Organization, Consolidation and Presentation of Financial Statements [Abstract]

Summary of Significant Accounting Policies

All references to the “Company” and “Kratos” refer to Kratos Defense & Security Solutions, Inc., a Delaware corporation, and its subsidiaries.


(a)	Basis of Presentation

The information as of June 30, 2019 and for the three and six months ended June 30, 2019 and July 1, 2018 is unaudited. The condensed consolidated balance sheet as of December 30, 2018 was derived from the Company’s audited consolidated financial statements at that date. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented. The results have been prepared in accordance with the instructions to Form 10-Q and do not necessarily include all information and footnotes necessary for presentation in accordance with accounting principles generally accepted in the U.S. (“GAAP”). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes included in the Company’s audited annual consolidated financial statements for the fiscal year ended December 30, 2018, included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2019 (the “Form 10-K”). Interim operating results are not necessarily indicative of operating results expected in subsequent periods or for the year as a whole.

As discussed in “Acquisition” in Note 2, on February 27, 2019, the Company acquired 80.1% of the issued and outstanding shares of capital stock of Florida Turbine Technologies, Inc. (“FTT Inc.”), and 80.1% of the membership interests in FTT CORE, LLC (“FTT Core” and, together with FTT Inc.,“FTT”), for an aggregate purchase price of approximately $60 million. FTT is now the Kratos Turbine Technologies Division (the “KTT Division”), which is focused on the development and production of small, affordable, high-performance, jet engines for the next generation of tactical weapon systems and tactical jet unmanned aerial systems (“UAS”). The KTT Division is included in the Kratos Government Solutions (“KGS”) Segment.


(b)	Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company, its 100% owned subsidiaries and its majority owned subsidiaries, FTT Inc. and FTT Core, each of which is 80.1% owned. All inter-company transactions have been eliminated in consolidation. Noncontrolling interest consists of the remaining 19.9% interest in FTT Inc. and FTT Core. See Note 12 for further information related to the redeemable noncontrolling interest.


(c)	Fiscal Year

The Company has a 52/53 week fiscal year ending on the last Sunday of the calendar year. The three and six month periods ended June 30, 2019 and July 1, 2018 consisted of 13-week periods. There are 52 calendar weeks in the fiscal years ending on December 29, 2019 and December 30, 2018.

(d) Accounting Estimates

There have been no significant changes in the Company’s accounting estimates for the six months ended June 30, 2019 as compared to the accounting estimates described in the Form 10-K.

(e) Accounting Standards Updates

In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases, also referred to as “ASC 842”. ASU 2016-02 requires that lessees recognize assets and liabilities for the rights and obligations underlying leases with a lease term of more than one year. The amendments in this ASU are effective for annual periods beginning after December 15, 2018. In July 2018, the FASB issued ASU 2018-11, Leases; Targeted Improvements, which, among other things, allows a company to elect an optional transition method that applies the new lease requirements through a cumulative-effect adjustment in the period of adoption. The Company adopted this standard on December 31, 2018 using the optional transition method, and, as a result, did not recast prior period unaudited condensed comparative financial statements. All prior period amounts and disclosures are presented under Accounting Standards Codification Topic 840, Leases (“ASC 840”).

The Company has revised its controls and processes to address the new lease standard and has completed the implementation and data input for our lease accounting software tool. The Company has elected the package of practical expedients, which, among other things, allows carry-forward of prior lease classifications under the prior standard. However, the Company has not elected to adopt the hindsight practical expedient and is therefore maintaining the lease terms previously determined under the prior lease standard. For all new and modified leases after adoption of the ASU, the Company has taken the component election allowing the Company to account for lease components together with non-lease components in the calculation of the lease asset and corresponding liability. Adoption of the new standard resulted in the recording of additional lease assets and lease liabilities on the unaudited condensed consolidated balance sheet. No cumulative-effect adjustment was recognized as the amount was not material, and the impact on the Company’s results of operations and cash flows was also not material. See Note 8 for additional disclosures.

In February 2018, the FASB issued ASU 2018-02 (“ASU 2018-02”), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”). ASU 2018-02 provides entities the option to reclassify tax effects to retained earnings from AOCI which are impacted by the Tax Cuts and Jobs Act (“TCJA”). This ASU is effective for fiscal years beginning after December 15, 2018 but early adoption is permitted. The Company adopted this standard on December 31, 2018. The Company has a full valuation allowance for all tax benefits related to AOCI, and therefore, there are no tax effects to be reclassified to retained earnings.


(f)	Fair Value of Financial Instruments

The carrying amounts and the related estimated fair values of the Company’s long-term debt financial instruments not measured at fair value on a recurring basis at June 30, 2019 and December 30, 2018 are presented in Note 10. The carrying value of all other financial instruments, including cash equivalents, accounts receivable, accounts payable, accrued expenses, billings in excess of cost and earnings on uncompleted contracts, income taxes payable and short-term debt, approximated their estimated fair values at June 30, 2019 and December 30, 2018 due to the short-term nature of these instruments.

Business Combinations [Abstract]

Acquisition

On February 27, 2019, the Company acquired 80.1% of the issued and outstanding shares of capital stock of FTT Inc., and 80.1% of the membership interests in FTT Core for an aggregate purchase price of approximately $60 million. The purchase price was $33 million in cash, with approximately $17.7 million paid at close and approximately $15.3 million to be paid over a three-year period, subject to adjustments for transaction expenses, indebtedness, cash on hand, certain amounts payable or potentially payable to employees of FTT and post-closing working capital adjustments, and 1,825,406 shares of common stock (with a value of approximately $27 million).

FTT is a leading turbomachinery design and manufacturing company specializing in engineering, development, and testing of gas turbines, propulsion components, and systems for military and commercial applications. FTT is now the KTT Division, which is focused on the development and production of small, affordable, high-performance, jet engines for the next generation of tactical weapon systems and tactical jet UAS. The KTT Division is included in the KGS Segment.

The excess of the purchase price over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed in the acquisition was allocated to goodwill. The goodwill represents the value the Company expects to be created by enabling it to accelerate FTT’s small engine development programs, and facilitate integration of these leading-edge engine solutions with evolving Kratos tactical systems.

Simultaneously with the execution of the Purchase Agreement among the Company and the Sellers (as defined in such agreement) (the “Purchase Agreement”) and completion of the acquisition, the Company, FTT Inc., FTT Core and the Sellers

entered into an exchange agreement (the “Exchange Agreement”) pursuant to which, among other things, (i) FTT Core was converted into a Delaware corporation, (ii) beginning in January 2024, the Holders (as defined in the Exchange Agreement) will have an annual right (the “Put Right”) to sell all of the minority interests in FTT Inc. and FTT Core (the “Minority Interests”) to the Company at a purchase price based on an assumed enterprise value of 12 times the trailing 12 months EBITDA of FTT Inc., FTT Core and each of their respective subsidiaries (the “Acquired Companies”), subject to adjustment as set forth in the Exchange Agreement (the “Minority Interest Purchase Price”) (provided, however, that following certain events, including a change of control, the Put Right will be accelerated and the Minority Interest Purchase Price will be increased to 14 times the trailing 12 months EBITDA of the Acquired Companies), and (iii) beginning in January 2025, the Company will have an annual right to purchase all of the Minority Interests from the Holders at the Minority Interest Purchase Price.

The transaction has been accounted for using the acquisition method of accounting, which requires, among other things, that the assets acquired, the liabilities assumed, and the noncontrolling interest be recognized at their fair values as of the acquisition date. The fair value measurements are based primarily on significant inputs not observable in the marketplace and thus represent Level 3 measurements. The following table summarizes the provisional allocation of the purchase price over the estimated fair values of the major assets acquired, liabilities assumed, and noncontrolling interest (in millions):



Accounts receivable	$	7.3
Unbilled receivables	4.9
Inventoried costs	11.7

Property and equipment	9.7

As of February 27, 2019, net liabilities include $7.7 million of current liabilities and $1.3 million of long-term liabilities. There was no contingent purchase consideration associated with the acquisition of an 80.1% majority interest in FTT. The amounts above represent the provisional fair value estimates as of March 31, 2019 and are subject to subsequent adjustment as the Company obtains additional information during the measurement period and finalizes its fair value estimates. If an adjustment to the provisional amounts recognized is subsequently identified during the measurement period, the Company will recognize the adjustment in the reporting period in which the adjustment amount is determined, including recording cumulative catch-up changes to depreciation, amortization, or other income statement effects recognized in completing the initial accounting. The provisional identifiable intangible asset estimates include customer relationships of $11.2 million with a useful life of 10 years, in-process research and development of $6.0 million that will commence amortization at the completion of the development project, backlog of $2.2 million with a useful life of 2 years, and trade name of $0.4 million with a useful life of 1 year. Any subsequent adjustments to these fair value estimates occurring during the measurement period will result in an adjustment to goodwill. The Company also established a deferred tax liability of $4.4 million for the increase in the financial statement basis of the acquired assets of FTT and a corresponding increase in goodwill. The goodwill recorded in this transaction is not expected to be tax-deductible.

The amounts of revenue and operating income of FTT included in the Company's condensed consolidated statement of operations for the three months ended June 30, 2019 are $17.2 million and $1.6 million, respectively. The amounts of revenue and operating income of FTT included in the Company's condensed consolidated statement of operations for the six months ended June 30, 2019 are $21.4 million and $1.7 million, respectively. Included in the merger and acquisition expenses, for the three and six months ended June 30, 2019 are transaction expenses of $0.1 million and $1.3 million, respectively, related to the acquisition of FTT.

A summary of the consideration paid for the acquired ownership in FTT is as follow:

Revenue Recognition

6 Months Ended

Jun. 30, 2019

Revenue from Contract with Customer [Abstract]

Revenue Recognition

The Company recognizes revenue in accordance with Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606 revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these goods or services.

To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. The majority of the Company’s contracts have a single performance obligation as the promise to

transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on the relative estimated standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected-cost-plus-margin approach, under which the Company forecasts the expected costs of satisfying a performance obligation and then adds an appropriate margin for that distinct good or service.

Remaining Performance Obligations

The Company calculates revenues from remaining performance obligations as the dollar value of the remaining performance obligations on executed contracts. On June 30, 2019, the Company had approximately $620.3 million of remaining performance obligations. The Company expects to recognize approximately 41% of the remaining performance obligations as revenue in 2019, an additional 34% by 2020, and the balance thereafter.

Contract Estimates

Due to the nature of the work required to be performed on many performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. It is common for the Company’s long-term contracts to contain award fees, incentive fees, or other provisions that can either increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. Variable consideration is estimated at the most likely amount to which the Company is expected to be entitled. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available.

Contracts are often modified to account for changes in contract specifications and requirements. Contract modifications are considered to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the Company’s contract modifications are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price, and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

There is a Company-wide standard and disciplined quarterly Estimate at Completion (EAC) process in which management reviews the progress and execution of outstanding performance obligations. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes in estimates of revenues and costs. The risks and opportunities include management's judgment about the ability and cost to achieve the schedule (e.g., the number and type of milestone events), technical requirements (e.g., a newly-developed product versus a mature product) and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to complete the performance obligation (e.g., to estimate increases in wages and prices for materials and related support cost allocations), execution by subcontractors, the availability and timing of funding from customers and overhead cost rates, among other variables.

Based on this analysis, any quarterly adjustments to net sales, cost of sales, and the related impact to operating income are recognized as necessary in the period they become known. These adjustments may result from positive program performance, and may result in an increase in operating income during the performance of individual performance obligations, if it is determined the Company will be successful in mitigating risks surrounding the technical, schedule and cost aspects of those performance obligations or realizing related opportunities. Likewise, these adjustments may result in a decrease in operating income if it is determined the Company will not be successful in mitigating these risks or realizing related opportunities. Changes in estimates of net sales, cost of sales and the related impact to operating income are recognized quarterly on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation's percentage of completion. A significant change in one or more of these estimates could affect the profitability of one or more of the Company’s performance obligations. When estimates of total costs to be incurred on a performance obligation exceed total estimates of revenue to be earned, a provision for the entire loss on the performance obligation is recognized in the period the loss is determined. No adjustment on any one contract was material to

the Company’s unaudited condensed consolidated financial statements for the six-month periods ended June 30, 2019, and July 1, 2018.

Contract Assets and Liabilities

For each of the Company’s contracts, the timing of revenue recognition, customer billings, and cash collections results in a net contract asset or liability at the end of each reporting period. Fixed-price contracts are typically billed to the customer either using progress payments, whereby amounts are billed monthly as costs are incurred or work is completed, or performance based payments, which are based upon the achievement of specific, measurable events or accomplishments defined and valued at contract inception. Cost-type contracts are typically billed to the customer on a monthly or semi-monthly basis.

Contract assets consist of unbilled receivables, primarily related to long-term contracts where revenue recognized under the cost-to-cost method exceeds amounts billed to customers. Unbilled receivables are classified as current assets and, in accordance with industry practice, include amounts that may be billed and collected beyond one year due to the long term nature of many of the Company’s contracts. Accumulated contract costs in unbilled receivables include direct production costs, factory and engineering overhead, production tooling costs, and, for government contracts, recovery of allowable general and administrative expenses. Unbilled receivables also include certain estimates of variable consideration described above. These contract assets are not considered a significant financing component of the Company’s contracts as the payment terms are intended to protect the customer in the event the Company does not perform on its obligations under the contract.

Contract liabilities include advance payments and billings in excess of revenue recognized. Certain customers make advance payments prior to the satisfaction of the Company’s performance obligations on the contract. These amounts are recorded as contract liabilities until such performance obligations are satisfied, either over time as costs are incurred or at a point in time when deliveries are made. Contract liabilities are not a significant financing component as they are generally utilized to pay for contract costs within a one-year period or are used to ensure the customer meets contractual requirements.

Net contract assets and liabilities are as follows (in millions):



	June 30, 2019		December 30, 2018		Net Change
Contract assets	$	169.1	$	172.8	$	(3.7	)
Contract liabilities	$	40.6	$	37.0	$	3.6
Net contract assets	$	128.5	$	135.8	$	(7.3	)

The change in the balances of the Company’s contract assets and liabilities primarily results from the advance payments from customers exceeding reductions from recognition of revenue as performance obligations were satisfied and related billings. There were no significant impairment losses related to any receivables or contract assets arising from the Company’s contracts with customers during the six months ended June 30, 2019. For the three and six months ended June 30, 2019, the Company recognized revenue of $16.6 million and $21.3 million, respectively, that was previously included in the beginning balance of contract liabilities.

Discontinued Operations and Disposal Groups [Abstract]

Discontinued Operations

On February 28, 2018, the Company entered into a Stock Purchase Agreement to sell the operations of Kratos Public Safety & Security Solutions, Inc., a Delaware corporation and wholly owned subsidiary of the Company (“PSS”), to Securitas Electronic Security, Inc., a Delaware corporation (“Buyer”). On June 11, 2018, the Company completed the sale of all of the issued and outstanding capital stock of PSS to Buyer for a purchase price of $69 million in cash, subject to a closing net working capital adjustment (the “Transaction”). The Company and the Buyer are currently in a dispute regarding the closing net working capital adjustment. The amount in dispute is approximately $8 million.

The Company currently expects to receive approximately $70 million of aggregate net cash proceeds from the Transaction, after taking into account amounts to be paid by the Company pursuant to a negotiated transaction services agreement between the Company and Buyer, receipt by the Company of approximately $7.0 million in net working capital retained by the Company, and associated transaction fees and expenses, excluding the impact of the final settlement and determination of the closing working capital adjustment. The Company currently expects that the net working capital retained by the Company will be settled in 2019 once certain legacy projects are completed and the project close-out process has been completed. Through June 30, 2019, approximately $1.5 million has been collected related to these legacy projects. The Company incurred approximately $2.7 million of transaction related costs, which was reflected in the loss from discontinued operations in the periods incurred. The Company currently expects to recognize a net break-even on the sale of the PSS business once the aggregate net proceeds described above have been collected, excluding the impact of the final settlement and determination of the closing net working capital adjustment. Any changes or adjustments to the expected net proceeds will be reflected in future periods.

The following table presents the results of discontinued operations (in millions):



	Three Months Ended						Six Months Ended

Revenue and operating results for the three and six months ended June 30, 2019 reflected the work performed in relation to tasks on the legacy projects retained by the Company. Operating results for 2018 are through the date of divestiture of June 11, 2018. Revenue and operating results for the six months ended July 1, 2018 were impacted by approximately $1.8 million and $2.0 million, respectively, of cost adjustments on certain security system deployment projects for a mass transit authority. Transaction expenses of $1.9 million and $2.7 million primarily comprised of investment advisory fees, legal fees, and other direct transaction expenses related to the Transaction were included in Other (income) expense, net for the three and six months ended July 1, 2018, respectively. Other (income) expense for the three and six months ended June 30, 2019 includes a $3.6 million gain as a result of the release of an indemnification liability following the lapse of the statute of limitations associated with a potential tax liability that was recorded in 2015 as part of the sale of the Company’s Electronics Products Division. Depreciation expense included in Selling, general and administrative expenses was $0.0 million and $0.1 million for the three months ended June 30, 2019 and July 1, 2018, respectively, and $0.0 million and $0.1 million for the six months ended June 30, 2019 and July 1, 2018, respectively.

Earnings Per Share [Abstract]
Net Income (Loss) per Common Share	Net Income (Loss) per Common Share The Company calculates net income (loss) per share in accordance with FASB Accounting Standards Codification Topic 260, Earnings per Share (Topic 260). Under Topic 260, basic net income (loss) per common share attributable to the Kratos shareholders is calculated by dividing net income (loss) attributable to Kratos by the weighted-average number of common shares outstanding during the reporting period. Diluted net income (loss) per common share attributable to the Kratos shareholders reflects the effects of potentially dilutive securities. The dilutive impact of potentially dilutive common shares is determined by applying the treasury stock method. Shares from stock options and awards, excluded from the calculation of diluted net income (loss) per share because their inclusion would have been anti-dilutive, were 0.0 million and 0.0 million for the three and six months ended June 30, 2019, respectively, and 0.4 million and 0.4 million for the three and six months ended July 1, 2018.

Leases

Jun. 30, 2019

Leases [Abstract]

Leases

The Company leases certain facilities, office space, vehicles and equipment. Lease assets and lease liabilities are recognized at the commencement of an arrangement where it is determined at inception that a lease exists. Lease assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. These assets and liabilities are initially recognized based on the present value of lease payments over the lease term calculated using an incremental borrowing rate generally applicable to the location of the lease asset, unless the implicit rate is readily determinable. Lease assets also include any upfront lease payments made and exclude lease incentives. Lease terms include options to extend or terminate the lease when it is reasonably certain that those options will be exercised. The Company has operating lease arrangements with lease and non-lease components. The non-lease components in these arrangements are not significant when compared to the lease components. For all operating leases, the Company accounts for the lease and non-lease components as a single component.

Variable lease payments are generally expensed as incurred and include certain index-based changes in rent, certain non-lease components, such as maintenance and other services provided by the lessor, and other charges included in the lease. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and the expense for these short-term leases is recognized on a straight-line basis over the lease term.

The depreciable life of lease assets and leasehold improvements is limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

As a result of a lease modification for our expanded facilities in Colorado, in the first quarter of 2019, the Company was required to reassess the classification of the lease which previously had been accounted for as an operating lease. This reassessment resulted in the reclassification of the operating lease to a $39.3 million finance lease.

Income Tax Disclosure [Abstract]

Income Taxes

A reconciliation of the income tax expense (benefit) from continuing operations computed by applying the statutory federal income tax rate of 21% to income from continuing operations before income taxes to the income tax provision for the three and six months ended June 30, 2019 and July 1, 2018 was as follows (in millions):



	For the Three Months Ended						For the Six Months Ended
	June 30, 2019			July 1, 2018			June 30, 2019			July 1, 2018

Total income tax provision	$	2.5		$	0.1		$	1.0		$	1.0

In assessing the Company’s ability to realize deferred tax assets, management considers, on a periodic basis, whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As such, management has

determined that it is appropriate to maintain a full valuation allowance against the Company’s U.S. federal, combined state and certain foreign deferred tax assets, with the exception of an amount equal to its deferred tax liabilities, which can be expected to reverse over a definite life.

Federal and state income tax laws impose restrictions on the utilization of net operating loss (“NOL”) and tax credit carryforwards in the event that an “ownership change” occurs for tax purposes, as defined by Section 382 of the Internal Revenue Code of 1986, as amended (“Section 382”). In general, an ownership change occurs when shareholders owning 5% or more of a “loss corporation” (a corporation entitled to use NOLs or other loss carryovers) have increased their ownership of stock in such corporation by more than 50 percentage points during any three-year period. The annual base Section 382 limitation is calculated by multiplying the loss corporation’s value at the time of the ownership change by the greater of the long-term tax-exempt rate determined by the Internal Revenue Service in the month of the ownership change or the two preceding months. This base limitation is subject to adjustments, including an increase for built-in gains recognized in the five-year period after the ownership change.

In March 2010, an “ownership change” occurred that will limit the utilization of NOL carryforwards. In July 2011, another “ownership change” occurred. The March 2010 ownership change limitation is more restrictive. In prior years, the Company acquired corporations with NOL carryforwards at the date of acquisition (“Acquired NOLs”). The Acquired NOLs are subject to separate limitations that may further restrict the use of Acquired NOLs. As a result, the Company’s federal annual utilization of NOL carryforwards was limited to $27.0 million a year for the five years succeeding the March 2010 ownership change and $11.6 million for each year thereafter subject to separate limitations for Acquired NOLs. If the entire limitation amount is not utilized in a year, the excess can be carried forward and utilized in future years.

For the six months ended June 30, 2019, there was no impact of such limitations on the income tax provision, since the amount of taxable income did not exceed the annual limitation amount. However, future equity offerings or acquisitions that have equity as a component of the purchase price could also cause an “ownership change.” If and when any other “ownership change” occurs, utilization of the NOLs or other tax attributes may be further limited.

As discussed elsewhere, deferred tax assets relating to the NOL and credit carryforwards are offset by a full valuation allowance. In addition, utilization of state tax loss carryforwards is dependent upon sufficient taxable income apportioned to the states.

The Company is subject to taxation in the U.S. and various state and foreign tax jurisdictions. The Company’s tax years for 2000 and later are subject to examination by the U.S. and state tax authorities due to the existence of the NOL carryforwards. Generally, the Company’s tax years for 2002 and later are subject to examination by various foreign tax authorities as well.

During 2018 the Company was notified by the Internal Revenue Service that its federal income tax return for the calendar year ending December 27, 2015 had been selected for examination. The Company is currently in the process of responding to the information requested.

As of December 30, 2018, the Company had $17.7 million of unrecognized tax benefits that, if recognized, would impact the Company’s effective income tax rate, subject to possible offset by an increase in the deferred tax asset valuation allowance. During the six months ended June 30, 2019, unrecognized tax benefits increased by $1.9 million relating to various current year positions.

The Company recognizes interest and penalties related to unrecognized tax benefits in its provision for income taxes. For the six months ended June 30, 2019 and July 1, 2018, the Company recorded an expense for interest and penalties of $1.1 million and $0.4 million, respectively. For the six months ended June 30, 2019 and July 1, 2018, there was no material benefit recorded related to the removal of interest and penalties. The Company believes that it is reasonably possible that as much as $0.4 million of the liabilities for uncertain tax positions will expire within twelve months of June 30, 2019 due to the expiration of various applicable statutes of limitations.

Debt

6 Months Ended

Debt Disclosure [Abstract]

Debt

(a) Issuance of 6.5% Senior Secured Notes due 2025

In November 2017, the Company issued and sold $300 million aggregate principal amount of 6.5% Senior Secured Notes due 2025 (the “6.5% Notes”) in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Act”). The Company incurred debt issuance costs of $6.6 million associated with the

new 6.5% Notes. The Company utilized the net proceeds from the sale of the 6.5% Notes, as well as cash from its recent equity offering to extinguish the outstanding 7% Notes (as defined below). The total reacquisition price of the 7% Notes was $385.2 million, including a $12.0 million call premium, and $0.3 million of accrued interest.

The 6.5% Notes are governed by the Indenture, dated as of November 20, 2017 (the “Indenture”), among the Company, the Company’s existing and future domestic subsidiaries parties thereto (the “Subsidiary Guarantors”) and Wilmington Trust, National Association, as trustee and collateral agent. A Subsidiary Guarantor can be released from its guarantee if (a) all of the capital stock issued by such Subsidiary Guarantor or all or substantially all of the assets of such Subsidiary Guarantor are sold or otherwise disposed of; (b) the Company designates such Subsidiary Guarantor as an Unrestricted Subsidiary (as defined in the Indenture); (c) the Company exercises its legal defeasance option or its covenant defeasance option; or (d) upon satisfaction and discharge of the Indenture or payment in full in cash of the principal of, premium, if any, and accrued and unpaid interest on the 6.5% Notes.

The 6.5% Notes bear interest at a rate of 6.5% per year from the date of original issuance or from the most recent payment date on which interest has been paid or provided for. Interest on the 6.5% Notes is payable in arrears on May 30 and November 30 of each year, beginning on May 30, 2018. The 6.5% Notes are fully and unconditionally guaranteed by the Subsidiary Guarantors.

The 6.5% Notes and the guarantees (as set forth in the Indenture) are the Company’s senior secured obligations and are equal in right of payment with all other senior obligations of the Subsidiary Guarantors’ existing and future secured debt to the extent of the assets securing that secured debt. The Company’s obligations under the 6.5% Notes are secured by a first priority lien on substantially all of the Company’s assets and the assets of the Subsidiary Guarantors, except with respect to accounts receivable, inventory, deposit accounts, securities accounts, cash, securities and general intangibles (other than intellectual property), on which the holders of the 6.5% Notes have a second priority lien, junior to the lien securing the Company’s obligations under the Credit Agreement (as defined below).

The 6.5% Notes will be redeemable, in whole or in part, at any time on or after November 30, 2020 at the respective redemption prices specified in the Indenture. In addition, the Company may redeem up to 40% of the 6.5% Notes before November 30, 2020 with the net proceeds of certain equity offerings. The Company may also redeem some or all of the 6.5% Notes before November 30, 2020 at a redemption price of 100% of the principal amount thereof plus accrued and unpaid interest, to, but excluding, the redemption date, if any, plus a “make whole” premium. In addition, during each 12-month period commencing on the issue date and ending on or prior to November 30, 2020, the Company may redeem up to 10% of the original aggregate principal amount of the 6.5% Notes issued under the Indenture at a redemption price of 103.000% of the principal amount thereof, plus accrued and unpaid interest, to, but excluding, the date of redemption, if any. The Company may also be required to make an offer to purchase the 6.5% Notes upon a change of control and certain sales of its assets.

The Indenture contains covenants limiting, among other things, the Company’s ability and the Subsidiary Guarantors’ ability to: (a) pay dividends on or make distributions or repurchase or redeem the Company’s capital stock or make other restricted payments; (b) incur additional debt and guarantee debt; (c) prepay, redeem or repurchase certain debt; (d) issue certain preferred stock or similar equity securities; (e) make loans and investments; (f) sell assets; (g) incur liens; (h) consolidate, merge, sell or otherwise dispose of all or substantially all of the Company’s assets; (i) enter into transactions with affiliates; and (j) enter into agreements restricting the Company’s ability and certain of its subsidiaries’ ability to pay dividends. These covenants are subject to a number of exceptions. As of June 30, 2019, the Company was in compliance with the covenants contained in the Indenture governing the 6.5% Notes.

The terms of the Indenture require that the net cash proceeds from asset dispositions be either utilized to (i) repay or prepay amounts outstanding under the Credit Agreement unless such amounts are reinvested in similar collateral, (ii) permanently reduce other indebtedness, (iii) make an investment in assets that replace the collateral of the 6.5% Notes or (iv) a combination of (i), (ii) and (iii). To the extent there are any remaining net proceeds from the asset disposition after application of (i), (ii) and (iii), such amounts are required to be utilized to repurchase the 6.5% Notes at par.

The Indenture also provides for events of default which, if any such event occurs, would permit or require the principal, premium, if any, interest, if any, and any other monetary obligations on all the then-outstanding 6.5% Notes to become or to be declared due and payable immediately.

As of June 30, 2019, there was $300.0 million of 6.5% Notes outstanding.

(b) Other Indebtedness

Credit Agreement

On November 20, 2017, the Company entered into an amended and restated credit and security agreement (the “Credit Agreement”), with the lenders from time to time party thereto, SunTrust Bank, as Agent (the “Agent”), PNC Bank, National Association (“PNC Bank”), as Joint Lead Arranger and Documentation Agent, and SunTrust Robinson Humphrey, Inc. (“SunTrust”), as Joint Lead Arranger and Sole Book Runner. The Credit Agreement established a five-year senior secured revolving credit facility in the aggregate principal amount of $90.0 million (subject to a potential increase of the aggregate principal amount to $115.0 million, subject to the Agent’s and applicable lenders’ approval as described therein), consisting of a subline for letters of credit in an amount not to exceed $50.0 million, as well as a swingline loan in an aggregate principal amount at any time outstanding not to exceed $10.0 million. The obligations under the Credit Agreement are secured by (i) a first priority lien on the Company’s accounts receivable, inventory, deposit accounts, securities accounts, cash, securities and general intangibles (other than intellectual property) and (ii) a second priority lien, junior to the lien securing the Company’s 6.5% Notes, on all of the Company’s other assets.

Borrowings under the revolving credit facility may take the form of a base rate revolving loan, Eurodollar revolving loan or swingline loan. Base rate revolving loans and swingline loans will bear interest at a rate per annum equal to the sum of the Applicable Margin (as defined in the Credit Agreement) from time to time in effect plus the highest of (i) the Agent’s prime lending rate, as in effect at such time, (ii) the federal funds rate, as in effect at such time, plus 0.50% per annum and (iii) the Adjusted LIBO Rate (as defined in the Credit Agreement) determined at such time for an interest period of one month, plus 1.00% per annum. Eurodollar revolving loans will bear interest at a rate per annum equal to the sum of the Applicable Margin from time to time in effect plus the Adjusted LIBO Rate. The Applicable Margin varies between 1.00%-1.50% for base rate revolving loans and swingline loans and 2.00%-2.50% for Eurodollar loans, and is based on several factors including the Company’s then-existing borrowing base and the lenders’ total commitment amount and revolving credit exposure. The calculation of the Company’s borrowing base takes into account several items relating to the Company and its subsidiaries, including amounts due and owing under billed and unbilled accounts receivable, then held eligible raw materials inventory, work-in-process inventory, and applicable reserves.

The Credit Agreement contains certain covenants, which include, but are not limited to, restrictions on indebtedness, liens, and investments, and limits on other various payments, as well as a financial covenant relating to a minimum fixed charge coverage ratio. Events of default under the terms of the Credit Agreement include, but are not limited to: failure of the Company to pay any principal of any loans in full when due and payable; failure of the Company to pay any interest on any loan or any fee or other amount payable under the Credit Agreement within three business days after the date when due and payable; failure of the Company or any of its subsidiaries to comply with certain covenants and agreements, subject to applicable grace periods and/or notice requirements; any representation, warranty or statement made in or pursuant to the Credit Agreement or any related writing or any other material information furnished by the Company or any of its subsidiaries to the Agent or the lenders proving to be false or erroneous; and the occurrence of an event or condition having or reasonably likely to have a material adverse effect, which includes a material adverse effect on the business, operations, condition (financial or otherwise) or prospects of the Company or the ability of the Company to repay its obligations. Where an event of default arises from certain bankruptcy events, the commitments will automatically and immediately terminate and the principal of, and interest then outstanding on, all of the loans will become immediately due and payable. Subject to certain notice requirements and other conditions, upon the occurrence of an event of default, including the occurrence of a condition having or reasonably likely to have a material adverse effect, commitments may be terminated and the principal of, and interest then outstanding on, all of the loans may become immediately due and payable. As of June 30, 2019, no event of default had occurred and the Company believes that events or conditions having a material adverse effect, giving rise to an acceleration of any amounts outstanding under the Credit Agreement, have not occurred and the likelihood of such events or conditions occurring is remote.

The measurement of a minimum fixed charge coverage ratio under the Credit Agreement was modified in November 2017 to require measurement if Excess Availability (as defined in the Credit Agreement) is less than 50% of the lesser of the borrowing base or the total commitment amount.

On June 11, 2018, the Company entered into a first amendment (the “First Amendment”) to the amended and restated Credit Agreement. Among other things, the First Amendment permitted the sale of the PSS business, provided that certain conditions, including application of the proceeds in accordance with the terms of documents governing the Company’s outstanding indebtedness, were satisfied.

As of June 30, 2019, there were no borrowings outstanding on the Credit Agreement and $5.7 million was outstanding on letters of credit, resulting in net borrowing base availability of $64.8 million. The Company was in compliance with the financial

covenants of the Credit Agreement and its amendments as of June 30, 2019.

Fair Value of Long-term Debt

Carrying amounts and the related estimated fair values of the Company’s long-term debt financial instruments not measured at fair value on a recurring basis at June 30, 2019 and December 30, 2018 are presented in the following table:



	As of June 30, 2019						As of December 30, 2018
$ in millions	Principal		Carrying Amount		Fair Value		Principal		Carrying Amount		Fair Value
Total long-term debt including current portion	$	300.0	$	294.6	$	322.5	$	300.0	$	294.2	$	305.3

The fair value of the Company’s long-term debt was based upon actual trading activity (Level 1, Observable inputs -quoted prices in active markets).

As of June 30, 2019, the difference between the carrying amount of $294.6 million and the principal amount of $300.0 million presented in the table above is the unamortized debt issuance costs of $5.4 million, which are being accreted to interest expense over the term of the related debt. As of December 30, 2018, the difference between the carrying amount of $294.2 million and the principal amount of $300.0 million presented in the table above is the unamortized debt issuance costs of $5.8 million, which are being accreted to interest expense over the term of the related debt.

Segment Reporting [Abstract]

Segment Information

The Company operates in two reportable segments. The KGS reportable segment is comprised of an aggregation of KGS operating segments, including the microwave electronic products, satellite communications, modular systems, defense and rocket support services, and turbine technologies operating segments. The Unmanned Systems (“US”) reportable segment consists of its unmanned aerial system and unmanned ground and seaborne system businesses. The KGS and US segments provide products, solutions and services for mission critical national security programs. KGS and US customers primarily include national security related agencies, the U.S. Department of Defense (the “DoD”), intelligence agencies and classified agencies, and to a lesser degree, international government agencies and domestic and international commercial customers.

The Company organizes its reportable segments based on the nature of the products, solutions and services offered. Transactions between segments are generally negotiated and accounted for under terms and conditions similar to other government and commercial contracts. This presentation is consistent with the Company’s operating structure. In the following table total operating income from continuing operations of the reportable business segments is reconciled to the corresponding consolidated amount. The reconciling item “unallocated corporate expense, net” includes costs for certain stock-based compensation programs (including stock-based compensation costs for stock options, employee stock purchase plan and restricted stock units), the effects of items not considered part of management’s evaluation of segment operating performance, merger and acquisition expenses, corporate costs not allocated to the segments, and other miscellaneous corporate activities.

Revenues, depreciation and amortization, and operating income generated by the Company’s reportable segments for the three and six month periods ended June 30, 2019 and July 1, 2018 are as follows (in millions):

Redeemable Noncontrolling Interest	Jun. 30, 2019
Noncontrolling Interest [Abstract]
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest As discussed in “Acquisition” in Note 2, in connection with the Company’s acquisition of FTT, the Holders have certain rights (“Put Rights”), (i) beginning in January 2024, the Holders will have an annual Put Right to sell all of the Minority Interests to the Company at a purchase price based on an assumed enterprise value of 12 times the trailing 12 months EBITDA of FTT Inc., FTT Core and each of their respective subsidiaries (the “Acquired Companies”), subject to adjustment as set forth in the Exchange Agreement (provided, however, that following certain events, including a change of control, the Put Right will be accelerated and the Minority Interest Purchase Price will be increased to 14 times the trailing 12 months EBITDA of the Acquired Companies); and (ii) beginning in January 2025, the Company will have an annual right to purchase all of the Minority Interests from the Holders at the Minority Interest Purchase Price. The Company adjusts the carrying value of such redeemable noncontrolling interest based on an allocation of subsidiary earnings based on ownership interest. Redeemable noncontrolling interest is recorded outside of permanent equity at the higher of its carrying value or management’s estimate of the amount (the “Redemption Amount”) that the Company could be required to pay in connection with the Put Rights. Adjustments to Redemption Amount will have a corresponding effect on net income per share attributable to Kratos shareholders. As of June 30, 2019, the management estimate of the Redemption Amount of these Put Rights that the Company could be required to pay was less than the carrying value and no adjustment of the carrying value of the redeemable noncontrolling interest was required.

Significant Customers	6 Months Ended
Significant Customers	Jun. 30, 2019
Risks and Uncertainties [Abstract]
Significant Customers	Significant Customers Revenue from the U.S. Government, which includes foreign military sales, includes revenue from contracts for which the Company is the prime contractor as well as those for which the Company is a subcontractor and the ultimate customer is the U.S. Government. The KGS and US segments have substantial revenue from the U.S. Government. Sales to the U.S. Government amounted to approximately $133.9 million and $106.6 million, or 71% and 70% of total Kratos revenue, for the three months ended June 30, 2019 and July 1, 2018, respectively, and $250.8 million and $207.5 million, or 72% and 71% of total Kratos revenue for the six months ended June 30, 2019 and July 1, 2018, respectively.

Commitments and Contingencies	6 Months Ended
Commitments and Contingencies	Jun. 30, 2019
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In addition to commitments and obligations in the ordinary course of business, the Company is subject to various claims, pending and potential legal actions for damages, investigations relating to governmental laws and regulations and other matters arising out of the normal conduct of the Company’s business. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its condensed consolidated financial statements. An estimated loss contingency is accrued in the condensed consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including but not limited to the procedural status of the matter in question, the presence of complex or novel legal theories, and the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes and, as such, are not meaningful indicators of its potential liability. The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. The amount of ultimate loss may differ from these estimates. It is possible that cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies. Whether any losses finally determined in any claim, action, investigation or proceeding could reasonably have a material effect on the Company’s business, financial condition, results of operations or cash flows will depend on a number of variables, including the timing and amount of such losses; the structure and type of any remedies; the monetary significance any such losses, damages or remedies may have on the condensed consolidated financial statements; and the unique facts and circumstances of the particular matter that may give rise to additional factors. Legal and Regulatory Matters U.S. Government Cost Claims The Company’s contracts with the DoD are subject to audit by the Defense Contract Audit Agency (“DCAA”). As a result of these audits, from time to time the Company is advised of claims concerning potential disallowed, overstated or disputed costs. For example, during the course of recent audits of the Company’s contracts, the DCAA is closely examining and questioning certain of the established and disclosed practices that it had previously audited and accepted. The Company’s personnel regularly scrutinizes costs incurred and allocated to contracts with the U.S. Government for compliance with regulatory standards. For those Company subsidiaries and fiscal years which have not yet been audited by the DCAA or for those audits which are in process which have not been completed by the DCAA, the Company cannot reasonably estimate the range of loss, if any, that may result from audits and reviews in which it is currently involved given the inherent difficulty in predicting regulatory action, fines and penalties, if any, and the various remedies and levels of judicial review available to the Company in the event of an adverse finding. As a result, the Company has not recorded any liability related to these matters. Other Litigation Matters The Company is subject to normal and routine litigation arising from the ordinary course and conduct of business and, at times, as a result of acquisitions and dispositions. Such disputes include, for example, commercial, employment, intellectual property, environmental and securities matters. The aggregate amounts accrued related to these matters are not material to the total liabilities of the Company. The Company intends to defend itself in any such matters and does not currently believe that the outcome of any such matters will have a material adverse impact on the Company’s financial condition, results of operations or cash flows.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Jun. 30, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The information as of June 30, 2019 and for the three and six months ended June 30, 2019 and July 1, 2018 is unaudited. The condensed consolidated balance sheet as of December 30, 2018 was derived from the Company’s audited consolidated financial statements at that date. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented. The results have been prepared in accordance with the instructions to Form 10-Q and do not necessarily include all information and footnotes necessary for presentation in accordance with accounting principles generally accepted in the U.S. (“GAAP”). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes included in the Company’s audited annual consolidated financial statements for the fiscal year ended December 30, 2018, included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2019 (the “Form 10-K”). Interim operating results are not necessarily indicative of operating results expected in subsequent periods or for the year as a whole. As discussed in “Acquisition” in Note 2, on February 27, 2019, the Company acquired 80.1% of the issued and outstanding shares of capital stock of Florida Turbine Technologies, Inc. (“FTT Inc.”), and 80.1% of the membership interests in FTT CORE, LLC (“FTT Core” and, together with FTT Inc.,“FTT”), for an aggregate purchase price of approximately $60 million. FTT is now the Kratos Turbine Technologies Division (the “KTT Division”), which is focused on the development and production of small, affordable, high-performance, jet engines for the next generation of tactical weapon systems and tactical jet unmanned aerial systems (“UAS”). The KTT Division is included in the Kratos Government Solutions (“KGS”) Segment.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company, its 100% owned subsidiaries and its majority owned subsidiaries, FTT Inc. and FTT Core, each of which is 80.1% owned. All inter-company transactions have been eliminated in consolidation. Noncontrolling interest consists of the remaining 19.9% interest in FTT Inc. and FTT Core. See Note 12 for further information related to the redeemable noncontrolling interest.
Fiscal Year	Fiscal Year The Company has a 52/53 week fiscal year ending on the last Sunday of the calendar year. The three and six month periods ended June 30, 2019 and July 1, 2018 consisted of 13-week periods. There are 52 calendar weeks in the fiscal years ending on December 29, 2019 and December 30, 2018.
Accounting Estimates	Accounting Estimates There have been no significant changes in the Company’s accounting estimates for the six months ended June 30, 2019 as compared to the accounting estimates described in the Form 10-K.
Accounting Standards Updates	Accounting Standards Updates In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases, also referred to as “ASC 842”. ASU 2016-02 requires that lessees recognize assets and liabilities for the rights and obligations underlying leases with a lease term of more than one year. The amendments in this ASU are effective for annual periods beginning after December 15, 2018. In July 2018, the FASB issued ASU 2018-11, Leases; Targeted Improvements, which, among other things, allows a company to elect an optional transition method that applies the new lease requirements through a cumulative-effect adjustment in the period of adoption. The Company adopted this standard on December 31, 2018 using the optional transition method, and, as a result, did not recast prior period unaudited condensed comparative financial statements. All prior period amounts and disclosures are presented under Accounting Standards Codification Topic 840, Leases (“ASC 840”). The Company has revised its controls and processes to address the new lease standard and has completed the implementation and data input for our lease accounting software tool. The Company has elected the package of practical expedients, which, among other things, allows carry-forward of prior lease classifications under the prior standard. However, the Company has not elected to adopt the hindsight practical expedient and is therefore maintaining the lease terms previously determined under the prior lease standard. For all new and modified leases after adoption of the ASU, the Company has taken the component election allowing the Company to account for lease components together with non-lease components in the calculation of the lease asset and corresponding liability. Adoption of the new standard resulted in the recording of additional lease assets and lease liabilities on the unaudited condensed consolidated balance sheet. No cumulative-effect adjustment was recognized as the amount was not material, and the impact on the Company’s results of operations and cash flows was also not material. See Note 8 for additional disclosures. In February 2018, the FASB issued ASU 2018-02 (“ASU 2018-02”), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”). ASU 2018-02 provides entities the option to reclassify tax effects to retained earnings from AOCI which are impacted by the Tax Cuts and Jobs Act (“TCJA”). This ASU is effective for fiscal years beginning after December 15, 2018 but early adoption is permitted. The Company adopted this standard on December 31, 2018. The Company has a full valuation allowance for all tax benefits related to AOCI, and therefore, there are no tax effects to be reclassified to retained earnings.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts and the related estimated fair values of the Company’s long-term debt financial instruments not measured at fair value on a recurring basis at June 30, 2019 and December 30, 2018 are presented in Note 10. The carrying value of all other financial instruments, including cash equivalents, accounts receivable, accounts payable, accrued expenses, billings in excess of cost and earnings on uncompleted contracts, income taxes payable and short-term debt, approximated their estimated fair values at June 30, 2019 and December 30, 2018 due to the short-term nature of these instruments.
Net Income (Loss) Per Common Share	Net Income (Loss) per Common Share The Company calculates net income (loss) per share in accordance with FASB Accounting Standards Codification Topic 260, Earnings per Share (Topic 260). Under Topic 260, basic net income (loss) per common share attributable to the Kratos shareholders is calculated by dividing net income (loss) attributable to Kratos by the weighted-average number of common shares outstanding during the reporting period. Diluted net income (loss) per common share attributable to the Kratos shareholders reflects the effects of potentially dilutive securities. The dilutive impact of potentially dilutive common shares is determined by applying the treasury stock method.
