(Garcia-Terul and Martinez-Solano, 2000: p. 164). Investments in working capital constitute a tradeoff between risk and profitability because decisions that increase profitability also increase risk and vice versa. This is obvious even in capital markets where a tradeoff exists between risk and profitability. For example, investments in equities tend to be riskier than investments in savings accounts and bonds but equities tend to pay higher returns that savings accounts and bonds. (Bodie et al, 2005). A company that has a negative net working capital therefore faces higher risks than a company that has a positive net working capital irrespective of the profitability of the company. This is so because, the company with higher current liabilities may have high levels of debts that may be uncollectible, but which must have been included in the sales figure used in calculating profit.

Thus, corporations must choose from the various financing options appropriate for them. These include, warrants issuance, derivatives instruments, common stocks and Preferred stocks etc. (Ambarish, John &Williams 1987).

What specifically qualifies as a security is dependent on the regulatory structure in a country. For example private investment pools may have some features of securities, but they may not be registered or regulated as such if they meet various restrictions (Ross, Westerfield & Jaffe 1999). Issuers include individuals, commercial banks, mortgage institutions and other international institution like the World bank.
2.1 Common stocks
