A Best Efforts underwriting agreement is primarily used for the sale of high-risk securities. An underwriting monitoring contract is used in combination with an offer of subscription rights. All monitoring sub-obligations are made on a fixed commitment basis. The underwriter on standby undertakes to buy all the shares that the current shareholders do not buy. The stand-by underwriter will then resell the titles to the public. As part of a Firm Commitment Underwriting, the underwriter guarantees the acquisition of all securities offered for sale by the issuer, that it can sell them to investors. This is the most desirable deal because it guarantees all the issuer`s money immediately. The more the offer is requested, the more likely it is to be made on a fixed commitment basis. .
