What type of cash advance may require explicit authorization from agency heads?

A special cash advance may require explicit authorization from agency heads due to its unique nature and purpose. Unlike regular cash advances that are generally used for predictable, routine expenses, a special cash advance is often intended for specific projects or purposes that might not fall under the standard budgeting guidelines. Since these advances can involve significant amounts of money or cater to exceptional circumstances, it is critical for agency heads to oversee and authorize them. This level of scrutiny helps ensure financial accountability and proper allocation of resources, aligning with the organization's overall financial management policies.

In contrast, regular, operational, and administrative cash advances typically follow established procedures and may not necessitate the same degree of oversight as special cash advances, thus requiring less formal authorization.
