I used the word "enterprise" because I could not think of a better one. My intention was to convey that it might be either a business or individual.
In the case of a business, a reasonably high standard of completeness is usually expected -- for example, all creditors and debtors should be listed, not just the major ones.
Banks usually do not usually require the same level of precision on individuals; a summary statement of major assets and liabilities is considered sufficient. Strictly speaking, that is not a statement of affairs as an accountant might use the expression, but people do at always use language in its strictest sense.
