Hello all,
Here is a little Govt. sponsored write-up on PVPs. While brief, it covers 
some 
history. I do not agree with much the author asserts/opines, and some of the 
information is out-of-date, such as fees and length of protection. These have 
been 
amended in the last couple of years. Just a starting point:

 Hope this helps,
