@SheamusPatt @ChrisMayLA6 Was having a similar conversation about where the "blame" lies for this and I do wonder if there is a role for auditors and accounting standards to spot when borrowing to pay dividends becomes unsustainable. Setting aside Thames Water for the moment, it does seem from large corporate failures of recent years it is a strong indicator if they are borrowing to pay dividends for more than a couple of years and without a particular plan to return to profit and sustainable dividends, that they are headed for disaster! I suspect it doesn't happen as much with fully listed companies. All the ones I'm thinking of (BHS, Wilko, Thomas Cook, Thames Water and co) have been effectively either private or private equity owned.
Also, I think the figures look even worse if you confine your time window to after the McQuarrie/PE takeover of Thames Water. RWE had other ways of extracting value (like keeping the TW international businesses) but weren't so much financial engineering.
