conditions, including any developments related to the COVID-19 pandemic. We believe that we have sufficient financial resources and liquidity which will enable us to meet our ongoing working capital and other cash flow needs.
Cash Flows from Operating Activities
In the first nine months of fiscal 2021, net cash provided by operating activities increased $630 million to $1,902 million from $1,272 million in the first nine months of fiscal 2020. The increase resulted primarily from higher pre-tax income and increased accounts payable levels driven by higher production volumes, partially offset by the impact of increased sales on accounts receivable levels. The amount of income taxes paid, net of refunds, during the first nine months of fiscal 2021 and 2020 was $291 million and $195 million, respectively.
Cash Flows from Investing Activities
Capital expenditures were $454 million and $439 million in the first nine months of fiscal 2021 and 2020, respectively. We expect fiscal 2021 capital spending levels to be approximately 4-5% of net sales. We believe our capital funding levels are adequate to support new programs, and we continue to invest in our manufacturing infrastructure to further enhance productivity and manufacturing capabilities.
During the first nine months of fiscal 2021, we acquired two businesses for a combined cash purchase price of $125 million, net of cash acquired. We acquired four businesses, including First Sensor AG, for a combined cash purchase price of $325 million, net of cash acquired, during the first nine months of fiscal 2020. See Note 3 to the Condensed Consolidated Financial Statements for additional information regarding acquisitions.
Cash Flows from Financing Activities and Capitalization
Total debt at June 25, 2021 and September 25, 2020 was $4,134 million and $4,146 million, respectively. See Note 7 to the Condensed Consolidated Financial Statements for additional information regarding debt.
During the first nine months of fiscal 2021, Tyco Electronics Group S.A. (“TEGSA”), our wholly-owned subsidiary, repaid, at maturity, $250 million of 4.875% senior notes due in January 2021 and €350 million of fixed-to-floating rate senior notes due in June 2021.
During the first nine months of fiscal 2021, TEGSA issued €550 million aggregate principal amount of 0.00% senior notes due in February 2029. The notes are TEGSA’s unsecured senior obligations and rank equally in right of payment with all existing and any future senior indebtedness of TEGSA and senior to any subordinated indebtedness that TEGSA may incur.
TEGSA has a five-year unsecured senior revolving credit facility (“Credit Facility”) with total commitments of $1.5 billion. The Credit Facility was amended in June 2021 primarily to extend the maturity date from November 2023 to June 2026. The amended Credit Facility contains customary provisions for the replacement of London Interbank Offered Rate (“LIBOR”) with successor rates and amends certain representations, warranties, and covenants applicable to us and TEGSA as obligors under the credit agreement. TEGSA had no borrowings under the Credit Facility at June 25, 2021 or September 25, 2020.
Borrowings under the Credit Facility bear interest at a rate per annum equal to, at the option of TEGSA, (1) LIBOR or, upon a phase-out of LIBOR, an alternative benchmark rate, (2) an alternate base rate equal to the highest of (i) Bank of America, N.A.’s base rate, (ii) the federal funds effective rate plus 1/2 of 1%, and (iii) one-month LIBOR, or an alternative benchmark rate, plus 1%, (3) an alternative currency daily rate, or (4) an alternative currency term rate, plus, in each case, an applicable margin based upon the senior, unsecured, long-term debt rating of TEGSA. TEGSA is required to pay an annual facility fee. Based on the applicable credit ratings of TEGSA, this fee ranges from 5.0 to 12.5 basis points of the lenders’ commitments under the Credit Facility.
The Credit Facility contains a financial ratio covenant providing that if, as of the last day of each fiscal quarter, our ratio of Consolidated Total Debt to Consolidated EBITDA (as defined in the Credit Facility) for the then most recently concluded period of four consecutive fiscal quarters exceeds 3.75 to 1.0, an Event of Default (as defined in the Credit
