Plan assets using fair value hierarchy
The following tables present plan assets using the fair value hierarchy as of December 31, 2012 and 2011.  The fair value hierarchy has three levels based on the reliability of inputs used to determine fair value.  Level 1 refers to fair values determined based on quoted prices in active markets for identical assets.  Level 2 refers to fair values estimated using observable prices that are based on inputs not quoted in active markets but observable by market data, while Level 3 includes the fair values estimated using significant non-observable inputs.  The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
