  • An Introduction to Corporate Guarantee

    In the UAE, the risk management activities inherent in running a corporate or investment banking business remain of crucial importance, not least because of the strong local characteristic of “name lending”, by which is meant lending or providing other banking facilities to family or other private businesses, primarily on the strength of the “name” or “names” of the proprietors standing behind the business, rather than on the strength of the asset quality and underlying credit of the particular business. Of course, in practice, there is commercial overlap between the proprietors and the companies which they own, but the credit analyses can break down where poor banking practices and procedures result in poorly constructed legal documentation and gaps in guarantee and security support documents.
