Effective Income Tax Rate

Our provision for income taxes may not have the customary relationship of taxes to income. A reconciliation between the income tax provision at the U.S. corporate income tax rate and the income tax expense (benefit) at the effective income tax rate was as follows:

Unrecognized Tax Benefits

​

During the second quarter 2025, we recognized a $5.4 million tax benefit upon releasing an unrecognized tax benefit (“UTB”) at the 35% federal rate in force before the Tax Cuts and Jobs Act of 2017 (“TCJA”). The UTB was previously remeasured to the current U.S. tax rate of 21% upon enactment of TCJA.

​

Recent Change in Tax Legislation

​

On July 4, 2025, the United States enacted Public Law 119-21. The accounting consequences of a change in tax law are required to be recognized in the period legislation is enacted. Generally, a company is also required to consider the impact of new tax law on realizability of deferred tax assets (“DTAs”), including determination of whether a change in valuation allowance is necessary. The second quarter 2025 financial statements do not reflect the impacts of Public Law 119-21 because the enactment date does not fall within the reporting period. At this time, a reasonable estimate of the future impacts of the legislation cannot be made.

​

Pillar Two Model Rules

​

We are currently monitoring global enactments of the Pillar Two model rules proposed by the Organisation for Economic Co-operation and Development, which brings forward a 15% global minimum tax. Generally, a company is required to consider the impact of new tax law on realizability of its DTAs, including determination of whether a change to its valuation allowance amounts is necessary. We made an accounting policy election to disregard the Pillar Two model rules when evaluating DTAs and rather recognize a current period tax expense when incurred.
