The credit rating parameters may be selected to return bonds of various credit quality. The 'or' selector will limit the results to bonds that meet either the Moodys or S&P selection. The 'and' selector limits the results to bonds that fall within both the Moody's and S&P selection for minimum or maximum.

For example, to return offerings from the query that are double-A rated in either Moodys or S&P, select 'Aa' from the Moodys minimum drop-down selection and 'AA' from the S&P drop-down selection. The 'and/or' radio button defaults to 'or'. When the query is executed offerings that are rated double-A in either category are returned.

To return offering that are rated double-A by both ratings agencies, change the 'or' selection to 'and'.
