Ashton and Demi's $10 million divorce battle

After months of stalemate, the divorce between Ashton Kutcher and Demi Moore looked like it was finally going to move forward, until proceedings hit a snag this month over Kutcher's lucrative investment in a massive venture capital fund.

Kutcher, and his investment partners at their A-Grade investments fund, revealed earlier this month the fund was valued at about $100 million and was investing in tech start ups.

A-Grade was set up in 2010, when Kutcher and Moore were still married, but Kutcher reportedly told Moore's lawyers he had invested little in the fund, and that it hadn't made much money, a source told Page Six.

Kutcher and Oseary announced A-Grade's value at a Techcrunch conference early this month, a move the source said was "audacious and narcissistic."

“Now it seems Ashton and [A-Grade investor Guy] Oseary were working towards a private offering based on a valuation of $100 million. Ashton owns 20 percent of the fund, under California law, Demi should be entitled to half of his share -- $10 million.”

In the 19 months since the couple announced their split, they have failed to agree on a settlement.

"Ashton made a lot of money after they married, but he doesn't believe he owes her as much as she is asking for," the source said.
