Regulation
DTE Electric and DTE Gas are subject to the regulatory jurisdiction of the MPSC, which issues orders pertaining to rates, recovery of certain costs,
including the costs of generating facilities and regulatory assets, conditions of service, accounting and operating-related matters. DTE Electric is also regulated
by the FERC with respect to financing authorization and wholesale electric activities. Regulation results in differences in the application of generally accepted
accounting principles between regulated and non-regulated businesses.
The Company is unable to predict the outcome of the unresolved regulatory matters discussed herein. Resolution of these matters is dependent upon
future MPSC orders and appeals, which may materially impact the financial position, results of operations and cash flows of the Company.
Regulatory Assets and Liabilities
DTE Electric and DTE Gas are required to record regulatory assets and liabilities for certain transactions that would have been treated as revenue or
expense in non-regulated businesses. Continued applicability of regulatory accounting treatment requires that rates be designed to recover specific costs of
providing regulated services and be charged to and collected from customers. Future regulatory changes or changes in the competitive environment could result
in the discontinuance of this accounting treatment for regulatory assets and liabilities for some or all of our businesses and may require the write-off of the
portion of any regulatory asset or liability that was no longer probable of recovery through regulated rates. Management believes that currently available facts
support the continued use of regulatory assets and liabilities and that all regulatory assets and liabilities are recoverable or refundable in the current rate
environment.
The following are balances and a brief description of the regulatory assets and liabilities at December 31:
