Tampa restaurant group Outback Steakhouse is to invest in more advertising time on national TV over the coming months in a bid to turn around its average unit volumes, which fell 1.5% in its second quarter.

CEO Chris Sullivan explained: "We are being outspent significantly by other casual-dining concepts."

CFO Robert S. Merritt added: "We think [advertising spend] will keep us competitive." Most of the additional media spending will occur in the chain's fourth quarter.
