"Given the continued deterioration in the macroeconomic outlook and significant mid- and long-term uncertainty," Royal Dutch Shell (RDS.A, RDS.B) is slashing its quarterly dividend to $0.16, from $0.47 per share, for the first time since WWII. COVID-19 has slammed demand for oil, gas and related products, while crude recorded a historic plunge into negative territory earlier this month. Shell's adjusted current cost of supplies income, used as a proxy for net profit, slid 45% to $2.9B during the first quarter of 2020, compared with $5.3B a year earlier.
