Adjusted EBITDA increased 5.3% to a record $54.0 million in third quarter 2009 for an adjusted EBITDA margin of a record 49.6% and increased 6.5% to $155.8 million for an adjusted EBITDA margin of 48.1% for the nine months ended August 31, 2009. See Tables 9 and 13 each titled "Reconciliation of Adjusted EBITDA to Net Income."

Henry A. Fernandez, Chairman and CEO, said “I am pleased to report record levels of profitability with third quarter adjusted EBITDA of $54.0 million and a margin of 49.6%. The high margin inherent across most of our products coupled with our disciplined expense management enabled us to grow adjusted EBITDA 5.3% from a year-ago despite a 1.4% decline in revenues to $108.9 million. Excluding a one-time foreign exchange adjustment of $3.3 million, revenues increased 1.6% to $112.2 million. Our fees from licensing exchange traded funds experienced strong growth as the recovery in financial markets around the world continued during the quarter while our subscription fees were impacted by the lagging nature of our business relative to the market environment.”

“Early in the fourth quarter, we are seeing signs of easing budget constraints among some of our subscription fee clients which is resulting in healthy levels of sales activity. Retention rates, however, will likely remain under pressure as the operating environment for us remains challenging and many clients continue to monitor their spending closely. Notwithstanding the short-term challenges, our growth opportunities remain significant, and we continue to grow our headcount to capitalize on these opportunities and deliver value for our clients and shareholders,” added Mr. Fernandez.

Total operating revenues for the three months ended August 31, 2009 (third quarter 2009) decreased $1.5 million, or 1.4%, to $108.9 million compared to $110.4 million for the three months ended August 31, 2008 (third quarter 2008). The decrease was comprised of a 3.6% decrease in subscription revenues to $88.7 million offset, in part, by a 10.0% increase to $20.1 million in equity index asset based fees. The decrease in subscription revenues was driven by declines in revenues related to Equity Portfolio Analytics, Multi-Asset Class Portfolio Analytics and Other Products which were down 13.4%, 12.4% and 25.2%, respectively, in third quarter 2009 offset, in part, by an increase of 8.5% in equity index subscriptions. Within our subscription product categories, declines occurred in the Americas and EMEA while there was growth in Asia Pacific and Japan. By client segment, revenues declined from asset managers, broker dealers and hedge funds while revenues increased from asset owners and the others category which includes vendors, custodians and private banks. Our revenues, excluding asset based fees, for third quarter 2009 would have been higher by $0.3 million had the U.S. dollar not strengthened relative to the prior year using foreign exchange rates for the same period of the prior year.

In third quarter 2009, MSCI adjusted certain foreign exchange rates used to amortize its deferred revenue. As a result of this one-time adjustment, MSCI recorded a $3.3 million aggregate reduction to revenues in third quarter 2009 to correct for revenues previously reported through May 31, 2009. By product category, the adjustment increased Equity Indices by $0.7 million and decreased Equity Portfolio Analytics, Multi-Asset Class Portfolio Analytics and Other Products by $1.4 million, $2.3 million and $0.3 million, respectively. Excluding this one-time foreign exchange adjustment, revenues increased $1.8 million, or 1.6%, to $112.2 million compared to the same period in 2008.

Revenues from equity index subscriptions were up 8.5% to $47.4 million in third quarter 2009 with growth across all regions and client categories with the exception of hedge funds. This growth was led by strong increases in our emerging market, small cap and developed market subscription index modules as well as in user fees and reporting license fees, which more than offset a significant decline in non-subscription fees for historical index data.

Revenues attributable to equity index asset based fees increased 10.0% to $20.1 million in third quarter 2009 compared to third quarter 2008 reflecting increases of 7.8% to $15.4 million for ETF asset based fees, 23.0% to $3.7 million for institutional and retail indexed funds asset based fees and 1.4% to $1.0 million for other asset and transaction based fees. The average value of assets in ETFs linked to MSCI equity indices increased 1.1% to $180.3 billion for third quarter 2009 compared to $178.3 billion for third quarter 2008. As of August 31, 2009, the value of assets in ETFs linked to MSCI equity indices was $199.2 billion, representing an increase of $32.9 billion, or 19.8%,

Compared to second quarter 2009, equity index asset based fee revenues increased 32.3%, led by growth in ETF asset based fees. The average value of assets in ETFs linked to MSCI equity indices increased 33.8% to $180.3 billion from $134.7 billion in second quarter 2009. The increase in the value of assets in ETFs linked to MSCI equity indices at the end of third quarter 2009 compared to second quarter 2009 was 13.3%, or $23.3 billion. We estimate that the $23.3 billion increase from second quarter 2009 was attributable to asset appreciation of $20.1 billion and asset inflows of $3.2 billion. The $3.2 billion of asset inflows was comprised of $1.9 billion of asset inflows into established ETFs supplemented by $1.3 billion of asset inflows into ETFs launched over the last 12 months.

Equity Portfolio Analytics: Revenues related to Equity Portfolio Analytics products decreased $4.5 million, or 13.4%, to $29.2 million in third quarter 2009 compared to the same period in 2008 resulting from lower levels of new subscriptions, lower retention rates in recent quarters (most notably for Aegis, our proprietary equity risk data and software product) and the aforementioned revenue adjustment. Revenues were lower in all regions, most notably EMEA, and all client categories with the exception of the asset owners category. Revenues declined 14.6% to $19.5 million for Aegis, 9.6% to $8.5 million for Models Direct (our proprietary risk data product accessed directly) and 19.4% to $1.1 million for Barra on Vendors (our proprietary risk data product accessed through third party vendors).

Multi-Asset Class Portfolio Analytics: Revenues related to Multi-Asset Class Portfolio Analytics decreased $1.1 million, or 12.4%, to $7.8 million in third quarter 2009 compared to the same period in 2008. This decrease is comprised of a 5.5% decline to $6.2 million for BarraOne and a 32.0% decline to $1.6 million for TotalRisk, which is in the process of being decommissioned with its existing users being offered the opportunity to transition to BarraOne. The decrease reflects the aforementioned revenue adjustment. From a regional perspective, declines were reported in the Americas and EMEA while growth was experienced in both Asia Pacific and Japan. Within client categories, declines were experienced in the asset managers, hedge funds and others segments while growth was reported in the broker dealers and asset owners segments.

Other Products: Revenues from Other Products decreased $1.5 million, or 25.2%, to $4.4 million in third quarter 2009 compared to the same period in 2008. The decrease reflects declines of 10.5% to $3.1 million for our energy and commodity analytics products and 24.3% to $1.3 million for fixed income analytics. The decline in our energy and commodity analytics products largely reflects the absence of non-recurring revenue recorded in third quarter 2008 which did not repeat in third quarter 2009. Revenue for investable hedge fund indices in third quarter 2009 was negligible compared to the $0.7 million in third quarter 2008. The decline largely reflects the termination of the last remaining MSCI investable hedge fund indices license.

Operating expenses decreased $1.8 million, or 2.5%, to $71.1 million in third quarter 2009 compared to third quarter 2008 largely reflecting the elimination of the expense allocation from Morgan Stanley and reductions in professional services expenses and amortization of intangibles, partially offset by increases in compensation, information technology and depreciation expenses. Our operating expense for third quarter 2009 would have been higher by $3.0 million had the U.S. dollar not strengthened relative to the prior year using foreign exchange rates for the same period in 2008.

Compensation expense increased $1.4 million, or 3.2%, to $43.8 million in third quarter 2009 (including higher founders grant expense of $1.5 million). Excluding founders grant expenses, compensation expense decreased 0.4% to $37.0 million. The decrease excluding founders grant expense reflects favorable foreign exchange rates (principally the strengthening of the US dollar) which lowered reported compensation expense for staff located outside the United States and a lower bonus accrual in third quarter 2009 offset, in part, by compensation cost for new hires, a $0.9

million increase in severance and $0.8 million of stock based compensation costs relating to the restricted stock units granted as a component of the 2008 annual bonus. The number of full-time employees increased by 126 to 850 on August 31, 2009 from 724 on August 31, 2008 and by 45 from 805 on May 31, 2009. In third quarter 2009, we continued to increase our staff in emerging market centers. As of August 31, 2009, 39% of our employees were located in emerging market centers compared to 26% as of August 31, 2008.

Non-compensation expenses excluding depreciation and amortization of intangibles decreased $4.1 million to $17.9 million, an 18.6% decrease, reflecting the elimination of the expense allocation from Morgan Stanley and lower professional services expenses offset, in part, by increases in expenses related to information technology infrastructure.

Cost of services expenses increased $0.5 million, or 1.6%, to $28.2 million in third quarter 2009. Compensation expenses increased 6.3% to $21.0 million reflecting higher founders grant expense of $0.7 million and higher headcount which were offset, in part, by favorable foreign exchange rates which lowered reported compensation expense for staff outside the United States. Non-compensation expenses decreased 10.0% to $7.2 million largely reflecting the elimination of the expense allocation from Morgan Stanley.

Selling, general and administrative expenses decreased $3.2 million, or 8.6%, to $33.5 million in third quarter 2009. Compensation expenses increased 0.6% to $22.8 million, reflecting higher founders grant expense of $0.8 million and higher headcount offset, in part, by favorable foreign exchange rates, which lowered reported compensation expense for staff outside the United States, and a lower bonus accrual. Non-compensation expenses decreased 23.5% to $10.7 million reflecting the elimination of the expense allocation from Morgan Stanley as well as lower professional services and travel and entertainment expenses. Selling expenses decreased 7.0% to $10.4 million in third quarter 2009 and general and administrative expenses decreased 9.3% to $23.1 million.

Founders grant expenses increased to $6.9 million in third quarter 2009 compared to $5.3 million in third quarter 2008, reflecting less attrition of employees with founders grant awards. Expenses related to the founders grant awards reflect the amortization of share based compensation expenses associated with restricted stock units and options awarded to employees as a one-time grant in connection with our IPO completed in November 2007. Of the $6.9 million of founders grant expenses in third quarter 2009, $2.3 million was recorded in cost of services and $4.6 million was recorded in selling, general and administrative expenses.

Other expense (income), net was an expense of $4.1 million in third quarter 2009 compared to an expense of $7.4 million in third quarter 2008. The $3.3 million decrease primarily reflects a gain of $0.2 million related to changes in foreign exchange rates in third quarter 2009 compared to a loss of $3.0 million a year ago and a reduction of $1.4 million in interest expense due to lower average outstanding debt and the impact of lower interest rates on the unhedged portion of our debt, partially offset by a decrease of $1.5 million in interest income resulting from lower interest returns on invested balances.

The provision for income taxes increased 13.5% to $12.8 million in third quarter 2009. The effective tax rate for third quarter 2009 was 37.9% compared to 37.4% in third quarter 2008. The $1.5 million increase in the income tax expense was primarily the result of higher pre-tax earnings during the current year.

Adjusted EBITDA increased 5.3% to $54.0 million for third quarter 2009 from $51.3 million for third quarter 2008. See Table 9 titled “Reconciliation of Adjusted EBITDA to Net Income” and “Notes Regarding the Use of Non-GAAP Financial Measures” below. The adjusted EBITDA margin increased to 49.6% in third quarter 2009 from 46.4% in third quarter 2008.

Our Aggregate Retention Rate (as defined in Table 3) declined to 80.6% for third quarter 2009 from 91.6% for third quarter 2008, reflecting year-over-year declines in each of the four product categories. Our Core Retention Rate (as defined in Table 3) was 81.9% for third quarter 2009 compared to 94.1% for third quarter 2008. See Table 3 for Retention Rates by product category.

Total operating revenues for the nine month period ended August 31, 2009 (first nine months 2009) increased $0.6 million, or 0.2%, to $324.2 million compared to the nine month period ended August 31, 2008 (first nine months 2008). Revenue gains were reported in two of our four product categories. Our revenues, excluding asset based fees, for the first nine months 2009 would have been higher by $2.6 million had the US dollar not strengthened relative to the prior year using foreign exchange rates for the same period of the prior year.

For the first nine months 2009, the aforementioned one-time foreign exchange adjustment resulted in an aggregate reduction of $2.2 million to correct for revenues previously reported through November 30, 2008. By product category, the adjustment increased Equity Indices by $0.5 million and decreased Equity Portfolio Analytics, Multi-Asset Class Portfolio Analytics and Other Products by $0.9 million, $1.6 million and $0.2 million, respectively.

Revenues from our subscription products grew $8.3 million, or 3.1%, in aggregate for the first nine months 2009 to $275.6 million. Revenues attributable to equity index asset based fees decreased $7.7 million, or 13.6%, to $48.6 million in the first nine months 2009. Within our subscription product categories, revenue growth was experienced across all regions, with the exception of EMEA, and all client segments with the exception of hedge funds. Total revenue growth was led by equity index subscriptions, which increased 12.6% to $139.9 million for the first nine months 2009 compared to the first nine months 2008 and by Multi-Asset Class Portfolio Analytics which increased 6.3% to $27.0 million and was primarily driven by new subscriptions to BarraOne.

Revenues from Equity Portfolio Analytics decreased 7.0% to $92.9 million for the first nine months 2009 reflecting lower levels of new subscriptions and lower retention rates. Other Products decreased 11.0% to $15.8 million for the first nine months 2009 compared to the same period in 2008. The decline reflects a decrease of 72.7% in asset based fees from investment products linked to MSCI investable hedge fund indices products and a decrease of 11.1% for fixed income analytics offset by a 4.3% increase for our energy and commodity analytics products.

Operating expenses for the first nine months 2009 decreased $1.0 million, or 0.5%, to $216.9 million compared to the first nine months 2008 largely reflecting the reduction of the expense allocation from Morgan Stanley and reductions in professional services expenses, travel and entertainment expenses, and amortization of intangibles. These reductions were partially offset by increases in compensation, information technology and depreciation expenses.

Compensation expense increased $7.4 million, or 5.8%, to $134.9 million for the first nine months 2009. Excluding founders grant expenses, compensation expense increased 3.6% to $114.5 million. The increase in compensation expense includes costs for new hires, $2.2 million of stock based compensation costs relating to the restricted stock units granted as a component of the 2008 annual bonus and $1.1 million of severance. These increases were offset, in part, by favorable foreign exchange rates (principally the strengthening of the US dollar) which lowered reported compensation expense for staff located outside the United States, increased migration to emerging market centers and a lower bonus accrual in the first nine months 2009. Non-compensation expense decreased $13.0 million, or 19.4%, to $53.8 million largely reflecting a reduction in the expense allocation from Morgan Stanley offset, in part, by an increase in expenses related to replacing services previously provided by Morgan Stanley.

Selling, general and administrative expenses decreased $3.7 million, or 3.5%, to $102.3 million in the first nine months 2009. The decline resulted from a reduction in costs allocated by Morgan Stanley, partially offset by an increase in expenses related to replacing services previously provided by Morgan Stanley, principally compensation, information technology and insurance.

Other expense (income), net was an expense of $15.2 million for the first nine months 2009 compared to an expense of $16.3 million for the first nine months 2008. The $1.1 million decrease primarily reflects a reduction of $6.0 million in interest expense due to lower average outstanding debt and the impact of lower interest rates on the unhedged portion of our debt and a loss of $0.4 million related to changes in foreign exchange rates in the current year compared to a loss of $3.0 million in the prior year, partially offset by a decrease of $7.0 million in interest income resulting from lower interest returns on invested balances.

The provision for income taxes increased 2.9% to $34.8 million for the first nine months 2009 compared to the first nine months 2008. The effective tax rate for the first nine months 2009 was 37.8% compared to 37.9% for the first nine months 2008. The $1.0 million increase in the income tax expense was primarily the result of higher pre-tax earnings during the current year.

Net income increased 3.3% to $57.3 million for the first nine months 2009 from the first nine months 2008 and the net income margin was 17.7%. The increase in net income primarily reflects higher revenues, lower operating expenses, lower interest expense and higher interest income.

Adjusted EBITDA increased 6.5% to $155.8 million for the first nine months 2009 from $146.3 million for the comparable period in 2008. See Table 13 titled “Reconciliation of Adjusted EBITDA to Net Income.” The adjusted EBITDA margin increased to 48.1% for the first nine months 2009 from 45.2% for the first nine months 2008.

1 The run rate at a particular point in time represents the forward-looking fees for the next 12 months from all subscriptions and investment product licenses we currently provide to our clients under renewable contracts assuming all contracts that come up for renewal are renewed and assuming then-current exchange rates. For any license whose fees are linked to an investment product’s assets or trading volume, the run rate calculation reflects an annualization of the most recent periodic fee earned under such license. The run rate does not include fees associated with “one-time” and other non-recurring transactions. In addition, we remove from the run rate the fees associated with any subscription or investment product license agreement with respect to which we have received a notice of termination or non-renewal at the time we determine that such notice evidences the client's final decision to terminate or not renew the applicable subscription or agreement, even though the notice is not effective until a later date.

1 The quarterly Aggregate Retention Rates are calculated by annualizing the cancellations for which we have received a notice of termination or non-renewal during the quarter and we have determined that such notice evidences the client’s final decision to terminate or not renew the applicable subscription or agreement, even though such notice is not effective until a later date. This annualized cancellation figure is then divided by the subscription Run Rate at the beginning of the year to calculate a cancellation rate. This cancellation rate is then subtracted from 100% to derive the annualized Retention Rate for the quarter. The Aggregate Retention Rate is computed on a product-by-product basis. Therefore, if a client reduces the number of products to which it subscribes or switches between our products, we treat it as a cancellation. In addition, we treat any reduction in fees resulting from renegotiated contracts as a cancellation in the calculation to the extent of the reduction. Aggregate Retention Rates are generally higher during the first three fiscal quarters and lower in the fourth fiscal quarter. For the calculation of the Core Retention Rate the same methodology is used except the amount of cancellations in the quarter is reduced by the amount of product swaps.

1 All stock based compensation other than the founders grant is considered an expense for purposes of calculating adjusted EBITDA

Adjusted EBITDA is defined as income before interest income, interest expense, other income, provision for income taxes, depreciation, amortization and founders grant expense. Adjusted EBITDA is not presented as an alternative measure of operating results, as determined in accordance with accounting principles generally accepted in the U.S. Rather, we believe adjusted EBITDA is one additional measure that investors use to evaluate companies, like our company, that have substantial amortization of intangible assets and other unusual one-time non-cash charges included in their statement of income. This is particularly relevant to a company in our industry because we do not believe other companies in our industry have as significant a proportion of their operating expenses represented by amortization of intangible assets and one-time founders grant as we do. As stated above, adjusted EBITDA excludes expense for the one-time $68.0 million founders grant which is being amortized through 2011. Management believes that it is useful to exclude the founders grant expense in order to focus on what is deemed to be a more reliable indicator of ongoing operating performance. Amortization expense for the one-time $68.0 million founders grant, representing restricted stock units and options awarded to employees effective with the IPO, is expected to be amortized through 2011.

Additionally, our management uses adjusted EBITDA to compare MSCI to other companies in the same industry when evaluating relative performance and industry development. Adjusted EBITDA as presented herein, however, may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA is a non-GAAP measure that should not be considered as an alternative to net income, as an indication of financial performance or as an alternative to cash flow from operations as a measure of liquidity.

Operating expenses excluding founders grant (described above), cost of services expenses excluding founders grant, and selling, general, and administrative expenses excluding founders grant are deemed to be a more reliable indicator of ongoing expense trends. Management believes that it is useful to exclude founders grant expenses from operating expenses because the founders grant was a one-time event, although the amortization expense of the award will be recognized over four years.
