Long-Term Debt	10. Long-Term Debt On December 19, 2018, the Company entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) with a syndicate of banks and Wells Fargo Bank, National Association as administrative agent to among other things, provide for enhanced financial flexibility. The Credit Agreement provides for, among other things: (a) a $650.0 million five-year senior secured revolving credit facility (the “Revolver”) and (b) certain customary affirmative and negative covenants, including a maximum consolidated total leverage ratio (as defined below) and a minimum interest coverage ratio. The Credit Agreement permits payment of dividends to stockholders and share repurchases so long as the pro forma leverage ratio is no greater than 3.25 to 1.00, and the pro forma domestic liquidity is at least $50.0 million. The Company drew down $226.9 million on the Revolver and used the proceeds to pay-off the term loan that was outstanding as of December 19, 2018. The payoff of the old credit facility and draw down on the new Revolver is considered a debt modification and therefore, the previously incurred unamortized and current debt issuance costs will be amortized over the life of the new issuance. At the Company’s option, loans issued under the Credit Agreement will bear interest at either LIBOR or an alternate base rate, in each case plus the applicable interest rate margin. The interest rate applicable to loans outstanding under the Credit Agreement may fluctuate between LIBOR plus 1.25% per annum to LIBOR plus 2.00% per annum, in the case of LIBOR borrowings (or between the alternate base rate plus 0.25% per annum and the alternate base rate plus 1.00% per annum, in the alternative), based upon the Company’s total funded debt to Adjusted EBITDA ratio (as set forth in the Credit Agreement, the “consolidated leverage ratio”) at such time. In addition, the Company will be required to pay to the lenders a quarterly commitment fee ranging from 0.20% to 0.35% per annum on the average daily unused amount of the Revolver, based upon the Company’s consolidated leverage ratio at such time, and fees relating to the issuance of letters of credit. During the three and nine months ended January 31, 2019, the average interest rate on our long-term debt arrangements were 3.64% and 3.42%, respectively. During the three and nine months ended January 31, 2018, the average interest rate on our previous term loan was 2.65% and 2.49%, respectively. The Revolver matures on December 19, 2023 and any unpaid principal balance is payable on this date. The Revolver also may be prepaid and terminated early by the Company at any time without premium or penalty (subject to customary LIBOR breakage fees). As of January 31, 2019, $226.9 million was outstanding under the Revolver compared to $238.9 million as of April 30, 2018, under the previous term loan. The unamortized debt issuance costs associated with the long-term debt were $4.2 million and $2.7 million as of January 31, 2019 and April 30, 2018, respectively. The fair value of the Company’s Revolver is based on borrowing rates currently required of loans with similar terms, maturity and credit risk. The carrying amount of the Revolver approximates fair value because the base interest rate charged varies with market conditions and the credit spread is commensurate with current market spreads for issuers of similar risk. The fair value of the Revolver is classified as a Level 2 liability in the fair value hierarchy. As of January 31, 2019, the Company was in compliance with its debt covenants. The Company had a total of $420.2 million available under the Revolver after the Company drew down $226.9 million and after $2.9 million of standby letters of credit were issued as of January 31, 2019. As of April 30, 2018, the Company had no borrowings under its previous revolver. The Company had a total of $122.1 million available under the previous revolver after $2.9 million of standby letters of credit were issued as of April 30, 2018. The Company had a total of $10.4 million and $7.4 million of standby letters with other financial institutions as of January 31, 2019 and April 30, 2018, respectively. The standby letters of credits were generally issued as a result of entering into office premise leases.
