Graeme Lowdon insists Marussia will be on the grid this season despite being listed as 'subject to confirmation' on the official entry list.
On Friday, the FIA confirmed the teams and drivers for this season with Marussia appearing on the list with Jules Bianchi and Max Chilton as the two drivers.
The team, however, had a note by its name that stated 'subject to confirmation'.
But despite that, Lowdon is adamant there are no concerns about Marussia's participation.
"That will disappear in the next few days," the sporting director told Autosport.
"It's purely a timing and administrative thing. No concerns over it at all."
He added that the team will be present at the very first pre-season test in January where they will run their new Ferrari-powered MR.
"We plan to be at Jerez. There is nothing stopping it at the moment.
"All teams are going to want to do all of the test. Testing is something that's restricted and if it's restricted it generally means that you want to do it so we certainly plan, like most teams, to be there.
"Equally, there are thousands of components and any one can make you rethink or change plans. Your car might still be ready and you want to rethink how you go about something.
"And I am sure every other team is in the same situation. I don't think anyone has a completed car in the garage being dusted down at the moment and if they did it means they weren't using all of the available design time."
