Public Sector Undertaking (PSU) – Alternatively known as Public Sector Enterprise (PSE). It may be public limited company listed on stock exchanges with major ownership by a state government or a central government of India or it may be unlisted entity with major ownership by a state government or a central government of India.

Unlike in many other Western countries, Canadian businesses generally only have one form of incorporation available. Unlimited liability corporations can be formed in Alberta "AULC", British Columbia "BCULC" and Nova Scotia "NSULC". The aforementioned unlimited liability corporations are generally not used as operating business structures, but are instead used to create favorable tax positions for either Americans investing in Canada or vice versa. For U.S. tax purposes the ULC is classified as a disregarded entity.
