FAQ

What did Assurant (AIZ) executive Ryan Lumsden report in this Form 4?

Ryan Lumsden reported stock-based compensation and related tax withholding. He received common shares from performance share unit vesting and awards, while some shares were withheld to satisfy tax obligations rather than sold in the open market.

How many Assurant (AIZ) shares did Ryan Lumsden acquire in the latest grant?

Ryan Lumsden acquired 2,189 shares from performance share units and 844 additional awarded shares. These grants reflect stock-based compensation, not open-market purchases, and are tied partly to relative performance during Assurant’s 2023–2025 performance cycle.

Why were 1,033 Assurant (AIZ) shares disposed of at $222.15 in this filing?

The 1,033 shares were withheld to cover tax obligations upon the March 16, 2026 vesting of performance share units and restricted stock units. This is a tax-withholding disposition, not a discretionary sale into the market by the executive.

After the reported grants and tax withholding, Ryan Lumsden directly holds 17,855.299 shares of Assurant common stock. This total includes restricted stock units and 42.159 shares acquired through the company’s amended and restated 2004 employee stock purchase plan.

What performance period do the Assurant (AIZ) PSUs in this Form 4 relate to?

The performance share units that vested and generated 2,189 common shares are based on relative performance achieved during Assurant’s 2023–2025 performance cycle. The number of shares issued reflects the company’s performance against the predefined PSU metrics for that period.

Are the Assurant (AIZ) transactions by Ryan Lumsden market buys or sells?

The transactions reflect stock awards and tax withholding, not open-market trades. Shares were granted at no purchase price as compensation, and a portion was automatically withheld to satisfy tax liabilities associated with PSU and restricted stock unit vesting.
