"I'll work very hard to bring a fresh perspective and build some trust," said Miles of the task ahead of him. "You can't just ignore history, and I won't here. But the sport I hope to find will recognise that [the success of the series] is predicated on our ability to work together.
Among the issues on his to-do list are wrapping up Lotus' faltering involvement with the series as an engine supplier; sorting out problems with tyre providers Firestone; resolving a dispute with team owners about the cost of parts for the new Dallara chassis and a decision about whether or not to introduce bespoke aero kits to the car in 2013; and the specification of new chassis and engines for the junior Indy Lights series.
"Jeff understands racing and has relationships throughout the industry that have developed during his tenure with the company," said Miles. "Allowing him to focus on IMS and IndyCar will greatly benefit Hulman & Co."
In terms of the 2013 season, Belskus has already confirmed that next year's racing calendar previously announced by Bernard - which include three double-header events and a return to Pocono Raceway and to Reliant Park in Houston - would proceed as planned.
Miles acknowledged that the company itself could be doing a much better job of conveying its intentions to business partners, the media and to fans. "It's not always clear internally or externally what our priorities are and where we're headed," he admitted. "I think we can make that clearer."
Added Mari Hulman George: "The racing components of our business are very important to our company, and Jeff is uniquely positioned to help lead us into 2013 and beyond as he has complete understanding of our sport and our 2013 plan and an excellent relationship with our key stakeholders.
"By allowing Jeff to focus on the racing businesses and significantly less on the other business units, we are clearly aligning our executive management team to move the company forward," she added.
Belskus added that the appointment of Miles in his former role as Hulman & Co. CEO - which is effective from December 17 - was one that he was very much in favour of.
"Mark and I have known each other for many years and have worked together closely since he joined the Hulman & Co. board," he said. "Mark brings a wealth of experience and has a good understanding of the opportunities and challenges that face our business. I believe he will be very helpful in bringing new and successful ideas to the company."
