Total taxes were $9.3 billion for the first quarter, a decrease of $1.4 billion from the prior year, with income tax expense of $2.5 billion versus $3.6 billion previously. The effective income tax rate was 40%, up 6 percentage points from the prior-year period; management attributes the rate increase to portfolio mix effects impacted by derivative mark‑to‑market losses. Total other taxes and duties were $6.8 billion for the quarter. The higher effective tax rate and the changes in tax expense materially affected quarterly after‑tax earnings.
