[1] The impact of transitioning to IFRS 9 at 1 January 2018 on the consolidated financial statements of HSBC was a decrease in net assets of $1.6bn, arising from a decrease of $2.2bn from additional impairment allowances, a decrease of $0.9bn from our associates reducing their net assets, an increase of $1.1bn from the remeasurement of financial assets and liabilities as a consequence of classification changes and an increase in net deferred tax assets of $0.4bn.

[2] The $350m at 31 December 2017 represents the IAS 39 available-for-sale fair value reserve as at 31 December 2017.

[3] At 31 December 2019, retained earnings included 432,108,782 treasury shares (2018: 379,926,645; 2017: 360,590,019). In addition, treasury shares are also held within HSBC’s Insurance business retirement funds for the benefit of policyholders or beneficiaries within employee trusts for the settlement of shares expected to be delivered under employee share schemes or bonus plans, and the market-making activities in Global Markets.

[4] Cumulative goodwill amounting to $5,138m has been charged against reserves in respect of acquisitions of subsidiaries prior to 1 January 1998, including $3,469m charged against the merger reserve arising on the acquisition of HSBC Bank plc.
