Guilder Share (New York Share)

An ownership stake in a Dutch company that can be traded in the United States because it represents shares that have been canceled in Dutch markets. Guilder Shares, also called New York Shares, represent a special international trading arrangement for shares of Dutch companies only, since the stocks of Dutch companies can't be traded through American depository receipts (ADR).

When buying shares of a company located in a foreign country, U.S. citizens will generally buy an ADR, a certificate that represents those foreign shares. Since the Netherlands do not allow Dutch company stock to be traded in other countries, a certain number of shares must be canceled in the Netherlands then grouped and sold as Guilder Shares that can then be issued in the U.S.
The guilder was also once the name of a Dutch currency.
