Subsequent Events [Text Block]	22. Subsequent Events: In December 2021, we entered into an additional ASR agreement with Citibank, N.A. to repurchase shares of our common stock for an aggregate purchase price of $100.0 million. Upon payment of the aggregate purchase price on January 4, 2022, we received an initial delivery of 360,913 shares of our common stock, representing approximately $80.0 million of the aggregate purchase price. Upon the final settlement of the ASR agreement in February 2022, we received an additional 141,766 shares, as determined by the volume weighted average share price of our common stock of $198.93 during the term of the ASR agreement. See Note 16. Stockholders' Equity for further discussion. On January 12, 2022, our Board of Directors approved the action to make our environmental health and safety business within the Energy & Specialized Markets segment available for immediate sale at its current fair value. On January 21, 2022, we entered into a stock purchase agreement to sell 3E Company Environmental, Ecological and Engineering ("3E") in exchange for a potential aggregate cash consideration of up to $950.0 million. The purchase price consists of up to $630.0 million of cash consideration paid at closing, subject to customary purchase adjustments, up to $50.0 million of earnout payments based on financial performance in 2023 and 2024, and up to $270.0 million of additional deferred payments based on the buyer's future return on its investment. In January 2022, we granted 608,895 nonqualified stock options, 130,555 shares of restricted stock, and 74,887 PSUs to key employees. The nonqualified stock options and restricted stock have a graded service vesting period of four years. The PSUs granted consisted of 49,533 TSR-based PSUs and 25,354 PSUs that are tied to the achievement of certain financial performance conditions, namely incremental return on invested capital (“ROIC-based PSUs”). Each of the TSR-based PSUs and ROIC-based PSUs have a three-year performance period, subject to the recipients' continued service. The grant date fair value of the ROIC-based PSUs is determined using the closing price of our common stock on the grant date. The related performance condition is driven by the incremental return on invested capital based on net operating profit. The ultimate realization of the PSUs may range from 0% to 200% of the recipient’s target levels established on the grant date. See Note 17. Compensation Plans for further discussion. On February 11, 2022, we acquired 100 percent of the membership interest of Infutor Data Solutions, LLC ("Infutor"), for an aggregate net cash consideration of $223.5 million, of which $1.5 million represents a working capital escrow, plus a contingent earn-out payment of up to $25.0 million subject to the achievement of certain revenue and other performance targets. Infutor, a leading provider of identity resolution and consumer intelligence data, has become a part of the underwriting & rating category within our Insurance segment. We believe this acquisition further enhances Verisk’s marketing solutions offerings to companies across several industries including the insurance industry. On February 16, 2022, our Board of Directors approved a cash dividend of $0.31 per share of common stock issued and outstanding, payable on March 31, 2022, to holders of record as of March 15, 2022. Our Board of Directors also approved an additional share repurchase authorization of $1,000.0 million. On February 16, 2022, our Board of Directors approved the action to make our financial services business within the Financial Services segment available for immediate sale at its current fair value. On February 21, 2022, we entered into a stock purchase agreement to sell our financial services business to TransUnion, a global information and insights company, for $515.0 million in cash consideration paid at closing. This transaction is subject to customary closing conditions, including regulatory approvals and working capital adjustments.
