ABOUT
Alumina 
Limited
Alumina Limited has a 
unique investment in some 
of the world’s highest 
quality alumina assets
The Annual Report is presented in  
US dollars, unless otherwise specified.
Alumina Limited is the 40% partner in the AWAC joint 
venture with a portfolio of assets in Australia, Brazil, 
Spain, Saudi Arabia and Guinea, including globally 
leading bauxite mines and alumina refineries. Alumina 
Limited is an Australian company listed on the Australian 
Securities Exchange (ASX) and trades on the OTC 
Market in the US. AWAC also has a 55 per cent interest 
in the Portland aluminium smelter in Victoria, Australia.
AWAC’s joint venture partner and operator is Alcoa 
Corporation. The AWAC joint venture was formed in 
1994 and our relationship with Alcoa dates back to  
the early 1960s when Western Mining Corporation 
(now called Alumina Limited) began to explore bauxite 
deposits and other resources in the Darling Ranges  
of Western Australia. Alcoa Inc. was invited to join the 
project to provide technology, aluminium expertise 
and finance.
Over the following years the venture grew to include 
refineries and smelter interests as the partners sought  
to take opportunities to expand the business. By 1990, 
WMC Limited’s interests in Alcoa of Australia had 
grown through acquiring the interests of other  
minority participants, other than Alcoa.
WMC Limited and Alcoa Inc. combined their  
respective bauxite, alumina and alumina-based 
chemicals businesses and investments and some 
selected smelting operations to create Alcoa World 
Alumina and Chemicals (AWAC) in January 1995. 
Alumina Limited was created on 11 December 2002 
when WMC Limited’s alumina assets were demerged 
from the nickel, copper and fertiliser businesses.

AT A GLANCE
Focused  
investment  
in AWAC
In 2023 Alumina Limited 
posted a net loss after tax 
of $150.1 million compared 
to a net profit after tax of 
$104.0 million in 2022.
Excluding significant items, net loss after  
tax would have been $91.9 million dollars 
(2022: $109.3 million net profit after tax). 
The Company did not declare a dividend  
in respect of the 2023 year.

Alumina LimitedAnnual Report 20233
AWAC’s EBITDA for 2023 was $164.5 million 
(2022: $817.1 million) and excluding 
significant items would have been $209.5 
million (2022: $814.6 million). The decrease  
in AWAC’s 2023 net profit is principally 
attributable to reduced alumina production 
and higher cash costs of production.
In 2023, alumina prices were tightly range bound,  
with a maximum of between $371 per tonne and a 
minimum of $325 per tonne for Platts WA FOB. The 
average Platts WA FOB was $343 per tonne (2022: 
$362 per tonne). The average realised alumina price 
was $352 per tonne in 2023, a decrease of 5.1% 
relative to 2022. 
AWAC’s cash cost of alumina production increased  
by 1.3% to $308 per tonne. Key factors driving this 
were lower bauxite grade, higher caustic prices and 
conversion costs.
The margin1 was $44 per tonne of alumina (2022:  
$67 per tonne).

Alumina Limited
Chairman and  
CEO Report
2023 was a highly challenging year for our company. 
Accordingly, we took steps to weather the storm  
and we supported the hard decisions necessary  
to turnaround AWAC’s performance.
Safety
In 2023 there were no fatalities and AWAC has 
maintained fatality free operations since 2017. There 
was one serious injury and AWAC is continuing to 
focus on improving its performance, including in 
relation to issues such as chemical burns which have 
been challenging for AWAC and the industry  
more generally.
Weathering the storm
AWAC’s alumina production of 10.3 million tonnes  
in 2023 was a decline of 1.5 million tonnes compared 
to the previous year. This was a result of a controlled 
reduction in Kwinana production due to a shortage  
of gas, the processing of lower grade bauxite in 
Western Australia, San Ciprian operating at around 
50% capacity due to high natural gas prices and 
conveyor failure at the port in Alumar.
Alumina Limited was required to make $159.1  
million net contributions to AWAC entities during  
the year (2022: net receipts $166.5 million dollars), 
disappointingly resulting in insufficient free cash flow 
to facilitate a dividend payment to shareholders. 
We were, however, well placed to weather the storm.  
In June, 2023 we renegotiated our existing bank 
facility, increasing our total facility limit from $350 
million to $500 million. As of 31 December 2023,  
our net debt was $294.3 million with maturities ranging 
from October 2025 to June 2027.
Transitioning approval processes – 
Western Australia
In December 2023, we were pleased to announce  
that the Western Australian government had granted 
Alcoa of Australia approval for its 2023-2027 Mining 
and Management Program (MMP), in respect of the 
Huntly and Willowdale bauxite mines. 
Subsequently, the government also granted an 
exemption to allow AWAC to continue its mining 
operations while the WA Environmental Protection 
Authority (EPA) assesses the MMP. This resolved  
a significant level of uncertainty which had cast a 
shadow over the Company for much of 2023.
Under the approvals, AWAC agreed to a range  
of conditions addressing key environmental factors  
that include the protection of drinking water and 
biodiversity along with accelerated forest rehabilitation. 
These commitments provide significantly enhanced 
environmental protections, allowing a transition to a 
more contemporary process for future mining areas. 
AWAC continues to progress approvals for its next 
major mine regions (Myara North and Holyoak) through 
the contemporary WA EPA process, with the highest 
level Public Environmental Review being applied.
Improving the portfolio for the future
The focus now for AWAC and our Company is 
continuing to take action to improve our portfolio. 
In December 2023, Alcoa announced that actions are 
being undertaken to further reduce losses in relation to 
the San Ciprian refinery. This work continues, including 
ongoing discussions with workers unions and relevant 
government agencies.
Annual Report 20235
On 9 January 2024, Alcoa of Australia made the difficult 
decision to fully curtail the Kwinana Alumina Refinery  
in Western Australia. Kwinana had been the foundation 
stone for AWAC’s operations in Western Australia since  
it was commissioned in 1963. 
Through this time Kwinana, provided valuable feedstock  
for AWAC’s Point Henry and Portland Smelters, as well as 
other third-party customers. It had a nameplate capacity of 
2.2 million tonnes of alumina, and throughout its lifetime 
had produced approximately 95 million tonnes of alumina, 
which would equate to roughly 47.5 million tonnes of 
aluminium, or approximately 3,393 billion beer cans. 
Unfortunately, a combination of age, scale, maintenance 
and bauxite grades had increased its costs of production 
to an uneconomic and unsustainable level. 
We thank all those who worked at Kwinana and 
acknowledge their dedication and service to AWAC  
over the years.
Board updates
On 15 January 2024, we were pleased to welcome Alistair 
Field to the Board. Mr Field brings extensive operational 
experience and commercial acumen and his appointment 
was an important step in the Board’s succession and 
renewal plan.
Robust markets
Aluminium remains vital in a decarbonised world.  
An example of this is that in December 2023, the 
Australian Government released a new Strategic Materials 
List1 which includes aluminium, among other materials,  
as an essential commodity for the world’s clean energy 
technologies, such as solar, batteries and electric  
vehicles, and electrical transmission. 
In 2023, the alumina market was relatively tight, with 
alumina prices, ranging between $325 and $371 per 
tonne for Platts WA FOB. In the first half, alumina prices 
increased as a result of curtailed Kwinana production, 
however prices then decreased in response to weaker 
aluminium demand. In the second half of the year, prices 
increased due to increased demand from Chinese 
smelters, bauxite supply concerns in Guinea and supply 
disruptions in China. We expect the market to remain tight 
in 2024. No new RoW greenfield metallurgical alumina 
project is expected in 2024. Brownfield expansions  
and production ramp-ups are likely to be somewhat  
offset by supply disruptions in Australia. With steady 
demand growth from primary aluminium smelters,  
RoW metallurgical alumina market in 2024 is forecast  
to be in further deficit compared to 2023. 
The Alcoa Offer
Shareholders will be aware that Alumina has entered into 
a scheme implementation deed with Alcoa Corporation in 
relation to a proposal for Alcoa to acquire Alumina. Under 
the terms of the deed, eligible Alumina shareholders will 
be entitled to receive Alcoa common stock in the form  
of ASX-listed Alcoa CHESS Depositary Interests (CDIs). 
Alcoa has agreed to establish a foreign exempt listing  
on the Australian Securities Exchange (ASX), which would 
enable Alumina shareholders to trade shares of Alcoa 
common stock via CDIs on the ASX, in the same way  
they would normally trade ASX-listed Alumina shares.
Further information about the proposal is set out in 
Alumina’s ASX release of 12 March 2024 and the Alumina 
website at www.aluminalimited.com/alcoa-offer/.
The Board has considered the proposal in great detail  
and is working towards an outcome that is most beneficial 
to Alumina shareholders.

Sustainability
ESG Investor Briefing
In 2023 Alumina Limited held its third annual ESG 
Investor Briefing (available on the Company’s website), 
focussing on key current and emerging ESG matters 
for Alumina Limited and AWAC, including biodiversity 
and rehabilitation, energy and emissions intensity, 
water management and modern slavery/human rights.
The ESG Briefing highlighted AWAC’s unique 
concentration of low-cost and low emissions refineries 
with AWAC emissions intensity metrics continuing  
to improve.
The ESG Briefing also provided an update on 
impoundment management. Impoundment 
management has been a key focus of the Board of 
Alumina Limited for a number of years. The Company 
understands the seriousness of the joint venture 
operating large scale residue storages areas and the 
importance of safety and meeting standards. Alcoa, as 
an ICMM member, voluntarily committed to conform to 
the Global Industry Standard on Tailings Management 
(GISTM). As part of this commitment, all AWAC tailings’ 
dams with a consequence category rating of ‘Very 
high’ or ‘Extreme’ were compliant by August 2023.  
This was an important achievement for the joint 
venture, with the remaining facilities due to be in 
conformance by August 2025.
Alumina LimitedAnnual Report 20237
Modernising processes and practices – 
Western Australia
The upcoming curtailment of the Kwinana refinery  
will further reduce AWAC’s emissions.
Engagement with relevant government agencies on 
mine plan and related approvals was a key focus for 
AWAC during 2023. Alumina Limited provided regular 
updates on progress, including at its 2023 Half-Year 
Results. Alumina Limited announced on 14 December 
2023 that the Western Australian Government had 
made decisions allowing AWAC to continue bauxite 
mining and downstream alumina refining in WA, with 
AWAC committing to a range of conditions addressing 
key environmental factors including the protection of 
drinking water and biodiversity along with accelerated 
forest rehabilitation. 
Safeguard mechanism
In July 2023, The Australian Government implemented 
its reforms to the Safeguard Mechanism. The key 
aspect of the reforms is to require large industrial 
“Safeguard Facilities” to keep direct greenhouse gas 
emissions at or below baselines in line with Australia’s 
climate targets of 43% below 2005 levels by 2030 and 
net zero by 2050. Safeguard Facilities are required  
to reduce their emissions in a manner known as the 
“hybrid model”.
Whilst all AWAC’s Australian facilities (except the 
Willowdale mine) are captured within the policy, 
AWAC’s alumina refineries are all below industry 
average, having the lowest emissions intensity  
in Australia. As a result, the policy is expected  
to have minimal impact on AWAC’s operations.  
Aluminium Stewardship Initiative (ASI)
In 2023, the Portland smelter and CBG mine (non-
AWAC operated) both received ASI certification.  
The ASI works together with producers, users and 
stakeholders in the aluminium value chain to 
collaboratively foster responsible production,  
sourcing and stewardship of aluminium. All nine  
of AWAC’s operating locations are now certified  
to the ASI Performance Standard.
IAI Greenhouse Gas Initiative
The International Aluminium Institute (IAI) launched  
a new initiative to transparently and publicly track  
the ambition and progress of its member companies’ 
greenhouse gas emission reductions.
By signing up to IAI’s initiative in December 2023, 
Alumina Limited demonstrated its commitment to 
continue to focus on transparency and reporting of  
its emissions whilst striving to achieve its net zero  
by 2050 ambition.
This commitment aligns with Alumina Limited’s own 
goals and emphasises that the aluminium industry as  
a whole understands the importance of transparency 
and continuing to take meaningful actions to achieve 
global climate targets.

Insurance of Officers
During or since the end of the financial year, the  
Group has paid the premiums in respect of a contract 
to insure Directors and other officers of the Group 
against liabilities incurred in the performance of their 
duties on behalf of the Group. The officers of the 
Group covered by the insurance policy include any 
natural person acting in the course of duties for the 
Group who is or was a Director, secretary or executive 
officer as well as other employees. The Company is 
prohibited, under the terms of the insurance contract, 
from disclosing details of the nature of liability insured 
against and the amount of the premium.
Rule 75 of the Company’s Constitution requires the 
Company to indemnify each officer of the Company 
(and, if the Board of the Company considers it 
appropriate, any officer of a wholly owned subsidiary 
of the Company) out of the assets of the Company 
against any liability incurred by the officer in or arising 
out of the conduct of the business of the Company or 
the relevant wholly-owned subsidiary or in or arising 
out of the discharge of the duties of the officer, where 
that liability is owed to a person other than the 
Company or a related body corporate of the Company. 
This requirement does not apply to the extent that the 
liability arises out of conduct on the part of the officer 
which involved a lack of good faith, or to the extent 
that the Company is otherwise precluded by law from 
providing an indemnity. It only applies to the extent 
and for the amount that the officer is not otherwise

changes in the nature of the principal activities of the 
Group during the financial year.
Review of operations and results
The financial results for the Group include the 
12-month results of AWAC and associated corporate 
activities. The Group’s net loss after tax for the 2023 
financial year attributable to members of the Company 
was US$150.1 million (2022: US$104.0 million net 
profit after tax). Excluding significant items, there 
would have been a net loss after tax of US$91.9 million 
(2022: US$109.3 million net profit after tax). For further 
information on the operations of the Group during the 
financial year and the results of these operations refer

Operating and  
financial review
1. Strategy and business model
Matters requiring a super-majority vote include:
 · change of the scope of AWAC
 · change in the dividend policy
 · equity calls on behalf of AWAC totalling, in any  
one year, in excess of $1 billion
 · acquisitions, divestitures, expansions and 
curtailments exceeding 2 million tonnes per annum 
of bauxite or 0.5 million tonnes per annum of 
alumina or which have a sale price, acquisition price, 
or project total capital cost of $50 million or greater1 
 · entry into related party transactions of $50 million  
or greater
 · entry into financial derivatives, hedges and  
other commodity price or interest rate protection 
mechanisms
 · decision to file for insolvency in respect of any  
AWAC company.
Under the general direction of the Strategic Council, 
Alcoa is the “industrial leader” and provides the 
operating management of AWAC and of all affiliated 
operating entities within AWAC.
Business model
Alumina Limited represents a unique investment in 
globally leading bauxite mines and alumina refineries 
through its 40% investment in Alcoa World Alumina 
and Chemicals (AWAC). AWAC also has a 55% interest 
in the Portland aluminium smelter in Victoria, Australia.
The Company provides a clean look-through to 
AWAC’s underlying performance. This is possible 
because the financial policies of AWAC ensure there  
is modest leverage in AWAC and the distribution 
policies of AWAC require free cash flows to be paid  
to its shareholders.
AWAC was formed on 1 January 1995 by WMC and 
Alcoa Inc. combining their respective global bauxite, 
alumina and alumina-based chemicals business and 
investments and their respective aluminium smelting 
operations in Australia. Following the separation of 
Alcoa Inc. into Alcoa Corporation and Arconic Inc. on  
1 November 2016, Alcoa Corporation (Alcoa) replaced 
Alcoa Inc as Alumina Limited’s partner in the AWAC 
joint venture. Alcoa owns the 60% interest in the joint 
venture and manages the day-to-day operations.
The Strategic Council is the principal forum for Alcoa 
and Alumina Limited to provide direction and counsel 
to the AWAC entities in respect of strategic and policy 
matters. The Strategic Council has five members, three 
appointed by Alcoa (of which one is Chairman) and 
two by Alumina Limited (of which one is the Deputy 
Chairman). Decisions are made by majority vote  
except for matters which require a “super-majority” 
vote, which is a vote of at least 80% of the members 
appointed to the Strategic Council.
1. In the case of curtailment, super-majority vote only applies 
to full curtailment and does not apply where there have been 
two consecutive quarters of loss at the relevant operations.

Alumina Limited is entitled to representation in 
proportion to its ownership interest on the board of 
each entity in the AWAC structure and is currently 
represented on the boards of Alcoa of Australia Ltd 
(AofA), AWA Saudi Ltda. and Alcoa World Alumina  
LLC (AWA LLC). In addition to the Strategic Council 
meetings, Alumina Limited’s Management and Board 
visit and review AWAC’s operations, and participate  
in segment and location meetings.
Subject to the exclusivity provisions of the AWAC 
agreements, AWAC is the exclusive vehicle for the 
pursuit of Alumina Limited’s and Alcoa’s (and their 
related corporations as defined) interests in the 
bauxite, alumina and inorganic industrial chemicals 
businesses, and neither party can compete with AWAC 
so long as they maintain an ownership interest in 
AWAC. In addition, Alumina Limited may not compete 
with the businesses of the integrated operations of 
AWAC (being the primary aluminium smelting and 
fabricating facilities and certain ancillary facilities that 
existed at the formation of AWAC). The exclusivity 
provisions would terminate immediately on and from  
a change in control of either Alumina Limited or Alcoa.
Also, effective immediately on and from a change  
of control of Alcoa or Alumina Limited there is an 
increased opportunity for development projects  
and expansions, whereby if either Alumina Limited  
or Alcoa Corporation wishes to expand an existing 
AWAC operation, develop a new project on AWAC 
tenements or pursue a project outside of AWAC,  
it is entitled to do so on a sole basis after providing 
180 days for the other party to explore joint 
participation in the proposed project.
Strategy analysis
A partner that avails itself of such an opportunity would 
pay for all costs related to the project, including for 
AWAC resources and shared facilities used, and would 
be entitled to all of the project’s resulting off-take.
If there is a change of control of Alumina Limited then:
 · Future alumina off-take rights, from a date nominated 
by Alumina Limited, Alumina Limited or its acquirer 
will be entitled to buy, subject to its 40% ownership 
cap:
 — its net short position (calculated as total 
consumption less total owned production  
per annum) of alumina at market price
for its internal consumption; plus
 — up to 1 million tonnes per annum alumina off-take, 
at market prices, which it may market and sell as it 
sees fit;
in all cases subject to AWAC third party customer 
contracts being satisfied;
 · Future bauxite off-take rights
 — from a date nominated by Alumina Limited, 
Alumina Limited or its acquirer will be entitled to 
buy, at market prices, up to its net short position  
of bauxite for internal consumption, subject to  
its 40% ownership cap and pre-existing bauxite 
sales contracts.
Alumina Limited is primarily focused on investing 
in long-life, low-cost bauxite and alumina assets. 
Alumina Limited does this currently through the 
AWAC joint venture with its partner, Alcoa.
Alumina Limited and Alcoa are different 
companies with different shareholders, different 
governance requirements and different objectives. 
While AWAC is governed by constitutional 
documents, in a practical sense, the reconciliation 
of the differing interests requires challenge, 
debate and negotiation. To do this well, Alumina 
Limited needs to have (and has) an independent 
understanding of the bauxite, alumina and 
aluminium market and views on the impact  
of changes in the market, in particular  
around capacity investment, pricing and the 
development of the global markets. Through 
the role of Alumina Limited representatives on 
the Strategic Council and AWAC entity boards 
and working with Alcoa, Alumina Limited 
contributes to the strategic and high-level 
commercial actions of AWAC.

2. Principal risks
The Group’s risk management processes are 
summarised in the Corporate Governance 
Statement located on the Company website at 
www.aluminalimited.com/about-governance.
The Company maintains a formal Risk Management 
Framework (RMF), which is overseen by the Audit  
and Risk Management Committee (ARMC). The RMF 
contains the following elements:
 ·  Risk management policy, which is approved and 
reviewed annually by the ARMC, as the delegate  
of the Board of Directors.
 · Document describing the risk management process 
including reporting and escalation procedures.
 · Risk management strategy, which explains how 
Alumina identifies, mitigates, manages, monitors, 
reports its material risks.
SUMMARY OF KEY BUSINESS RISKS
 · Risk appetite statement, which contains risk appetite 
and tolerance statements that are approved and 
monitored by the ARMC.
 · Risk profile, which captures the material risks of 
Alumina, and for each risk provides a description, an 
allocated risk owner, appropriate risk management 
strategy, controls, a forward action plan, and an 
inherent/residual risk rating based on probability  
and impact of a risk eventuating.
Set out on pages 23 to 30 are some of the key business 
risks faced by Alumina Limited that could adversely 
affect the achievement of financial performance or 
financial outcomes. There may be other risks not listed 
on pages 23 to 30 associated with an investment in 
Alumina Limited. In addition, certain risks have been 
excluded as they contain confidential information,  
or disclosure may result in unreasonable prejudice  
to Alumina Limited.
Risk Title
Description
Response
AWAC seeks to identify ways in  
which to lower costs of production 
and thus achieve a low position on 
the cost curve. A low position on the 
cost curve allows AWAC to remain 
competitive in the event of 
unfavourable market movements.
Market Risks
Strategic 
positioning  
to market  
exposure
Commodity Prices
AWAC’s, and hence Alumina Limited’s, performance is 
predominantly affected by the market price of alumina, and  
to some extent the market prices of bauxite and aluminium.  
Market prices are affected by numerous factors outside of  
Alumina Limited’s control.
These include the overall performance of world economies,  
the related cyclicality of industries that are significant consumers  
of aluminium and movement in production disproportionate  
to demand (whether as a result of changes to production levels  
at existing facilities or the development of new facilities by 
competitors). An alumina and/or aluminium market in supply 
surplus may lead to downward price pressure. Global growth may 
slow, reducing aluminium consumption, and hence aluminium and 
alumina demand, which may put downward pressure on bauxite/
alumina/aluminium prices. A fall in the market prices of bauxite, 
alumina and aluminium can adversely affect Alumina Limited’s 
financial performance.
In addition, new refineries to be built at low capital and operating 
cost could increase the supply of alumina globally, which could 
lead to a fall in the market price of alumina.
Emerging competitors, that may be subsidised directly or  
indirectly by government, entering the alumina market may  
cause overcapacity in the industry which may result in AWAC 
losing sales or in depressed prices. 
A technology breakthrough could lower Chinese alumina 
production costs, creating a structural change in the alumina  
and aluminium markets. 
A sustained increase in freight costs could disadvantage  
AWAC’s competitiveness.

Risk Title
Description
Response
Strategic 
positioning  
to market  
exposure 
continued
Foreign exchange
While a significant proportion of AWAC’s costs are incurred  
in Australian dollars, its sales are denominated in US dollars. 
Accordingly, AWAC and Alumina’s Limited’s future profitability can 
be adversely affected by a strengthening of the Australian dollar 
against the US dollar and a strengthening against the US dollar of 
other currencies in which operating or capital costs are incurred by 
AWAC outside Australia, including the Brazilian Real. Also, given 
that China is a significant part of the world alumina and aluminium 
markets, fluctuations in the Chinese Renminbi against the US dollar 
could have some impact on other parts of the industry, for example 
the cost of bauxite which could affect Chinese refineries cost of 
production, and the China alumina import parity price.
AWAC and Alumina Limited  
generally do not undertake hedging 
activities to manage this risk.
Customers
AWAC’s relationships with key customers for the supply of alumina 
(including Alcoa) are important to AWAC’s financial performance. 
The loss of key customers (including through backward integration) 
or changes to sales agreements could adversely affect AWAC’s and 
Alumina Limited’s financial performance. There is also a risk that 
AWAC may not be able to fulfil contracted customer alumina 
volume with AWAC’s own alumina production, and any shortfall  
will need to be sourced from the third-party alumina market. 
AWAC mitigates customer risk  
by having a broad customer base 
across many countries and regions, 
and having low-cost refineries. 
Additionally, remaining at the low  
end of the alumina greenhouse gas 
(GHG) emissions curve in the 
longer-term may make AWAC 
attractive to customers seeking 
relatively lower GHG alumina.
Energy  
security
Geopolitical
As AWAC operates in a Global environment, the Joint Venture  
is exposed to geopolitical risks that affect markets and operations, 
Geopolitical risk includes political instability, coups d’états, civil 
unrest, strikes and work stoppages, expropriation, nationalization  
of properties by a government, imposition of sanctions, changes to 
import or export regulations and fees, renegotiation, revocation or 
nullification of existing agreements, leases, licenses, and permits, 
and changes to mining royalty rules or laws.
AWAC’s refineries and the Portland smelter are heavy consumers 
of energy. There is a risk that there may be a lack of availability  
of energy or cost competitive energy to service AWAC’s facilities. 
This would be a threat to the viability and operation of assets 
through constrained cash flow, and ultimately reduced dividends 
to Alumina.
Additionally, in the future the requirement for low carbon  
energy sources is expected to become more important. There  
is a risk that the availability of low carbon energy sources may be 
scarce, and hence they may command a high price. It may also  
be possible that competitors gain access to low carbon energy  
(or new lower emissions technology) before AWAC, which may 
disadvantage AWAC from a carbon intensity and cost curve 
perspective. Additionally, new low emissions technologies may 
require large amounts of renewable electricity. There is a risk that 
such energy sources may not be available in sufficient quantity or 
at a competitive price.
AWAC’s energy requirements and 
contracting is regularly reviewed  
by Alcoa and Alumina through the 
Strategic Council, and Strategy and 
Operation meetings.
In Western Australia in particular, 
AWAC enters into long-term energy 
contracts, but may consider shorter-
term contracts if required. Conversely, 
the San Ciprian refinery has shorter 
term energy contracts and a higher 
proportion of floating arrangements 
that fluctuate with certain energy 
price benchmarks. Alumar utilises 
coal and fuel oil for energy which  
can fluctuate with market prices.
Additionally, Alumina regularly reviews 
relevant energy markets in order to 
maintain an independent view.
AWAC is also exploring technology 
changes, through its Refinery of the 
Future project, aiming to allow the 
electrification of its refineries. If 
successful, this would reduce reliance 
on fossil fuels such as natural gas.

Risk Title
Description
Response
Operational Risks
Some cost inputs are subject to 
long-term, fixed price contracts to 
increase the certainty of input pricing.
AWAC and Alumina Limited generally 
do not undertake hedging activities 
to manage this risk.
AWAC’s operating and maintenance 
systems and business continuity 
planning seek to minimise the impact 
of non-availability of key inputs.
AWAC’s portfolio restructuring and 
repositioning seeks to ensure that 
operations as a whole remain 
competitive.
AWAC also invests in capital 
expenditure projects intended to 
maintain assets and reduce cash  
costs over the long-term.
AWAC has policies in place to 
maintain inventory, multiple  
suppliers, insurance, and long-term 
maintenance and CAPEX programs.
Alumina Limited has representatives 
on AWAC boards, and has frequent 
briefings in respect of permits. 
AWAC entities, such as Alcoa of 
Australia, have meetings with relevant 
regulators to discuss mining permits.
Operating  
costs
Production
Regulatory 
approvals and 
permits
AWAC’s operations are subject to conditions beyond its control 
that may increase its costs (including due to foreign exchange 
rates) or decrease its production, including increases in the cost  
of key inputs (including energy, raw materials, labour, caustic and 
freight), the non-availability of key inputs (including secure energy 
and bauxite), weather and natural disasters, fires or explosions  
at facilities, unexpected maintenance or technical problems, 
unplanned operational failure, key equipment failures, disruptions 
to, or other problems with, infrastructure and supply.
In addition, industrial disruptions, work stoppages, refurbishments 
and accidents at operations may adversely affect profitability.
AWAC may also be required from time to time to invest in 
sustaining capital expenditure projects in order to maintain the 
production levels of our facilities, asset integrity, and AWAC’s 
position on the relevant cost curve. Significant capital expenditure 
may reduce distributions to Alumina Limited from AWAC whilst 
projects are being funded. 
Examples of such capital expenditure include mine/crusher  
moves, impoundments (including press filtration), energy 
generation, or projects to abate AWAC’s carbon emissions.
Capital expenditure may be greater than planned and expected 
results, including production rates, may not be achieved.
Increases to operating costs reduce the profitability of AWAC, 
which decrease distributions to Alumina.
Major operational failures may restrict the output of alumina or 
aluminium. These may be caused by mechanical or plant failure,  
an “act of God”, supply chain disruptions, pandemics, material 
decline (or denial of access) in bauxite reserves, industrial relations 
disputes, regulatory issues, deferral of expenditures, or the loss  
of key personnel.
Such unplanned operational failures may reduce AWAC’s  
current earnings and distributions to Alumina Limited.
AWAC’s operations (particularly its mining operations) are  
subject to extensive permitting and approval requirements.  
These include permits and approvals issued by various 
government agencies and regulatory bodies at the federal,  
state, and local levels of governments in the countries in which  
we operate. The permitting and approval rules are complex,  
are often subject to interpretations by regulators, which may 
change over time, and may be impacted by heightened levels  
of regulatory oversight and stakeholder focus on addressing 
environmental and social impacts of mining activities. Changing 
expectations and increased information required by regulators 
could make AWAC’s ability to comply with the applicable 
requirements more difficult, inhibit or delay our ability to obtain 
the necessary approvals, if at all, result in approvals being 
conditioned in a manner that may restrict AWAC’s ability to 
efficiently and economically conduct its activities, require us to 
adjust our plans, or preclude the continuation of certain ongoing 
operations or the development of future operations. Failure to 
obtain, maintain, or renew permits or approvals, or permitting  
or approval delays, restrictions, or conditions may impact the 
availability and/or quality of the bauxite AWAC is able to mine  
and could increase AWAC’s costs, potentially having a materially 
adverse impact on AWAC operations and profitability.

Description
Response
Alumina Limited has representatives 
on AWAC boards, and has frequent 
briefings in respect of permits. 
AWAC entities, such as Alcoa of 
Australia, have meetings with relevant 
regulators to discuss mining permits.
Regulatory 
approvals and 
permits 
continued
In addition, the permitting processes, restrictions, and 
requirements imposed by conditional permits or approvals,  
and associated costs and liabilities, may be extensive and may 
delay or prevent commencing or continuing exploration or 
production operations, which could adversely affect AWAC’s 
mining operations and production, and consequently its refining 
operations, and could require it to curtail, close, or otherwise 
modify its production, operations, and sites.
Additionally, AWAC’s existing permits, approvals and licences may 
be rescinded or modified, or our mining plans may be adjusted, to 
mitigate against adverse impacts to sites within or near our mining 
areas that have environmental, biodiversity, or cultural significance, 
potentially having a materially adverse impact on AWAC 
operations and profitability. 
For example, Alcoa of Australia seeks annual approvals from  
the Western Australia government for rolling five-year mine plans  
to maintain operations at the Huntly and Willowdale bauxite mines. 
This statutory annual mine approvals process for Alcoa of Australia’s 
2023-2027 Mining and Management Program (MMP) took longer 
than it had taken historically due to increased requirements and 
expectations from stakeholders with respect to certain 
environmental matters. As a result of the prolonged approval 
process, Alcoa of Australia began mining lower grade bauxite  
in April 2023, which impacted Alcoa of Australia’s refineries by 
increasing the use of caustic, energy, and bauxite and decreasing 
alumina output. Alcoa of Australia’s 2023-2027 MMP was approved 
in December 2023, and in connection with such approval, Alcoa  
of Australia is subject to certain new requirements to address key 
environmental factors, such as enhanced protections for drinking 
water, increased distances from reservoirs, biodiversity, and 
accelerated forest rehabilitation. On 18 December 2023, the 
Western Australian Environmental Approval Authority (“EPA”) 
announced it is assessing the MMP. Separately, Alcoa of Australia 
has referred its next major mine move to Myara North and Holyoake 
to the EPA for assessment. Approvals are also required from the 
Commonwealth Department of Climate Change, Energy, the 
Environment and Water (“DCCEEW”). 
There remains a risk that future annual mine approvals, related 
forest clearing permits, EPA and/or DCCEEW and/or other 
required approvals will be delayed or conditioned (if obtained). 
Any such failure to obtain, maintain, or renew permits; restrictions 
or conditions imposed through the process or on approvals and 
permits obtained and/or ongoing delays in approval or permitting 
processes may further delay, impede or prevent commencing, 
continuing or expanding mining and/or refining operations and 
further impact the quality and/or availability of the bauxite AWAC 
is able to mine, potentially having a materially adverse impact  
on AWAC.

Joint venture
AWAC  
Structure
AWAC and Alumina Limited operate across a broad range  
of legal, regulatory, disclosure laws and political systems. The 
profitability of those operations may be adversely impacted by 
changes in the regulatory regimes. AWAC and Alumina Limited’s 
financial results could be affected by new or increasingly stringent 
laws, regulatory requirements or interpretations, or outcomes of 
significant legal proceedings or investigations adverse to AWAC  
or Alumina Limited. This may include a change in effective tax 
rates, additional tax liabilities or becoming subject to unexpected 
or rising costs associated with business operations or provision of 
health or welfare benefits to employees, regulations or policies.
AWAC and Alumina Limited are also subject to a variety of  
legal compliance risks. These risks include, among other things, 
potential claims relating to product liability, health and safety, 
environmental matters, intellectual property rights, government 
contracts, taxes and compliance with foreign export laws, anti-
bribery laws, competition laws and sales and trading practices. 
Failure to comply with the laws regulating AWAC’s businesses may 
result in sanctions, such as fines, additional tax liabilities or orders 
requiring positive action by AWAC, which may involve capital 
expenditure or the removal of licenses and/or the curtailment of 
operations. This relates particularly to environmental regulations.
Alumina Limited and AWAC 
undertake a variety of compliance 
training and governance functions  
to mitigate these risks.
Alcoa, on behalf of AWAC maintains 
policy and procedural documentation 
designed to comply with regulations, 
for example health and safety 
regulations, and environmental 
regulations.
Additionally, Alumina maintains  
a tax governance framework, and 
external tax advisors.
Material compliance matters are 
reviewed at the Strategic Council  
and other forums.
Refer to "Commitments and 
contingent liabilities for AWAC"  
on page 93.
AWAC’s shareholders, Alumina Limited and Alcoa, are different 
entities. Whilst Alumina Limited’s sole investment is in AWAC, 
Alcoa is invested in a broader range of activities, hence interests 
may not be aligned.
Alumina Limited does not hold a majority interest in AWAC, and 
decisions made by majority vote may not be in the best interests  
of Alumina Limited. Additionally, exclusivity provisions within the 
joint venture agreements may impede growth outside of the 
AWAC joint venture. 
There is also a risk that Alumina Limited and Alcoa may have 
differing priorities. 
During 2016, the joint venture 
agreements were modified to  
ensure that certain key decisions 
require Alumina Limited’s consent  
by a super-majority vote.

Alumina Limited regularly  
engages with Alcoa to understand 
future cash flow forecasts.
Alumina is required to fund its share of calls, subject to the 
provisions of the AWAC Agreements. If Alumina is unable or 
unwilling to fund its share of capital requirements, it may ultimately 
run the risk of its equity interest in AWAC being diluted according

Insufficient  
Cash  
Generation
There is a risk that as a result of a number of factors including  
high operating costs, higher than expected sustaining capital 
expenditure and/or low commodity prices, that AWAC may not 
generate sufficient cash flow to pay distributions to partners.
Sustainability
Environmental, 
Social, 
Governance 
(ESG)
AWAC operates facilities in several areas of the globe. AWAC’s 
facilities may be resource intensive, subject to regulatory and 
community standards, located in environmentally sensitive areas, 
and/or close to communities.
AWAC’s operations generate hazardous waste which are contained 
in tailing facilities, residue storage areas and other impoundments. 
Unanticipated structural failure or over-topping caused by extreme 
weather events could result in injury or loss of life, damage to the 
environment or property.
Failure to meet ESG regulations may result in material civil or 
criminal fines, penalties, loss or restrictions or conditions being 
imposed on licences and permits and curtailment or closure  
of facilities, or the loss of AWAC’s “social licence to operate”.
The social licence to operate (SLO) is an understanding/ 
perception of key stakeholders regarding the company’s  
activities and its delivery of key commitments on a range of  
issues (e.g. engagement with local communities including mutual 
benefits, protection of heritage areas, maintenance of biodiversity, 
interactions with indigenous peoples). Degradation of a SLO  
could eventually lead to the loss of an operational licence  
(or other penalties), and damage to reputation which could 
limit future prospects.
Alumina Limited regularly monitors 
AWAC’s cash cost and other 
measures such as cash cost.
Alcoa often executes programs of 
austerity to respond to downturns in 
economic cycles, which may involve 
rationalisation of the portfolio, 
delaying non-critical CAPEX or  
other cash saving measures.
AWAC has extensive policies and 
systems in respect of ESG matters. 
Additionally, Alcoa is a member of  
the International Council on Mining 
and Metals (ICMM), which is an 
organisation focused on enhancing 
mining’s contribution to society.
Alcoa has also rolled out its Social 
Management System (SMS, SP360)  
at all AWAC locations.
The SMS incorporates governance 
resources including corporate 
policies and standards, governing 
body oversight matched with defined 
procedures and assessments. The  
SMS includes the definition of 
performance metrics and long-term 
goals to be accomplished between 
2025 and 2030.
Alcoa reports instances of 
environmental non-compliance  
to Alumina Limited, and any 
appropriate response.
Alumina meets with Alcoa regularly  
to discuss material issues, and 
Alumina produces an annual 
Sustainability Update which involves 
the review of many key performance 
metrics in respect of ESG.
Climate  
change risk
Climate change is a systemic and material risk that will pose 
challenges in the future management of AWAC operations in 
regard to energy usage, GHG emissions, carbon pricing policies 
and regulations and market demand. Climate change results in  
a number of physical and transitional risks, which affect AWAC  
in the following manner.
Physical risks include:
Physical risks include increased risks to personnel, business 
continuity, production and facilities. Climate factors like extreme 
weather events are likely to have an impact on AWAC’s global 
mining and refining operations. This may include water stress, 
increased risks relating to residue disposal and production and/or 
supply chain risks from extreme weather events and changes in 
rainfall/sea levels.
Alumina LimitedAnnual Report 202329
Risk Title
Description
Response
A key mitigation against AWAC’s 
physical and transitional risks is to 
remain as low as possible on the 
refining cash cost and emissions 
intensity curves.
Additionally, Alumina Limited  
and Alcoa have both stated their 
ambitions to achieve “net zero” by 
2050 in respect of CO2e emissions.  
In order to do so, AWAC will need  
to identify alternate energy sources  
to displace the fossil fuels that it 
currently relies on, in particular  
for its refineries.
In respect of its refineries, AWAC  
is investing in R&D through its 
Refinery of the Future project to  
look for opportunities to electrify 
elements of a refinery, reduce energy 
or emissions, and utilise renewable 
electricity as opposed to the natural 
gas, coal and fuel oil that AWAC 
currently uses.
Investment in such technology  
is important to mitigate against 
physical and transitional risks. 
Potential Refinery of the Future 
technologies could help maintain 
AWAC’s low position on the emissions 
intensity curve means that AWAC’s 
products remain attractive to end 
users, reducing the risk of substitution  
to other metals, or the imposition  
of a material carbon price.
Climate  
change risk 
continued
Transitional risks include:
 · the increased scrutiny by governments on GHG emissions  
and the establishment of a carbon pricing, or other  
government regulation/intervention
 · substitution from one product to another
 · changes in consumer preferences, including consumer  
action/protest against a particular product
 · cost of emissions abatement and technology
 · rising cost, or availability of energy.
Energy is a significant input in a number of AWAC’s operations, 
making AWAC an emitter of greenhouse gases. The introduction  
of regulatory change by governments in response to greenhouse 
gas emissions (e.g. any potential changes to the Australian 
Government’s Safeguard Mechanism) may represent an increased 
cost to AWAC and may affect Alumina Limited’s profitability.
Technology risk exposure is the risk of substituting existing  
products and services with lower-emissions options. If AWAC is 
unable to remain low on the alumina GHG emissions curve, there is 
a risk that customers may choose alternate suppliers. Alternatively 
demand, and consequently the price of alumina may decrease. 
Though the Joint Venture is investing in technology to reduce the 
production of greenhouse gases in the manufacture of our products, 
such as the Refinery of the Future technologies that are designed  
to limit the production of carbon in alumina refining, in certain 
aspects of our operations, the Joint Venture's ability to reduce our 
GHG emissions is also dependent on the actions of third parties, 
especially energy providers, and the ability to make significant 
changes in AWAC's GHG emissions. As a result, AWAC could  
face additional costs associated with any new regulation of  
GHG emissions, and AWAC's ability to modify our operations  
to avoid these costs may be limited in the near term. 
Additionally, AWAC have established strategies and expectations 
relating to certain environmental, social, and governance 
considerations, including regarding reducing GHG emissions, 
reducing water usage, reducing waste, improving safety 
performance, and managing social risks across our operations. 
These strategies and expectations reflect our current plans and 
aspirations, and there is no guarantee that they will be achieved. 
AWAC's ability to achieve any such strategies or expectations  
is subject to numerous factors and conditions, some of which  
are outside of AWAC's control. Examples of such factors include,  
but are not limited to, evolving legal, regulatory, and other 
standards, processes, and assumptions, the pace of scientific and 
technological developments, increased costs, the availability of 
requisite suppliers, energy sources, or financing, and changes in 
carbon markets. Failures or delays (whether actual or perceived) in 
achieving our strategies or expectations related to climate change 
and other environmental matters could adversely expose us to 
potential liabilities, increased costs, reputational harm, and other 
adverse effects on our business, operations, and reputation, and 
increase the risk of litigation.
Market Risk exposure measures the changes in revenue mix  
and sources as a result of climate risk. AWAC’s customers may  
be exposed to industries that may be impacted by carbon prices.

Other risks
Closure/ 
impairment  
of assets
Financial 
management
Alumina Limited may be required to record impairment charges  
as a result of adverse developments in the recoverable values  
of its assets. To the extent that the carrying value of an asset  
is impaired, such impairment may negatively impact Alumina 
Limited’s profitability during the relevant period. 
Closure, curtailment or sale of any one of AWAC’s operations  
may result in a change in the timing or amount of required 
remediation activities (and corresponding cash flow) and/or  
an impairment being incurred as a result of the carrying value  
of an asset exceeding its recoverable value. Additionally, the 
conditions of rehabilitating closed assets may increase and the 
cost of closure may also increase over time. Alumina Limited  
does not have a contractual right in respect of the closure of 
loss-making assets, only a veto right in some circumstances. 
Alumina may be unable to access desired or required amounts  
of capital (either debt – including renewal of existing facilities or 
new financing, or equity at agreeable terms). Additionally, there  
is a risk that Alumina Limited’s credit rating may change which 
results in a moderate interest rate increase under existing 
arrangements and which could increase the cost/availability  
of future funding requirements.
Reliance on 
AWAC
Alumina Limited relies on information being provided by  
AWAC and Alcoa to inform its strategy and decision making  
and prepare its public disclosures. There is a risk of such 
information being delayed, incomplete or containing errors, 
leading to potential challenges in managing Alumina’s business 
and potential errors in Alumina’s public disclosures.
Closure of an asset may be  
necessary to ensure the ongoing 
competitiveness of AWAC operations.
Alumina Limited maintains capital 
management policies, regularly 
monitors commodity markets,  
actively manages its balance sheet, 
and also forecasts cash flow. 
Alumina Limited has a US$500 million 
syndicated bank facility with tranches 
maturing:
 · October 2025 (US$100 million)
 · January 2026 (US$150 million)
 · July 2026 (US$150 million)
 · June 2027 (US$100 million)
As at 31 December 2023 there was 
US$296.0 million drawn against the 
syndicated facility.
Alcoa maintains financial controls 
over the accounts of AWAC, which  
are also audited. An information

Whilst bauxite quality in WA is expected to remain 
similar to recent lower grades until bauxite can be 
accessed from new regions at Myara North and 
Holyoake (no earlier than 2027), the WA Government’s 
announcements provided increased confidence for  
the AWAC business in WA.
The Kwinana refinery was partly curtailed with one of 
the five digestors remaining offline since January 2023. 
In January 2024, plans for refinery’s full curtailment 
were announced.
During 2023 the San Ciprian refinery continued to 
operate at around 50% of capacity, after production 
was reduced in the second half of 2022. As announced 
in December 2023, discussions commenced on the 
future of San Ciprian refinery.
Production at the Alumar refinery was affected by  
a ship to-shore conveyance system failure, alumina 
ship loader maintenance as well as country wide  
power outages. 
Across the system there was increased planned  
and unplanned maintenance activity, carried out in  
line with the objective of improving system stability 
and operational performance. 
AWAC’s average realised price of $352 per tonne, was

In December 2023, the Western Australia Government 
approved AWAC’s latest five-year mine plan, known  
as the 2023-2027 Mining and Management Program 
(“MMP”), for its Huntly and Willowdale bauxite mines.  
In addition, the WA Government granted an exemption 
that allows AWAC to continue its mining operations 
whilst the WA Environmental Protection Authority 
undertakes a separate environmental impact 
assessment of the MMP.

The San Ciprian refinery benefiting from lower prices  
is the main driver for lower energy costs. Energy costs 
were also lower in Brazil due to favourable oil prices. 
This was offset by slightly higher energy costs in WA, 
mostly as a result of higher usage due to the processing 
of the lower bauxite grades.
European gas prices: MIBGAS (EUR/MWh)
The cash cost per bone dry tonne (BDT) of bauxite at 
AWAC operated mines remained stable at $12.9 per 
tonne. Bauxite cost per tonne of alumina in 2023 was 
marginally higher compared with 2022. Bauxite usage 
per tonne of alumina was higher as a result of the 
lower bauxite grades in WA, partly offset by reduced 
San Ciprian production where delivered bauxite costs 
are higher.

predominantly driven by a lower realised alumina price.
Third Party Bauxite Sales 
AWAC’s shipments to third party customers increased 
by 4.1 million BDT to 7.6 million BDT with the increase 
mainly from additional sales from CBG.
Third party revenue increased by 182% due to

Portland’s 2023 aluminium production was marginally lower compared to 2022. Production rates increased  
in the second half of 2022, running at about 95% of capacity following the restart of additional smelting pots.  
In March 2023 production rates were reduced to approximately 75% of capacity, due to operational instability  
and challenges related to production of rodded anodes. 
EBITDA was lower in 2023 compared to 2022, primarily as a result of lower aluminium prices. This was partially 
offset by a decrease in cash costs year on year supported by lower alumina prices.
In August 2023, Portland entered into a nine-year power supply agreement which will secure approximately  
50% of the energy required to meet smelter nameplate capacity. The agreement will take effect from 1 July 2026. 
4. AWAC Financial Review
AWAC recorded a net loss in the financial year ended 31 December 2023, reflecting lower average alumina and 
aluminium prices and higher cash costs of production, impacted by processing of the lower quality of bauxite 
grades in WA and higher maintenance cost in Brazil.
Income tax charge decreased in line with the lower taxable income generated by Australian and Brazilian 
operations, partially offset by the valuation allowance on deferred tax assets in Brazil.

The movement in the value of assets and liabilities includes the effect of the Australian dollar, Brazilian Real and 
Euro against the US dollar throughout 2023. 
Receivables increased due to the higher alumina realised prices in December 2023 relative to December 2022. 
Inventory decreased mainly as a result of lower volume of raw materials purchases due to decreased production 
levels and lower input prices, particularly for caustic soda.
Taxes payable and deferred decreased due to lower taxable income in Australia and the valuation allowance  
on deferred tax assets in Brazil.
Estimates for assets retirement obligations (“ARO”) related primarily to mine reclamation and closure of bauxite 
residue areas were increased with corresponding increase recorded in carrying amount of related long-lived 
assets (Property, plant and equipment).
Other liabilities increased due to higher accrued employee compensation and retirement costs as well as  
increase in current portion of AROs.

5. Alumina Limited Financial Review
Alumina Limited (“Alumina”) announced on 12 March 2024 that it has entered into a Scheme Implementation 
Deed with Alcoa Corporation (“Alcoa”) in relation to a proposal for Alcoa to acquire 100% of the fully paid 
ordinary shares in Alumina by way of a scheme of arrangement (“the Transaction”). Alumina Limited Annual Report 
for the year ended 31 December 2023 contains an Independent Auditor’s report which highlights the existence  
of a material uncertainty that may cast significant doubt about the Group’s ability to continue as a going concern  
if the Transaction with Alcoa completes and a Review Event under Alumina’s syndicated revolving cash advance 
facility agreement arises. Notwithstanding this, Alumina Limited Financial report for the year ended 31 December 
2023 have been prepared on a going concern basis, which assumes the Group will be able to realise its assets 
and discharge its liabilities in the normal course of business. For further information, refer to the section “About 
this Report” in the Notes to the consolidated financial statements, together with the auditor’s report.

Alumina Limited recorded a net loss after tax  
of $150.1 million (2022: net profit after tax of  
$104.0 million). 
Excluding significant items, net loss after tax  
would have been $91.9 million (2022: net profit  
after tax of $109.3 million).
The decline in the Company’s net profit is due to  
the decrease in the share of net profit of associates 
reflecting AWAC performance during 2023 relative  
to the previous year.
General and administrative expenses in 2023 
decreased due to the weaker Australian dollar, 
however, expenses expressed in AUD remained 
consistent with the previous year.
The Company’s finance costs in 2023 were higher 
than in the previous year, reflecting the higher  
debt level.

The increase in investments in associates was 
principally due to the net capital contributions made 
by Alumina Limited during the year and foreign 
currency revaluations.
Alumina Limited has a US$500 million syndicated bank 
facility with tranches maturing in October 2025 
(US$100 million), January 2026 (US$150 million), July 
2026 (US$150 million) and June 2027 (US$100 million). 
Alumina Limited’s net debt as at 31 December 2023 
was $294.3 million (2022: $106.2 million) and gearing 
was 17% (2022: 6.4%). 
As at 31 December 2023, there was US$296 million 
drawn against the syndicated facility (2022: US$110 
million).

Net contributions to AWAC totalled $159.1 million 
(2022: net receipts $166.5 million).
Additional capital contributions into AWAC were 
required to support working capital and capital 
expenditure needs of the AWAC entities. It is as a result 
of lower alumina realised prices and increased costs 
primarily due to the WA refineries operating with lower 
grade bauxite. 
Alumina Limited’s dividend policy is to distribute free 
cash flow derived from net AWAC distributions less the 
Company’s corporate and finance costs, whilst taking 
into consideration its capital structure, any capital 
requirements for AWAC and market conditions. 
The Board had considered the above factors and 
determined not to declare a final dividend in respect  
of the year ended 31 December 2023.

6. Market, Outlook and Guidance 
Alumina
Aluminium
Global primary aluminium consumption in 2023  
grew by 1.1%, mainly supported by China’s 4.9% 
growth in consumption. This was primarily driven by 
strong demand from solar panels and electric vehicles 
which more than offset weakness in China’s property 
sector. Demand in the rest of the world (“RoW”) 
dropped by 4.2% as it was impacted by high interest 
rates and stubborn inflation. Looking ahead to 2024, 
demand is expected to be supported by an improving 
macroeconomy and a shift back towards the metal 
intensive manufacturing sectors. The industrial 
destocking process which depressed demand for 
aluminium in 2023 is also expected to end in 2024. 
In the medium to longer term, global demand for 
aluminium is expected to be strong, underpinned  
by structural strength in China’s green economy and 
marked growth in renewable energy and electric 
vehicles. Over the next decade, global primary 
aluminium consumption is expected to grow by  
14% or about 10 million tonnes.
Primary aluminium production in the world excluding 
China was 29 million tonnes in 2023, representing an 
1.6% increase from the previous year. Production in 
RoW is expected to increase by about 2% over 2024.
LME aluminium prices peaked at around $2,600/t in 
January 2023 as improved sentiment from China’s 
post-covid reopening along with US dollar weakness 
both contributed to the rally. However, poorer than 
market anticipated demand quickly caused a 
retracement in price and the fear of widespread 
recession after central banks increased interest rates 
resulted in prices trading sideways for most of 2023. 
Low carbon aluminium premiums are developing and 
as decarbonisation trends advance, these premiums 
are expected to rise.
At the end of 2023, China’s primary aluminium capacity 
was estimated to be 44.8 million tonnes per annum, 
with a utilisation rate of 94%. New primary capacity 
rollout is forecast to be limited as China approaches 
the 45 million tonnes per annum cap. 
RoW metallurgical alumina production decreased  
by 1% in 2023, as supply disruptions in Australia, 
Europe and Brazil more than offset expansions in 
Indonesia and India. Non-metallurgical production of 
alumina in RoW contracted by 20% driven primarily by 
disruptions/curtailments in Europe and North America. 
The RoW metallurgical alumina market was tightly 
balanced in 2023, with a marginal deficit representing 
around 0.1% of the global supply. The Alumina Price 
Index spiked to a high of $371/t in February following 
the news of supply disruptions in Australia. Prices 
averaged $343/t for the year, a 5% decrease year  
on year and tracking with historical average. 
No new RoW greenfield metallurgical alumina projects 
are expected in 2024. Brownfield expansions and 
production ramp-ups are likely to be somewhat offset 
by supply disruptions in Australia. With steady demand 
growth from primary aluminium smelters, the RoW 
metallurgical alumina market in 2024 is forecast to  
be in further deficit compared to 2023. 
In China, metallurgical alumina production grew by  
5%, despite supply disruptions at inland refineries due 
to environmental audits and domestic bauxite supply 
concerns. This was driven by new projects and 
expansions at coastal refineries. 
China’s net alumina imports stood at 563 kt for 2023, 
down 44% from the year before. China is expected  
to produce alumina to only meet its internal demand  
and export excess tonnes to Russia. 
RoW refining costs averaged $288/t in 2023, down  
8% compared with 2022. This was driven primarily  
by easing of fuel and caustic costs. In China, average 
production costs also fell by 8% in 2023 to reach 
$320/t, driven by lower caustic soda and energy prices. 
Chinese refineries process lower quality domestic 
bauxite, and higher priced seaborne bauxite, which 
offset some of the cost savings. 
In China, alumina futures were introduced to the 
Shanghai Futures Exchange in June 2023, adding  
both liquidity and volatility to the Chinese market. 
Alumina LimitedAnnual Report 202341
In the Atlantic regions, notable transactions included 
Glencore’s acquisition of 30% equity stake of Alunorte 
refinery and Century’s acquisition of 55% share of 
Jamalco. Elsewhere, UC Rusal acquired 30% of Hebei 
Wenfeng New Materials in China, amounted to 1.4 Mt 
of alumina capacity per year. 
bauxite reserves deplete further both in volume and 
grades. Guinea is expected to be the main supplier  
of bauxite to China, followed by Australia. Despite a 
few bauxite beneficiation technologies being trialled  
in China, they have proven to be uneconomic or 
limited to only a small scale. 
Bauxite
The first half of 2023 saw the ban of Indonesian  
bauxite exports. Guinea more than compensated  
for Indonesia’s ban as China imported 99 Mt of 
Guinean bauxite in 2023, up 41% y/y. In 2023,  
Guinea accounted for 70% of China’s bauxite imports, 
compared with 56% in 2022. Total bauxite imports in 
China for 2023 stood at 142 Mt, representing a 13% 
increase y/y. This stems from both strict environmental 
policies and depleting bauxite reserve in China that 
necessitated the sourcing of seaborne bauxite. 
The surge in demand for Guinean bauxite led to  
an uptick in prices, with Guinea bauxite trading at 
$70.5/t on a CIF China basis at the end of 2023. This 
represents an increase of about $30/t since the start  
of 2021. In the near to medium term, China’s demand 
for imported bauxite is likely to grow as domestic 
In 2023, bauxite cost was around $167 per tonne of 
alumina in China, representing over 50% of refining 
costs. In contrast, RoW bauxite cost was around $76/t 
per tonne of alumina, or roughly 27% of refining costs. 
AWAC Guidance
The following 2024 guidance is provided to assist  
the understanding of the sensitivity of AWAC results  
to key external factors. The guidance cannot be 
expected to be predictive of exact results; rather it 
provides direction and approximate quantum of the 
impact on AWAC results. Sensitivity of each element  
of the guidance has been considered in isolation and 
no correlation with movements in other elements 
within the guidance has been made.

1.2. Remuneration in business context
Alumina Limited’s remuneration strategy and  
policy has been developed in recognition of the 
unique nature of the Company, the complexities  
of managing a significant but non-controlling  
interest in a global joint venture and the significance  
of external factors’ influence on the sector and the 
Company’s performance.
Alumina Limited owns a 40 per cent interest in the 
multibillion-dollar global enterprise, AWAC, one of  
the world’s largest bauxite and alumina producers. 
AWAC is a large capital intensive business operating  
in a number of jurisdictions with some in remote 
locations. Alumina Limited’s executives are responsible 
for protecting and advancing the interests of its 
approximately 52,000 shareholders in the management 
of AWAC. Consistent with the governing joint venture 
agreements, Alumina executives are responsible  
for providing strategic input and advice into the  
joint venture. 
This, in turn, draws on their abilities to persuade and 
influence our joint venture partner. To do so, they must 
have a clear position on the bauxite, alumina and 
aluminium markets to allow detailed and substantive 
discussion with our joint venture partner and our 
shareholders on portfolio management, investment 
opportunities, sustainability and disruptive threats.
At the Board’s direction, the CEO and key executives 
are required to aim to maintain Alumina Limited’s 
financial metrics consistent with an investment grade 
rating, maximise cash flow from AWAC and support  
the joint venture in its efforts to improve its relative  
cost position and strategic options.
Alumina Limited’s goal is to be an active, informed  
and engaged joint venture partner and therefore  
it requires and must retain, high calibre people  
with strong skills sets and commercial experience to  
ensure the Company and its investment are managed 
well. Hence, Alumina Limited’s remuneration needs  
to be competitive, valued and relevant.

CEO 
The design of the CEO’s remuneration package reflects 
the requirements of this critical leadership role to 
create long term shareholder value, the responsibility 
for the relationship with our joint venture partner and 
influence on the strategic direction of joint venture 
development and growth whilst advocating for the 
interests of shareholders.
The CEO’s remuneration package includes a restricted 
equity grant to better reflect the primarily influence-
based (rather than operational) nature of the role and 
align with Alumina Limited’s remuneration strategy. 
This design focuses on the value creation activities, 
whilst eliminating potential prioritisation of short-term 
goals over longer-term strategic objectives. It also 
ensures that through increased exposure to an 
equity-based component, the CEO’s remuneration 
reflects shareholders’ experience and is not excessively 
affected by swings in the commodity cycle.
The Board continues to set specific annual objectives 
for the CEO, some will relate to the year ahead, 
whereas others may take longer to achieve. 
Progress is reviewed formally quarterly and at the  
end of the year. This process provides the Board with  
a basis to assess and discuss CEO performance in the 
short term. Also, and importantly, it provides a basis  
to ensure that the Board and CEO are aligned on 
priorities that will underpin long-term shareholder 
value creation and go to the heart of the role as 
Alumina’s CEO.
It is Alumina’s philosophy to position the total CEO 
reward opportunity in the lower quartile of market peers 
(the ASX 51 – 100 and ASX 76 – 125 Rank comparator 
groups). These are the same peer groups that have 
been used to benchmark the CEO’s remuneration  
for a number of years. The Board considers these peers 
appropriate to set remuneration to attract and retain  
a CEO of appropriate skills and experience through 
the cycle. 
The CEO’s 2023 remuneration package was  
comprised of a FAR component of $1,488,400, an 
equity component delivered via Conditional Rights 
and Performance Rights equal to $489,300 and 
$621,000 respectively at the time of the grant. The 
actual remuneration awarded during the year is 
comprised of the same components, however their 
values will differ from the potential total remuneration, 
specifically in relation to the value of the equity 
components at the time of their vesting.

The actual remuneration received by CEO in 2023  
is comprised of a FAR component of $1,488,400,  
a Conditional Rights grant of $489,300 and zero 
Performance Rights at the time of testing and vesting 
under the 2021 LTI plan. 
The realised remuneration of the CEO remains strongly 
aligned to the shareholder experience. There has  
been no vesting of LTI grants in the past three years.
At the same time, the embedded value of the  
CEO’s existing share interests and Conditional Rights 
fluctuates in line with movements in Alumina Limited’s 
share price. The impact on the value of Conditional 
Rights granted to the CEO (and other KMPs) can be 
seen in the table below. 
The Company requires the CEO to build and maintain 
a holding of Alumina Limited’s securities equal  
to 100% of his fixed remuneration. Mr Ferraro has  
not sold any shares acquired on vesting of rights 
(Conditional or Performance) since his appointment  
as CEO in 2017.
For the 2024 remuneration, the Board has considered 
the market outlook, inflation rate and changes in 
superannuation guarantee contribution rates and 
resolved to award a 4% increase of the CEO’s total 
reward opportunity by equally increasing each of the 
remuneration components – FAR, Conditional Rights 
and LTI. The CEO’s total remuneration remains in  
the bottom quartile of the ASX 76-125 based on 
benchmarking data.

1. The number of CEO’s Conditional Rights is determined by dividing the set value of $489,300 (2022: $472,800) by a VWAP of $1.53 (2022: 
$1.90). 2. The number of CFO’s Conditional Rights is determined by dividing the set value of $90,000 (2022: $75,000) by VWAP of $1.53 
(2022: $1.90). 3. The value of Conditional Rights vested is determined by the number of vested Rights multiplied by the market price at the 
vesting date. 4. The value of Conditional Rights as at 31 December 2023 is determined by the number of vested Rights multiplied by the 
market price at that date. 5. Mr Foster retired on 1 July 2023. The number of Conditional Rights granted was determined by dividing the set 
value of $146,000 by VWAP of $1.53 and pro-rated for the period of service. The value vested is determined using the share price of $1.38  
on 30 June 2023. Given that Mr Foster ceased to be a KMP during the year, his vested Conditional Rights as at 31 December 2023 are not 
disclosed. Refer section 4.5 for details on the cessation of employment.
Alumina LimitedAnnual Report 20232. Company performance and  
executive remuneration outcomes
2.1. Company performance
Alumina Limited recorded a net loss after tax of  
$150.1 million dollars. The Company did not declare 
dividends for the year ended 31 December 2023.
In 2023, AWAC experienced delays with approvals for 
bauxite mining in Western Australia, which negatively 
affected production from the Australian refineries and 
the overall alumina production costs at the combined 
AWAC Level. The Kwinana refinery was partly curtailed 
from January 2023 and in January 2024 plans for  
the full curtailment of the refinery were announced, 
beginning in the second quarter of 2024. 
Production from other AWAC operated refineries 
decreased too. The San Ciprian refinery continued  
to operate at around 50% of its capacity and the 
Alumar refinery was affected by the maintenance 
events related to the ship-to-shore conveyance system 
failure and alumina ship loader. As announced in 
December 2023, engagement with the stakeholders  
in Spain was initiated in relation to the future of the  
San Ciprian operations. Overall, across the business 
production of alumina decreased by 12.5% in 2023.
The realised alumina price in 2023 was $352 per 
tonne, 5.1% down compared to the prior year.  
At the same time, AWAC’s production costs increased 
to $308 per tonne due to lower bauxite grades used 
by the Pinjarra and Kwinana refineries as well as costs 
associated with the unplanned maintenance events in 
Brazil. As a consequence, AWAC’s margin decreased, 
year on year to $44 per tonne. For the year ended  
31 December 2023, AWAC recorded a net loss after 
tax of $317.8 million and its EBITDA has decreased  
to $164.5 million.
49
In the context of the regulatory and operating 
challenges faced by the AWAC during the last year, 
Alumina Limited’s share price declined in the second 
half of 2023. However, the AWC share price has 
remained highly correlated to the price of alumina 
through the commodity cycle:

2023 outcomes
Fixed  
remuneration
Deferred equity 
remuneration1 
Long-term  
incentive
With consideration to the market outlook, inflation factors and changes in the 
superannuation guarantee contribution rates, the CEO’s total reward in 2023 was 
increased by 3.5% by equally increasing each of the remuneration components,  
being FAR, Conditional Rights and LTI. 
In 2023, fixed remuneration for Ms Kraeva and Mr Foster increased by 4.2% and  
3.5% respectively.
From 2024, fixed remuneration for the CEO increased by 4%, in line with the increases 
applied to the broader staff of the Company. CFO fixed remuneration increased by 
10.5% to $690,600 to address the market competitiveness of her fixed remuneration.
The annual deferred equity grant was made to key executives. In the case of  
the Company Secretary, his outcome was pro-rated for the part of the year he  
was employed.
The FY21 LTI was tested in 2023 (testing period December 2020 to December 2023) 
and Alumina Limited’s performance against the ASX and International Comparator 
Groups fell below the minimum required vesting threshold of 50th percentile ranking 
and therefore zero per cent of the potential entitlement vested. 
This outcome reflects the shareholder experience during the testing period and 
illustrates the LTI functioning as intended.
1. The Board evaluates performance of the CEO and CFO against a range of individual and non-financial objectives. Performance as having 
met expectations has been taken into account in setting up the level of remuneration for 2024.

2.3 Actual “take home” 2023 remuneration  
of continuing1 Executive KMP
The information below includes the actual ‘take home’ 
remuneration for continuing executives and does  
not include each Executive KMP from the statutory 
remuneration table (See section 2.5 on page 56). 
 · Conditional Rights vested (being the number  
of Conditional Rights that vested multiplied  
by the market price at the vesting date); and
 · LTI vested and exercised (being the number of 
Performance Rights that vested and exercised 
multiplied by the market price at the exercise date).
The actual remuneration awarded during the year 
comprises the following elements:
 · Cash salary including superannuation benefits,  
leave entitlements and any salary sacrifice 
arrangements and other agreed annual cash 
payments, but excluding termination payments;
 · Other short-term benefits comprised of the personal 
financial advice allowance and travel allowance;
These values differ from the executive statutory 
remuneration table and have not been prepared in 
accordance with statutory requirements and Australian 
Accounting Standards. The directors believe that the 
‘take home’ remuneration is more relevant to users  
as the statutory remuneration shows benefits before 
they are received by executives, even though certain 
benefits, such as LTI awards, may fail to vest.

2.4 Executive KMP performance under the LTI plan
2023
Key features of the LTI Plan
Description
The LTI is delivered in the form of Performance Rights that are tested over a three-year 
performance period. Each Performance Right that vests delivers to the holder an ordinary 
share in Alumina Limited upon exercise of the Right.
Performance  
period
Performance  
hurdles
Three years
Alumina Limited’s performance is tested using relative TSR compared against two  
comparator groups. Relative TSR was chosen as an appropriate means of measuring  
Company performance as it incorporates both capital growth and dividends.
The two comparator groups against which Alumina Limited’s performance were tested are:
 · ASX Comparator Group (Test 1 – 50% weighting): Australian listed entities in S&P/ASX 100 
Index, excluding property trusts, the top 20 companies by market capitalisation and  
Alumina Limited.
 · International Comparator Group (Test 2 – 50% weighting): reflecting the Company’s direct 
competitors in the market comprising nine selected companies in the alumina and/or 
aluminium industries that are listed in Australia or overseas, excluding the Company. The 
following companies were included in the group: Alcoa Corporation, Aluminium Corporation 
of China, Century Aluminium Company, Hidalco Industries, Norsk Hydro ASA, Shandong 
Nanshan Aluminium Co., South32, United Company Rusal (HKG) and Yunnan Aluminium Co. 
Performance  
assessment
Performance hurdles are independently measured by Deloitte Financial Advisory at the 
conclusion of the relevant performance period. Alumina Limited’s TSR is ranked against the 
TSR of companies in each of the comparator groups.

Following testing, any Performance Rights that have not vested will lapse.
The participant is only entitled to proportionally receive dividends and other distributions,  
bonus issues or other benefits if the performance conditions applicable to Performance  
Rights are satisfied (or waived) and the Performance Rights vest and are exercised.
Shares relating to Performance Rights, are not automatically allocated upon vesting. Instead, 
participants are entitled to exercise each relevant Performance Right at any time during the 
applicable exercise period (Exercise Period) after vesting. The Exercise Period will generally  
end seven years after vesting of the relevant Performance Rights. However, the Exercise Period 
may be shortened in certain circumstances such as cessation of employment or a change of 
control event. Performance Rights that do not vest as at the end of the vesting period will lapse.
In 2023 the Board exercised its discretion to determine, that upon key management personnel 
(KMP), including Mr Ferraro, ceasing employment with the Company as a result of genuine 
retirement (and being considered a good leaver under the ESP rules), the ESP rule providing for 
pro rata lapsing should not apply to all of the relevant KMP member’s unvested Performance 
Rights that existed as at 31 December 2023. The Board exercised its discretion to encourage 
retention of KMP and having regard to the Company’s best interests. This exercise of discretion 
does not apply to future Performance Rights that are issued such as those offered in January 
2024. However, the Board could in the future determine to exercise that discretion for the 
Performance Rights offered in January 2024.

1. If the Company’s TSR performance is equal to that of any entity (or security) between the 50th percentile and the 75th percentile of the 
International Comparator Group ranked by TSR performance, the number of Performance Rights in the relevant half of the LTI award that vest 
will be equal to the vesting percentage assigned by the Board to that entity (or security). If the Company’s TSR performance is between that  
of any two such entities (or securities) in the International Comparator Group, the number of Performance Rights in the relevant half of the LTI 
award that vest will be determined on a pro rata basis relative to the vesting percentages assigned by the Board to those entities (or securities). 
2. To determine the number of Performance Rights to be offered, the LTI opportunity is allocated using a face value allocation methodology 
being the annual dollar value of the LTI grant divided by the average Company share price over the 20 trading days leading up to the time that 
the Board determined to make offers of Performance Rights under the LTI plan for the relevant year. 3. The former Company Secretary/General 
Counsel had an LTI opportunity equal to 40% of his fixed annual remuneration. He retired on 1 July 2023.
Alumina Limited’s performance resulted in zero per cent of the total potential entitlement in relation to the FY21 
LTI vesting in December 2023. The table below summarises Alumina Limited’s TSR performance against each of 
the comparator groups. Full reconciliation of number of rights at the beginning and the end of the financial year 
provided in section 4.2 of this report.

3. Non-Executive Directors remuneration
3.1 2023 Non-Executive Directors  
remuneration
The maximum remuneration for Non-Executive 
Directors is determined by resolution of shareholders. 
At the 2023 AGM, shareholders approved a maximum 
aggregate remuneration of $1,700,000 per annum  
for Non-Executive Directors. A total of $1,171,026 
(inclusive of superannuation) was paid in Non-
Executive Director fees in 2023.
Other than the Chairman, who receives a single  
base fee of $410,000 (inclusive superannuation), 
Non-Executive Directors receive a base fee plus 
additional fees for membership of Board Committees 
and superannuation contribution (the exception being 
Mr Chen Zeng, who has elected to forgo all Board fees 
effective from 1 July 2023). Non-Executive Directors  
do not participate in incentive plans or receive any 
retirement benefits other than statutory 
superannuation contributions.
The remuneration packages for Non-Executive 
Directors are set out below. Superannuation 
contributions made by the Company on behalf  
of Non-Executive Directors are included in the  
fees amounts presented in the table on the right. 
There will be no increase in the Non-Executive 
Directors fee pool, base fee, member fee or committee 
chair fee (other than the Sustainability Committee 
Chair fee) in 2024. The Sustainability Committee  
Chair fee in 2024 will be $38,325. From 1 July 2024, 
the SGC rate will rise to 11.5%, director fees will not 
be changed as a result of the rate increase. 
All Non-Executive Directors enter into a service 
agreement with the company in the form of a letter  
of appointment. The letter summarises the board 
policies and terms, including remuneration, relevant  
to the office of director. The table below provides 
summary of the actual remuneration received by  
each Non-Executive Director and is prepared in 
accordance with statutory requirements and  
relevant accounting standards.

3.2 Non-Executive Directors share holdings
Each Non-Executive Director is required to hold shares in the Company having a value at least equal to 50 per 
cent of their annual fees (based on the date of purchase of shares) within five years from their appointment as a 
Director. Provided the minimum shareholding requirement is satisfied when shares are acquired or by the expiry 
of the five year term, should a decline in the Company’s share price mean the value of the shareholding does not 
equal 50% of the amount of base annual fees, directors are not required to acquire shares to increase their level  
of shareholding to equal the amount of 50% of the base annual fees. 
Subject to the Company’s Securities Dealing Policy, it is the Director’s decision at what time the required 
shareholding is acquired.

1. Mr Ferraro receives Conditional Rights as an element of remuneration. 2023 includes Conditional Rights granted on 12 January 2023  
(2022: 3 February 2022). The number of Conditional Rights is determined by dividing the set value of $489,300 (2022: $472,800) by a Volume 
Weighted Average Price (VWAP) of $1.53 (2022: $1.90). 2. Ms Kraeva receives Conditional Rights as an element of remuneration. Conditional 
Rights were granted on 12 January 2023 (2022: 3 February 2022). The number of Conditional Rights is determined by dividing the set value 
of $90,000 (2022: $75,000) by a VWAP of $1.53 (2022: $1.90). 3. Conditional Rights to Mr Foster were granted on 12 January 2023.The 
number of Conditional Rights was determined by dividing the set value of $146,000 by a VWAP of $1.53. 4. On vesting, each Conditional 
Right automatically converts into an ordinary share in Alumina Limited. The terms of Conditional Rights granted were not altered during 
2023. The number of Conditional Rights vested is the number granted in the prior years, following the completion of the required service 
period. There is a three-year trading restriction on the shares from grant date as long as Executive KMP remain employed by the Company. 
5. Mr Foster retired on 1 July 2023 and received a pro-rata allocation of Conditional Rights for the period of employment. The remaining 
rights have lapsed. 6. Number of Conditional Rights yet to meet the required condition and have not lapsed. 7. Value vested is equal to the 
number of Conditional Rights that have satisfied the required conditions multiplied by the share price at the time of vesting. In 2023, for  
Mr Ferraro, it was 248,843 Conditional Rights by the share price of $1.71 on 3 February 2023 (2022: 256,957 Conditional Rights by the share 
price of $2.05 on 14 January 2022). For Ms Kraeva, it was 39,474 Conditional Rights by the share price of $1.71 on 3 February 2022. For  
Mr Foster, the value vested is determined using the share price of $1.38 on 1 July 2023. 8. The maximum value of the Conditional Rights is 
based on the number of rights that vest and are released at the expiration of the conditional period, multiplied by the share price on the  
date of release. 9. The value of the equity remains subject to performance of the Company’s share price.

1. 2023 include Performance Rights granted on 19 January 2023 (2022: 3 February 2022) for the three-year performance test period concluding  
7 December 2025 (2022: 9 December 2024). The award of performance rights to the CEO was approved by shareholders at the AGM on  
29 May 2023 (2022: 25 May 2022). 2. Includes the number of Performance Rights granted that were subject to testing in 2023. 3. The terms of 
Performance Rights granted were not altered during 2023. Number of Performance Rights granted calculated as the annual dollar value of the  
LTI grant divided by the average Company share price over the 20 trading days leading up to the time that the Board determined to make offers 
under the LTI plan for the relevant year. 4. 2023 include the number of Performance Rights that, due to testing of the relevant period, were vested 
and exercised in 2023. It also includes Performance Rights vested in previous years that were exercised in 2023. 5. Performance Rights vest on 
satisfaction of the performance criteria. The eligible participant then enters an exercise period that concludes at 5:00pm (Melbourne time) on the 
date that is seven years after vesting. Vested ESP entitlements that are not exercised by the end of the Exercise Period will lapse (and consequently 
no Shares will be allocated, and no Cash Settlement Amounts will be paid, in respect of those vested ESP entitlements). However, if any of eligible 
participants vested ESP entitlements would otherwise lapse at the end of the Exercise Period because of this rule, and they have not previously 
notified Alumina Limited that they do not wish those vested ESP entitlements to be exercised, then they will be deemed to be exercised by the 
eligible participant. 6. The number of the Performance Rights that did not meet the criteria for vesting and therefore lapsed. As disclosed in 
section 2.4, zero per cent of Performance Rights vested in 2023 due to testing of Tranche 21. 7. Includes number of Performance Rights granted 
subject to future testing (yet to vest) and number of Performance Rights vested but yet to be exercised. 8. Mr Foster’s unvested Performance 
Rights lapsed proportional to the amount of the testing period that had not yet elapsed at the time of retirement. More detail on his unvested 
Performance Rights is included in section 4.5 of this Report. Since Mr Foster is no longer employed by the Company, the number of his 
performance rights at year end is not disclosed. 9. Mr Wood ceased to be a KMP on 30 September 2022.

1. Calculated by multiplying the number of Performance Rights granted by the fair value as at the date of the grant, independently calculated 
by Deloitte Financial Advisory (2022: Mercer Consulting (Australia)), using the assumptions underlying the Black-Scholes methodology to 
produce a Monte Carlo simulation model that accommodates features associated with Alumina Limited’s ESP such as exercise, lapse and 
performance hurdles. 2. The value of Performance Rights exercised is determined by the number of Rights multiplied by the market price  
at the exercise date. 3. The minimum value of the Performance Rights for any given year is zero.

1. Number of shares held at 1 January and 31 December of the respective years include directly held, and nominally held shares, and shares

as ICFO/CFO. 2. December 2023 testing of 2021 Performance Rights resulted in zero per cent vesting of total potential entitlement. In 2022, 
2020 Performance Rights that were tested in December 2022 resulted in zero percent vesting. 3. Mr Foster retired during the year and 
therefore his shareholding as at 31 December 2023 was not disclosed.

Term of agreement  
and notice period
Mike Ferraro

some or all of the notice period.
 · Any payment to be made to Mr Ferraro in lieu of notice shall be 
calculated based on his Fixed Annual Reward. He would also receive  
any statutory entitlements.
 · Number of shares equal to the granted Conditional Rights that would 
have vested during notice period.
 · In addition to the above, Mr Ferraro may terminate his employment by 
giving notice to Alumina Limited (effective immediately or up to six 
months later) in the event of a Significant Change. In that case Mr Ferraro 
will be entitled to receive a payment equal to 12 months’ Fixed Annual

He will also be entitled to payment in lieu of accrued annual and long 
service leave entitlements.

executive). Calculated according to the “Base Remuneration”, which is defined as FAR for Mr Ferraro and Ms Kraeva; and FAR + STI at target  
for Mr Foster. The above termination entitlements are subject to any restrictions imposed by the Corporations Act 2001.
Alumina LimitedAnnual Report 202365
4.5 Cessation of employment
4.7 Clawback policy
Mr Foster retired from the position of the Company 
Secretary on 1 July 2023. In accordance with the terms 
of his employment contract, on departure, Mr Foster 
was paid FAR of $296,400, a pro rata amount of his 
FY23 STI of $66,365 assessed at the time of his 
retirement and compensation for unused annual and 
long service leave of $225,346. Mr Foster also received 
Conditional Rights issued for the amount of $73,000. 
Prior to cessation of employment, Mr Foster had three 
tranches of Performance Rights due for testing in 
December 2023, 2024 and 2025, in total 414,000 
Performance Rights. 
In general and subject to Board discretion, where an 
executive ceases employment during the performance 
period as a good leaver any unvested incentives will 
be pro-rated to time and left-on foot to be tested in 
accordance with the original terms of the LTI. 
In 2022, the Board determined that, upon cessation  
of employment with the Company as a result of 
genuine retirement by KMP and being a ‘good leaver’, 
unvested Performance Rights would remain on foot  
to be tested and vest in the ordinary course of the  
plan. Mr Foster’s unvested incentives were treated  
as follows:
Alumina Limited has a Clawback Policy that provides 
scope for the Board to recoup incentive remuneration 
paid to the CEO and senior executives where:
 · material misrepresentation or material restatement  
of Alumina Limited’s financial statements occurred  
as a result of fraud or misconduct by the CEO or any 
senior executives; and 
 · the CEO or senior executives received incentive 
remuneration in excess of that which should have 
been received if the Alumina Limited financial 
statements had been correctly reported.
The Board also may seek to recover gains from the  
sale or disposition of vested shares and determine  
to cancel unvested equity awards.
4.8 Share trading and hedge prohibition
Conditional Rights granted to Executive KMP and 
Performance Rights granted under Alumina Limited’s 
LTI plan must remain at risk until fully vested. This is 
consistent with Alumina Limited’s Share Trading  
Policy that prohibits Directors and employees from 
engaging in:
 · short-term trading of any Alumina Limited securities
 · The 2021 Performance Rights were tested in 
December 2023 and resulted in zero percent vesting
 · buying or selling Alumina Limited securities if they 
possess unpublished, price-sensitive information; or
 · The 2022 Performance Rights are retained  
subject to future testing
 · The 2023 Performance Rights are retained on  
a pro-rata basis, with 29,772 rights retained and 
128,628 rights lapsed (on the basis he was only 
employed for 6 months of the relevant  
performance period). 
4.6 Change of control
In the event of a change in control, the Board  
may bring forward the testing date for the LTI 
performance conditions, or waive those conditions, 
and/or shorten the exercise period for Performance 
Rights that have already vested or that vest 
subsequently. The Board may also, in its discretion, 
determine that cash settlement amounts will be  
paid in respect of any vested Performance Rights.1
 · trading in derivative products over the Company’s 
securities, or entering into transactions in products 
that limit the economic risk of their security holdings 
in the Company.
This report is made in accordance with a resolution  
of the Directors.
W Peter Day  
Chairman
26 March 2024
1. In relation to the CEO,  where a change of control occurs, the performance conditions for unvested Performance Rights will be 
automatically waived and the Performance Rights will therefore vest, unless the Board determines otherwise. The Board may also shorten 
the Exercise Period for Performance Rights that vest or have already vested.

Alumina LimitedAnnual Report 202371
NOTES TO THE CONSOLIDATED  
FINANCIAL STATEMENTS FOR THE  
YEAR ENDED 31 DECEMBER 2023 
About this report
Alumina Limited is a for profit company limited by 
shares incorporated and domiciled in Australia whose 
shares are publicly traded on the Australian Securities 
Exchange. The consolidated financial report of the 
Group for the year ended 31 December 2023 was 
authorised for issue in accordance with a resolution  
of the Directors on 26 March 2024.
The consolidated financial report is a general  
purpose financial report which:
 · incorporates assets, liabilities and results of 
operations of all Alumina Limited’s subsidiaries  
and equity accounts its associates. For the list of  
the Company’s associates and subsidiaries refer 
Notes 2(a) and 3 respectively.
 · has been prepared in accordance with the 
requirements of the Corporations Act 2001, 
Australian Accounting Standards (AAS) and 
Interpretations issued by the Australian Accounting 
Standards Board (AASB). Alumina Limited is a  
for profit entity for the purpose of preparing the  
financial statements.
 · complies with International Financial Reporting 
Standards (IFRS) as issued by the International 
Accounting Standards Board.
 · has been prepared under the historical cost 
convention, as modified by the revaluation of certain 
financial assets and liabilities (including derivative 
instruments) at fair value through profit or loss.
 · the Company is of a kind referred to in the Australian 
Securities and Investments Commission Corporations 
Instrument 2016/191, relating to the “rounding off” 
of amounts in the financial report. Amounts in the 
financial report have been rounded off in accordance 
with that Legislative Instrument to the nearest 
hundred thousand dollars, and presented in US 
dollars, except where otherwise required.
 · adopts all new and amended Accounting Standards 
and Interpretations issued by the AASB that are 
effective for the annual reporting period beginning  
1 January 2023.
 · does not early adopt Accounting Standards and 
Interpretations that have been issued or amended 
but are not yet effective.
 · presents reclassified comparative information  
where required for consistency with the current  
year’s presentation.
Basis of preparation – going concern
These financial statements have been prepared on a 
going concern basis, which assumes the Group will be 
able to realise its assets and discharge its liabilities in 
the normal course of business.
As outlined in note 15, Alumina Limited (“Alumina”) 
announced on 12 March 2024 that it has entered into a 
Scheme Implementation Deed with Alcoa Corporation 
(“Alcoa”) in relation to a proposal for Alcoa to acquire 
100% of the fully paid ordinary shares in Alumina by 
way of a scheme of arrangement (“the Transaction”).  
In the event that the Transaction proceeds with the 
required approvals, Alumina would form part of Alcoa 
and future decisions in relation to the Group's ongoing 
operations and financing would be the responsibility 
of Alcoa. As is typical for transactions of this nature, 
completion of the Transaction will give rise to a Review 
Event under Alumina’s syndicated revolving cash 
advance facility agreement (“Facility”).
Should a Review Event arise Alumina may be required 
by the lenders to repay without penalty (other than 
Break Costs) all outstanding loans together with accrued 
interest and other amounts within 90 business days.
As a result of these matters, there is a material 
uncertainty that may cast significant doubt on the 
Group’s ability to continue as a going concern and, 
therefore, that it may be unable to realise its assets and 
discharge its liabilities in the normal course of business. 
Notwithstanding the paragraph above, the Transaction 
is not subject to any financing conditions and Alumina 
expects that Alcoa will address the Review Event  
in the course of implementation of the Transaction,  
which may include through a refinancing with the 
lenders or repayment under the facility, as is customary 
for transactions of this nature.  Accordingly, Directors 
have determined that the financial reports should  
be prepared on a going concern basis.

The notes to the financial statements
Foreign currency translation
The notes include information which is required to 
understand the financial statements and is material  
and relevant to the operations, financial position and 
performance of the Group. Information is considered 
material and relevant if, for example:
 · the amount in question is significant because  
of its size or nature,
 · it is important for the understanding of the  
results of the Group, or
 · it relates to an aspect of the Group’s operations  
that is important to its future performance.
The notes are organised into the following sections:
 · Group structure and Alcoa World Alumina and 
Chemicals (“AWAC”) performance: explains the 
group structure and information about AWAC’s 
financial position and performance and its impact  
on the Group.
 · Financial and capital risk: provides information  
about the Group’s financial assets and liabilities  
and discusses the Group’s exposure to various 
financial risks and explains how these affect the 
Group’s financial position and performance and  
what the Group does to manage these risks.  
It also describes capital management objectives  
and practices of the Group.
 · Key numbers: provides a breakdown of individual 
line items in the financial statements that the 
Directors consider most relevant and summarises  
the accounting policies, judgements and estimates 
relevant to understanding these line items.
 · Additional disclosures: provides information  
on items, which require disclosure to comply  
with Australian Accounting Standards and other 
regulatory pronouncements. However, they  
are not considered critical in understanding the 
financial performance of the Group and are not 
immediately related to the individual line items  
in the financial statements.
Accounting policies, critical accounting 
estimates and judgements
Significant and other accounting policies that 
summarise the measurement basis used and are 
relevant to the understanding of the financial 
statements, as well as critical accounting estimates  
and judgements are provided throughout the notes  
to the financial statements.
The consolidated financial statements are presented  
in US dollars, which is Alumina Limited’s presentation 
and functional currency. 
Foreign currency transactions are translated into the 
functional currency using the exchange rates prevailing 
at the dates of these transactions. Foreign exchange 
gains and losses resulting from the settlement of such 
transactions and from the translation at year-end 
exchange rates of monetary assets and liabilities 
denominated in foreign currencies are recognised  
in the profit or loss, except when they are deferred  
in other equity as qualifying cash flow hedges and 
qualifying net investment hedges or are attributable  
to part of the net investment in a foreign operation.
The results and financial position of the Group entities 
and associates that have a functional currency different 
from the presentation currency are translated into the 
presentation currency as follows:
 · assets and liabilities for each balance sheet 
presented are translated at the closing rate  
at the date of that balance sheet.
 · income and expenses are translated at average 
exchange rates (unless this is not a reasonable 
approximation of the cumulative effect of the rates 
prevailing on the transaction dates, in which case 
income and expenses are translated at the dates  
of the transactions). 
 · all resulting exchange differences are recognised  
in other comprehensive income.
 · on consolidation, exchange differences arising  
from the translation of any net investment in foreign 
entities, and of borrowings and other financial 
instruments designated as hedges of such 
investments, are recognised in other comprehensive 
income. When a foreign operation is sold, its share 
of such exchange differences is reclassified to the 
profit or loss, as part of the gain or loss on sale. 
Group structure and AWAC performance
1. SEGMENT INFORMATION 
Alumina Limited’s sole business undertaking is in  
the global bauxite, alumina and aluminium industry, 
which it conducts primarily through bauxite mining  
and alumina refining. All of those business activities  
are conducted through its 40% investments in AWAC. 
Alumina Limited’s equity interest in AWAC forms  
one reportable segment. A full description of

Notes to the Consolidated Financial Statements for the year ended 31 December 202374
2. INVESTMENT IN ASSOCIATES (continued)
The audited combined financial statements of the 
entities forming AWAC are prepared in accordance 
with Accounting Principles Generally Accepted in  
the United States of America (US GAAP). Alcoa of 
Australia Limited (AWAC entity) further issues audited 
financial statements prepared in accordance with the 
requirements of the Corporations Act 2001, Australian 
Accounting Standards (AAS) and interpretations issued 
by Australian Accounting Standards Board.
For the remaining AWAC entities, adjustments  
are made to convert the accounting policies under  
US GAAP to AAS. The principal adjustments are  
to create an additional asset retirement obligation  
for dismantling, removal and restoration of certain  
refineries, differences in the recognition of actuarial 
gains and losses on certain defined pension plans  
and the reversal of certain fixed asset uplifts included 
in Alcoa World Alumina Brasil Ltda.
In arriving at the value of these GAAP adjustments, 
Management is required to use accounting estimates 
and exercise judgement in applying the Group’s 
accounting policies. The note below provides an 
overview of the areas that involved a higher degree  
of judgement or complexity.
b) Critical accounting estimates  
and judgements
Estimates and judgements are continually evaluated 
and are based on historical experience and other 
factors, including expectations of future events that 
may have a financial impact on the Group and that are 
believed to be reasonable under the circumstances. 
The resulting accounting estimates will by definition, 
seldom equal the related actual results. The estimates 
and judgements that have a significant risk of causing 
a material adjustment to the carrying amounts of  
assets and liabilities within the next financial year  
are disclosed below.
Retirement benefit obligations
The Group recognises a net liability for retirement 
benefit obligations under the defined benefit 
superannuation arrangements through its investment  
in AWAC. All plans are valued in accordance with  
AASB 119 Employee Benefits. These valuations require 
actuarial assumptions to be made. All re-measurements 
are recognised in other comprehensive income.
Asset retirement obligations
The estimated costs of rehabilitating mined areas and 
restoring operating sites are reviewed annually and 
fully provided at the present value. The amount of 
obligations recognised under US GAAP by AWAC is 
adjusted to be in compliance with AAS. This requires 
judgemental assumptions regarding the reclamation 
activities, plant and site closure and discount rates to 
determine the present value of these cash flows.
Carrying value of investments in associates
The Group assesses at each reporting period whether 
there is objective evidence that the investment in 
associates might be impaired by:
 · Reviewing whether there are any potential indicators 
of impairment such as a significant decline in the 
market capitalisation, significant deterioration in 
expected future commodity prices, any material 
increases in production costs, adverse movements  
in exchange rates, production cut backs, increases in 
interest rates that might affect the discount rate used 
in calculating the recoverable amount and some 
others. The effect of climate related risks and 
opportunities is also considered when performing  
a test for impairment indicators;
 · If indicators of impairment exist, calculating the 
recoverable amount of the investment in AWAC 
using a value in use model (“VIU model”). VIU value  
is determined by using a discounted cash flow 
method; and
 · Comparing the resulting value to the carrying value.
The key assumptions used in the VIU model to  
estimate future cash flows are those relating to future 
alumina and aluminium prices, exchange rates, energy 
prices and other input prices. Key assumptions are 
determined with reference to industry participants  
and brokers’ forecasts, commodity and currency 
forward curves and industry consultant views. 
These assumptions are used to estimate future  
cash flows in the VIU model. The estimated cash  
flows are then discounted to net present value  
using the weighted average cost of capital (WACC)  
of 10.0% (2022: 9.5%).
Furthermore, the following sensitivity analyses  
(stress testing) are performed over the value in  
use calculation:
 · Commodities, including aluminium, alumina, caustic, 
coal, oil and gas price fluctuations (plus or minus 
10%). AWAC’s future cash flows are most sensitive  
to alumina price fluctuations.
 · Currency rate fluctuation (plus or minus 10%).
 · Increased WACC.
As a final check, the carrying value of the investment  
in associates is compared to Alumina Limited’s market 
capitalisation and to major analysts’ valuations.
An impairment loss is recognised for the amount  
by which the asset’s carrying amount exceeds its 
recoverable amount. The recoverable amount is the 
higher of an asset’s fair value less costs to sell and 
value in use. 
Alumina LimitedAnnual Report 202375
In the year ended 31 December 2023, a potential impairment trigger was identified and, accordingly, 
management estimated the recoverable value for the Group’s investment in AWAC. 
The recoverable amount of the investment in AWAC exceeds its carrying value and, therefore, no impairment  
loss was recognised in the year ended 31 December 2023 (2022: nil).

d) Commitments and contingent  
liabilities for AWAC
Contingent liabilities – claims
There are potential obligations due to the various 
lawsuits and claims and proceedings which have been, 
or may be, instituted or asserted against entities within 
AWAC, including those pertaining to environmental, 
safety and health and tax matters. While the amounts 
claimed may be substantial, the ultimate liability cannot 
now be determined because of the considerable 
uncertainties that existed at balance date. Therefore,  
it is possible that the results of operations or liquidity  
in a particular period could be materially affected by 
certain contingencies.
Pursuant to the terms of the AWAC Formation 
Agreement, Arconic Inc, Alcoa Corporation and 
Alumina Limited have agreed to remain liable for 
Extraordinary Liabilities (as defined in the agreement) 
as well as for certain other pre-formation liabilities, 
such as environmental conditions, to the extent of  
their pre-formation ownership of the AWAC entity  
or asset with which the liability is associated.
As previously reported, the Australian Taxation Office 
(ATO) has undertaken a transfer pricing examination  
in respect of certain historical third-party alumina  
sales made by Alcoa of Australia Limited (AoA) over  
a 20-year period. As a result of that examination,  
the ATO had issued a statement of audit position 
(SOAP) to AoA. The SOAP was the subject of an 
internal review process within the ATO. 
The ATO completed that process, and on 7 July 2020 
issued AoA with Notices of Assessment (the Notices)  
in respect of this matter. The Notices assert claims  
for additional income tax payable by AoA of 
approximately A$214 million. The Notices also include 
claims for compounded interest on the primary tax 
amount totalling approximately A$707 million. 
In accordance with the ATO’s dispute resolution 
practices, on 30 July 2020, AoA paid 50% of the 
assessed primary income tax amount (exclusive of 
interest and any penalties), being approximately 
A$107 million, out of cash flows. In exchange, the  
ATO will not seek further payment prior to final 
resolution of the matter. 
On 17 September 2020, the ATO issued a position 
paper with its preliminary view on the imposition of 
administrative penalties related to the tax assessment 
issued to AoA. This paper proposed penalties of 
approximately A$128 million.
Alumina LimitedAnnual Report 202377
AoA disagreed with the Notices and with the ATO’s 
proposed position on penalties. In September 2020, 
AoA lodged formal objections to the Notices. In the 
fourth quarter of 2020, AoA provided a submission on 
the ATO’s imposition of interest, and also submitted a 
response to the ATO’s position paper on penalties. AoA 
submissions propose that the interest amount should  
be remitted (i.e. should not be fully payable) and no 
penalties should be payable. After the ATO completes 
its review of AoA’s response to the penalties position 
paper, the ATO could issue a penalty assessment. 
On 1 February 2022, AoA submitted statutory notices 
to the ATO requiring the ATO to make decisions on 
AoA’s objections within a 60-day period. On 1 April 
2022, the ATO issued its decision disallowing the 
Company’s objections related to the income tax 
assessment, while the position on penalties and 
interest remains outstanding. 
On 29 April 2022, AoA filed proceedings in the 
Australian Administrative Appeals Tribunal (AAT) 
against the ATO to contest the Notices, a process 
which could last several years. The AAT held the first 
directions hearing on 25 July 2022 ordering AoA to  
file its evidence and related materials by 4 November 
2022, ATO to file its materials by 14 April 2023 and 
AoA to file reply materials by 26 May 2023. AoA filed 
its evidence and related materials on 4 November 
2022. The ATO filed its evidence on 13 November 
2023, after seeking and being granted a series  
of extensions. AoA filed reply evidence on  
15 March 2024. The matter is listed for hearing  
before the AAT on 3 to 28 June 2024.
AoA’s obligation to make any further payment of  
the primary tax amount, or payment of any penalty  
or interest amount, will be determined through the 
objection and court processes available to AoA.  
If AoA is ultimately fully successful, the 50%-part 
payment to the ATO would be refunded. Further 
interest on the unpaid amounts will continue to  
accrue during the dispute. 
The Company understands that AoA will defend  
its position in respect of the ATO’s Notices and  
any penalties imposed.
St. Croix Proceedings – Abednego  
and Abraham cases.
In January 2010, Alcoa Corporation was served with  
a multi-plaintiff action complaint involving several 
thousand individual persons claiming to be residents 
of St. Croix alleging personal injury or property 
damage from Hurricane Georges or winds blowing 
material from the St. Croix Alumina, L.L.C. (SCA)  
facility on the island of St. Croix (U.S. Virgin Islands). 
This complaint, Abednego, et al. v. Alcoa, et al.,  
which added the then current owners of the facility  
to a February 1999 action, was filed in the Superior  
Court of the Virgin Islands, St. Croix Division.
In 2012, Alcoa was served with a separate multi-plaintiff 
action alleging claims essentially identical to those  
set forth in the Abednego v. Alcoa complaint. In 2015, 
the Superior Court dismissed all plaintiffs’ complaints 
without prejudice, permitting the plaintiffs to re-file  
the complaints individually. In 2017, the court issued  
an order that consolidated all timely complaints into  
the Red Dust Claims docket (Master Case No.: SX-15-
CV-620). Following this order, a total of approximately 
430 complaints were filed and accepted by the court, 
which included claims of approximately 1,360 
individuals. In November 2018, the Red Dust Claims 
docket was transferred to the Complex Litigation 
Division within the Superior Court of the Virgin Islands. 
At such time, the Alcoa was unable to reasonably 
predict an outcome or to estimate a range of reasonably 
possible loss, and thereafter the Red Dust Claims docket 
became inactive for several years. The Court issued an 
amended case management order dividing the 
complaints filed in the Red Dust docket into groups  
of 50 complaints, designated Groups A though I in 
March 2022. The parties selected 10 complaints from 
Group A to proceed to trial as the Group A lead cases.  
In November 2023, the Court issued an amended case 
management order with regard to the Group A lead 
cases scheduling trials to begin in July 2024. Trials with 
regard to the Group A lead cases will continue through 
March 2025. Concurrently, the Court is considering 
discovery issues with respect to other group cases. 
Alcoa remains unable to reasonably predict an outcome 
or to estimate the range of reasonably possible loss  
in the Red Dust Claims docket cases.
Commitments
AWAC has outstanding bank guarantees and letters  
of credit primarily related to environmental and  
leasing obligations, legal matters, and customs  
duties, among others. The total amount committed 
under these instruments, which automatically renew  
or expire at various dates, between 2024 and 2025, 
was $128.0 million at 31 December 2023.
AWAC has outstanding surety bonds primarily  
related to customs duties. The total amount committed 
under these bonds, which automatically renew or 
expire at various dates, between 2026 and 2028,  
was $22.7 million at 31 December 2023.

The Group’s exposure to various risks associated with the financial instruments is disclosed in Note 5.  
The maximum exposure to credit risk at the end of the reporting period is the carrying amount of each class  
of financial assets mentioned above. The carrying amounts of financial assets and liabilities approximate their  
fair values.
a) Cash and cash equivalents 
Cash and cash equivalents comprise cash on hand, deposits held at call with financial institutions, other short- 
term highly liquid investments with original maturities of three months or less that are readily convertible to  
known amounts of cash and which are subject to an insignificant risk of changes in value, and bank overdrafts.

4. FINANCIAL ASSETS AND LIABILITIES (continued)
b) Borrowings 
Borrowings are initially recognised at fair value, net of transaction costs incurred. Borrowings are subsequently 
measured at amortised cost. Any difference between the proceeds (net of transaction costs) and the redemption 
amount is recognised in profit or loss over the period of the borrowings using the effective interest method.
Fees paid on establishment of loan facilities are recognised as transaction costs to the extent that it is probable 
that some or all of a facility will be drawn down. In this case, the fee is deferred until the draw down occurs. To the 
extent there is no evidence that it is probable that some or all of a facility will be drawn down, the fee is capitalised 
as a prepayment for the liquidity services and amortised over the period of the facility to which it relates.
Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement  
of the liability for at least 12 months after the balance sheet date. Refer to note 5(c).

Financial risk management is carried out by the Treasury Committee which is responsible for developing and 
monitoring risk management policies. Risk management policies are established to identify and analyse the  
risks faced by the Group, to set appropriate risk limits and controls, and to monitor risks and adherence to limits.  
Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the 
Group’s activities.

a) Market risk
Foreign exchange risk 
Foreign exchange risk for the Group arises when future commercial transactions and recognised assets  
and liabilities are denominated in a currency that is not the Group’s functional currency.
Except as described above, the Group generally does not hedge its foreign currency exposures except  
through the near-term purchase of currency to meet operating requirements.

Borrowings by the Group at variable rates expose it to cash flow interest rate risk. Borrowings at fixed rates would 
expose the Group to fair value interest rate risk. When managing interest rate risk the Group seeks to reduce the 
overall cost of funds. Group policy is to generally borrow at floating rates subject to availability of attractive fixed 
rate deals.

Had interest rates on floating rate debt during 2023 been one percentage point higher/lower than the average, 
with all other variables held constant, pre-tax profit for the year would have been US$2.3 million lower/higher 
(2022: US$0.5 million lower/higher). 
b) Credit risk 
Credit risk arises from cash and cash equivalents, derivative financial instruments and deposits with banks and 
financial institutions, as well as credit exposures to customers, including outstanding receivables and committed 
transactions. For banks and financial institutions, only independently rated parties with a minimum rating of ‘A-‘are 
accepted, and exposure limits are assigned based on actual independent rating under Board approved guidelines.
Credit risk further arises in relation to cross guarantees given to wholly owned subsidiaries (see Note 17 for 
details). Such guarantees are only provided in exceptional circumstances and are subject to Board approval.  
The carrying amount of financial assets recorded in the financial statements, net of any allowances for losses, 
represent the Group’s maximum exposure to credit risk. 
Alumina LimitedAnnual Report 202383
c) Liquidity risk 
Prudent liquidity risk management requires maintaining sufficient cash and credit facilities to ensure the Group’s 
commitments and plans can be met. This is managed by maintaining committed undrawn credit facilities to cover 
reasonably expected forward cash requirements. Management monitors rolling forecasts of the Group’s liquidity, 
including undrawn borrowing facilities and cash and cash equivalents on the basis of expected cash flows.
The Group had the following undrawn borrowing facilities at the end of the reporting period:

The Group’s objective when managing capital is to safeguard the ability to continue as a going concern, so  
that it can continue to provide returns for shareholders and to maintain an optimal capital structure to reduce  
the cost of capital.
The Board’s policy is to maintain a strong capital base so as to maintain investor, creditor and market confidence 
and to sustain future development of the business. In order to maintain or adjust the capital structure, the 
Company may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue  
new shares or sell assets to reduce debt.
The Group calculates the gearing ratio as net debt divided by total capital. Net debt is calculated as total 
borrowings less cash and cash equivalents. Total capital is calculated as ‘equity’ as shown in the balance  
sheet plus debt.

7. EXPENSES 
a) Employee benefits expense
Liabilities for salaries and annual leave are recognised 
in current provisions (i.e. short-term employee 
benefits), and are measured as the amount unpaid at 
the reporting date at expected pay rates in respect of 
employees’ services up to that date, including related 
on-costs. 
The liability for long service leave is recognised in the 
provision for employee benefits and measured as the 
present value of expected future payments to be made 
in respect of services provided by employees up to the 
reporting date. Consideration is given to expected 
future wage and salary levels, experience of employee 
departures and periods of service. Expected future 
payments are discounted using market yields at the 
end of the reporting period of high-quality corporate 
bonds with terms to maturity and currency that match, 
as closely as possible, the estimated future cash flows.
All employees of Alumina Limited are entitled to 
benefits upon retirement, disability or death from  
the Group’s superannuation plan. Alumina Limited’s 
employees are members of the Alumina Limited Super 
Plan managed by MLC MasterKey Super, except for 
employees who elected to contribute to an alternate 
fund. The plan is an accumulation category plan which 
offers a minimum Company contribution of 11 percent 
(10.5 percent prior 1 July 2023) of basic salary to each 
member’s account. Members also have the option  
to make voluntary contributions to their account. 
Employer contributions to these funds are recognised 
as an expense.

The income tax expense/benefit for the period is the tax payable/receivable on the current period’s taxable 
income based on the applicable income tax rate for each jurisdiction adjusted by changes in deferred tax assets 
and liabilities attributable to temporary differences and unused tax losses.
The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at  
the reporting period in the countries where the Company’s subsidiaries and associates operate and generate 
taxable income.

Deferred income tax is provided in full, using the liability 
method, on temporary differences arising between the 
tax bases of assets and liabilities and their carrying 
amounts in the consolidated financial statements. 
Deferred income tax is determined using tax rates (and 
laws) that have been enacted or substantially enacted 
by the reporting date and are expected to apply when 
the related deferred income tax asset is realised or the 
deferred income tax liability is settled.
Deferred tax assets are recognised for deductible 
temporary differences and unused tax losses only if it is 
probable that future taxable amounts will be available 
to utilise those temporary differences and losses.
Deferred tax liabilities and assets are not recognised 
for temporary differences between the carrying 
amount and tax bases of investments in controlled 
entities where the parent entity is able to control 
the timing of the reversal of the temporary differences  
and it is probable that the differences will not reverse 
in the foreseeable future.
Deferred tax assets and liabilities are offset when there 
is a legally enforceable right to offset current tax assets 
and liabilities and when the deferred tax balances 
relate to the same taxation authority. Current tax assets 
and liabilities are offset where the entity has a legally 
enforceable right to offset and intends either to settle 
on a net basis, or to realise the asset and settle the 
liability simultaneously.
Alumina Limited and its wholly-owned Australian 
controlled entities have implemented the tax 
consolidation legislation. As a consequence, these 
entities are taxed as a single entity and the deferred 
tax assets and liabilities of these entities are set off  
in the consolidated financial statements.
The Group’s deferred tax assets and liabilities are attributable to the following:
Deferred tax liabilities
Right of use asset
Total deferred tax liabilities

Employee benefits
Lease liability

15. EVENTS OCCURRING AFTER THE  
REPORTING PERIOD
Curtailment of Kwinana Alumina Refinery 
On 8 January 2024, Alcoa Corporation announced 
plans to fully curtail the Kwinana refinery in Western 
Australia (“WA”), beginning in the second quarter  
of 2024. The decision to curtail the refinery came in 
response to losses incurred at the refinery together 
with its age, scale, high costs of operation and current 
bauxite grades. Since the start of 2023, the refinery  
had been operating at approximately 80 per cent  
of its annual capacity. 
The Kwinana refinery and associated residue storage 
areas will continue to be actively managed by Alcoa. 
Alcoa’s facilities in the Port of Kwinana will also 
continue to operate to import raw materials and export 
alumina produced at the Pinjarra refinery. Production  
at the Pinjarra and Wagerup refineries is not expected 
to be impacted by the curtailment at Kwinana.
A Scheme Implementation Deed with Alcoa 
Corporation
Alumina Limited (“Alumina”) announced on  
12 March 2024 that it has entered into a Scheme 
Implementation Deed (“SID”) with Alcoa Corporation 
(“Alcoa”) in relation to a proposal for Alcoa to acquire 
100% of the fully paid ordinary shares in Alumina by 
way of a scheme of arrangement (“the Transaction”). 
Under the terms of the SID, eligible Alumina 
shareholders will be entitled to receive 0.02854  
shares of Alcoa common stock (in the form of ASX-
listed Alcoa CHESS Depositary Interests (CDIs)) for 
each Alumina share held.
The Independent Non-executive Directors and 
Managing Director and CEO of Alumina recommend 
that Alumina shareholders vote in favour of the 
Transaction, in the absence of a superior proposal  
for Alumina and subject to the independent  
expert concluding (and continuing to conclude)  
that the Transaction is in the best interests of Alumina 
shareholders. The Non-Independent Non-executive 
Director of Alumina abstained from making a 
recommendation. 
The SID is subject to customary deal protections for 
both Alcoa and Alumina, including no shop, no talk,  
no due diligence and notification obligations. Alumina 
is also bound by other customary provisions, including 
a matching right for Alcoa in the event of a competing 
proposal for Alumina. The Transaction is subject to a 
number of conditions, including approval of Alumina 
shareholders at a scheme meeting.
16. PARENT ENTITY FINANCIAL 
INFORMATION
The financial information for the parent entity has  
been prepared on the same basis as the consolidated 
financial statements, except as set out below.
Investments in subsidiaries, associates and 
joint venture entities
Investments in subsidiaries, associates and joint 
venture entities are accounted for at cost in the 
financial statements of Alumina Limited. Dividends 
received from associates are recognised in the parent 
entity’s profit or loss, rather than being deducted  
from the carrying amount of these investments.
Where the parent entity has provided financial 
guarantees in relation to loans and payables of 
subsidiaries for no compensation, the fair values of 
these guarantees are accounted for as contributions 
and recognised as part of the cost of the investment.
Intercompany loans
Loans granted by the parent entity to its subsidiaries 
are classified as non-current assets. 
Tax consolidation legislation
Alumina Limited and its wholly-owned Australian 
controlled entities have implemented tax consolidation 
legislation. The head entity, Alumina Limited, and the 
controlled entities in the tax consolidated Group 
account for their own current and deferred tax 
amounts. These tax amounts are measured as if each 
entity in the tax consolidated Group continues to be  
a standalone taxpayer in its own right. In addition to  
its own current and deferred tax amounts, Alumina 
Limited also recognises the current tax liabilities  
(or assets) and the deferred tax assets arising from 
unused tax losses and unused tax credits assumed 
from controlled entities in the tax consolidated Group.

AWAC companies. 
Guarantees relating to Alumina Espanola SA 
(‘Espanola’)
Alumina Limited has proportionally (40%) guaranteed 
the payment of the obligations of Espanola in relation 
to certain financial services provided by a bank. The 
maximum amount payable under the guarantee is 
EUR10.0 million and the guarantee expires on 15th 
October 2024.
Alumina Limited has agreed to guarantee the 
proportional share of Espanola's obligations (40%)  
for the purchase of natural gas for alumina refining 
operations at the San Ciprian refinery. The maximum 
amount guaranteed by Alumina Limited shall not 
exceed EUR8.0 million. The guarantee by Alumina 
Limited has expired on 29 February 2024. However, 
Alumina Espanola’s gas contract is renewed as a 
periodic agreement and, accordingly, the proportional 
guarantee issued by Alumina Limited is expected to  
be extended.

of Espanola through an intercompany short-term  
loan agreement if required. This will expire on the  
27th September 2025.
In addition, the parent entity has entered into a Deed 
of Cross Guarantee with the effect that it guarantees 
the debts of its wholly-owned subsidiaries. Further 
details of the Deed of Cross Guarantee are disclosed 
in Note 17. 
No liability was recognised by the parent entity of the 
group in relation to the above mentioned guarantees, 
as the fair values of the guarantees are immaterial.
c) Contingent liabilities of the parent entity

Alumina LimitedAnnual Report 202399
Material uncertainty related to going concern
We draw attention to the section “Basis of preparation 
– going concern” in the Notes to the consolidated 
financial statements which describes that Alumina 
Limited has entered into a Scheme Implementation 
Deed with Alcoa Corporation and completion of the 
transaction will give rise to a Review Event under 
Alumina’s syndicated revolving cash advance facility 
agreement. These conditions, along with other matters 
set forth in the section “Basis of preparation – going 
concern”, indicate that a material uncertainty exists that 
may cast significant doubt on the Group's ability to 
continue as a going concern. Our opinion is not 
modified in respect of this matter.
Our audit approach
An audit is designed to provide reasonable assurance 
about whether the financial report is free from material 
misstatement. Misstatements may arise due to fraud  
or error. They are considered material if individually  
or in aggregate, they could reasonably be expected 
to influence the economic decisions of users taken  
on the basis of the financial report.
We tailored the scope of our audit to ensure that we 
performed enough work to be able to give an opinion 
on the financial report as a whole, taking into account 
the geographic and management structure of the 
Group, its accounting processes and controls and  
the industry in which it operates.
The Group’s sole business undertaking is investing 
globally in bauxite mining and alumina refining with 
some minor alumina-based chemical businesses and 
aluminium smelting operations. All of these business 
activities are conducted through the Group’s 40% 
investment in several entities (including Alcoa of 
Australia Limited) which collectively form Alcoa World 
Alumina and Chemicals (AWAC). Alcoa Corporation 
owns the remaining 60% of AWAC and is the manager 
of these business activities. The Group’s equity interest 
in AWAC forms one reportable segment. The Group 
participates in AWAC through the Strategic Council, 
which consists of three members appointed by  
Alcoa Corporation and two members appointed by  
the Group. As the Group does not control or operate 
the AWAC assets, its role involves strategic investment 
management on behalf of its shareholders. 
Accordingly, this investment has been determined  
to be in an associate and is accounted for under the 
equity method.
Audit Scope
 · Our audit focused on where the Group made 
subjective judgements; for example, significant 
accounting estimates involving assumptions and 
inherently uncertain future events.
 · The Group engagement team directed the 
involvement of the component audit teams,  
which performed an audit of the financial  
information of Alcoa of Australia and AWAC.
 · The Group engagement team determined and 
undertook an appropriate level of involvement in  
the work performed by the component audit teams, 
in order for us to be satisfied that sufficient audit 
evidence had been obtained to support our opinion 
on the Group financial report as a whole. We had 
regular communication with the component audit 
teams throughout the year and performed a review 
of their audit working papers.
 · We audited the equity accounting for Alumina’s  
40% investment in AWAC. This process included 
auditing certain adjustments made by Alumina to 
convert the AWAC results (which are prepared under 
US GAAP), to comply with Australian Accounting 
Standards (AAS).
Key audit matters
Key audit matters are those matters that, in our 
professional judgement, were of most significance in 
our audit of the financial report for the current period. 
The key audit matters were addressed in the context  
of our audit of the financial report as a whole, and in 
forming our opinion thereon, and we do not provide  
a separate opinion on these matters. Further, any  
commentary on the outcomes of a particular audit 
procedure is made in that context. We communicated 
the key audit matters to the Audit and Risk Committee.
In addition to the matter described in the Material 
uncertainty related to going concern section, we have 
determined the matters described below to be the key 
audit matters to be communicated in our report.
100  
Key audit matter
How our audit addressed the key audit matter
Equity accounting for Alumina Limited’s  
investment in AWAC
(Refer to note 2)
Alumina Limited’s equity accounted investment in AWAC  
is carried at US$1,729.5 million and its current year share  
of the net loss of AWAC, accounted for using the equity 
accounting method, is US$119.4 million. 
The equity accounting method requires consistent 
accounting standards to be applied by the investing 
company and its associates. Alcoa of Australia Limited, a 
component of AWAC, already prepares financial information 
under Australian Accounting Standards (AAS), therefore no 
conversion is required.
The financial information of AWAC entities other  
than Alcoa of Australia Limited is prepared under US 
Generally Accepted Accounting Principles (US GAAP), 
therefore adjustments are required to convert certain 
amounts to comply with AAS.
We determined equity accounting for Alumina Limited's 
investment in AWAC to be a key audit matter because of the 
magnitude of the investment in associates balance and the 
complexity and significance of, and judgement involved, in 
preparing the adjustments required by the Group to convert 
amounts accounted for under US GAAP to AAS.
Judgement is involved in determining the differences  
in the accounting for areas such as the asset retirement 
obligation provisions, removal and restoration of certain 
refineries, defined pension plans, and the reversal of fixed 
asset uplifts included in Alcoa World Alumina Brasil Ltda.
To assess the equity accounting for the Group’s  
40% investment in AWAC, we performed a number  
of procedures, including the following:
 · Assessed the appropriateness of the Group’s equity 
accounting method in accordance with AASB 128 
Investments in Associates and Joint Ventures;
 · Agreed the financial information of Alcoa of Australia 
Limited accounted for under AAS to the equity accounting 
schedule prepared by the Group;
 · Agreed the financial information of AWAC accounted  
for under US GAAP to the equity accounting schedule 
prepared by the Group;
 · Considered adjustments required to convert amounts 
accounted for under US GAAP to comply with AAS.  
To do this we:
 — Tested on a sample basis US GAAP to AAS adjustments 
by agreeing the adjustments to supporting schedules 
and documentation, considering the appropriateness  
of any judgements made; and
 — Considered the completeness of the US GAAP  
to AAS adjustments
 · Reconciled the opening equity accounted investment 
balance to the final balance reflected in the financial 
report. To do this we:
 — Recalculated the share of net loss and other 
comprehensive income of AWAC by examining the 
schedule prepared by the Group and recalculating 
Alumina’s 40% share; and,
 — On a sample basis, tested dividends received and 
additional investments made through cash calls to the 
relevant declaration documents and bank statements.
 · We assessed the reasonableness of the disclosures  
made in the financial report in accordance with the 
requirements of Australian Accounting Standards.
Impairment testing of Alumina Limited’s equity
accounted investment in AWAC
(Refer to note 2) 
The carrying value of Alumina’s equity accounted 
investment in AWAC is US$1,729.5 million. In accordance 
with Australian Accounting Standards, the Group concluded 
that indicators of impairment exist as at 31 December 2023 
and prepared a calculation to estimate the recoverable 
amount of the investment. 
To evaluate the Group’s assessment of the recoverable 
amount of the AWAC investment we performed  
a number of procedures, including the following:
 · Evaluated the methodology adopted in the  
Group’s discounted cash flow model;
 · Assessed the mathematical accuracy of the  
discounted cash flow model;
 · Assessed the reasonableness of certain historical 
assumptions to actual results;
The Group concluded that the recoverable amount of the 
investment exceeded the carrying value, and therefore no 
impairment charge has been recorded. 
 · Assessed the appropriateness of certain assumptions  
in the model, including consideration of available 
external evidence; 
The recoverable amount was estimated using the Value in 
Use (“VIU”) methodology, which requires the estimation of 
future cash flows to prepare a discounted cash flow model. 
 · With the support of our valuation experts, we assessed 
the VIU model and discount rates, amongst other 
assumptions; and
The model prepared by the Group contains a number  
of significant assumptions including future alumina and 
aluminium prices, exchange rates, energy prices, other input 
prices and discount rate. Changes in these assumptions  
can have a significant impact on the headroom available  
in the impairment assessment. 
The assessment was considered to be a key audit matter 
because of the level of judgement applied by the Group  
in the estimating the recoverable amount of the investment.
 · Evaluated the reasonableness of the disclosures  
made in Note 2 (b) of the financial report, including 
those regarding methodology and key assumptions  
in light of the requirements of the Australian  
Accounting Standards.

Other information
The directors are responsible for the other information. 
The other information comprises the information 
included in the annual report for the year ended  
31 December 2023, but does not include the financial 
report and our auditor’s report thereon.
Our opinion on the financial report does not cover  
the other information and accordingly we do not 
express any form of assurance conclusion thereon 
through our opinion on the financial report. We have 
issued a separate opinion on the remuneration report.
In connection with our audit of the financial report,  
our responsibility is to read the other information and, 
in doing so, consider whether the other information is 
materially inconsistent with the financial report or our 
knowledge obtained in the audit, or otherwise appears 
to be materially misstated.
If, based on the work we have performed on the  
other information that we obtained prior to the date  
of this auditor’s report, we conclude that there is a 
material misstatement of this other information, we  
are required to report that fact. We have nothing to 
report in this regard. 
Responsibilities of the Directors for  
the Financial Report
The directors of the Company are responsible for the 
preparation of the financial report that gives a true and 
fair view in accordance with Australian Accounting 
Standards and the Corporations Act 2001 and for such 
internal control as the directors determine is necessary 
to enable the preparation of the financial report that 
gives a true and fair view and is free from material 
misstatement, whether due to fraud or error.
In preparing the financial report, the directors are 
responsible for assessing the ability of the Group to 
continue as a going concern, disclosing, as applicable, 
matters related to going concern and using the going 
concern basis of accounting unless the directors either 
intend to liquidate the Group or to cease operations, 
or have no realistic alternative but to do so.
Auditor’s responsibilities for the  
Audit of the Financial Report
Our objectives are to obtain reasonable assurance 
about whether the financial report as a whole is free 
from material misstatement, whether due to fraud or 
error, and to issue an auditor’s report that includes  
our opinion. Reasonable assurance is a high level  
of assurance, but is not a guarantee that an audit 
conducted in accordance with the Australian Auditing 
Standards will always detect a material misstatement 
when it exists. Misstatements can arise from fraud or 
error and are considered material if, individually or in 
the aggregate, they could reasonably be expected to 
influence the economic decisions of users taken on  
the basis of the financial report.
A further description of our responsibilities for 
the audit of the financial report is located at the 
Auditing and Assurance Standards Board website at:
