The historical quantiles are since the beginning of 2015. The credit spreads related to urban investment and industrial bonds are compiled and statistically analyzed by the R & D Center of Cinda Securities, and the historical quantiles are also since the beginning of 2015 [37]. - The credit spreads of industrial and urban investment individual bonds are calculated as the individual bond's ChinaBond valuation (exercise) minus the yield to maturity of the same - term China Development Bank bonds (calculated by the linear interpolation method), and finally the credit spreads of the industry or regional urban investment are obtained by the arithmetic average method [37]. - The excess spreads of bank secondary - tier capital bonds/perpetual bonds are calculated as the credit spreads of bank secondary - tier capital bonds/perpetual bonds minus the credit spreads of the same - grade and same - term bank ordinary bonds. The excess spreads of industrial/urban investment - type perpetual bonds are calculated as the credit spreads of industrial/urban investment - type perpetual bonds minus the credit spreads of the same - grade and same - term medium - term notes [37]. - Industrial and urban investment bonds both select medium - term notes and public - offering corporate bonds as samples, and guarantee bonds and perpetual bonds are excluded. If the remaining maturity of an individual bond is less than 0.5 years or more than 5 years, it is excluded from the statistical sample. Industrial and urban investment bonds are based on external entity ratings, while commercial banks use ChinaBond implied debt - item ratings [37].
