(1) As each of the convertible debt instruments may be settled in cash upon conversion, for accounting purposes, they were bifurcated into a liability component and an equity component. The amount allocated to the equity component is the difference between the principal value of the instrument and the fair value of the liability component at issuance. The resulting debt discount is being amortized to interest expense at the respective effective interest rate over the contractual term of the debt. (2) The 0.983% 2024 Notes mature on September 1, 2024, and interest is payable semi-annually in arrears on March 1 and September 1 of each year.

Ranking of Convertible Debt - The Convertible Debt are unsecured obligations which are subordinated in right of payment to the amounts outstanding under the Company's Senior Indebtedness. The 2017 Junior Convertible Debt is expressly subordinated in right of payment to any existing and future senior debt of the Company (including the Senior Indebtedness and the Senior Subordinated Convertible Debt) and is structurally subordinated in right of payment to the liabilities of the Company's subsidiaries. The Senior Subordinated Convertible Debt is subordinated to the Senior Indebtedness; ranks senior to the Company's indebtedness that is expressly subordinated in right of payment to it, including the 2017 Junior Convertible Debt; ranks equal in right of payment to any of the Company's unsubordinated indebtedness that does not provide that it is senior to the Senior Subordinated Convertible Debt; ranks junior in right of payment to any of the Company's secured and unsecured unsubordinated indebtedness to the extent of the value of the assets securing such indebtedness; and is structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries. Summary of Conversion Features - Each series of Convertible Debt is convertible, subject to certain conditions, into cash, shares of the Company's common stock or a combination thereof, at the Company's election, at specified conversion rates (see table below), adjusted for certain events including the declaration of cash dividends. Except during the three-month period immediately preceding the maturity date of the applicable series of Convertible Debt, each series of Convertible Debt is convertible only upon the occurrence of (i) such time as the closing price of the Company's common stock exceeds the applicable conversion price (see table below) by 130% for 20 days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter or (ii) during the 5 business day period after any 10 consecutive trading day period, or the measurement period, in which the trading price per $1,000 principal amount of notes of a given series for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the applicable conversion rate on each such trading day or (iii) upon the occurrence of certain corporate events specified in the indenture of such series of Convertible Debt. In addition, for each series, with the exception of the 2020 Senior Convertible Debt, if at the time of conversion the applicable price of the Company's common stock exceeds the applicable conversion price at such time, the applicable conversion rate will be increased by up to an additional maximum incremental shares rate, as determined pursuant to a formula specified in the indenture for the applicable series of Convertible Debt, and as adjusted for cash dividends paid since the issuance of such series of Convertible Debt. However, in no event will the applicable conversion rate exceed the applicable maximum conversion rate specified in the indenture for the applicable series of Convertible Debt (see table below). The following table sets forth the applicable conversion rates adjusted for dividends declared since issuance of such series of Convertible Debt and the applicable incremental share factors and maximum conversion rates as adjusted for dividends paid since the applicable issuance date:
| Dividend adjusted rates as of September 30, 2021
| Conversion Rate |  | Approximate Conversion Price |  | Incremental Share Factor |  | Maximum Conversion Rate
2015 Senior Convertible Debt(1) | 33.2337 |  |  | $ | 30.09 |  |  | 16.6168 |  |  | 46.5270 |

(1) As of September 30, 2021, the 2020 Senior Convertible Debt was not convertible. As of September 30, 2021, the holders of each of the 2015 Senior Convertible Debt, 2017 Senior Convertible Debt, and 2017 Junior Convertible Debt have the right to convert their notes between October 1, 2021 and December 31, 2021 because the Company's common stock price has exceeded the applicable conversion price for such series by 130% for the specified period of time during the quarter ended September 30, 2021. As of September 30, 2021, the adjusted conversion rate for the 2015 Senior Convertible Debt, 2017 Senior Convertible Debt, and 2017 Junior Convertible Debt would be increased to 43.3354 shares of common stock, 25.4520 shares of common stock, and 26.0230 shares of common stock, respectively, per $1,000 principal amount of notes based on the closing price of $76.75 per share of common stock to include an additional maximum incremental share rate per the terms of the applicable indenture. As of September 30, 2021, each of the 2015 Senior Convertible Debt, 2017 Senior Convertible Debt, and 2017 Junior Convertible Debt had a conversion value in excess of par of $165.2 million, $221.8 million, and $30.0 million, respectively. With the exception of the 2020 Senior Convertible Debt, which may be redeemed by the Company on or after November 20, 2022, the Company may not redeem any series of Convertible Debt prior to the relevant maturity date and no sinking fund is provided for any series of Convertible Debt. Under the terms of the applicable indenture, the Company may repurchase any series of Convertible Debt in the open market through privately negotiated exchange offers. Upon the occurrence of a fundamental change, as defined in the applicable indenture of such series of Convertible Debt, holders of such series may require the Company to purchase all or a portion of their Convertible Debt for cash at a price equal to 100% of the principal amount plus any accrued and unpaid interest.

(1) The Company settled portions of its convertible debt in privately negotiated transactions that are accounted for as induced conversions. (2) The total consideration for the convertible debt settlements was allocated to the liability and equity components using the equivalent rate that reflected the borrowing rate for a similar non-convertible debt instrument prior to the settlement. (3) The Company used borrowings under its Revolving Credit Facility to finance a portion of such settlement. (4) The Company used proceeds from the issuance of the 0.983% 2024 Notes to finance a portion of such settlement. 0.983% 2024 Notes The Company may, at its option, redeem some or all of the 0.983% 2024 Notes in the manner set forth in the 0.983% 2024 Notes indenture. If the Company experiences a specified change of control triggering event set forth in the 0.983% 2024 Notes indenture the Company must offer to repurchase the 0.983% 2024 Notes at a price equal to 101% of the principal amount of the note repurchased, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. The 0.983% 2024 Notes indenture contains certain customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries' ability to, among other things, create or incur certain liens, and enter into sale and leaseback transactions, sell or otherwise dispose of any assets constituting collateral securing the 0.983% 2024 Notes, and consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its assets, to another person. These covenants are subject to a number of limitations and exceptions set forth in the 0.983% 2024 Notes indenture. The 0.983% 2024 Notes are guaranteed by certain of the Company's subsidiaries that have also guaranteed the obligations under the Credit Agreement and under the Company’s existing Senior Indebtedness. In the future, each subsidiary of the Company that is a guarantor or other obligor of the Credit Agreement is required to guarantee the 0.983% 2024 Notes. The 0.983% 2024 Notes and the 0.983% 2024 Notes guarantees are secured, on a pari passu first lien basis with the Credit Agreement, by substantially all of the tangible and intangible assets (other than certain excluded assets) of the Company and the guarantors that secure obligations under the Credit Agreement, in each case subject to certain thresholds, exceptions and permitted liens, as set forth in the respective security agreement, by and among the Company, the subsidiary guarantors party thereto and the collateral agent.
