According to IAS 28:17
Then IAS27:8 says: “An entity that is exempted in accordance with paragraph 4(a) of IFRS 10 from consolidation or paragraph 17 of IAS 28 (as amended in 2011) from applying the equity method may present separate financial statements as its only financial statements.“An entity need not apply the equity method to its investment in an associate or a joint venture if the entity is a parent that is exempt from preparing consolidated financial statements by the scope exception in paragraph 4(a) of IFRS 10 or if all the following apply:
(a) The entity is a wholly-owned subsidiary, or is a partially-owned subsidiary of another entity and its other owners, including those not otherwise entitled to vote, have been informed about, and do not object to, the entity not applying the equity method.
(b) The entity’s debt or equity instruments are not traded in a public market (a domestic or foreign stock exchange or an over-the-counter market, including local and regional markets).
(c) The entity did not file, nor is it in the process of filing, its financial statements with a securities commission or other regulatory organisation, for the purpose of issuing any class of instruments in a public market.
(d) The ultimate or any intermediate parent of the entity produces financial statements available for public use that comply with IFRS, in which subsidiaries are consolidated or are measured at fair value through profit or loss in accordance with IFRS 10.
AND finally: IAS 27:10
My question is: if my company ticks off all of the points under IAS 28:17 and I choose to account for my associates in accordance with IFRS 9, what does my Parent (we're 100% subsidiary) need to do? Would it need to apply the equity method for any associates, i.e. would they need to make an adjustment to reverse out my IFRS 9 treatment and replace it with the equity method accounting?When an entity prepares separate financial statements, it shall account for investments in subsidiaries, joint ventures and associates either:
(a) At cost;
(b) In accordance with IFRS 9; or
(c) Using the equity method as described in IAS 28
