What it means
The certificate is evidence of ownership rather than the ownership itself. What really counts is the entry in the company's records, which is why a lost certificate can usually be replaced by following the company's procedure.
The certificate simply shows what the records say. Historically, certificates were printed on decorative paper, signed by company officers and often carried a serial number and a corporate seal.
They were handed over when shares were sold, and a new certificate was issued to the buyer. This was slow and risky, because paper could be lost, stolen or forged.
Modern markets mostly use book-entry (electronic) holding, where a custodian or central depository records ownership in a database and no paper is issued. Investors usually see their holdings on a brokerage statement instead.
Private companies, however, still often issue certificates or electronic equivalents to founders, employees and early investors. Certificates matter in practice during fundraising, mergers and legal disputes.
Buyers and lenders ask to see the share register and the certificates because they need to be sure that the person selling the shares really owns them. Some certificates carry a legend, which is a printed note restricting resale or transfer.
For a non-finance manager the key point is to know where the records are kept. Keep the register of shareholders, issued certificates and any transfer paperwork in one controlled place, and make sure they agree with each other.
Mismatches between the register and the certificates are a common cause of delay in due diligence (the checking process before a deal). There is also a practical difference between certificated and uncertificated shares.
Certificated shares are held on paper and need the physical document to be sold, while uncertificated shares move by electronic instruction alone. Which form applies depends on the company, the type of share and the rules of the country where it is registered.
In practice
Real-world examples.
Example
A founder of a private logistics company receives a certificate for 400,000 shares, each with a nominal value of $0.01. When an investor later buys 100,000 of those shares, the founder surrenders the old certificate, and the company issues one for 300,000 to the founder and one for 100,000 to the investor.
Example
A shareholder in an old industrial company finds a paper certificate in a family attic and wants to sell. The company's transfer agent checks the number against its register, confirms the shares are still valid, and converts them to electronic form so the holder can sell through a broker.
Example
A start-up in a software sector is preparing for a funding round. The investor's lawyers ask for every certificate, plus the register, and discover that one early employee was promised shares but never received a certificate. The company has to correct the record before the round can close.
Case study
Seen in the real world.
Kestrel Marine Supplies is an illustrative, fictional private company owned by three founders and a small group of angel investors. When a larger investor offers $5,000,000 for a minority stake, its lawyers ask for the share register and every certificate in issue.
The finance manager discovers that two certificates carry the same serial number, and one early transfer was never recorded. Both problems arose because the original paperwork was kept in a drawer and updated by hand.
The company spends several weeks and a modest legal bill correcting the register, and the illustrative deal closes late. The finance manager then moves the register to an electronic system with a named owner, so the next investor finds a clean record on day one.
Watch out
Common mistakes.
- Assuming that losing the certificate means losing the shares, when ownership is recorded in the company's register and a replacement can normally be issued.
- Keeping the certificates and the share register in different places and letting them drift apart, which creates delays and disputes in a deal.
- Believing that all shares come with a paper certificate, when most listed shares are held electronically with no paper at all.
Questions
People also ask.
Do I need a stock certificate to own shares?
Not always, because ownership is established by the register or by the electronic holding record, and many companies issue no paper at all.
What happens if I lose a stock certificate?
You normally notify the company or its transfer agent, sign an affidavit of loss and sometimes pay a small indemnity fee, after which a replacement or an electronic holding is issued.
What is a restrictive legend?
It is a printed statement on the certificate saying the shares cannot be sold or transferred freely until certain conditions are met, such as a lock-up period or an exemption from registration.
