Narrative:

Cleared to 12000 ft just prior to reaching assigned altitude, given changes to speed, heading, traffic and told to expect runway 16R. Distracted by all this and tuning radios for ILS, descended to approximately 11400 ft MSL. As we caught deviation, started to climb to 12000 ft and approach control then asked our assigned altitude. Asked approach controller if they needed any follow up. He checked with supervisor and said no further action needed.
