Reconciliation of 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 Three Months Ended March 31,
	2024			2023
Pre-Tax Net Book Income (“NBI”)	$	1,504		$	1,432

Texas Margin Tax (1)		(17	)		(6	)
State income tax provision, net of federal benefit		–			(1	)
Federal income tax provision computed by applying the federal statutory rate to NBI of corporate entities		(3	)		(3	)
Other		(1	)		–
Provision for income taxes	$	(21	)	$	(10	)

Effective income tax rate		(1.4	)%		(0.7	)%

(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.
