funding for general corporate purposes, if necessary. We had no borrowings through June 30, 2019 under the credit facilities. We believe that we currently meet all conditions set forth in the revolving credit agreements to borrow thereunder, and we are not aware of any conditions that would prevent us from borrowing part or all of the $10.3 billion available to us under the revolving credit agreements. See Note 10 of our Consolidated Financial Statements for a description of our short-term financing including credit facilities. Our investment portfolio does not contain any asset-backed securities with underlying collateral of sub-prime mortgages, alternative-A mortgages, sub-prime auto loans or sub-prime home equity loans, collateralized debt obligations, collateralized loan obligations, credit default swaps, derivatives, auction rate securities, structured investment vehicles or non-investment grade fixed-income securities. We own AAA rated senior tranches of fixed rate auto loan, credit card, equipment lease, and rate reduction receivables, secured predominantly by prime collateral. All collateral on asset-backed securities is performing as expected. In addition, we own senior debt directly issued by Federal Home Loan Banks and Federal Farm Credit Banks. Our client funds investment strategy is structured to allow us to average our way through an interest rate cycle by laddering the maturities of our investments out to five years (in the case of the extended portfolio) and out to ten years (in the case of the long portfolio). This investment strategy is supported by our short-term financing arrangements necessary to satisfy short-term funding requirements relating to client funds obligations.
