Notes on the numbers above: House value estimates are approximate. I don't have a way to check NT's UK pensions or flat value, so their values stay static for the purpose of this update (unless I happen to get some info by chance). UK asset values and debt amounts are calculated figuring $1.60 for every British pound.
