and in China, increasing our exclusive brands penetration as well as closing unprofitable stores and enhancing holiday profitability.  ?
Efficient and Effective Enterprise.
We became a more efficient and effective enterprise in fiscal 2010 by re-engineering our cost structure to deliver cost reductions or leverage across several revenue categories.
We believe we can sustain our more efficient cost structure to conserve our resources now and progress as the economic environment recovers.
In fiscal 2010, we improved our selling, general and administrative expenses (“SG&A”) rate by 0.1% of revenue to 19.9% of revenue and our Domestic segment’s SG&A rate by 0.6% of revenue to 18.6% of revenue, each as compared to the prior-year period.
For further discussion, see the Segment Performance Summary below.
Results of Operations Fiscal 2010 Summary ?
Net earnings increased 31.3% to $1.3 billion, or $3.10 per diluted share, compared with $1.0 billion, or $2.39 per diluted share, in fiscal 2009.
The increase in net earnings was the result of increases in both the Domestic and International segments’ operating income, driven primarily by revenue growth and a modest increase in the gross profit rate, as well as a modest reduction in our SG&A rate.
In addition, there was a decrease in restructuring and no impairment charges compared to the prior year.  ?
Revenue increased 10.4% to $49.7 billion.
The increase was driven primarily by the acquisition impact of Best Buy Europe, which was acquired in the second quarter of fiscal 2009 and contributed its first full year of revenue in fiscal 2010; the net addition of 85 new stores during fiscal 2010; a comparable store sales gain of 0.6% and the favorable effect of fluctuations in foreign currency exchange rates.  ?
Our gross profit rate increased by 0.1% of revenue to 24.5% of revenue.
The increase was driven primarily by the acquisition impact of Best Buy Europe, which has a normally higher gross profit rate than our other businesses.
The increase was partially offset by a decrease in our Domestic segment’s gross profit rate due principally to changes in revenue mix compared to the prior year.  ?
Our SG&A rate decreased by 0.1% of revenue to 19.9% of revenue.
The decrease was due primarily to reductions in various discretionary categories and the leveraging impact of higher comparable store sales on payroll and benefits in our Domestic segment.
Partially offsetting these decreases were the acquisition impact of Best Buy Europe, which has a normally higher SG&A rate than our other businesses, and higher incentive pay expense in our Domestic segment due to improvements in operating performance compared to the prior year.  ?
In the first quarter of fiscal 2010, we recorded $52 million in restructuring charges related primarily to updating our U. S.  Best Buy store operating model, which included eliminating certain positions, as well as employee termination benefits and business reorganization costs in Best Buy Europe.  ?
We ended fiscal 2010 with $1.8 billion of cash and cash equivalents, compared with $498 million at the end of fiscal 2009.
Operating cash flow increased 17.5% to $2.2 billion in fiscal 2010 compared to fiscal 2009 operating cash flow of $1.9 billion, while capital expenditures decreased 52.8% to $615 million.  ?
During fiscal 2010, we made four dividend payments totaling $0.56 per share, or $234 million in the aggregate.

post-retirement benefit plans.
The health care plan is contributory, with participants’ contributions adjusted annually, and the life insurance plan is non-contributory.
We fund domestic pension liabilities in accordance with the limits imposed by ERISA, federal income tax laws and the funding requirements of the Pension Protection Act of 2006.
We fund non-domestic pension liabilities in accordance with laws and regulations applicable to those plans.
We broadly diversify our pension plan assets, consisting primarily of domestic and international common stocks and fixed income securities.
Short-term and long-term liabilities associated with benefit plans are primarily determined based on actuarial calculations.
These calculations consider payroll and employee data, including age and years of service, along with actuarial assumptions at the date of the financial statements.
We take into consideration long-term projections with regard to economic conditions, including interest rates, return on assets and the rate of increase in compensation levels.
With regard to liabilities associated with post-retirement benefit plans that provide health care and life insurance, we take into consideration the long-term annual rate of increase in the per capita cost of the covered benefits.
We review the discount rate assumptions and revise them annually.
The expected long-term rate of return on assets assumption (“asset return assumption”) for funded plans is of a longer duration and revised only when long-term asset return projections demonstrate that need.
Pension Plans Our pension plan costs and related assumptions were as follows:
## Table 1 ##
Net Periodic Pension Benefit Costs We believe that the service cost and amortization of prior service cost components of net periodic pension benefit cost reflect the ongoing operating cost of our pension plans, particularly since our most significant plans were closed to most new entrants after 2007.
The decrease in net periodic pension benefit cost from 2012 to 2013 was primarily due to the lower interest cost in the current year.
Our service cost and prior service cost amortization is expected to be approximately $4.8 million lower in 2014.
Interest cost, expected return on plan assets and amortization of net loss is expected to decrease in 2014 by $13.8 million due primarily to the 2013 actual return on plan assets, which exceeded the expected long-term return on plan assets assumption, and the higher discount rate.
For more information, see Note 14, Pension and Other Post-Retirement Benefit Plans.
Actuarial gains and losses may arise when actual experience differs from assumed experience or when we revise the actuarial assumptions used to value the plans’ obligations.
We only amortize the unrecognized net actuarial gains and losses in excess of 10% of a respective plan’s projected benefit obligation, or the fair market value of assets, if greater.
The estimated recognized net actuarial loss component of net periodic pension benefit expense for 2014 is $23.0 million.
The 2013 recognized net actuarial loss component of net periodic pension benefit expense was $40.4 million.
Projections beyond 2013 are dependent on a variety of factors such as changes to the discount rate and the actual return on pension plan assets.
The tables below present the balances of assets and liabilities measured at fair value on a recurring basis, as of December 31, 2010 and 2009, split between the Financial Services Businesses and Closed Block Business, by fair value hierarchy level.

with policyholders in bankruptcy where negotiations often involve a large number of claimants and other parties and require court approval to be effective.
As part of its continuing analysis of asbestos reserves, which includes an annual ground-up review of asbestos policyholders, the Company continues to study the implications of these and other developments.
The Company completed the annual ground-up review during the fourth quarter of 2005.
Also see “Part I—Item 3, Legal Proceedings.
” Because of the uncertainties set forth above, additional liabilities may arise for amounts in excess of the current asbestos and environmental reserves.
In addition, the Company’s estimate of claims and claim adjustment expenses may change.
These additional liabilities or increases in estimates, or a range of either, cannot now be reasonably estimated and could result in income statement charges that could be material to the Company’s operating results and financial condition in future periods.
INVESTMENT PORTFOLIO The Company’s invested assets at December 31, 2005 totaled $68.29 billion, of which 93% was invested in fixed maturity and short-term investments, 1% in equity securities, 1% in mortgage loans and real estate and 5% in other investments.
Excluding the impact on invested assets of securities lending, unrealized investment gains and losses, receivables for investment sales and payables on investment purchases, the pretax average yield was 4.7%, 4.8% and 5.3% and the after tax average yield was 3.7%, 3.7% and 4.0% for the years ended December 31, 2005, 2004 and 2003, respectively.
Because the primary purpose of the investment portfolio is to fund future claims payments, the Company employs a conservative investment philosophy.
The Company’s fixed maturity portfolio at December 31, 2005 totaled $58.98 billion, comprising $58.71 billion of publicly traded fixed maturities and $274 million of private fixed maturities.
The weighted average quality ratings of the Company’s publicly traded fixed maturity portfolio and private fixed maturity portfolio at December 31, 2005 were AA1 and A3, respectively.
Included in the fixed maturity portfolio at that date was approximately $1.75 billion of below investment grade securities.
During 2005, holdings of tax-exempt securities were increased to $31.46 billion to take advantage of their relatively high credit quality and attractive after-tax yields.
The average effective duration of the fixed maturity portfolio, including short-term investments, was 3.9 years as of December 31, 2005 (4.3 years excluding short-term investments), compared with 4.1 years as of December 31, 2004 (4.4 years excluding short-term investments).
The following table sets forth the Company’s combined fixed maturity investment portfolio classified by Moody’s Investors Service ratings:
