•

Definite contracts call for the performance of specified services or the delivery of specified products. The U.S. government procures services and solutions through single award, definite contracts that specify the scope of services that will be delivered and identify the contractor that will provide the specified services. When an agency recognizes a need for services or products, it develops an acquisition plan, which details the means by which it will procure those services or products. During the acquisition process, the agency may release a request for information to determine if qualified bidders exist, a draft request for a proposal to allow the industry to comment on the scope of work and acquisition strategy, and finally a formal request for a proposal. Following the evaluation of submitted proposals, the agency will award the contract to the winning bidder.

(1)

Basic earnings per share for the Company has been computed using the weighted average number of shares of Class A Common Stock, Class B Non- Voting Common Stock, and Class C Restricted Common Stock outstanding during the period. The Company’s diluted earnings per share has been computed using the weighted average number of shares of Class A Common Stock, Class B Non-Voting Common Stock, and Class C Restricted Common Stock including the dilutive effect of outstanding common stock options and other stock-based awards. For the purposes of calculating basic and diluted earnings per share, the Company has utilized the two class method, given non-forfeitable dividends declared on unvested Class A Restricted Common Stock. The weighted average number of Class E Special Voting Common Stock has not been included in the calculation of either basic earnings per share or diluted earnings per share due to the terms of such common stock.

Item 7.	Management’s Discussion and Analysis of Financial Condition and Results of Operations

---

•

"Revenue, Excluding Billable Expenses" represents revenue less billable expenses. We use Revenue, Excluding Billable Expenses because it provides management useful information about the Company's operating performance by excluding the impact of costs that are not indicative of the level of productivity of our consulting staff headcount and our overall direct labor, which management believes provides useful information to our investors about our core operations.

•

"Adjusted Operating Income" represents operating income before: (i) adjustments related to the amortization of intangible assets resulting from the acquisition of our Company by The Carlyle Group, and (ii) transaction costs, fees, losses, and expenses, including fees associated with debt prepayments. We prepare Adjusted Operating Income to eliminate the impact of items we do not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary, or non-recurring nature or because they result from an event of a similar nature.

•

"Adjusted EBITDA" represents net income before income taxes, net interest and other expense and depreciation and amortization and before certain other items, including transaction costs, fees, losses, and expenses, including fees associated with debt prepayments. “Adjusted EBITDA Margin” is calculated as Adjusted EBITDA divided by revenue. The Company prepares Adjusted EBITDA and Adjusted EBITDA Margin to eliminate the impact of items it does not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary or non-recurring nature or because they result from an event of a similar nature.

•

"Adjusted Net Income" represents net income before: (i) adjustments related to the amortization of intangible assets resulting from the acquisition of our Company by The Carlyle Group,, (ii) transaction costs, fees, losses, and expenses, including fees associated with debt prepayments, (iii) amortization or write-off of debt issuance costs and write-off of original issue discount, and (iv) release of income tax reserves, in each case net of the tax effect where appropriate calculated using an assumed effective tax rate. We prepare Adjusted Net Income to eliminate the impact of items, net of tax, we do not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary, or non-recurring nature or because they result from an event of a similar nature.

---

•	"Adjusted Diluted EPS" represents diluted EPS calculated using Adjusted Net Income as opposed to net income. Additionally, Adjusted Diluted EPS does not contemplate any adjustments to net income as required under the two-class method as disclosed in the footnotes to the consolidated financial statements.

•	"Free Cash Flow" represents the net cash generated from operating activities less the impact of purchases of property and equipment.

---

(a)	Reflects amortization of intangible assets resulting from the acquisition of our Company by The Carlyle Group.

(b)	Fiscal 2017 reflects debt refinancing costs incurred in connection with the refinancing transaction consummated on July 13, 2016. Fiscal 2015 reflects debt refinancing costs incurred in connection with the refinancing transaction consummated on May 7, 2014.

(c)	Reflects the combination of Interest expense and Other income (expense), net from the consolidated income statement.

(d)	Release of pre-acquisition income tax reserves assumed by the Company in connection with the acquisition of our Company by The Carlyle Group.

---

•

uncertainty around the timing, extent, nature and effect of Congressional and other U.S. government actions to address budgetary constraints, caps on the discretionary budget for defense and non-defense departments and agencies, as established by the Bipartisan Budget Control Act of 2011 and subsequently adjusted by the American Tax Payer Relief Act of 2012, the Bipartisan Budget Act of 2013 and the Bipartisan Budget Act of 2015, and the ability of Congress to determine how to allocate the available budget authority and pass appropriations bills to fund both U.S. government departments and agencies that are, and those that are not, subject to the caps.

•	budget deficits and the growing U.S. national debt increasing pressure on the U.S. government to reduce federal spending across all federal agencies together with associated uncertainty about the size and timing of those reductions;

•

cost cutting and efficiency initiatives, current and future budget restrictions, continued implementation of Congressionally mandated automatic spending cuts and other efforts to reduce U.S. government spending, could cause clients to reduce or delay funding for orders for services or invest appropriated funds on a less consistent or rapid basis or not at all, particularly when considering long-term initiatives and in light of uncertainty around Congressional efforts to approve funding of the U.S. government and to craft a long-term agreement on the U.S. government's ability to incur indebtedness in excess of its current limits and generally in the current political environment, there is a risk that clients will not issue task orders in sufficient volume to reach current contract ceilings, alter historical patterns of contract awards, including the typical increase in the award of task orders or completion of other contract actions by the U.S. government in the period before the end of the U.S. government's fiscal year on September 30, delay requests for new proposals and contract awards, rely on short-term extensions and funding of current contracts, or reduce staffing levels and hours of operation;

•	delays in the completion of future U.S. government’s budget processes, which have in the past and could in the future delay procurement of the products, services, and solutions we provide;

•

changes in the relative mix of overall U.S. government spending and areas of spending growth, with lower spending on homeland security, intelligence and defense-related programs as certain overseas operations end, and continued increased spending on cyber-security, Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR), advanced analytics, technology integration and healthcare;

•

legislative and regulatory changes to limitations on the amount of allowable executive compensation permitted under flexibly priced contracts following adoption of interim rules adopted by federal agencies implementing a section of the Bipartisan Budget Act of 2013, which substantially further reduce the amount of allowable executive compensation under these contracts and extend these limitations to a larger segment of our executives and our entire contract base;

•	efforts by the U.S. government to address organizational conflicts of interest and related issues and the impact of those efforts on us and our competitors;

•	increased audit, review, investigation and general scrutiny by U.S. government agencies of government contractors' performance under U.S. government contracts and compliance with the terms of those contracts and applicable laws;

---

•	the federal focus on refining the definition of “inherently governmental” work, including proposals to limit contractor access to sensitive or classified information and work assignments, which will continue to drive pockets of insourcing in various agencies, particularly in the intelligence market;

•	negative publicity and increased scrutiny of government contractors in general, including us, relating to U.S. government expenditures for contractor services and incidents involving the mishandling of sensitive or classified information;

•	U.S. government agencies awarding contracts on a technically acceptable/lowest cost basis, which could have a negative impact on our ability to win certain contracts;

•	increased competition from other government contractors and market entrants seeking to take advantage of certain of the trends identified above, and industry trend towards consolidation, which may result in the emergence of companies that are better able to compete against us;

•	cost cutting and efficiency and effectiveness efforts by U.S. civilian agencies with a focus on increased use of performance measurement, “program integrity” efforts to reduce waste, fraud and abuse in entitlement programs, and renewed focus on improving procurement practices for and interagency use of IT services, including through the use of cloud based options and data center consolidation;

•	restrictions by the U.S. government on the ability of federal agencies to use lead system integrators, in response to cost, schedule and performance problems with large defense acquisition programs where contractors were performing the lead system integrator role;

•	increasingly complex requirements of the Department of Defense and the U.S. intelligence community, including cyber-security, managing federal health care cost growth and focus on reforming existing government regulation of various sectors of the economy, such as financial regulation and healthcare;

•	increasing small business regulations across the Department of Defense and civilian agency clients continue to gain traction-agencies are required to meet high small business set aside targets, and large business prime contractors are required to subcontract in accordance with considerable small business participation goals necessary for contract award; and

•	changes in agency and mission priorities anticipated in the Department of Defense and Civilian agency landscape with the presidential and administration transition.

•

Cost-Reimbursable Contracts. Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract, up to a ceiling based on the amount that has been funded, plus a fee. As we increase or decrease our spending on allowable costs, our revenue generated on cost-reimbursable contracts will increase, up to the ceiling and funded amounts, or decrease, respectively. We generate revenue under two general types of cost-reimbursable contracts: cost-plus-fixed-fee and cost-plus-award-fee, both of which reimburse allowable costs and provide

---

•

Time-and-Materials Contracts. Under a time-and-materials contract, we are paid a fixed hourly rate for each direct labor hour expended, and we are reimbursed for billable material costs and billable out-of-pocket expenses inclusive of allocable indirect costs. To the extent our actual direct labor including allocated indirect costs, and associated billable expenses decrease or increase in relation to the fixed hourly billing rates provided in the contract, we will generate more or less profit, respectively, or could incur a loss.

•

Fixed-Price Contracts. Under a fixed-price contract, we agree to perform the specified work for a pre-determined price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss. Some fixed-price contracts have a performance-based component, pursuant to which we can earn incentive payments or incur financial penalties based on our performance. Fixed-price level of effort contracts require us to provide a specified level of effort (i.e., labor hours), over a stated period of time, for a fixed price.

(1)	Includes both cost-plus-fixed-fee and cost-plus-award-fee contracts.

(2)	Includes fixed-price level of effort contracts.

•	Funded Backlog. Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts.

•	Unfunded Backlog. Unfunded backlog represents the revenue value of orders for services under existing contracts for which funding has not been appropriated or otherwise authorized.

•	Priced Options. Priced contract options represent 100% of the revenue value of all future contract option periods under existing contracts that may be exercised at our clients’ option and for which funding has not been appropriated or otherwise authorized.

(1)	Amounts as of fiscal 2015 reflect a reduction by management to the revenue value of orders for services under one then-existing single award IDIQ contract the Company had for several years, based on an established pattern of funding under this contract by the U.S. government.
