A TV production firm has said that it expects more work from the BBC, despite making a misleading trailer about a photo shoot involving the Queen.
RDF Media made the documentary for BBC One
RDF Media has admitted it was to blame for a "serious error of judgement" in making the misleading promotional film.
But in a bid to calm investors' fears, said it was "confident" that the BBC would continue to commission work.
The problems with the trailer have raised issues of trust at the BBC and led to an inquiry into what went wrong.
RDF, the company behind shows such a Wife Swap, said that about 10% of its revenues came from the corporation.
The firm produced a clip from A Year With The Queen that showed the monarch "walking out in a huff".
RDF chief executive David Frank accepted it was edited out of sequence.
In a statement to the stock market, Mr Frank said: "The directors are confident that RDF will be able to satisfy the BBC that it will put in place steps to ensure an incident of this sort does not happen again.
"The directors are also confident therefore that the BBC will resume commissioning new programmes from RDF."
Any pause in commissioning would not have a material impact on its results, it added.
Earlier Mr Frank had sent an e-mail to BBC director general Mark Thompson apologising unreservedly for "the embarrassment this has led to for both the BBC and the Queen".
He added he hoped the BBC's trust in RDF could be rebuilt but that "I realise we've got a lot to make up".
Mr Thompson responded, saying he appreciated Mr Frank's "acknowledgement of RDF's role in this very regrettable episode and your unreserved apology."
The trailer was shown during the press launch for BBC One's autumn season last week.
In it, photographer Annie Leibovitz was seen telling the Queen she would look better without her tiara because "the Garter robe is so..."
Before she could say anything else, the Queen replied, pointing to what she was wearing: "Less dressy. What do you think this is?"
The clip then cut to the Queen walking through Buckingham Palace, saying to her lady-in-waiting "I'm not changing anything. I've had enough dressing like this, thank you very much", implying she had stormed off from the portrait session.
But in fact, that clip was filmed before the exchange over the tiara.
