New accounting standards:

Improvements to Income Tax Disclosures

In December 2023, the FASB issued Accounting Standards Update 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" ("ASU 2023-09"). ASU 2023-09 is intended to improve the effectiveness of income tax disclosures by requiring, among other things, the disclosure on an annual basis of: (i) specific categories in the rate reconciliation; and (ii) additional information for reconciling items that meet a quantitative threshold. In addition, ASU 2023-09 requires disclosure (on an annual basis) of the following information about income taxes paid: (i) the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; and (ii) the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received). ASU 2023-09 was effective for annual periods beginning January 1, 2025, to be applied prospectively with an option for retrospective application (with early adoption permitted). The adoption of ASU 2023-09 modified our disclosures but did not have an impact on our financial position or results of operations.

ASU 2024-03, Disaggregation of Income Statement Expenses: Income Statement - Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses and Related Amendment

The amendments in this update require the disclosure of disaggregation of certain income statement expense line items. Specifically, the guidance requires the disclosure of additional information related to certain expenses, including employee compensation, depreciation and amortization, and certain other expenses included in each income statement line item. The amendments also require the disclosure of both the total amount of selling expenses and a definition of selling expenses.

We will adopt this update effective for the annual period beginning January 1, 2027, and interim periods beginning January 1, 2028. The adoption of this update is permitted on a prospective basis or a retrospective basis. The adoption of this update will expand our disclosures but will not have an impact on our financial position or results of operations.

ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software: Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40)

The amendments in this update modernize the recognition framework for the capitalization of internal-use software and remove all references to software development project stages. The guidance requires software development costs to be capitalized when both of the following criteria are met: (i) management has authorized and committed to funding the project, and (ii) it is probable that the project will be completed and the software will be used to perform its intended function. Additionally, the update aligns disclosure requirements for capitalized software costs with those under ASC 360-10, “Property, Plant, and Equipment.”

The amendments in this update are effective for annual reporting periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption of this update is permitted as of the beginning of an annual reporting period. Adoption of this update is permitted on a prospective, retrospective, or a modified retrospective basis. We are currently evaluating the impact the adoption of this update will have on our financial position, results of operations, and disclosures.

Targeted Improvements to the Accounting for Long-Duration Contracts

In August 2018, the FASB issued ASU 2018-12 "Financial Services-Insurance (Topic 944) - Targeted Improvements to the Accounting for Long-Duration Contracts". This update is aimed at improving the Codification related to long-duration contracts, which will improve the timeliness of recognizing changes in the liability for future policy benefits, simplify accounting for certain market-based options, simplify the amortization of deferred acquisition costs, and improve the effectiveness of required disclosures. These updates were originally required to be applied retrospectively to the earliest period presented in the financial statements for periods beginning after December 15, 2020. The FASB subsequently delayed the effective date of ASU 2018-12 to periods beginning after December 15, 2024 for smaller reporting companies, with early adoption permitted.

In December 2022, the FASB issued amendment ASU 2022-05 "Targeted Improvements for Long-Duration Contracts" collectively, “LDTI” that originally required an insurance entity to apply a retrospective transition method as of the beginning of the earliest period presented or the beginning of the prior fiscal year if early adoption was elected. This updated guidance reduces implementation costs and complexity associated with the adoption of targeted improvements in accounting for long-duration contracts that have been derecognized in accordance with ASU 2018-12 before the delayed effective date. Without the amendments in this ASU, an insurance entity would be required to reclassify a portion of gains or losses previously recognized in the sale or disposal of insurance contracts or legal entities because of the adoption of a new accounting standard.

We adopted this guidance effective January 1, 2025, using the modified retrospective approach with changes applied as of January 1, 2024, also referred to as the transition date. The following tables summarize the impacts of the adoption of LDTI on the liability for future policy benefits, deferred acquisition costs, and stockholders' equity as of the transition date as well as impacted historical condensed consolidated financial statement line items for historical comparison.

Impact of the Adoption of LDTI as of the Transition Date:

Stockholders' Equity

The following table summarizes the changes in stockholders' equity due to the adoption of LDTI and the resulting adjusted balances as of January 1, 2024:

										Accumulated
	Number of									Other				Total
	Shares of		Common		Additional		Accumulated			Comprehensive			Shareholders'
	Common Stock		Stock		Paid-in Capital		Deficit			Loss			Equity
Balance at December 31, 2023		7,748,922	$	774,893	$	22,964,490	$	(10,491,934	)	$	(2,916,372	)	$	10,331,077

The increase in accumulated other comprehensive income in our recast of 2024 is driven primarily by the difference between the discount rate applied under the historical accounting method, which was based on an expected investment yield from our current investment strategy, and the single-A discount rate that is required as a part of the adoption of LDTI. The net favorable impact to net loss and accumulated deficit is primarily due to slower amortization of deferred acquisition costs on single pay products.

The following table presents the transition impacts as of January 1, 2024, to the Company's accumulated other comprehensive income (loss) and accumulated deficit as a result of the adoption of LDTI by product type, using the modified retrospective transition method:
