(&amp;#8220;Siperian&amp;#8221;), a privately-held company. Siperian provides&lt;/font&gt;&lt;font style="font-family:Arial;font-size:9pt;font-weight:bold;"&gt; &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;an integrated model-driven master data management (&amp;#8220;MDM&amp;#8221;) platform that adapts to most business requirements.

As a result of this acquisition, the Company also assumed certain facility leases and certain liabilities and commitments. Approximately $18.3 million of the consideration otherwise payable to former Siperian stockholders, vested option holders, and participants in Siperian's Management Acquisition Bonus Plan was placed into an escrow fund and held as partial security for the indemnification obligations of the former Siperian stockholders, vested option holders, and participants in Siperian's Management Acquisition Bonus Plan set forth in the merger agreement and for purposes of the working capital adjustment stated in the contract. The escrow fund will remain in place until July 28, 2011, although a portion of the escrow funds were paid out in February 2011.&lt;/font&gt;&lt;/div&gt;&lt;div

style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;On March 22, 2010, the Company acquired 29West Inc. (&amp;#8220;29West&amp;#8221;), a privately-held company. 29West develops high-speed messaging software, known as Ultra Messaging. This software is used for distribution of data, streaming market data, and proprietary trading and market making, and is sold to banks, hedge funds, exchanges, and software application vendors worldwide. The Company acquired 29West in a stock purchase transaction valued at approximately &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$50.0 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;. As a result of this acquisition, the Company also assumed certain facility leases, liabilities, and commitments. Approximately $7 million of the consideration otherwise payable to former 29West stockholders and vested option holders was placed into an escrow fund and held as partial security for the indemnification obligations of the former 29West stockholders and vested option holders. The escrow fund will remain in place until September 22, 2011. &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&amp;nbsp;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The following table presents the purchase price allocation of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$47.0 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and the acquiree's transaction related costs of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$3.0 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;.

Agent Logic, Inc. (&amp;#8220;Agent Logic&amp;#8221;), a privately held company. Agent Logic specializes in the development and marketing of complex event processing software which supports security initiatives in highly complex environments. Informatica acquired all of the capital stock of Agent Logic in a cash merger transaction for $35 million, of which $6.1 million is held in an escrow fund as security for losses accrued by Informatica in the event of certain breaches of the merger agreement by Agent Logic. The escrow fund will remain in place for a period of eighteen months from the date of acquisition, although&amp;#160;a portion of the escrow funds were paid out in September 2010.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Informatica is obligated to pay certain variable and deferred earn-out payments if certain license order targets are achieved. The Company determined the fair market value of these earn-outs based on probability analysis. The fair market value and gross amount of these earn-outs at the time of acquisition were $2.6 million and $3.1 million, respectively. Changes in this estimate are recorded in the statement of income. &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Informatica is obligated to pay certain employees of Agent Logic retention bonuses of approximately $0.8 million if they continue to provide their employment services for a certain period of time. These expenses are recorded as the services are performed between 12 to 24 months subsequent to the acquisition date.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The excess of the purchase price over the identified tangible and intangible assets was recorded as goodwill. Using the information available at the time of the acquisition, the Company allocated approximately $13.0 million of the purchase price to identified intangible assets and $1.8 million of the purchase price to net tangible assets. Identified intangible assets included developed and core technology, customer relationships, and trade names. The Company recorded the excess purchase price of $24.4 million as goodwill, which is not deductible for tax purposes. The trade names and developed and core technology are being amortized over five years, and customer relationships are being amortized over six years.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;text-decoration:underline;"&gt;AddressDoctor GmbH&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;On June 2, 2009, Informatica GmbH, a wholly owned subsidiary of Informatica, acquired AddressDoctor GmbH (&amp;#8220;AddressDoctor"), a limited liability company. AddressDoctor is a leading provider of international address verification and cleaning solutions that enables users to validate and correct postal addresses and assists in the data capturing process. Informatica acquired all of the capital stock of AddressDoctor for approximately $27.8 million.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The excess of the purchase price over the identified tangible and intangible assets was recorded as goodwill. Using the information available at the time of the acquisition, the Company allocated approximately $9.7 million of the purchase price to net intangible assets and $5.0 million to net assumed liabilities. Identified intangible assets included developed and core technology, vendor relationships, customer relationships, and trade names. The Company recorded the excess purchase price of $23.0 million as goodwill, of which $6.8 million will be deductible for tax purposes due to the sale of intellectual property rights to the U.S. entity. The trade names and the developed and core technology are being amortized over five years, vendor relationships are being amortized over five years, and customer relationships are being amortized over six years.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;text-decoration:underline;"&gt;Applimation&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;On February 13, 2009, the Company acquired Applimation, Inc. (&amp;#8220;Applimation&amp;#8221;), a privately held company, providing application Information Lifecycle Management (ILM) technology.

The Company acquired all of the capital stock of Applimation in a cash merger transaction valued at approximately $37.2 million, including in $1.6 million retention bonuses payable three to eighteen months subsequent to acquisition date. As a result of this acquisition, the Company also assumed certain facility leases and certain liabilities and commitments. &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Informatica is obligated to reimburse certain employees of Applimation for an approximate bonus of $1.6 million if they continue to provide their employment services for a certain period of time. If they discontinue their services for any reason, these amounts are payable to original shareholders of Applimation. These expenses are recorded as the services are performed between three to 18 months subsequent to the acquisition date.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The Company determined, based on probability analysis, that the amount of bad debt reserve for the accounts receivable acquired through acquisition was $0.4 million. In the fourth quarter of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;2010&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, Informatica increased this estimate by an additional $0.4 million, due to additional probability analysis. Informatica reflected the excess of this estimate of $0.4 million in its statement of income in the fourth quarter of 2009 based on ASC 805.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-top:12px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The excess of the purchase price over the identified tangible and intangible assets was recorded as goodwill.

Identified intangible assets included developed and core technology, customer relationships, and trade names. The Company recorded the excess purchase price of $19.7 million as goodwill, which is not deductible for tax purposes. The trade names and developed and core technology are being amortized over five years, and customer relationships are being amortized over six years.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:24px;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&amp;nbsp;&lt;/font&gt;&lt;/div&gt;&lt;/div&gt;</NonNumbericText><NonNumericTextHeader>AcquisitionsAcquisitions in 2010Siperian, Inc.&amp;nbsp;On January 28, 2010, the Company acquired Siperian, Inc.
