Citigroup's history dates back to the founding of the City Bank of New York in 1812. Citigroup's original corporate predecessor was incorporated in 1988 under the laws of the State of Delaware. Following a series of transactions over a number of years, Citigroup Inc. was formed in 1998 upon the merger of Citicorp and Travelers Group Inc.

Citigroup is a global diversified financial services holding company, whose businesses provide consumers, corporations, governments and institutions with a broad range of financial products and services, including consumer banking and credit, corporate and investment banking, securities brokerage, trade and securities services and wealth management. Citi has approximately 200 million customer accounts and does business in more than 160 countries and jurisdictions.

At December 31, 2014, Citi had approximately 241,000 full-time employees, compared to approximately 251,000 full-time employees at December 31, 2013.

Citigroup currently operates, for management reporting purposes, via two primary business segments: Citicorp, consisting of Citi's Global Consumer Banking businesses and Institutional Clients Group ; and Citi Holdings, consisting of businesses and portfolios of assets that Citigroup has determined are not central to its core Citicorp businesses. For a further description of the business segments and the products and services they provide, see "Citigroup Segments" below, "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 3 to the Consolidated Financial Statements.

Throughout this report, "Citigroup," "Citi" and "the Company" refer to Citigroup Inc. and its consolidated subsidiaries.

EXECUTIVE SUMMARY

Steady Progress on Execution Priorities Despite Continued Challenging Operating Environment

As discussed further throughout this Form 10-K, Citi's 2014 results reflected a continued challenging operating environment for Citi and its businesses in several respects, including:

In addition, as part of its execution priorities to improve its efficiency and reduce expenses, Citi incurred higher repositioning costs during the year, which also impacted its 2014 results of operations.

Despite these difficult decisions and challenges, Citi continued to make progress on its execution priorities in 2014, including:

While making progress on these initiatives in 2014, Citi expects the operating environment in 2015 to remain challenging. Regulatory changes and requirements continue to create uncertainties for Citi and its businesses. While the U.S. economy continues to improve, it remains susceptible to global events and volatility. The economic and fiscal situations of several European countries remain fragile, and geopolitical tensions in the region have added to the uncertainties. Although most emerging market economies continue to grow, growth has slowed in some markets and these economies are also susceptible to outside macroeconomic events and challenges. The frequency with which legal and regulatory proceedings are initiated against

financial institutions, and the severity of the remedies sought in these proceedings, has increased substantially over the past several years, including 2014. Financial institutions also remain a target for an increasing number of cybersecurity attacks. For a more detailed discussion of these and other risks that could impact Citi's businesses, results of operations and financial condition during 2015, see each respective business' results of operations, "Risk Factors" and "Managing Global Risk" below.

While Citi may not be able to completely control these and other factors affecting its operating environment in 2015, it will remain focused on its execution priorities, as described above, and remains committed to achieving its 2015 financial targets for Citicorp's operating efficiency ratio and Citigroup's return on assets.

2014 Summary Results

Citigroup

Citigroup reported net income of $7.3 billion or $2.20 per diluted share, compared to $13.7 billion or $4.35 per share in 2013. In 2014, Citi's results included negative $390 million (negative $240 million after-tax) of CVA/DVA, compared to negative $342 million (negative $213 million after-tax) in 2013 (for additional information, including Citi's adoption of funding valuation adjustments, or FVA, in 2014, see Note 25 to the Consolidated Financial Statements). Citi's results in 2014 also included a charge of $3.8 billion ($3.7 billion after-tax) related to the mortgage settlement announced in July 2014 regarding certain of Citi's legacy residential mortgage-backed securities and CDO activities, recorded in Citi Holdings. Results in 2014 further included a tax charge of approximately $210 million related to corporate tax reforms enacted in two states, compared to a tax benefit of $176 million in 2013 related to the resolution of certain tax audit items, both recorded in Corporate/Other . In addition, Citi's 2013 results included a net fraud loss in Mexico of $360 million ($235 million after-tax) recorded in ICG, and a $189 million after-tax benefit related to the divestiture of Credicard, Citi's non-Citibank branded cards and consumer finance business in Brazil (Credicard), recorded in Corporate/Other .

Excluding these items, Citi reported net income of $11.5 billion in 2014, or $3.55 per diluted share, compared to $13.8 billion, or $4.37 per share, in the prior year. The 16% decrease from 2013 was driven by higher expenses, a lower net loan loss reserve release and a higher effective tax rate due primarily to non-deductible legal and related expenses incurred during the year (for additional information, see Note 9 to the Consolidated Financial Statements), partially offset by increased revenues in Citi Holdings and a decline in net credit losses. (Citi's results of operations excluding the impacts of CVA/DVA, the mortgage settlement, the tax items, the net fraud loss and the Credicard divestiture are non-GAAP financial measures. Citi believes the presentation of its results of operations excluding these impacts provides a more

meaningful depiction for investors of the underlying fundamentals of its businesses.)

Citi's revenues, net of interest expense, were $76.9 billion in 2014, up 1% versus the prior year. Excluding CVA/DVA, revenues were $77.3 billion, also up 1% from 2013, as revenues rose 28% in Citi Holdings, partially offset by a 1% decline in Citicorp. Net interest revenues of $48.0 billion were 3% higher than 2013, mostly driven by lower funding costs. Excluding CVA/DVA, non-interest revenues were $29.3 billion, down 2% from 2013, driven by lower revenues in ICG and GCB in Citicorp, partially offset by higher non-interest revenues in Citi Holdings.

Expenses

Citigroup expenses increased 14% versus 2013 to $55.1 billion. Excluding the impact of the mortgage settlement in 2014 and the net fraud loss in 2013, operating expenses increased 7% versus the prior year to $51.3 billion driven by higher legal and related expenses ($5.8 billion compared to $3.0 billion in the prior year) and repositioning costs ($1.6 billion compared to $590 million in the prior year).

Excluding the legal and related expenses, net fraud loss in 2013, repositioning charges and the impact of foreign exchange translation into U.S. dollars for reporting purposes (FX translation), which lowered reported expenses by approximately $503 million in 2014 compared to 2013, expenses were roughly unchanged at $43.9 billion as repositioning savings, expense reductions in Citi Holdings and other productivity initiatives were fully offset by the impact of higher regulatory and compliance and volume-related costs. (Citi's results of operations excluding the impact of legal and related expenses, repositioning charges and FX translation are non-GAAP financial measures. Citi believes the presentation of its results of operations excluding these impacts provides a more meaningful depiction for investors of the underlying fundamentals of its businesses.)

Excluding the impact of the net fraud loss in 2013, Citicorp's expenses were $47.3 billion, up 12% from the prior year, primarily reflecting higher legal and related expenses, largely in Corporate/Other ($4.8 billion compared to $432 million in 2013), higher repositioning costs ($1.6 billion compared to $547 million in 2013), higher regulatory and compliance costs and higher volume-related costs, partially offset by efficiency savings. Excluding the impact of the mortgage settlement in 2014, Citi Holdings' expenses were $4.0 billion, down 34% from 2013, reflecting lower legal and related expenses as well as the ongoing decline in Citi Holdings' assets.

Credit Costs and Allowance for Loan Losses

Citi's total provisions for credit losses and for benefits and claims of $7.5 billion declined 12% from 2013. Excluding the impact of the mortgage settlement in 2014, total provisions for credit losses and for benefits and claims declined 13% to $7.4 billion versus the prior year. Net credit losses of $9.0 billion were down 14% versus the prior year. Consumer net credit losses declined 15% to $8.7 billion, reflecting continued improvements in the North America mortgage portfolio within Citi Holdings, as well as North America Citi-branded cards and Citi retail services in Citicorp. Corporate net credit losses increased 43% to $288 million in 2014. Corporate net credit losses in 2014 included approximately $113 million of incremental net credit losses related to the Pemex supplier program in Mexico (for additional information regarding the Pemex supplier program, see " Institutional Clients Group " below).

The net release of allowance for loan losses and unfunded lending commitments was $2.3 billion in 2014. Excluding the impact of the mortgage settlement in 2014, the net release of allowance for loan losses and unfunded lending commitments was $2.4 billion in 2014 compared to a $2.8 billion release in the prior year. Citicorp's net reserve release increased to $1.4 billion from $736 million in 2013 due to higher reserve releases in North America GCB and ICG , reflecting improved credit trends . Citi Holdings' net reserve release, excluding the impact of the mortgage settlement in 2014, decreased 53% to $958 million, primarily due to lower releases related to the North America mortgage portfolio (which also had lower net credit losses).

Citigroup's total allowance for loan losses was $16.0 billion at year end, or 2.50% of total loans, compared to $19.6 billion, or 2.97%, at the end of 2013. The decline in the total allowance for loan losses reflected the continued wind down of Citi Holdings and overall continued improvement in the credit quality of Citi's loan portfolios. The consumer allowance for loan losses was $13.6 billion, or 3.68% of total consumer loans, at year end, compared to $17.1 billion, or 4.34% of total loans, at the end of 2013. The consumer 90+ days past due delinquencies were $4.6 billion, or 1.27% of consumer loans, at year end, a decline from $5.7 billion or 1.49% of loans in the prior year. Total non-accrual assets fell to $7.4 billion, a 22% reduction compared to 2013. Corporate non-accrual loans declined 38% to $1.2 billion, while Consumer non-accrual loans declined 17% to $5.9 billion, both reflecting the continued improvement in credit trends.

Capital

Despite the challenging operating environment and elevated legal and related expenses during 2014, Citi was able to maintain its regulatory capital, primarily through net income and the further reduction of its DTAs. Citigroup's Basel III Tier 1 Capital and Common Equity Tier 1 Capital ratios, on a fully implemented basis, were 11.5% and 10.6% as of December 31, 2014, respectively, compared to 11.3% and 10.6% as of December 31, 2013 (all based on the Advanced Approaches for determining risk-weighted assets). Citigroup's estimated Basel III Supplementary Leverage ratio as of December 31, 2014 was 6.0% compared to 5.4% as of

December 31, 2013, each based on the revised final U.S. Basel III rules. For additional information on Citi's capital ratios and related components, see "Capital Resources" below.

Citicorp

Citicorp net income decreased 32% from the prior year to $10.7 billion. CVA/DVA, recorded in ICG , was negative $343 million (negative $211 million after-tax) in 2014, compared to negative $345 million (negative $214 million after-tax) in the prior year (for a summary of CVA/DVA by business within ICG , see " Institutional Clients Group " below).

Excluding CVA/DVA as well as the impact of the net fraud loss in Mexico, the tax items and the divestiture of Credicard noted above, Citicorp's net income was $11.1 billion, down 29% from the prior year, as higher expenses, a higher effective tax rate and lower revenues were partially offset by continued improvement in credit costs.

Citicorp revenues, net of interest expense, decreased 1% from the prior year to $71.1 billion. Excluding CVA/DVA, Citicorp revenues were $71.4 billion in 2014, also down 1% from the prior year. GCB revenues of $37.8 billion decreased 1% versus the prior year. North America GCB revenues declined 1% to $19.6 billion driven by lower retail banking revenues, partially offset by higher revenues in Citi-branded cards and Citi retail services. Retail banking revenues declined 9% to $4.9 billion versus the prior year, primarily reflecting lower mortgage origination revenues and spread compression in the deposits portfolios, partially offset by volume-related growth and gains from branch sales during the year. Citi-branded cards revenues of $8.3 billion were up 1% versus the prior year as purchase sales grew and an improvement in spreads driven by a reduction in promotional rate balances mostly offset the impact of lower average loans. Citi retail services revenues increased 4% to $6.5 billion, mainly reflecting the impact of the Best Buy portfolio acquisition in September 2013, partially offset by continued declines in fee revenues primarily reflecting higher yields and improving credit and the resulting increase in contractual partner payments. North America GCB average deposits of $171 billion grew 3% year-over-year and average retail loans of $46 billion grew 9%. Average card loans of $110 billion increased 2%, and purchase sales of $252 billion increased 5% versus the prior year. For additional information on the results of operations of North America GCB for 2014, see " Global Consumer Banking-North America GCB " below.

International GCB revenues (consisting of EMEA GCB , Latin America GCB and Asia GCB ) decreased 2% versus the prior year to $18.1 billion. Excluding the impact of FX translation, international GCB revenues rose 2% from the prior year, driven by 4% growth in Latin America GCB and 1% growth in Asia GCB , partially offset by a 1% decline in EMEA GCB (for the impact of FX translation on 2014 results of operations for each of EMEA GCB, Latin America GCB and Asia GCB , see the table accompanying the discussion of each respective business' results of operations below). The growth in international GCB revenues, excluding the impact of FX translation, mainly reflected volume growth in all regions , partially offset by spread compression, the ongoing impact of regulatory changes and the repositioning of Citi's franchise in

Korea , as well as market exits in EMEA GCB in 2013. For additional information on the results of operations of EMEA GCB, Latin America GCB and Asia GCB for 2014, see " Global Consumer Banking " below. Year-over-year, international GCB average deposits increased 2%, average retail loans increased 7%, investment sales increased 8%, average card loans increased 2% and card purchase sales increased 5%, all excluding the impact of Credicard's results in the prior year period and FX translation.

ICG revenues were $33.3 billion in 2014, down 1% from the prior year. Excluding CVA/DVA, ICG revenues were $33.6 billion, also down 1% from the prior year. Banking revenues of $17.0 billion, excluding CVA/DVA and the impact of mark-to-market gains/(losses) on hedges related to accrual loans within corporate lending (see below), increased 5% from the prior year, primarily reflecting growth in investment banking, corporate lending and private bank revenues. Investment banking revenues increased 7% versus the prior year, driven by an 11% increase in advisory revenues to $949 million and an 18% increase in equity underwriting to $1.2 billion. Debt underwriting revenues of $2.5 billion were largely unchanged from 2013. Private bank revenues, excluding CVA/DVA, increased 7% to $2.7 billion from the prior year, driven by increased client volumes and growth in investment and capital markets products, partially offset by spread compression. Corporate lending revenues rose 52% to $1.9 billion, including $116 million of mark-to-market gains on hedges related to accrual loans compared to a $287 million loss in the prior year. Excluding the mark-to-market impact on hedges related to accrual loans in both periods, corporate lending revenues rose 15% versus the prior year to $1.7 billion, primarily reflecting growth in average loans and improved funding costs. Treasury and trade solutions revenues increased by 1% versus the prior year to $7.9 billion as volume and fee growth was largely offset by the impact of spread compression globally.

Markets and securities services revenues of $16.5 billion, excluding CVA/DVA, decreased 8% from the prior year. Fixed income markets revenues of $11.8 billion, excluding CVA/DVA, decreased 11% from the prior year, reflecting weakness across rates and currencies, credit markets and municipals due to challenging trading conditions, partially offset by increased securitized products and commodities revenues. The first half of 2013 included a strong performance in rates and currencies, driven in part by the impact of quantitative easing globally. Equity markets revenues of $2.8 billion, excluding CVA/DVA, declined 1% versus the prior year, mostly reflecting weakness in cash equities in EMEA driven by volatility in Europe, partially offset by strength in prime finance. Securities services revenues of $2.3 billion increased 3% versus the prior year primarily due to increased volumes, assets under custody and overall client activity. For additional information on the results of operations of ICG for 2014, see " Institutional Clients Group " below.

Corporate/Other revenues decreased to $47 million from $121 million in the prior year, driven mainly by lower revenues from sales of available-for-sale securities as well as hedging activities. For additional information on the results of

operations of Corporate/Other in 2014, see " Corporate/Other " below.

Citicorp end-of-period loans were roughly unchanged at $572 billion, with 1% growth in corporate loans offset by a 2% decline in consumer loans. Excluding the impact of FX translation, Citicorp loans grew 3%, with 4% growth in corporate loans and 2% growth in consumer loans.

Citi Holdings

Citi Holdings' net loss was $3.4 billion in 2014 compared to a net loss of $1.9 billion in 2013. CVA/DVA was negative $47 million (negative $29 million after-tax) in 2014, compared to positive $3 million (positive $1 million after-tax) in the prior year. Excluding the impact of CVA/DVA and the mortgage settlement in 2014, Citi Holdings' net income was $385 million, reflecting lower expenses, higher revenues and lower net credit losses, partially offset by a lower net loan loss reserve release.

Citi Holdings' revenues increased 27% to $5.8 billion from the prior year. Excluding CVA/DVA, Citi Holdings' revenues increased 28% to $5.9 billion from the prior year. Net interest revenues increased 11% year-over-year to $3.5 billion, largely driven by lower funding costs. Non-interest revenues, excluding CVA/DVA, increased 68% to $2.3 billion from the prior year, primarily driven by higher gains on assets sales and the absence of repurchase reserve builds for representation and warranty claims in 2014. For additional information on the results of operations of Citi Holdings in 2014, see "Citi Holdings" below.

Citi Holdings' assets were $98 billion, 16% below the prior year, and represented approximately 5% of Citi's total GAAP assets and 14% of its risk-weighted assets under Basel III as of year end (based on the Advanced Approaches for determining risk-weighted assets).

2014 vs. 2013

Net income increased by 13% due to lower net credit losses, higher loan loss reserve releases and lower expenses, partially offset by lower revenues.

Revenues decreased 1%, with lower revenues in retail banking, partially offset by higher revenues in Citi-branded cards and Citi retail services. Net interest revenue increased 3% primarily due to an increase in average loans in Citi retail services driven by the Best Buy portfolio acquisition in September 2013 and continued volume growth in retail banking, which more than offset lower average loans in Citi-branded cards. Non-interest revenue decreased 22%, driven by lower mortgage origination revenues due to significantly lower U.S. mortgage refinancing activity and a continued decline in revenues in Citi retail services, primarily reflecting improving credit and the resulting impact on contractual partner payments, partially offset by a 5% increase in total card purchase sales to $252 billion and gains during the year from branch sales (approximately $130 million).

Retail banking revenues of $4.9 billion decreased 9% due to the lower mortgage origination revenues and spread compression in the deposit portfolios, which began to abate during the latter part of the year, partially offset by continued volume-related growth and the gains from branch sales. Consistent with GCB 's strategy, during 2014, NA GCB closed or sold over 130 branches (a 14% decline from the prior year), with announced plans to sell or close an additional 60 branches in early 2015. Average loans of $46 billion increased 9% and average deposits of $171 billion increased 3%.

Cards revenues increased 2% as average loans of $110 billion increased 3% versus 2013. In Citi-branded cards, revenues increased 1% as a 4% increase in purchase sales and higher net interest spreads, driven by the continued reduction of promotional balances in the portfolio, mostly offset lower average loans (3% decline from 2013). The decline in average loans was driven primarily by the reduction in promotional balances, and to a lesser extent, increased customer payment rates during the year. In addition, while the business experienced modest full rate loan growth during 2014, growth in full rate loan balances began to slow during the latter part of the year. Combined with the continued reduction in promotional balances, NA GCB could experience pressure on full rate loan growth during 2015.

Citi retail services revenues increased 4% primarily due to a 12% increase in average loans driven by the Best Buy acquisition, partially offset by continued declines in fee revenues primarily reflecting higher yields and improving credit and the resulting increase in contractual partner payments. Citi retail services revenues also benefited from lower funding costs, partially offset by a decline in net interest spreads due to a higher percentage of promotional balances within the portfolio. Purchase sales in Citi retail services increased 7% from 2013, driven by the acquisition of the Best Buy portfolio.

With respect to both cards portfolios, as widely publicized, U.S. gas prices declined during 2014, particularly in the fourth quarter. The decline in gas prices has negatively impacted purchase sales in the fuel portfolios, particularly in Citi retail services, and consumer savings from lower gas

prices may not result in higher spending in other spend categories. NA GCB will continue to monitor trends in this area going into 2015.

Expenses decreased 2% as ongoing cost reduction initiatives were partially offset by higher repositioning charges, increased investment spending and an increase in Citi retail services expenses due to the impact of the Best Buy portfolio acquisition. Cost reduction initiatives included the ongoing repositioning of the mortgage business due to the decline in mortgage refinancing activity, as well as continued rationalization of the branch footprint, including reducing the number of overall branches, as discussed above.

Provisions decreased 18% due to lower net credit losses (9%) and higher loan loss reserve releases (21%). Net credit losses declined in Citi-branded cards (down 14% to $2.2 billion) and in Citi retail services (down 2% to $1.9 billion). The loan loss reserve release increased to $1.2 billion due to the continued improvement in Citi-branded cards, partially offset by a lower loan loss reserve release in Citi retail services due to reserve builds for new loans originated in the Best Buy portfolio. Given the improvement in credit within the cards portfolios during 2014, NA GCB would not expect to see similar levels of loan loss reserve releases in 2015.

2013 vs. 2012

Net income decreased 14%, mainly driven by lower revenues and lower loan loss reserve releases, partially offset by lower net credit losses and expenses.

Revenues decreased 6% primarily due to lower retail banking revenues. The decline in retail banking revenues was primarily due to lower mortgage origination revenues driven by the significantly lower U.S. mortgage refinancing activity and ongoing spread compression in the deposit portfolios, partially offset by growth in average deposits, average commercial loans and average retail loans.

Cards revenues increased 1%. In Citi-branded cards, revenues were unchanged as continued improvement in net interest spreads, reflecting higher yields as promotional balances represented a smaller percentage of the portfolio total as well as lower funding costs, were offset by a decline in average loans. Citi retail services revenues increased 3% primarily due to the acquisition of the Best Buy portfolio, partially offset by improving credit and the resulting impact on contractual partner payments.

Expenses decreased 3%, primarily due to lower legal and related costs and repositioning savings, partially offset by higher mortgage origination costs and expenses in cards as a result of the Best Buy portfolio acquisition.

Provisions increased 7%, as lower net credit losses in the Citi-branded cards and Citi retail services portfolios were offset by lower loan loss reserve releases ($1.0 billion in 2013 compared to $2.4 billion in 2012), primarily related to cards, as well as reserve builds for new loans originated in the Best Buy portfolio.
