The sisters accused the brother, Ben Hill Griffin III, of stealing $4.4 million from the $300 million family trust, by inflating his salary as trustee and head of three family-owned companies.

Settlement terms were not filed with the court or disclosed publicly. But lawyers following the case and familiar with the Griffin family's properties tell GlobeSt.com the settlement will at least equal a similar arrangement the sisters won from their brother in 1998 after a similar battle.

In that settlement, according to court-filed documents, the sisters each won $4 million in cash; an additional $312,500 each in cash for lost dividends; and $5 million each in a 20-year bond earning 8% annual interest. The interest equates to $400,000 a year to each of the sisters.
