Article 5: Division of Revenues from the Unit Area

1. The Parties shall share equally revenue derived directly from the production of that petroleum lying within the Unit Area in so far as the revenue relates to the upstream exploitation of that petroleum.

2. The value of petroleum upstream shall be determined on the basis of arm’s length principles.

3. The Australian revenue component means taxation revenue collected from:

(a) the petroleum resource rent tax;

(b) company tax (including capital gains tax); and

(c) first tranche petroleum and profit petroleum pursuant to the Timor Sea Treaty;

 or subsequent taxes of a similar nature.

4. The Australian revenue component shall be determined as follows:

(a) Revenue relating to the petroleum resource rent tax is the actual revenue collected each quarter adjusted:

(i) to include expenditures related to the petroleum activities undertaken within the Unit Area transferred out of this project and to exclude expenditures not related to the petroleum activities undertaken within the Unit Area transferred into this project; and

(ii) in the anticipated last 5 years of the project’s life, to include estimated closing down costs (subject to reconciliation against actual closing down costs once the project has closed down).

b) Revenue relating to company tax is the actual revenue collected each quarter adjusted to determine the company tax position of the entity’s upstream operations relating to the petroleum activities undertaken within the Unit Area.

(c) The adjustment referred to in sub-paragraph (b) of this paragraph is based on:

(i) allocating direct revenues and direct deductible non-interest expenses between the upstream operations in the Unit Area and other operations of the entity;

(ii) allocating indirect revenues and indirect deductible non-interest expenses between the upstream operations in the Unit Area and the other operations of the entity in the same proportions as direct revenues and direct deductible expenses respectively; and

(iii) allocating deductible interest expenses between the upstream operations in the Unit Area and the other operations of the entity in the same proportion as the final allocation of deductible non-interest expenses.

(d) Revenue relating to first tranche petroleum and profit petroleum is the actual revenue collected each quarter.

5. The Timor-Leste revenue component means taxation revenue collected from first tranche petroleum, profit petroleum and all profit-based income taxes calculated and levied by annual assessment pursuant to the Timor Sea Treaty, or subsequent taxes of a similar nature, but excludes Value Added Tax or income tax withheld monthly or similar taxes, or subsequent taxes of a similar nature.

6. The Timor-Leste revenue component shall be determined based on actual revenue collected each quarter.

7. Each Party shall notify the other Party of the revenue amount (in domestic currency terms) relating to the quarter on the first working day in both Australia and Timor-Leste on or after 90 days following the end of that quarter.

8. Australia’s revenue amount in USD terms shall be:

(a)    determined on the first business day in both Sydney and Dili on or after 20 days following the notification referred to in paragraph 7 of this Article; and

(b)    based on the simple average of the USD/AUD exchange rate published by the Reserve Bank of Australia at 4.00 pm (Australian Eastern Standard Time) on that day, the two preceding days, and the two subsequent days.

9. Australia shall make a payment in USD to Timor-Leste equivalent to half the aggregate of the Australian revenue component (in USD terms) and the Timor-Leste revenue component, less the Timor-Leste revenue component (in USD terms), on the first business day in both Sydney and Dili on or after 30 days following notification referred to in paragraph 7 of this Article.

10. In the event that Timor-Leste’s revenue component exceeds Australia’s revenue component in USD terms in a particular quarter, Timor-Leste shall not make a payment to Australia, and subsequent quarterly payments by Australia to Timor-Leste shall be adjusted to take account of the earlier payment not made by Timor-Leste.

11. Australia and Timor-Leste shall inform each other expeditiously of changes in their respective taxation policies and laws that may impact on the revenue derived directly from the production of petroleum in the Unit Area. Where one Party notifies the other that it considers that a change in the taxation laws of the other Party is likely to have a serious impact on the revenue to be received by the first Party:

(a)    the Parties shall, as a matter of urgency, consult with a view to resolving the matter; and

(b)   where the Parties are unable to resolve the matter pursuant to sub-paragraph (a) of this paragraph within a reasonable period, the matter shall be referred immediately to the Maritime Commission established in Article 9.

12. The Parties agree that during the period of this Treaty, the totality of financial payments from one Party to another concerning or relating to the exploration and exploitation of maritime areas between Australia and Timor-Leste are defined by the treaties and agreements referred to in paragraph 1 of Article 7 and such agreed associated documentation relating to those treaties and agreements that exists at the time of the entry into force of this Treaty, and neither Party shall seek additional payments.

13. The Parties shall establish procedures for the implementation of paragraphs 1 to 10 of this Article.

Article 6: Assessor

1. Either Party may request the appointment of an assessor to review adjustments used to calculate any one or more of the revenues referred to in paragraphs 3 and 5 of Article 5.

2. The Parties shall, within 30 days of a request being made to appoint an assessor, seek to reach agreement on the appointment of such an assessor. If, within this period, no agreement has been reached, the procedures for appointment specified in Annex I shall be followed.

3. The assessor shall act in accordance with the terms of Annex I.

4. The assessor’s conclusions shall be implemented by the Parties unless the Parties agree otherwise.

5. Where adjustments are made to previous payments as the result of a review by an assessor, interest will be added, calculated as follows:

D/360 x LIBOR x A

where:

A is the amount of the adjustment;

D is the difference in the number of days between the payment date referred to in paragraph 9 of Article 5 and the payment of A; and

LIBOR is determined on the payment date referred to in paragraph 9 of Article 5.

Timor-Leste and Australia shall make every effort to pursue cooperation in relation to highly migratory fish stocks, as defined in Annex 1 to the 1982 Convention, either directly or through appropriate subregional or regional fisheries management organisations, to ensure effective conservation and management of such stocks.

Dear Minister

I am writing to you concerning the application of paragraph 2 of Article 4 of the Treaty between the Government of Australia and the Government of the Democratic Republic of Timor-Leste on Certain Maritime Arrangements in the Timor Sea to the area of seabed outside the Joint Petroleum Development Area established under the Timor Sea Treaty and south of the line established by the Agreement between the Government of the Commonwealth of Australia and the Government of the Republic of Indonesia Establishing Certain Seabed Boundaries in the Area of the Timor and Arafura Seas. Supplementary to the Agreement of 18 May 1971.

As at 19 May 2002, Australian legislation applying to the area referred to in the preceding paragraph authorised the granting of permission for conducting activities in relation to petroleum or other resources of the seabed and subsoil. That legislation included the Petroleum (Submerged Lands) Act 1967 and. the Offshore Minerals Act 1994. Accordingly, Australia will continue activities (including the regulation and authorisation of existing and new activities) in that area.

I seek your confirmation that, as at 19 May 2002, Timor-Leste had no legislation applying to that area giving rise to the application of paragraph 2 of Article 4.

Yours sincerely

Alexander Downer
