Debt Portfolio Management It is our policy to identify on a continuing basis the need for debt capital and evaluate the financial risks inherent in funding the Company with debt capital.
Reflecting the result of this ongoing review, the debt portfolio and hedging program are managed with the objectives and intent to (1) reduce funding risk with respect to borrowings made by us to preserve our access to debt capital and provide debt capital as required for funding and liquidity purposes, and (2) manage the aggregate interest rate risk and the debt portfolio in accordance with certain debt management parameters.
Interest Rate Management Contracts We enter into interest rate swaps to change the fixed/variable interest rate mix of our debt portfolio in order to maintain the percentage of fixed- and variable-rate debt within the parameters set by management.
In accordance with these parameters, the agreements are used to manage interest rate risks and costs inherent in our debt portfolio.
Our interest rate management portfolio generally consists of fixed-to-floating interest rate swaps (which are designated as fair value hedges), pre-issuance interest rate swaps and treasury locks (which hedge the interest rate risk associated with anticipated fixed-rate debt issuances and are designated as cash flow hedges), and floating-to-fixed interest rate swaps (which are designated as cash flow hedges).
At 30 September 2018, the outstanding interest rate swaps were denominated in U. S.  Dollars.
The notional amount of the interest rate swap agreements is equal to or less than the designated debt being hedged.
When interest rate swaps are used to hedge variable-rate debt, the indices of the swaps and the debt to which they are designated are the same.
It is our policy not to enter into any interest rate management contracts which lever a move in interest rates on a greater than oneto-one basis.
Cross Currency Interest Rate Swap Contracts We enter into cross currency interest rate swap contracts when our risk management function deems necessary.
These contracts may entail both the exchange of fixed- and floating-rate interest payments periodically over the life of the agreement and the exchange of one currency for another currency at inception and at a specified future date.
The contracts are used to hedge either certain net investments in foreign operations or nonfunctional currency cash flows related to intercompany loans.
The current cross currency interest rate swap portfolio consists of fixed-to-fixed swaps primarily between U. S.  Dollars and Chinese Renminbi, U. S.  Dollars and Chilean Pesos, and U. S.  Dollars and Indian Rupee.
The following table summarizes our outstanding interest rate management contracts and cross currency interest rate swaps:
