Annuities Our Annuities segment provides variable and fixed annuity products of RiverSource Life companies to individual clients.
We provide our variable annuity products through our advisors, and our fixed annuity products are distributed through both affiliated and unaffiliated advisors and financial institutions.
Revenues from our variable annuity products are primarily earned as fees based on underlying account balances, which are impacted by both market movements and net asset flows.
Revenues from our fixed annuity products are primarily earned as net investment income on assets supporting fixed account balances, with profitability significantly impacted by the spread between net investment income earned and interest credited on the fixed account balances.
We also earn net investment income on owned assets supporting reserves for immediate annuities and for certain guaranteed benefits offered with variable annuities and on capital supporting the business.
Intersegment revenues for this segment reflect fees paid by our Asset Management segment for marketing support and other services provided in connection with the availability of variable insurance trust funds (‘‘VIT Funds’’) under the variable annuity contracts.
Intersegment expenses for this segment include distribution expenses for services provided by our Advice & Wealth Management segment, as well as expenses for investment management services provided by our Asset Management segment.
The following table presents the results of operations of our Annuities segment on an operating basis:
## Table 0 ##
NM Not Meaningful.
Our Annuities segment pretax operating income, which excludes net realized gains or losses and the market impact on variable annuity guaranteed benefits (net of hedges and the related DSIC and DAC amortization), increased $4 million, or 1%, to $633 million for the year ended December 31, 2014 compared to $629 million for the prior year primarily due to market appreciation, as well as a benefit from policyholder movement of investments in Portfolio Navigator funds under certain in force variable annuities with living benefit guarantees to the Portfolio Stabilizer funds, partially offset by the impact of unlocking.
The impact of unlocking was a decrease to pretax operating income of $22 million for the year ended December 31, 2014 compared to an increase of $60 million for the prior year.
During the fourth quarter of 2013, we added Portfolio Stabilizer fund options for our in force variable annuities with living benefit guarantees.
During the year ended December 31, 2014, approximately $4.7 billion of account value was moved into these funds, exceeding expectations.
The resulting earnings benefit for the year ended December 31, 2014 was $44 million compared to a benefit of $26 million in the prior year.
We anticipate a very minimal benefit to earnings going forward.
RiverSource variable annuity account balances increased 2% to $77.0 billion at December 31, 2014 compared to the prior year due to market appreciation, partially offset by net outflows of $1.7 billion.
RiverSource fixed annuity account balances declined 8% to $12.1 billion at December 31, 2014 compared to the prior year reflecting elevated surrenders on products sold through third parties where crediting rates have reset lower.
The change in crediting rates decreased the level of spread compression for the year ended December 31, 2014.
All of the five-year guarantee block totaling $4.1 billion has been re-priced as of December 31, 2014.
THE GOLDMAN SACHS GROUP, INC.  AND SUBSIDIARIES Notes to Consolidated Financial Statements Receivables from Customers and Counterparties.
Receivables from customers and counterparties at fair value primarily consist of transfers of assets accounted for as secured loans rather than purchases.
The significant inputs to the valuation of such receivables are commodity prices, interest rates, the amount and timing of expected future cash flows and funding spreads.
As of both December 2017 and December 2016, the firm’s level 3 receivables from customers and counterparties were not material.
Deposits.
The significant inputs to the valuation of time deposits are interest rates and the amount and timing of future cash flows.
The inputs used to value the embedded derivative component of hybrid financial instruments are consistent with the inputs used to value the firm’s other derivative instruments.
See Note 7 for further information about derivatives and Note 14 for further information about deposits.
The firm’s deposits that are classified in level 3 are hybrid financial instruments.
As the significant unobservable inputs used to value hybrid financial instruments primarily relate to the embedded derivative component of these deposits, these inputs are incorporated in the firm’s derivative disclosures related to unobservable inputs in Note 7.
Transfers Between Levels of the Fair Value Hierarchy Transfers between levels of the fair value hierarchy are reported at the beginning of the reporting period in which they occur.
There were no transfers of other financial assets and financial liabilities between level 1 and level 2 during both 2017 and 2016.
See “Level 3 Rollforward” below for information about transfers between level 2 and level 3.
Level 3 Rollforward The table below presents a summary of the changes in fair value for level 3 other financial assets and financial liabilities accounted for at fair value.
## Table 1 ##
In the table above: ‰ Changes in fair value are presented for all other financial assets and financial liabilities that are classified in level 3 as of the end of the period.
‰ Net unrealized gains/(losses) relates to instruments that were still held at period-end.
‰ If a financial asset or financial liability was transferred to level 3 during a reporting period, its entire gain or loss for the period is classified in level 3.
For level 3 other financial assets, increases are shown as positive amounts, while decreases are shown as negative amounts.
For level 3 other financial liabilities, increases are shown as negative amounts, while decreases are shown as positive amounts.
‰ Level 3 other financial assets and financial liabilities are frequently economically hedged with cash instruments and derivatives.
Accordingly, gains or losses that are classified in level 3 can be partially offset by gains or losses attributable to level 1, 2 or 3 cash instruments or derivatives.
As a result, gains or losses included in the level 3 rollforward below do not necessarily represent the overall impact on the firm’s results of operations, liquidity or capital resources.
PART I The following table details the growth in global weighted average berths and the global, North American and European cruise guests over the past five years:
## Table 2 ##
(1) Source: Our estimates of the number of global cruise guests and the weighted-average supply of berths marketed globally are based on a combination of data that we obtain from various publicly available cruise industry trade information sources including Seatrade Insider, Cruise Industry News and Cruise Line International Association (“CLIA”).
In addition, our estimates incorporate our own statistical analysis utilizing the same publicly available cruise industry data as a base.
(2) Source: Cruise Line International Association based on cruise guests carried for at least two consecutive nights for years 2009 through 2012.
Year 2013 amounts represent our estimates (see number 1 above).
Includes the United States of America and Canada.
(3) Source: CLIA Europe, formerly European Cruise Council, for years 2009 through 2012.
Year 2013 amounts represent our estimates (see number 1 above).
North America The majority of cruise guests are sourced from North America, which represented approximately 56% of global cruise guests in 2013.
The compound annual growth rate in cruise guests sourced from this market was approximately 3.2% from 2009 to 2013.
Europe Cruise guests sourced from Europe represented approximately 30% of global cruise guests in 2013.
The compound annual growth rate in cruise guests sourced from this market was approximately 6.0% from 2009 to 2013.
Other Markets In addition to expected industry growth in North America and Europe, we expect the Asia/Pacific region to demonstrate an even higher growth rate in the near term, although it will continue to represent a relatively small sector compared to North America and Europe.
Based on industry data, cruise guests sourced from the Asia/Pacific region represented approximately 4.5% of global cruise guests in 2013.
The compound annual growth rate in cruise guests sourced from this market was approximately 15% from 2011 to 2013.
COMPETITION We compete with a number of cruise lines.
Our principal competitors are Carnival Corporation & plc, which owns, among others, Aida Cruises, Carnival Cruise Lines, Costa Cruises, Cunard Line, Holland America Line, Iberocruceros, P&O Cruises and Princess Cruises; Disney Cruise Line; MSC Cruises; Norwegian Cruise Line and Oceania Cruises.
Cruise lines compete with other vacation alternatives such as land-based resort hotels and sightseeing destinations for consumers’ leisure time.
Demand for such activities is influenced by political and general economic conditions.
Companies within the vacation market are dependent on consumer discretionary spending.
OPERATING STRATEGIES Our principal operating strategies are to: ·protect the health,safety and security of our guests and employees and protect the environment in which our vessels and organization operate, ·strengthen and support our human capital in order to better serve our global guest base and grow our business, ·further strengthen our consumer engagement in order to enhance our revenues, ·increase the awareness and market penetration of our brands globally, ·focus on cost efficiency,manage our operating expenditures and ensure adequate cash and liquid- ity,with the overall goal of maximizing our return on invested capital and long-term shareholder value, ·strategically invest in our fleet through the revital- ization and maintenance of existing ships and the transfer of key innovations across each brand,while prudently expanding our fleet with new state-of- the-art cruise ships, ·capitalize on the portability and flexibility of our ships by deploying them into those markets and itineraries that provide opportunities to optimize returns,while lcontinuing our focus on existing key markets, ·further enhance our technological cap abilities to service customer preferences and expectations in an innovative manner,while supporting our strategic focus on profitability,and
Foreign tax differentials represent the differences between foreign earnings subject to foreign tax rates lower than the U. S.  federal statutory tax rate.
Some of our foreign earnings are subject to local country tax rates that are below the U. S.  federal statutory rate and include tax holidays and incentives.
As a result of the reduction in the federal corporate income tax rates under the Tax Act our effective non-U.
S.  tax rate is now closer to our blended current year U. S.  statutory rate of 24.5%.
Tax on foreign repatriated earnings includes benefits and costs related to U. S.  and additional foreign taxation on the current and future repatriation of foreign earnings and a U. S.  benefit for related foreign tax credits.
As a result of the Tax Act, the impact on our effective rate from repatriations and credits has been significantly reduced.
Due to the effective date of provisions under the Tax Act, certain benefits reported in fiscal year 2018 will not recur in fiscal year 2019.
The Tax Act repeals the domestic production activities deduction, effective for our fiscal 2019 tax year, and lowers the benefit taken in fiscal year 2018.
In fiscal year 2018, we recognized a tax benefit of $35.7, net of reserves for uncertain tax positions, and a corresponding decrease in net deferred tax liabilities resulting from the restructuring of several foreign subsidiaries.
During the first quarter of fiscal year 2017, we adopted new accounting guidance that requires excess tax benefits and deficiencies from share-based compensation to be recognized in the consolidated income statements rather than in additional paid-in capital on the consolidated balance sheets.
As a result of applying this change prospectively, we recognized $21.5 and $17.6 of excess tax benefits in our provision for income taxes during fiscal year 2018 and 2017, respectively.
Primarily due to the impact of the Tax Act and the restructuring benefit, our effective tax rate was 26% for the twelve months ended 30 September 2018.
In 2017, the effective tax rate was impacted by a tax election made with respect to a Chilean holding company resulting in an income tax benefit of $111.4 on tax losses related to investments in Chile.
The effective tax rate was also impacted by a goodwill impairment charge of $145.3 for which no tax benefits were available.
See Note 10, Goodwill, for additional information regarding the impairment charge.
In 2016, the effective tax rate was impacted by tax costs of $51.8 incurred in anticipation of the tax-free spin-off of Versum, primarily for a dividend declared during the third quarter of 2016 to repatriate $443.8 from a subsidiary in South Korea to the U. S.  Previously, most of these foreign earnings were considered to be indefinitely reinvested.
In addition, a tax benefit was not available on a significant portion of the business separation costs.
See Note 4, Materials Technologies Separation, for additional information.
The significant components of deferred tax assets and liabilities are as follows:

(1) Our fiscal year ends on the Saturday closest to December 31.
Fiscal 2014, which ended January 3, 2015, included 53 weeks, with the 53rd week falling in the fourth fiscal quarter.
Fiscal 2013, which ended December 28, 2013, included 52 weeks.
For certain of our sales arrangements, where revenue is recognized over time, the 53rd week in fiscal 2014 resulted in incremental fourth quarter revenue of approximately $15 million, which is net of certain other immaterial adjustments to fourth quarter revenue.
(2) During the first quarter of fiscal 2013, we recorded a $33.7 million benefit for income taxes from the release of an uncertain tax position, including related interest and penalties, and a 5.9 million tax benefit from the retroactive enactment of the fiscal 2012 United States federal research tax credit.
For an additional description of, and disclosures regarding, our income tax provision or benefit, see Note 6 in the notes to consolidated financial statements.
(3) During the quarter ended January 3, 2015, we recorded a benefit for income taxes of $8.1 million resulting from the enactment of the United States federal research tax credit in December 2014.

Item 9A.
Controls and Procedures Evaluation of Disclosure Controls and Procedures As required by Rule 13a-15 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, under the supervision and with the participation of our management, including our Chief Executive Officer, or CEO, and our Chief Financial Officer, or CFO, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of January 3, 2015.
The evaluation of our disclosure controls and procedures included a review of our processes and the effect on the information generated for use in this Annual Report on Form 10-K.
In the course of this evaluation, we sought to identify any material weaknesses in our disclosure controls and procedures, to determine whether we had identified any acts of fraud involving personnel who have a significant role in our disclosure controls and procedures, and to confirm that any necessary corrective action, including process improvements, was taken.
This type of evaluation is done every fiscal quarter so that our conclusions concerning the effectiveness of these controls can be reported in our periodic reports filed with the SEC.
The overall goals of these evaluation activities are to monitor our disclosure controls and procedures and to make modifications as necessary.
We intend to maintain these disclosure controls and procedures, modifying them as circumstances warrant.
Ending membership was as follows at December 31, 2009 and 2008:
## Table 5 ##
(a) The Commercial segment provides a full range of insured specialty products including dental, vision, and other supplemental products.
Members included in these products may not be unique to each product since members have the ability to enroll in multiple products.
These tables of financial data should be reviewed in connection with the discussion that follows.
Summary Net income was $1,039.7 million, or $6.15 per diluted common share, in 2009 compared to $647.2 million, or $3.83 per diluted common share, in 2008.
The year-over-year increase primarily reflects higher operating earnings in our Government segment as a result of significantly lower prescription drug claims expenses associated with our Medicare stand-alone PDP products.
Premium Revenues and Medical Membership Premium revenues increased $1.8 billion, or 6.6%, to $29.9 billion for 2009, compared to $28.1 billion for 2008 primarily due to higher premium revenues in the Government segment.
Premium revenues reflected changes in membership and increases in average per member premiums.
Items impacting average per member premiums included changes in premium rates as well as changes in the geographic mix of membership, the mix of product offerings, and the mix of benefit plans selected by our membership.
Government segment premium revenues increased $1.8 billion, or 8.8%, to $22.8 billion for 2009 compared to $21.0 billion for 2008 primarily attributable to higher average Medicare Advantage membership and an increase in per member premiums partially offset by a decrease in our Medicare stand-alone PDP membership.
