#### Assurant 401(k) Plan

### Notes to Financial Statements

#### December 31, 2024 and 2023
Three different valuation techniques can be used in determining fair value for financial assets: the market, income or cost approaches. The three valuation techniques described in the fair value measurements and disclosures guidance are consistent with generally accepted valuation methodologies. For all the classes of financial assets included in the above hierarchy, the Plan uses the market approach. The market approach valuation techniques use prices and other relevant information generated by market transactions involving identical or comparable assets. When possible, quoted prices (unadjusted) in active markets are used as of the period-end date (such as for mutual funds, money market funds and common stock).

While not all three approaches are applicable to all financial assets, where appropriate, the Plan may use one or more valuation techniques. For the years ended December 31, 2024 and 2023, the application of the valuation technique applied to the Plan’s classes of financial assets has been consistent.

Level 1 Assets :

The Plan’s assets classified as Level 1 as of December 31, 2024 and 2023 consisted of mutual funds, money market funds and common stock that are publicly listed and/or actively traded in an established market.

Level 2 Assets :

The Plan’s assets classified as Level 2 as of December 31, 2024 and 2023 consisted of collective investment trusts established for employee benefit plans. Plan management has determined that the trusts have a readily determinable fair value because the trusts’ fair values are based on the end of day net asset value per unit which is published daily and observable to the Plan and its Participants through Vanguard’s online portal and is the basis for current transactions. The units of the trusts may be redeemed daily and there are no restrictions on redemptions.

The Plan Sponsor evaluates the following factors in order to determine whether the market for a financial asset is inactive. The factors include, but are not limited to:

• whether there are few recent transactions,

• whether little information is released publicly,

• whether the available prices vary significantly over time or among market participants,

• whether the prices are stale (i.e., not current), and

• the magnitude of the bid-ask spread.

Illiquidity did not have an impact in the fair value determination of the Plan’s financial assets as of December 31, 2024 and
