Line of Credit Facility [Abstract]
Lines Of Credit	2011 Credit Agreement On June 30, 2011, we entered into an unsecured senior credit facility (the “2011 Credit Agreement”) providing for a five-year term loan of $100.0 million and a revolving credit facility in the principal amount of up to $300.0 million. The borrowings all carry a variable interest rate based on LIBOR, prime, or a similar index, plus a margin (margin not to exceed a per annum rate of 1.75%). As of September 30, 2012, we had $180.0 million of principal borrowed under the revolving credit facility, $93.8 million of principal borrowed under the term loan, and borrowing availability of $120.0 million under the revolving credit facility. In September 2011, we entered into a new interest rate swap and an interest rate cap agreement. These interest rate hedges were deemed to be fully effective in accordance with ASC 815, “Derivatives and Hedging,” and, as such, unrealized gains and losses related to these derivatives are recorded as other comprehensive income. Principal in the amount of $100.0 million under the 2011 Credit Agreement has been hedged with an interest rate swap agreement and carries a fixed interest rate of 1.3% plus an applicable margin. Principal in the amount of $50.0 million has been hedged with an interest rate cap arrangement with an interest rate cap of 2.0% plus an applicable margin. As of September 30, 2012, our debt under the 2011 Credit Agreement, including the $100.0 million of principal hedged with an interest swap agreement, carried an average annualized interest rate of 1.6%. During the three months ended September 30, 2012, we made principal payments of $1.3 million on the term loan. The term loan scheduled repayments under the 2011 Credit Agreement increase over time from 5% of the principal due in the first year to 60% of the principal due in the last year. Additional Lines of Credit We have an unsecured line of credit with JP Morgan UK in the amount of $4.5 million that bears interest at an annual rate ranging between 2% and 4%. We entered into this line of credit to facilitate business transactions. At September 30, 2012, we had $4.5 million available under this line of credit. We have a cash pool facility with RBS Nederland, NV in the amount of 5.0 million Euros that bears interest at an annual rate ranging between 1.0% and 2.0%. We entered into this line of credit to facilitate business transactions. At September 30, 2012, we had 5.0 million Euros available under this line of credit. We have a cash pooling arrangement with RBS Nederland, NV. Pooling occurs when debit balances are offset against credit balances and the overall net position is used as a basis by the bank for calculating the overall pool interest amount. Each legal entity owned by us and party to this arrangement remains the owner of either a credit (deposit) or a debit (overdraft) balance. Therefore, interest income is earned by legal entities with credit balances, while interest expense is charged to legal entities with debit balances. Based on the pool’s aggregate balance, the bank then (1) recalculates the overall interest to be charged or earned, (2) compares this amount with the sum of previously charged/earned interest amounts per account and (3) additionally pays/charges the difference. The gross overdraft balance related to this pooling arrangement was $44.2 million and $63.4 million at September 30, 2012 and June 30, 2012, respectively, and was included in cash and cash equivalents.
