Flying Illini:
A 10Q is a quarterly financial report filed with the SEC (Security and Exchange Commission). It gives the stockholders of a company an update on the financial condition of a specific company. This report is not nearly as detailed as the annual filing which is known as a 10K.
For Delta guys it really means nothing. It appears on the surface that one of the reasons Delta delayed filing their report, was because of the sale of ASA. This sale has a major impact, in terms of dollars, on the financial statements and thus Delta waited to file. Now their could be countless other reasons why they filed late too.
