"In the Handelszeitung there were things reported that are not true," boss Kaltenborn told Speed Week at Monza.
"We have already said that we are in a challenging situation.
"Through this (Russian) partnership, there is an upward trend, but it takes time," she explained.
"It has been a noticeable step for us and our suppliers, and we remain in contact with them -- but it is an internal matter.
"It is obvious that we will meet all of our liabilities, and we thank our suppliers for their patience.
"Our goal is to lead the company out of this situation, for the benefit of our employees and our suppliers, as was the case for the last 43 years," added Kaltenborn.
