11. DERIVATIVE FINANCIAL INSTRUMENTS

As of August 31, 2015, the Company has interest rate swap agreements to hedge $155.0 million of its future interest commitments resulting from the Company’s Term Loan Facility, and to protect the Company from variability in cash flows attributable to changes in LIBOR interest rates. The purpose of entering into these swap agreements is to match the LIBOR floor in the swaps with the terms of the Term Loan Facility. Consistent with the terms of the Company’s Term Loan Facility, these swaps include a LIBOR floor of 1.25%. These swap agreements hedge a portion of contractual floating rate interest commitments through the expiration of the agreement in September of each year through 2016. As a result of these agreements, the LIBOR rate associated with the hedged amount of the Company’s indebtedness has been fixed at 1.77% until September 30, 2015.

Prior to October 1, 2014, the Company had swap agreements that hedged $240.0 million of its floating rate interest commitments at a weighted average fixed LIBOR rate of 1.67%. Effective October 1, 2014 through September 30, 2015, the Company has swap agreements that hedge $155.0 million of the Company’s floating rate interest commitments at a weighted average fixed LIBOR rate of 1.77%. Effective October 1, 2015 through September 30, 2016, the Company will have swap agreements to hedge $70.0 million of the Company’s floating rate interest commitments at a fixed LIBOR rate of 1.91%.

The Company designated the interest rate swap agreements as cash flow hedges. As cash flow hedges, unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. The interest rate swap agreements are highly correlated to the changes in interest rates to which the Company is exposed. Unrealized gains and losses on these swaps are designated as effective or ineffective. The effective portion of such gains or losses is recorded as a component of accumulated other comprehensive income or loss, while the ineffective portion of such gains or losses will be recorded as a component of interest expense. Future realized gains and losses in connection with each required interest payment will be reclassified from accumulated other comprehensive income or loss to interest expense.

The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in accumulated other comprehensive income or loss and are reclassified into interest expense in the same period the hedged item affects earnings. Due to the high degree of effectiveness between the hedging instruments and the underlying exposures being hedged, fluctuations in the value of the derivative instruments are generally offset by changes in the fair values or cash flows of the underlying exposures being hedged. The changes in the fair values of derivatives that do not qualify as effective are immediately recognized in earnings.

The gains and losses on derivative contracts that are reclassified from accumulated other comprehensive income or loss to current period earnings are included in the line item in which the hedged item is recorded in the same period the forecasted transaction affects earnings. As of August 31, 2015, approximately $0.5 million of the deferred net loss on derivative instruments accumulated in other comprehensive loss is expected to be reclassified as interest expense during the next twelve months. This expectation is based on the expected timing of the occurrence of the hedged forecasted transactions.

The fair values of the interest rate swap agreements are estimated using industry standard valuation models using market-based observable inputs, including interest rate curves (level 2). A summary of the recorded liabilities included in the consolidated balance sheets is as follows (in thousands):
