EQT Partners Inc., the Company’s manager, has determined that market participants would take these inputs into account when valuing the investments.

(2) Inputs are weighted based on fair value of the investments included in the range.

(3) Inputs include unlevered discount rate for certain Infrastructure Assets.

 

The Manager is ultimately responsible for our net asset value calculations.

 

Valuations involve subjective judgments and may not accurately reflect realizable value. The assumptions above are determined by the Manager and reviewed by our independent valuation advisor. A change in these assumptions or factors would impact the calculation of the value of our assets. For example, assuming all other factors remain unchanged, the changes listed below would result in the following effects on our asset values as of March 31, 2026.:
