An Investment Holding Company is a company which generates its income through ownership of real estate or shares of other companies. The income could be through the sale and purchase of these assets, the rental income or the dividends received. The Accounting and Corporate Regulatory Authority (ACRA) defines this type of income as non-trade income. ACRA recognises Investment Holding Companies and such companies are accorded an SSIC Code. SSIC or Singapore Standard Industrial Classification is the national standard for classifying economic activities undertaken by economic units.
