Our partnership settles the difference between the contracted fixed and floating rates of its interest rate swaps on a net basis. All interest rate swap contracts exchanging floating rate interest amounts for fixed rate interest amounts are designated as cash flow hedges in order to reduce our partnership’s cash flow exposure resulting from variable interest rates on borrowings. The interest rate swaps and the interest payments on the borrowings occur simultaneously and the amount accumulated in equity is reclassified to profit or loss over the period that the floating rate interest payments on borrowings affect profit or loss.
