(a) a participating person for an eligible revenue period has the same ultimate Australian parent entity as one or more other participating persons for the period; and

(3) As an alternative to subsection (2), 2 or more participating persons with the same ultimate Australian parent entity may make all of the calculations required by Parts 3 and 4 on a group basis, identifying and accounting for revenue and deductions as a whole.

Note: See section 38 for the calculation of net telecommunications sales revenue for participating persons within a group.

(4) In this determination, the use of the accounting arrangements in subsection (3) is accounting on a group basis.

14 Sales revenue

(1) In this determination, the sales revenue of a participating person, or of a consolidated related party or declared related party of a participating person, for an eligible revenue period (the eligible revenue period) is to be worked out using the sources mentioned in subsections (2) and (4) to identify the amount of revenue for the period (the relevant period) occurring during the eligible revenue period, in which the participating person:

(a) is a carrier; or

(b) is a participating carriage service provider; or

(2) For subsection (1), the sources are:

(a) for an entity (other than a declared related party), if the entity’s sales revenue is included in the annual consolidated financial statements of an ultimate Australian parent entity:

(i) if the most recent financial statements of the ultimate Australian parent entity for a period ending no later than the end of the eligible revenue period are required to be audited under the Corporations Act 2001 or any other law of the Commonwealth, a State or a Territory—those audited financial statements; and

(ii) in any other case—the most recent financial statements of the ultimate Australian parent entity for a period ending no later than the end of the eligible revenue period; or

(b) for an entity (other than a declared related party), if the entity’s sales revenue is not included in the annual consolidated financial statements of an ultimate Australian parent entity:

(i) if the most recent financial statements of the participating person that include the participating person’s sales revenue for a period ending no later than the end of the eligible revenue period are required to be audited under the Corporations Act 2001 or any other law of the Commonwealth, a State or a Territory—those audited financial statements; and

(ii) in any other case—the most recent financial statements of the participating person that include the participating person’s sales revenue for a period ending no later than the end of the eligible revenue period; or

(i) if the most recent financial statements of the declared related party that include the declared related party’s sales revenue for a period ending no later than the end of the eligible revenue period are required to be audited under the Corporations Act 2001 or any other law of the Commonwealth, a State or a Territory—those audited financial statements; and

(ii) in any other case—the most recent financial statements of the declared related party that include the declared related party’s sales revenue for a period ending no later than the end of the eligible revenue period.

(3) For subsection (1), revenue is revenue for the relevant period if the following conditions apply:

(a) the revenue is reported in:

(i) the last financial statements for a period ending no later than the end of the eligible revenue period; or

(ii) if the financial statements mentioned in subparagraph (i) cover a period that is shorter than the relevant period—those financial statements and the financial statements for as many other previous periods that, when added together, total a period that is at least the same length as the relevant period;

(b) if the financial statements mentioned in subparagraph (a)(i) or (ii) cover a period that is longer than the relevant period or does not include the whole or part of the relevant period—the revenue was earned in a particular period that:

(i) is the same length as the relevant period; and

(ii) the ACMA decides is the most appropriate period, included in the period covered by the financial statements, for matching with the relevant period.

Note: For example, an entity’s financial statements cover the period from 1 April in a year to 31 March in the following year. The relevant period runs from 1 July in the first-mentioned year to 30 June in the following year. Although the first 3 months of the period covered by the financial statements are outside the relevant period, the revenue earned in those months may be treated as part of the entity’s revenue for the relevant period, if the ACMA decides that those months form part of the most appropriate period for matching with the relevant period (since the financial statements for the subsequent period which covers the corresponding months, cannot be considered because of subparagraph 14(3)(a)(i)).

(4) If none of the sources mentioned in subsection (2) identifies the amount of an entity’s sales revenue for a relevant period, the sales revenue for that period is to be worked out using as many sources as are necessary to identify the entity’s sales revenue for the period.

Note: See section 17 for how to work out initial sales revenue based on sources identified in this section.

(5) If the ACMA makes a decision under subparagraph (3)(b)(ii), the ACMA must give to the participating person mentioned in subsection (1) a written notice of the decision, which includes a statement to the effect that if the person is adversely affected by the decision, the person may, subject to the Administrative Review Tribunal Act 2024:

(a) make an application to the Administrative Review Tribunal for review of the decision; and

(b) request a statement of reasons for the decision under that Act.

Note: See section 41 in relation to review of decisions.

15 Bundled revenue

(1) To work out an amount of revenue to be deducted under Part 3 or 4 (deductible revenue), a participating person for an eligible revenue period must:

(a) separate the deductible revenue, or a kind of deductible revenue, from other amounts with which the deductible revenue is bundled; and

(b) deal only with the deductible revenue.

(2) An amount of revenue is bundled revenue if the revenue:

(a) comes from different sources or acts; and

(b) is received in a way that does not show how much of the amount came from the individual sources or acts.

(3) Bundled revenue may also include the value of a benefit or service.

(4) The ACMA may declare, in writing, that a specified amount of revenue of a specified participating person, or a specified consolidated related party or declared related party of a participating person, is bundled revenue.

(5) The declaration may apply to more than one participating person, consolidated related party or declared related party (but not to all participating persons or parties).

(6) The declaration must also:

(a) specify the amount of bundled revenue; and

Part 3 — Gross telecommunications sales revenue

16 Purpose of Part

(b) multiply that amount by the declared related party factor for that party.

(3) Add the amounts worked out under subsection (2) (if any) to the amounts worked out under subsection (1).

(4) Subject to subsection (5), the result is the participating person’s initial sales revenue for the eligible revenue period.

(a) is non‑telecommunications sales revenue of a declared related party of the participating person; and

(b) is equal to the result of multiplying the whole amount of that revenue by the declared related party factor for that party; and

(3) If the participating person wants to deduct an amount (a deductible amount) from the participating person’s initial sales revenue under this section, the deductible amount must not be more than the total amount (if any) received by the participating person, or a consolidated related party or declared related party of the participating person, in connection with the activity that created the deductible amount.

Note: For example, if the participating person supplies gas services at a price that includes a subsidy provided by the participating person, the net amount received by the participating person for the supply can be a deductible amount.
