Which of the following is not a verifiable cost that would appear on the operating statement?

Contract rent is not a verifiable cost that would typically appear on the operating statement because it often involves subjective considerations and negotiated terms between parties, rather than being strictly measurable and definite. Verifiable costs are those that can be confirmed through documentation and receipts, providing an undeniable basis for their existence and amount.

In contrast, insurance, management fees, and repairs are all quantifiable costs that can be easily documented through invoices or contracts, allowing for clear verification of the amounts incurred. Since contract rent can vary significantly based on individual negotiation and may include various escalations or conditions that are not easily defined, it does not fit into the category of verifiable costs in the same way as the others listed.
