The decrease was mostly due to VALE paying out their March 2020 dividend in August 2020 because of covid and their dam problems. We also had CIM pay out in July this year where in 2020 the payment came in August. On the positive side, we had increases in payments from OHI, T, ABBV, AOS, and TXN. Plus new August payments from BMY and VZ.
As noted throughout our posts this year, we expect the year over year percentages to vary wildly from month to month as the pandemic threw off the typical months a bunch of our companies payout.
