It's a valid cryptic clue. I don't think it's too difficult for normal people. It took me maybe half a minute, but variance here is really large; it depends on what you happen to think of in what order. (Also, I wasn't timing. It certainly wasn't as little as 15 seconds or as long as 2 minutes, but beyond that I wouldn't trust my judgement much.)
One thing I don't like very much (but it's a minor blemish if it's a blemish at all) is
cluing BOARDS by "company executives", for two nitpicky reasons. The first is that most of the people on a typical board aren't company executives. The second is that "boards" = "executives" feels like a bit of a type error: the things that make up "boards" are the boards, not the people on them. (A board is made up of people.)
For the second of those reasons, I think the clue would be slightly improved by making it

although that doesn't address my other quibble.
The surface reading is pretty good. The only thing I don't like about it is that it seems like it wants to be "executives'" rather than just "executives", but adding that apostrophe would be misleading in a way I'm not sure is quite fair. (Generally punctuation can be ignored, but apostrophes feel to me like they aren't just punctuation.) Ah, how about this?
