(4) A sum is to be regarded as being due to or from the company for the purposes of subsection (2) regardless of whether —(a) the sum is payable at present or in the future; (b) the obligation by virtue of which the sum is payable is certain or contingent; or (c) the sum is fixed or liquidated, or is capable of being ascertained by fixed rules or as a matter of opinion.
