David is the new CFO of Dunder Mifflin and as a result, all of the regional managers were to meet with him in the episode Valentine's Day. Although Michael appeared to embarrass himself in front of David, Jan, and the other regional managers with his "Faces of Scranton" video presentation, he was still able to produce the financial projections requested. Craig (the regional manager of the Albany branch) forgot to bring his branch's financial information altogether and therefore, looked like more incompetent than Michael. In his defense, Craig mentioned Michael's "relationship" with Jan to get himself out of hot water with David. In the end, Michael explained to David that his relationship with Jan was completely professional, and convinced David that Craig's story was based on a joke. Since Craig had already made a fool of himself, David took Michael and Jan at their word, and considered the matter resolved.
An interesting note: in great continuity it was mentioned in a previous episode, Sexual Harassment, that the former CFO, Randall, resigned due to sexual harassment charges, which explains why David came on as the new CFO.
