The increase in the effective tax rate for the three and six months ended March 31, 2024, when compared to the three and six month periods ended March 31, 2023, were primarily attributable to the increases in pre-tax book income from the gain on the divestiture of the U.S. Lawns subsidiary as well as the distribution of pre-tax earnings across legal entities.
