Table of Contents ADOBE SYSTEMS INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) Deferred Tax Assets and Liabilities The tax effects of the temporary differences that gave rise to significant portions of the deferred tax assets and liabilities as of December 2, 2011 and December 3, 2010 are presented below (in thousands):
## Table 0 ##
The deferred tax assets and liabilities for fiscal 2011 and fiscal 2010 include amounts related to various acquisitions.
The total change in deferred tax assets and liabilities in fiscal 2011 includes changes that are recorded to OCI, additional paid-in capital, goodwill and retained earnings.
During fiscal 2010, we repatriated $700 million of undistributed foreign earnings for which a deferred tax liability had been previously recognized.
As such, a long-term deferred tax liability of approximately $200 million was reclassified from deferred income taxes to income taxes payable in the first quarter of fiscal 2010 and was paid during fiscal 2010.
We provide U. S.  income taxes on the earnings of foreign subsidiaries unless the subsidiaries’ earnings are considered permanently reinvested outside the U. S.  To the extent that the foreign earnings previously treated as permanently reinvested are repatriated, the related U. S.  tax liability may be reduced by any foreign income taxes paid on these earnings.
As of December 2, 2011, the cumulative amount of earnings upon which U. S.  income taxes have not been provided is approximately $2.4 billion.
The unrecognized deferred tax liability for these earnings is approximately $0.7 billion.
As of December 2, 2011, we have U. S.  net operating loss carryforwards of approximately $32.4 million for federal and $37.5 million for state.
We also have federal and state tax credit carryforwards of approximately $9.4 million and $23.7 million, respectively.
The net operating loss carryforward assets, federal tax credits and foreign tax credits will expire in various years from fiscal 2017 through 2031.
The state tax credit carryforwards can be carried forward indefinitely.
The net operating loss carryforward assets and certain credits are subject to an annual limitation under Internal Revenue Code Section 382, but are expected to be fully realized.
In addition, we have been tracking certain deferred tax attributes of $44.6 million which have not been recorded in the financial statements pursuant to accounting standards related to stock-based compensation.
These amounts are no longer included in our gross or net deferred tax assets.
Pursuant to these standards, the benefit of these deferred tax assets will be recorded to equity when they reduce taxes payable.
THE AES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) DECEMBER 31, 2011, 2010, AND 2009 The preliminary allocation of the purchase price to the fair value of assets acquired and liabilities assumed is as follows (in millions):
## Table 1 ##
At December 31, 2011, the assets acquired and liabilities assumed in the acquisition were recorded at provisional amounts based on the preliminary purchase price allocation.
The Company is in the process of obtaining additional information to identify and measure all assets acquired and liabilities assumed in the acquisition within the measurement period, which could be up to one year from the date of acquisition.
Such provisional amounts will be retrospectively adjusted to reflect any new information about facts and circumstances that existed at the acquisition date that, if known, would have affected the measurement of these amounts.
Additionally, key input assumptions and their sensitivity to the valuation of assets acquired and liabilities assumed are currently being reviewed by management.
It is likely that the value of the generation business related property, plant and equipment, the intangible asset related to the Electric Security Plan with its regulated customers and long-term coal contracts, the 4.9% equity ownership interest in the Ohio Valley Electric Corporation, and deferred taxes could change as the valuation process is finalized.
DPLER, DPL’s wholly-owned Competitive Retail Electric Service (“CRES”) provider, will also likely have changes in its initial purchase price allocation for the valuation of its intangible assets for the trade name, and customer relationships and contracts.
As noted in the table above, the preliminary purchase price allocation has resulted in the recognition of $ 2.5 billion of goodwill.
Factors primarily contributing to a price in excess of the fair value of the net tangible and intangible assets include, but are not limited to: the ability to expand the U. S.  utility platform in the Mid-West market, the ability to capitalize on utility management experience gained from IPL, enhanced ability to negotiate with suppliers of fuel and energy, the ability to capture value associated with AES’ U. S.  tax position, a wellpositioned generating fleet, the ability of DPL to leverage its assembled workforce to take advantage of growth opportunities, etc.
Our ability to realize the benefit of DPL’s goodwill depends on the realization of expected benefits resulting from a successful integration of DPL into AES’ existing operations and our ability to respond to the changes in the Ohio utility market.
For example, utilities in Ohio continue to face downward pressure on operating margins due to the evolving regulatory environment, which is moving towards a market-based competitive pricing mechanism.
At the same time, the declining energy prices are also reducing operating
