million and $70 million during fiscal 2015 and fiscal 2014, respectively. 

The instruments not included in the VaR are intercompany loans denominated in non-functional currencies, fixed interest rate Japanese Yen denominated debt, fixed interest rate U.S. Dollar denominated debt and interest rate swaps. Intercompany loans and related interest amounts are eliminated in consolidation. Furthermore, our non-functional currency intercompany loans are substantially hedged against foreign exchange risk through the use of forward contracts, which are included in the VaR calculation above. Therefore, we consider the interest rate and foreign currency market risks associated with our non-functional currency intercompany loans to be immaterial to our consolidated financial position, results from operations and cash flows. 

During the year ended May 31, 2015, we entered into a series of forward- starting interest rate swap agreements. A forward-starting interest rate swap is an agreement that effectively hedges the variability in future benchmark interest payments attributable to changes in interest rates on the forecasted issuance of fixed-rate debt. We entered into these forward-starting interest rate swaps in order to lock in fixed interest rates on our forecasted issuance of debt. These instruments were designated as cash flow hedges of the variability in the expected cash outflows of interest payments on future debt due to changes in benchmark interest rates. 

Details of third-party debt and interest rate swaps are provided in the table below. The table presents principal cash flows and related weighted average interest rates by expected maturity dates. Weighted average interest rates for the fixed rate swapped to floating rate debt reflect the effective interest rates at May 31, 2015.
