Gross margins on gaming operations totaled 62% versus 59% in the prior year quarter. Margins in the current period were favorably impacted by reduced jackpot-related expense, as well as the property damage portion of the Gulf Coast insurance settlement of us$ 5 million, before tax.
For the six-month period, revenues and gross profit totaled us$ 666 million and us$ 397.7 million, respectively, compared to us$ 602.9 million and us$ 349.4 million in the prior year period. Year-over-year improvement was attributed to the growth and enhanced performance of our installed base.
The installed base of recurring revenue machines ended the quarter at a record 54,800 units, an increase of 10,400 units from the prior year quarter and 1,700 units from the immediately preceding quarter. Growth was primarily the result of incremental lease operations placements in Mexico, New York, Delaware and Rhode Island and incremental casino operations placements in Oklahoma, California and Florida.
