Goodwill Calculation

Hello, This questions asks for the goodwill calculation and I am stuck on the NCI value, I got £120m by doing £400 * 30% but I am not sure if it is right. Any help will be appreciated. Thanks. The question is: Expander plc wishes to acquire a 70% stake in Target plc by purchasing 280 million of Target’s 400 million £1 ordinary shares. Target currently has retained earnings of £1,360 million and is not expecting to issue any shares or pay any dividends in the immediate future. The purchase of Target will be paid for through a combination of immediate and deferred cash payments. Expander will pay £5,000 million of cash at the date of acquisition, plus a further £2,000 million in two years’ time. Target has some valuable brands, trade names and internet domain names. These are not currently recognised in Target’s financial statements. The estimated fair value of these assets is £3,500 million and these brands and domain names are estimated to have a useful life of approximately 8 years. Expander has not yet determined whether it should measure non-controlling interest in its subsidiaries on the basis of a proportionate interest in the identifiable net assets of the subsidiary or whether it should use the “full goodwill” method. The fair value of a 30% holding in Target is estimated to be £2,500 million. Where appropriate you may assume a discount rate of 5% per annum.
