The holding company of U.S. insurer American International Group Inc’s AIG life and retirement business, SAFG Retirement Services Inc, filed for an initial public offering in the United States on Monday.

In the filing, SAFG reported total revenue of $23.4 billion for the year ended Dec. 31, up 55 percent. In the same period, adjusted after-tax operating income rose 14.5 percent to $2.9 billion.

Separately, AIG announced that BlackRock will manage some of its liquid fixed income and private placement assets.

BlackRock will manage up to $60 billion of the global AIG investment portfolio and up to $90 billion of the Life and Retirement investment portfolio.

Explaining the rebrand of AIG Life & Retirement in a media statement, Kevin Hogan, Executive Vice President and Chief Executive Officer of Life & Retirement, said: “Our team of committed colleagues work hard every day to find solutions that allow people to take action and build a secure bridge to their financial futures.

“As Corebridge, we will continue to proudly partner with financial and retirement professionals to help their clients feel confident and motivated today, and in control of their tomorrow.

The move sets the stage for what is expected to be one of the marquee listings this year, even as investor interest in IPOs has waned significantly due to recent stock market volatility amid fears of aggressive rate hikes from the U.S. Federal Reserve and the economic fallout of geopolitical tensions.

The filing comes less than a year after AIG announced plans to sell a 9.9 percent stake in the unit to private equity firm Blackstone Group Inc for $2.2 billion.

AIG first announced the decision to separate its life insurance and retirement businesses from its property/casualty operations in 2020, years after activist investors targeted the company for a break-up.

The insurer, which began to retool its underwriting in 2017 to make its core business more profitable said last year the process was largely complete and it was now pivoting to focus on growth.

AIG said on Monday following the IPO, it will continue to own more than 50 percent of SAFG.

The unit will be rebranded as Corebridge Financial Inc when it goes public.

J.P. Morgan, Morgan Stanley and Piper Sandler are the underwriters for the offering.
