Management Comment

        "In the second quarter, we achieved our second highest income from continuing operations while making significant progress on our strategic initiatives. We added a record number of new consumer branches during the quarter, bringing our total year-to-date new branch openings to 508. We also opened corporate and investment banking offices in Kuwait and Dubai. The results from our newly launched Citibank e-savings business have been exceptional, with $4.2 billion of deposits since its launch 3 months ago—approximately two-thirds representing new money to Citibank," said Charles Prince, Chairman and Chief Executive Officer of Citigroup.

        "In international consumer, strong volume growth across our franchise drove a 12% increase in revenues. U.S. consumer also achieved strong volume growth and, despite headwinds from spread compression, showed improving momentum from the first quarter. And in corporate and investment banking, we achieved our second highest revenues, despite challenging conditions in the emerging markets," said Prince.

        "We are very pleased with the momentum we are building as we execute on our strategic initiatives, strengthen our franchises, and position Citigroup for continued long-term earnings growth," said Prince.

•

U.S. Cards

—

Net income increased 19%. Lower bankruptcy filings and a continued favorable credit environment led to a $193 million decline in net credit losses and a $160 million pre-tax loan loss reserve release. The managed net credit loss ratio declined 169 basis points to 4.11%.



—

Revenues were approximately even with the prior-year period, as 2% growth in average managed loans and a 12% increase in purchase sales were offset by higher payment rates and net interest margin compression.



—

Growth in average managed loans reflected a shift from traditional card products to higher reward and private label card balances, including the addition of Federated card receivables.



•

U.S. Retail Distribution

—

Revenue growth was driven by a $132 million pre-tax gain on the sale of retail bank branches in upstate New York and increased customer business volumes, which were partially offset by net interest margin compression. Deposits and loans grew 8% and 10%, respectively, and investment product sales increased 37%.



—

Expenses increased 8%, reflecting higher business volumes and investment in new branches. During the quarter, 74 new branches were opened and the Citibank e-savings business achieved deposit balances of $4.2 billion.



—

Credit costs declined due to lower bankruptcy filings and a continued favorable credit environment. The NCL rate declined 85 basis points to 2.65%.



•

U.S. Consumer Lending

—

Revenues declined, as 21% growth in average loans was offset by net interest margin compression across the loan portfolios. The revenue decrease also reflected a decline in net mortgage servicing revenues, which was partially offset by higher gains on loan sales.



—

Expenses increased 8% due to increased business volumes. Lower credit costs reflected a $75 million pre-tax loan loss reserve release.



•

U.S. Commercial Business

—

Revenue growth was driven by a $31 million pre-tax gain on the sale of branches in upstate New York and increased deposit and loan balances, each up 11%, which were offset by net interest margin compression.



—

Credit costs remained low, reflecting the continued favorable credit environment.

3

•

International Cards

—

Revenue growth of 28% was driven by higher purchase sales and average loans, up 15% and 18% respectively, improved net interest margins, and the integration of Credicard in Brazil. Loan growth was led by Mexico, Asia, and Latin America.



—

Expense growth of 24% reflected the integration of Credicard, continued investment in organic growth, and higher customer activity.



—

Net income declined due to higher credit costs, which were primarily driven by industry-wide credit deterioration in the Taiwan cards market. Net income increased significantly in Mexico, EMEA and Latin America.



•

International Consumer Finance

—

In Japan, revenues and net income declined 3% and 2%, respectively, as a decline in average loans was partially offset by lower expenses and lower credit costs. Average loans increased 3% from the first quarter 2006, driven by a strong increase in new loan originations. During the quarter, 85 new automated loan machines (ALMs) were added.



—

Outside of Japan, revenues increased 20%, driven by 17% growth in average loans. Net income declined 3% as revenue growth was offset by increased investment spending. During the quarter, 111 new branches were opened.



•

International Retail Banking

—

Revenue and net income growth reflected a 9% increase in deposits and 60% growth in investment product sales. Loan balances increased 1%, as declines in EMEA and Asia—which were driven by the third quarter 2005 write-off of loans in Germany and the recent labor actions in Korea, respectively—were offset by growth in all other regions.



—

Expense growth reflected increased business volumes and continued investment spending, with 85 new branch openings during the quarter.



—

Credit costs improved due to the favorable credit environment and a loan loss reserve release of $82 million pre-tax in Korea.
