Questions about the coming wave of second mortgage writedowns

"In the lead-up to the credit crisis, I really didn’t write a considerable amount about second mortgages despite my focus on credit writedowns. At that time, I was more focused on writedowns from securitized mortgage paper (and later construction loans and commercial real estate because of the stress these loan types put on regional financials). However, second liens are a very big deal and I believe they will loom that much larger in 2010 because of the rise in strategic defaults in prime and Alt-A categories."
