Indeed there is very little. Just some mumble mouthing about "intentions."
""But unlike those exchanges, ultimately our intention is that when companies list shares on LTSE for sale to the public, they will adopt a set of governing practices that are designed to help them build lasting businesses and empower long term-focused shareholders.""
Utterly indistinguishable from the Wooden Language heard from every such grandee.
I am not one to indulge the sort of naivety that might allow me to pretend that powerful investors are going to tolerate any more impediments to their desires than legally required, or at least enforceable, so unless there are concrete differences imposed by SEC et al. I expect this is -- or eventually will be -- simply Wall Street West.
