1. Private vs. public (the great divide): the private company — closed membership (the Act's numerical cap), restricted share transfer, no public invitation; the public company — the minimum-membership floor (seven), the public-invitation power, the fuller compliance regime.
2. Companies limited by shares (the dominant form) vs. by guarantee (the not-for-profit's form).
3. Government companies (state ownership's corporate face) and foreign companies (incorporated abroad, operating through branches/liaison — FITTA 2075's gate).
4. Holding and subsidiary companies (control's chain); listed and unlisted (NEPSE's discipline).
5. Profit-distributing vs. "company not distributing profits" — Nepal's statutory non-profit company.
6. Small vs. large (the Act's classification driving audit and compliance tiers).
