	1.       ACCOUNTING POLICIES
	Basis of Presentation
	Pegasystems Inc. (together with its subsidiaries, “the Company”) has prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“U.S.”) for complete financial statements and should be read in conjunction with the Company’s audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2012.
	In the opinion of management, the Company has prepared the accompanying unaudited condensed consolidated financial statements on the same basis as its audited financial statements, and these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of the interim periods presented. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full year 2013.
	Acquisition-related costs
	Acquisition-related costs are expensed as incurred and include costs to affect an impending or completed acquisition and direct and incremental costs associated with an acquisition. During the third quarter of 2013, acquisition-related costs of $0.5 million were primarily legal and advisory fees and due diligence costs associated with the Company’s acquisition of Antenna Software, Inc. (“Antenna”). See Note 12 “Subsequent Event”.

Derivative Instruments	'
	3.  DERIVATIVE INSTRUMENTS
	The Company uses foreign currency forward contracts (“forward contracts”) to manage its exposure to changes in foreign currency denominated accounts receivable, intercompany payables and cash primarily held by the U.S. operating company. The Company has been primarily exposed to the fluctuation in the British pound and Euro relative to the U.S. dollar. More recently, the Company has experienced increased levels of exposure to the Australian dollar and Indian rupee, for which it began to use forward contracts in the third quarter of 2013.
	The forward contracts utilized by the Company are not designated as hedging instruments and as a result, the Company records the fair value of these contracts at the end of each reporting period in its consolidated balance sheet as other current assets for unrealized gains and accrued expenses for unrealized losses, with any fluctuations in the value of these contracts recognized in other expense, net, in its consolidated statement of operations. These forward contracts have 90 day terms or less.
	As of September 30, 2013 and December 31, 2012, the Company did not have any forward contracts outstanding.
	During the third quarter and first nine months of 2013 and 2012, the Company entered into forward contracts with notional values as follows:
		Notional Amount

Fair Value Measurements	'
	4.  FAIR VALUE MEASUREMENTS
	Assets Measured at Fair Value on a Recurring Basis
	Fair value is an exit price, representing the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants based on assumptions that market participants would use in pricing an asset or liability. As a basis for classifying the fair value measurements, a three-tier fair value hierarchy, which classifies the fair value measurements based on the inputs used in measuring fair value, was established as follows: (Level 1) observable inputs such as quoted prices in active markets for identical assets or liabilities; (Level 2) significant other observable inputs that are observable either directly or indirectly; and (Level 3) significant unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company records its marketable securities at fair value.
	The Company’s investments are classified within Level 1 and Level 2 of the fair value hierarchy. The Company’s investments classified within Level 1 of the fair value hierarchy are valued using quoted market prices. The Company’s investments classified within Level 2 of the fair value hierarchy are valued based on matrix pricing compiled by third party pricing vendors, using observable market inputs such as interest rates, yield curves, and credit risk.
	The fair value hierarchy of the Company’s cash equivalents and marketable securities at fair value is as follows:

	Assets recorded at fair value on a nonrecurring basis, such as property and equipment, and intangible assets, are recognized at fair value when they are impaired. During the first nine months of 2013 and 2012, the Company did not recognize any impairments on its assets measured at fair value on a nonrecurring basis.

	During the first nine months of 2013, the Company granted approximately 114,000 restricted stock units (“RSUs”) with a total fair value of approximately $3.3 million. Approximately 59,000 RSUs were issued in connection with the election by employees to receive 50% of their 2013 target incentive compensation under the Company’s Corporate Incentive Compensation Plan (the “CICP”) in the form of RSUs instead of cash. Stock-based compensation of approximately $1.7 million associated with this RSU grant will be recognized over a one-year period beginning on the grant date.
	As of September 30, 2013, the Company had approximately $12.2 million of unrecognized stock-based compensation expense, net of estimated forfeitures, related to all unvested RSUs and unvested stock options that is expected to be recognized over a weighted-average period of 2.1 years.

Earnings Per Share	'

	Basic earnings per share is computed using the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per share is computed using the weighted-average number of common shares outstanding during the applicable period, plus the dilutive effect of outstanding options, RSUs, and warrants, using the treasury stock method and the average market price of the Company’s common stock during the applicable period. Certain shares related to some of the Company’s outstanding stock options and RSUs were excluded from the computation of diluted earnings per share because they were antidilutive in the periods presented, but could be dilutive in the future.

To assess performance, the Company’s chief operating decision maker primarily reviews financial information on a consolidated basis. Therefore, the Company has determined it operates in one segment — Business Process Solutions.

Subsequent Event	'
	12.   SUBSEQUENT EVENT
	On October 9, 2013, the Company acquired Antenna, a leading provider of mobile application development platforms. The Company acquired all of the outstanding capital stock of Antenna in a merger for $26.3 million in cash. The Company is in the process of preparing an allocation of the purchase price to the fair value of assets acquired and liabilities assumed, but currently expects that a substantial portion of the Antenna purchase price will ultimately be allocated to intangible assets, and that such assets are likely to include acquired core technology, customer related assets and goodwill. During the third quarter of 2013, the Company incurred direct and incremental expenses associated with the transaction of $0.5 million and expects to incur an additional estimated $2.2 million of such expenses that are primarily professional fees to affect the acquisition.
	The Company believes the acquisition will offer its collective clients faster time-to-market and increased flexibility in end-to-end mobile application development, powerful device management and cloud-based mobile Backend-as-a-Service.
