Details of the proposal can be found in an SC 13D/A; following statements of ownership which (IMO) is not the proper form. IMO it should instead be provided in an 8K.
How much equity does ESL have? Oddly that is not clear to me. One figure that does make sense is the O/S count; shown repeatedly on the 13D as "Shared Dispositive Power": 103,424,909 shares. How much ESL/RBS/JPP have varies based on the terminology and footnotes used in various sections of the 13D... Readers must interpret the share counts.
For example the 1st Section shows ESL Partners "Beneficially" owns 153 million of the 103 million O/S which represents a 73.7% equity stake; with footnotes elaborating how the figures are derived.
