# Subsidiary Company — Section 2(87)
A company C is a subsidiary of company H (the holding) if H satisfies either of the two control tests:
## The two control tests
| Test | What it means |
|---|---|
| (i) Board Composition Test | H controls the composition of the Board of Directors of C — i.e., H can, in its discretion, appoint or remove all or a majority of the directors of C. |
| (ii) Voting Power Test | H exercises or controls more than 1/2 of the total voting power in C — alone, or together with one or more of its subsidiaries. |
Either test is sufficient. Both are independently enough.
## Layering restriction
> Prescribed class(es) of holding companies shall not have layers of subsidiaries beyond such numbers as may be prescribed.
Under Rules, holding companies are generally restricted to not more than 2 layers of subsidiaries (subject to specified exceptions — wholly owned subsidiary outside India, banking, insurance, NBFCs, government companies).
## Key clarifications (Explanation)
- (a) Indirect control counts. If C controls D, and H controls C, then D is also a subsidiary of H — even though H doesn't directly hold D.
- (b) Board control is deemed where H 'by exercise of some power exercisable by it at its discretion can appoint or remove all or a majority of the directors'.
- (c) 'Company' includes body corporate. So subsidiary chains may include LLPs and foreign body corporates.
- (d) 'Layer' in relation to a holding company means its subsidiary or subsidiaries.
## Crucial carve-out — fiduciary capacity
> Shares held by a company, or power exercisable by it in another company, in a fiduciary capacity shall NOT be counted for the purpose of determining the holding-subsidiary relationship.
So if H is a custodian/trustee holding 60% in C on behalf of some other entity, those shares don't count for the >50% voting power test.
## Practical visual
```
H (Holding)
| (>50% voting power OR Board composition control)
v
C (Subsidiary)
| (>50% control)
v
D (deemed subsidiary of H also, by Explanation (a))
```
## Why this matters
- Triggers consolidation under Sec 129.
- Triggers restrictions under Sec 19 (subsidiary cannot hold shares in holding).
- Triggers RPT treatment under Sec 2(76).
- Triggers public-company deeming under Sec 2(71) proviso.
