The Bluebirds were not able to sign players during the summer due to a transfer embargo as they had outstanding debts to Her Majesty's Revenue & Customs (HRMC) and other football clubs.
Despite having unpaid debts to Motherwell that embargo was lifted, allowing the Bluebirds to sign Tom Heaton, Daniel Drinkwater, Jason Koumas, Seyi Olofinjana and Craig Bellamy on loan.
Those signings brought a furious response from Motherwell, who were owed £100,000 in January and £75,000 this summer. They started legal action, saying their should have been paid before Cardiff started spending money on players.
Jenkins, however, insisted those signings - in particular of Bellamy - have generated additional revenue which is now being used to settle their debts.
They paid half of what they owe Motherwell during the week, and say the remaining amount will be sent by Wednesday.
"I think it [the signing of Bellamy] helps raise our profile and there has certainly been lots of discussion about it but we think as a business and as a sporting case this deal stacks up," Jenkins told the BBC.
"We had a sell-out yesterday [against Doncaster on Saturday]. obviously the much-publicised jersey sales have increased.
"I don't think there is another chief executive in the Championship who if faced with the deal and the opportunity that I had who would have turned it down."
