Company-operated restaurant operating profit (“ROP”) was $3.3 million at 17.7% of sales, compared to $2.2 million at 16.3% of sales last year. The improvement in ROP margin was primarily attributable to lower commodity costs and increased leverage on occupancy and other expenses.General and administrative expenses were $16.2 million, or 2.8% of system-wide sales, compared to $14.7 million, or 2.9% of system-wide sales in 2012. The $1.5 million increase was primarily attributable to an increase in domestic franchisee restaurant support services and assessments, and an increase in performance-based incentive compensation expense. Through the end of the third quarter, Operating EBITDA was $51.2 million at 32.5% of total revenues, compared to $40.9 million at 31.2% of total revenues, in 2012. The 130 basis point increase in Operating EBITDA was primarily due to strong same-store sales increases, one-time franchise fees associated with the conversion of the restaurants in Minnesota and California acquired in 2012, and higher restaurant operating profit at Company-operated restaurants. Operating EBITDA as a percentage of total revenues remains among the highest in the restaurant industry.
