Aus57.1	In respect of jointly controlled operations and assets, the venturer shall disclose 
	the following information:
	(a)	the name and principal activities of each significant jointly controlled 
		operation or asset; 
	(b)	its percentage interest in the output of each significant jointly controlled 
		operation or asset during the annual reporting period; and
	(c)	for each category of assets, the aggregate amount employed in jointly 
		controlled operations or assets.

The "categories" referred to in paragraph Aus57.1(c) are the categories that the venturer has chosen to use to display its assets in its balance sheet or notes thereto.

For example, if BHP reported a line item for "mine transport equipment" in its balance sheet, if some of the equipment relates to jointly controlled operations or assets, under paragraph Aus57.1(c) BHP would need to disclose the aggregate of mine transport equipment included in that line item that relates to jointly controlled operations and assets.

Furthermore, just to be clear, there is no need to separate out the assets relating to "operations" and the other "assets". Under paragraph Aus57.1 "operations and assets" are one amount.

Aus57.2	In respect of interests in jointly controlled entities, the venturer shall disclose 
	the following information:
	(a)	the fair value of interests in jointly controlled entities for which there 
		are published price quotations;
	(b)	where the equity method is applied to interests in jointly controlled entities, 
		summarised financial information of jointly controlled entities, including the 
		aggregate amounts of each of the current assets, long-term assets, current 
		liabilities, long-term liabilities, income and expenses;
	(c)	the reporting date of the financial statements of a jointly controlled entity, 
		when such financial statements are used in applying the equity method and are 
		as of a reporting date or for a period that is different from that of the venturer, 
		and the reason for using a different reporting date or different period;
	(d)	the nature and extent of any significant restrictions (for example, resulting 
		from borrowing arrangements or regulatory requirements) on the ability of jointly 
		controlled entities to transfer funds to the venturer in the form of cash dividends, 
		or repayment of loans or advances; 
	(e)	the unrecognised share of losses of a jointly controlled entity, both for the period 
		and cumulatively, if a venturer has discontinued recognition of its share of losses 
		of a jointly controlled entity;
	(f)	the fact that a jointly controlled entity is not accounted for using the equity 
		method in accordance with paragraph 2; and
	(g)	summarised financial information of jointly controlled entities, either individually 
		or in groups, that are not accounted for using the equity method, including the 
		amounts of total assets, total liabilities, revenues and profit or loss.

Paragraphs in green relate to individual jointly controlled entities.  The remainder are aggregate disclosures.

Use summarised aggregate elements for Joint Ventures and add any new elements not currently in IAS.

Aus57.2 allows for aggregate disclosures for current assets, long-term assets, current liabilities and long-term liabilities. There is no requirement to disclose total assets and total liabilities. We could include them as XBRL-Completeness or AU-IFRS-CP (common practice). The same applies to Aus57.3 for non-equity accounted investments in jointly controlled entities. Noted as an "Unresolved Issue".

(g) may require separate elements for non-equity accounting.

The reference in paragraph Aus57.2(b) to "income and expenses" and in paragraph Aus57.2(g) to "revenues 
and profit or loss" are derived from the previous Australian standard AASB 1006, which said:   

9.4	A venturer must disclose, in a summarised presentation, its share of the joint venture entity's:
(a)	current assets 
(b)	non-current assets 
(c)	current liabilities
(d)	non-current liabilities
(e)	revenues
(f)	expenses
(g)	operating results (profits or losses) before income tax
(h)	income tax expense attributable to operating results (profits or losses)
(i)	extraordinary items (net of income tax).

In this context, AASB interpret "income and expenses" [paragraph Aus57.2(b)] to mean total income, which is 
both revenues and gains, and (separately) total expenses.  The wording change from "revenue" in AASB 1006 
to "income" in AASB 131 is needed because what AASB previously called revenue meant all inflows (AASB didn't 
distinguish revenues and gains), whereas the IASB Framework uses income to mean the total inflows, being 
revenue and gains.

Also, in this context, AASB interpret "revenues" [paragraph Aus57.2(g)] to mean revenue in the IFRS sense, 
being income but not gains. "Profit or loss" [paragraph Aus57.2(g)] AASB interpret as being net profit or 
loss, namely income less expenses.

Aus57.3	The following disclosure shall be made by the venturer:
	(a)	in respect of each significant jointly controlled entity:
		(i)	its name, principal activities and the country of incorporation 
			or residence;
		(ii)	the venturer’s ownership interest as at the jointly controlled 
			entity’s reporting date and, if different, at the venturer’s 
			reporting date;
		(iii)	the proportion of voting power held in the jointly controlled 
			entity where different from the proportion of ownership interest 
			held; and
		(iv)	where a jointly controlled entity holds equity in the venturer, 
			the percentage of equity held by the jointly controlled entity.
	(b)	where the equity method is applied to interests in jointly controlled 
		entities, the amount of the venturer’s share of jointly controlled entities’:
		(i)	profit or loss before income tax; and
		(ii)	income tax expense; and
	(c)	where the equity method is applied to interests in jointly controlled entities:
		(i)	the amount of impairment losses recognised in profit or loss during 
			the period and the line item(s) of the income statement in which those 
			impairment losses are included; and
		(ii)	the amount of reversals of impairment losses recognised in profit or 
			loss during the period and the line item(s) of the income statement in 
			which those impairment losses are reversed; and
	(d)	the venturer’s share of jointly controlled entities’ non-capital expenditure 
		commitments contracted for other than for the supply of inventories.

Paragraphs in green relate to individual jointly controlled entities.  The remainder are aggregate disclosures.

These disclosures are the same as for Investments in Associates.

For (b)(i)

For (c)

This is a movement analysis for Investments in Associates. Most of the elements have a reference of IFRS-CP, which means that the movement analysis not is required under IFRS. The only element to have a specific reference is “Goodwill in Associates Transferred …”.

The two elements of interest are “Impairment, Investments in Associates” and “Reversal of Impairment, Investments in Associates”. These two elements could be copied and edited to relate to Investments in Jointly Controlled Entities. The title of Movement Analysis could be changed to Impairment Disclosures for Jointly Controlled Entities and only include the equivalents of the ones mentioned above with children for the Income Statement Line Items requirements. This may require a tuple for each to allow for multiple lines items.

Do we need to include a movement analysis for Jointly Controlled Entities?

New element in Income Statement Disclosures (see above (b)(i)) – Share of Profit (Loss) from Equity-Accounted Jointly Controlled Entities. AASB advised that not required as part of Share of Profit (Loss) from Equity-Accounted Joint Ventures.

Applies to both Income Statement formats – By Function and By Nature. Not required - see comment above from AASB.

(b) is not covered as there is no breakdown of Income Tax Expense (Income) in the IFRS taxonomy. The detail required could be shown as children of Aggregate Amount of Net Profit (Loss) in Jointly Controlled Entities as the section will follow the Summarised Information of Associates, In Aggregate section shown below:

“The venturer’s share of any discontinued operations of such entities” has an equivalent element in Investments in Associates – Investor’s Share of Discontinued Operations of Associates Accounted for Using Equity Method. It will be automatically included by copying/editing the Investment in Associates section as recommended for Aus57.3.

“The venturer’s share of the profit or loss of such entities” can be inserted by adding element as a child to the element Share of Profit (Loss) from Equity-Accounted Investments (see Aus57.3(b)(i) screen shot) in the Income Statements. AASB advised that not required in Income Statement.

The “carrying amount of those interests” may require an additional element in the equivalent of the Associates element “Summarised Financial Information of Associates, Aggregate (see screen shot below)

Alternative reading of Aus57.5 and a check on the IFRS taxonomy indicates that this paragraph does not require an element. It simply means that the amounts are aggregated with other values in the items mentioned.
