We seek to structure our liabilities conservatively to reduce refinancing risk and the risk that we may redeem or repurchase certain of our borrowings prior to their contractual maturity.
We fund a substantial portion of our inventory on a secured basis, which we believe provides Goldman Sachs with a more stable source of liquidity than unsecured financing, as it is less sensitive to changes in our credit due to the underlying collateral. We recognize that the terms or availability of secured funding, particularly overnight funding, can deteriorate in a difficult environment. To help mitigate this risk, we raise the majority of our funding for durations longer than overnight. We seek longer durations for secured funding collateralized by lower quality assets, as we believe these funding transactions may pose greater refinancing risk. The weighted average life of our secured funding, excluding funding collateralized by highly liquid securities, such as U.S., French, German, United Kingdom and Japanese government bonds, and U.S. agency securities, exceeded 90 days as of May 2008.
Our liquidity also depends to an important degree on the stability of our short-term unsecured financing base. Accordingly, we prefer the use of promissory notes (in which Goldman Sachs does not make a market) over commercial paper, which we may repurchase prior to maturity through the ordinary course of business as a market maker. As of May 2008 and November 2007, our unsecured short-term borrowings, including the current portion of unsecured long-term borrowings, were $71.18 billion and $71.56 billion, respectively. See Note 4 to the condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for further information regarding our unsecured short-term borrowings.
We issue long-term borrowings as a source of total capital in order to meet our long-term financing requirements. Please see our quarterly unsecured long-term borrowings maturity profile through 2014.
The weighted average maturity of our unsecured long-term borrowings as of May 2008 was approximately eight years. To mitigate refinancing risk, we have created internal guidelines on the principal amount of debt maturing on any one day or during any week or year. We swap a substantial portion of our long-term borrowings into U.S. dollar obligations with short-term floating interest rates in order to minimize our exposure to interest rates and foreign exchange movements.
We issue substantially all of our unsecured debt without provisions that would, based solely upon an adverse change in our credit ratings, financial ratios, earnings, cash flows or stock price, trigger a requirement for an early payment, collateral support, change in terms, acceleration of maturity or the creation of an additional financial obligation.
We seek to maintain broad and diversified funding sources globally for both secured and unsecured funding. We make extensive use of the repurchase agreement and securities lending markets, as well as other secured funding markets. In addition, we issue debt through syndicated U.S. registered offerings, U.S. registered and 144A medium-term note programs, offshore medium-term note offerings and other bond offerings, U.S. and non-U.S. commercial paper and promissory note issuances, and other methods. We also arrange for letters of credit to be issued on our behalf.
We benefit from distributing our debt issuances through our own sales force to a large, diverse global creditor base and we believe that our relationships with our creditors are critical to our liquidity. Our creditors include banks, governments, securities lenders, pension funds, insurance companies and mutual funds. We access funding in a variety of markets in the Americas, Europe and Asia. We have imposed various internal guidelines on creditor concentration, including the amount of our commercial paper that can be owned and letters of credit that can be issued by any single creditor or group of creditors.
See “Risk Factors” in Part I, Item 1A of the Annual Report on Form 10-K for a discussion of factors that could impair our ability to access the capital markets.
Subsidiary Funding Policies. Substantially all of our unsecured funding is raised by our parent company, Group Inc. The parent company then lends the necessary funds to its subsidiaries, some of which are regulated, to meet their asset financing and capital requirements. In addition, the parent company provides its regulated subsidiaries with the necessary capital to meet their regulatory requirements. The benefits of this approach to subsidiary funding include enhanced control and greater flexibility to meet the funding requirements of our subsidiaries.
Our intercompany funding policies are predicated on an assumption that, unless legally provided for, funds or securities are not freely available from a subsidiary to its parent company or other subsidiaries. In particular, many of our subsidiaries are subject to laws that authorize regulatory bodies to block or limit the flow of funds from those subsidiaries to Group Inc. Regulatory action of that kind could impede access to funds that Group Inc. needs to make payments on obligations, including debt obligations. As such, we assume that capital or other financing provided to our regulated subsidiaries is not available to our parent company or other subsidiaries. In addition, we assume that the Global Core Excess held in our principal non-U.S. operating entities will not be available to our parent company or other subsidiaries and therefore is available only to meet the potential liquidity requirements of those entities.
We also manage our liquidity risk by requiring senior and subordinated intercompany loans to have maturities equal to or shorter than the maturities of the aggregate borrowings of the parent company. This policy ensures that the subsidiaries’ obligations to the parent company will generally mature in advance of the parent company’s third-party borrowings. In addition, many of our subsidiaries and affiliates maintain unencumbered assets to cover their intercompany borrowings (other than subordinated debt) in order to mitigate parent company liquidity risk.
Group Inc. has provided substantial amounts of equity and subordinated indebtedness, directly or indirectly, to its regulated subsidiaries; for example, as of May 2008, Group Inc. had $25.05 billion of such equity and subordinated indebtedness invested in Goldman, Sachs & Co., its principal U.S. registered broker-dealer; $25.74 billion invested in Goldman Sachs International, a regulated U.K. broker-dealer; $2.25 billion invested in Goldman Sachs Execution & Clearing, L.P., a U.S. registered broker-dealer; and $3.66 billion invested in Goldman Sachs Japan Co., Ltd., a regulated Japanese broker-dealer. Group Inc. also had $58.10 billion of unsubordinated loans to these entities as of May 2008, as well as significant amounts of capital invested in and loans to its other regulated subsidiaries.
