"In this marital dissolution action, appellant Thomas Williams and respondent Hilary Williams dispute the amount of child support that Thomas should pay for their two children. Both parties are wealthy and unemployed. . . . The trial court ruled that Thomas’s earning capacity should include attribution of a reasonable return on approximately $14 million in investments (including home equity of $6 million in his Pebble Beach estate) . . . . In 1995, Thomas sold his company, Combinet, to Cisco Systems, Inc. and received Cisco shares valued between $65 million and $85 million.
