	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 as well as all adjustments discussed in Note 2, “Restatement of Condensed Consolidated Financial Statements,” considered necessary to fairly state the financial position of Cubic Corporation at December 31, 2013 and September 30, 2013; the results of its operations for the three-month periods ended December 31, 2013 and 2012; and its cash flows for the three-month periods ended December 31, 2013 and 2012. Operating results for the three-month periods ended December 31, 2013 are not necessarily indicative of the results that may be expected for the year ending September 30, 2014. For further information, refer to the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K/A for the year ended September 30, 2013 filed concurrently herewith.
	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 our Annual Report on Form 10-K/A for the year ended September 30, 2013 filed concurrently herewith.

	Note 2—Restatement of Condensed Consolidated Financial Statements
	We have restated our Condensed Consolidated Balance Sheet at September 30, 2013 and our Condensed Consolidated Statements of Income, Comprehensive Income, and Cash Flows for the three-month period ended December 31, 2012.
	The cumulative adjustments to correct the errors in the consolidated financial statements for all periods prior to October 1, 2012 are recorded as adjustments to retained earnings and accumulated other comprehensive income (loss) at September 30, 2012. The cumulative effect of those adjustments increased previously reported retained earnings by $6.3 million and reduced previously reported accumulated other comprehensive loss by $0.5 million at September 30, 2012.
	The following tables present the summary impacts of the restatement adjustments on our previously reported consolidated retained earnings at September 30, 2012 and consolidated net income for the three months ended December 31, 2012 (in thousands):
	Retained earnings at September 30, 2012 - As previously reported	$	715,043

	Description of Adjustments
	On February 10, 2014, we announced that we would be restating certain previously issued audited consolidated financial statements and unaudited condensed consolidated financial statements primarily to correct two errors in the recognition of revenue.
	In 2012, we restated our financial statements for the years ended September 30, 2011, 2010 and 2009, the quarters ended March 31, 2012 and December 31, 2011 and each of the prior quarters of 2011 and 2010. This previous restatement was the result of our determination that we had made errors in the calculation of revenues for a significant number of our contracts due to incorrect application of GAAP. In the course of our financial statement closing process for the quarter ended December 31, 2013, we identified two errors related to revenue recognition for two contracts with the same customer that date back to the previous restatement period. The first error was related to the computation of revenues for a contract that was entered in 2011. The error resulted from a miscalculation in a revenue recognition model that was created during the previous restatement activity. The second error relates to a contract entered into in 2007 and was the result of a failure to appropriately update the contract value in our revenue accounting system as well as a failure to properly account for a 2008 amendment to this contract. Upon modification of this second contract in 2008, the cost-to-cost percentage of completion method should no longer have been used, and revenue should have been recognized using a service-based model.
	In addition to the errors described above, we also made adjustments related to other individually immaterial errors including certain corrections that had been previously identified but not recorded because they were not material, individually or in the aggregate, to our consolidated financial statements. These corrections included certain accrued liabilities and reserves and miscellaneous reclassification entries; adjustments to various income tax and indirect tax accrual accounts; and adjustments to sales and cost of sales to correct cutoff on immaterial revenue recognition transactions.
	The following tables present the impact of the restatement on the our previously issued condensed consolidated balance sheet as of September 30, 2013, and our Consolidated Statements of Income, Comprehensive Income and Cash Flows for the three months ended December 31, 2012:

Acquisitions	'
	Note 3 — Acquisitions
	Each of the following acquisitions has been treated as a business combination for accounting purposes. The results of operations of each acquired business has been included in our consolidated financial statements since the respective date of each acquisition.
	ITMS
	On November 26, 2013 we acquired all of the outstanding capital stock of Intelligent Transport Management Solutions Limited (ITMS) from Serco Limited. ITMS is a provider of traffic management systems technology, traffic and road enforcement and maintenance of traffic signals, emergency equipment and other critical road and tunnel infrastructure. The acquisition of ITMS expands the portfolio of services and customer base of our Cubic Transportation Systems (CTS) segment.
	For the three months ended December 31, 2013, the amount of ITMS’ sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $4.7 million and $0.5 million, respectively. Included in the ITMS operating results are $0.4 million of transaction costs incurred during the three months ended December 31, 2013.
	The purchase agreement states that the cost of the acquisition was approximately $69.0 million, adjusted by the difference between the net working capital acquired and the targeted working capital amounts. The acquisition date fair value of the consideration transferred is estimated to be $72.3 million. In November 2013, we paid cash of approximately $69.0 million and have recorded a liability of approximately $3.3 million as an estimate of the cash that will be paid to the seller in connection with the working capital settlement.
	The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):
	Customer relationships	$	15.7
	Intellectual property	1.6
	Backlog	5.7
	Supplier relationships	0.6
	Agreements with Seller	1.3
	Accounts receivable - billed	4.4
	Accounts receivable - unbilled	6.9
	Deferred tax liabilities, net	(0.2		)
	Deferred revenue	(2.4		)
	Accounts payable and accrued expenses	(4.6		)
	Other net assets acquired	2.6
	Net identifiable assets acquired	31.6
	Goodwill	40.7
	Net assets acquired	$	72.3
	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 estimated fair value of the accounts receivable and accounts payable and accrued expenses will be finalized as further information is received from the seller regarding these items.
	The fair values of purchased intangibles were determined using the valuation methodology deemed to be the most appropriate for each type of asset being valued.
	The customer relationships and backlog valuation used the excess earnings approach and the non-compete agreement and seller agreements valuations used the with and without approach. The supplier relationship and intellectual property valuations used the replacement cost 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 two years from the date of acquisition and is not expected to be deductible for tax purposes.
	The goodwill resulting from the acquisition consists primarily of the synergies expected from combining the operations of ITMS with our existing 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.
	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 ITMS for fiscal years 2014 through 2018 is as follows (in millions):
	Year Ended
	September 30,
	2014	$	7.3
	2015	6.8
	2016	5.3
	2017	3.9
	2018	1.9
	NEK
	On December 14, 2012, we 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. For the three months ended December 31, 2013, the amounts of NEK’s sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $10.7 million and $0.1 million, respectively. For the three months ended December 31, 2012, the amounts of NEK’s sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $0.5 million and $0.1 million, respectively. Included in the NEK operating results are $0.4 million in transaction related costs.
	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. Through December 31, 2013 we have paid the Seller cash consideration of $49.1 million from our existing cash resources and we have recorded a current liability of approximately $3.5 million at December 31, 2013 as an estimate of additional cash consideration that is due to the Seller. The timing of the payment of $0.7 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 $2.8 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 our payment to the Seller of any amounts less than the maximum possible additional cash consideration of $2.8 million is remote. As such, we have estimated that the fair value of the additional cash consideration at December 31, 2013 approximates the maximum possible contingent payments to the Seller of $2.8 million. There has been no significant 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 fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):
	Customer relationships	$	13.3
	Corporate trade names	4.9
	Non-compete agreements	0.2
	Accounts receivable -billed	3.1
	Accounts receivable -unbilled	7.7
	Accounts payable	(3.0		)
	Other net liabilities assumed	(0.4		)
	Net identifiable assets acquired	25.8
	Goodwill	26.8
	Net assets acquired	$	52.6
	The 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 are being 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 Mission Support Services (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 fair value of identifiable intangible assets, the amortization expense related to the intangible assets recorded in connection with our acquisition of NEK for fiscal years 2014 through 2018 is as follows (in millions):
	Year Ended September 30,

	NextBus
	On January 24, 2013, we acquired all of the outstanding capital stock of NextBus, Inc. (NextBus) from Webtech Wireless, Inc. 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 CTS segment. For the three months ended December 31, 2013 the amount of NextBus’ sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $2.2 million and $0.4 million, respectively.
	We paid the seller cash of $20.2 million for NextBus from our existing cash resources. The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):
	Customer relationships	$	8.8
	Accounts receivable, net	2.2
	Backlog	1.7
Acquired technology	1.3
Corporate trade names	1
Accounts payable and accrued expenses	(1.1		)
Deferred tax liabilities, net	(3.3		)
Other net liabilities assumed	(1.2		)
Net identifiable assets acquired	9.4
Goodwill	10.8
Net assets acquired	$	20.2
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 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 are being 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 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 2014 through 2018 is as follows (in millions):
Year Ended September 30,

AIS
On July 1, 2013 we acquired certain assets of Advanced Interactive Systems (AIS) and all of the capital stock of its foreign subsidiaries through a bankruptcy auction. AIS is a supplier of live fire specialized range facilities, virtual simulation products, engineering design and project management services for counter-terrorism, law enforcement and military forces worldwide. For the three months ended December 31, 2013 the amount of AIS’ sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $1.3 million and $0.3 million, respectively.
We paid cash of $2.0 million from our existing cash resources, net of cash acquired, for the assets of AIS. At September 30, 2013, the estimated fair value of liabilities for potential claims from customers were preliminary estimates pending the finalization of our valuation analyses. The finalization of the estimation of these values was completed in the quarter ended December 31, 2013 as further information was received from the customers as to the facts and circumstances that existed as of the July 1, 2013 acquisition date. As a result of this additional information, we have estimated that the fair value of the potential customer claims was $1.3 million. As a result, the carrying amount of the potential customer claims liabilities was retrospectively increased by $1.3 million on July 1, 2013, due to this new information, with a corresponding increase to goodwill.
The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date (in millions) including the retrospective adjustments described above:
Customer relationships	$	1.4
Technology	0.9
Backlog	0.6
Other net liabilities assumed	(2.8		)
Net identifiable assets acquired	0.1
Goodwill	1.9
Net assets acquired	$	2
The amount recorded as goodwill is allocated to our Cubic Defense Systems (CDS) segment and is not expected to be deductible for tax purposes.
PSMC
On July 1, 2013 we acquired certain assets of PS Management Consultants Pty Ltd. (PSMC). PSMC is a specialist project management and engineering enterprise, based in Canberra, Australia. For the three months ended December 31, 2013 the amount of PSMC’s sales and net income after taxes included in our Condensed Consolidated Statement of Income were $0.7 million and $0.2 million, respectively.
We paid cash of $1.3 million from our existing cash resources to acquire PSMC. The following table summarizes the estimated fair values of the assets acquired at the acquisition date (in millions):
Customer relationships	$	0.6
Backlog	0.1
Net identifiable assets acquired	0.7
Goodwill	0.6
Net assets acquired	$	1.3
The goodwill resulting from the acquisition consists primarily of the synergies expected from combining the operations of PSMC and our CDS 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 CDS segment and is not expected to be deductible for tax purposes.
Changes in goodwill for the three months ended December 31, 2013 were as follows (in millions):

	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 restricted stock units (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.

	Note 5 — Balance Sheet Details
	Marketable Securities
	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.
	Accounts Receivable
	The components of accounts receivable are as follows (in thousands):
		December 31,			September 30,
		2013			2013
					(As Restated)
	Trade and other receivables	$	23,346		$	17,352

	Less estimated amounts not currently due	(18,142		)	(19,021		)
	Current accounts receivable	$	405,434		$	379,002
	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 December 31, 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, 2013 represented non-current amounts due from customers under transportation systems contracts in the same locations.
	Inventories
	Inventories consist of the following (in thousands):
		December 31,			September 30,
		2013			2013
					(As Restated)
	Work in process and inventoried costs under long-term contracts	$	96,708		$	80,918
	Customer advances	(21,971		)	(21,865		)
	Raw material and purchased parts	580			693
	Net inventories	$	75,317		$	59,746
	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 customer advances, which is classified as a liability on the balance sheet.
	At December 31, 2013, work in process and inventoried costs under long-term contracts includes approximately $4.0 million in costs incurred outside the scope of work or in advance of a contract award compared to $5.8 million at September 30, 2013. 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 Costs
	Long-term capitalized contract costs consist of costs incurred on a contract to develop and manufacture a transportation fare system for a customer for which revenue recognition did not begin until the customer began operating the system in the fourth quarter of 2013. These capitalized costs are being amortized into cost of sales based upon the ratio of revenue recorded during the period compared to the revenue expected to be recognized over the term of the contract.

Fair Value of Financial Instruments	'
Fair Value of Financial Instruments	'
	Note 6 — Fair Value of Financial Instruments
	The valuation techniques required to determine fair value 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 fair value of cash equivalents and short term borrowings approximates their cost. The fair value of our available for sale marketable securities is determined based on quoted market prices for identical securities. Derivative financial instruments 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.
	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 decrease 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. At September 30, 2013, the estimated fair value of the liability for contingent consideration was $3.5 million. We paid the Seller $0.7 million during the three months ended December 31, 2013 upon the resolution of certain of the contingencies and at December 31, 2013 the estimated fair value of the remaining  contingent consideration is $2.8 million. 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 $2.8 million is remote, and we have estimated that all contingent consideration amounts will be due within sixteen 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 $2.8 million. There was no change in the fair value of the contingent consideration between the date of the acquisition of NEK and December 31, 2013 other than for payments of amounts to  the Seller; 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.

	Note 7 — Financing Arrangements
	In March 2013, we entered into a note purchase and private shelf agreement pursuant to which we issued $100.0 million of senior unsecured notes, bearing interest at a rate of 3.35% and maturing on March 12, 2025. Interest on these notes is due semi-annually and principal payments are due from 2021 through 2025. 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.
	We have a committed five-year revolving credit agreement (Revolving Credit Agreement) with a group of financial institutions in the amount of $200 million, which expires in May 2017. The available line of credit is reduced by any letters of credit issued under the Revolving Credit Agreement. As of December 31, 2013, there were borrowings totaling $20.0 million under this agreement and there were letters of credit outstanding totaling $20.9 million, which reduce the available line of credit to $159.1 million.
	We have a secured letter of credit facility agreement with a bank (Secured Letter of Credit Facility) that has no expiration date and is cancellable by us at any time upon the completion of certain conditions to the satisfaction of the bank At December 31, 2013 there were letters of credit outstanding under this agreement of $60.9 million. Of our total restricted cash of $69.4 million at December 31, 2013, $68.9 million of this amount was held on deposit in the U.K. as collateral in support of this Secured Letter of Credit 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 $62.7 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 under the Revolving Credit Agreement.
	As of December 31, 2013, we had letters of credit and bank guarantees outstanding totaling $90.8 million, including the letters of credit outstanding under the Revolving Credit Agreement and the Secured Credit Facility described above, which guarantee either our performance or customer advances under certain contracts. In addition, we had financial letters of credit outstanding totaling $12.4 million as of December 31, 2013, which primarily guarantee our payment of certain self-insured liabilities. We have never had a drawing on a letter of credit instrument, nor are any anticipated; therefore, we estimate the fair value of these instruments to be zero.
	We maintain short-term borrowing arrangements in New Zealand and Australia totaling $0.5 million New Zealand dollars (equivalent to approximately $0.4 million) and $3.0 million Australian dollars (equivalent to approximately $2.7 million) to help meet the short- term working capital requirements of our subsidiaries in those countries. At December 31, 2013, no amounts were outstanding under these borrowing arrangements.
	The terms of certain of our lending and credit agreements include provisions that require and/or limit, among other financial ratios and measurements, the permitted levels of debt, coverage of cash interest expense, and under certain circumstances, payments of dividends or other distributions to shareholders. As of December 31, 2013 this agreement does not restrict such distributions to shareholders. As a result of our restatement, we have been unable to comply with covenants requiring us to provide our lenders with audited financial statements and interim financial information on a timely basis. However, we have entered into amendments to our financing arrangements which have included waivers to extend the dates by which we are required to deliver our audited financial statements and interim financial information to May 31, 2014, and as such we are not in default under our lending arrangements or credit agreements.
	Our self-insurance arrangements are limited to certain workers’ compensation plans, automobile liability and product liability claims. Under these arrangements, we self-insure only up to the amount of a specified deductible for each claim. Self-insurance liabilities included in other current liabilities on the balance sheet amounted to $8.6 million and $8.8 million as of December 31, 2013, and September 30, 2013, respectively.

	On March 21, 2013, the Executive Compensation Committee of the Board of Directors (Compensation Committee) 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. On December 12, 2013, the Compensation Committee approved additional awards of 110,812 RSUs with time-based vesting and 152,694 RSUs with performance-based vesting.
	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 are delivered to the recipient following each vesting date.
	The RSUs with time-based vesting that were granted in March 2013 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. The RSUs with time-based vesting that were granted in December 2013 will vest in four equal installments on each of October 1, 2014, 2015, 2016 and 2017, subject to the recipient’s continued service through such date.
	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. The performance period for the performance-based vesting RSUs granted on December 12, 2013 is October 1, 2013 to September 30, 2016. 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 the end of the respective performance period. For the performance-based RSUs granted to date, the vesting will be contingent upon Cubic meeting one of three types of vesting criteria over the performance period. These three categories of vesting criteria consist of revenue growth targets, earnings targets, and return on equity targets. The level at which Cubic’s performs against scalable targets over the performance period will determine the percentage of the RSUs that will ultimately vest.
	Through December 31, 2013, Cubic has granted 690,017 restricted stock units of which 69,994 have vested. At December 31, 2013, the total number of unvested RSUs that are ultimately expected to vest, after consideration of expected forfeitures and estimated vesting of performance-based RSUs is 298,905.
	The following table summarizes our RSU activity for the three months ended December 31, 2013. The weighted-average grant date fair value of each RSU represents the fair market value of one share of our common stock at the grant date:

	As of December 31, 2013, there was $27.5 million of unrecognized compensation cost related to unvested RSUs. This amount is expected to be recognized over a weighted-average period of 1.7 years. Based upon the expected forfeitures and the expected vesting of performance-based RSUs, the aggregate grant-date fair value of unvested RSUs at December 31, 2013 expected to ultimately vest is $13.8 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 year as of December 31, 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 11 — Income Taxes
	Our effective tax rate for the three months ended December 31, 2013 was 22% as compared to 36% for the year ended September 30, 2013. The effective tax rate for the three months ended December 31, 2013 is lower than the year ended September 30, 2013, which reflected the unfavorable impact related to the goodwill impairment loss as well as an increase in the valuation allowance against deferred tax assets.
	The amount of unrecognized tax benefits was $4.6 million as of December 31, 2013 and $4.8 million as of September 30, 2013, exclusive of interest and penalties. At December 31, 2013, the amount of unrecognized tax benefits from permanent tax adjustments that, if recognized, would favorably impact the effective rate was $4.6 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 $2.2 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 December 31, 2013, the tax years open under the statute of limitations in significant jurisdictions include fiscal years 2010-2013 in the U.K., 2008- 2013 in New Zealand and 2010-2013 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 been resolved with federal, state and foreign tax authorities.
	Companies are required to assess whether a valuation allowance should be recorded against their deferred tax assets (DTAs) by jurisdiction based on the consideration of all available evidence, with significant weight given to evidence that can be objectively verified and using a “more likely than not” realization standard. As of September 30, 2013, we evaluated our net DTAs, including an assessment of the cumulative income or loss over the prior three-year and future periods, to determine if a valuation allowance was required. With respect to Australia, we recorded a valuation allowance on net DTAs of approximately $4.0 million. As of December 31, 2013, we continue to assess the need for a valuation allowance on DTAs and will record the related tax effects in the quarter in which a change in circumstance occurs.

Derivative Instruments and Hedging Activities	'
	Note 12 — 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.
	The following table shows the notional principal amounts of our outstanding derivative instruments as of December 31, 2013 and September 30, 2013 (in thousands):
		Notional Principal
		December 31, 2013			September 30, 2013
	Instruments designated as accounting hedges:
	Foreign currency forwards	$	395,767		$	361,337
	Forward starting swap	—			58,415
	Instruments not designated as accounting hedges:
	Foreign currency forwards	$	1,591		$	2,697
	Forward starting swap	55,962			—
	The notional principal amounts for outstanding derivative instruments provide one measure of the transaction volume outstanding and do not represent the amount of our exposure to credit or market loss. Credit risk represents our gross exposure to potential accounting loss on derivative instruments that are outstanding or unsettled if all counterparties failed to perform according to the terms of the contract, based on then-current interest or currency exchange rates at each respective date. Our exposure to credit loss and market risk will vary over time as a function of interest and currency exchange rates. The amount of credit risk from derivative instruments and hedging activities was not material at December 31, 2013 or September 30, 2013. Although the table above reflects the notional principal amounts of our forward starting swaps and foreign exchange instruments, it does not reflect the gains or losses associated with the exposures and transactions that the forward starting swaps and foreign exchange instruments are intended to hedge. The amounts ultimately realized upon settlement of these financial instruments, together with the gains and losses on the underlying exposures, will depend on actual market conditions during the remaining life of the instruments.
	We generally enter into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. We present our derivative assets and derivative liabilities at their gross fair values. We did not have any derivative instruments with credit-risk related contingent features that would require us to post collateral as of December 31, 2013 or September 30, 2013.
	The table below presents the fair value of our derivative financial instruments that qualify for hedge accounting as well as their classification in the Condensed Consolidated Balance Sheets as of December 31, 2013 and September 30, 2013 (in thousands):
				Fair Value

	For the three months ended December 31, 2013, we recognized a gain of $0.4 million related to derivative instruments classified as not highly effective. The amount of gains and losses from derivative instruments and hedging activities classified as not highly effective did not have a material impact on the results of operations for the three months ended December 31, 2012. The amount of estimated unrealized net gains from cash flow hedges which are expected to be reclassified to earnings in the next twelve months is $0.5 million, net of income taxes.
	Forward starting swap
	In connection with a transportation systems contract that we entered in December 2011, we have incurred significant costs to develop the customer’s fare collection system before we begin receiving payments under the contract. In order to finance certain of these costs, we had planned to issue at least $83 million of 10-year fixed rate debt on or about January 1, 2014. As of December 31, 2013, we still plan to issue the debt, but we revised our estimated date of issuance to July 1, 2014.
	Due to concern that market interest rates for the 10-year forward period of January 1, 2014 to January 1, 2024 would change through January 1, 2014, exposing the LIBOR benchmark component of each of the 20 projected semi-annual interest cash flows of that future 10-year period to risk of variability, in July 2012 we entered into a forward-starting 10-year swap contract with a bank to reduce the interest rate variability exposure of the projected interest cash flows. This forward-starting swap had a termination date of January 1, 2014. On December 18, 2013, we modified the forward starting swap such that the termination date is now July 1, 2014. The modified forward-starting swap has a notional amount of $56.0 million, and a pay 1.881% fixed rate, receive 3-month LIBOR, with fixed rate payments due semi-annually on the first day each June and December commencing June 1, 2014 through December 1, 2023, floating payments due quarterly on the first day of each quarter commencing March 1, 2014 through December 2023, and floating reset dates 2 days prior to the first day of each calculation period. The swap contracts accrual period, January 1, 2014 to December 1, 2023 was designed to match the tenor of the planned debt issuance. Prior to the modification of the forward-starting swap on December 18, 2013, the forward starting swap was deemed to be a highly effective cash flow hedge. Upon modification of the forward-starting swap, we did not elect to designate the modified forward-starting swap as an accounting hedge. As such, an amount equal to the fair value of the forward-starting swap immediately prior to the modification of the instrument of $1.0 million will be included in accumulated other comprehensive income (loss) in our Condensed Consolidated Balance Sheet until we issue the fixed rate debt and begin incurring interest on the debt. At the time the debt is issued, we will begin amortizing the accumulated other comprehensive income as a reduction of interest expense over the period that the debt is outstanding. Changes in the fair value of the forward-starting swap subsequent to the date of the modification are recognized in earnings. The change in the fair value of the forward starting swap from the date of the modification to December 31, 2013 resulted in the recognition of income of $0.4 million.
	Foreign currency forwards
	In order to limit our exposure to foreign currency exchange rate risk we generally hedge those commitments greater than $50,000 by using foreign currency exchange forward and option contracts that are denominated in currencies other than the functional currency of the subsidiary responsible for the commitment, typically the British pound, Canadian dollar, Singapore dollar, euro, Swedish krona, New Zealand dollar and Australian dollar. These contracts are designed to be effective hedges regardless of the direction or magnitude of any foreign currency exchange rate change, because they result in an equal and opposite income or cost stream that offsets the change in the value of the underlying commitment.

	Note 14 — Legal Matters
	In November 2011, we received a claim from a public transit authority customer which alleges that the authority incurred a loss of transit revenue due to the inappropriate and illegal actions of one of our former employees, who has pled guilty to the charges. This individual was employed to work on a contract we acquired in a business combination in 2009 and had allegedly been committing these illegal acts from almost two years prior to our acquisition of the contract, until his arrest in May 2011. The transit system was designed and installed by a company unrelated to us. The claim currently seeks recoupment from us of a total amount of $3.9 million for alleged lost revenue, fees and damages. In March 2012, the county superior court entered a default judgment against our former employee and others for $2.9 million based upon the estimated loss of revenue by the public transit authority customer. In 2012, we recorded an accrued cost of $2.9 million within general and administrative expense in the transportation systems segment based upon the court’s assessment of these losses. We have not recorded expense for any amount in excess of the $2.9 million through December 31, 2013 as no other amount of loss is deemed probable. Insurance may cover all, or a portion, of any losses we could ultimately incur for this matter. However, any potential insurance proceeds will not be recognized in the financial statements until receipt of any such proceeds is probable.
	In October and December of 2013, and January of 2014, lawsuits were filed in the United States District Court for the Northern District of Illinois, Eastern Division against us and one of our transit customers alleging variously, among other things, breach of contract, violation of the Illinois Consumer Fraud Act, unjust enrichment and violation of the Electronic Funds Act. In January 2014 these cases were consolidated into a single case and the Plaintiffs are seeking to have the case certified as a class action. Plaintiffs variously claim, among other things, that: (i) they were wrongly charged for calling the call center that we operate for patrons of our transit customer, (ii) they were wrongly charged for a transfer and a second fare, (iii) they were not credited the cost of a transit card even after registration of the card, as is required under the terms of the cardholder agreement, and (iv) they were double charged for rides taken. We are undertaking the defense of the transit customer pursuant to our contractual obligations to that customer. We are investigating the matter and plan to vigorously defend this lawsuit. Due to the preliminary nature of this case, we cannot estimate the probability of loss or any range of estimate of possible loss.
	Also in October 2013, a lawsuit was filed in the Circuit Court of Cook County, Illinois, County Department, Chancery Division against our same transit customer alleging conversion and unjust enrichment.  The plaintiff alleges his bank debit card was charged two dollars and twenty-five cents for his ride on the transit system rather than the ride being charged to his transit fare card. This plaintiff is also seeking to have his case certified as a class action for all patrons whose bank cards were charged in the same manner. We are investigating the matter and we are undertaking the defense pursuant to our contractual obligations to our transit customer.
	We plan to vigorously defend this lawsuit. Our Motion to Dismiss was granted on April 30, 2014 and the plaintiff has until May 27, 2014 to file an Amended Complaint. Due to the preliminary nature of this case, we cannot estimate the probability of loss or any range of estimate of possible loss.
	We are not a party to any other material pending proceedings and we consider all other matters to be ordinary proceedings incidental to the business. We believe the outcome of these other proceedings will not have a materially adverse effect on our financial position, results of operations, or cash flows.

	Acquisition subsequent to December 31, 2013 - Intific
	On February 28, 2014 we acquired all of the outstanding capital stock of Intific Inc. (Intific), an Austin, Texas based advanced technology company focused on software and game-based solutions in modeling and simulation, training and education, cyber  warfare, and neuroscience. The acquisition of Intific expands the portfolio of services and customer base of our Cubic Defense  Systems (CDS) segment. Subsequent to December 31, 2013, beginning upon our acquisition of Intific on February 28, 2014, we began including the results of operations of Intific in our consolidated financial statements.
	The purchase agreement states that the cost of the acquisition is approximately $12.6 million, adjusted by the difference between the net working capital acquired and the targeted working capital amounts. The acquisition date fair value of the consideration transferred is estimated to be $12.9 million. In February 2014, we paid cash of approximately $10.7 million from our existing cash resources. In February 2014 we also recorded a liability of approximately $2.2 million as an estimate of the cash that will be paid to the seller in connection with the working capital settlement and cash that will be owed to the seller due to the passage of time.
	The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):
	Customer Relationships	$	2
	Technology	0.7
	Backlog	0.7
	Other Intangible assets	0.2
	Accounts Receivable	1.5
	Deferred tax liabilities, net	(0.5		)
	Accounts payable and accrued expenses	(0.6		)
	Other net assets acquired	0.6
	Net identifiable assets acquired	4.6
	Goodwill	8.3
	Net assets acquired	$	12.9
	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 amortization related to identified intangible assets that is not expected to be deductible for tax purposes, net of acquisition consideration that is a tax deductible expense. The estimated fair value of the accounts receivable and accounts payable and accrued expenses will be finalized as further information is received from the seller regarding these items.
	The fair values of purchased intangibles were determined using the valuation methodology deemed to be the most appropriate for each type of asset being valued. The customer relationships and backlog valuation used the excess earnings approach and the technology valuation used the replacement cost approach.
	The intangible assets will be amortized beginning on the acquisition date 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 two years from the date of acquisition and is not expected to be deductible for tax purposes.
	The goodwill resulting from the acquisition consists primarily of the synergies expected from combining the operations of Intific with our existing CDS 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 CDS segment and is not 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 Intific for fiscal years 2014 through 2018 is as follows (in millions):
	Year Ended
	September 30,
