Underwriting

Rights issues may be underwritten. The role of the underwriter is to guarantee that the funds sought by the company will be raised. The agreement between the underwriter and the company is set out in a formal underwriting agreement. Typical terms of an underwriting require the underwriter to subscribe for any shares offered but not taken up by shareholders. The underwriting agreement will normally enable the underwriter to terminate its obligations in defined circumstances. A sub-underwriter in turn sub-underwrites some or all of the obligations of the main underwriter; the underwriter passes its risk to the sub-underwriter by requiring the sub-underwriter to subscribe for or purchase a portion of the shares for which the underwriter is obliged to subscribe in the event of a shortfall. Underwriters and sub-underwriters may be financial institutions, stock-brokers, major shareholders of the company or other related or unrelated parties.
