Kodak stock jumped Tuesday after it found a lot of cash—in the company’s pension plan. Monday, Kodak said its pension plan sold “illiquid” assets worth about $764 million for about $551 million. It’s selling some other assets listed at $87 million for $62 million.

Eastman Kodak Co. is making changes to its pension plan, including selling some of its assets and possibly terminating the plan.

Eastman Kodak has begun taking steps to end its $3.5 billion pension plan, agreeing to sell private-equity and other illiquid assets attached to it.

Kodak stands to gain more than a half-billion dollars if the current pension plan is terminated, due to a surplus in the fund. Company officials said the changes would also 'preserve and protect' the retirement benefits of current participants in the plan.

Kodak could benefit from a whopping $585m (£464m) windfall – more than the current value of the entire company – if plans to sell off its pension fund come to fruition.

The board of Eastman Kodak’s pension plan sold a portfolio of illiquid assets to the Mastercard Foundation and is considering winding down the rest of the fund, as the company looks to tap the roughly $1 billion surplus it built up over the years.
