In the UK there was initially a widespread belief that a corporation needed to demonstrate its creditworthiness by having its shares only partly paid, as where shares are partly paid, the investor would be liable for the remainder of the nominal value in the event that the company could not pay its debts. Shares with nominal values of up to £1,000 were therefore subscribed to with only a small payment, leaving even a limited liability investor with a potentially crushing liability and restricting investment to the very wealthy. During the Overend Gurney crisis (1866–1867) and the Long Depression (1873–1896) many companies fell into insolvency and the unpaid portion of the shares fell due. Further, the extent to which small and medium investors were excluded from the market was admitted and, from the 1880s onwards, shares were more commonly fully paid.
