Lightweight metals leader Alcoa (NYSE:AA) today reported full-year 2015
results, ending the year on solid operational footing. In fourth quarter
2015, the Value-Add businesses reported strong performance, while the
Upstream remained profitable despite lower alumina and aluminum prices.
Every segment delivered productivity gains. The Company also
undertook restructuring to further strengthen the Upstream portfolio and
streamline overhead ahead of its planned separation in the second half
of 2016.

In fourth quarter 2015, Alcoa reported a net loss of $500 million, or
$0.39 per share. Results include $565 million in special items related
primarily to closures or curtailments of capacity in the Upstream
business and discrete income tax charges. Fourth quarter 2015 results
compare to net income of $159 million, or $0.11 per share, in fourth
quarter 2014.

Excluding special items, fourth quarter 2015 net income was $65 million,
or $0.04 per share, compared to net income of $432 million, or $0.33 per
share, in the year-ago period. Strong productivity gains were more than
offset by lower alumina and aluminum prices. In 2015, the Midwest
transaction price for primary aluminum fell $657 per metric ton, or 28
percent, and the Alumina Price Index dropped $154 per metric ton, or 43
percent.

Fourth quarter 2015 revenue was $5.2 billion, down 18 percent from $6.4
billion in fourth quarter 2014. Organic growth in aerospace and
acquisitions increased revenue 7 percent, which was more than offset by
a 25 percent revenue decline from lower alumina and aluminum prices, the
impact of divested, curtailed or closed facilities, and unfavorable
currency.

“2015 was a pivotal year for Alcoa,” said Klaus Kleinfeld, Alcoa
Chairman and Chief Executive Officer. “We substantially strengthened our
aerospace offerings through innovations and acquisitions and our
customers responded favorably, awarding us $9 billion in aerospace
contracts; and we continued to ramp up our automotive business and shift
the midstream to a higher-margin product mix. In the Upstream, we faced
harsh headwinds with prices for alumina down 43 percent and aluminum
down 28 percent. As a result of our closures, curtailments, productivity
actions and new business structure we improved competitiveness and
strengthened the portfolio. We are fully on track to launch two strong,
standalone companies in the second half of 2016.”

Turning to the current quarter, Kleinfeld continued, “Our solid fourth
quarter results reflect our active portfolio management. Aerospace
momentum accelerated with record sales and a $4 billion string of major
contract wins. In the midstream, adjusted EBITDA per metric ton grew 19
percent as our shift to higher value products like automotive paid off.
A new $650 million Value-Add business improvement program will further
sharpen our profitability edge. In the Upstream, alumina prices dropped
a further 24 percent and aluminum prices stayed stubbornly low. We took
aggressive actions: closed and curtailed more unprofitable capacity,
accelerated productivity and weathered the storm with Upstream remaining
profitable. To further boost resilience we launched a $600 million
Upstream business improvement program. We ended the year in an excellent
cash position, with all businesses delivering strong productivity.”

2015 Full-Year Results

In 2015, Alcoa reported a net loss of $121 million, or $0.15 per share,
compared to net income of $268 million, or $0.21 per share, in 2014.
Excluding the impact of special items, the Company reported net income
of $787 million, or $0.56 per share, in 2015, down from $1.1 billion, or
$0.92 per share, in 2014. Strong productivity and favorable currency
impacts were more than offset by lower metal prices and cost increases.
Revenue in 2015 was $22.5 billion, down 6 percent from $23.9 billion in
2014.

In 2015, Alcoa delivered strong performance against its financial
targets. The Company achieved $1.2 billion in productivity savings,
exceeding a $900 million annual target; managed return-seeking capital
of $602 million against a $750 million annual target; controlled
sustaining capital expenditures of $605 million against a $725 million
annual target; and attained a debt-to-adjusted EBITDA ratio of 2.80,
slightly above the target range.

For full-year 2015, Alcoa’s cash from operations totaled $1.6 billion,
resulting in $402 million in positive free cash flow. In fourth quarter
2015, the Company’s cash from operations was $865 million, which drove
$467 million in positive free cash flow. Alcoa’s debt totaled $9.1
billion at the end of 2015, with cash on hand of $1.9 billion, resulting
in net debt of $7.2 billion.

Separation Update

Alcoa’s plan to separate into two publicly traded companies is expected
to be completed in the second half of 2016. Alcoa has announced
executive management teams for the future Value-Add and Upstream
companies, both of which will be U.S. domiciled.

Alcoa is also undertaking business improvement programs across its
portfolios: Value-Add will deliver $650 million and the Upstream $600
million, both in productivity and margin improvement, in 2016. This
includes implementation of an overhead reduction program across the
Company, of which $100 million in benefits will be realized in 2016, and
$225 million over two years.

Alcoa is targeting a Form 10 filing with the U.S. Securities and
Exchange Commission by mid-year, which will include financials and
information regarding the form of the separation, legal and capital
structure and allocation of assets and liabilities and governance
structure, among other items. The separation will be completed subject
to the Form 10 being declared effective, final approval from Alcoa’s
Board of Directors and completed financing.

Value-Add Business Highlights

After the separation, the innovation and technology-driven Value-Add
Company will include Global Rolled Products, Engineered Products and
Solutions and Transportation and Construction Solutions.

For full-year 2015, these combined business segments reported revenue of
$13.5 billion, after-tax operating income (ATOI) of $1.0 billion and
adjusted EBITDA of $2.0 billion, up 5 percent over 2014. Other full-year
highlights:

• Global Rolled Products realized a year-over-year, 15 percent increase
  in adjusted EBITDA per metric ton, reflecting a shift to a
  higher-margin product mix; automotive sheet shipments doubled from
  2014.
• Engineered Products and Solutions revenue up 27 percent and adjusted
  EBITDA up 9 percent from 2014.

Alcoa secured approximately $9 billion in aerospace contracts in 2015,
more than double the amount in 2014, as recent aerospace growth
investments delivered value. In the fourth quarter, the Company
announced long-term
agreements with Boeing valued at over $2.5 billion. Alcoa will
supply fastening systems for every Boeing platform and ready-to-install
titanium seat track assemblies for the entire 787 Dreamliner family. The
seat tracks, from raw material to finished part, will be made using
titanium capabilities Alcoa gained through the RTI acquisition. Earlier
today, the Company also announced a more than $1.5
billion contract with GE Aviation. Alcoa will provide advanced
nickel-based superalloy, titanium and aluminum jet engine components for
a broad range of GE Aviation engine programs.

The Company opened its state-of-the-art jet engine parts facility in La
Porte, Indiana in the fourth quarter. The facility enables Alcoa to
manufacture nickel-based structural parts that are nearly 60 percent
larger for the industry’s best-selling jet engines for large commercial
aircraft. In addition, Alcoa completed its jet engine expansion in
Hampton, Virginia. This facility includes technology that cuts the
weight of Alcoa’s highest-volume jet engine blades by 20 percent and
significantly improves aerodynamic performance.

In the automotive business, Alcoa’s shipments of aluminum automotive
sheet grew 18 percent and, by shifting the revenue mix to higher-margin
products, EBITDA per metric ton increased 19 percent, both
year-over-year. The Company’s newly expanded Alcoa, Tennessee facility
continued to ramp up automotive sheet shipments in the fourth quarter.
The plant will provide aluminum sheet to automakers that include Ford,
Fiat Chrysler Automobiles and General Motors.

Upstream Business Highlights

After the separation, the Upstream Company will comprise five strong
business units that today make up Global Primary Products: Bauxite,
Alumina, Aluminum, Cast Products and Energy. In full-year 2015, the
combined Upstream businesses reported revenue of $11.2 billion, ATOI of
$901 million and adjusted EBITDA of $2.0 billion.

In the fourth quarter, Alcoa made significant progress executing its
plan to strengthen its Upstream portfolio. As a result, the Company is
on target to meet or exceed its 2016 goals of moving to the 38^th
percentile on the global aluminum cost curve and 21^st
percentile on the global alumina cost curve. During the fourth quarter,
the Company:

• Entered into a three-and-a-half year agreement with New York State to
  increase the competitiveness of its Massena West smelter, improving
  its cost position and supporting growth projects for the casthouse;
• Announced plans to curtail smelting capacity at the Intalco and
  Wenatchee primary aluminum smelters in Washington State by the end of
  the first quarter 2016 and permanently close the Massena East, New
  York site; and
• Curtailed the remaining capacity at its Suralco refinery in Suriname,
  as previously announced, and announced that it will curtail refining
  capacity at its Point Comfort, Texas refinery.

Earlier this month, Alcoa also said it will:

• Permanently close the Warrick Operations smelter in Evansville,
  Indiana; and
• Reduce additional alumina production by one million metric tons across
  its refining system, including curtailing the remaining capacity at
  its Point Comfort refinery.

Alcoa’s aggressive portfolio actions will remove approximately 25
percent operating smelting capacity and approximately 20 percent of
operating refining capacity by mid-2016. Once all of the above actions
are implemented, Alcoa globally will have 2.1 million metric tons of
operating smelting capacity and 12.3 million metric tons of operating
refining capacity remaining.

2016 End Market Projections

Alcoa projects another strong year for global aerospace sales. The
Company expects 2016 global aerospace sales to increase 8 to 9 percent
over 2015 on continued robust demand for large commercial aircraft and
jet engines. In automotive, the Company forecasts global production
growth of 1 to 4 percent, including 1 to 5 percent growth in North
America driven by strong sales.

In the heavy duty truck and trailer market, Alcoa projects production of
negative 3 to positive 1 percent globally. In North America, the heavy
duty truck and trailer market is expected to decline 19 to 23 percent
this year after a strong end for 2015, which was the fourth highest
production year on record. In the packaging market, Alcoa forecasts
global sales growth of 1 to 3 percent in 2016.

Alcoa expects the building and construction market to continue to
improve in 2016, with global sales growth of 4 to 6 percent with the
same growth range in North America.

In the industrial gas turbine market, the Company projects a 2 to 4
percent growth rate in 2016. The airfoil market continues to improve as
original equipment manufacturers move to higher value-add products for
new high efficiency turbines with advanced technology.

In 2016, Alcoa expects a global aluminum deficit of 1.2 million metric
tons and a global alumina deficit of 2.8 million metric tons due to
global curtailments. The Company also projects record global aluminum
demand in 2016 of 60.5 million metric tons, up 6 percent over 2015.
Global aluminum demand is expected to double between 2010 and 2020; so
far this decade, global demand growth is tracking ahead of this
projection.

Segment Information

Global Rolled Products

ATOI in the fourth quarter was $52 million, flat as compared to the
year-ago quarter. Strong productivity and automotive shipment growth of
18 percent were offset by cost increases, volume declines in aerospace
from fewer spot opportunities and packaging, portfolio actions, and
investments for ramping up growth projects, including the Tennessee
automotive expansion and Micromill commercialization. As a result of
this segment’s ongoing transformation initiatives, including
divestitures and upgrading the product mix, adjusted EBITDA per metric
ton was $312 in fourth quarter 2015, up 19 percent, or $50, from $262 in
the year-ago quarter.

Engineered Products and Solutions

In the fourth quarter, this segment reported record revenue of $1.41
billion, up 26 percent year-over-year; a 34 percent increase in
aerospace sales; and ATOI of $123 million, essentially flat
year-over-year from $124 million. The RTI acquisition contributed $7
million of ATOI to the quarter, which is net of $6 million of an
unfavorable impact attributable to purchase accounting adjustments.
Year-over-year, productivity improvements of $54 million and positive
contributions from the Firth Rixson and RTI acquisitions were largely
offset by cost headwinds, investments in growth projects and unfavorable
price/mix. Compared to 2014, 2015 revenue was $5.3 billion, up 27
percent, ATOI was $595 million, up 3 percent, and adjusted EBITDA was
$1.1 billion, up 9 percent.

Transportation and Construction Solutions

ATOI was $40 million in the fourth quarter, up $2 million, or 5 percent,
year over year. The increase was mostly driven by productivity gains,
partially offset by cost headwinds. This segment delivered a fourth
quarter record adjusted EBITDA margin of 14.6 percent, compared to 12.6
percent in the year-ago quarter.

Alumina

In the face of a 24 percent alumina price decline, ATOI was $98 million
in the fourth quarter, down $114 million sequentially from $212 million
and $80 million lower year-over-year from $178 million. Sequentially,
cost reductions slightly offset the impact of lower pricing related to
both the Alumina Price Index and London Metal Exchange-based contracts
and unfavorable foreign currency movements. Adjusted EBITDA per metric
ton decreased $38 from third quarter 2015 to $57 in fourth quarter 2015
and decreased $28 year-over-year.

Primary Metals

ATOI in the fourth quarter was a negative $40 million, a $19 million
sequential improvement from a negative $59 million, and down $307
million year-over-year from $267 million. Sequentially, ATOI improved
due to lower costs for alumina and energy and higher energy sales,
partially offset by a lower average realized aluminum price, resulting
from both lower London Metal Exchange aluminum pricing and regional
premiums. Despite third-party realized pricing declining 5 percent in
fourth quarter 2015 to $1,799 per metric ton, cost improvements drove a
$26 increase in adjusted EBITDA per metric ton to $30.

Alcoa will hold its quarterly conference call at 5:00 PM Eastern Time
on January 11, 2016 to present quarterly results. The meeting will be
webcast via alcoa.com. Call information and related details are
available at www.alcoa.com
under “Invest.” Presentation materials will be available for viewing

(1)		In order to calculate both basic and diluted earnings per share for the years ended December 31, 2014 and 2015, preferred stock dividends declared of $21 and $69, respectively, need to be subtracted from Net income (loss) attributable to Alcoa.
(2)		In the first quarter of 2014, holders of $575 principal amount of Alcoa’s 5.25% Convertible Notes due March 15, 2014 (the “Notes”) exercised their option to convert the Notes into 89 million shares of Alcoa common stock. As a result, the basic average number of shares for the year ended December 31, 2014 includes 73 million representing the weighted average number of shares for the length of time the 89 million shares were outstanding during 2014, and the basic average number of shares for the year ended December 31, 2015 includes all 89 million shares.
		Additionally, in the fourth quarter of 2014, Alcoa issued 37 million shares of its common stock as part of the consideration paid to acquire Firth Rixson. As a result, the basic average number of shares for the year ended December 31, 2014 includes 4 million representing the weighted average number of shares for the length of time the 37 million shares were outstanding during 2014, and the basic average number of shares for the year ended December 31, 2015 includes all 37 million shares.
		Furthermore, in the third quarter of 2015, Alcoa issued 87 million shares of its common stock to acquire RTI International Metals. As a result, the basic average number of shares for the year ended December 31, 2015 includes 37 million representing the weighted average number of shares for the length of time the 87 million shares were outstanding during 2015.
(3)		In the year ended December 31, 2014, the difference between the diluted average number of shares and the basic average number of shares relates to share equivalents associated with outstanding employee stock options and awards. The diluted average number of shares for the year ended December 31, 2014 does not include any share equivalents related to the Notes or mandatory convertible preferred stock as their effect was anti-dilutive. In the year ended December 31, 2015, the diluted average number of shares does not include any share equivalents as their effect was anti-dilutive.

(1)		On November 19, 2014, Alcoa completed the acquisition of Firth Rixson. As a result, Alcoa’s Consolidated Balance Sheet as of December 31, 2014 included an estimate of the beginning balance sheet of Firth Rixson. This estimate resulted in the allocation of $1,227 of the $3,125 purchase price (includes $130 of contingent consideration) to various assets, primarily Properties, plants, and equipment, and liabilities with the difference included in Goodwill. In 2015, an adjustment of $128 was recorded to decrease the initial amount recorded as Goodwill. This adjustment was based on management’s final allocation of the purchase price, which was based, in part, on information from a third-party valuation of the acquired business.
(2)		The Consolidated Balance Sheet as of December 31, 2015 includes amounts related to the acquisition of RTI International Metals. These amounts are composed of an estimate of the beginning balance sheet of RTI International Metals on the acquisition date, July 23, 2015, and the changes in these balances from July 23, 2015 through December 31, 2015. The estimate of the beginning balance sheet is the result of allocating $625 of the $870 purchase price to various assets, primarily Properties, plants, and equipment, and liabilities with the difference included in Goodwill. The final allocation of the purchase price will be based, in part, on management’s review of information from a third-party valuation of the acquired business, which is expected to be completed in the second quarter of 2016.
(3)		In the fourth quarter of 2015, Alcoa adopted changes issued by the Financial Accounting Standards Board to accounting for income taxes, which requires all deferred income tax assets and liabilities to be classified as noncurrent in a classified balance sheet. These changes were to become effective for Alcoa on January 1, 2017; however, management elected the early adoption provision. As such, all deferred income tax assets and liabilities were classified in the Deferred income taxes and Other noncurrent liabilities and deferred credits, respectively, line items on the December 31, 2015 Consolidated Balance Sheet. Additionally, management elected to update the December 31, 2014 Consolidated Balance Sheet for these changes for comparative purposes. As a result, $421 of current deferred income tax assets (previously reported in Prepaid expenses and other current assets) and $83 of current deferred income tax liabilities (previously reported in Taxes, including income taxes) were reclassified to the respective, aforementioned noncurrent asset and liability line items on the December 31, 2014 Consolidated Balance Sheet.

(1)		In the first quarter of 2015, management decided to reflect the net periodic benefit cost related to Alcoa-sponsored defined benefit pension plans as a separate line item in the Statement of Consolidated Cash Flows. In prior periods, a portion of this amount was reported in both the (Increase) in noncurrent assets (overfunded plans) and the (Decrease) in noncurrent liabilities (underfunded plans) line items. As a result, the Statement of Consolidated Cash Flows for the year ended December 31, 2014 was revised to conform to the current period presentation.
(2)		The (Increase) in noncurrent assets line item for the year ended December 31, 2015 includes a $300 prepayment related to a natural gas supply agreement for three alumina refineries in Western Australia, which are owned by Alcoa’s majority-owned subsidiary, Alcoa of Australia Limited.
(3)		In the first quarter of 2014, holders of $575 principal amount of Alcoa’s 5.25% Convertible Notes due March 15, 2014 (the “Notes”) exercised their option to convert the Notes into 89 million shares of Alcoa common stock. This transaction was not reflected in the Statement of Consolidated Cash Flows for the year ended December 31, 2014 as it represents a noncash financing activity.
(4)		In the fourth quarter of 2014, Alcoa paid $2,995 (net of cash acquired) to acquire Firth Rixson. A portion of this consideration was paid through the issuance of 37 million shares in Alcoa common stock valued at $610. The issuance of common stock was not reflected in the Statement of Consolidated Cash Flows for the year ended December 31, 2014 as it represents a noncash investing activity.
		In the third quarter of 2015, Alcoa issued 87 million shares of its common stock valued at $870 to acquire RTI International Metals. The issuance of common stock was not reflected in the Statement of Consolidated Cash Flows for the year ended December 31, 2015 as it represents a noncash investing activity. However, through this acquisition, Alcoa acquired $302 in cash, which was reflected as a cash inflow in the Acquisitions, net of cash acquired line item on the Statement of Consolidated Cash Flows for the year ended December 31, 2015.
(5)		Proceeds from the sale of assets and businesses for the year ended December 31, 2015 includes a cash outflow for cash paid as a result of post-closing adjustments associated with the December 2014 divestiture of three rolling mills in Spain and France.

The difference between certain segment totals and consolidated amounts is in Corporate.
(1)		Effective in the second quarter of 2015, management removed the impact of metal price lag from the results of the Global Rolled Products and Engineered Products and Solutions (now Engineered Products and Solutions and Transportation and Construction Solutions – see footnote 2 below) segments in order to enhance the visibility of the underlying operating performance of these businesses. Metal price lag describes the timing difference created when the average price of metal sold differs from the average cost of the metal when purchased by the respective segment. The impact of metal price lag is now reported as a separate line item in Alcoa’s reconciliation of total segment ATOI to consolidated net income (loss) attributable to Alcoa. As a result, this change does not impact the consolidated results of Alcoa. Segment information for all prior periods presented was updated to reflect this change.
(2)		In the third quarter of 2015, management approved a realignment of Alcoa’s Engineered Products and Solutions segment due to the expansion of this part of Alcoa’s business portfolio through both organic and inorganic growth. This realignment consisted of moving both the Alcoa Wheel and Transportation Products and Building and Construction Systems business units to a new reportable segment named Transportation and Construction Solutions. Additionally, the Latin American soft alloy extrusions business previously included in Corporate was moved into the new Transportation and Construction Solutions segment. The remaining Engineered Products and Solutions segment consists of the Alcoa Fastening Systems and Rings (renamed to include portions of the Firth Rixson business acquired in November 2014), Alcoa Power and Propulsion (includes the TITAL business acquired in March 2015), Alcoa Forgings and Extrusions (includes the other portions of Firth Rixson), and Alcoa Titanium and Engineered Products (a new business unit that represents the RTI International Metals business acquired in July 2015) business units. Segment information for all prior periods presented was updated to reflect the new segment structure.

Net income (loss) attributable to Alcoa – as adjusted is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management reviews the operating results of Alcoa excluding the impacts of restructuring and other charges, discrete tax items, and other special items (collectively, “special items”). There can be no assurances that additional special items will not occur in future periods. To compensate for this limitation, management believes that it is appropriate to consider both Net income (loss) attributable to Alcoa determined under GAAP as well as Net income attributable to Alcoa – as adjusted.
(1)		Discrete tax items include the following:
•		for the quarter ended December 31, 2015, a charge for valuation allowances related to certain U.S. and Iceland deferred tax assets ($190) and a net benefit for a number of small items ($3);
•		for the quarter ended September 30, 2015, a net charge for a number of small items;
•		for the quarter ended December 31, 2014, a charge for the remeasurement of certain deferred tax assets of a subsidiary in Spain due to a tax rate change ($16), a benefit for an adjustment to the remeasurement of certain deferred tax assets of a subsidiary in Brazil due to a tax rate change ($3), and a net charge for a number of small items ($3);
•		for the year ended December 31, 2015, a charge for valuation allowances related to certain U.S. and Iceland deferred tax assets ($190) and a net benefit for a number of small items ($4); and
•		for the year ended December 31, 2014, a charge for the remeasurement of certain deferred tax assets of a subsidiary in Brazil due to a tax rate change ($31), a charge for the remeasurement of certain deferred tax assets of a subsidiary in Spain due to a tax rate change ($16), and a net benefit for a number of other items ($14).
(2)		Other special items include the following:
•		for the quarter ended December 31, 2015, a write-down of inventory related to the permanent closure or temporary curtailment of various facilities in Suriname and the United States ($28), an impairment of goodwill related to the soft alloy extrusions business in Brazil ($25), costs associated with the planned separation of Alcoa ($12), a net unfavorable change in certain mark-to-market energy derivative contracts ($5), and an unfavorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($2);
•		for the quarter ended September 30, 2015, an unfavorable tax impact resulting from the difference between Alcoa’s consolidated estimated annual effective tax rate and the statutory rates applicable to special items ($27), a gain on the sale of land in the United States and an equity investment in a China rolling mill ($25), costs associated with the planned separation of Alcoa and the acquisition of RTI International Metals ($22), a favorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($16), a write-down of inventory related to a refinery in Suriname ($13), and a net unfavorable change in certain mark-to-market energy derivative contracts ($10);
•		for the quarter ended December 31, 2014, an unfavorable tax impact resulting from the difference between Alcoa’s consolidated estimated annual effective tax rate and the statutory rates applicable to special items ($81), a favorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($44), costs associated with the acquisition of Firth Rixson and the then-planned acquisition of TITAL ($22), and a net favorable change in certain mark-to-market energy derivative contracts ($2);

•		for the year ended December 31, 2014, a write-down of inventory related to the permanent closure of various facilities in Italy, Australia, and the United States ($47), costs associated with the acquisition of Firth Rixson and the then-planned acquisition of TITAL ($47), a gain on the sale of both a mining interest in Suriname and an equity investment in a China rolling mill ($20), an unfavorable impact related to the restart of one potline at the joint venture in Saudi Arabia that was previously shut down due to a period of pot instability ($19), costs associated with preparation for and ratification of a new labor agreement with the United Steelworkers ($11), a net unfavorable change in certain mark-to-market energy derivative contracts ($6), and a loss on the write-down of an asset to fair value ($2).
(3)		The average number of shares applicable to diluted EPS for Net income (loss) attributable to Alcoa common shareholders excludes certain share equivalents as their effect was anti-dilutive (see footnote 3 to the Statement of Consolidated Operations). However, certain of these share equivalents may become dilutive in the EPS calculation applicable to Net income attributable to Alcoa common shareholders – as adjusted due to a larger and/or positive numerator. Specifically:
•		for the quarter ended December 31, 2015, share equivalents associated with outstanding employee stock options and awards were dilutive based on Net income attributable to Alcoa common shareholders – as adjusted, resulting in a diluted average number of shares of 1,324,378,133;
•		for the quarter ended September 30, 2015, no additional share equivalents were dilutive based on Net income attributable to Alcoa common shareholders – as adjusted, resulting in a diluted average number of shares of 1,294,392,945;
•		for the quarter ended December 31, 2014, share equivalents associated with mandatory convertible preferred stock were dilutive based on Net income attributable to Alcoa common shareholders – as adjusted, resulting in a diluted average number of shares of 1,294,701,805 (the subtraction of preferred stock dividends declared from the numerator (see footnote 1 to the Statement of Consolidated Operations) needs to be reversed since the related mandatory convertible preferred stock was dilutive);
•		for the year ended December 31, 2015, share equivalents associated with both outstanding employee stock options and awards and convertible notes related to the acquisition of RTI International Metals were dilutive based on Net income attributable to Alcoa common shareholders – as adjusted, resulting in a diluted average number of shares of 1,288,633,988 (after-tax interest expense of $8 needs to be added back to the numerator since the convertible notes were dilutive); and
•		for the year ended December 31, 2014, share equivalents associated with both Alcoa’s 5.25% convertible notes and mandatory convertible preferred stock were dilutive based on Net income attributable to Alcoa common shareholders – as adjusted, resulting in a diluted average number of shares of 1,217,720,724 (after-tax interest expense of $6 needs to be added back to the numerator since the convertible notes were dilutive and the subtraction of $19 of the preferred stock dividends declared from the numerator (see footnote 1 to the Statement of Consolidated Operations) needs to be reversed since the related mandatory convertible preferred stock was dilutive).

Alcoa’s definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add-back for depreciation, depletion, and amortization. Net margin is equivalent to Sales minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; Research and development expenses; and Provision for depreciation, depletion, and amortization. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because Adjusted EBITDA provides additional information with respect to Alcoa’s operating performance and the Company’s ability to meet its financial obligations. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.

(1)		Effective in the second quarter of 2015, management removed the impact of metal price lag from the results of the Global Rolled Products segment in order to enhance the visibility of the underlying operating performance of this business. Metal price lag describes the timing difference created when the average price of metal sold differs from the average cost of the metal when purchased by this segment. The impact of metal price lag is now reported as a separate line item in Alcoa’s reconciliation of total segment ATOI to consolidated net income (loss) attributable to Alcoa. As a result, this change does not impact the consolidated results of Alcoa. Segment information for all prior periods presented was updated to reflect this change. See Segment Information above for additional information.

(1)		Effective in the second quarter of 2015, management removed the impact of metal price lag from the results of the Engineered Products and Solutions (now Engineered Products and Solutions and Transportation and Construction Solutions – see footnote 2 below) segment in order to enhance the visibility of the underlying operating performance of this business. Metal price lag describes the timing difference created when the average price of metal sold differs from the average cost of the metal when purchased by this segment. The impact of metal price lag is now reported as a separate line item in Alcoa’s reconciliation of total segment ATOI to consolidated net income (loss) attributable to Alcoa. As a result, this change does not impact the consolidated results of Alcoa. Segment information for all prior periods presented was updated to reflect this change. See Segment Information above for additional information.
(2)		In the third quarter of 2015, management approved a realignment of Alcoa’s Engineered Products and Solutions segment due to the expansion of this part of Alcoa’s business portfolio through both organic and inorganic growth. This realignment consisted of moving both the Alcoa Wheel and Transportation Products and Building and Construction Systems business units to a new reportable segment named Transportation and Construction Solutions. Additionally, the Latin American soft alloy extrusions business previously included in Corporate was moved into the new Transportation and Construction Solutions segment. The remaining Engineered Products and Solutions segment consists of the Alcoa Fastening Systems and Rings (renamed to include portions of the Firth Rixson business acquired in November 2014), Alcoa Power and Propulsion (includes the TITAL business acquired in March 2015), Alcoa Forgings and Extrusions (includes the other portions of Firth Rixson), and Alcoa Titanium and Engineered Products (a new business unit that represents the RTI International Metals business acquired in July 2015) business units. Segment information for all prior periods presented was updated to reflect the new segment structure.

Free cash flow		$	989			$	152			$	467			$	455			$	402

Free Cash Flow is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management reviews cash flows generated from operations after taking into consideration capital expenditures due to the fact that these expenditures are considered necessary to maintain and expand Alcoa’s asset base and are expected to generate future cash flows from operations. It is important to note that Free Cash Flow does not represent the residual cash flow available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements, are not deducted from the measure.

Days Working Capital = Working Capital divided by (Sales/number of days in the quarter).
(1)		The deferred purchase price receivable relates to an arrangement to sell certain customer receivables to several financial institutions on a recurring basis. Alcoa is adding back this receivable for the purposes of the Days Working Capital calculation.
(2)		The Working Capital for each period presented represents an average quarter Working Capital, which reflects the capital tied up during a given quarter. As such, the components of Working Capital for each period presented represent the average of the ending balances in each of the three months during the respective quarter.
(3)		In the quarters ended September 30, 2015 and December 31, 2015, Working Capital and Sales include $708 and $387, respectively, and $924 and $422 respectively, related to three acquisitions, Firth Rixson (November 2014), TITAL (March 2015), and RTI International Metals (July 2015). Excluding these amounts, Days Working Capital was 31 and 29 for the quarters ended September 30, 2015 and December 31, 2015, respectively.

Net debt is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management assesses Alcoa’s leverage position after factoring in available cash that could be used to repay outstanding debt.
