| Promising as it is for minority businesses, this
increased patronage poses dangers for them, too.
First, minority firms risk expanding too fast and
overextending themselves financially, since most
(30) are small concerns and, unlike large businesses,
they often need to make substantial investments in
new plants, staff, equipment, and the like in order
to perform work subcontracted to them. If, there-
after, their subcontracts are for some reason
(35) reduced, such firms can face potentially crippling
fixed expenses. The world of corporate purchasing
can be frustrating for small entrepreneurs who get
requests for elaborate formal estimates and bids.
Both consume valuable time and resources, and a
small company’s efforts must soon result in
orders, or both the morale and the financial health
of the business will suffer.

(D) increase its spending with minority subcontractors
