KEY POINTS
  • Axa Equitable priced at $20 and began trading Thursday at the NYSE at $19.75.
  • The IPO raised $2.75 billion, making it the biggest U.S. IPO this year but it still fell short of Axa's targeted range.

Axa's $15.3 billion takeover of global property casualty firm XL Group was a monster deal in the insurance world, but Paris-based Axa's plan to pay for the acquisition has come up short.

The French company is selling its U.S. business, Axa Equitable Holdings, in an initial public offering. But the money it raised was about $1 billion less than the goal.
