What it means
In the past, some companies issued shares that were assessable, which meant the company could call on shareholders for additional payments, called assessments, if it ran short of money or had debts to meet. This created a risk that an investor could lose more than the original purchase price.
Non-assessable stock removes that risk. With non-assessable shares, once the purchase price is paid in full, the shareholder has no further obligation.
If the company fails, the shareholder loses the value of the investment but nobody can demand extra funds from them to pay creditors. This is the basis of limited liability, which is a legal protection that limits owners' losses to what they put in.
Today the concept is mostly a matter of legal and historical interest, because ordinary shares in public and private companies are usually described as fully paid and non-assessable. You may see the wording in share certificates, offering documents and legal opinions about a share issue.
It tells the reader that there are no hidden calls on the shareholder's wallet. There are a few situations in which the point still matters.
Partly paid shares can have a balance still owing, and certain mutual or cooperative structures and some insurance or banking arrangements have historically allowed calls on members. When reading unfamiliar documents, check whether the shares are fully paid and whether any further liability exists.
For managers and founders, the practical point is easy to remember. If you buy fully paid, non-assessable shares, your downside is limited to the amount you invested.
Founders sometimes meet the phrase when they agree a funding round, because the investor's lawyers will ask the company to confirm that every new share is fully paid and non-assessable. It is a standard comfort statement, so it is normally easy to give, but it should still be checked against the company's records before anyone signs.
In practice
Real-world examples.
Example
A founder issues new shares to an angel investor, and the share issue documents state the shares are fully paid and non-assessable. The investor transfers $100,000 and has no further obligation to the company. If the business later closes, her loss is limited to that amount.
Example
A lawyer preparing an opinion letter for a financing round confirms that the new preferred shares are validly issued, fully paid and non-assessable. The lender relies on the letter. This gives the lender comfort that the equity is genuine and not subject to further calls.
Example
A retired teacher buys shares through a brokerage account in a listed retailer. She does not need to read any special terms because the shares are non-assessable, as with almost all listed stock. She knows that her worst case is losing what she paid.
Formula
Calculation
Maximum loss on non-assessable stock = number of shares x price paid per share
Suppose an investor buys 2,000 non-assessable shares at $15 each. The maximum loss = 2,000 x 15 = $30,000. If the company later fails with large debts, creditors cannot demand more than the $30,000 already paid. With assessable stock, the company could in theory demand a further payment, for example $5 per share, which would add 2,000 x 5 = $10,000 to the investor's potential loss.Case study
Seen in the real world.
Fenwick Mutual Supplies is a fictional trading cooperative created for this illustration. In its early days it issued assessable shares to its members, which meant the cooperative could ask them for extra funds if it ran into losses.
After a poor harvest season produced a shortfall of $240,000, the board debated whether to call on its 120 members, which would have meant $2,000 from each. Several members said they had joined to share purchasing power, not to take on open-ended liability.
The illustrative outcome was that the cooperative converted its capital into fully paid, non-assessable shares at the next general meeting. Membership applications increased because new joiners knew their maximum exposure.
Watch out
Common mistakes.
- Assuming non-assessable means the shares cannot lose value, when it only means no further payment can be demanded.
- Confusing non-assessable with fully paid, when partly paid shares might still be non-assessable while an agreed balance remains due.
- Believing all historic stock was non-assessable, when some early banking and insurance shares carried extra liability.
Questions
People also ask.
Does non-assessable mean the shares are risk free?
No, the share price can still fall to zero, but the holder cannot be forced to pay beyond the original amount.
Where will I see this wording?
You will usually find it in share certificates, prospectuses and legal opinions that describe shares as validly issued, fully paid and non-assessable.
Is it relevant to a private company?
Yes, because lenders and investors often ask for confirmation that shares are fully paid and non-assessable before they provide funds.
