DTE Gas incurred CTA restructuring expense during a review of its operations which began in 2005. In September 2006, the MPSC issued an order
approving a settlement agreement that allowed DTE Electric and DTE Gas, commencing in 2006, to defer the incremental CTA. Further, the order provided
for DTE Electric and DTE Gas to amortize the CTA deferrals over a ten-year period beginning with the year subsequent to the year the CTA was deferred. The
September 2006 order did not provide a regulatory recovery mechanism for DTE Gas, therefore DTE Gas expensed CTA incurred during the period 2006
through 2008. A June 2010 MPSC order provided for DTE Gas’ recovery of the regulatory unamortized balance of CTA. DTE Gas deferred and recognized in
income approximately $32 million ($20 million after-tax) of previously expensed CTA in 2010.

Deferred tax assets and liabilities are recognized for the estimated future tax effect of temporary differences between the tax basis of assets or liabilities
and the reported amounts in the financial statements. Deferred tax assets and liabilities are classified as current or noncurrent according to the classification of
the related assets or liabilities. Deferred tax assets and liabilities not related to assets or liabilities are classified according to the expected reversal date of the
temporary differences. Consistent with rate making treatment, deferred taxes are offset in the table below for temporary differences which have related
regulatory assets and liabilities.
Deferred tax assets (liabilities) were comprised of the following at December 31:
