When is a company an associate?

Bellss

Hello,

From reading FRS 102 (section 1A) I understand an associate company to be defined as an entity that the investor has significant influence over (that is neither a subsidiary nor an interest in a joint venture). Significant influence is the power to participate in the financial and operating policy decisions of the associate but is not control or joint control over those policies. If an investor holds, directly or indirectly, 20 per cent or more of the voting power of an associate, it is presumed that the investor has significant influence (unless they demonstrate otherwise).

My question is - if a shareholder held 50% voting shares in Company A and this shareholder also held 20% voting shares in Company B (and the shareholder had significant influence in both companies), would company A and B then be associated? If they are associated are any debtor / creditor balances between the two companies (including trade debtors / creditors) to be shown in the debtor / creditor note as 'Associate Amounts falling due within one year ...etc' instead of shown as say 'trade debtors / creditors' in the note?

Many Thanks in advance.
