VI. Credit Spread Database Compilation Instructions - The overall market credit spreads, commercial bank secondary perpetual spreads, and urban investment/industrial perpetual bond credit spreads are calculated based on ChinaBond medium- and short-term notes and ChinaBond perpetual bond data, with historical quantiles since the beginning of 2015; the credit spreads related to urban investment and industrial bonds are compiled and statistically analyzed by Cinda Securities R & D Center, with historical quantiles since the beginning of 2015 [36]. - 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 bond (calculated by linear interpolation method), and finally the credit spreads of the industry or regional urban investment are obtained by the arithmetic mean method [36]. - The excess spreads of bank secondary capital bonds/perpetual bonds are calculated as the credit spreads of bank secondary capital bonds/perpetual bonds minus the credit spreads of bank ordinary bonds of the same grade and term; the excess spreads of industrial/urban investment perpetual bonds are calculated as the credit spreads of industrial/urban investment perpetual bonds minus the credit spreads of medium-term notes of the same grade and term [37]. - Sample selection criteria: Industrial and urban investment bonds both select medium-term notes and public corporate bond samples, and exclude guaranteed bonds and perpetual bonds; if the remaining term of an individual bond is less than 0.5 years or more than 5 years, it will be excluded from the statistical sample; industrial and urban investment bonds are both externally subject-rated, while commercial banks use ChinaBond implicit bond ratings [38].
