Total insurance in force declined to $ 57.5 billion at June 30 , 2009 , a 4.9 % drop from March 31 , 2009 and a 13.3 % decline from June 30 , 2008 . Our persistency rates have remained high over the past year reflecting restrictive credit standards in mortgage lending and declining home prices , both of which limit the opportunities for borrowers to refinance existing mortgages . When credit becomes more available and home prices stabilize , however , we expect that our persistency rates and the related premium revenue will be negatively affected .
