Db74, You are correct to claim the audit exemption a company must be covered By the Companies (Amendment) Act 1986. The Act does not apply to S2(1) (a) a company not trading for the acquisition of gain by the members.
A non for profit will have clauses in its memo and arts specifically dealing with the objectives, ongoing reward of members ie dividends, division of assets on winding up. It will state that dividends are not to be paid to members and that the assets are to be passed to a similar organisation on winding up and not to the members. The members get nothing from their interest in the company.
Look at this section in terms of a property management company. The members pool their resources to manage the insurance, common areas maintenance, refuse collection ect. If the members went as individuals to obtain services on their own, I imagine that the total costs would end up being more. Can this be considered to be "the gain of members" I would argue that it is for the benefit of members and members alone. Then consider the term trading. Is the collection of service charges and the engagement of service providers considered to be economic activity ie trading again I would argue that it is.
But it is a matter of interpretation and other may take a different view of a company ltd by shares and the operation of a mgt co.
I am not a legal expert but take the view that if say Concern was a company ltd by shares it clearly would not qualify for the audit exemption as the company is not set up for the gain of members it has a much wider remit. The members with the directors are effectively the custodians of the assets on behalf of the community being assisted not the members.
