Other (Income) Expense, Net. Other (income) expense, net increased $5.4 million in the first six months of fiscal 2019 compared to the same period in the prior year. The increase was primarily due to a $5.0 million charge related to the write-off of an investment in a liquidated business.
Income Taxes. The effective tax rate was 24.6% for the first six months of fiscal 2019 compared to 33.9% for the first six months of fiscal 2018. The effective tax rate for the first six months of fiscal 2019 was lower than the same period in the prior year due primarily to an $8.1 million charge in the first quarter of 2018 related to repatriation taxes for accumulated earnings of our foreign subsidiaries associated with the enactment of the Tax Cuts and Jobs Act of 2017 and a tax benefit in fiscal 2019 associated with a state income tax settlement. The decrease was partially offset by the vesting of restricted shares and the expiration of certain vested stock options.
Liquidity and Capital Resources
We require cash principally for day-to-day operations, to finance capital investments (including possible acquisitions), purchase inventory, service our outstanding debt and for seasonal working capital needs. We expect that our available cash, cash flow generated from operating activities and funds available under our senior secured asset-based revolving credit facility (“Amended Revolving Credit Facility”) will be sufficient to fund planned capital expenditures, working capital requirements, debt repayments, debt service requirements and anticipated growth for the foreseeable future. Our ability to satisfy our liquidity needs and continue to refinance or reduce debt could be adversely affected by the occurrence of any of the events described under “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended February 2, 2019 or our failure to meet our debt covenants. Our Amended Revolving Credit Facility provides senior secured financing of up to $850 million, subject to a borrowing base. As of August 3, 2019, the borrowing base was $789.3 million, of which we had $103.2 million of outstanding standby letters of credit and $686.1 million of unused borrowing capacity. On August 30, 2019, the Amended Revolving Credit Facility was amended to extend the maturity to August 2024. There were no other significant changes to the terms under the Amended Revolving Credit Facility. Our cash and cash equivalents totaled $131.0 million at August 3, 2019.
We had total outstanding debt of $2,695 million at August 3, 2019, of which $2,195 million was subject to variable interest rates and $500 million was subject to fixed interest rates. In April 2018, we executed two interest rate swaps with an aggregate notional value of $1 billion associated with our outstanding Amended and Restated Term Loan Credit Facility. The swaps replaced the one-month LIBOR with a fixed interest rate of 2.7765%.
On July 8, 2019, Michaels Stores, Inc. (“MSI”) issued $500 million in principal amount of 8% senior notes maturing in 2027 (“2027 Senior Notes”). The 2027 Senior Notes were issued pursuant to an indenture among MSI, certain subsidiaries of MSI, as guarantors, and U.S. Bank National Association, as trustee (the “2027 Senior Notes Indenture”). The 2027 Senior Notes mature on July 15, 2027 and bear interest at a rate of 8% per year, with interest payable semi-annually on January 15 and July 15 of each year, beginning on January 15, 2020.
The net proceeds from the offering and sale of the 2027 Senior Notes, together with cash on hand, were used to redeem MSI’s outstanding senior subordinated notes.
The 2027 Senior Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of MSI’s subsidiaries that guarantee indebtedness under the Amended Revolving Credit Facility and the senior secured term loan facility (“Amended and Restated Term Loan Credit Facility”) (collectively defined as the “Senior Secured Credit Facilities”).
The 2027 Senior Notes are general, unsecured obligations of MSI, and the guarantees of the 2027 Senior Notes are general, unsecured obligations of the guarantors. They (i) rank equally in right of payment with all of MSI’s and the guarantors’ existing and future senior debt, including the Senior Secured Credit Facilities, (ii) are effectively subordinated to any of MSI’s and the guarantors’ existing and future secured debt to the extent of the value of the assets securing such debt, including the Senior Secured Credit Facilities, (iii) are structurally subordinated to all of the liabilities of MSI’s subsidiaries that are not guaranteeing the 2027 Senior Notes, and (iv) are senior in right of payment with all of MSI’s and the guarantors’ existing and future subordinated debt.
