In general, the underwriters selected by platform companies should have certain strength and credibility, so as to better serve the platform companies and provide corresponding distribution and sales support. Generally speaking, platform companies will choose securities companies with higher ratings as underwriters, because securities companies with higher ratings tend to have more stable financial conditions, good reputation and can provide better services.
C-class securities companies usually refer to securities companies with lower ratings, and their financial status and reputation may be relatively weak. Therefore, when selecting underwriters, platform companies generally give priority to securities companies with higher ratings. But I must point out that the decision to choose an underwriter may be different according to the specific situation of the platform company. In practice, platform companies can make a choice according to their own needs and specific conditions, taking into account various factors, including underwriter rating, fees, service quality, etc.
In short, when issuing bonds, platform companies generally choose securities companies with higher ratings as underwriters to ensure good service and support. The probability of choosing a C-class securities company as an underwriter may be very small, because its financial situation and credibility are relatively weak.
