Defense contract audit agency completed cost audits |  |  |  | Contract costs on U.S. government contracts are subject to audit and review by the Defense Contracting Management Agency (DCMA), the Defense Contract Audit Agency (DCAA), and other U.S. government agencies, as well as negotiations with U.S. government representatives. The Company’s incurred cost audits by the DCAA have not been concluded for fiscal years 2016 and 2017. As of December 31, 2017, the DCAA had completed its incurred cost audit for fiscal year 2004 and approved the Company’s incurred cost claims for fiscal years 2005 through 2015 without further audit. Although the Company has recorded contract revenues subsequent to fiscal year 2015 based upon an estimate of costs that the Company believes will be approved upon final audit or review, the Company does not know the outcome of any ongoing or future audits or reviews and adjustments, and if future adjustments exceed the Company’s estimates, its profitability would be adversely affected. |  |

Description of new accounting pronouncements |  |  |  | In March 2016, the FASB issued ASU 2016-09, Compensation — Stock Compensation (ASC 718).

The new guidance became effective for the Company beginning in fiscal year 2018. The Company adopted this guidance in the first quarter of fiscal year 2018. On a prospective basis the Company recognizes excess tax benefits or deficiencies on vesting or settlement of awards as discrete items within income tax benefit or provision within net income (loss) and the related cash flows classified within operating activities.

It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new guidance will become effective for the Company beginning in fiscal year 2021, with early adoption permitted. The new guidance is required to be applied on a modified-retrospective basis. The Company is currently evaluating the impact of this standard on its consolidated financial statements and disclosures. |  |

Description of new accounting pronouncements |  |  |  | In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 improves the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP.

Description of new accounting pronouncements |  |  |  | In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to a customer. This guidance will replace most existing revenue recognition guidance and will be effective for the Company beginning in fiscal year 2019, including interim periods within that reporting period, based on the FASB decision in July 2015 (ASU 2015-14, Revenue from Contracts with Customers – Deferral of the Effective Date) to delay the effective date of the new revenue recognition standard by one year, but providing entities a choice to adopt the standard as of the original effective date. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing, which clarifies the implementation guidance on identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients, which provides practical expedient for contract modifications and clarification on assessing the collectability criterion, presentation of sales taxes, measurement date for non-cash consideration and completed contracts at transition. In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to ASC 606, Revenue from Contracts with Customers, which provides for correction or improvement to the guidance previously issued in ASU 2014-09. These standards permit the use of either the retrospective or cumulative effect transition method. The Company currently plans to adopt the standard in fiscal year 2019 using the “modified retrospective method.” Under that method, the Company will apply the rules to all contracts existing as of April 1, 2018, recognizing in beginning retained earnings an adjustment for the cumulative effect of the change and providing additional disclosures comparing results to previous accounting standards. Upon initial evaluation, the Company believes the key changes in the standard that impact its revenue recognition relate to the deferral of commissions in the Company’s satellite service segment, which are currently expensed as incurred under the current standard. The requirement to defer incremental contract acquisition costs and recognize them with the transfer of the related good or service will result in the recognition of a deferred charge on the Company’s consolidated balance sheet and corresponding impact to the Company’s consolidated statement of operations and comprehensive income (loss). |  |

Description of new accounting pronouncements |  |  |  | In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842). ASU 2016-02 requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets and eliminates certain real estate-specific provisions. In January 2018 the FASB issued ASU 2018-01, Leases (ASC 842). ASU 2018-01 permits an entity to elect an optional transition practical expedient to not evaluate land easements that exist or expired before the entity’s adoption of ASC 842 and that were not previously accounted for as leases under ASC 840. The new guidance will become effective for the Company beginning in the first quarter of fiscal year 2020, with early adoption permitted. ASU 2016-02 will be adopted on a modified retrospective transition basis for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the impact of this standard on its consolidated financial statements and disclosures. |  |

Description of new accounting pronouncements |  |  |  | In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (ASC 230). ASU 2016-15 makes eight targeted changes to how companies present and classify certain cash receipts and cash payments in the statement of cash flows. The new standard will become effective for the Company beginning in fiscal year 2019, with early adoption permitted. The new standard will require adoption on a retrospective basis unless it is impracticable to apply, in which case the Company would be required to apply the amendments prospectively as of the earliest date practicable. The Company early adopted the guidance on a retrospective basis in the second quarter of fiscal year 2018 and as a result cash payments for debt prepayment and extinguishment are classified as cash outflows for financing activities. Otherwise the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements and disclosures. |  |

Total shareholder return performance stock options description |  |  |  | During the third quarter of fiscal year 2018, the Company began granting total shareholder return (TSR) performance stock options to executive officers under the 1996 Equity Participation Plan. The number of shares of TSR performance stock options that will become eligible to vest based on the time-based vesting schedule described below is based on a comparison over a four-year performance period of the Company’s TSR to the TSR of the companies included in the S&P Mid Cap 400 Index. The number of options that may become vested and exercisable will range from 0% to 175% of the target number of options based on the Company’s relative TSR ranking for the performance period. The Company estimates the fair value of TSR performance stock options at the grant date using a Monte Carlo simulation. The Company’s TSR performance stock options that become eligible to vest based on the Company’s TSR performance during the performance period are also subject to a four-year time-based vesting schedule and a six year contractual term. The options must be vested under both the time-based vesting schedule and the performance-based vesting conditions in order to become exercisable. Expense for TSR performance stock options that vest is recognized regardless of the actual TSR outcome achieved and is recognized on a graded-vesting basis |  |
