As companies cut dividends in response to the financial havoc caused by the coronavirus, fund managers whose portfolios rely on the payouts are sifting for those most likely to deliver a sustainable yield when the world recovers. Nearly 70 of the top 600 listed companies in Europe cut or suspended dividends between Feb. 24 and March 31, a Reuters analysis found, while 18 of the top 100 London-listed companies have cut or delayed theirs. By March 30, 12 S&P500 firms had reduced or suspended their dividends, according to Goldman Sachs.
