On April 23, 2020, we revised to negative from stable our outlook on Bank of Scotland Plc, the bank account provider of Exchequer Partnership (No. 2) PLC (EP2), the operator of a U.K. government office building in London. The S&P underlying rating (SPUR) on EP2's senior debt is at the same level as our rating on the bank, and we see a weak link between the SPUR and the rating on the account bank. We are therefore revising our outlook on the SPUR on EP2's senior debt to negative from stable. We affirmed our 'AA' long-term issue rating on the debt, which benefits from an unconditional and irrevocable payment guarantee of scheduled interest and principal provided by Assured Guaranty (Europe)
