Item 7.01 Regulation FD Disclosure

The following information is provided in response to inquiries by investors about exposure to monoline insurance companies (i.e., bond insurers (“Monolines”)) and mortgage insurance companies (“Mortgage Insurers”). The following is an overview of Principal Life Insurance Company’s (“PLIC”) exposure to Monolines and Mortgage Insurers as of December 31, 2007. All values are based on GAAP carrying values, except where noted.

PLIC had $996.5 million of exposure to Monolines and Mortgage Insurers. Of the $996.5 million in total exposure, Monolines and Mortgage Insurers provided guarantees (“Wrapped Guarantees”) on $774.1 million of underlying municipal bonds, corporate credit, or asset backed securities (“ABS”). Of the $774.1 million, 44% was municipal bonds (99% of which was rated investment grade), 40% was investment grade bank perpetual preferreds, 9% was ABS backed by investment grade subprime first lien mortgages, and 7% was investment grade corporate bonds. PLIC owned securities issued by Monoline and Mortgage Insurers ("Direct Exposure") totaling $222.4 million. The following table provides detail of PLIC’s exposure in millions as of December 31, 2007:

Monoline or Mortgage Insurer	Direct Exposure	Wrapped Guarantees	Total
MBIA	$0.4	$375.1	$375.5
AMBAC	30.1	204.0	234.1
FGIC	50.5	143.2	193.7

RAM Holdings	5.3	0.0	5.3

Total	$222.4	$774.1	$996.5

During the month of February, 2008, PLIC's exposure to FGIC on an amortized basis (as opposed to GAAP carrying value) decreased. Based on amortized cost, our Direct Exposure and Wrapped Guarantee exposure as of February 29, 2008 was $17.3 million and $142.7 million, respectively, for a total exposure of $160 million, compared to our Direct Exposure and Wrapped Guarantee exposure to FGIC at December 31, 2007 of $55.6 million and $143.1 million, respectively, for a total exposure of $198.7 million.
