Narrative:

We were set up for the visual backed up by the ILS DME to the runway. At approximately 2;000 ft after calling for flaps 25; I heard an aural warning. I was about to call for flaps when I noticed the 'te flaps asym' EICAS message. The handle was selected at 25 flaps but the flap gauge read 20 (both left and right). I brought the malfunction to the captain's attention. We decided to increase the reference speed to flaps 20; armed the auto brakes to 3 and touched down exiting off the runway at taxiway D. We did not declare an emergency. In hindsight; we could have; but I never felt that it warranted a 'mayday' call because I never felt that safety was compromised.
