5. Long-term Debt

Long-term debt consisted of the following (in thousands):

Bank Credit Facility

The Company has a $750.0 million credit facility (the Credit Facility), which consists of a $600.0 million revolving credit facility (the Revolving Facility) and a $150.0 million term loan (the Term Loan). The Revolving Facility has subfacilities of $50.0 million for same-day swing line loan borrowings and $25.0 million for stand-by letters of credit. The Credit Facility was entered into on October 21, 2010 and replaced the Company's then outstanding term loan and revolving credit facility.

Subsequent to entering into the Credit Facility, CACI amended the Credit Facility to increase its ability to do share repurchases, modify the margins applicable to the determination of the interest rate and the unused fees under the Credit Agreement, extend the maturity date of the Credit Facility from October 21, 2015 to November 18, 2016, and increase from $200.0 million to $300.0 million the permitted aggregate amount of incremental facilities that may be added by amendment to the Credit Facility.

The Revolving Facility is a secured facility that permits continually renewable borrowings of up to $600.0 million. As of December 31, 2011, the Company had $185.0 million outstanding under the Revolving Facility and no outstanding letters of credit. The Company pays a quarterly facility fee for the unused portion of the Revolving Facility.

The Term Loan is a five-year secured facility under which principal payments are due in quarterly installments of $1.9 million through September 30, 2015 and $3.8 million thereafter until September 30, 2016, with the balance due in full on November 18, 2016.

At any time and so long as no default has occurred, the Company has the right to increase the Term Loan or Revolving Facility in an aggregate principal amount of up to $300.0 million with applicable lender approvals. The Credit Facility is available to refinance existing indebtedness and for general corporate purposes, including working capital expenses and capital expenditures.

The interest rates applicable to loans under the Credit Facility are floating interest rates that, at the Company's option, equal a base rate or a Eurodollar rate plus, in each case, an applicable margin based upon the Company's consolidated total leverage ratio. As of December 31, 2011, the effective interest rate, excluding the effect of amortization of debt financing costs, for the outstanding borrowings under the Credit Facility was 1.78 percent.

The Credit Facility requires the Company to comply with certain financial covenants, including a maximum senior secured leverage ratio, a maximum total leverage ratio and a minimum fixed charge coverage ratio. The Credit Facility also includes customary negative covenants restricting or limiting the Company's ability to guarantee or incur additional indebtedness, grant liens or other security interests to third parties, make loans or investments, transfer assets, declare dividends or redeem or repurchase capital stock or make other distributions, prepay subordinated indebtedness and engage in mergers, acquisitions or other business combinations, in each case except as expressly permitted under the Credit Facility. Since the inception of the Credit Facility, the Company has been in compliance with all of the financial covenants. A majority of the Company's assets serve as collateral under the Credit Facility.

The Company capitalized $7.3 million of debt issuance costs associated with the origination and amendment of the Credit Facility. All debt issuance costs are being amortized from the date incurred to the expiration date of the Credit Facility. The unamortized balance of $5.6 million at December 31, 2011 is included in other assets.

Convertible Notes Payable

Effective May 16, 2007, the Company issued the Notes in a private placement. The Notes were issued at par value and are subordinate to the Company's senior secured debt. Interest on the Notes is payable on May 1 and November 1 of each year.

Holders may convert their notes at a conversion rate of 18.2989 shares of CACI common stock for each $1,000 of note principal (an initial conversion price of $54.65 per share) under the following circumstances: 1) if the last reported sale price of CACI stock is greater than or equal to 130 percent of the applicable conversion price for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; 2) during the five consecutive business day period immediately after any ten consecutive trading day period (the note measurement period) in which the average of the trading price per $1,000 principal amount of convertible note was equal to or less than 97 percent of the average product of the closing price of a share of the Company's common stock and the conversion rate of each date during the note measurement period; 3) upon the occurrence of certain corporate events constituting a fundamental change, as defined in the indenture governing the Notes; or 4) during the last three-month period prior to maturity. CACI is required to satisfy 100 percent of the principal amount of these notes solely in cash, with any amounts above the principal amount to be satisfied in common stock. As of December 31, 2011, none of the conditions permitting conversion of the Notes had been satisfied.

In the event of a fundamental change, as defined in the indenture governing the Notes, holders may require the Company to repurchase the Notes at a price equal to the principal amount plus any accrued interest. Also, if certain fundamental changes occur prior to maturity, the Company will in certain circumstances increase the conversion rate by a number of additional shares of common stock or, in lieu thereof, the Company may in certain circumstances elect to adjust the conversion rate and related conversion obligation so that these notes are convertible into shares of the acquiring or surviving company. The Company is not permitted to redeem the Notes.

The Company separately accounts for the liability and the equity (conversion option) components of the Notes and recognizes interest expense on the Notes using an interest rate in effect for comparable debt instruments that do not contain conversion features. The effective interest rate for the Notes excluding the conversion option was determined to be 6.9 percent.

The fair value of the liability component of the Notes was calculated to be $221.9 million at May 16, 2007, the date of issuance. The excess of the $300.0 million of gross proceeds over the $221.9 million fair value of the liability component, or $78.1 million, represents the fair value of the equity component, which was recorded, net of income tax effect, as additional paid-in capital within shareholders' equity. This $78.1 million difference represents a debt discount that is amortized over the seven-year term of the Notes as a non-cash component of interest expense. For the three and six months ended December 31, 2011 and 2010, the components of interest expense related to the Notes were as follows (in thousands):

The fair value of the Notes as of December 31, 2011 was $354.0 million based on quoted market values.

The contingently issuable shares that may result from the conversion of the Notes were included in CACI's diluted share count for the three and six month periods ended December 31, 2011 because CACI's average stock price for those periods was above the conversion price of $54.65 per share. The contingently issuable shares were not included in CACI's diluted share count for the three and six month periods ended December 31, 2010 because CACI's average stock price was below the conversion price during those periods (see Note 8). Of total debt issuance costs of $7.8 million, $5.8 million is being amortized to interest expense over seven years. The remaining $2.0 million of debt issuance costs attributable to the embedded conversion option was recorded in additional paid-in capital. Upon closing of the sale of the Notes, $45.5 million of the net proceeds was used to concurrently repurchase one million shares of CACI's common stock.

In connection with the issuance of the Notes, the Company purchased in a private transaction at a cost of $84.4 million call options (the Call Options) to purchase approximately 5.5 million shares of its common stock at a price equal to the conversion price of $54.65 per share. The cost of the Call Options was recorded as a reduction of additional paid-in capital. The Call Options allow CACI to receive shares of its common stock from the counterparties equal to the amount of common stock related to the excess conversion value that CACI would pay the holders of the Notes upon conversion.

For income tax reporting purposes, the Notes and the Call Options are integrated. This created an original issue discount for income tax reporting purposes, and therefore the cost of the Call Options is being accounted for as interest expense over the term of the Notes for income tax reporting purposes. The associated income tax benefit of $32.8 million to be realized for income tax reporting purposes over the term of the Notes was recorded as an increase in additional paid-in capital and a long-term deferred tax asset. The majority of this deferred tax asset is offset in the Company's balance sheet by the $30.7 million deferred tax liability associated with the non-cash interest expense to be recorded for financial reporting purposes.

In addition, the Company sold warrants (the Warrants) to issue approximately 5.5 million shares of CACI common stock at an exercise price of $68.31 per share. The proceeds from the sale of the Warrants totaled $56.5 million and were recorded as an increase to additional paid-in capital.

On a combined basis, the Call Options and the Warrants are intended to reduce the potential dilution of CACI's common stock in the event that the Notes are converted by effectively increasing the conversion price of these notes from $54.65 to $68.31. The Call Options are anti-dilutive and are therefore excluded from the calculation of diluted shares outstanding. The Warrants will result in additional diluted shares outstanding if CACI's average common stock price exceeds $68.31. The Call Options and the Warrants are separate and legally distinct instruments that bind CACI and the counterparties and have no binding effect on the holders of the Notes.

JV Bank Credit Facility

eVenture Technologies LLC (eVentures), a joint venture between the Company and ActioNet, Inc., entered into a $1.5 million revolving credit facility (the JV Facility). The JV Facility was a four-year, guaranteed facility that permitted continuously renewable borrowings of up to $1.5 million with an expiration date of the earliest of September 14, 2011; the date of any restatement, refinancing, or replacement of the Credit Facility without the lender acting as the sole and exclusive administrative agent; or termination of the Credit Facility. The JV Facility expired on September 14, 2011. eVentures had no borrowings outstanding under the JV Facility during the six months ended December 31, 2011.

7. Stock-Based Compensation

Stock-based compensation expense recognized, together with the income tax benefits recognized, is as follows (in thousands):

Under the terms of its 2006 Stock Incentive Plan (the 2006 Plan), the Company may issue, among others, non-qualified stock options, restricted stock, RSUs, SSARs, and performance awards, collectively referred to herein as equity instruments. During the periods presented, all equity instrument grants were made in the form of RSUs. Other than performance-based RSUs which contain a market-based element, the fair value of RSU grants were determined based on the closing price of a share of the Company's common stock on the date of grant. The fair value of RSUs with market-based vesting features was also measured on the grant date, but was done so using a binomial lattice model.

Annual grants under the 2006 Plan are generally made to the Company's key employees during the first quarter of the Company's fiscal year and to members of the Company's Board of Directors during the second quarter of the Company's fiscal year. With the approval of its Chief Executive Officer, the Company also issues equity instruments to strategic new hires and to employees who have demonstrated superior performance. In September 2011, the Company made its annual grant to its key employees consisting of 721,540 Performance Restricted Stock Units (PRSUs), representing the maximum amount which could be earned. The PRSUs are subject to both performance and market conditions. No PRSUs will be earned if the Net After Tax Profit for the fiscal year ending June 30, 2012 is less than the Net After Tax Profit for the fiscal year ended June 30, 2011. The number of PRSUs earned by the grantee is dependent on the increase or decrease of the 90 calendar day average price per share of common stock of the Company for the period ended September 1, 2011 compared to the 90 calendar day average price per share of common stock of the Company for the period ending September 1, 2012. In addition to the performance and market conditions, there is a service vesting condition which stipulates that 50 percent of the award will vest on the third anniversary of the grant date and 50 percent of the award will vest on the fourth anniversary of the grant date, in both cases dependent upon continuing service by the grantee as an employee of the Company, unless the grantee is eligible for earlier vesting upon retirement, as defined.

The total number of shares authorized by shareholders for grants under the 2006 Plan and its predecessor plan is 12,450,000 as of December 31, 2011. The aggregate number of grants that may be made may exceed this approved amount as forfeited SSARs, stock options, restricted stock and RSUs, and vested but unexercised SSARs and stock options that expire, become available for future grants. As of December 31, 2011, cumulative grants of 12,256,571 equity instruments underlying the shares authorized have been awarded, and 2,514,143 of these instruments have been forfeited.

Activity related to SSARs/non-qualified stock options and RSUs/restricted shares issued under the 2006 Plan during the six months ended December 31, 2011 is as follows:

As of December 31, 2011, there was $2.1 million of total unrecognized compensation cost related to SSARs and stock options scheduled to be recognized over a weighted average period of 1.2 years, and $29.7 million of total unrecognized compensation cost related to restricted shares and RSUs scheduled to be recognized over a weighted-average period of 2.6 years.

8. Earnings Per Share

ASC 260, Earnings Per Share (ASC 260), requires dual presentation of basic and diluted earnings per share on the face of the income statement. Basic earnings per share exclude dilution and are computed by dividing income by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock but not securities that are anti-dilutive, including stock options and SSARs with an exercise price greater than the average market price of the Company's common stock. Using the treasury stock method, diluted earnings per share include the incremental effect of SSARs, stock options, restricted shares, and those RSUs that are no longer subject to a market or performance condition. The total number of weighted-average common stock equivalents excluded from the diluted per share computations due to their anti-dilutive effects were 0.8 million and 0.9 million for the three months ended December 31, 2011 and 2010, respectively, and 2.2 million for both the six months ended December 31, 2011 and 2010. The PRSUs granted in September 2011 are excluded from the calculation of diluted earnings per share as the underlying shares are considered to be contingently issuable shares. These shares will be included in the calculation of diluted earnings per share beginning in the first reporting period in which the performance metric is achieved. The shares underlying the Notes were included in the computation of diluted earnings per share for the three and six months ended December 31, 2011 because the average share price was above the conversion price during those periods. The shares underlying the Notes were not included in the computation of diluted earnings per share for the three and six month periods ended December 31, 2010 because the conversion price of $54.65 exceeded the average share price during those periods. The Warrants were excluded from the computation of diluted earnings per share during all periods presented because the Warrants' exercise price of $68.31 was greater than the average market price of a share of Company common stock during the three and six month periods ended December 31, 2011 and 2010. The chart below shows the calculation of basic and diluted earnings per share (in thousands, except per share amounts):

On August 29, 2011, we entered into an accelerated share repurchase agreement with Bank of America N.A. (BofA), under which we paid $209.7 million for 4 million shares of our common stock. Our effective per share purchase price will be based generally on the average of the daily volume weighted average prices per share of our common stock, less a discount, calculated during an averaging period which began August 25, 2011 and will last up to eleven months.

The total amount ultimately paid for these shares will not be known until the averaging period ends and a final settlement occurs. Upon final settlement, we will either receive a settlement amount or be required to remit a settlement amount, in cash or common stock, at our option. We recorded the $209.7 million payment to BofA as treasury stock in our consolidated balance sheet as of December 31, 2011.

Shares outstanding during the three and six months ended December 31, 2011, reflect the repurchase of shares of CACI's common stock under the accelerated share repurchase agreement described above and other share repurchase programs approved by the Company's Board of Directors. Shares outstanding during the three and six months ended December 31, 2010 reflect the repurchase of shares under other approved share repurchase programs.

10. Business Segment Information

The Company reports operating results and financial data in two segments: domestic operations and international operations. Domestic operations provide professional services and information technology solutions to its customers. Its customers are primarily U.S. federal government agencies. The Company does not measure revenue or profit by its major service offerings, either for internal management or external financial reporting purposes, as it would be impractical to do so. In many cases more than one offering is provided under a single contract, to a single customer, or by a single employee or group of employees, and segregating the costs of the service offerings in situations for which it is not required would be difficult and costly. The Company also serves customers in the commercial and state and local government sectors and, from time to time, serves a number of agencies of foreign governments. The Company places employees in locations around the world in support of its clients. International operations offer services to both commercial and non-U.S. government customers primarily through the Company's data information and knowledge management services, business systems solutions, and enterprise IT and network services lines of business. The Company evaluates the performance of its operating segments based on net income. Summarized financial information concerning the Company's reportable segments is as follows (in thousands):

11. Fair Value of Financial Instruments

ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability between market participants in an orderly transaction. The market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity for the asset or liability is known as the principal market. When no principal market exists, the most advantageous market is used. This is the market in which the reporting entity would sell the asset or transfer the liability with the price that maximizes the amount that would be received or minimizes the amount that would be paid. Fair value is based on assumptions market participants would make in pricing the asset or liability. Generally, fair value is based on observable quoted market prices or derived from observable market data when such market prices or data are available. When such prices or inputs are not available, the reporting entity should use valuation models.

The Company's financial assets and liabilities recorded at fair value on a recurring basis are categorized based on the priority of the inputs used to measure fair value. The inputs used in measuring fair value are categorized into three levels, as follows:

– Level 1 Inputs – unadjusted quoted prices in active markets for identical assets or liabilities.

– Level 2 Inputs – unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data.

– Level 3 Inputs – amounts derived from valuation models in which unobservable inputs reflect the reporting entity's own assumptions about the assumptions of market participants that would be used in pricing the asset or liability.

As of December 31, 2011, the Company's financial instruments measured at fair value included non-corporate owned life insurance (COLI) money market investments and mutual funds held in the Company's supplemental retirement savings plan (the Supplemental Savings Plan) and contingent consideration in connection with business combinations completed during the year ended June 30, 2010. The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2011 and June 30, 2011, and the level they fall within the fair value hierarchy (in thousands):

Changes in the fair value of the assets held in connection with the Supplemental Savings Plan are recorded in indirect costs and selling expenses.

All three acquisitions completed during the year ended June 30, 2010 contained provisions requiring that the Company pay contingent consideration in the event the acquired businesses achieved certain specified earnings results during the two year periods subsequent to each acquisition. The Company determined the fair value of the contingent consideration as of each acquisition date using a valuation model which included the evaluation of all possible outcomes and the application of an appropriate discount rate. At the end of each reporting period, the fair value of the contingent consideration is remeasured and any changes are recorded in indirect costs and selling expenses. During the three and six months ended December 31, 2011, this remeasurement resulted in a $0.2 million increase and a $0.5 million decrease, respectively in the liability recorded. For the three and six months ended December 31, 2010, this remeasurement resulted in a $0.6 million decrease and a $1.1 million increase, respectively, in the liability recorded. During the three month period ended December 31, 2011, payments of $20.3 million were made in settlement of earned contingent consideration in connection with two of the acquisitions.
