SINGAPORE (Standard&Poor's) Nov. 20, 2006--Standard&Poor's Ratings Services today assigned its 'BB-' rating to State Bank of India's (SBI; BB+/Positive/B) proposed upper Tier II subordinated and hybrid Tier I notes under its US$2 billion MTN program. The differential between the 'BB+' counterparty credit rating and the 'BB-' rating on the upper Tier II and hybrid Tier I securities reflects the subordinated nature of the notes and embedded interest deferral feature. The interest deferral feature is linked to the compliance with the regulatory capital adequacy ratio (RCAR) and a profit test. This is, in turn, linked to the "balance in profit&loss account," which is a component of the reserves and surplus on a bank's balance sheet.
