Loss mitigation - Extension Agreement

We do not do modifications or formal forebearance agreements in collections. We do however, allow an extension up to 6 months and the borrower signs an agreement, usually for 2 months allowed of no payments. There is no extension of the maturity date and the terms of the agreement explain that interest does continue to accrue. This creates a small balloon payment at maturity date. Is this a problem under any of the new servicing rules? I mean the balloon?
