Looking for bad news in SEC filings? Here are some tips. (thanks to Newman Library at Baruch College for these instructions)


    * Note if the company has filed an amended statement, a 10-K/A or a 10-Q/A.

    * Read the footnotes carefully.

    * Read Item 3 - Legal Proceedings and Item 13 - Related Party Transactions in the 10-K.

    * Check if the auditor has filed a "qualified opinion" or a "going concern" opinion.

    * Investigate the background of items reported in 8-K reports.

    * Do a text search of all the company's filings using words like legal, litigate, regulate, default, etc.


Identify Threats with the 10-K (thanks to Newman Library at Baruch College for these instructions)

    • Item 1 - Business

    • Item 7 - MD&A - Management Discussion and Analysis of Financial Condition
