## Table 0 ##
On May 1, 2006, the Company completed its acquisition of Fluent Inc.  (“Fluent”), a global provider of computational fluid dynamics (“CFD”)-based computer-aided engineering software and services.
The acquisition of Fluent enhanced the breadth, functionality, usability and interoperability of the Company’s portfolio of simulation solutions.
Under the terms of the merger agreement, the Company issued 11,999,896 shares of its common stock, valued at approximately $274 million based on the average closing market price on the two days preceding and the two days following the announcement of the acquisition (February 16, 2006), and paid approximately $315 million in cash.
The total purchase price of approximately $598 million includes approximately $9 million in transaction fees.
The Company used a combination of existing cash and $198 million from committed bank financing to fund the transaction.
In addition to the $9 million in transactionrelated costs, the Company incurred financing costs of $1.9 million related to the long-term debt utilized to fund the acquisition.
The operating results of Fluent have been included in the Company’s consolidated financial statements since the date of acquisition, May 1, 2006.
The total purchase price was allocated to the foreign and domestic assets and liabilities of Fluent based upon management’s estimates of the fair market values of the assets acquired and the liabilities assumed.
The allocation included $213.9 million to identifiable intangible assets (including $88.0 million to developed software to be amortized over seven years, $65.9 million to customer contracts and related relationships to be amortized over nine and a half years, and $60.0 million to a non-amortizing trademark) and $404.3 million to goodwill, which is not tax deductible.
The Fluent trademark is one of the most recognized among CFD technologies.
The trademark represents a reputation of superior technical capability and strong support service that has been recognized by Fluent customers.
Because the trademark continues to gain strength in the marketplace today, as evidenced by increased sales of ANSYS FLUENT software over the past several years, the Company had originally expected the trademark to contribute to cash flows indefinitely and, accordingly, had assigned an indefinite life to the trademark.
The Company reconsidered the indefinite life associated with the Fluent trademark, as well as the trademark acquired in the 2003 acquisition of CFX, as part of the product and naming strategy changes that occurred as a result of the July 31, 2008 acquisition of Ansoft and determined that these trademarks had a remaining useful life of ten years.
Accordingly, on July 31, 2008, the Company began amortizing these trademarks over a ten-year period.
During the third quarter of 2008, the Company completed an impairment test for these trademarks and determined that these assets had not been impaired as of the test date, July 31, 2008.
In valuing deferred revenue on the Fluent balance sheet as of the acquisition date, the Company applied EITF No.01-3 and acquired deferred revenue of $31.5 million was recorded on the opening balance sheet.
This amount was $20.1 million lower than the historical carrying value.
Year Ended December 31, 2016 Compared to Year Ended December 31, 2015 Revenue:
## Table 1 ##
The Company's revenue increased 4.8% during the year ended December 31, 2016 as compared to the year ended December 31, 2015, while revenue grew 5.1% in constant currency.
The growth rate was favorably impacted by the Company's continued investment in its global sales, support and marketing organizations and was adversely impacted by a recent shift in the licensing preference of certain customers from perpetual licenses to lease licenses.
Lease license revenue increased 7.6% as compared to the prior year.
Perpetual license revenue, which is derived primarily from new sales, decreased 4.6% as compared to the prior year.
Annual maintenance contracts that were sold with new perpetual licenses, along with maintenance contracts sold with new perpetual licenses in previous years, contributed to maintenance revenue growth of 8.3%.
With respect to revenue, on average for the year ended December 31, 2016, the U. S.  Dollar was 0.5% stronger, when measured against the Company's primary foreign currencies, than for the year ended December 31, 2015.
The net overall strengthening resulted in decreased revenue of $2.2 million during the year ended December 31, 2016 as compared to the year ended December 31, 2015.
The impact on revenue was primarily driven by $5.6 million, $3.9 million, $1.7 million and $0.9 million of adverse impact due to a weaker Euro, British Pound, South Korean Won and Indian Rupee, respectively, partially offset by $10.4 million of favorable impact due to a stronger Japanese Yen.
The fluctuations in the U. S.  Dollar resulted in increased operating income of $0.9 million during the year ended December 31, 2016 as compared to the year ended December 31, 2015.
A substantial portion of the Company's license and maintenance revenue is derived from annual lease and maintenance contracts.
These contracts are generally renewed on an annual basis and typically have a high rate of customer renewal.
In addition to the recurring revenue base associated with these contracts, a majority of customers purchasing new perpetual licenses also purchase related annual maintenance contracts.
As a result of the significant recurring revenue base, the Company's license and maintenance revenue growth rate in any period does not necessarily correlate to the growth rate of new license and maintenance contracts sold during that period.
To the extent the rate of customer renewal for lease and maintenance contracts is high, incremental lease contracts, and maintenance contracts sold with new perpetual licenses, will result in license and maintenance revenue growth in constant currency.
Conversely, if the rate of renewal for these contracts is adversely affected by economic or other factors, the Company's license and maintenance growth will be adversely affected over the term that the revenue for those contracts would have otherwise been recognized.
The Company is starting to experience an increased interest by some of its larger customers in enterprise agreements that often include longer-term, time-based licenses involving a larger number of the Company's software products.
While these arrangements typically involve a higher overall transaction price, the revenue from these contracts is typically deferred and recognized over the period of the contract, resulting in increased deferred revenue and backlog.
To the extent these types of contracts replace sales of perpetual licenses, there could be a near-term adverse impact on software license and maintenance revenue growth.
The Company is similarly experiencing a shifting preference from perpetual licenses to time-based licenses across a broader spectrum of its customers, particularly in the more mature geographic markets, such as the U. S.  and Japan.
To the extent this shift continues or becomes more prevalent, the result could be a similar and incremental near-term adverse impact on software license and maintenance revenue growth.
International and domestic revenues, as a percentage of total revenue, were 62.8% and 37.2%, respectively, during the year ended December 31, 2016, and 62.4% and 37.6%, respectively, during the year ended December 31, 2015.
The Company derived 24.4% and 24.2% of its total revenue through the indirect sales channel for the years ended December 31, 2016 and 2015, respectively.
Contractual Obligations The Company's significant contractual obligations as of December 31, 2016 are summarized below:
## Table 2 ##
(1) On September 14, 2012, the Company entered into a lease agreement for 186,000 square feet of rentable space located in an office facility in Canonsburg, Pennsylvania, which serves as the Company's headquarters.
The lease was effective as of September 14, 2012, but because the leased premises were under construction, the Company was not obligated to pay rent until three months following the date that the leased premises were delivered to ANSYS, which occurred on October 1, 2014.
The term of the lease is 183 months, beginning on October 1, 2014.
The Company has a one-time right to terminate the lease effective upon the last day of the tenth full year following the date of possession (December 31, 2024) by providing the landlord with at least 18 months' prior written notice of such termination.
(2) Other operating leases primarily include noncancellable lease commitments for the Company's other domestic and international offices as well as certain operating equipment.
(3) Unconditional purchase obligations primarily include software licenses and long-term purchase contracts for network, communication and office maintenance services, which are unrecorded as of December 31, 2016.
(4) The Company has $18.4 million of unrecognized tax benefits, including estimated interest and penalties, that have been recorded as liabilities in accordance with income tax accounting guidance for which the Company is uncertain as to if or when such amounts may be settled.
As a result, such amounts are excluded from the table above.
(5) Other long-term obligations primarily include third-party commissions of $15.0 million, deferred compensation of $7.4 million (including estimated imputed interest of $161,000 within 1 year and $87,000 within 2-3 years) and postemployment benefits, including pension obligations, of $6.5 million for certain foreign locations of the Company.
These amounts include the related current portions when applicable.
Cash and Cash Equivalents Cash and cash equivalents consist primarily of highly liquid investments such as deposits held at major banks and money market funds with original maturities of three months or less.
Cash equivalents are carried at cost, which approximates fair value.
The Company's cash and cash equivalents balances comprise the following:
