Basis for Presentation
	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, with the exceptions discussed within the Audit Committee Investigation and Correction of Immaterial Errors subsections below, considered necessary to fairly state the financial position of Cubic Corporation at December 31, 2014 and September 30, 2014; the results of its operations for the three-month periods ended December 31, 2014 and 2013; and its cash flows for the three-month periods ended December 31, 2014 and 2013. Operating results for the three-month period ended December 31, 2014 are not necessarily indicative of the results that may be expected for the year ending September 30, 2015. 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, 2014.
	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.
	Audit Committee Investigation
	Our Audit Committee has conducted an investigation with the assistance of Latham & Watkins LLP and Deloitte FAS LLP to review our controls and procedures in connection with programs that are accounted for under the percentage of completion method. Through the application of the Company’s internal controls, management identified an issue which led to the investigation. As a result of the investigation, the Audit Committee and management of the Company have together determined that as of September 30, 2014, the total estimated costs of certain of our Cubic Defense Systems (CDS) segment contracts were inappropriately reduced during its accounting close for the year ended September 30, 2014. The inappropriate reduction of the estimated costs to complete these contracts resulted in the overstatement of CDS sales and operating income by approximately $750,000 for the fourth quarter and full year of fiscal 2014.
	Correction of Immaterial Errors
	During the accounting close for our March 31, 2015 financial statements, we identified certain errors, unrelated to the matters described in the paragraph above, in our September 30, 2014 financial statements. These errors included an overstatement of revenue recognition on one contract and the understatement of cost of sales on a small number of contracts. The cumulative impact of these errors resulted in an overstatement of the Company’s operating income for the year ended September 30, 2014 of $1.6 million.
	The cumulative amount of the errors described in the two paragraphs above overstated the Company’s operating income for fiscal 2014 by $2.4 million and understated the Company’s operating income for 2013 and prior years, cumulatively, by $0.3 million. The impact of correcting the above mentioned errors in the quarter ended December 31, 2014 understated operating income for the quarter by $2.1 million. The impact of correcting these errors (overstated) understated the following amounts in the quarter ended December 31, 2014 (in thousands):
		Audit Committee
		Investigation
		Error		Other Errors			Total Errors
	Net sales:
	Products	$	747	$	517		$	1,264
	Costs and expenses:
	Products	—		138			138
	Services	—		438			438
	Selling, general and administrative	—		(1,385		)	(1,385		)
		—		(809		)	(809		)
	Operating income	747		1,326			2,073
	Income before income taxes	747		1,326			2,073
	Income taxes	299		490			789
	Net income attributable to Cubic	$	448	$	836		$	1,284
	Based on a qualitative and quantitative analysis of these errors, management concluded that all such errors are cumulatively and individually considered immaterial to the 2014 financial statements and are immaterial to the expected full year results for 2015 and had no effect on the trend of financial results. As such, these errors have been corrected in the financial statements for the quarter ended December 31, 2014.
	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 for the year ended September 30, 2014.
	Recent Accounting Pronouncements
	In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists which requires companies to present in the financial statements an unrecognized tax benefit as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward except to the extent such items are not available or not intended to be used at the reporting date to settle any additional income taxes that would result from the disallowance of a tax position. In such instances, the unrecognized tax benefit is required to be presented in the financial statements as a liability and not be combined with deferred tax assets. This amendment is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Accordingly, we adopted this standard in the first quarter of fiscal year 2015. This adoption did not have a significant impact on our financial statements.
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. The amendments contained in this update change the criteria for reporting discontinued operations and enhance the reporting requirements for discontinued operations. Under the revised standard, a discontinued operation must represent a strategic shift that has or will have a major effect on an entity’s operations and financial results. Examples could include a disposal of a major line of business, a major geographical area, a major equity method investment, or other major parts of an entity. The revised standard will also allow an entity to have certain continuing cash flows or involvement with the component after the disposal. Additionally, the standard requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This ASU is effective for reporting periods beginning after December 15, 2014 with early adoption permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issue. This adoption is not expected to have a significant impact on our financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 outlines a comprehensive revenue recognition model and supersedes most current revenue recognition guidance and will require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. ASU 2014-09 will be effective for us starting in the first quarter of fiscal 2018. However, on April 1, 2015, the FASB voted to propose a one-year deferral to the effective date, but to permit entities to adopt one year earlier if they choose (i.e., the original effective date). The proposal will be subject to the FASB’s due process requirement, which includes a period for public comments. ASU 2014-09 allows for two methods of adoption: (a) “full retrospective” adoption, meaning the standard is applied to all periods presented, or (b) “modified retrospective” adoption, meaning the cumulative effect of applying ASU 2014-09 is recognized as an adjustment to the fiscal 2018 opening retained earnings balance. We have not yet determined which method of adoption we will select. As the new standard will supersede substantially all existing revenue guidance affecting us under GAAP, it could impact revenue and cost recognition on a significant number of contracts across our business segments, in addition to our business processes and our information technology systems. As a result, our evaluation of the effect of the new standard will likely extend over several future periods.
	In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern, which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and provide related footnote disclosures. The guidance is effective for annual and interim reporting periods beginning on or after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. This adoption is not expected to have a significant impact on our financial statements.
	In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The new standard modifies current guidance on consolidation under the variable interest model and the voting model. ASU 2015-02 will be effective for the Company beginning in the first quarter of fiscal 2016. We are currently evaluating the impact of the ASU 2015-02 on our financial statements.

Acquisitions
	Note 2 — 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 condensed consolidated financial statements since the respective date of each acquisition.
	DTECH LABS, Inc.
	On December 16, 2014 we acquired all of the outstanding capital stock of DTECH LABs, Inc. (DTECH). DTECH, based in Sterling, VA, is a provider of modular networking and baseband communications equipment and adds networking capability to our secure communications business in our Cubic Defense Systems (CDS) segment. In addition, this acquisition expands the portfolio of product offerings and the customer base of our CDS segment.
	For the three months ending December 31, 2014, the amount of DTECH’s sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $1.0 million and $0.8 million, respectively. Included in DTECH’s operating results for the three months ended December 31, 2014 are $0.8 million of transaction and acquisition related costs before related income taxes.
	The purchase agreement states that the cost of the acquisition is approximately $99.5 million, adjusted by the difference between the net working capital acquired and the targeted working capital amounts and adjusted for other acquisition related payments made upon closing, plus a contingent amount of up to $15.0 million based upon DTECH’s achievement of revenue and gross profit targets in the future. The acquisition date fair value of the consideration transferred is estimated to be $99.2 million. In December 2014, we paid cash of approximately $83.4 million and have recorded a liability of $14.9 million as an estimate of the fair value of additional cash consideration that will be due to the seller in the future. The fair value of the additional consideration is made up of two components, the holdback consideration and the contingent consideration.
	Approximately $11.4 million of cash consideration (Holdback Consideration) will be paid to the seller over time when certain events occur in the future. The fair value of the Holdback Consideration is estimated to approximate $11.0 million using a discounted cash flow model, based upon the expected timing of the payment of the Holdback Consideration. In addition to the Holdback Consideration, we will pay the seller up to $15.0 million of contingent cash consideration based upon DTECH’s achievement of revenue and gross profit targets. The purchase agreement specifies independent revenue and gross profit targets for the period from our acquisition of DTECH through September 30, 2015, and separately for each of fiscal 2016 and fiscal 2017. The total fair value of the contingent consideration has been estimated at $3.9 million using a real options approach (see Note 5 for further discussion of fair value measurements). The contingent consideration liability will be re-measured to fair value at each reporting date until the contingency is resolved and any changes in fair value will be recognized in earnings.
	The acquisition of DTECH was paid for with a combination of funds from our existing cash resources and borrowings on our revolving credit facility. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):
	Customer relationships	$	35.1
	Non compete agreements	0.7
	Backlog	2.1
	Cash	0.9
	Accounts receivable	5.4
	Inventory	4.1
	Warranty obligation	(0.4		)
	Tax liabilities	(3.3		)
	Accounts payable and accrued expenses	(3.4		)
	Other net assets acquired	0.2
	Net identifiable assets acquired	41.4
	Goodwill	57.8
	Net assets acquired	$	99.2
	The estimated fair values of the assets acquired and liabilities assumed, including the fair value of purchased intangibles, are preliminary estimates pending the finalization of our valuation analyses. The estimated fair value of the accounts receivable, inventory, warranty obligation, accounts payable and accrued expenses will be finalized as further information is received from the seller regarding these items and analysis of this information is completed.
	The preliminary 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 agreements 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 two years from the date of acquisition and is expected to be deductible for tax purposes.
	The goodwill resulting from the acquisition consists primarily of the synergies expected from combining the operations of DTECH with our existing CDS business, including the synergies expected from combining the networking and secure communications technologies of DTECH, and complimentery products that will enhance our overall product and service portfolio. The goodwill also consists of the value of the assembled workforce that became our employees following the close of the acquisition. The amount recorded as goodwill is allocated to our CDS 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 DTECH for future periods is as follows (in millions):
	Year Ended
	September 30,
	2015	$	9.2
	2016	8.0
	2017	6.8
	2018	5.5
	2019	4.1
	Thereafter	4.3
	Intific
	On February 28, 2014 we acquired all of the outstanding capital stock of Intific Inc. (Intific). Intific is focused on software and game-based solutions in modeling and simulation, training and education, cyber warfare, and neuroscience. The acquisition of Intific expanded the portfolio of services and customer base of our Cubic Defense Systems (CDS) segment.
	For the three months ended December 31, 2014, the amount of Intific’s sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $3.4 million and $0.7 million, respectively.
	The acquisition date fair value of the consideration transferred was $12.4 million. Through December 31, 2014, we have paid cash of approximately $11.2 million to the seller and as of December 31, 2014 we have accrued a liability of $1.2 million for the remaining cash to be paid.
	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 assets	1.5
	Accounts payable and accrued expenses	(0.6		)
	Deferred tax liabilities	(1.5		)
	Other net assets acquired	0.5
	Net identifiable assets acquired	5
	Goodwill	7.4
	Net assets acquired	$	12.4
	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 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 the amortization expense is not expected to be deductible for tax purposes.
	The net deferred tax assets and liabilities offset each other to a negligible amount. However, the deferred tax liabilities of $1.5 million 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 deferred tax assets of $1.5 million primarily related to the future tax deduction for the cancellation of unvested options.
	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.
	The estimated amortization expense related to the intangible assets recorded in connection with our acquisition of Intific for future periods is as follows (in millions):
	Year Ended
	September 30,
	2015	$	0.9
	2016	0.7
	2017	0.6
	2018	0.5
	2019	0.2
Thereafter	0.1
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, 2014, the amount of ITMS’ sales and net loss after taxes included in our Condensed Consolidated Statement of Income were $10.0 million and $1.1 million, respectively. 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 for the three months ended December 31, 2013 are $0.4 million of transaction costs.
The acquisition date fair value of the consideration transferred was $72.2 million. We paid the seller cash of $69.0 million in November 2013 and in May 2014, we paid the remaining cash of $3.2 million.
The following table summarizes the 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		)

Accounts payable and accrued expenses	(4.6		)
Other net assets acquired	2.6
Net identifiable assets acquired	31.4
Goodwill	40.8
Net assets acquired	$	72.2
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 such amortization will not 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.

No adjustments were made for transaction expenses, other adjustments that do not reflect ongoing operations or for operating efficiencies or synergies. There were no material, nonrecurring pro forma adjustments directly attributable to the business combinations included in the reported pro forma sales and net income (loss) attributable to Cubic.  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, 2013, and it does not purport to project our future operating results.

Net Income Per Share
	Note 3 — 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 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. 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 4 — Balance Sheet Details
	Marketable Securities
	Marketable securities consist of fixed time deposits 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 (loss). 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,
		2014			2014
	Trade and other receivables	$	16,363		$	30,593
	Long-term contracts:
	Billed	115,049			121,871
	Unbilled	267,747			258,074
	Allowance for doubtful accounts	(299		)	(489		)
	Total accounts receivable	398,860			410,049
	Less estimated amounts not currently due	(14,950		)	(15,870		)
	Current accounts receivable	$	383,910		$	394,179
	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, 2014 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, 2014 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,
		2014			2014
	Work in process and inventoried costs under long-term contracts	$	49,925		$	58,440
	Materials and purchased parts	2,964			125
	Customer advances	(12,050		)	(19,790		)
	Net inventories	$	40,839		$	38,775
	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 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, 2014, work in process and inventoried costs under long-term contracts includes approximately $1.1 million in costs incurred outside the scope of work or in advance of a contract award compared to $2.3 million at September 30, 2014. We believe it is probable that we will recover the costs inventoried at December 31, 2014, 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 fiscal quarter of 2013. These capitalized costs are being recognized as 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, which is through January 2024. Long-term capitalized costs that were recognized as cost of sales totaled $1.8 million and $0.5 million for the quarters ended December 31, 2014 and 2013, respectively. The balance of long-term capitalized costs at December 31, 2014 is expected to be recognized as cost of sales in approximately equal quarterly amounts in future months through the term of the contract.
	Deferred Compensation Plan
	We have a non-qualified deferred compensation plan offered to a select group of highly compensated employees. The plan provides participants with the opportunity to defer a portion of their compensation in a given plan year. The liabilities associated with the non-qualified deferred compensation plan are included in other long-term liabilities in our Condensed Consolidated Balance Sheets and totaled $10.5 million and $9.5 million at December 31, 2014 and September 30, 2014, respectively.
	In the first quarter of fiscal 2015, we began making contributions to a rabbi trust to provide a source of funds for satisfying a portion of these deferred compensation liabilities. The total carrying value of the assets set aside to fund deferred compensation liabilities as of December 31, 2014 was $2.4 million. These assets are classified as other non-current assets and consist of insurance contracts with a carrying value of $2.0 million and marketable securities with a carrying value of $0.4 million. The carrying value of the life insurance contracts is based upon the cash surrender value of the policies. The marketable securities in the rabbi trust are carried at fair value, which is based upon quoted market prices for identical securities. Changes in the carrying value of the deferred compensation liability, and changes in the carrying value of the assets held in the rabbi trust are reflected in our Condensed Consolidated Statements of Income.

Fair Value of Financial Instruments
Fair Value of Financial Instruments
	Note 5 — 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 investments approximates their cost. The fair value of our 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 liability to the seller of DTECH is revalued to its fair value each period and any 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. The fair value of the contingent consideration was estimated using a real options approach. Each annual payment was modeled using a portfolio of long and short digital options written on the underlying earnings metric (revenue or gross profit). The strike price for each option is the respective earnings threshold as specified in the agreement, and the spot price is calibrated to the revenue and gross profit forecast by calculating the present value of the corresponding projected earnings metric using a risk-adjusted discount rate. The volatility for the underlying earnings metrics was estimated to be 22% based on analysis of comparable guideline public companies. The risk-free rate was selected based on the quoted yields for U.S. Treasury securities with terms matching the earn-out payment period. The inputs to this model are significant unobservable inputs and therefore represent Level 3 measurements within the fair value hierarchy. There was no change in the fair value of the contingent consideration between the date of the acquisition of DTECH and December 31, 2014; therefore, no contingent consideration expense was recorded in the quarter. 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 6 — 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, through March 2016 we may from time to time issue and sell, and the purchasers may in their sole discretion purchase, 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, 2014, there were borrowings totaling $60.0 million under this agreement and there were letters of credit outstanding totaling $17.5 million, which reduce the available line of credit to $122.5 million.
	We have a secured letter of credit facility agreement with a bank (Secured Letter of Credit Facility) which is cancellable by us at any time upon the completion of certain conditions to the satisfaction of the bank. At December 31, 2014 there were letters of credit outstanding under this agreement of $46.8 million. Restricted cash at December 31, 2014 of $69.1 million 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 $62.6 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 under the Revolving Credit Agreement.
	As of December 31, 2014, we had letters of credit and bank guarantees outstanding totaling $68.3 million, including the letters of credit outstanding under the Revolving Credit Agreement and the Secured Letter of Credit Facility, which guarantee either our performance or customer advances under certain contracts. In addition, we had financial letters of credit outstanding totaling $8.2 million as of December 31, 2014, 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 $2.5 million) to help meet the short- term working capital requirements of our subsidiaries in those countries. At December 31, 2014, 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, 2014, these agreements do not restrict such distributions to shareholders. We have been unable to comply with covenants requiring us to provide our lenders with interim financial information on a timely basis. However, we have entered into consents with our lenders which have included extensions to the dates by which we are required to deliver our interim financial information to May 29, 2015, 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 $8.5 million and $9.1 million as of December 31, 2014 and September 30, 2014, respectively.

	Long Term Equity Incentive Plan
	On March 21, 2013, the Executive Compensation Committee of the Board of Directors (Compensation Committee) approved a long- term equity incentive award program. Through December 31, 2014, the Compensation Committee has granted 542,488 RSU’s with time-based vesting and 488,604 RSU’s with performance-based vesting under this program.
	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 granted with time-based vesting generally vest in four equal installments on each of the four October 1 dates following the grant date, subject to the recipient’s continued service through such vesting date.
	The performance-based RSUs granted to participants vest over three-year performance periods based on Cubic’s achievement of performance goals established by the Compensation Committee over the performance periods, subject to the recipient’s continued service through the end of the respective performance periods. 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 performs against scalable targets over the performance periods will determine the percentage of the RSUs that will ultimately vest.
	Through December 31, 2014, Cubic has granted 1,031,092 restricted stock units of which 175,880 have vested. The grant date fair value of each restricted stock unit is the fair market value of one share of our common stock at the grant date. At December 31, 2014, 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 378,262.
	The following table summarizes our RSU activity:
		Unvested Restricted Stock Units
				Weighted-
				Average Grant-
		Number of Shares		Date Fair Value

	As of December 31, 2014, there was $32.8 million of unrecognized compensation cost related to unvested RSUs. Based upon the expected forfeitures and the expected vesting of performance based RSUs, the aggregate fair value of RSUs expected to ultimately vest is $18.1 million. This amount is expected to be recognized over a weighted-average period of 1.6 years.
	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, 2014. 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.

Income Taxes
	Note 10 — Income Taxes
	Our effective tax rate for the three months ended December 31, 2014 was 12% as compared to 22% for the year ended September 30, 2014. The effective tax rate for the three months ended December 31, 2014 is lower than the year ended September 30, 2014, primarily as a result of the reinstatement of the U.S. federal research and development credit during the first quarter of fiscal 2015.
	The amount of net unrecognized tax benefits was $7.6 million as of December 31, 2014 and $4.7 million as of September 30, 2014, exclusive of interest and penalties. The increase in net unrecognized tax benefits during the quarter was primarily related to acquisitions. At December 31, 2014, the amount of net unrecognized tax benefits from permanent tax adjustments that, if recognized, would favorably impact the effective rate was $4.8 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 $1.0 million of the net 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, 2014, the tax years open under the statute of limitations in significant jurisdictions include fiscal years 2011-2014 in the U.S. We believe we have adequately provided for uncertain tax issues that have not yet been resolved with federal, state and foreign tax authorities.
	We are required to assess whether a valuation allowance should be recorded against our 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 December 31, 2014, 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. Through December 31, 2014, a valuation allowance of $14.3 million has been established for certain deferred tax assets related to state tax credits, certain foreign operating losses and other foreign assets.

Derivative Instruments and Hedging Activities
	Note 11 — 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 loss 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, 2014 and September 30, 2014 (in thousands):
		Notional Principal
		December 31,			September 30,

	Instruments designated as accounting hedges:
	Foreign currency forwards	$	260,358		$	249,628
	Instruments not designated as accounting hedges:
	Foreign currency forwards	$	140,059		$	136,955
	Included in the amounts not designated as accounting hedges above at December 31, 2014 and September 30, 2014 are foreign currency forwards with notional principal amounts of $130.1 million and $132.1 million, respectively, that have been designed to manage exposure to foreign currency exchange risks, and for which the gains or losses of the changes in fair value of the forwards has approximately offset an equal and opposite amount of gains or losses related to the foreign currency exposure.
	The notional principal amounts for outstanding derivative instruments provide one measure of the transaction volume outstanding and do not represent the amount of the Company’s exposure to credit or market loss. Credit risk represents the Company’s 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. The Company’s 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 for the three months ended December 31, 2014 and 2013. Although the table above reflects the notional principal amounts of the Company’s foreign exchange instruments, it does not reflect the gains or losses associated with the exposures and transactions that the 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.
	The Company generally enters into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. The Company presents its derivative assets and derivative liabilities at their gross fair values. The Company did not have any derivative instruments with credit-risk related contingent features that would require it to post collateral as of December 31, 2014 or September 30, 2014.

	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, 2014. 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 estimated unrealized net gains from cash flow hedges which are expected to be reclassified to earnings in the next twelve months is $0.7 million, net of income taxes.
	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.
	Forward starting swap
	In July 2012 we entered into a forward starting swap contract with a bank in order to manage our exposure to fluctuations in interest rates related to an anticipated financing. This forward starting swap terminated on July 1, 2014. During the quarter ended December 31, 2013 we recognized income of $0.4 million related to the change in the fair value of the forward starting swap.

Legal Matters
	Note 13 — Legal Matters
	In November 2011, we received a claim from a public transit authority customer which alleged 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 transit authority sought recoupment from us of a total amount of $4.5 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. In July 2014, we entered into a settlement agreement with the customer for a cash payment of $2.6 million plus an assignment of forty percent of any insurance proceeds we receive under relevant insurance policies. In June 2014 we reduced our accrued costs to $2.6 million. In March 2015, our insurer paid us $1.8 million related to this matter and we paid our customer forty percent of this amount, or $0.7 million, in connection with the settlement agreement with the customer. We recognized a gain of the net amount of $1.1 million as a reduction of general and administrative expenses in the first quarter of fiscal 2015.
	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 are vigorously defending this lawsuit. As this case remains in its early stages, 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. This lawsuit was later amended and refiled in May 2014. The plaintiff alleged 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 was also seeking to have his case certified as a class action for all patrons whose bank cards were charged in the same manner. We undertook the defense of this matter pursuant to our contractual obligations to our transit customer. We entered into a settlement agreement with the plaintiff in March 2015 whereby we paid the plaintiff $4,000 and the plaintiff voluntarily withdrew his case.
	In October 2014, a lawsuit was filed in the United States District Court, Northern District of Illinois against us and our same transit customer alleging infringement of various patents held by the plaintiff. We are investigating the matter and plan to vigorously defend the lawsuit. We are also undertaking defense of our customer in this matter pursuant to our contractual obligations to that customer. Due to the preliminary nature of this case, we cannot estimate the probability of loss or any range of estimate of possible loss.
	In January 2015, we received $3.6 million as a settlement of a claim related to the reimbursement of expenses we incurred primarily in 2014 for a proposal prepared for a prospective customer of our transportation systems business. This $3.6 million settlement will be recorded as a reduction of research and development and general and administrative expenses in the quarter ending March 31, 2015.
	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.

	Note 14 — Subsequent Events
	In February 2015, we restructured our defense services and defense systems businesses into a single business called Cubic Global Defense (CGD) to better align our defense business organizational structure with customer requirements, increase operational efficiencies and improve collaboration and innovation across the Company. In connection with the restructuring we incurred a charge of $5.4 million in the second quarter of fiscal 2015. After this restructuring there is now a single, combined management structure for CDS and MSS. However, for segment financial reporting purposes, in the future we will continue to report the financial results of CDS and MSS separately. These two reporting segments have been renamed Cubic Global Defense Systems (CGD Systems) and Cubic Global Defense Services (CGD Services), respectively. There have been no significant changes in the operations that are included in these segments as the results of the restructuring.

Audit Committee Investigation
	Audit Committee Investigation
	Our Audit Committee has conducted an investigation with the assistance of Latham & Watkins LLP and Deloitte FAS LLP to review our controls and procedures in connection with programs that are accounted for under the percentage of completion method. Through the application of the Company’s internal controls, management identified an issue which led to the investigation. As a result of the investigation, the Audit Committee and management of the Company have together determined that as of September 30, 2014, the total estimated costs of certain of our Cubic Defense Systems (CDS) segment contracts were inappropriately reduced during its accounting close for the year ended September 30, 2014. The inappropriate reduction of the estimated costs to complete these contracts resulted in the overstatement of CDS sales and operating income by approximately $750,000 for the fourth quarter and full year of fiscal 2014.
Correction of Immaterial Errors
	Correction of Immaterial Errors
	During the accounting close for our March 31, 2015 financial statements, we identified certain errors, unrelated to the matters described in the paragraph above, in our September 30, 2014 financial statements. These errors included an overstatement of revenue recognition on one contract and the understatement of cost of sales on a small number of contracts. The cumulative impact of these errors resulted in an overstatement of the Company’s operating income for the year ended September 30, 2014 of $1.6 million.
	The cumulative amount of the errors described in the two paragraphs above overstated the Company’s operating income for fiscal 2014 by $2.4 million and understated the Company’s operating income for 2013 and prior years, cumulatively, by $0.3 million. The impact of correcting the above mentioned errors in the quarter ended December 31, 2014 understated operating income for the quarter by $2.1 million. The impact of correcting these errors (overstated) understated the following amounts in the quarter ended December 31, 2014 (in thousands):
		Audit Committee

	Net sales:

	Income taxes	299		490			789
	Net income attributable to Cubic	$	448	$	836		$	1,284
	Based on a qualitative and quantitative analysis of these errors, management concluded that all such errors are cumulatively and individually considered immaterial to the 2014 financial statements and are immaterial to the expected full year results for 2015 and had no effect on the trend of financial results. As such, these errors have been corrected in the financial statements for the quarter ended December 31, 2014.
	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 for the year ended September 30, 2014.
Recent Accounting Pronouncements
	Recent Accounting Pronouncements
	In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists which requires companies to present in the financial statements an unrecognized tax benefit as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward except to the extent such items are not available or not intended to be used at the reporting date to settle any additional income taxes that would result from the disallowance of a tax position. In such instances, the unrecognized tax benefit is required to be presented in the financial statements as a liability and not be combined with deferred tax assets. This amendment is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Accordingly, we adopted this standard in the first quarter of fiscal year 2015. This adoption did not have a significant impact on our financial statements.
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. The amendments contained in this update change the criteria for reporting discontinued operations and enhance the reporting requirements for discontinued operations. Under the revised standard, a discontinued operation must represent a strategic shift that has or will have a major effect on an entity’s operations and financial results. Examples could include a disposal of a major line of business, a major geographical area, a major equity method investment, or other major parts of an entity. The revised standard will also allow an entity to have certain continuing cash flows or involvement with the component after the disposal. Additionally, the standard requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This ASU is effective for reporting periods beginning after December 15, 2014 with early adoption permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issue. This adoption is not expected to have a significant impact on our financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 outlines a comprehensive revenue recognition model and supersedes most current revenue recognition guidance and will require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. ASU 2014-09 will be effective for us starting in the first quarter of fiscal 2018. However, on April 1, 2015, the FASB voted to propose a one-year deferral to the effective date, but to permit entities to adopt one year earlier if they choose (i.e., the original effective date). The proposal will be subject to the FASB’s due process requirement, which includes a period for public comments. ASU 2014-09 allows for two methods of adoption: (a) “full retrospective” adoption, meaning the standard is applied to all periods presented, or (b) “modified retrospective” adoption, meaning the cumulative effect of applying ASU 2014-09 is recognized as an adjustment to the fiscal 2018 opening retained earnings balance. We have not yet determined which method of adoption we will select. As the new standard will supersede substantially all existing revenue guidance affecting us under GAAP, it could impact revenue and cost recognition on a significant number of contracts across our business segments, in addition to our business processes and our information technology systems. As a result, our evaluation of the effect of the new standard will likely extend over several future periods.
	In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern, which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and provide related footnote disclosures. The guidance is effective for annual and interim reporting periods beginning on or after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. This adoption is not expected to have a significant impact on our financial statements.
	In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The new standard modifies current guidance on consolidation under the variable interest model and the voting model. ASU 2015-02 will be effective for the Company beginning in the first quarter of fiscal 2016. We are currently evaluating the impact of the ASU 2015-02 on our financial statements.
