The rules comprising this compilation have been grouped according to subject matter under broad classifications, designated regulations, and subdivisions called articles. The sequence in which articles and sections have been arranged is based in general on the chronological order of steps involved in the registration of securities. Rules relating to the same subject matter have been assigned section numbers in the same 100 series so far as practicable. In accordance with this plan, and in order that any additional rule adopted in the future may be assigned a number at the point appropriate to the subject matter, no attempt has been made to number the sections consecutively.
