Principal Financial Group, Inc.  Notes to Consolidated Financial Statements — (continued) 6.
Investments — (continued) investment that was called from us.
Gross realized losses related to other than temporary impairments of equity securities were $52.6 million and $3.0 million in 2007 and 2005.
We did not recognize any impairment losses on equity securities in 2006.
Gross Unrealized Losses for Fixed Maturities and Equity Securities For fixed maturities and equity securities available-for-sale with unrealized losses as of December 31, 2007 and 2006, the gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position are summarized as follows:
## Table 1 ##
As of December 31, 2007, we held $19,990.4 million in available-for-sale fixed maturity securities with unrealized losses of $1,187.6 million.
Of these amounts, Principal Life’s consolidated portfolio represented $19,574.5 million in available-for-sale fixed maturity securities with unrealized losses of $1,168.2 million.
Principal Life’s consolidated portfolio consists of fixed maturity securities where 95% are investment grade (rated AAA through BBB-) with an average price of 94 (carrying value/amortized cost).
Due to the credit disruption in the last half of 2007 that led to reduced liquidity and wider credit spreads, we saw an increase in unrealized losses in our securities portfolio.
The unrealized losses were more pronounced in structured products such as collateralized debt obligations and asset-backed securities.
For those securities that have been in a loss position for less than twelve months, Principal Life’s consolidated portfolio holds 1,268 securities with a carrying value of $11,897.8 million and unrealized losses of $785.5 million reflecting an average price of 94.
Of this portfolio, 93% was investment grade (rated AAA through BBB-) at December 31, 2007, with associated unrealized losses of $738.0 million.
The losses on these securities can primarily be attributed to changes in market interest rates and changes in credit spreads since the securities were acquired.
For those securities that have been in a continuous loss position greater than or equal to twelve months, Principal Life’s consolidated portfolio holds 945 securities with a carrying value of $7,676.7 million and unrealized losses of $382.7 million.
The average rating of this portfolio is A with an average price of 95 at December 31, 2007.
Of the $382.7 million in unrealized losses, the Corporate-public and Corporate-private sectors account for $283.8 million in unrealized losses with an average price of 95 and an average credit rating of BBB+.
The remaining unrealized losses consist primarily of $95.6 million in unrealized losses within the mortgage-backed and other asset-backed securities sector.
The average price of the mortgage-backed and other asset-backed securities sector is 96 and the average credit

Debt — (continued) Long-Term Debt The components of long-term debt as of December 31, 2007 and 2006, were as follows:
## Table 2 ##
The amounts included above are net of the discount and premium associated with issuing these notes, which are being amortized to expense over their respective terms using the interest method.
On October 16 and December 5, 2006, we issued $500.0 million and $100.0 million, respectively, of senior notes from our shelf registration, which became effective on June 30, 2004.
The notes bear interest at a rate of 6.05% per year.
Interest on the notes is payable semi-annually on April 15 and October 15 each year and began on April 15, 2007.
The notes will mature on October 15, 2036.
A portion of the proceeds was used to fund the acquisition of WM Advisors, Inc. , with the remaining proceeds being used for general corporate purposes.
On November 3, 2005, Principal International de Chile S. A. , a wholly owned indirect subsidiary, entered into long-term borrowing agreements with two Chilean banks in the amount of US $93.9 million.
This debt is denominated in Unidades de Formento (‘‘UF’’), a Chilean inflation-indexed, peso-denominated monetary unit.
Of this amount, US $49.0 million of UF +3.31% notes, which was refinanced from +4.59% during 2007, and US $44.9 million of UF +3.63% notes, which was refinanced from +4.93% in 2007, mature on November 3, 2011.
In November 2007, we paid down US $17.7 million on the UF +3.63% notes.
Interest on the notes is payable semi-annually on May 3 and November 3 each year.
The debt outstanding and interest expense will vary due to fluctuations in the Chilean peso to US dollar exchange rates and Chilean inflation.
On August 25, 1999, Principal Financial Group (Australia) Holdings Pty.
Limited, a wholly owned indirect subsidiary, issued $665.0 million of unsecured redeemable long-term debt.
Of this amount, $200.0 million of 7.95% notes matured on August 15, 2004, with the remaining $465.0 million in 8.2% notes due August 15, 2009.
In August 2007, we repurchased $10.0 million of the remaining notes, leaving $455.0 million in 8.2% notes due on August 15, 2009.
Interest on the notes is payable semiannually on February 15 and August 15 of each year.
Principal Financial Group (Australia) Holdings Pty.
Limited used the net proceeds from the notes to partially fund the purchase of the outstanding stock of several companies affiliated with Bankers Trust Australia Group.
On December 28, 2001, all of the long-term debt obligations of Principal Financial Group (Australia) Holdings Pty.
Limited were assumed by its parent, Principal Financial Services, Inc.  On March 10, 1994, Principal Life issued $100.0 million of surplus notes due March 1, 2044, at an 8% annual interest rate.
None of our affiliates hold any portion of the notes.
Each payment of interest and principal on the notes, however, may be made only with the prior approval of the Commissioner of Insurance of the State of Iowa (the ‘‘Commissioner’’) and only to the extent that Principal Life has sufficient surplus earnings to make such payments.
Interest of $8.0 million for each of the years ended December 31, 2007, 2006 and 2005 was approved by the Commissioner, and charged to expense.
Subject to Commissioner approval, the notes due March 1, 2044, may be redeemed at Principal Life’s election on or after March 1, 2014, in whole or in part at a redemption price of approximately 102.3% of par.
The approximate 2.3% premium is scheduled to gradually diminish over the following ten years.
These notes may be redeemed on or after March 1, 2024, at a redemption price of 100% of the principal amount plus interest accrued to the date of redemption.
The non-recourse mortgages, other mortgages and notes payable are primarily financings for real estate developments.
We, including certain subsidiaries, had $35.0 million in credit facilities as of December 31, 2007, with various financial institutions, in addition to obtaining loans with various lenders to finance these developments.
