MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

SECOND QUARTER 2011 EXECUTIVE SUMMARY

Citigroup

Citigroup reported second quarter of 2011 net income of $3.3 billion, or $1.09 per diluted share. Citigroup's income increased by 24%, or $644 million, from the second quarter of 2010, as a significant decline in credit costs more than offset the impact of lower revenues and an increase in operating expenses as compared to the prior-year period.

Citigroup revenues, net of interest expense, were $20.6 billion, down $1.4 billion, or 7%, from the second quarter of 2010 as growth in international Regional Consumer Banking and Transaction Services was more than offset by lower revenues in Citi Holdings, Securities and Banking and North America Regional Consumer Banking . Net interest revenues of $12.1 billion were 13% lower than the prior-year period, largely due to continued declining loan balances and lower interest-earnings assets in Citi Holdings. Non-interest revenues were $8.5 billion, up 4% from the prior-year period, principally driven by realized gains on asset sales in the Special Asset Pool in Citi Holdings, including $511 million of pre-tax gains realized in the second quarter of 2011 on the sale of assets transferred out of held-to-maturity in the first quarter of 2011.

Operating Expenses

Citigroup expenses increased $1.1 billion, or 9%, year-over-year to $12.9 billion. Excluding the impact of the UK bonus tax of approximately $400 million in the second quarter of 2010, expenses increased by nearly $1.5 billion, or 13%, year-over-year. Approximately one-third of this 13% increase resulted from the impact of foreign exchange in the translation of local currency results into U.S. dollars (as used throughout this Form 10-Q, FX translation) and another one-third was related to higher legal and related costs. The remaining one-third was driven by the net impact of investment spending, which was partially offset by ongoing productivity savings.

For the first half of 2011, Citigroup expenses were $25.3 billion, up $2.3 billion from the prior-year period, excluding the impact of the UK bonus tax in the second quarter of 2010. Nearly 70% of this increase, or approximately $1.6 billion, resulted from the impact of FX translation and higher legal and related costs in the first half of 2011, as compared to the first half of 2010. The remaining increase of roughly $700 million was primarily driven by investment spending, partially offset by continued productivity savings. The impact of FX translation and legal and related costs will likely continue to affect Citigroup's operating expenses in the second half of 2011 and will remain difficult to predict. Citi currently believes, however, that operating expenses will remain elevated for the remainder of 2011.

Citicorp expenses of $10.1 billion in the second quarter of 2011 grew 10% from the second quarter of 2010. Excluding the UK bonus tax in the second quarter of 2010, expenses were up 14% year-over-year. Over a quarter of this 14% increase resulted from the impact of FX translation, and the remainder was primarily driven by investment spending as Citi continues to execute its strategy to increase revenues and operating income in its business units.

Citi Holdings expenses were down 9% year-over-year to $2.2 billion, principally due to the continued decline in assets and thus lowered operating expenses, offset by an increase in legal and related costs.

Credit Costs

Citigroup total provisions for credit losses and for benefits and claims of $3.4 billion declined $3.3 billion, or 49%, from the prior-year period. Net credit losses of $5.1 billion were down $2.8 billion, or 35%, from the second quarter of 2010. Consumer net credit losses declined $2.7 billion, or 36%, to $4.8 billion, driven by continued improvement in credit in North America Citi-branded cards in Citicorp, and retail partner cards and residential real estate lending in Citi Holdings. Corporate net credit losses decreased $123 million year-over-year to $349 million, due in part to lower volume of loan sales.

The net release of allowance for loan losses and unfunded lending commitments was $2.0 billion in the second quarter of 2011, compared to a net release of $1.5 billion in the second quarter of 2010. More than half of the net credit reserve release in the second quarter of 2011, or $1.1 billion, was attributable to Citi Holdings. The $914 million net credit release in Citicorp was up from $665 million in the prior-year period and was due primarily to higher net releases in Citi-branded cards, partially offset by lower releases in international Regional Consumer Banking and the Corporate portfolio. Citi continues to expect international Regional Consumer Banking and Corporate credit costs in Citicorp to increase, reflecting growing loan portfolios.

Of the $2.0 billion net reserve release in the second quarter of 2011, $1.5 billion related to Consumer and was mainly driven by North America Citi-branded cards and retail partner cards. The $456 million net Corporate reserve release reflected continued improvement in Corporate credit trends, partially offset by the growth in the Corporate loan portfolio. The release reflected lower expected loan losses inherent in the remaining loan portfolios.

Capital and Loan Loss Reserve Positions

Citigroup's Tier 1 Capital ratio was 13.6% at quarter-end, and its Tier 1 Common ratio was 11.6%.

Citigroup's total allowance for loan losses was $34.4 billion at quarter-end, or 5.35%, of total loans, down from $46.2 billion, or 6.72%, in the prior-year period. The decline in the total allowance for loan losses reflected asset sales, lower non-accrual loans, and overall continued improvement in the credit quality of the loan portfolio.

The Consumer allowance for loan losses was $31.0 billion, or 7.01%, of total Consumer loans, at quarter-end, compared to $39.6 billion, or 7.87%, at June 30, 2010.

Citigroup's non-accrual loans of $13.2 billion declined 47% from the prior-year period. At the end of the second quarter of 2011, the allowance for loan losses was 260% of non-accrual loans.

Citicorp

Citicorp net income of $3.7 billion in the second quarter of 2011 declined 2% from the prior-year period. Year-over-year, revenues declined less than 1%, and lower net credit losses and a higher net loan loss reserve release more than offset an increase in operating expenses. Citicorp's international operations accounted for over 68% of second quarter 2011 net income from continuing operations.

Citicorp revenues were $16.3 billion, down $141 million from the second quarter of 2010, driven by a positive credit valuation adjustment (CVA) of $147 million in the second quarter of 2011, compared to a positive CVA of $255 million in the prior-year period. Excluding CVA, Citicorp revenues were flat year-over-year, as growth in international Regional Consumer Banking and Transaction Services was offset by lower revenues in North America Regional Consumer Banking and Securities and Banking . Sequentially, Citicorp revenues, excluding CVA, were down 3% as growth in Regional Consumer Banking and Transaction Services was more than offset by lower revenues in Securities and Banking . Net interest revenues of $9.5 billion declined 1% from the prior-year period, and non-interest revenues were flat versus the prior year at $6.8 billion.

Regional Consumer Banking revenues of $8.2 billion were 2% higher year-over-year, mostly due to continued growth in business volumes across international regions as well as the impact of FX translation. This growth was partly offset by lower credit card balances in North America, the impact of The Credit Card Accountability Responsibility and Disclosure Act (CARD Act), and continued spread compression in Asia and Latin America. Average retail banking loans increased 18% year-over-year to $129.0 billion, and average deposits increased 8% to $314.5 billion, both driven by Asia and Latin America. Citi-branded cards average loans increased 1% year-over-year to $110.1 billion, as growth in Asia and Latin America was offset by lower balances in North America. Cards purchase sales grew 12% from the prior-year period to $71.3 billion, and international investment sales increased 5% to $24.5 billion.

Securities and Banking revenues of $5.5 billion declined 8% year-over-year, driven principally by lower revenues in fixed income markets. Sequentially, revenues declined 9%, driven by lower revenues in fixed income and equity markets, partially offset by a strong quarter in investment banking. Excluding CVA, revenues of $5.3 billion were down 7% from the prior-year period and down 15% sequentially. Fixed income markets revenues of $2.9 billion, excluding CVA, decreased 16% year-over-year, largely due to lower revenues in G10 rates and currencies, partially offset by growth in emerging markets, and 27% sequentially, driven by credit-related and securitized products. Equity markets revenues of $776 million, excluding CVA, were 25% higher year-over-year, mainly driven by derivatives, but down 30% sequentially, mainly due to lower market volumes and a challenging trading environment as compared to the first quarter of 2011, particularly in derivatives. Investment banking revenues were $1.1 billion, up 61% from the prior-year period and 27% sequentially, reflecting increased activity in both advisory and underwriting activities.

Transaction Services revenues were $2.7 billion, up 6% from the prior-year period, driven by growth in Treasury and Trade Solutions as well as Securities and Fund Services. Revenues grew year-over-year in all international regions, as strong growth in business volumes was partially offset by continued spread compression. Average deposits and other customer liabilities grew 14% year-over-year to $365 billion, while assets under custody grew 19% to $13.5 trillion.

Citicorp end of period loans increased 16% year-over-year to $440 billion, with 11% growth in Consumer loans and 22% growth in Corporate loans.

Citi Holdings

Citi Holdings net loss of $218 million in the second quarter of 2011 was 82% less than the net loss of $1.2 billion in the second quarter of 2010, as lower operating expenses, a continued improvement in net credit losses and a higher net loan loss reserve release offset lower revenues.

Citi Holdings revenues declined 18% to $4.0 billion from the prior-year period. Net interest revenues declined 33% year-over-year to $2.7 billion, largely driven by declining loan balances in Local Consumer Lending and lower interest-earning assets in the Special Asset Pool . Non-interest revenues increased 43% to $1.4 billion from the prior-year period, mostly reflecting the $511 million of pre-tax gains realized in the second quarter of 2011 on the sale of assets transferred out of held-to-maturity in the first quarter of 2011.

Citi Holdings assets declined 34% from the second quarter of 2010 to $308 billion at the end of the second quarter of 2011. The decline reflected $108 billion in asset sales and business dispositions (including the sale of the previously-disclosed $12.7 billion of assets transferred out of held-to-maturity in the Special Asset Pool in the first quarter of 2011), $42 billion in net run-off and amortization, and $7 billion in net cost of credit and net asset marks. Local Consumer Lending continues to represent the largest segment within Citi Holdings, with $228 billion of assets at the end of the second quarter of 2011. Over half of Local Consumer Lending assets, or approximately $119 billion, were related to North America real estate lending. As of the end of the second quarter of 2011, there were approximately $10 billion of loan loss reserves allocated to North America real estate lending in Citi Holdings, representing over 27 months of coincident net credit loss coverage. At the end of the second quarter of 2011, Citi Holdings assets comprised approximately 16% of total Citigroup GAAP assets and 28% of risk-weighted assets.
