The following table shows annual aircraft fuel consumption and costs, including taxes, for our mainline and regional operations for 2018, 2017 and 2016 (gallons and aircraft fuel expense in millions).
## Table 0 ##
As of December 31, 2018, we did not have any fuel hedging contracts outstanding to hedge our fuel consumption.
As such, and assuming we do not enter into any future transactions to hedge our fuel consumption, we will continue to be fully exposed to fluctuations in fuel prices.
Our current policy is not to enter into transactions to hedge our fuel consumption, although we review that policy from time to time based on market conditions and other factors.
Fuel prices have fluctuated substantially over the past several years.
We cannot predict the future availability, price volatility or cost of aircraft fuel.
Natural disasters (including hurricanes or similar events in the U. S.  Southeast and on the Gulf Coast where a significant portion of domestic refining capacity is located), political disruptions or wars involving oil-producing countries, economic sanctions imposed against oil-producing countries or specific industry participants, changes in fuel-related governmental policy, the strength of the U. S.  dollar against foreign currencies, changes in the cost to transport or store petroleum products, changes in access to petroleum product pipelines and terminals, speculation in the energy futures markets, changes in aircraft fuel production capacity, environmental concerns and other unpredictable events may result in fuel supply shortages, distribution challenges, additional fuel price volatility and cost increases in the future.
See Part I, Item 1A.
Risk Factors – “Our business is very dependent on the price and availability of aircraft fuel.
Continued periods of high volatility in fuel costs, increased fuel prices or significant disruptions in the supply of aircraft fuel could have a significant negative impact on our operating results and liquidity.
” Seasonality and Other Factors Due to the greater demand for air travel during the summer months, revenues in the airline industry in the second and third quarters of the year tend to be greater than revenues in the first and fourth quarters of the year.
General economic conditions, fears of terrorism or war, fare initiatives, fluctuations in fuel prices, labor actions, weather, natural disasters, outbreaks of disease and other factors could impact this seasonal pattern.
Therefore, our quarterly results of operations are not necessarily indicative of operating results for the entire year, and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results.
Domestic and Global Regulatory Landscape General Airlines are subject to extensive domestic and international regulatory requirements.
Domestically, the DOT and the Federal Aviation Administration (FAA) exercise significant regulatory authority over air carriers.
The DOT, among other things, oversees domestic and international codeshare agreements, international route authorities, competition and consumer protection matters such as advertising, denied boarding compensation and baggage liability.
The Antitrust Division of the Department of Justice (DOJ), along with the DOT in certain instances, have jurisdiction over airline antitrust matters.
The following unaudited pro forma combined financial information does not purport to be indicative of actual results of BlackRock’s operations had the BGI Transaction actually been consummated at the beginning of each period presented.
Certain one-time charges that are directly attributable to the BGI Transaction have been eliminated.
The pro forma combined provision for income taxes may not represent the amount that would have resulted had BlackRock and BGI filed consolidated income tax returns during the years presented.
## Table 1 ##
(1) Subsequent to the closing of the BGI Transaction on December 1, 2009, BGI contributed $312 million of revenue, $141 million of operating income and $94 million of net income attributable to BlackRock, Inc.  (2) Includes the full year impact of the long-term notes issued in December 2009.
BlackRock and BGI costs included as pro forma adjustments (unaudited) For purposes of the pro forma financial information above, the following costs have been removed as they are deemed to be one-time costs directly attributable to the BGI Transaction.  ?
BlackRock results included $183 million of BlackRock pre-merger transaction and integration costs in conjunction with the BGI Transaction such as advisory fees, legal fees, consulting expenses recorded within general and administration expenses and compensation expense which have been expensed as incurred by BlackRock during the year ended December 31, 2009.  ?
BGI results for the eleven months ended November 30, 2009 included $299 million of costs related to acceleration of certain compensation costs that were triggered due to the transaction.
BGI costs and benefits not included as pro forma adjustments (unaudited) For purposes of the pro forma financial information above, the following items which are in BGI’s results and included in the pro forma results have not been removed as they are not directly attributable to the BGI Transaction: ?
A pre-tax expense of $2.285 billion for the year ended December 31, 2008 and a pre-tax benefit of $1.249 billion, for the eleven-month period ended November 30, 2009 related to capital support of certain BGI cash management products.
The liability related to such capital support has not been assumed in the transaction as it will remain with Barclays.  ?
BGI’s tax expense for the year ended December 31, 2008 and the eleven-month period ended November 30, 2009 included a non-recurring tax benefit of approximately $695 million and a tax expense of $381 million, respectively, related to the capital support.  ?
A pre-tax expense of $29 million for the eleven-month period ended November 30, 2009 related to a BGI restructuring independent from the sale to BlackRock.  ?
A pre-tax non-operating gain/(loss) of ($33) million and $1 million for the year ended December 31, 2008 and the eleven-month period ended November 30, 2009, respectively, related to valuation changes for certain investments that were not acquired by BlackRock.
If such costs and benefits were excluded the pro forma diluted EPS for 2009 would have decreased by $4.37 and for 2008 would have increased by $8.33.
Impact Investing In August 2008, the Company acquired Impact Investing, an Australia based software development company specializing in equity portfolio management and analytical software tools.
The maximum remaining and total consideration to be paid is not expected to be material to the Company’s consolidated financial statements.
Quellos Group On October 1, 2007, the Company closed the Quellos Transaction and paid Quellos $562.5 million in cash and issued 1,191,785 shares of BlackRock common stock, valued at $188 million.
The common stock was placed in escrow for up to three years and is available to satisfy certain indemnification obligations of Quellos under the asset purchase agreement.
The value of the common stock consideration was determined using the average closing price of BlackRock’s common stock ten days before the Quellos Transaction announcement date.
In addition, Quellos may receive two contingent payments, upon achieving certain investment advisory base and performance fee measures through December 31, 2010, totaling up to $969 million in a combination of cash and stock.
During 2009, the Company determined the first contingent payment to be $219 million, of which $11 million was previously paid in cash during 2008.
Of the remaining $208 million, $156 million was paid in cash and $52 million was paid in common stock, or approximately 330,000 shares based on a price of $157.33 per share.
The second contingent payment, of up to $595 million, is based on investment advisory fees through 2010 and is payable in cash in 2011.
Quellos may also be entitled to a “catch-up” payment in 2011 if certain investment advisory base fee measures are met through 2010 to the extent that the value of the first contingent payment is less than $374 million.
The Quellos Transaction was accounted for under the purchase method of accounting in accordance with ASC 805 prior to the changes within ASC 805 which were adopted on January 1, 2009.
Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values at the date of the transaction.
The excess, if any, of the final
Deferred income taxes are provided for the effects of temporary differences between the tax basis of an asset or liability and its reported amount in the Company’s consolidated financial statements.
These temporary differences result in taxable or deductible amounts in future years.
The components of deferred income tax assets and liabilities are shown below:
## Table 2 ##
Deferred income tax assets and liabilities are recorded net when related to the same tax jurisdiction.
At December 31, 2011, the Company recorded on the consolidated statement of financial condition deferred income tax assets, within other assets, and deferred income tax liabilities of $6 million and $5,323 million, respectively.
At December 31, 2010, the Company recorded on the consolidated statement of financial condition deferred income tax assets, within other assets, and deferred income tax liabilities of $10 million and $5,477 million, respectively.
In the second and third quarter of 2011, an enacted state tax law and a state tax election went into effect, which resulted in a revaluation of certain net deferred income tax liabilities primarily related to acquired intangible assets, which resulted in a $52 million and $91 million tax benefit, respectively.
The United Kingdom in the third quarter of 2011, and Japan in the fourth quarter of 2011, enacted legislation reducing corporate income tax rates, which resulted in a revaluation of certain net deferred income tax liabilities primarily related to acquired intangible assets, which resulted in a $60 million and $13 million tax benefit, respectively.
The Company had a deferred income tax asset related to unrealized investment losses of approximately $110 million and $108 million as of December 31, 2011 and 2010, respectively, reflecting the Company’s conclusion that, based on the weight of available evidence, it is more likely than not that the deferred tax asset will be realized.
Realized capital losses may be carried back three years and carried forward five years and offset against realized capital gains for federal income tax purposes.
The Company expects to be able to carry back a portion of its unrealized capital losses when realized, hold certain fixed income securities over a period sufficient for them to recover their unrealized losses, and to generate future capital gains sufficient to offset the unrealized capital losses.
At December 31, 2011 and 2010, the Company had available state net operating loss carry forwards of $388 million and $182 million, respectively, which will expire on or before 2032.
As of December 31, 2011, the Company had foreign net operating loss carryforwards of $132 million of which $45 million expires on or before 2021 and the balance will carry forward indefinitely.
In addition, at December 31, 2011 and 2010, the Company had U. S.  capital loss carryforwards of $90 million, which were acquired in the BGI Transaction and will expire on or before 2013.
At December 31, 2011 and 2010, the Company had $95 million and $78 million of valuation allowances for deferred income tax assets, respectively, recorded on the consolidated statements of financial condition.
The year-over-year increase in the valuation allowance primarily related to certain foreign deferred income tax assets.
Goodwill recorded in connection with the Quellos Transaction has been reduced during the period by the amount of tax benefit realized from tax-deductible goodwill.
See Note 9, Goodwill, for further discussion.
Current income taxes are recorded net in the consolidated statements of financial condition when related to the same tax jurisdiction.
As of December 31, 2011, the Company had current income taxes receivable and payable of $108 million and $102 million, respectively, recorded in other assets and accounts payable and accrued liabilities, respectively.
As of December 31, 2010, the Company had current income taxes receivable and payable of $57 million and $157 million, respectively, recorded in other assets and accounts payable and accrued liabilities, respectively.
The Company does not provide deferred taxes on the excess of the financial reporting over tax basis on its investments in foreign subsidiaries that are essentially permanent in duration.
The excess totaled $1,516 million and $1,297 million as of December 31, 2011 and 2010, respectively.
The determination of the additional deferred income taxes on the excess has not been provided because it is not practicable due to the complexities associated with its hypothetical calculation.
The following table presents the component changes in BlackRock’s AUM for 2017, 2016 and 2015.
## Table 3 ##
(1) Advisory AUM represents long-term portfolio liquidation assignments.
(2) Amount for 2017 represents $3.3 billion of AUM acquired in the First Reserve Infrastructure business transaction in June 2017 (“First Reserve Transaction”).
Amount for 2016 represents $80.6 billion of AUM acquired in the BofA Global Capital Management transaction in April 2016.
Amounts for 2015 represent $1.3 billion of AUM acquired in the acquisition of certain assets of BKCA in March 2015, $560 million of AUM acquired in the Infraestructura Institucional acquisition in October 2015 and $366 million of AUM acquired in the FutureAdvisor acquisition in October 2015.
The FutureAdvisor acquisition amount does not include AUM that was held in iShares holdings.
(3) Foreign exchange reflects the impact of translating non-U.
S.  dollar denominated AUM into U. S.  dollars for reporting purposes.
BlackRock has historically grown AUM through organic growth and acquisitions.
Management believes that the Company will be able to continue to grow AUM organically by focusing on strong investment performance, efficient delivery of beta for index products, client service, developing new products and optimizing distribution capabilities.
Component Changes in AUM for 2017 The following table presents the component changes in AUM by client type and product type for 2017.
## Table 4 ##
(1) Amount represents AUM acquired in the First Reserve Transaction.
(2) Foreign exchange reflects the impact of translating non-U.
S.  dollar denominated AUM into U. S.  dollars for reporting purposes.
(3) Average AUM is calculated as the average of the month-end spot AUM amounts for the trailing thirteen months.
(4) Advisory AUM represents long-term portfolio liquidation assignments.
