      <subfield code="a">We find that stock returns move in the direction of insurer rating changes in the 12-month period prior to the announcement. There is an additional stock price response following the announcement of a downgrade, but no response to upgrade announcements. The reaction to a downgrade is more pronounced when it involves a smaller insurer, when it spans multiple levels, or when it is a threshold downgrade. Returns are significantly more negative during the 12 months leading up to a downgrade announcement during the financial crisis (2008 and 2009) compared to other sample years</subfield>
