## Table 0 ##
Non-GAAP Measures Adjusted OIBDA Adjusted OIBDA is defined as operating income before depreciation, amortization, intangible impairments, (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net, Recall Costs (as defined below) and REIT Costs (as defined below).
Adjusted OIBDA Margin is calculated by dividing Adjusted OIBDA by total revenues.
We use multiples of current or projected Adjusted OIBDA in conjunction with our discounted cash flow models to determine our estimated overall enterprise valuation and to evaluate acquisition targets.
We believe Adjusted OIBDA and Adjusted OIBDA Margin provide our current and potential investors with relevant and useful information regarding our ability to generate cash flow to support business investment.
These measures are an integral part of the internal reporting system we use to assess and evaluate the operating performance of our business.
Adjusted OIBDA does not include certain items that we believe are not indicative of our core operating results, specifically: (1) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) gain on sale of real estate, net of tax; (3) intangible impairments; (4) Recall Costs (as defined below); (5) REIT Costs (as defined below); (6) other expense (income), net; (7) income (loss) from discontinued operations, net of tax; (8) gain (loss) on sale of discontinued operations, net of tax; and (9) net income (loss) attributable to noncontrolling interests.
Adjusted OIBDA also does not include interest expense, net and the provision (benefit) for income taxes.
These expenses are associated with our capitalization and tax structures, which we do not consider when evaluating the operating profitability of our core operations.
Finally, Adjusted OIBDA does not include depreciation and amortization expenses, in order to eliminate the impact of capital investments, which we evaluate by comparing capital expenditures to incremental revenue generated and as a percentage of total revenues.
Adjusted OIBDA and Adjusted OIBDA Margin should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States of America ("GAAP"), such as operating or net income (loss) or cash flows from operating activities from continuing operations (as determined in accordance with GAAP).
Reconciliation of Operating Income to Adjusted OIBDA (in thousands):
## Table 1 ##
(1) Includes operating expenditures associated with our proposed acquisition of Recall, including costs to complete the Recall Transaction, including advisory and professional fees, as well as costs incurred to integrate Recall with our existing operations, including moving, severance, facility upgrade, REIT conversion and system upgrade costs ("Recall Costs").
(2) Includes costs associated with our 2011 proxy contest, costs associated with our conversion to a REIT, excluding REIT compliance costs beginning January 1, 2014 which we expect to recur in future periods ("REIT Costs").
Adjusted EPS Adjusted EPS is defined as reported earnings per share from continuing operations excluding: (1) (gain) loss on disposal/ write-down of property, plant and equipment (excluding real estate), net; (2) gain on sale of real estate, net of tax; (3) intangible impairments; (4) Recall Costs; (5) REIT Costs; (6) other expense (income), net; and (7) the tax impact of reconciling items and discrete tax items.
We do not believe these excluded items to be indicative of our ongoing operating results, and they are not considered when we are forecasting our future results.
We believe Adjusted EPS is of value to our current and potential investors when comparing our results from past, present and future periods.
MORGAN STANLEY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The total amount of unrecognized tax benefits was approximately $2.2 billion, $4.1 billion, and $4.1 billion at December 31, 2014, December 31, 2013, and December 31, 2012, respectively.
Of this total, approximately $1.0 billion, $1.4 billion, and $1.6 billion, respectively (net of federal benefit of state issues, competent authority and foreign tax credit offsets) represent the amount of unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate in future periods.
Interest and penalties related to unrecognized tax benefits are classified as provision for income taxes.
The Company recognized $(35) million, $50 million, and $(10) million of interest expense (benefit) (net of federal and state income tax benefits) in the Company’s consolidated statements of income for 2014, 2013, and 2012, respectively.
Interest expense accrued at December 31, 2014, December 31, 2013, and December 31, 2012 was approximately $258 million, $293 million, and $243 million, respectively, net of federal and state income tax benefits.
Penalties related to unrecognized tax benefits for the years mentioned above were immaterial.
The following table presents a reconciliation of the beginning and ending amount of unrecognized tax benefits for 2014, 2013 and 2012 (dollars in millions):
## Table 2 ##
The Company is under continuous examination by the IRS and other tax authorities in certain countries, such as Japan and the U. K. , and in states in which the Company has significant business operations, such as New York.
