During the underwriting process, a Surety Company or an Agent may find that the small business presents a degree of risk beyond that which the Company or Agent is willing to assume without the SBA Guarantee.  For example, a small business may have limited working capital or lack evidence of prior, successful contract performance that causes concern.  Under the Surety Bond Guarantee Program, SBA guarantees between 70 and 90% of the losses and expenses incurred by the Surety Company should the small business default and fail to complete the contract.  This Government guarantee encourages the Surety Company to issue a bond that it would otherwise not issue to a small business
