Dispositions	Note 2 — Dispositions On February 3, 2022, we announced the strategic decision to sell our 97%-owned Quantitative Equities subsidiary, Intech Investment Management LLC (“Intech”), to a consortium composed of Intech management and certain Intech non-executive directors (“Management Buyout”). The Management Buyout is expected to enable both organizations to refocus on their key value propositions: Janus Henderson on providing active, fundamental investing, and Intech on delivering quantitative investment solutions for institutional investors. On March 31, 2022, the Management Buyout closed and we recognized a $9.1 million loss on disposal of Intech. The loss is recognized in other non-operating expenses, net on our Condensed Consolidated Statements of Comprehensive Income. Consideration received as part of the Management Buyout included cash proceeds of $14.9 million ($9.9 million will be collected in the third quarter 2022); contingent consideration of up to $17.5 million, which is based on future Intech revenue; and an option agreement with a fair value of $3.9 million that provides JHG the option to purchase a certain equity stake in Intech at a predetermined price on or before the seventh anniversary of the Management Buyout. The terms of the transaction also included a $20.0 million seven-year JHG and Intech entered into a transition services agreement that provides for continuation of support services to help ensure a seamless transition in operations and continuity in serving Intech’s clients.

As of June 30, 2022, and December 31, 2021, the fair value of securities sold but not yet purchased was $0.5 million and $3.1 million, respectively. The cash received from the short sale and the obligation to repurchase the shares are classified in other current assets and accounts payable and accrued liabilities on our Condensed Consolidated Balance Sheets, respectively. Fair value adjustments are recognized in investment gains (losses), net on our Condensed Consolidated Statements of Comprehensive Income. Derivative Instruments in Consolidated Seeded Investment Products Certain of our consolidated seeded investment products utilize derivative instruments to contribute to the achievement of defined investment objectives.

Level 1 Fair Value Measurements Our Level 1 fair value measurements consist mostly of investments held by seeded investment products, investments in advised mutual funds, cash equivalents, securities sold, not yet purchased, and investments related to deferred compensation plans with quoted market prices in active markets. The fair value level of consolidated investments held by seeded investment products is determined by the underlying securities of the product. The fair value level of unconsolidated investments held in seeded investment products is determined by the net asset value (“NAV”), which is considered a quoted price in an active market. Level 2 Fair Value Measurements Our Level 2 fair value measurements consist mostly of consolidated seeded investment products, derivative instruments, and our long-term debt. The fair value of consolidated seeded investment products is determined by the underlying securities of the product. The fair value of our long-term debt is determined using broker quotes and recent trading activity, which are considered Level 2 inputs. Level 3 Fair Value Measurements Investment Securities As of June 30, 2022, and December 31, 2021, certain securities within consolidated VIEs were valued using significant unobservable inputs, resulting in Level 3 classification. Intech Option Agreement and Contingent Consideration On March 31, 2022, we completed the sale of Intech. Consideration received as part of the Management Buyout included contingent consideration of up to $17.5 million and an option agreement that provides JHG the option to purchase a certain equity stake in Intech at a predetermined price on or before the seventh anniversary of the Management Buyout. As of June 30, 2022, the fair value of the option agreement and of the Intech contingent consideration was $3.1 million and $12.3 million, respectively. Significant unobservable inputs were used to value the call option and contingent consideration, including revenue estimates, discount rate, and volatility. Deferred Bonuses Deferred bonuses represent liabilities to employees over the vesting period that will be settled by investments in our products. The significant unobservable inputs used to value the liabilities are investment designations and vesting periods. Changes in Fair Value Changes in fair value of our Level 3 assets for the three and six months ended June 30, 2022 and 2021, were as follows (in millions): Three months ended Six months ended June 30, June 30, 2022 2021 2022 2021 Beginning of period fair value $ 23.2 $ 27.2 $ 8.8 $ 31.4 Intech option agreement (0.8) — 3.1 — Contingent consideration from sale of Intech (0.3) — 12.3 — Settlement of contingent consideration — (1.8) — (4.0) Fair value adjustments (0.3) 1.4 (1.8) (2.5) Transfers from Level 1 0.5 — 0.5 — Transfers to Level 1 (2.1) — (2.1) — Purchases of securities 1.2 0.4 1.0 2.7 Sales of securities — (0.7) (0.3) (1.1) Foreign currency translation (0.3) — (0.4) — End of period fair value $ 21.1 $ 26.5 $ 21.1 $ 26.5 Changes in fair value of our individual Level 3 liabilities for the three and six months ended June 30, 2022 and 2021, were as follows (in millions): Three months ended June 30, Six months ended June 30, 2022 2021 2022 2021 Deferred Deferred Deferred Deferred bonuses bonuses bonuses bonuses Beginning of period fair value $ 34.3 $ 73.6 $ 50.5 $ 65.2 Fair value adjustments (1.0) 2.0 (2.6) 4.3 Vesting of deferred bonuses (14.4) (48.2) (36.0) (50.7) Amortization of deferred bonuses 10.8 8.1 19.2 16.1 Foreign currency translation (2.1) 0.1 (3.5) 0.7 End of period fair value $ 27.6 $ 35.6 $ 27.6 $ 35.6 Nonrecurring Fair Value Measurements Nonrecurring Level 3 fair value measurements include goodwill and intangible assets. We measure the fair value of goodwill and intangible assets on initial recognition using discounted cash flow (“DCF”) analysis that requires assumptions regarding projected future earnings and discount rates. Because of the significance of the unobservable inputs in the fair value measurements of these assets, such measurements are classified as Level 3.

As part of this disposition, we removed $4.7 million and $40.1 million of trademarks and client relationships, respectively, from our Condensed Consolidated Balance Sheets as these intangible assets were directly connected to Intech. In addition, we also allocated a certain amount of goodwill to Intech, which was also removed from our Condensed Consolidated Balance Sheets as part of the Management Buyout. Out-of-Period Incremental Goodwill Impairment In the first quarter 2020, due to the sudden decline of the global financial markets impacting our assets under management (“AUM”), we recognized a $123.5 million goodwill impairment expense. Subsequent to the first quarter 2020, we identified a $32.8 million error in which we did not consider the incremental impairment charge related to the tax-deductible goodwill. We have corrected this error in the first quarter 2022 as an out-of-period adjustment, which is reflected in the table above and recorded in goodwill and intangible asset impairment charges on our Condensed Consolidated Statements of Comprehensive Income. Future Amortization Expected future amortization expense related to client relationships is summarized below (in millions): Future amortization Amount 2022 (remainder of year) $ 1.3 2023 2.3 2024 1.0 2025 1.0 2026 1.0 Thereafter 10.9 Total $ 17.5

The 2025 Senior Notes include unamortized debt premium, net at June 30, 2022, of $8.9 million, which will be amortized over the remaining life of the notes. The unamortized debt premium is recorded as a liability within long-term debt on our Condensed Consolidated Balance Sheets. JHG fully and unconditionally guarantees the obligations of Janus Henderson US (Holdings) Inc. in relation to the 2025 Senior Notes. Credit Facility At June 30, 2022, we had a $200 million, unsecured, revolving credit facility (“Credit Facility”). JHG and its subsidiaries may use the Credit Facility for general corporate purposes. The rate of interest for each interest period is the aggregate of the applicable margin, which is based on our long-term credit rating and the Secured Overnight Financing Rate (“SOFR”) in relation to any loan in U.S. dollars (“USD”); the Sterling Overnight Index Average (“SONIA”) in relation to any loan in British pounds (“GBP”); the Euro Interbank Offered Rate (“EURIBOR”) in relation to any loan in euros (“EUR”); or the Bank Bill Swap Rate (“BBSW”) in relation to any loan in Australian dollars (“AUD”). As a result of the phase-out of the London Interbank Offered Rate (“LIBOR”), our Credit Facility was amended to incorporate the SOFR as the successor rate to USD LIBOR and the SONIA as the successor rate to GBP LIBOR. We are required to pay a quarterly commitment fee on any unused portion of the Credit Facility, which is also based on our long-term credit rating. Under the Credit Facility, our financing leverage ratio cannot exceed 3.00x EBITDA. At June 30, 2022, we were in compliance with all covenants contained in, and there were no outstanding borrowings under, the Credit Facility. The maturity date of the Credit Facility is February 16, 2024.

As of June 30, 2022, we had $18.2 million of unrecognized tax benefits held for uncertain tax positions. We estimate that the existing liability for uncertain tax positions could decrease by up to $2.3 million within the next 12 months, without giving effect to changes in foreign currency translation.

Redeemable noncontrolling interests in consolidated seeded investment products may fluctuate from period to period and are impacted by changes in our relative ownership, changes in the amount of third-party investment in seeded products and volatility in the market value of the seeded products’ underlying securities. Third-party redemption of investments in any particular seeded product is redeemed from the respective product’s net assets and cannot be redeemed from the assets of our other seeded products or from our other assets. As of June 30, 2022, our ownership percentage in a certain seeded investment product was greater than our VIE consolidation threshold, resulting in the consolidation of the fund, and is the primary driver of the significant increase in our redeemable noncontrolling interests balance.
