The accounting letter, or "going concern" qualification, would only be applicable in an audit, so they likely wouldn't have to deal with that until Feb-March of next year (based on December numbers and subject to any post-year end liquidity events that may have occured). The accountants would want to see the company has at least a year's worth of cash or vertually certain financing at the time of their opinion. The low cash balances would be a concern, and you're probably right about the$5 million barrier being crosed in October/November, but that in its own right is not a disclosable event, nor does it trigger an accounting opinion.
