What 'Control' Really Means Under AASB 10: The Test Behind Every Group Consolidation

This article assumes a group of Australian-domiciled entities reporting in AUD, with wholly owned subsidiaries, all on Xero. Foreign subsidiaries add AASB 121 foreign currency translation, and partly owned subsidiaries add non-controlling interests. Both are outside the scope of this article.

Why the control question comes first

An ASX or NSX junior explorer running more than one entity in the group, for example a listed head company plus one wholly owned subsidiary that holds the exploration tenements, can end up treating group consolidation as a mechanical exercise: add the two trial balances together, eliminate the intercompany balances, done. That mechanical work is real, but it rests on a prior question that AASB 10 Consolidated Financial Statements answers first: does the parent actually control the subsidiary? For a wholly owned subsidiary with no joint venture partner and no external operator, the answer is usually straightforward. It stops being straightforward the moment an arrangement gives an outside party rights over the subsidiary's own decisions, for example a joint venture partner or operator with a say in the subsidiary's exploration program, or where voting rights do not map neatly to ownership percentage.

What AASB 10 actually tests

AASB 10 is the accounting standard that determines when one entity must consolidate another into a single set of financial statements. Paragraph 7 of the standard sets out three elements, and all three have to be present together before control exists: power over the investee, exposure or rights to variable returns from the investee, and the ability to use that power to affect the amount of those returns. Miss any one of the three and, under the standard, there is no control, regardless of what the share register says.

Power is not the same as ownership

For a 100% owned exploration subsidiary, power and ownership usually point the same way, but they are not the same test. AASB 10 defines power as existing rights that give the current ability to direct the subsidiary's relevant activities, meaning the activities that significantly affect its returns. For a tenement-holding subsidiary, the relevant activities are the exploration decisions: where to drill, how much to spend, when to farm out or dispose of a tenement interest. A parent that holds all the voting shares and appoints the subsidiary's directors clearly has power over those decisions. A parent that holds the shares but has handed exploration decision-making to a joint venture partner or an external operator may not, no matter what the ownership percentage reads.

Variable returns, and the link that ties it together

The second element is easier to satisfy for a wholly owned subsidiary. Dividends, capital gains on disposal and any residual value on wind-up all count as variable returns, and a 100% owner is exposed to all of them by definition. Cost savings from combining operations can count too, where the parent captures a return other interest holders cannot access. The full three-element test is what separates a parent from, say, a secured lender. A lender holding a fixed and floating charge over the tenement is exposed to variable returns too, since a default changes what it recovers, but its rights are protective, not a current ability to direct the exploration program, so they do not amount to power under AASB 10. A parent with full ownership and board control has power over the exploration decisions, is exposed to the tenement's returns, and can use that power to affect them. That combination of all three elements, not the ownership percentage on its own, is what AASB 10 treats as control.

Why it is still worth running the test explicitly

For a wholly owned subsidiary with board-appointed directors and no external operator, the control test tends to resolve the same way each time: full ownership, full exposure to the tenement's outcome, and power that paragraph 11 treats as straightforward when it flows directly from voting rights. It is still worth documenting explicitly, for two reasons. If the group later restructures so that a joint venture partner gains rights to direct the subsidiary's own exploration decisions, rather than simply farming into one tenement asset, the control question stops resolving itself automatically. And AASB 10 paragraph 8 requires the assessment to be reconsidered whenever facts and circumstances change one of the three elements, which means an arrangement signed mid-year can move a subsidiary in or out of the consolidated group part-way through a reporting period, not just at year end.

What control sets up

Once control is established, the mechanical work starts: aligning the chart of accounts across the two Xero organisations, eliminating the parent's investment against the subsidiary's equity, and reconciling the intercompany balances that build up between a head company raising capital and a subsidiary spending it in the field. We cover that structure itself, and where it breaks a single-entity checklist, in Two-Entity Xero Structures: How ASX Explorers Handle the Appendix 5B Across Head Company and Subsidiary.
