$ ls -l ar.exp
-rw-rw-rw- 1 root system 2150739 May 12 23:22 ar.exp

Note the 't' bit on the directory. From the manpage (FreeBSD) :
1000 (the sticky bit) When set on a directory, unprivileged
users can delete and rename only those files in the direc_
tory that are owned by them, regardless of the permissions
on the directory. Under FreeBSD, the sticky bit is ignored
for executable files and may only be set for directories
(see sticky(8)).
AIX is strange, but in this respect unix-compatible.

The directory's sticky bit is set. Only the owner of a file or the
owner of the directory may remove or rename the file.
