We use a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon tax authority examination, including resolution of related appeals or litigation processes, if any.

The allocation of the purchase price requires management to make significant estimates in determining the fair values of assets acquired and liabilities assumed, especially with respect to the solar energy systems acquired as part of our acquisition of Vivint Solar in 2020. Significant estimates in valuing certain tangible assets include but are not limited to discount rates.
Any residual purchase price is recorded as goodwill.

The allocation of the economic benefits between us and the fund investor and the corresponding accounting treatment varies depending on the structure of the investment fund.

The allocation of the economic benefits between us and the fund investor and the corresponding accounting treatment varies depending on the structure of the investment fund. 59 We currently utilize the legal structure for our investment funds which we refer to as partnership flips.

We believe that policies associated with our principles of consolidation, revenue recognition, goodwill, impairment of long-lived assets, provision for income taxes, business combinations and calculation of noncontrolling interests and redeemable noncontrolling interests have the greatest impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.
For further information on all of our significant accounting policies, see Note 2, Summary of Significant Accounting Policies , to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. 63 We believe that policies associated with our principles of consolidation, revenue recognition, impairment of long-lived assets, provision for income taxes, business combinations and calculation of noncontrolling interests and redeemable noncontrolling interests have the greatest impact on our consolidated financial statements.
If redemption is at our option or the consolidated joint ventures are not redeemable, we record the investor’s interest as a noncontrolling interest and account for the interest using the HLBV method.
If redemption is at our option, we record the investor’s interest as a noncontrolling interest and account for the interest using the hypothetical liquidation at book value (“HLBV”) method.

We reflect pass-through financing obligations on our consolidated balance sheet as a pass-through financing obligation. We record the investor’s interest in partnership flips or JV inverted leases (which we define collectively as “consolidated joint ventures”) as noncontrolling interests or redeemable noncontrolling interests. These consolidated joint ventures are usually redeemable at our option and, in certain cases, at the investor’s option.
In Q4 2024, we retired our last pass-through financing obligation fund. We record the investor’s interest in partnership flips as noncontrolling interests or redeemable noncontrolling interests. These partnership flips are usually redeemable at our option and, in certain cases, at the investor’s option.
The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Our policy is to include interest and penalties related to unrecognized tax benefits, if any, within the provision for taxes in the consolidated statements of operations.
