For pricing the nuclear decommissioning trusts and other investments, a primary price source is identified by asset type, class, or issue for each security.  The trustee monitors prices supplied by pricing services and may use a supplemental price source or change the primary source of a given security if the trustee determines that another price source is considered preferable.  The Registrants have obtained an understanding of how these prices are derived, including the nature and observability of the inputs used in deriving such prices.Derivative Assets and LiabilitiesDerivative assets and liabilities are comprised of physical and financial derivative contracts, including futures, forwards, options, and swaps that are both exchange-traded and over-the-counter traded contracts.  Various inputs are used to value derivatives depending on the type of contract and availability of market data.  Exchange-traded derivative contracts are valued using quoted prices in active markets.  The Registrants consider the following criteria in determining whether a market is considered active: frequency in which pricing information is updated, variability in pricing between sources or over time, and the availability of public information.  Other derivative contracts are valued based upon a variety of inputs including commodity market prices, broker quotes, interest rates, credit ratings, default rates, market-based seasonality, and basis differential factors.  The Registrants monitor the prices that are supplied by brokers and pricing services and may use a supplemental price source or change the primary price source of an index if prices become unavailable or another price source is determined to be more representative of fair value.  The Registrants have obtained an understanding of how these prices are derived.  Additionally, the Registrants selectively corroborate the fair value of their transactions by comparison of market-based price sources.  Mathematical valuation models are used for derivatives for which external market data is not readily observable, such as contracts which extend beyond the actively traded reporting period.  The Registrants have established a Risk Management Committee whose responsibilities include directly or indirectly ensuring all valuation methods are applied in accordance with predefined policies.  The development and maintenance of the Registrants' forward price curves has been assigned to DTE Energy's Risk Management Department, which is separate and distinct from the trading functions within DTE Energy.The following tables present the fair value reconciliation of Level 3 assets
