As has been stated, the foregoing realised profits test applies to both private and public companies, but public companies face an additional test in relation to distributions, in that s.BFD requires that any distribution must not reduce the value of the company’s net assets below the aggregate of its total called up share capital plus any undistributable reserves. The effect of this rule is that public companies have to account for changes in the value of their fixed (non-current) assets, and are required to apply an essentially balance sheet approach to the determination of profits.
