How to put Programme Committee Member on my resume

This might be seen as an academic question (pun intended), but at least for me it's part of daily life...

When someone organises an academic conference, they invite researchers to submit papers. The papers are reviewed by other researchers forming the so-called "programme committee" (PC), a process generally referred to as peer review.

Since it requires a good standing in the community it is often considered an (academic) honour to be part of the PC and at least younger researchers list all the PCs they have served on on their CVs.

Now my question is how to put a PC membership on my resume. Resumes are about accomplishments but it's tricky to say "contributed to conference XY by reviewing six papers (and refusing four of them)" since that is not really an accomplishment. In a way the accomplishment is to be nominated for the PC in the first place, but how do I put that on my resume?

Thanks for any insight,

Lars
