(1)			Give-up fees as well as cash and voice brokerage revenues are excluded from the calculation of listed derivatives, average rate per contract.
(2)			Interest income related to securities lending is excluded from the calculation of Securities RPM.
(3)			The ADV for the three months ended March 31, 2021 includes the ADV of Gain Capital Holdings, Inc. (“Gain”), which was acquired effective August 1, 2020.

Operating Revenues

Operating revenues increased $104.6 million, or 29%, to $471.4 million in the three months ended March 31, 2021 compared to $366.8 million in the three months ended March 31, 2020.

The table above displays operating revenues disaggregated across the key products we provide to our clients. Operating revenues in listed derivatives increased $3.0 million, or 3%, to $101.1 million in the three months ended March 31, 2021. This growth was primarily driven by a 36% increase in the average rate per contract, which was partially offset by a 22% decline in listed derivative contract volumes.

Operating revenues in OTC derivatives declined $9.4 million, or 21%, to $35.1 million in the three months ended March 31, 2021, primarily driven by a 23% decline in the average rate per contract as the comparative prior year period benefited from a widening of spreads due to heightened volatility in energy markets driven by the onset of the COVID-19 pandemic.

Operating revenue from securities transactions increased $26.8 million, or 20%, to $157.8 million in the three months ended March 31, 2021, primarily as a result of continued heightened volatility in global equity and fixed income markets, an expansion of our product offering and growth in market share in our Institutional segment.

Operating revenues from FX/CFD contracts increased $65.8 million, to $74.7 million in the three months ended March 31, 2021, as a result of an incremental $71.2 million in retail FX/CFD contracts operating revenues resulting from the acquisition of Gain Capital Holdings, Inc. (“Gain”) which was partially offset by lower FX operating revenues in our legacy FX prime brokerage business.

Operating revenues from global payments increased $4.0 million, or 14%, to $32.8 million in the three months ended March 31, 2021, as a result of an 8% increase in Rate per Million (“RPM”) and an 8% increase in the ADV.

Operating revenues from physical contracts increased $25.7 million, or 108%, to $49.5 million in the three months ended March 31, 2021, primarily due to continued strong customer demand for precious metals as well as increased activity in biodiesel feedstock markets. The three months ended March 31, 2021 include a $2.5 million net gain recognized on the sale of inventory carried at the lower of cost or net realizable value at the end of the first quarter of fiscal 2021.

Interest and fee income earned on client balances, which is associated with our listed and OTC derivative, correspondent clearing, and independent wealth management product offerings, declined $9.5 million, or 62%, to $5.8 million in the three months ended March 31, 2021, primarily as a result of a significant decline in short term interest rates related to FOMC actions to reduce the federal funds rate in March 2020. Partially offsetting the decline in short term interest rates was an increase in average client equity and average FDIC sweep client balances of 56% and 42%, respectively.

Following the acquisition of Gain and in advance of the planned merger of the operations of Gain’s U.K. domiciled subsidiaries into StoneX Financial Ltd., a U.S. dollar denominated entity, we enacted a plan to mitigate our exposure to the British Pound in the Gain subsidiaries. As part of this plan, we increased the U.S. dollar balances in the Gain subsidiaries and also utilized derivative transactions to mitigate the remaining British Pound exposure. During the three months ended March 31, 2021, we completed the transfer of the majority of the operations of Gain’s U.K. domiciled subsidiaries into StoneX Financial Ltd. and subsequently closed out our derivative transactions, realizing a $1.2 million loss on the derivative positions and an offsetting $3.1 million foreign currency gain on revaluation for the three months ended March 31, 2021. Each of these items is reflected in operating revenues in the Corporate Unallocated segment. Prior to the transfer, the assets and liabilities of Gain’s U.K. subsidiaries were subject to translation to the U.S. dollar, and for the three months ended March 31, 2021, the foreign currency translation adjustment related to Gain’s U.K. subsidiaries resulted in a $1.5 million increase included within “accumulated other comprehensive income”.

Our variable expenses include variable compensation paid to traders and risk management consultants, bonuses paid to operational, administrative, and executive employees, transaction-based clearing expenses and introducing broker commissions. We seek to make non-interest expenses variable to the greatest extent possible, and to keep our fixed costs as low as possible.

As a percentage of total non-interest expenses, variable expenses were 60% in the three months ended March 31, 2021 compared to 63% in the three months ended March 31, 2020. During the three months ended March 31, 2021, non-variable expenses, excluding bad debts increased $50.7 million, or 51%, period-over-period, of which $33.5 million of the increase related to companies acquired after March 2020.
