Protection The following table presents the results of operations of our Protection segment on an operating basis:
## Table 0 ##
Our Protection segment pretax operating income, which excludes net realized gains or losses and the market impact on indexed universal life benefits (net of hedges and the related DAC amortization, unearned revenue amortization and the reinsurance accrual), decreased $37 million, or 10%, to $336 million for the year ended December 31, 2013 compared to $373 million for the prior year reflecting lower auto and home earnings.
Net Revenues Net revenues, which exclude net realized gains or losses and the unearned revenue amortization and the reinsurance accrual offset to the market impact on indexed universal life benefits, increased $99 million, or 5%, to $2.2 billion for the year ended December 31, 2013 compared to $2.1 billion for the prior year primarily due to the impact of unlocking and growth in auto and home premiums, as well as an increase in net investment income.
Net investment income, which excludes net realized gains or losses, increased $10 million, or 2%, to $439 million for the year ended December 31, 2013 compared to $429 million for the prior year due to an increase in investment income on fixed maturities driven by higher average invested assets for life and health.
Premiums increased $67 million, or 6%, to $1.2 billion for the year ended December 31, 2013 compared to $1.1 billion for the prior year primarily due to growth in auto and home premiums driven by new policy sales growth across market segments, primarily from our affinity relationships with Costco and Progressive.
Auto and home policy counts increased 11% year-over-year.
Other revenues increased $18 million, or 5%, to $410 million for the year ended December 31, 2013 compared to $392 million for the prior year primarily due to an $18 million unfavorable impact from unlocking for the year ended December 31, 2013 compared to a $41 million unfavorable impact in the prior year.
The primary driver of the unlocking impact to other revenues in both periods was lower projected gains on reinsurance contracts resulting from favorable mortality experience.
Expenses Total expenses, which exclude the market impact on indexed universal life benefits (net of hedges and the related DAC amortization), increased $136 million, or 8%, to $1.9 billion for the year ended December 31, 2013 compared to $1.7 billion for the prior year primarily due to an increase in benefits, claims, losses and settlement expenses.
Distribution expenses increased $9 million, or 17%, to $62 million for the year ended December 31, 2013 compared to $53 million for the prior year driven by higher compensation related to higher sales.
Benefits, claims, losses and settlement expenses, which exclude the market impact on indexed universal life benefits (net of hedges), increased $106 million, or 9%, to $1.3 billion for the year ended December 31, 2013 compared to $1.1 billion for the prior year due to the impact of unlocking, higher expenses related to our auto and home business, an
We expect net interest expense of approximately $135 to $140 in 2011, subject to capital deployment activities during the year.
Our effective tax rate was 31.2 percent in 2008, 31.5 percent in 2009 and 30.7 percent in 2010.
The 2008 rate includeda$35, or approximately $0.09 per-share, benefit from the settlement of tax refund litigation, which reduced the 2008 tax rate by 100 basis points.
We anticipate an effective tax rate of approximately 31 percent in 2011.
For additional discussion of tax matters, see Note E to the Consolidated Financial Statements.
In 2008, we entered into an agreement to sell our Spanish nitrocellulose operation and recognized a pretax loss of $11 in discontinued operations in anticipation of the sale.
The sale of this operation was completed in 2010.
Our reported revenues exclude the revenues associated with this divested business.
We have presented the operating results of this business, along with the loss from the sale, as discontinued operations, net of income taxes.
R E V I EW OF BU S I NESS GROU P S AEROSPACE Review of 2010 vs.  2009
## Table 1 ##
The Aerospace group’s revenues increased in 2010 compared with 2009 due primarily to steady growth in aircraft services activity throughout the year.
Aircraft manufacturing and outfitting revenues remained consistent with 2009 levels, with an increase in manufac- turing volume offset by reduced outfitting work.
Aircraft manufacturing revenues increased 9 percent in 2010, the result of additional deliveries and a more favorable mix of green Gulfstream aircraft.
The decline in aircraft outfitting revenues was associated primarily with the group’s completions work for other original equipment manufacturers (OEMs), reflecting decreased OEM production across the broader business-jet market.
Aircraft services revenues, which include both Gulfstream and Jet Aviation’s maintenance and repair work, fixed-base operations and aircraft management services, increased 15 percent in 2010, reflecting the growing installed base of business-jet aircraft and increased utilization as the business-jet market recovers following the economic downturn.
Revenues from sales of pre-owned aircraft were down slightly from 2009.
The group’s operating earnings improved significantly in 2010 compared with 2009, with improvements in all areas of the group’s portfolio.
The components of the earnings growth were as follows:
## Table 2 ##
The group’s aircraft manufacturing and outfitting earnings were up in 2010 compared with 2009 due to the increase in aircraft manufacturing volume, as well as improved pricing on large-cabin aircraft and mix shift within large-cabin models.
This increase was offset in part by reduced liquidated damages associated with fewer customer defaults.
Margins for these activities were up 190 basis points compared with 2009.
Pre-owned aircraft earnings improved significantly from 2009, when the group wrote down the carrying value of its pre-owned aircraft inventory.
Pricing in the pre-owned market has improved since mid-2009, particularly for large-cabin aircraft, although inventories across the industry remain higher than historic norms.
In 2010, the Aerospace group realized modest profits on its pre-owned sales, took no pre-owned aircraft write-downs and ended the year with no pre-owned aircraft in inventory.
Consistent with the increased volume, aircraft services earnings continued to improve from 2009.
Margins associated with aircraft services were up 70 basis points in 2010 due to improved marketplace pricing.
The group’s operating earnings in 2010 were also favorably impacted by the timing of R&D expenditures and the absence of severance costs associated with workforce reductions in 2009.
As a result of the factors discussed above, the group’s overall operating margins increased 250 basis points in 2010 compared with 2009.  Review of 2009 vs.  2008
## Table 3 ##
The Aerospace group’s revenues decreased in 2009, the result ofadecline in sales of Gulfstream aircraft that was offset in part by the addition of Jet Aviation, which we acquired in the fourth quarter of 2008.
We reduced Gulfstream’s 2009 aircraft production, primarily in the group’s mid-cabin
In summary, our cash flows for each period were as follows:
## Table 4 ##
OPERATING ACTIVITIES Cash provided by operating activities is net income adjusted for certain non-cash items and changes in assets and liabilities.
For 2017 compared to 2016, the $302 million increase in cash provided by operating activities was due to changes to working capital partially offset by adjustments for non-cash items and lower net income.
Tax Reform did not have an impact on our 2017 cash provided by operating activities.
The increase in cash provided by operating activities was driven by increased income before taxes and $1.0 billion receipts of customer deposits.
These increases were partially offset by increased inventory and accounts receivable.
Income taxes paid, net of refunds, in 2017 compared to 2016 were $2.9 billion higher due to higher income before taxes, taxable gains on sales of ASML, and taxes on the ISecG divestiture.
We expect approximately $2.0 billion of additional customer deposits in 2018.
For 2016 compared to 2015, the $2.8 billion increase in cash provided by operating activities was due to adjustments for non-cash items and changes in working capital, partially offset by lower net income.
The adjustments for non-cash items were higher in 2016 primarily due to restructuring and other charges and the change in deferred taxes, partially offset by lower depreciation.
INVESTING ACTIVITIES Investing cash flows consist primarily of capital expenditures; investment purchases, sales, maturities, and disposals; and proceeds from divestitures and cash used for acquisitions.
Our capital expenditures were $11.8 billion in 2017 ($9.6 billion in 2016 and $7.3 billion in 2015).
The decrease in cash used for investing activities in 2017 compared to 2016 was primarily due to higher net activity of available-for sale-investments in 2017, proceeds from our divestiture of ISecG in 2017, and higher maturities and sales of trading assets in 2017.
This activity was partially offset by higher capital expenditures in 2017.
The increase in cash used for investing activities in 2016 compared to 2015 was primarily due to our completed acquisition of Altera, net purchases of trading assets in 2016 compared to net sales of trading assets in 2015, and higher capital expenditures in 2016.
This increase was partially offset by lower investments in non-marketable equity investments.
FINANCING ACTIVITIES Financing cash flows consist primarily of repurchases of common stock, payment of dividends to stockholders, issuance and repayment of short-term and long-term debt, and proceeds from the sale of shares of common stock through employee equity incentive plans.
The increase in cash used for financing activities in 2017 compared to 2016 was primarily due to net long-term debt activity, which was a use of cash in 2017 compared to a source of cash in 2016.
During 2017, we repurchased $3.6 billion of common stock under our authorized common stock repurchase program, compared to $2.6 billion in 2016.
As of December 30, 2017, $13.2 billion remained available for repurchasing common stock under the existing repurchase authorization limit.
We base our level of common stock repurchases on internal cash management decisions, and this level may fluctuate.
Proceeds from the sale of common stock through employee equity incentive plans totaled $770 million in 2017 compared to $1.1 billion in 2016.
Our total dividend payments were $5.1 billion in 2017 compared to $4.9 billion in 2016.
We have paid a cash dividend in each of the past 101 quarters.
In January 2018, our Board of Directors approved an increase to our cash dividend to $1.20 per share on an annual basis.
The board has declared a quarterly cash dividend of $0.30 per share of common stock for Q1 2018.
The dividend is payable on March 1, 2018 to stockholders of record on February 7, 2018.
Cash was used for financing activities in 2016 compared to cash provided by financing activities in 2015, primarily due to fewer debt issuances and the repayment of debt in 2016.
This activity was partially offset by repayment of commercial paper in 2015 and fewer common stock repurchases in 2016.
