After the merger with Northwest Airlines in 2008, Delta Air Lines had $7.3 billion in defined benefit pension assets and $15.93 billion in liabilities (45.8% funding ratio). Lower discount rates made things worse with the funding ratio falling to 38.1% in 2012.
Delta shows any plan sponsor the path forward: contributions. Contributions averaged $1 billion a year from 2010 to 2021, including a $3.5 billion contribution in 2017, which represented 24.15% of the plan’s starting assets in 2017. Delta noted the large contribution in its 10-K.
“In the first half of 2017, we contributed $3.5 billion to our qualified defined benefit pension plans using net proceeds from a $2.0 billion debt issuance, shares of our common stock from treasury with a value of $350 million and existing cash. As a result of these contributions, we satisfied, on an accelerated basis, our 2017 required contributions for our defined benefit plans, including more than $3.0 billion above the minimum funding requirements.”
Delta did not stop there, “We have no minimum funding requirements in 2018. However, in January 2018, we voluntarily contributed approximately $500 million to these plans.”
In addition to the contributions well in excess of legal requirements, excellent investment returns in the past three years have resulted in a funding ratio of 92.55% at the end of 2021.
