charge in connection with the redemption of an intercompany minority interest. These net benefits were recorded within income tax (benefit) provision in the consolidated statement of income for the six months ended October 28, 2016.
LIQUIDITY AND CAPITAL RESOURCES
We believe our balance sheet and liquidity provide us with flexibility in the future. Approximately $5 billion of our cash, cash equivalents, and investments held by certain U.S.-controlled non-U.S. subsidiaries may not represent available liquidity for general corporate purposes. However, we believe our other existing cash, cash equivalents and investments, as well as our $3.5 billion revolving credit facility and related commercial paper program ($700 million of commercial paper outstanding at October 27, 2017), will satisfy our foreseeable operating needs for at least the next 12 months. We regularly review our capital needs and consider various investing and financing alternatives to support our requirements.
Standard & Poor's Ratings Services (S&P) and Moody's Investors Service (Moody's) long-term debt ratings and short-term debt ratings at October 27, 2017 were unchanged as compared to the ratings at April 28, 2017. We do not expect the S&P and Moody's ratings to have a significant impact on our liquidity or future flexibility to access additional liquidity given our balance sheet and our $3.5 billion revolving credit facility and related commercial paper program.
We have future contractual obligations and other minimum commercial commitments that are entered into in the normal course of business. We believe our off-balance sheet arrangements do not have a material current or anticipated future effect on our consolidated earnings, financial position, and/or cash flows.
Note 17 to the consolidated financial statements provides information regarding amounts we have accrued related to legal proceedings. In accordance with U.S. GAAP, we record a liability in our consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. Actual settlements may be different than estimated and could have a material impact on our consolidated earnings, financial position, and/or cash flows.
We record tax liabilities in our consolidated financial statements for amounts that we expect to repatriate from subsidiaries (to the extent the repatriation would be subject to tax); however, no tax liabilities are recorded for amounts that we consider to be permanently reinvested. Our current plans do not foresee a need to repatriate funds that are designated as permanently reinvested in order to fund our operations or meet currently anticipated liquidity and capital investment needs. However, we evaluate our legal entity structure supporting our business operations, and to the extent such evaluation results in a change to our overall business structure, we may be required to accrue for additional tax obligations.
We have investments in marketable debt securities that are classified and accounted for as available-for-sale. Our debt securities include U.S. government and agency securities, corporate debt securities, mortgage-backed securities, other asset-backed securities, debt funds, and auction rate securities. Some of our investments may experience reduced liquidity due to changes in market
