NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

June 30, 2013

Note 1 — Basis for Presentation

Cubic Corporation (“we”, “us”, and “Cubic”) has prepared the accompanying unaudited condensed consolidated financial statements in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

In our opinion, all adjustments necessary for a fair presentation of these financial statements have been included, and are of a normal and recurring nature. Operating results for the three- and nine- month periods ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ending September 30, 2013. For further information, refer to the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended September 30, 2012.

The preparation of the financial statements in conformity with GAAP requires us to make estimates and assumptions that 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 revenues and expenses during the reporting period. Actual results could differ from those estimates.

There have been no material changes to our significant accounting policies as compared with the significant accounting policies described in the Annual Report on Form 10-K for the fiscal year ended September 30, 2012, other than the revisions to or addition of the following:

Revenue recognition.

We generate revenue from the sale of products such as mass transit fare collection systems, air and ground combat training systems, and secure communications products. We also generate revenue from services we provide such as specialized military training exercises, including live, virtual and constructive training exercises and support, and we operate and maintain fare systems for mass transit customers. We classify sales as products or services in our Consolidated Statements of Income based on the attributes of the underlying contracts.

We recognize sales and profits under our long-term fixed-price contracts, which generally require a significant amount of development effort in relation to total contract value, using the cost-to-cost percentage-of-completion method of accounting. We record sales and profits based on the ratio of contract costs incurred to estimated total contract costs at completion. Contract costs include material, labor and subcontracting costs, as well as an allocation of indirect costs. For contracts with the U.S. federal government, general and administrative costs are included in contract costs; however, general and administrative costs are not considered contract costs for any other customers. Costs are recognized as incurred for contracts accounted for under the cost-to-cost percentage-of-completion method.

For certain other long-term, fixed price production contracts not requiring substantial development effort we use the units-of-delivery percentage-of-completion method as the basis to measure progress toward completing the contract and recognizing sales. The units-of delivery measure recognizes revenues as deliveries are made to the customer generally using unit sales values in accordance with the contract terms. Costs of sales are recorded as deliveries are made. We estimate profit as the difference between total estimated revenue and total estimated cost of a contract and recognize that profit over the life of the contract based on deliveries.

For long-term fixed price contracts, we only include amounts representing contract change orders, claims or other items in the contract value when they can be reliably estimated and we consider realization probable. Changes in estimates of sales, costs and profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current and prior periods. A significant change in one or more of these estimates could have a material effect on our consolidated financial position or results of operations.

We record sales under cost-reimbursement-type contracts as we incur the costs. The Federal Acquisition Regulations provide guidance on the types of costs that we will be reimbursed in establishing the contract price. We consider incentives or penalties and awards applicable to performance on contracts in estimating sales and profits, and record them when there is sufficient information to assess anticipated contract performance. We do not recognize incentive provisions that increase or decrease earnings based solely on a single significant event until the event occurs.

Table of Contents

We occasionally enter into contracts that include multiple deliverables such as the construction or upgrade of a system and subsequent services to operate and maintain the delivered system. For multiple element contracts that were entered prior to October 1, 2009, a delivered item was considered a separate unit of accounting when it had value to the customer on a standalone basis and there was objective and reliable evidence of the fair value of the undelivered items. For contracts where we are unable to conclude there were separate units of accounting, we combine the deliverables and recognize revenue once the final item has been delivered or, if the final element is a service, over the period of performance.

We elected to adopt authoritative accounting guidance for multiple-element arrangements effective October 1, 2009 on a prospective basis. This guidance affected the accounting conclusion as to whether a deliverable under a contract is considered a separate unit of accounting, and also affected the method that is used to allocate arrangement consideration to each separate unit of accounting. The new guidance eliminates the requirement for objective and reliable evidence of fair value to exist for the undelivered items in order for a delivered item to be treated as a separate unit of accounting. The new guidance also requires arrangement consideration to be allocated at the inception of the arrangement to all deliverables using the relative-selling-price method and eliminates the use of the residual method of allocation. Under the relative-selling-price method, the selling price for each deliverable is determined using vendor specific objective evidence (VSOE) of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling price exists for a deliverable, which is typically the case for our contracts, the guidance requires us to determine the best estimate of the selling price, which is the price at which we would sell the deliverable if it were sold on a standalone basis. In estimating the selling price of the deliverable on a standalone basis, we consider our overall pricing models and objectives, including the factors we contemplate in negotiating our contracts with our customers. The pricing models and objectives that we use are generally based upon a cost-plus margin approach, with the estimated margin based in part on qualitative factors such as perceived customer pricing sensitivity and competitive pressures.

Once the contract value is allocated to the separate deliverables under a multiple-element arrangement, revenue recognition guidance relevant to each contractual element is followed. For example, for the long-term construction portion of a contract we use the percentage-of completion method and for the services portion we recognize the service revenues on a straight-line basis over the contractual service period or based on measurable units of work performed or incentives earned. Revenue under our service contracts with the U.S. government is recorded under the cost-to cost percentage-of-completion method. Award fees and incentives related to performance under these service contracts are accrued during the performance of the contract based on our historical experience and estimates of success with such awards.

Revenue under contracts for services other than those with the U.S. government and those associated with design, development, or production activities is recognized either as services are performed or when a contractually required event has occurred, depending on the contract. For such contracts that contain measurable units of work performed we recognize sales when the units of work are completed. Certain of our transportation systems service contracts contain service level or system usage incentives, for which we recognize revenues when the incentive award is fixed or determinable. These contract incentives are generally based upon monthly service levels or monthly performance and become fixed or determinable on a monthly basis. However, one of our transportation systems service contracts contains annual system usage incentives which are based upon system usage compared to annual baseline amounts. For this contract the annual system usage incentives are not considered fixed or determinable until the end of the contract year for which the incentives are measured, which falls within the second quarter of our fiscal year. Revenue under such contracts that do not contain measurable units of work performed, which is generally the case for our service contracts, is recognized on a straight-line basis over the contractual service period, unless evidence suggests that the revenue is earned, or obligations fulfilled, in a different manner. Costs incurred under these services contracts are expensed as incurred.

We make provisions in the current period to fully recognize any anticipated losses on contracts. If we receive cash on a contract prior to revenue recognition or in excess of inventoried costs, we classify it as a customer advance on the balance sheet.

Recognizing assets acquired and liabilities assumed in business combinations.

Acquired assets and assumed liabilities are recognized in a business combination on the basis of their fair values at the date of acquisition. We assess fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, using a variety of methods including income approaches such as present value techniques or cost approaches such as the estimation of current selling prices and replacement values. Fair value of the assets acquired and liabilities assumed, including intangible assets, and contingent payments, are measured based on the assumptions and estimations with regards to the variable factors such as the amount and timing of future cash flows for the asset or liability being measured, appropriate risk-adjusted discount rates, nonperformance risk, or other factors that market participants would consider. Upon acquisition, we determine the estimated economic lives of the acquired intangible assets for amortization purposes, which are based on the underlying expected cash flows of such assets. Adjustments to inventory are based on the fair market value of inventory and amortized into income based on the period in which the underlying inventory is sold. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Actual results may vary from projected results and assumptions used in the fair value assessments.

Stock-Based Compensation

Restricted stock units awards (RSUs) are granted to eligible employees and directors and represent rights to receive shares of common stock at a future date if vesting occurs. RSUs granted to date have either time-based vesting or performance-based vesting. Compensation expense for all restricted stock unit awards is measured at fair value at the grant date and recognized based upon the number of RSUs that ultimately vest. We determine the fair value of RSUs based on the closing market price of our common stock on the grant date. The grant date of the performance-based RSUs takes place when the grant is authorized and the specific achievement goals are communicated.

Compensation expense for time-based vesting awards is recorded on a straight-line basis over the requisite service period, adjusted by estimated forfeiture rates. Vesting of performance-based RSUs is tied to achievement of specific company goals over the measurement period. For all performance-based RSUs granted to date, the measurement period is October 1, 2012 through September 30, 2015. For purposes of measuring compensation expense for performance-based RSUs, at each reporting date we estimate the number of shares for which vesting is deemed probable based on management’s expectations regarding achievement of the relevant performance criteria, adjusted by estimated forfeiture rates. Compensation expense for the number of shares ultimately expected to vest is recognized on a straight-line basis over the requisite service period for the performance-based RSUs. The recognition of compensation expense associated with performance-based RSUs requires judgment in assessing the probability of meeting the performance goals. For performance-based RSUs, there may be significant expense recognition or reversal of recognized expense in periods in which there are changes in the assessed probability of meeting performance-based vesting criteria.

Net Income Per Share

Basic net income per share (EPS) is computed by dividing the net income for the period by the weighted average number of common shares outstanding during the period, including vested RSUs.

Diluted EPS is computed by dividing the net income for the period by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of dilutive restricted stock units. Dilutive restricted stock units are calculated based on the average share price for each fiscal period using the treasury stock method. For RSUs with performance-based vesting, no common equivalent shares are included in the computation of diluted EPS until the related performance criteria have been met. Basic and diluted EPS are computed as follows (amounts in thousands, except per share data).

Note 2 — Acquisitions

NEK

On December 14, 2012, Cubic acquired from NEK Advanced Securities Group, Inc. (Seller) the customer contracts and operating assets of NEK Special Programs Group LLC (NEK), which consists of the Seller’s Special Operation Forces training business based in Fayetteville, North Carolina and Colorado Springs, Colorado. This acquisition will expand the scope of services and customer base of our Mission Support Services (MSS) segment. In connection with the acquisition, we hired more than 200 employees of the Seller’s Special Operations Forces training business. This transaction has been accounted for as a business combination. The results of the acquired operations have been included in our condensed consolidated financial statements since the acquisition date. For the three months ended June 30, 2013 the amount of NEK’s net sales and net loss after taxes included in our consolidated statement of income were $11.4 million and $0.5 million, respectively. For the nine months ended June 30, 2013 the amounts of NEK’s net sales and net loss after taxes were $21.1 million and $0.8 million respectively. Included in the NEK operating results are $0.6 million in transaction related costs incurred during the nine months ended June 30, 2013.

The acquisition agreement states that the cost of the acquisition will total $52.0 million, adjusted by the difference between the net working capital acquired and targeted working capital amounts, less amounts that will not be due if certain future events fail to occur. The acquisition-date fair value of consideration transferred is estimated to be $52.6 million. In December 2012, we paid the Seller cash consideration of $33.1 million and we recorded a current liability of approximately $19.5 million as an estimate of additional cash consideration that was due to the Seller. In the third quarter of fiscal 2013 we paid the Seller $7.4 million of this additional cash consideration. At June 30, 2013 our remaining liability for the estimated additional cash consideration due to the Seller is $12.1 million. The timing of the payment of $1.0 million of the additional cash consideration will be accelerated if the Seller causes certain events to occur, but will ultimately be paid over the passage of time regardless of whether these events occur. Approximately $11.1 million of the additional cash consideration is contingent upon future events, including the novation of certain of the Seller’s contracts to NEK. We have estimated the fair value of the contingent consideration using a probability-weighted discounted cash flow model. We have estimated that the probability of payment of any amounts less than the maximum possible additional cash consideration of $11.1 million is remote, and we have estimated that the contingent consideration amounts will be paid within six to nine months of the acquisition date. As such, we have estimated that the fair value of the additional cash consideration at June 30, 2013 approximates the maximum possible contingent payments to the Seller of $11.1 million. There has been no change in the estimated fair value of the total estimated contingent payments to be made to the Seller since the date of the acquisition.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):

The estimated fair value of the accounts receivable and accounts payable will be finalized as further information is received from the Seller regarding these items.

The preliminary estimated fair values of purchased intangibles were determined using the valuation methodology deemed to be the most appropriate for each type of asset being valued. Each of the valuation methodologies used were various methods under the income approach. The trade names valuation used the relief from royalty approach. The customer relationships valuation used the excess earnings approach and the non-compete agreements valuation used the with and without approach. The intangible assets will be amortized using a combination of straight-line and accelerated methods based on the expected cash flows from the assets, over a weighted average useful life of four years from the date of acquisition.

The goodwill resulting from the acquisition consists primarily of the synergies expected from combining the operations of NEK and our MSS business and the acquired assembled workforce. The anticipated synergies include the ability to expand services offerings and cost reductions. The amount recorded as goodwill is allocated to our MSS segment and is expected to be deductible for tax purposes.

Based upon the preliminary estimate of the fair value of identifiable intangible assets, the estimated amortization expense related to the intangible assets recorded in connection with our acquisition of NEK for fiscal years 2013 through 2017 is as follows (in millions):

NextBus

On January 24, 2013, Cubic acquired all of the outstanding capital stock of NextBus, Inc. (NextBus) from Webtech Wireless, Inc. (Webtech). NextBus provides products and services to transit agencies which provide real-time passenger information to transit passengers, expanding the portfolio of services and customer base of our Cubic Transportation Systems (CTS) segment. This transaction has been accounted for as a business combination. The results of the acquired NextBus operations have been included in our condensed consolidated financial statements since the acquisition date. For the three months ended June 30, 2013 the amount of NextBus’ net sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $3.1 million and $0.1 million, respectively. For the nine months ended June 30, 2013 the amounts of NextBus’ net sales and net loss after taxes were $4.6 million and $0.3 million respectively. Included in the NextBus operating results are $0.2 million in transaction related costs incurred during the nine months ended June 30, 2013.

The purchase agreement states that the cost of the acquisition will total $20.7 million, adjusted by the difference between the net working capital acquired and targeted working capital amounts. The acquisition-date fair value of consideration transferred is estimated to be $20.2 million. In January 2013, we paid cash of $20.7 million and recorded a current asset of approximately $0.7 million as an estimate of the cash that will be received from Webtech in connection with the working capital settlement. In our third fiscal quarter of 2013 we adjusted the estimated working capital settlement receivable to $0.4 million and received this settlement amount.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):

The estimated fair values of the assets acquired and liabilities assumed, including the fair value of purchased intangibles, and net deferred tax liabilities are preliminary estimates pending the finalization of our valuation analyses. The net deferred tax liabilities were primarily recorded to reflect the tax impact of the identified intangible assets that will not generate tax deductible amortization expense.

The preliminary estimated fair values of purchased intangibles were determined using the valuation methodology deemed to be the most appropriate for each type of asset being valued. Each of the valuation methodologies used were various methods under the income approach. The customer relationships and backlog valuations used the excess earnings approach. The trade names and technology valuations used the relief from royalty approach.

The goodwill resulting from the acquisition consists primarily of the synergies expected from combining the operations of NextBus and our CTS business and the acquired assembled workforce. The anticipated synergies include the ability to expand services offerings and cost reductions. The amount recorded as goodwill is allocated to our CTS segment and is not expected to be deductible for tax purposes.

The intangible assets will be amortized using a combination of accelerated and straight-line based on the expected cash flows from the assets, over a weighted average useful life of 5 years from the date of acquisition. Based upon the preliminary estimate of the fair value of identifiable intangible assets, the estimated amortization expense related to the intangible assets recorded in connection with our acquisition of NextBus for fiscal years 2013 through 2017 is as follows (in millions):

The following unaudited pro forma information presents our consolidated results of operations as if NextBus and NEK had been included in our consolidated results since October 1, 2011 (in millions):

The pro forma information includes adjustments to give effect to pro forma events that are directly attributable to the acquisitions and have a continuing impact including the amortization of purchased intangibles and the elimination of interest expense for the repayment of debt. No adjustments were made for transaction expenses, other adjustments that do not reflect ongoing operations or for operating efficiencies or synergies. The pro forma financial information is not necessarily indicative of what the consolidated financial results of our operations would have been had the acquisitions been completed on October 1, 2011, and it does not purport to project our future operating results.

Note 3 — Balance Sheet Details

Marketable securities consist of exchange traded funds whose underlying assets consist of highly liquid debt instruments with short-term maturities. Marketable securities are classified and accounted for as available-for-sale.  These investments are recorded at fair value in the accompanying Condensed Consolidated Balance Sheets and the change in fair value is recorded, net of taxes, as a component of other comprehensive income. There have been no significant realized or unrealized gains or losses on these marketable securities to date. Marketable securities have been classified as current assets in the accompanying Condensed Consolidated Balance Sheets based upon the nature of the securities and availability for use in current operations.

The components of accounts receivable are as follows (in thousands):

The amount classified as not currently due is an estimate of the amount of long-term contract accounts receivable that will not be collected within one year from June 30, 2013 under transportation systems contracts in the U.S. and Australia based upon the payment terms in the contracts. The non-current balance at September 30, 2012 represented non-current amounts due from customers under transportation systems contracts in the same locations.

Table of Contents

Inventories consist of the following (in thousands):

Pursuant to contract provisions, agencies of the U.S. government and certain other customers have title to, or security interest in, inventories related to such contracts as a result of advances, performance-based payments, and progress payments. Contract advances, performance-based payments and progress payments received are recorded as an offset against the related inventory balances for contracts that that are accounted for on a percentage-of-completion basis using units-of-delivery as the basis to measure progress toward completing the contract. This determination is performed on a contract by contract basis. Any amount of payments received in excess of the cumulative amount of accounts receivable and inventoried costs for a contract is classified as advanced payments, which is classified as a liability on the balance sheet.

At June 30, 2013, work in process and inventoried costs under long-term contracts includes approximately $2.5 million in costs incurred outside the scope of work or in advance of a contract award compared to $1.9 million at September 30, 2012. We believe it is probable that we will recover these costs, plus a profit margin, under contract change orders or awards within the next year.

Long-term capitalized contract costs include costs incurred on a contract to develop and implement a transportation fare system for a customer for which revenue will not begin to be recognized until the system has been delivered.

Note 4 — Fair Value of Financial Instruments

We carry financial instruments including cash equivalents, accounts receivable, short-term borrowings, accounts payable and accrued liabilities at cost, which we believe approximates fair value because of the short-term maturity of these instruments. Receivables consist primarily of amounts due from U.S. and foreign governments for defense products and local government agencies for transportation systems. Due to the nature of our customers, we generally do not require collateral. We have limited exposure to credit risk as we have historically collected substantially all of our receivables from government agencies.

The valuation techniques required for fair value accounting are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. The two types of inputs create the following fair value hierarchy:

·                  Level 1 - Quoted prices for identical instruments in active markets.

·                  Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

·                  Level 3 - Significant inputs to the valuation model are unobservable.

The following table presents assets and liabilities measured and recorded at fair value on our Condensed Consolidated Balance Sheets on a recurring basis (in thousands). The fair value of cash equivalents approximates their cost. Derivative financial instruments related to foreign currency forward contracts are measured at fair value, the material portions of which are based on active or inactive markets for identical or similar instruments or model-derived valuations whose inputs are observable. Where model-derived valuations are appropriate, we use the applicable credit spread as the discount rate. Credit risk related to derivative financial instruments is considered minimal and is managed by requiring high credit standards for counterparties and through periodic settlements of positions.

Table of Contents

The fair value of our contingent consideration obligation to the Seller of NEK is revalued to its fair value each period and any recorded increase or decreases is recorded into selling, general and administrative expense. Any changes in the assumed timing and amount of the probability of payment scenarios could impact the fair value. We have estimated the fair value of the contingent consideration using a probability-weighted discounted cash flow model. We have estimated that the probability of payment of any amounts less than the maximum possible additional cash consideration of $11.1 million is remote, and we have estimated that the contingent consideration amounts will be due within six to nine months of the acquisition date. As such, we have estimated that the fair value of the additional cash consideration approximates the maximum possible contingent payments to the Seller of $11.1 million. There was no change in the fair value of the contingent consideration between the date of the acquisition of NEK and June 30, 2013; therefore, there has been no change in contingent consideration recorded in operations. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and each subsequent period. Accordingly, changes in the assumptions described above can materially impact the amount of contingent consideration expense we record in any period.

Long-term debt and short-term borrowings are carried at amortized cost. The fair values of long-term debt and short-term borrowings are calculated by discounting the value of the note based on market interest rates for similar debt instruments, which is a Level 2 valuation technique. At June 30, 2013, the fair value of our long-term debt was estimated to be approximately $96.6 million compared to a carrying value of $102.9 million. At September 30, 2012, the fair value of our long-term debt was estimated to be approximately $12.5 million compared to a carrying value of $11.5 million.

Note 5 — Financing Arrangements

We have a committed revolving credit agreement with a group of financial institutions in the amount of $200.0 million, expiring in May 2017 (Revolving Credit Agreement). The available line of credit on the Revolving Credit Agreement is reduced by any letters of credit issued under the agreement. As of June 30, 2013, there were no borrowings outstanding under this agreement. Any borrowings under the Revolving Credit Agreement bear interest at a variable rate. There were letters of credit outstanding under the Revolving Credit Agreement totaling $36.1 million at June 30, 2013, which reduce the available line of credit to $163.9 million.

We have a secured letter of credit facility agreement with a bank (Secured Letter of Credit Facility) which expires in March 2014. At June 30, 2013, there were letters of credit outstanding under this agreement of $55.1 million. In support of the Secured Letter of Credit Facility, we have $68.9 million of our cash on deposit in the U.K. as collateral in a restricted account with the bank providing the facility. We are required to leave the cash in the restricted account so long as the bank continues to maintain associated letters of credit under the facility. The maximum amount of letters of credit currently allowed by the facility is $62.6 million, and any increase above this amount would require bank approval and additional restricted funds to be placed on deposit. We may choose at any time to terminate the facility and move the associated letters of credit to another credit facility. Letters of credit outstanding under the Secured Letter of Credit Facility do not reduce the available line of credit available under the Revolving Credit Agreement.

On March 12, 2013, we entered into a note purchase and private shelf agreement pursuant to which we agreed to issue $100.0 million of senior unsecured notes, bearing interest at a rate of 3.35% and maturing on March 12, 2025. Notes with an aggregate principal amount of $50.0 million were purchased on March 12, 2013 and notes with the remaining aggregate principal amount of $50.0 million were purchased on April 23, 2013. In addition, pursuant to the agreement, we may from time to time issue and sell, and the purchasers may in their sole discretion purchase, within the next three years, additional senior notes in aggregate principal amount of up to $25.0 million that will have terms, including interest rate, as we and the purchasers may agree upon at the time of issuance.

Note 6 — Pension Plans

The components of net periodic pension cost (benefit) are as follows (in thousands):

Note 7 - Stockholders’ Equity

Long Term Equity Incentive Plan

On March 21, 2013, the Executive Compensation Committee of the Board of Directors approved a long-term equity incentive award program and awarded 264,549 RSUs with time-based vesting and 161,962 RSUs with performance-based vesting to certain officers, directors and management. Each RSU represents a contingent right to receive one share of our common stock. Dividend equivalent rights accrue with respect to the RSUs when and as dividends are paid on our common stock and vest proportionately with the RSUs to which they relate. Vested shares will be delivered to the recipient following each vesting date.

The RSUs with time-based vesting will vest in four equal installments on each of October 1, 2013, 2014, 2015 and 2016, subject to the recipient’s continued service through such date.

16

Table of Contents

The performance period for the performance-based vesting RSUs granted on March 21, 2013 is the period from October 1, 2012 to September 30, 2015. Recipients of the performance-based vesting RSUs will be eligible to vest in the RSUs at the end of the three-year performance period based on Cubic’s achievement of performance goals established by the Executive Compensation Committee over the performance period, subject to the recipient’s continued service through September 30, 2015. The vesting of 50% of the performance-based RSUs is contingent upon Cubic meeting specified sales growth targets during the performance period and vesting of 50% of the performance based RSUs is contingent upon Cubic meeting return on equity targets for the performance period. Cubic’s sales growth achievement and/or return on equity achievement for the performance period will determine the percentage of the RSUs that will vest.

Through June 30, 2013, Cubic has granted 426,511 restricted stock units of which none have vested. The restricted stock units have a weighted-average grant date fair value of $43.76 per share, which represents the fair market value of one share of our common stock at the grant date. At June 30, 2013, the total number of RSUs that are ultimately expected to vest, after consideration of expected forfeitures and estimated vesting of performance-based RSUs is 231,801.

The following table summarizes our RSU activity for 2013:

Note 8 - Stock-Based Compensation

Compensation expense related to stock-based awards was $1.6 million for the three- and nine-month periods ended June 30, 2013. Total stock-based compensation expense related to all of our RSUs was comprised of the following (in thousands):

As of June 30, 2013, there was $16.8 million of unrecognized compensation cost related to unvested RSUs. This amount is expected to be recognized over a weighted-average period of 1.5 years. Based upon the expected forfeitures and the expected vesting of performance based RSUs, the aggregate fair value of RSUs expected to ultimately vest is $10.1 million.

We are required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods on a cumulative basis in the period the estimated forfeiture rate changes for all stock-based awards when significant events occur. We consider our historical experience with employee turnover as the basis to arrive at our estimated forfeiture rate. The forfeiture rate was estimated to be 12.5% per annum as of June 30, 2013. To the extent the actual forfeiture rate is different from what we have estimated, stock-based compensation related to these awards will be different from our expectations.

Note 9 — Income Taxes

Our effective tax rate for the nine months ended June 30, 2013 is lower than the U.S. federal statutory tax rate primarily due to the amount of income earned in foreign tax jurisdictions that is taxed at lower rates than the U.S. federal statutory tax rate and reinstatement of the U.S. federal research and development tax credit included in the American Taxpayer Relief Act of 2012, which was signed into law on January 2, 2013.

Our effective tax rate for the nine months ended June 30, 2013 was 25% as compared to 29% for the year ended September 30, 2012. The effective tax rate for the nine months ended June 30, 2013 benefitted from the retroactive extension of the federal research and development tax credit.

The amount of unrecognized tax benefits was $9.1 million as of June 30, 2013 and $8.3 million as of September 30, 2012, exclusive of interest and penalties. At June 30, 2013, the amount of unrecognized tax benefits from permanent tax adjustments that, if recognized, would favorably impact the effective rate was $6.9 million. During the next 12 months, it is reasonably possible that resolution of reviews by taxing authorities, both domestic and international, could be reached with respect to approximately $4.9 million of the unrecognized tax benefits depending on the timing of examinations and expiration of statute of limitations, either because our tax positions are sustained or because we agree to their disallowance and pay the related income tax.

We are subject to ongoing audits from various taxing authorities in the jurisdictions in which we do business. As of June 30, 2013, the tax years open under the statute of limitations in significant jurisdictions include fiscal years 2008-2012 in the U.K., 2008-2012 in New Zealand and 2009-2012 in the U.S. We have effectively settled all tax matters with the IRS for fiscal years prior to fiscal year 2011. We believe we have adequately provided for uncertain tax issues that have not yet resolved with federal, state and foreign tax authorities.

Note 10 — Derivative Instruments and Hedging Activities

In order to manage our exposure to fluctuations in interest and foreign currency exchange rates we utilize derivative financial instruments such as forward starting swaps and foreign currency forwards. We do not use any derivative financial instruments for trading or other speculative purposes.

All derivatives are recorded at fair value, however, the classification of gains and losses resulting from changes in the fair values of derivatives are dependent on the intended use of the derivative and its resulting designation. If a derivative is designated as a fair value hedge, then a change in the fair value of the derivative is offset against the change in the fair value of the underlying hedged item and only the ineffective portion of the hedge, if any, is recognized in earnings. If a derivative is designated as a cash flow hedge, then the effective portion of a change in the fair value of the derivative is recognized as a component of accumulated other comprehensive income until the underlying hedged item is recognized in earnings, or the forecasted transaction is no longer probable of occurring. If a derivative does not qualify as a highly effective hedge, any change in fair value is immediately recognized in earnings. We formally document all hedging relationships for all derivative hedges and the underlying hedged items, as well as the risk management objectives and strategies for undertaking the hedge transactions. We classify the fair value of all derivative contracts as current or non-current assets or liabilities, depending on the realized and unrealized gain or loss position of the hedged contract at the balance sheet date, and the timing of future cash flows. The cash flows from derivatives treated as hedges are classified in the Condensed Consolidated Statements of Cash Flows in the same category as the item being hedged.
