Catch-up
Also called GP catch-up, catch-up tier.
Catch-up is the tier of a distribution waterfall, paid after limited partners have received their capital and preferred return, in which the general partner receives all or most of the next proceeds until it has received its agreed percentage of total profit. After that, remaining proceeds are split at the carried interest rate.
Example
LPs contributed $50M and the fund returns $80M, a profit of $30M. The waterfall has an 8% preferred return, a 100% catch-up and 20% carry. The first $50M returns capital. The next $6M is the accrued preferred return, all to LPs. Then the catch-up: the GP takes every dollar until it holds 20% of profit distributed so far. That is $1.5M, because $1.5M is 20% of $7.5M ($6M plus $1.5M). The remaining $22.5M is split 80/20: $18M to LPs, $4.5M to the GP. The GP ends with $6M, exactly 20% of $30M.
Confused with
Hurdle rate. The hurdle is the threshold that must be cleared before the catch-up starts. The catch-up is what happens next.
Carried interest. Carry is the GP's share of profit. The catch-up is the tier that delivers it quickly once the hurdle is met, so that the hurdle ends up as a timing condition rather than a permanent discount.
In practice
Not every LPA has a full catch-up. A partial catch-up, say 80% to the GP and 20% to LPs during the tier, takes longer to reach the agreed split. No catch-up at all means the GP only ever shares in profit above the hurdle, which is a materially worse deal for the manager. The tier is where waterfall models most often go wrong, so administrators check it line by line against the LPA.
