commercial.key perms? 640 or 740?

[pgn]

i've installed & deployed a commercial SSL cert.

after deployment, zmfixperms, etc, the cert is recognized & verifies correctly.

checking on my system,

ls -al /opt/zimbra/ssl/zimbra/commercial/commercial.key
  -rw-r----- 1 root root 1679 Jun  8 11:14 /opt/zimbra/ssl/zimbra/commercial/commercial.key

yet, reading @, Administration Console and CLI Certificate Tools - Zimbra :: Wiki it states,

"The private key must exist in the /opt/zimbra/ssl/zimbra/commercial directory, and must be named commercial.key with its permission set to 740"

so what are the correct perms for 'commercial.key'?

640, as the deployment process & zmfixperms install?

or,

740, as the wiki states?

640, adding an execute bit (740) would be uselesss since the key is not executable. may want to file a bug report on the doucmentation.
