(1) Fair value is generally determined through appraisals of the underlying collateral. The Company may also use another available source of collateral assessment, such as purchase offers, letters of intent, or broker price opinions, to determine a reasonable estimate of the fair value of the collateral.

(2) Due to the uncertainty in the movement of the conversion rate, the current conversion rate as of the respective consolidated balance sheet dates was utilized in the fair value calculation.

(3) The expected term was based on an August 2024 claim filing deadline and subsequent period for claims to be processed. As such, a range is not meaningful to disclose.

(4) The growth rate was based on the arithmetic average of analyst price targets.

(5) The expected term was based on a May 2024 claim filing deadline. As such, a range is not meaningful to disclose.
