Accounting Policies [Abstract]

Significant Accounting Policies

(a) Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Aspen Technology, Inc. and our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Reclassifications

Certain line items in prior period financial statements have been reclassified to conform to currently reported presentations.

(b) Management Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Cash and cash equivalents consist of short-term, highly liquid investments with remaining maturities of three months or less when purchased.

(d) Marketable Securities

The following table summarizes the fair value, the amortized cost and unrealized holding gains (losses) on our marketable securities as of June 30, 2016 and 2015:



	Fair Value		Cost		Unrealized Gains		Unrealized Losses
	(Dollars in Thousands)
June 30, 2016:
U.S. corporate bonds with maturities less than one year	$	3,006	$	3,006	$	—	$	—
Total short-term marketable securities	$	3,006	$	3,006	$	—	$	—
June 30, 2015:
U.S. corporate bonds with maturities less than one year	$	59,197	$	59,223	$	8	$	(34	)
Total short-term marketable securities	$	59,197	$	59,223	$	8	$	(34	)
U.S. corporate bonds with maturities greater than one year	$	3,047	$	3,055	$	—	$	(8	)
Total long-term marketable securities	$	3,047	$	3,055	$	—	$	(8	)

Our marketable securities are classified as available-for-sale and reported at fair value on the consolidated balance sheets. Net unrealized gains (losses) are reported as a separate component of accumulated other comprehensive income, net of tax. Realized gains and losses on investments are recognized in earnings as incurred. Our investments consist primarily of investment grade fixed income corporate debt securities with maturity dates in August 2016 as of June 30, 2016 and ranging from July 2015 through August 2016 as of June 30, 2015.

We review our marketable securities for impairment at each reporting period to determine if any of our securities have experienced an other-than-temporary decline in fair value in accordance with the provisions of ASC Topic 320, Investments—Debt and Equity Securities. We consider factors, such as the length of time and extent to which the market value has been less than the cost, the financial condition and near-term prospects of the issuer, our intent to sell, or whether it is more likely than not we will be required to sell the investment before recovery of its amortized cost basis. If we believe that an other-than-temporary decline in fair value has occurred, we write down the investment to fair value and recognize the credit loss in earnings and the non-credit loss in accumulated other comprehensive income. During fiscal 2016 and 2015, our marketable securities were not considered other-than-temporarily impaired and, as such, we did not recognize impairment losses during the periods then ended. Unrealized losses are attributable to changes in interest rates.

(e) Property and Equipment

Property and equipment are stated at cost. We provide for depreciation and amortization, primarily computed using the straight-line method, by charges to operations in amounts estimated to allocate the cost of the assets over their estimated useful lives, as follows:



Asset Classification	Estimated Useful Life
Computer equipment	3 years
Purchased software	3 - 5 years
Furniture and fixtures	3 - 10 years
Leasehold improvements	Life of lease or asset, whichever is shorter

(f) Revenue Recognition

Transition to the aspenONE Licensing Model

Prior to fiscal 2010, we offered term or perpetual licenses to specific products, or specifically defined sets of products, which we refer to as point products. The majority of our license revenue was recognized under an "upfront revenue model," in which the net present value of the aggregate license fees was recognized as revenue upon shipment of the point products, provided all revenue recognition criteria were met. Customers typically received one year of post-contract software maintenance and support, or SMS, with their license agreements and then could elect to renew SMS annually. Revenue from SMS was recognized ratably over the period in which the SMS was delivered.

In fiscal 2010, we introduced the following changes to our licensing model:

(i)

We began offering our software on a subscription basis, allowing our customers access to all products within a licensed suite (aspenONE Engineering or aspenONE Manufacturing and Supply Chain). SMS is included for the entire term of the arrangement and customers are entitled to any software products or updates introduced into the licensed suite. We refer to this license arrangement as our aspenONE licensing model.


(ii)	We began to include SMS for the entire term on our point product term arrangements.

In fiscal 2012, we introduced Premier Plus SMS. As part of this offering, customers receive 24x7 support, faster response times, dedicated technical advocates and access to web-based training modules. Premier Plus SMS is exclusively available as a component of our term contract arrangements and we are unable to establish VSOE for this deliverable because we don't offer it on a stand-alone basis.

Revenue related to our aspenONE licensing model and point product arrangements with Premier Plus SMS are both recognized over the term of the arrangement on a ratable basis. The changes to our licensing model resulted in a significant reduction to license revenue in fiscal 2010, as compared to fiscal periods preceding our licensing model changes. From fiscal 2010 through fiscal 2015, as customer license arrangements previously executed under the upfront revenue model reached the end of their terms and were renewed under the aspenONE licensing model, we recognized increasing amounts of subscription revenue and deferred revenue. The value of our installed base of software licenses was also growing during this period which further contributed to growth in subscription and deferred revenue. Many of our license arrangements were five or six years in duration when the aspenONE licensing model was introduced at the start of fiscal 2010, and consequently, a number of arrangements executed under the upfront revenue model did not reach the end of their original term until the end of fiscal 2015. The changes to our licensing model did not have any material impact on subscription revenue or deferred revenue for fiscal 2016 and we do not expect any material impact on subscription revenue or deferred revenue for fiscal 2017 and beyond.

The changes to our licensing model introduced in fiscal 2010 did not change the method or timing of customer billings or cash collections. In addition, the changes to our licensing model did not impact the incurrence or timing of our expenses. Since there was no corresponding expense reduction to offset the lower revenue during fiscal years 2010-2015, operating income was lower than what would have been reported under a fully transitioned revenue model.

Revenue Recognition

We generate revenue from the following sources: (1) Subscription and software revenue; and (2) Services and other revenue.

Four basic criteria must be satisfied before software license revenue can be recognized: persuasive evidence of an arrangement between us and an end user; delivery of our product has occurred; the fee for the product is fixed or determinable; and collection of the fee is probable.

Persuasive evidence of an arrangement—We use a signed contract as evidence of an arrangement for software licenses and SMS. For professional services we use a signed contract and a work proposal to evidence an arrangement. In cases where both a signed contract and a purchase order are required by the customer, we consider both taken together as evidence of the arrangement.

Delivery of our product—Software and the corresponding access keys are generally delivered to customers via disk media with standard shipping terms of Free Carrier, our warehouse (i.e., FCA, named place) or electronic delivery. Our software license agreements do not contain conditions for acceptance.

Fee is fixed or determinable—We assess whether a fee is fixed or determinable at the outset of the arrangement. Significant judgment is involved in making this assessment.

Under our historical upfront revenue model, we are able to demonstrate that the fees are fixed or determinable for all arrangements, including those for our term licenses that contain extended payment terms. We have an established history of collecting under the terms of these contracts without providing concessions to customers. In addition, we also assess whether a contract modification to an existing term arrangement constitutes a concession. In making this assessment, significant analysis is performed to ensure that no concessions are given. Our software license agreements do not include a right of return or exchange. For license arrangements executed under the historical upfront revenue model, we recognize license revenue upon delivery of the software product, provided all other revenue recognition requirements are met.

We cannot assert that the fees under our aspenONE licensing model and point product arrangements with Premier Plus SMS are fixed or determinable because the rights provided to customers, and the economics of the arrangements, are not comparable to our transactions with other customers under the upfront revenue model. As a result, the amount of revenue recognized for these arrangements is limited by the amount of customer payments that become due.

Collection of fee is probable—We assess the probability of collecting from each customer at the outset of the arrangement based on a number of factors, including the customer's payment history, its current creditworthiness, economic conditions in the customer's industry and geographic location, and general economic conditions. If in our judgment collection of a fee is not probable, revenue is recognized as cash is collected, provided all other conditions for revenue recognition have been met.

Vendor-Specific Objective Evidence of Fair Value

We have established VSOE for professional services and certain training offerings, but not for our software products or our SMS offerings. We assess VSOE for SMS, professional services, and training, based on an analysis of standalone sales of the offerings using the bell-shaped curve approach. We do not have a history of selling our Premier Plus SMS offering to customers on a standalone basis, and as a result are unable to establish VSOE for this deliverable. As of July 1, 2014, we are no longer able to establish VSOE for legacy SMS offerings sold with our perpetual license arrangements. As of July 1, 2015, we were no longer able to establish VSOE for SMS offerings sold with our legacy term license arrangements. As a result, all perpetual license agreements and legacy term agreements that include legacy SMS entered into subsequent to June 30, 2014 and June 30, 2015, respectively, will be recognized ratably over the legacy SMS service period. Loss of VSOE on legacy SMS offerings sold with our perpetual license and legacy term arrangements did not have a material impact on our revenue in fiscal 2016 and is not expected to have a material impact on our revenue in future periods.

We allocate the arrangement consideration among the elements included in our multi-element arrangements using the residual method. Under the residual method, the VSOE of the undelivered elements is deferred and the remaining portion of the arrangement fee is recognized as revenue upon delivery of the software, assuming all other revenue recognition criteria are met. If VSOE does not exist for an undelivered element in an arrangement, revenue is deferred until such evidence does exist for the undelivered elements, or until all elements are delivered, whichever is earlier. Under the historical upfront revenue model, the residual license fee is recognized upon delivery of the software provided all other revenue recognition criteria were met. Arrangements that qualified for upfront recognition during fiscal 2014 and prior periods included sales of perpetual licenses, amendments to existing legacy term arrangements and renewals of legacy term arrangements.

Subscription and Software Revenue

Subscription and software revenue consists of product and related revenue from our (i) aspenONE licensing model; (ii) point product arrangements with our Premier Plus SMS offering included for the contract term; (iii) legacy arrangements including (a) amendments to existing legacy term arrangements, (b) renewals of legacy term arrangements and (c) legacy arrangements that are being recognized over time as a result of not previously meeting one or more of the requirements for recognition under the upfront revenue model; (iv) legacy SMS arrangements; and (v) perpetual arrangements.

When a customer elects to license our products under our aspenONE licensing model, our Premier Plus SMS offering is included for the entire term of the arrangement and the customer receives, for the term of the arrangement, the right to any new unspecified future software products and updates that may be introduced into the licensed aspenONE software suite. Due to our obligation to provide unspecified future software products and updates, we are required to recognize revenue ratably over the term of the arrangement, once the other revenue recognition criteria noted above have been met.

Our point product arrangements with Premier Plus SMS include SMS for the term of the arrangement. Since we do not have VSOE for our Premier Plus SMS offering, the SMS element of our point product arrangements is not separable. As a result, revenue associated with point product arrangements with Premier Plus SMS included for the contract term is recognized ratably over the term of the arrangement, once the other revenue recognition criteria have been met.

Perpetual and legacy term license arrangements do not include the same rights as those provided to customers under the aspenONE licensing model and point product arrangements with Premier Plus SMS. Legacy SMS revenue is generated from legacy SMS offerings provided in support of perpetual and legacy term license arrangements. Customers typically receive SMS for one year and then can elect to renew SMS annually. During fiscal 2014 and prior periods, we had VSOE for certain legacy SMS offerings sold with perpetual and term license arrangements and could therefore separate the undelivered elements. Accordingly, license fee revenue for perpetual and legacy term license arrangements was recognized upon delivery of the software products using the residual method, provided all other revenue recognition requirements were met. VSOE of fair value for the undelivered SMS component sold with our perpetual and term license arrangements was deferred and subsequently amortized into revenue ratably over the contractual term of the SMS arrangement. As of July 1, 2014, we are no longer able to establish VSOE for our legacy SMS offerings sold with our perpetual license arrangements. As of July 1, 2015, we were no longer able to establish VSOE for SMS offerings sold with our legacy term license arrangements. As a result, all perpetual license agreements and legacy term agreements that include legacy SMS entered into subsequent to June 30, 2014 and June 30, 2015, respectively, will be recognized ratably over the legacy SMS service period. Loss of VSOE on legacy SMS offerings sold with our perpetual license and legacy term arrangements did not have a material impact on our revenue in fiscal 2016 and is not expected to have a material impact on our revenue in future periods.

Services and Other Revenue

Professional Services Revenue

Professional services are provided to customers on a time-and-materials (T&M) or fixed-price basis. We recognize professional services fees for our T&M contracts based upon hours worked and contractually agreed-upon hourly rates. Revenue from fixed-price engagements is recognized using the proportional performance method based on the ratio of costs incurred to the total estimated project costs. Project costs are typically expensed as incurred. The use of the proportional performance method is dependent upon our ability to reliably estimate the costs to complete a project. We use historical experience as a basis for future estimates to complete current projects. Additionally, we believe that costs are the best available measure of performance. Out-of-pocket expenses which are reimbursed by customers are recorded as revenue.

In certain circumstances, professional services revenue may be recognized over a longer time period than the period over which the services are performed. If the costs to complete a project are not estimable or the completion is uncertain, the revenue is recognized upon completion of the services. In circumstances in which professional services are sold as a single arrangement with, or in contemplation of, a new aspenONE license or point product arrangement with Premier Plus SMS, revenue is deferred and recognized on a ratable basis over the longer of (i) the period the services are performed, or (ii) the license term. When we provide professional services considered essential to the functionality of the software, we recognize the combined revenue from the sale of the software and related services using the completed contract or percentage-of-completion method.

We have occasionally been required to commit unanticipated additional resources to complete projects, which resulted in losses on those contracts. Provisions for estimated losses on contracts are made during the period in which such losses become probable and can be reasonably estimated.

Training Revenue

We provide training services to our customers, including on-site, Internet-based, public and customized training. Revenue is recognized in the period in which the services are performed. In circumstances in which training services are sold as a single arrangement with, or in contemplation of, a new aspenONE license or point product arrangement with Premier Plus SMS, revenue is deferred and recognized on a ratable basis over the longer of (i) the period the services are performed or (ii) the license term.

Deferred Revenue

Deferred revenue includes amounts billed or collected in advance of revenue recognition, including arrangements under the aspenONE licensing model, point product arrangements with Premier Plus SMS, legacy SMS arrangements, professional services, and training. Under the aspenONE licensing model and for point product arrangements with Premier Plus SMS, VSOE does not exist for the undelivered elements, and as a result, the arrangement fees are recognized ratably (i.e., on a subscription basis) over the term of the license. Deferred revenue is recorded as each invoice becomes due.

Other Licensing Matters

Our standard licensing agreements include a product warranty provision. We have not experienced significant claims related to software warranties beyond the scope of SMS support, which we are already obligated to provide, and consequently, we have not established reserves for warranty obligations.

Our agreements with our customers generally require us to indemnify the customer against claims that our software infringes third-party patent, copyright, trademark or other proprietary rights. Such indemnification obligations are generally limited in a variety of industry-standard respects, including our right to replace an infringing product. As of June 30, 2016 and 2015, we had not experienced any material losses related to these indemnification obligations and no claims with respect thereto were outstanding. We do not expect significant claims related to these indemnification obligations, and consequently, have not established any related reserves.

(g) Installments Receivable

Installments receivable resulting from product sales under the upfront revenue model are discounted to present value at prevailing market rates at the date the contract is signed, taking into consideration the customer's credit rating. The finance element is recognized using the effective interest method over the relevant license term and is classified as interest income. Current installments receivable consist of invoices with a due date of less than one year but greater than 45 days from the period-end date. Once an installments receivable invoice becomes due within 45 days, it is reclassified as a trade accounts receivable in our consolidated balance sheets. As a result, we did not have any past due installments receivable as of June 30, 2016.

Our non-current installments receivable are within the scope of Accounting Standards Update (ASU) No. 2010-20, Receivables (Topic 310): Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses. As our portfolio of financing receivables arises from the sale of our software licenses, the methodology for determining our allowance for doubtful accounts is based on the collective population of receivables and is not stratified by class or portfolio segment. We consider factors such as existing economic conditions, country risk, customers' credit rating and past payment history in determining our allowance for doubtful accounts. We reserve against our installments receivable when the related trade accounts receivable have been past due for over a year, or when there is a specific risk of uncollectability. Our specific reserve reflects the full value of the related installments receivable for which collection has been deemed uncertain. We transfer an installment receivable reserve balance into a trade accounts receivable allowance when an installment receivable ages into a trade account receivable.

We write-off receivables when they are considered uncollectable based on our judgment. In instances when we write-off specific customers' trade accounts receivable, we also write off any related current and non-current installments receivable balances.

As of June 30, 2016 and June 30, 2015, our current installments receivable of $0.3 million and $1.6 million, respectively, are included within prepaid expenses and other current assets in our consolidated balance sheets. As of June 30, 2015, our non-current installments receivable of $0.3 million is included within other non-current assets in our consolidated balance sheets.

Under the aspenONE licensing model and for point product arrangements with Premier Plus SMS included for the contract term, the installment payments are not considered fixed or determinable and, as a result, are not included as installments receivable on our consolidated balance sheet.

(h) Allowance for Doubtful Accounts and Discounts

We make judgments as to our ability to collect outstanding receivables and provide allowances for the portion of receivables when a loss is reasonably expected to occur. The allowance for doubtful accounts is established to represent the best estimate of the net realizable value of the outstanding accounts receivable. The development of the allowance for doubtful accounts is based on a review of past due amounts, historical write-off and recovery experience, as well as aging trends affecting specific accounts and general operational factors affecting all accounts. In addition, factors are developed utilizing historical trends in bad debts and allowances.

We consider current economic trends when evaluating the adequacy of the allowance for doubtful accounts. If circumstances relating to specific customers change or unanticipated changes occur in the general business environment, our estimates of the recoverability of receivables could be further adjusted.

The following table presents our allowance for doubtful accounts activity for accounts receivable in fiscal 2016 and 2015, respectively:



	Year Ended June 30,
	2016			2015
	(Dollars in Thousands)
Balance, beginning of year	$	1,636		$	3,465
Provision for bad debts	1,032			(1,032		)
Write-offs	(1,064		)	(797		)
Balance, end of year	$	1,604		$	1,636

The following table summarizes our accounts receivable, net of the related allowance for doubtful accounts, as of June 30, 2016 and 2015:



	Gross		Allowance		Net
	(Dollars in Thousands)
June 30, 2016:
Accounts Receivable	$	22,080	$	1,604	$	20,476
	$	22,080	$	1,604	$	20,476
June 30, 2015:
Accounts Receivable	$	32,357	$	1,636	$	30,721
	$	32,357	$	1,636	$	30,721

(i) Fair Value of Financial Instruments

We determine fair value of financial and non-financial assets and liabilities in accordance with provisions of ASC Topic 820, Fair Value Measurements and Disclosures (ASC 820). ASC 820 defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. ASC 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities, and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 Inputs—Inputs other than quoted prices included in Level 1 that are observable for an asset or a liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for an asset or a liability (such as interest rates, yield curves, volatilities, prepayment speeds, credit risks, etc.), or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3 Inputs—Unobservable inputs for determining fair values of assets or liabilities that reflect an entity's own assumptions in pricing assets or liabilities.

Cash Equivalents. Cash equivalents are reported at fair value utilizing quoted market prices in identical markets, or "Level 1 Inputs." Our cash equivalents consist of short-term, highly liquid investments with remaining maturities of three months or less when purchased.

Marketable Securities. Marketable securities are reported at fair value calculated in accordance with the market approach, utilizing market consensus pricing models with quoted prices that are directly or indirectly observable, or "Level 2 Inputs".

Financial instruments not measured or recorded at fair value in the accompanying consolidated financial statements consist of cash, accounts receivable, installments receivable, accounts payable and accrued liabilities. The estimated fair value of these financial instruments approximates their carrying value. The estimated fair value of the borrowings under the credit agreement approximates its carrying value due to the floating interest rate.

The following table summarizes financial assets and financial liabilities measured and recorded at fair value on a recurring basis in the accompanying consolidated balance sheets as of June 30, 2016 and 2015, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:



	Fair Value Measurements at Reporting Date Using,
	Quoted Prices in Active Markets for Identical Assets (Level 1 Inputs)		Significant Other Observable Inputs (Level 2 Inputs)
	(Dollars in Thousands)
June 30, 2016:
Cash equivalents	$	286,200	$	—
Marketable securities	—		3,006
June 30, 2015:
Cash equivalents	$	130,232	$	—
Marketable securities	—		62,244

At June 30, 2016 and 2015, we did not have any assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs ("Level 3 Inputs").

Certain non-financial assets, including goodwill, finite-lived intangible assets and other non-financial long-lived assets, are measured at fair value using market and income approaches on a non-recurring basis when there is an indication of impairment.

(j) Computer Software Development Costs

Certain computer software development costs are capitalized in the accompanying consolidated balance sheets. Capitalization of computer software development costs begins upon establishing technological feasibility defined as meeting specifications determined by the program design. Amortization of capitalized computer software development costs is provided on a product-by-product basis using the greater of (a) the amount computed using the ratio that current gross revenue for a product bears to total of current and anticipated future gross revenue for that product or (b) the straight-line method, beginning upon commercial release of the product, and continuing over the remaining estimated economic life of the product, not to exceed three years.

Total computer software costs capitalized were $0.3 million, $0.4 million and $0.7 million during the years ended June 30, 2016, 2015 and 2014, respectively. Total amortization expense charged to operations was approximately $0.6 million, $0.7 million and $1.0 million for the years ended June 30, 2016, 2015 and 2014, respectively. Computer software development accumulated amortization totaled $73.8 million and $73.3 million as of June 30, 2016 and 2015, respectively. Weighted average remaining useful life of computer software development costs was 0.7 years and 1.1 years at June 30, 2016 and 2015, respectively.

At each balance sheet date, we evaluate the unamortized capitalized software costs for potential impairment by comparing the balance to the net realizable value of the products. During the years ending June 30, 2016, 2015 and 2014, our computer software development costs were not considered impaired and as such, we did not recognize impairment losses during the periods then ended.

(k) Foreign Currency Translation

The determination of the functional currency of subsidiaries is based on the subsidiaries' financial and operational environment and is the local currency of the subsidiary. Gains and losses from foreign currency translation related to entities whose functional currency is their local currency are credited or charged to accumulated other comprehensive income included in stockholders' (deficit) equity in the consolidated balance sheets. In all instances, foreign currency transaction and remeasurement gains or losses are credited or charged to the consolidated statements of operations as incurred as a component of other income (expense), net. Net foreign currency transaction and remeasurement gains (losses) were less than $0.1 million, $(0.8) million and $(2.3) million in fiscal 2016, 2015 and 2014, respectively. Fiscal 2016 other income (expense), net included $3.4 million of foreign currency exchange losses related to the Acquisition Bid (refer to Note 4, Acquisitions, for further discussion).

(l) Net Income Per Share

Basic income per share is determined by dividing net income by the weighted average common shares outstanding during the period. Diluted income per share is determined by dividing net income by diluted weighted average shares outstanding during the period. Diluted weighted average shares reflect the dilutive effect, if any, of potential common shares. To the extent their effect is dilutive, employee equity awards and other commitments to be settled in common stock are included in the calculation of diluted income per share based on the treasury stock method.

For the years ended June 30, 2016, 2015 and 2014, certain employee equity awards were anti-dilutive based on the treasury stock method. The calculations of basic and diluted net income (loss) per share and basic and diluted weighted average shares outstanding are as follows:



	Year Ended June 30,
	2016		2015		2014
	(Dollars and Shares in Thousands, Except per Share Data)
Net income	$	139,951	$	118,407	$	85,783
Weighted average shares outstanding	82,892		88,398		92,648
Dilutive impact from:
Employee equity awards	417		618		1,017
Dilutive weighted average shares outstanding	83,309		89,016		93,665
Income per share
Basic	$	1.69	$	1.34	$	0.93
Dilutive	$	1.68	$	1.33	$	0.92

The following potential common shares were excluded from the calculation of dilutive weighted average shares outstanding because their effect would be anti-dilutive at the balance sheet date:



	Year Ended June 30,
	2016	2015	2014
	(Shares in Thousands)
Employee equity awards	1,028	587	291

(m) Concentration of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk are principally cash and cash equivalents, marketable securities, accounts receivable and installments receivable. Our cash is held in financial institutions and our cash equivalents are invested in money market mutual funds that we believe to be of high credit quality. At June 30, 2016, our investments in marketable securities consist primarily of investment grade fixed income corporate debt securities with maturities of less than 2 months. We diversify our investment portfolio by investing in multiple types of investment-grade securities and attempt to mitigate a risk of loss by using a third-party investment manager.

Concentration of credit risk with respect to receivables is limited to certain customers to which we make substantial sales. To reduce risk, we assess the financial strength of our customers. We do not require collateral or other security in support of our receivables. As of June 30, 2016, we had two customer receivable balances that represented approximately 10% and 15% of our total receivables. As of June 30, 2015, we had one customer receivable balance that represented approximately 11% of our total receivables and was collected subsequent to June 30, 2015.

(n) Computer Software Developed for Internal Use and Long-Lived Assets

Computer Software Developed for Internal Use:

Computer software developed for internal use is capitalized in accordance with ASC Topic 350-40, Intangibles Goodwill and Other—Internal Use Software. We capitalize direct labor costs incurred to develop internal-use software during the application development stage after determining software technological requirements and obtaining management approval for funding projects probable of completion.

In fiscal 2016 there were no capitalized direct labor costs associated with our development of software for internal use. In fiscal 2015 and 2014, we capitalized direct labor costs of $0.3 million and $0.8 million, respectively, associated with our development of software for internal use. These costs are included within property, plant and equipment in our consolidated balance sheets.

Impairment of Long-Lived Assets:

We evaluate our long-lived assets, which include finite-lived intangible assets, property and leasehold improvements for impairment as events and circumstances indicate that the carrying amount of an asset or a group of assets may not be recoverable. We assess the recoverability of the asset or a group of assets based on the undiscounted future cash flows the asset is expected to generate, and recognize an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset are less than its carrying value. If an asset or a group of assets are deemed to be impaired, the amount of the impairment loss, if any, represents the excess of the asset's or a group of assets' carrying value compared to their estimated fair values.

(o) Comprehensive Income

Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) and its components for fiscal 2016, 2015 and 2014 are disclosed in the accompanying consolidated statements of comprehensive income.

As of June 30, 2016, 2015 and 2014, accumulated other comprehensive income is comprised of foreign translation adjustments of $2.7 million, $6.5 million $9.4 million, respectively, and net unrealized gains (losses) on available for sale securities of less than ($0.1) million, $(0.1) million and $0.1 million, respectively.

(p) Accounting for Stock-Based Compensation

Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the vesting period.

(q) Income Taxes

Deferred income taxes are recognized based on temporary differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using the statutory tax rates and laws expected to apply to taxable income in the years in which the temporary differences are expected to reverse. Valuation allowances are provided against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the timing of the temporary differences becoming deductible. Management considers, among other available information, scheduled reversals of deferred tax liabilities, projected future taxable income, limitations of availability of net operating loss carryforwards, and other matters in making this assessment.

We do not provide deferred taxes on unremitted earnings of foreign subsidiaries since we intend to indefinitely reinvest either currently or sometime in the foreseeable future. Unrecognized provisions for taxes on undistributed earnings of foreign subsidiaries, which are considered indefinitely reinvested, are not material to our consolidated financial position or results of operations. We are continuously subject to examination by the IRS, as well as various state and foreign jurisdictions. The IRS and other taxing authorities may challenge certain deductions and credits reported by us on our income tax returns. In accordance with provisions of ASC Topic 740, Income Taxes (ASC 740), an entity should recognize a tax benefit when it is more-likely-than-not, based on the technical merits, that the position would be sustained upon examination by a taxing authority. The amount to be recognized, if the more-likely-than-not threshold was passed, should be measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. Furthermore, any change in the recognition, de-recognition or measurement of a tax position should be recorded in the period in which the change occurs. We account for interest and penalties related to uncertain tax positions as part of the provision for income taxes.

(r) Loss Contingencies

We accrue estimated liabilities for loss contingencies arising from claims, assessments, litigation and other sources when it is probable that a liability has been incurred and the amount of the claim assessment or damages can be reasonably estimated. We believe that we have sufficient accruals to cover any obligations resulting from claims, assessments or litigation that have met these criteria. Refer to Note 12 for discussion of these matters and related liability accruals.

(s) Advertising Costs

Advertising costs are expensed as incurred and are classified as sales and marketing expenses. We incurred advertising expenses of $2.3 million, $2.9 million and $2.1 million during fiscal 2016, 2015 and 2014, respectively.

(t) Research and Development Expense

We charge research and development expenditures to expense as the costs are incurred. Research and development expenses consist primarily of personnel expenses related to the creation of new products, enhancements and engineering changes to existing products and costs of acquired technology prior to establishing technological feasibility.

During fiscal 2016, 2015 and 2014, we acquired certain technologies for $0.3 million, $3.3 million and $4.9 million, respectively. At the time we acquired the technology, the project to develop a commercially available product did not meet the definition of having reached technological feasibility and as such, the entire cost of the acquired technology was expensed as research and development expense.

(u) Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 was issued by the FASB as a part of the joint project with the International Accounting Standards Board (IASB) to clarify revenue recognition principles and develop a common revenue standard for the U.S. Generally Accepted Accounting Principles (GAAP) and International Financial Reporting Standards (IFRS). ASU No. 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption of ASU No. 2014-09 is permitted but not before December 15, 2016. The amendments included within ASU No. 2014-09 should be applied by using one of the following methods:

Retrospectively to each prior reporting period presented. The entity may elect any of the practical expedients described in ASU No. 2014-09 when applying this method.

Retrospectively with the cumulative effect of initially applying ASU No. 2014-09 recognized at the date of initial application. In the reporting periods that include the date of the initial application of ASU No. 2014-09, the entity should disclose the amount by which each financial statement line item is affected by the application of ASU No. 2014-09 in the current reporting period as compared to the guidance that was in effect before the change.

We will adopt ASU No. 2014-09 during the first quarter of fiscal 2019. We are currently evaluating the impact of ASU No. 2014-09 on our financial position, results of operations and cash flows.

In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. The amendment provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for a cloud computing arrangement as a service contract. The amendment will be effective for annual reporting periods beginning on or after December 15, 2015. We are currently evaluating the impact of ASU No. 2015-05 on our financial position, results of operations and cash flows.

In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 amends current presentation guidance by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Prior to the issuance of ASU No. 2015-03, debt issuance costs were required to be presented as an asset on the balance sheet. In August 2015, the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. ASU No. 2015-15 states that debt issuance costs related to line of credit arrangements can be presented as an asset, similar to the treatment prior to the issuance of ASU No. 2015-03. We adopted the provisions of ASU No. 2015-03 and ASU No. 2015-15 during the second quarter of fiscal 2016. As of June 30, 2016, the issuance costs related to our Credit Agreement (as described in Note 9) were recorded in prepaid expenses and other current assets in our consolidated balance sheet. Adjustments to prior periods to conform to the current period presentation were not required as we did not have deferred finance costs on the balance sheet in prior periods.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, which eliminates the requirement for an acquirer to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. The ASU instead requires an acquirer to recognize a measurement-period adjustment during the period in which it determines the amount of the adjustment. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. We adopted ASU No. 2015-16 during the second quarter of fiscal 2016. The adoption of ASU No. 2015-16 did not have a material impact our consolidated financial position, results of operations or cash flows.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which simplifies the presentation of deferred income taxes by removing the requirement to bifurcate deferred income tax assets and liabilities between current and non-current. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2016. Early adoption is permitted. The Company elected early adoption in the fourth quarter of fiscal 2016, and deferred income tax assets and liabilities are presented as non-current in the consolidated balance sheets at June 30, 2016. This adoption was applied prospectively and prior periods have not been reclassified.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under the amendment, lessees will be required to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted. We are currently evaluating the impact of ASU No. 2016-02 on our financial position, results of operations and cash flows.

In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). The amendment clarifies the implementation guidance for principal versus agent considerations as contained in ASU No. 2014-09, Revenue from Contracts with Customers. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to a customer. ASU No. 2016-08 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption of ASU No. 2016-08 is permitted but not before December 15, 2016. We will adopt ASU No. 2016-08 during the first quarter of fiscal 2019. We are currently evaluating the impact of ASU No. 2016-08 on our financial position, results of operations and cash flows.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendment identifies several areas for simplification applicable to entities that issue share-based payment awards to their employees, including income tax consequences, the option to recognize gross stock compensation expense with actual forfeitures recognized when they occur, and certain classifications on the statements of cash flows. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2016. Early adoption is permitted. We are currently evaluating the impact of ASU No. 2016-09 on our financial position, results of operations and cash flows.

Property and Equipment

Property, equipment and leasehold improvements in the accompanying consolidated balance sheets consist of the following:



	Year Ended June 30,
	2016			2015
	(Dollars in Thousands)
Property, equipment and leasehold improvements—at cost:
Computer equipment	$	10,387		$	11,614

During fiscal 2016, we wrote off fully depreciated property, equipment and leasehold improvements that were no longer in use with gross book values of $3.0 million.

Depreciation expense was $5.1 million, $4.7 million and $3.3 million for fiscal 2016, 2015 and 2014, respectively.

We account for asset retirement obligations in accordance with ASC Topic 410, Asset Retirement and Environmental Obligations. Our asset retirement obligations relate to leasehold improvements for leased properties. The balance of our asset retirement obligations was $0.9 million and $0.6 million as of June 30, 2016 and 2015, respectively.

Acquisitions

Business Combinations [Abstract]

Acquisitions

In January 2016 we placed an offer to acquire the share capital of KBC Advanced Technologies plc (“KBC”) for 185 Pence Sterling per share, which valued KBC at approximately £158 million ("the Acquisition Bid"). The Acquisition Bid was to have been funded by cash on hand of approximately $91.0 million, which was held in escrow, and $140.0 million to be funded by a credit facility. On February 26, 2016, we entered into a $250.0 million credit agreement (the “Credit Agreement”) and borrowed $140.0 million (refer to Note 9 for further discussion of the Credit Agreement). In February 2016, KBC announced it had agreed to accept an acquisition offer of 210 Pence Sterling per share from Yokogawa Electric Corporation (“Yokogawa”) and we announced we did not intend to revise our offer. In April 2016 KBC was acquired by Yokogawa. A portion of the escrow balance was held in GBP for a period of time, which resulted in foreign exchange losses. During the year ended June 30, 2016, we incurred $5.2 million of costs related to the Acquisition Bid, as well as $3.4 million of foreign exchange losses, which were recognized in our results of operations as a component of general and administrative expenses and other income (expense), net, respectively.

In June 2016, we completed the acquisition of all the outstanding shares of Fidelis Group, LLC ("Fidelis"), a provider of asset reliability software used to predict and optimize asset performance. The purchase price consisted of $8.0 million of cash paid at closing and up to $2.0 million payment to be paid in December 2017.

A preliminary allocation of the purchase price is as follows. The valuation of acquired intangible assets and the deferred tax liabilities are considered preliminary as of June 30, 2016.



	Amount
	(Dollars in Thousands)
Tangible assets acquired, net	$	65
Identifiable intangible assets:
Developed technology	1,100
Customer relationships	700
In-process Research and Development	3,200

Goodwill	6,784
Deferred tax liabilities, net	(1,849		)
Total assets acquired	$	10,000

We used the income approach to determine the values of the identifiable intangible assets. The weighted-average discount rate (or rate of return) used to determine the value of the Fidelis intangible assets was 18% and the effective tax rate used was 34%. The values of the developed technology, in-process research and development and customer relationships are being amortized on a straight-line basis over their estimated useful lives of 10.0 years, 11.0 years and 8.0 years, respectively. The in-process research and development will begin amortization upon completion, which is expected in fiscal 2017. The weighted-average amortization period for these amortizable identifiable intangible assets is approximately 10.4 years.

The goodwill, which is not deductible for tax purposes, reflects the value of the assembled workforce and the company-specific synergies we expect to realize by selling Fidelis products and services to our existing customers. The results of operations of Fidelis have been included prospectively in our results of operations since the date of acquisition. Our results of operations giving effect to the Fidelis acquisition as if it had occurred at the beginning of fiscal 2016 would not differ materially from reported results.

Goodwill and Intangible Assets Disclosure [Abstract]

Intangible Assets

We include in our amortizable intangible assets those intangible assets acquired in our business and asset acquisitions. We amortize acquired intangible assets with finite lives over their estimated economic lives, generally using the straight-line method. Each period, we evaluate the estimated remaining useful lives of acquired intangible assets to determine whether events or changes in circumstances warrant a revision to the remaining period of amortization. Acquired intangibles are removed from the accounts when fully amortized and no longer in use.

Intangible assets consist of the following as of June 30, 2016 and 2015:



	Gross Carrying Amount		Accumulated Amortization			Effect of currency translation			Net Carrying Amount		Weighted Average Remaining Life (in Years)
	(Dollars in Thousands)
June 30, 2016:
Technology and patents	$	3,696	$	(2,046	)	$	(550	)	$	1,100	10.0
In process research & development	3,200		—			—			$	3,200	11.0
Customer relationships	700		—			—			$	700	8.0
Total	$	7,596	$	(2,046	)	$	(550	)	$	5,000	10.4
June 30, 2015:
Technology and patents	$	2,596	$	(2,646	)	$	197		$	147	0.4
Total	$	2,596	$	(2,646	)	$	197		$	147	0.4

Amortization expense for technology and patents is included in operating expenses and amounted to $0.1 million, $0.7 million and $0.9 million in fiscal 2016, 2015 and 2014, respectively. Amortization expense is expected to be approximately $0.2 million in fiscal 2017, $0.5 million in fiscal 2018, $0.5 million in fiscal 2019, $0.5 million in fiscal 2020, $0.5 million in fiscal 2021, and $2.8 million thereafter.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

The changes in the carrying amount of goodwill for our subscription and software reporting unit during fiscal years ending June 30, 2016 and 2015 were as follows:



	Amount
	(Dollars in Thousands)
Balance as of June 30, 2014:
Goodwill	$	84,845
Accumulated impairment losses	(65,569		)
	$	19,276
Effect of currency translation	(1,916		)
Balance as of June 30, 2015:
Goodwill	$	82,929
Accumulated impairment losses	(65,569		)
	$	17,360
Acquisition	6,784
Effect of currency translation	(706		)
Balance as of June 30, 2016:
Goodwill	$	89,007
Accumulated impairment losses	(65,569		)
	$	23,438

We test goodwill for impairment annually (or more often if impairment indicators arise), at the reporting unit level. We first assess qualitative factors to determine whether the existence of events or circumstances indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If we determine based on this assessment that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we perform the two-step goodwill impairment test. The first step requires us to determine the fair value of the reporting unit and compare it to the carrying amount, including goodwill, of such reporting unit. If the fair value exceeds the carrying amount, no impairment loss is recognized. However, if the carrying amount of the reporting unit exceeds its fair value, the goodwill of the unit may be impaired. The amount of impairment, if any, is measured based upon the implied fair value of goodwill at the valuation date.

Fair value of a reporting unit is determined using a combined weighted average of a market-based approach (utilizing fair value multiples of comparable publicly traded companies) and an income-based approach (utilizing discounted projected cash flows). In applying the income-based approach, we would be required to make assumptions about the amount and timing of future expected cash flows, growth rates and appropriate discount rates. The amount and timing of future cash flows would be based on our most recent long-term financial projections. The discount rate we would utilize would be determined using estimates of market participant risk-adjusted weighted-average costs of capital and reflect the risks associated with achieving future cash flows.

We have elected December 31st as the annual impairment assessment date and perform additional impairment tests if triggering events occur. We performed our annual impairment test for the subscription and software reporting unit as of December 31, 2015 and, based upon the results of our qualitative assessment, determined that it was not likely that its fair value was less than its carrying amount. As such, we did not perform the two-step goodwill impairment test and did not recognize impairment losses as a result of our analysis. If an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value, goodwill will be evaluated for impairment between annual tests. No triggering events indicating goodwill impairment occurred during fiscal 2016, 2015 and 2014.

Credit Agreement	12 Months Ended
Credit Agreement	Jun. 30, 2016
Debt Disclosure [Abstract]
Credit Agreement	Credit Agreement On February 26, 2016, we entered into a $250.0 million Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent, Silicon Valley Bank, as syndication agent, and the lenders and other parties named therein (the “Lenders”). The indebtedness evidenced by the Credit Agreement matures on February 26, 2021. Prior to the maturity of the Credit Agreement, any amounts borrowed may be repaid and, subject to the terms and conditions of the Credit Agreement, borrowed again in whole or in part without penalty. As of June 30, 2016, we had $140.0 million in outstanding borrowings under the Credit Agreement. Borrowings under the Credit Agreement bear interest at a rate equal to either, at our option, the sum of (a) the highest of (1) the rate of interest publicly announced by JPMorgan Chase Bank, N.A. as its prime rate in effect, (2) the Federal Funds Effective Rate plus 0.5%, and (3) the one-month Adjusted LIBO Rate plus 1.0%, plus (b) a margin initially of 0.5% for the first full fiscal quarter ending after the date of the Credit Agreement and thereafter based on our Leverage Ratio; or the Adjusted LIBO Rate plus a margin initially of 1.5% for the first full fiscal quarter ending after the date of the Credit Agreement and thereafter based on our Leverage Ratio. We must also pay, on a quarterly basis, an unused commitment fee at a rate of between 0.2% and 0.3% per annum, based on our Leverage Ratio. The interest rate as of June 30, 2016 was 1.96%. All borrowings under the Credit Agreement are secured by liens on substantially all of our assets. The Credit Agreement contains affirmative and negative covenants customary for facilities of this type, including restrictions on: incurrence of additional debt; liens; fundamental changes; asset sales; restricted payments; and transactions with affiliates. The Credit Agreement contains financial covenants regarding maintenance as of the end of each fiscal quarter, commencing with the quarter ending June 30, 2016, of a maximum Leverage Ratio of 3.0 to 1.0 and a minimum Interest Coverage Ratio of 3.0 to 1.0. We were in compliance with all covenants as of June 30, 2016.

Stock-Based Compensation

Stock-Based Compensation

Stock Compensation Plans

In April 2010, the shareholders approved the establishment of the 2010 Equity Incentive Plan (the 2010 Plan), which provides for the issuance of a maximum of 7,000,000 shares of common stock. The 2010 Plan provides for the grant of incentive and nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-related awards, and performance awards that may be settled in cash, stock, or other property. As of June 30, 2016, there were 3,537,843 shares of common stock available for issuance subject to awards under the 2010 Plan.

In May 2005, the shareholders approved the establishment of the 2005 Stock Incentive Plan (the 2005 Plan), which provides for the issuance of a maximum of 4,000,000 shares of common stock. The 2005 Plan provides for the grant of incentive and nonqualified stock options and other stock-based awards, including the grant of shares based upon certain conditions, the grant of securities convertible into common stock and the grant of stock appreciation rights. Restricted stock and other stock-based awards granted under the 2005 Plan may not exceed, in the aggregate, 4,000,000 shares of common stock. The 2005 Plan expired on March 31, 2015.

General Award Terms

We issue stock options and restricted stock units (RSUs) to our employees and outside directors, pursuant to shareholder-approved equity compensation plans. Option awards are granted with an exercise price equal to the market closing price of our stock on the trading day prior to the grant date. Those options generally vest over four years and expire within 7 or 10 years of grant. RSUs generally vest over four years. Historically, our practice has been to settle stock option exercises and RSU vesting through newly-issued shares.

Stock Compensation Accounting

Our stock-based compensation is accounted for as awards of equity instruments. Our policy is to issue new shares upon the exercise of stock awards. We use the "with-and-without" approach for determining if excess tax benefits are realized under ASC 718.

We utilize the Black-Scholes option valuation model for estimating the fair value of options granted. The Black-Scholes option valuation model incorporates assumptions regarding expected stock price volatility, the expected life of the option, the risk-free interest rate, dividend yield and the market value of our common stock. The expected stock price volatility is determined based on our stock's historic prices over a period commensurate with the expected life of the award. The expected life of an option represents the period for which options are expected to be outstanding as determined by historic option exercises and cancellations. The risk-free interest rate is based on the U.S. Treasury yield curve for notes with terms approximating the expected life of the options granted. The expected dividend yield is zero, based on our history and expectation of not paying dividends on common shares. We recognize compensation costs on a straight-line basis, net of estimated forfeitures, over the requisite service period for time-vested awards.

The weighted average estimated fair value of option awards granted during fiscal 2016, 2015 and 2014 was $13.16, $13.43 and $11.56 respectively.

We utilized the Black-Scholes option valuation model with the following weighted average assumptions:



	Year Ended June 30,
	2016		2015		2014
Risk-free interest rate	1.4	%	1.5	%	1.3	%
Expected dividend yield	None		None		None
Expected life (in years)	4.6		4.6		4.6
Expected volatility factor	34	%	35	%	39	%

The stock-based compensation expense and its classification in the accompanying consolidated statements of operations for fiscal 2016, 2015 and 2014 was as follows:



	Year Ended June 30,
	2016		2015		2014

During fiscal 2016, 2015 and 2014, the weighted average grant-date fair value of RSUs granted was $41.86, $42.65 and $33.07, respectively. During fiscal 2016, 2015 and 2014 the total fair value of vested shares from RSU grants amounted to $12.7 million, $16.1 million and $22.2 million, respectively.

As of June 30, 2016, the total future unrecognized compensation cost related to stock options and RSUs was $5.4 million and $17.8 million, respectively, and both are expected to be recorded over a weighted average period of 2.5 years.

Deferred tax assets (liabilities) consist of the following at June 30, 2016 and 2015:



	Year Ended June 30,

Valuation allowance	(10,119		)	(10,144		)
Net deferred tax assets	$	11,887		$	16,265

Reflected in the deferred tax assets above at June 30, 2016, we have foreign net operating loss carryforwards of $6.9 million some of which will expire beginning in 2019 and others with unlimited carryforwards, state research and development credits of $1.2 million which begin to expire in 2025, and U.S. federal alternative minimum tax credit carryforwards of $0.4 million which has an unlimited carryforward.

In fiscal 2016 and fiscal 2015, we recorded reductions in the income taxes payable of $2.2 million and $37.0 million, respectively, with an increase to additional paid in capital, for the benefits of excess stock-based compensation deductions recognized during the period in the United States and United Kingdom.

Our valuation allowance for deferred tax assets was $10.1 million and $10.1 million as of June 30, 2016 and 2015 respectively. The most significant portion of the valuation allowance is attributable to a reserve against US capital loss carryforward deferred tax asset of $8.1 million.

We have determined that we underwent an ownership change (as defined under section 382 of the Internal Revenue Code of 1986, as amended) during fiscal 2011. As such, the utilization of certain tax attributes is subject to an annual limitation. The annual limitation is not expected to impact the realizability of the deferred tax assets.

For fiscal 2016, our income tax provision included amounts determined under the provisions of ASC 740 intended to satisfy additional income tax assessments, including interest and penalties, that could result from any tax return positions for which the likelihood of sustaining the position on audit does not meet a threshold of "more likely than not." Tax liabilities were recorded as a component of our income taxes payable and other non-current liabilities. The ultimate amount of taxes due will not be known until examinations are completed and settled or the audit periods are closed by statutes.

A reconciliation of the reserve for uncertain tax positions is as follows:



	Year Ended June 30,
	2016			2015			2014
	(Dollars in Thousands)
Uncertain tax positions, beginning of year	$	19,870		$	21,193		$	22,031
Gross increases—tax positions in prior period	67			238			112
Gross increases—tax positions in current period	5,474			—			—
Gross decreases—lapse of statutes	(1,772		)	(1,024		)	(823		)
Currency translation adjustment	(104		)	(537		)	(127		)
Uncertain tax positions, end of year	$	23,535		$	19,870		$	21,193

At June 30, 2016, the total amount of unrecognized tax benefits is $23.5 million. Upon being recognized, the amount would reduce the effective tax rate. Our policy is to recognize interest and penalties related to income tax matters as provision for (benefit from) income taxes. At June 30, 2016, we had approximately $1.2 million of accrued interest and $0.8 million of penalties related to uncertain tax positions. We recorded a benefit for interest and penalties of approximately $0.8 million during fiscal 2016.

During the fourth quarter of fiscal 2016, we were notified by the Internal Revenue Services (“IRS”) that the fiscal 2015 U.S. federal income tax return will be audited. We believe our allowances for income tax contingencies are adequate and do not expect final resolution of the audit for approximately 12 months. Based on the information currently available, we do not anticipate a significant increase or decrease to our tax contingencies. We also continue to be subject to examination by the IRS for tax years 2007 to 2015.

We are subject to income tax in many jurisdictions outside the U.S. Our operations in certain jurisdictions remain subject to examination for tax years 2006 to 2015, some of which are currently under audit by local tax authorities. The resolutions of these audits are not expected to be material to our consolidated financial statements.

Commitments and Contingencies

Operating Leases

We lease certain facilities and various office equipment under non-cancellable operating leases with terms in excess of one year. Rental expense, including short term leases, maintenance charges and taxes on leased facilities, was approximately $8.3 million, $8.3 million and $7.1 million for fiscal years 2016, 2015 and 2014, respectively.

Future minimum lease payments under these leases as of June 30, 2016 are as follows:



Year Ended June 30,	Operating Leases
	(Dollars in Thousands)
2017	$	5,973
2018	6,815
2019	7,475
2020	6,979
2021	5,733
Thereafter	16,703
Total	$	49,678

Standby letters of credit for $3.5 million secure our performance on professional services contracts and certain facility leases. The letters of credit expire at various dates through fiscal 2025.

Legal Matters

In the ordinary course of business, we are, from time to time, involved in lawsuits, claims, investigations, proceedings and threats of litigation. These matters include an April 2004 claim by a customer that certain of our software products and implementation services failed to meet the customer's expectations. In March 2014, a judgment was issued by the trial court against us in the amount of approximately 1.9 million Euro ("€") plus interest and a portion of legal fees. We subsequently filed an appeal of that judgment. As of June 2016, the appellate court determined that we are liable for damages in the amount of approximately €1.7 million plus interest, with the possibility of additional damages to be determined in further proceedings by the appellate court.

While the outcome of the proceedings and claims referenced above cannot be predicted with certainty, there are no such matters, as of June 30, 2016 that, in the opinion of management, are reasonably possible to have a material adverse effect on our financial position, results of operations or cash flows. Liabilities, if applicable, related to the aforementioned matters discussed in this Note have been included in our accrued liabilities at June 30, 2016, and are not material to our financial position for the periods then ended. As of June 30, 2016, we do not believe that there is a reasonable possibility of a material loss exceeding the amounts already accrued for the proceedings or matters discussed above. However, the results of litigation (including the above-referenced appeal) and claims cannot be predicted with certainty; unfavorable resolutions are possible and could materially affect our results of operations, cash flows or financial position. In addition, regardless of the outcome, litigation could have an adverse impact on us because of attorneys' fees and costs, diversion of management resources and other factors.

Segment Reporting [Abstract]

Segment and Geographic Information

Operating segments are defined as components of an enterprise that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and to assess performance. Our chief operating decision maker is our President and Chief Executive Officer.

We have two operating and reportable segments, which are consistent with our reporting units: i) subscription and software and ii) services. The subscription and software segment is engaged in the licensing of process optimization software solutions and associated support services. The services segment includes professional services and training.

The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies (refer to Note 2). We do not track assets or capital expenditures by operating segments. Consequently, it is not practical to present assets, capital expenditures, depreciation or amortization by operating segments.

The following table presents a summary of our reportable segments' profits:
