Also known as the interim period. This is the portion of the current fiscal year that has occurred or is reportable so far. For example, if a company is filing a Form 10-Q for its second fiscal quarter ended June 30, the stub period would be six months or the first half of the company's fiscal year.

Stub period financial statements, commonly referred to as interim financial statements, are typically unaudited, but are often subject to a review by the company's auditors in accordance with applicable auditing standards.
