| • | Level 1 Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access. | 
| • | Level 2 Inputs to the valuation methodology include:  quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; inputs other than quoted prices
                  that are observable for the asset or liability; inputs that are derived principally from or corroborated by observable market data by correlation or other means.  If the asset or liability has a specified (contractual) term, the Level 2
                  input must be observable for substantially the full term of the asset or liability. | 
| • | Level 3 Inputs to the valuation methodology are unobservable and significant to the fair value measurement. |
