Chapters X, XI and XII
before Chapter 11 of the Bankruptcy Reform Act of 1978, these three chapters of bankruptcy existed for company bankruptcies that involved reorganization. Chapter X involved reorganization for larger companies that held public debt or equity. Chapter XI was for readjustment of debts of smaller, non-publicly held companies, and Chapter XII was for companies with extensive holdings of real property (Glossary of Common Bankruptcy Terms)
