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 March 30, 2014 and for the three months ended March 31, 2013 and March 30, 2014 is unaudited. The condensed consolidated balance sheet as of December 29, 2013 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 United States (“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 29, 2013, included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission ("SEC") on March 12, 2014 (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.


(b)	Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries for which all inter-company transactions have been eliminated in consolidation.


(c)	Fiscal Year

The Company has a 52/53 week fiscal year ending on the last Sunday of the calendar year, with interim fiscal periods ending on the last Sunday of each calendar quarter. The three months ended March 31, 2013 and March 30, 2014 consisted of a 13-week period. There are 52 calendar weeks in the fiscal years ending on December 29, 2013 and December 28, 2014.

(d) Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. Such estimates include revenue recognition, allowance for doubtful accounts, warranties, inventory valuation, valuation of long-lived assets including identifiable intangibles and goodwill, accounting for income taxes including the related valuation allowance on the deferred tax asset and uncertain tax positions, contingencies and litigation, contingent acquisition consideration, stock-based compensation, losses on unused office space, and business combination purchase price allocations. In the future, the Company may realize actual results that differ from the current reported estimates. If the estimates that the Company has used change in the future, such changes could have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In accounting for our long-term contracts for production of products and services provided to the U.S. Government and provided to our PSS segment customers under fixed price contracts, we utilize both cost-to-cost and units delivered measures under the percentage-of-completion method of accounting in accordance with the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition.

Due to the size and nature of many of our contracts accounted for under the percentage-of-completion method of accounting, the estimation of total revenues and costs at completion is complicated and subject to many variables. For example, estimates are made regarding the length of time to complete a contract since costs also include expected increases in wages, prices for materials and allocated fixed costs. Similarly, assumptions are made regarding the future impact of our efficiency initiatives and cost reduction efforts. Incentives, awards or penalties related to performance on contracts are considered in estimating revenue and profit rates and are recorded when there is sufficient information to assess anticipated performance. Suppliers' assertions are also assessed and considered in estimating costs and profit rates.

The Company closely monitors the consistent application of its critical accounting policies and compliance with contract accounting. Business operations personnel conduct periodic contract status and performance reviews. Also, regular and recurring evaluations of contract cost, scheduling and technical matters are performed by management personnel who are independent from the business operations personnel performing work under the contract. When adjustments in estimated contract revenues or costs are required, any significant changes from prior estimates are included in earnings in the current period ("the cumulative catch-up method").

(e) Accounting Standards Updates

There have been no changes in the Company's significant accounting policies for the three months ended March 30, 2014 as compared to the significant accounting policies described in the Form 10-K.


(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 December 29, 2013 and March 30, 2014 are presented in Note 8. 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 December 29, 2013 and March 30, 2014 due to the short-term nature of these instruments.
