    Quoted prices for similar assets and liabilities in active markets;
    
    Quoted prices for identical or similar assets or liabilities in inactive
    
    markets;
    
    Inputs other than quoted market prices that are observable for the asset or
liability; and
    
    Inputs that are derived principally from or corroborated by observable market data
