## Table 1 ##
The following table sets forth the composition of the portion of our fixed maturity securities portfolio by industry category attributable to the Closed Block Business as of the dates indicated and the associated gross unrealized gains and losses.
## Table 2 ##
(1) Investment data has been classified based on Lehman industry categorizations for domestic public holdings and similar classifications by industry for all other holdings.
As a percentage of amortized cost, fixed maturity investments attributable to the Closed Block Business as of December 31, 2006 consist primarily of 18% finance sector, 17% manufacturing sector, 17% asset-backed securities sector, 12% utilities sector, and 10% services sector compared to 18% manufacturing sector, 15% asset-backed securities sector, 14% finance sector, 12% utilities sector, and 10% U. S.  government sector as of December 31, 2005.
As of December 31, 2006, 86% of the mortgage backed securities in the Closed Block Business were publicly traded agency pass-through securities related to residential mortgage loans.
Collateralized mortgage obligations represented the remaining 14% of mortgage backed securities (and 1% of total fixed maturities in the Closed Block Business).
The gross unrealized losses related to our fixed maturity portfolio attributable to the Closed Block Business were $0.4 billion as of December 31, 2006 compared to $0.3 billion as of December 31, 2005.
The gross unrealized losses as of December 31, 2006 and December 31, 2005 were concentrated primarily in the manufacturing, utilities, and finance sectors.
Fixed Maturity Securities Credit Quality The Securities Valuation Office, or SVO, of the National Association of Insurance Commissioners, or NAIC, evaluates the investments of insurers for regulatory reporting purposes and assigns fixed maturity securities to one of six categories called “NAIC Designations.
” NAIC designations of “1” or “2” include fixed maturities considered investment grade, which include securities rated Baa3 or higher by Moody’s or BBB- or higher by Standard & Poor’s.
NAIC Designations of “3” through “6” are referred to as below investment grade, which include securities rated Ba1 or lower by Moody’s and BB+ or lower by Standard & Poor’s.
As a result of time lags between the funding of investments, the finalization of legal documents and the completion of the SVO filing process, the fixed maturity portfolio generally includes securities that have not yet been rated by the SVO as of each balance sheet date.
Pending receipt of SVO ratings, the categorization of these securities by NAIC designation is based on the expected ratings indicated by internal analysis.
Investments of our international insurance companies are not subject to NAIC guidelines.
Investments of our Japanese insurance operations are regulated locally by the Financial Services Agency, an agency of the Japanese government.
The Financial Services Agency has its own investment quality criteria and risk control standards.
Our Japanese insurance companies comply with the Financial Services Agency’s credit quality review and risk monitoring guidelines.
The credit quality ratings of the non-U.
S.  dollar denominated investments of our Japanese insurance companies are based on ratings assigned by Moody’s, Standard & Poor’s, or rating equivalents based on ratings assigned by Japanese credit ratings agencies.
The amortized cost of our public and private below investment grade fixed maturities attributable to the Financial Services Businesses totaled $7.1 billion, or 6%, of the total fixed maturities as of December 31, 2006 and $6.0 billion, or 6%, of the total fixed maturities as of December 31, 2005.
Below investment grade fixed maturities represented 11% of the gross unrealized losses attributable to the Financial Services Businesses as of December 31, 2006, compared to 14% of gross unrealized losses as of December 31, 2005.
The amortized cost of our public and private below investment grade fixed maturities attributable to the Closed Block Business totaled $6.2 billion, or 13%, of the total fixed maturities as of December 31, 2006 and $5.9 billion, or 13%, of the total fixed maturities as of December 31, 2005.
Below investment grade fixed maturities represented 16% of the gross unrealized losses attributable to the Closed Block Business as of December 31, 2006, compared to 24% of gross unrealized losses as of December 31, 2005.
We have four tranches of senior notes outstanding: $250 million aggregate principal amount of 1.4 percent notes due November 30, 2014, $500 million aggregate principal amount of 4.625 percent notes due November 30, 2019, $300 million aggregate principal amount of 3.375 percent notes due November 30, 2021 and $500 million aggregate principal amount of 5.75 percent notes due November 30, 2039.
Interest on each series is payable on May 30 and November 30 of each year until maturity.
The estimated fair value of our Senior Notes as of December 31, 2013, based on quoted prices for the specific securities from transactions in over-the-counter markets (Level 2), was $1,649.5 million.
We may redeem the Senior Notes at our election in whole or in part at any time prior to maturity at a redemption price equal to the greater of 1) 100 percent of the principal amount of the notes being redeemed; or 2) the sum of the present values of the remaining scheduled payments of principal and interest (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the date of redemption on a semi-annual basis at the Treasury Rate (as defined in the debt agreement), plus 15 basis points in the case of the 2014 Notes, 20 basis points in the case of the 2019 Notes and 2021 Notes, and 25 basis points in the case of the 2039 Notes.
We would also pay the accrued and unpaid interest on the Senior Notes to the redemption date.
We have entered into interest rate swap agreements which we designated as fair value hedges of underlying fixedrate obligations on our Senior Notes due 2019 and 2021.
See Note 13 for additional information regarding the interest rate swap agreements.
Before our senior notes due November 30, 2014 become payable, we intend to issue new senior notes in order to pay the $250 million owed.
If we are not able to issue new senior notes, we intend to borrow against our Senior Credit Facility to pay these notes.
Since we have the ability and intent to refinance these senior notes on a long-term basis with new notes or through our Senior Credit Facility, we have classified these senior notes as long-term debt as of December 31, 2013.
We also have available uncommitted credit facilities totaling $50.7 million.
At December 31, 2013, the weighted average interest rate for our long-term borrowings was 3.3 percent.
At December 31, 2012, the weighted average interest rate for short-term and long-term borrowings was 1.1 percent and 3.5 percent, respectively.
We paid $68.1 million, $67.8 million and $55.0 million in interest during 2013, 2012 and 2011, respectively.12.
ACCUMULATED OTHER COMPREHENSIVE INCOME OCI refers to certain gains and losses that under GAAP are included in comprehensive income but are excluded from net earnings as these amounts are initially recorded as an adjustment to stockholders’ equity.
Amounts in OCI may be reclassified to net earnings upon the occurrence of certain events.
Our OCI is comprised of foreign currency translation adjustments, unrealized gains and losses on cash flow hedges, unrealized gains and losses on available-for-sale securities, and amortization of prior service costs and unrecognized gains and losses in actuarial assumptions on our defined benefit plans.
Foreign currency translation adjustments are reclassified to net earnings upon sale or upon a complete or substantially complete liquidation of an investment in a foreign entity.
Unrealized gains and losses on cash flow hedges are reclassified to net earnings when the hedged item affects net earnings.
Unrealized gains and losses on available-for-sale securities are reclassified to net earnings if we sell the security before maturity or if the unrealized loss is considered to be other-than-temporary.
We typically hold our available-for-sale securities until maturity and are able to realize their amortized cost and therefore we do not have reclassification adjustments to net earnings on these securities.
Amounts related to defined benefit plans that are in OCI are reclassified over the service periods of employees in the plan.
The reclassification amounts are allocated to all employees in the plans and therefore the reclassified amounts may become part of inventory to the extent they are considered direct labor costs.
See Note 14 for more information on our defined benefit plans.
