On June 15, 2017, the Company completed a public offering of $500 million aggregate principal amount of the Company's 3.45% senior unsecured and unsubordinated notes due in June 2027 (“2027 Notes”), with an effective interest rate of 3.5%. Interest on the 2027 Notes is payable semi-annually in arrears on June 15 and December 15 of each year, commencing on December 15, 2017. The net proceeds of this offering were approximately $495.2 million, after issuing at a discount and deducting paid expenses.

On March 18, 2013, the Company completed a public offering of $500 million aggregate principal amount of the Company's 3.375% senior unsecured and unsubordinated notes due in March 2023 (“2023 Notes”), with an effective interest rate of 3.5%. Interest on the 2023 Notes is payable semi-annually in arrears on March 15 and September 15 of each year. The net proceeds of this offering were approximately $490.0 million, after issuing at a discount and deducting paid expenses.

The debt indentures that govern the 2027 and the 2023 Notes include covenants that limit the Company's ability to grant liens on its facilities and to enter into sale and leaseback transactions, which could limit the Company's ability to secure additional debt funding in the future. In circumstances involving a change of control of the Company followed by a downgrade of the rating of the 2027 Notes or the 2023 Notes, the Company would be required to make an offer to repurchase the affected notes at a purchase price equal to 101% of the aggregate principal amount of such notes, plus accrued and unpaid interest.

The Company accounts for all the notes above based on their amortized cost. The discount and expenses are being amortized to Interest and other income (expense), net in the Consolidated Statements of Income over the life of the notes. The interest expense is recorded in Interest and other income (expense), net in the Consolidated Statements of Income. Amortized discount and expenses, as well as interest expense associated with the notes was $35.6 million, $35.6 million and $41.4 million during the years ended June 26, 2021, June 27, 2020, and June 29, 2019, respectively.

The estimated fair value of the Company's outstanding debt obligations was approximately $1.1 billion as of June 26, 2021. The estimated fair value of the debt is based primarily on observable market inputs and is a Level 2 measurement.

The Company recorded interest expense of $37.8 million, $38.0 million, and $43.5 million during the fiscal years ended June 26, 2021, June 27, 2020, and June 29, 2019, respectively.

For the balance of the Company's financial instruments, cash equivalents, accounts receivable, accounts payable and other accrued liabilities, the carrying amounts approximate fair value due to their short maturities.
