Schedule of Reconciliation of Benefit from (Provision for) Income Taxes

A reconciliation of the provision for income taxes with amounts determined by applying the statutory U.S. federal income tax rate to income before income taxes is as follows:

									For the Year Ended December 31,
															2025									2024									2023
Pre-Tax Net Book Income (“NBI”)															$	5,899								$	6,035								$	5,701
Income tax provision at the U.S. federal income tax rate															(1,239)			(21.0)		%				(1,267)			(21.0)		%				(1,197)			(21.0)		%
Reduction (increase) in provision for income taxes resulting from:
Partnership income not subject to federal income tax															1,220			20.7		%				1,250			20.7		%				1,181			20.7		%
Texas Margin Tax (1)															(3)			(0.1)		%				(44)			(0.7)		%				(49)			(0.9)		%
Change in valuation allowance (2)															–			–		%				–			–		%				22			0.4		%
Other															(1)			–		%				(4)			(0.1)		%				(1)			–		%
Provision for income taxes															$	(23)		(0.4)		%				$	(65)		(1.1)		%				$	(44)		(0.8)		%
Effective income tax rate															(0.4)		%							(1.1)		%							(0.8)		%

(1)Although the Texas Margin Tax is not considered a state income tax, it has the characteristics of an income tax since it is determined by applying a tax rate to a base that considers our Texas-sourced revenues and expenses.

(2)During 2023, management concluded that it is more likely than not that the deferred tax assets attributable to OTA will be fully realizable. As a result, for the year-end December 31, 2023, we recorded a full release of the valuation allowance against OTA’s deferred tax assets.
