jordan Brand. We estimate MJ’s take from Nike was at least $75 million last year.
