Why is the "ls" command showing permissions of files in a FAT32 partition?

I believe that the FAT32 file system does not support file permissions, however when I do ls -l on a FAT32 partition, ls -l shows that the files have permissions: -rw-r--r-- 1 john john 11 Mar 20 15:43 file1.txt -rw-r--r-- 1 john john 5 Mar 20 15:49 file2.txt Why is ls -l displaying the permissions of files?
