The elevated interest in plan terminations may lead to more pension buy-in transactions, Mr. McDaniel said.
Pension buy-in transactions, in which a plan sponsor keeps the liabilities on their balance sheets but purchases an annuity contract to insure them, is common in the U.K. but has traditionally been very rare in the U.S.
"We're starting to see some innovation in that space, though, where plan sponsors enter into a buy-in contract at the start of that 18-month process with the intent of converting to a buyout at the end," Mr. McDaniel said.
"It locks in insurer capacity, so you don't get in 18 months from now and the market has tightened up for some reason. (It also provides) more certainty of pricing up front again, one of the challenges of the full plan termination."
According to LIMRA, there were four U.S. buy-in contracts totaling $2.7 billion in the first quarter of 2022, compared with one buy-in contract totaling $2.8 billion in all of 2021.
GSAM's Mr. Moran also noted that while plan terminations are on the uptick, some organizations are opting to simply chip away at their liabilities over time.
"They've done it multiple times now, so I think that's a theme that I call the 'return to market' theme," Mr. Moran said. "They may say 'We actually want to terminate the plan, but that's very expensive,' so for these organizations it's just about chipping away, coming back every year or two to chip off a little more and more."
Pittsburgh-based Alcoa Corp. is one such organization. The firm disclosed in an Aug. 8 news release it plans to close $1 billion in pension buyout transactions later this month.
The aluminum company purchased group annuity contracts from two Athene Holding subsidiaries to transfer about $1 billion in U.S. pension plan liabilities.
It is the third major pension buyout move by Alcoa in the past year. In December, Alcoa purchased group annuity contracts from Athene subsidiaries to transfer about $500 million in U.S. pension plan liabilities, representing about 2,600 participants.
In November, the company purchased contracts from the Athene subsidiaries to transfer about $1 billion in U.S. pension plan liabilities, representing about 11,200 retirees and beneficiaries.
In total, Alcoa has executed pension buyout deals to transfer $3.3 billion in U.S. and Canadian pension liabilities since April 2018.
As of Dec. 31, Alcoa's global pension plan assets totaled $4.3 billion, while projected benefit obligations totaled $4.59 billion, for a funding ratio of 93.7%, according to its latest 10-K filing.
By comparison, four years earlier, as of Dec. 31, 2017, Alcoa's global pension plan assets totaled $5.322 billion, while PBO totaled $7.639 billion, for a funding ratio of 69.7%, according to that year's 10-K filing.
Alcoa spokesman Jim W. Beck said in an email the company has made progress in strengthening its balance sheet in reducing pension liabilities and declined to comment further.
