Fair Value of Debt

The following table summarizes the aggregate principal amount outstanding under the Company’s debt arrangements and the corresponding estimate of fair value as of June 30, 2025 and December 31, 2024.

The applicable fair value guidance establishes a three tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The fair value of the Company’s debt is based on Level 3 inputs.
