GP catch-up

Also called Catch-up, Sponsor catch-up.

A general partner catch-up is a waterfall tier in which the general partner receives most or all of the distributions after the preferred return has been paid, until it has received its full promote percentage of all profit distributed so far. It restores the economic bargain the preferred return interrupted.

How it works

Without a catch-up, an 80/20 promote does not give the general partner 20 percent of profit. It gives 20 percent of whatever is left after the preferred return has been paid in full to the limited partners, which on a deal that only modestly clears its hurdle can be a small fraction of the intended amount. The catch-up tier fixes that by paying the general partner at an accelerated rate until the arithmetic is restored.

The rate is negotiable and is where most of the argument sits. A 100 percent catch-up sends every dollar to the general partner until it is caught up, which is fastest. A 50 percent catch-up splits the tier and takes twice as long, delaying and, on a deal that stops short, permanently reducing the promote. Both are common.

The catch-up amount itself is a simple algebraic consequence of the promote share and the pref that was paid. For a 20 percent promote, the catch-up equals 25 percent of the preferred return distributed, because at that point the general partner holds exactly one fifth of the total profit distributed. That relationship is a useful check on any waterfall model.

Formula

Full catch-up amount = preferred return paid x promote share / (1 - promote share)
  • At a 20 percent promote, the catch-up is 25 percent of the preferred return paid
  • At a 30 percent promote, it is roughly 42.9 percent of the preferred return paid
  • A partial catch-up rate, such as 50 percent, does not change the amount required, only how many dollars of distribution it takes to get there

Worked example

Checking a catch-up tier

Illustrative. Preferred return of $4,693,281 has been paid to the limited partners. Promote is 20 percent with a full 100 percent catch-up.

Catch-up required25% of the pref paid$1,173,320
Total profit distributed after the catch-up$5,866,601
General partner share of that20.0%
At a 50% catch-up rate, distributions needed to fill the tier$2,346,640
Same catch-up amount, twice the distributions to reach it$1,173,320

The catch-up amount is fixed by the promote percentage. The catch-up rate only determines how much total cash has to flow before the general partner has received it, which matters enormously on a deal that stops part way.

The common mistake

Modelling a catch-up on the wrong base

The catch-up is computed against profit distributions, meaning distributions above return of capital, not against total distributions including the returned capital. Running it against total distributions overstates the catch-up substantially, and on a deal where the limited partner capital is large relative to the profit it can hand the general partner more than its entire promote. The check is one line: after the catch-up tier is filled, the general partner should hold exactly the promote percentage of all profit distributed to date. If it does not, the base is wrong.
