SHHL Redeemable Preferred Shares	15. SHHL Redeemable Preferred Shares In May 2016, the Company issued 10,000,000, 7% SHHL redeemable preferred shares totaling £10 million ($15 million) to unrelated parties. These shares were redeemable by the holders upon an exit, such as an IPO, or sale of the Company and the cumulative dividends are only paid on redemption. As of January 3, 2021, redemption of the preferred shares was not probable. During the second quarter of Fiscal 2021, the Company concluded that the shares were probable of becoming redeemable and, therefore, accreted the shares to their redemption value. The accretion of $5 million is reflected as a reduction in additional paid-in capital on the consolidated statements of changes in redeemable shares and shareholders’ equity (deficit). In addition, the Company remeasured the SHHL redeemable preferred shares and recognized a foreign currency translation gain of $1 million for the fiscal year ended January 2, 2022, which is reflected within accumulated deficit on the consolidated statements of changes in redeemable shares and shareholders’ equity (deficit). The Company redeemed these preferred shares for cash totaling $20 million in July 2021. On March 31, 2021, the Company issued 12,970,766 senior SHHL convertible preference shares (the “Senior Preference Shares”) in an aggregate liquidation preference of $175 million, or approximately $13.49 per Senior Preference Share (the “Issuance Price”), to certain funds managed, sponsored or advised by Goldman Sachs & Co. LLC or its affiliates (the “Preference Share Investors”). The Company received net proceeds of $162 million and incurred transaction costs of $13 million related to the Senior Preference Shares. The Senior Preference Shares accrue a non-cash dividend of 8% per annum on the investment amount of the Senior Preference Shares plus all previously compounded non-cash dividends. The Senior Preference Shares were initially presented as mezzanine equity due to the existence of certain redemption options.

In addition, the Company recognized a deemed dividend of $51 million in connection with the conversion of the Senior Preference Shares into Class A common stock, because the conversion was effected at a discount to the public offering price.
