Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table summarizes financial assets and financial liabilities that we measured at fair value on a recurring basis at the dates indicated, classified in accordance with the fair value hierarchy described above.
## Table 0 ##
(1) Carrying value on our balance sheet at July 31, 2016 was $500 million.
See Note 7, “Current Liabilities – Short-Term Debt” for more information.
The following table summarizes our cash equivalents and available-for-sale debt securities by balance sheet classification and level in the fair value hierarchy at the dates shown:
## Table 1 ##
We value our Level 1 assets, consisting primarily of money market funds and time deposits, using quoted prices in active markets for identical instruments.
Financial assets whose fair values we measure on a recurring basis using Level 2 inputs consist of municipal bonds, corporate notes and U. S.  agency securities.
We measure the fair values of these assets with the help of a pricing service that either provides quoted market prices in active markets for identical or similar securities or uses observable inputs for their pricing without applying significant adjustments.
Our fair value processes include controls that are designed to ensure that we record appropriate fair values for our Level 2 investments.
These controls include comparison to pricing provided by a secondary pricing service or investment manager, validation of pricing sources and models, review of key model inputs, analysis of period-over-period price fluctuations, and independent recalculation of prices where appropriate.
Financial liabilities whose fair values we measured using Level 2 inputs consisted of senior unsecured notes.
We repaid those notes during the third quarter of fiscal 2017.
See Note 7, “Current Liabilities – Short-Term Debt,” for more information.
We measured the fair value of our senior notes based on their trading prices and the interest rates we could obtain for other borrowings with similar terms.

Current Liabilities Short-Term Debt Short-term debt at July 31, 2016 included $500 million of 5.75% senior unsecured notes due on March 15, 2017, less the unamortized discount.
During the third quarter of fiscal 2017 we repaid those notes when they became due using cash from operations.
We paid $29 million in cash for interest on the notes during each of the twelve months ended July 31, 2017, July 31, 2016, and July 31, 2015.
On February 1, 2016 we entered into a master credit agreement with certain institutional lenders for a five-year credit facility in an aggregate principal amount of $1.5 billion.
The master credit agreement includes a $500 million unsecured term loan and a $1 billion unsecured revolving credit facility.
At July 31, 2017, $488 million was outstanding under the term loan, of which $50 million was classified as short-term debt.
See Note 8, “Long-Term Obligations and Commitments – Long-Term Debt,” for more information regarding the term loan.
Unsecured Revolving Credit Facilities The master credit agreement we entered into on February 1, 2016 includes a $1 billion unsecured revolving credit facility that will expire on February 1, 2021.
Under the master credit agreement we may, subject to certain customary conditions, on one or more occasions increase commitments under the revolving credit facility in an amount not to exceed $250 million in the aggregate and may extend the maturity date up to two times.
Advances under the revolving credit facility accrue interest at rates that are equal to, at our election, either Bank of America's alternate base rate plus a margin that ranges from 0.0% to 0.5% or the London Interbank Offered Rate (LIBOR) plus a margin that ranges from 0.9% to 1.5%.
Actual margins under either election will be based on our senior debt credit ratings.
The master credit agreement includes customary affirmative and negative covenants, including financial covenants that require us to maintain a ratio of total debt to annual earnings before interest, taxes, depreciation and amortization (EBITDA) of not greater than 3.25 to 1.00 as of any date and a ratio of annual EBITDA to annual interest expense of not less than 3.00 to 1.00 as of the last day of each fiscal quarter.
We remained in compliance with these covenants at all times during the fiscal year ended July 31, 2017.
During the twelve months ended July 31, 2017 we borrowed and repaid $150 million under this revolving credit facility and at July 31, 2017 no amounts were outstanding.
We paid $1 million in cash for interest on the revolving credit facility during the twelve months ended July 31, 2017 and $2 million in cash for interest on revolving credit facilities during the twelve months ended July 31, 2016.
Other Current Liabilities Other current liabilities were as follows at the dates indicated:

Long-Term Obligations and Commitments Long-Term Debt On February 1, 2016 we entered into a master credit agreement with certain institutional lenders for a five-year credit facility in an aggregate principal amount of $1.5 billion, which includes a $500 million unsecured term loan.
Under the master credit agreement we may, subject to certain customary conditions, on one or more occasions increase commitments under the term loan in an amount not to exceed $500 million in the aggregate.
The term loan accrues interest at rates that are equal to, at our
credit facilities.
As such, our foreign cash and cash equivalents are not expected to be a key source of liquidity to our domestic operations.
At September 30, 2019, we had approximately $2.9 billion of availability under our committed credit facilities, primarily under our revolving credit facility, the majority of which matures on July 1, 2022.
This liquidity may be used to provide for ongoing working capital needs and for other general corporate purposes, including acquisitions, dividends and stock repurchases.
Certain restrictive covenants govern our maximum availability under the credit facilities.
We test and report our compliance with these covenants as required and we were in compliance with all of these covenants at September 30, 2019.
At September 30, 2019, we had $129.8 million of outstanding letters of credit not drawn upon.
Cash and cash equivalents were $151.6 million at September 30, 2019 and $636.8 million at September 30, 2018.
We used a significant portion of the cash and cash equivalents on hand at September 30, 2018 in connection with the closing of the KapStone Acquisition.
Primarily all of the cash and cash equivalents at September 30, 2019 were held outside of the U. S.  At September 30, 2019, total debt was $10,063.4 million, $561.1 million of which was current.
At September 30, 2018, total debt was $6,415.2 million, $740.7 million of which was current.
The increase in debt was primarily related to the KapStone Acquisition.
## Table 3 ##
Net cash provided by operating activities during fiscal 2019 increased $379.0 million from fiscal 2018 primarily due to higher cash earnings and a $340.3 million net decrease in the use of working capital compared to the prior year.
As a result of the retrospective adoption of ASU 2016-15 and ASU 2016-18 (each as hereinafter defined) as discussed in “Note 1.
Description of Business and Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements, net cash provided by operating activities for fiscal 2018 was reduced by $489.7 million and cash provided by investing activities increased $483.8 million, primarily for the change in classification of proceeds received for beneficial interests obtained for transferring trade receivables in securitization transactions.
Net cash used for investing activities of $4,579.6 million in fiscal 2019 consisted primarily of $3,374.2 million for cash paid for the purchase of businesses, net of cash acquired (excluding the assumption of debt), primarily related to the KapStone Acquisition, and $1,369.1 million for capital expenditures that were partially offset by $119.1 million of proceeds from the sale of property, plant and equipment primarily related to the sale of our Atlanta beverage facility, $33.2 million of proceeds from corporate owned life insurance benefits and $25.5 million of proceeds from property, plant and equipment insurance proceeds related to the Panama City, FL mill.
Net cash used for investing activities of $815.1 million in fiscal 2018 consisted primarily of $999.9 million for capital expenditures, $239.9 million for cash paid for the purchase of businesses, net of cash acquired primarily related to the Plymouth Acquisition and the Schlüter Acquisition, and $108.0 million for an investment in Grupo Gondi.
These investments were partially offset by $461.6 million of cash receipts on sold trade receivables as a result of the adoption of ASU 2016-15, $24.0 million of proceeds from the sale of certain affiliates as well as our solid waste management brokerage services business and $23.3 million of proceeds from the sale of property, plant and equipment.
In fiscal 2019, net cash provided by financing activities of $1,780.2 million consisted primarily of a net increase in debt of $2,314.6 million, primarily related to the KapStone Acquisition and partially offset by cash dividends paid to stockholders of $467.9 million and purchases of Common Stock of $88.6 million.
In fiscal 2018, net cash used for financing activities of $755.1 million consisted primarily of cash dividends paid to stockholders of $440.9 million and purchases of Common Stock of $195.1 million and net repayments of debt of $120.1 million.
