Non-exchange revenues are those in which a government gives or receives value without directly receiving or giving equal value in return. Sales taxes are a classic example of a non-exchange revenue because the payer (consumer) does not receive a direct, measurable benefit from the government in exchange for the tax paid.
Other examples of non-exchange revenues include property taxes, grants, and fines. In contrast, licensing fees and investment earnings are exchange or exchange-like revenues, since they involve a mutual benefit or earnings return.

First, we calculate total eligible project costs:
Eligible categories (architectural, construction, project management):
Architectural (actual): $90,000
Construction (actual): $10,000,000
Project management (city employee at 50% time for 6 months):
$10,000/month × 6 months × 50% = $30,000
Total eligible cost = $90,000 + $10,000,000 + $30,000 = $10,120,000
State reimburses 40% of eligible cost:
0.40 × $10,120,000 = $4,048,000

The Governmental Accounting Standards Board (GASB) issues accounting standards after a structured due process that includes:
Publication of a Discussion Document (e.g., Preliminary Views)

A majority vote (not unanimous) of the GASB board members is required to approve and issue a final standard.
