What is your university's policy on course reductions for service on dissertation committees? This is a question branching off of this one. I would like to judge how common it is for universities to give course reductions for service on dissertation committees.

Two questions:


Does your university offer such reductions for the advisor, readers, examiners?
How generous is the reduction? (1/3 of a course, 1/4 of a course, etc.)


Please include your discipline and location in the reply so we can get a more robust picture.

For instance: USA, Philosophy, 1/2 course for the dissertation advisor, 1/3 course for the readers, 0 for the examiners.
In mathematics in Minnesota, the advisor gets a half-course reduction, and committee members no reduction.

Thus, some years ago, when I taught a crypto class and a coding class that were popular with some engineering dept grad students, and I found myself being asked to be on about 250 Master's and PhD committees within a few years, it was a task that was not literally directly compensated-for, despite consuming significant time. But I figured it was part of my service duty. I allocated an hour or two prior to the actual presentation to review the document, and the presentation itself would take an hour or two.

(My chief benefit was amusement with some of my "colleagues" who apparently thought I was grossly exaggerating, since "obviously no one would agree to being on so many committees"...)
