Liability related to sale of future royalties:

On January 7, 2018, the Company entered into a funding agreement (the "Funding Agreement") with RPI Finance Trust, a Delaware statutory trust ("RPI"). Pursuant to the Funding Agreement, the Company issued to RPI the right to receive certain royalty amounts, subject to certain reductions, based on the net sales of the ADC sacituzumab govitecan (the "Product"), for each calendar quarter during the term of the Funding Agreement ("Revenue Participation Right"), in exchange for $175.0 million in cash (the "Purchase Price"). Specifically, the royalty rate commences at 4.15 percent on net annual sales of up to $2.0 billion, declining step-wise based on sales tiers to 1.75 percent on net global annual sales exceeding $6.0 billion.

On January 7, 2018, in connection with the Funding Agreement, the Company entered into a common stock purchase agreement (the "Purchase Agreement") with RPI, pursuant to which the Company, in a private placement, issued and sold to RPI 4,373,178 unregistered shares (the "Shares") of the Company's Common Stock, at a price of $17.15 per share for gross proceeds to the Company of $75.0 million before deducting fees and expenses (the "Financing").

The Company concluded that there were two units of accounting in the transaction. The Company allocated the transaction consideration on a relative fair value to the liability and common stock in accordance with ASC 470-10 as follows (in thousands):

Convertible Senior Notes:

In February 2015, the Company issued $100.0 million of Convertible Senior Notes (the "Convertible Senior Notes") (net proceeds of approximately $96.3 million after deducting the initial purchasers’ fees and offering expenses) in a private offering exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon Rule 144A under the Securities Act (the "Convertible Senior Notes"). The Convertible Senior Notes will mature on February 15, 2020, unless earlier purchased or converted. The debt issuance costs of approximately $3.7 million, primarily consisting of underwriting, legal and other professional fees, are amortized over the term of the Convertible Senior Notes. The Convertible Senior Notes are senior unsecured obligations of the Company. Interest at 4.75% is payable semiannually on February 15 and August 15 of each year. The effective interest rate on the Convertible Senior Notes was 5.48% for the period from the date of issuance through June 30, 2018.

The Convertible Senior Notes are convertible at the option of holders into approximately 19.6 million shares of common stock at any time prior to the close of business on the day immediately preceding the maturity date. The exchange rate will initially be 195.8336 shares of common stock per $1,000 principal amount of Convertible Senior Notes (equivalent to an initial conversion price of approximately $5.11 per share of common stock).

If the Company undergoes a fundamental change (as defined in the indenture governing the Convertible Senior Notes), holders may require Immunomedics to purchase for cash all or part of the Convertible Senior Notes at a purchase price equal to 100% of the principal amount of the Convertible Senior Notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date, subject to certain exceptions. In addition, if certain make-whole fundamental changes (as defined in the indenture governing the Convertible Senior Notes) occur, Immunomedics will, in certain circumstances, increase the conversion rate for any Convertible Note converted in connection with such make-whole fundamental change.

The indenture does not limit the amount of debt which may be issued by the Company under the indenture or otherwise, does not contain any financial covenants or restrict the Company from paying dividends, selling or disposing of assets, or issuing or repurchasing its other securities, provided that such event is not deemed to be a fundamental change (as defined in the indenture governing the Convertible Senior Notes). The indenture contains customary terms and covenants and events of default.

If an event of default with respect to the Convertible Senior Notes occurs, holders may, upon satisfaction of certain conditions, accelerate the principal amount of the Convertible Senior Notes plus premium, if any, and accrued and unpaid interest, if any. In addition, the principal amount of the Convertible Senior Notes plus premium, if any, and accrued and unpaid interest, if any, will automatically become due and payable in the case of certain types of bankruptcy or insolvency events of default involving the Company.

On September 21, 2017, the Company entered into separate, privately negotiated exchange agreements, (the "Exchange Agreements") with certain holders of the Convertible Senior Notes. Under the Exchange Agreements, such holders agreed to convert an aggregate $80.0 million of Convertible Senior Notes held by them. The Company initially settled each $1,000 principal amount of Convertible Senior Notes surrendered for exchange by delivering 176.2502 shares of common stock in three tranches occurring on September 19, 2017 through September 21, 2017. In total, the Company issued an aggregate 16,799,861 in the Exchange Agreements. The shares represent an aggregate of 1,133,173 shares more than the number of shares into which the exchanged Convertible Senior Notes were convertible under their original terms. As a result of the Exchange Agreements, the Company recognized a loss on induced exchanges of debt of $13.0 million representing the fair value of the incremental consideration paid to induce the holders to exchange their Convertible Senior Notes for equity (i.e., 1,133,173 Common Shares), based on the closing market price of the Company's Common Stock on the date of the Exchange Agreements.

As a result of the Exchange Agreements, the outstanding aggregate principal amount of the Convertible Senior notes was reduced to $20.0 million.

Total interest expense for the Convertible Senior Notes for the fiscal years ended June 30, 2018, 2017, and 2016 were $3.5 million, $5.5 million and $5.5 million, respectively. Included in interest expense is the amortization of debt issuance costs of $1.7 million ($1.4 million of which related to the accelerated amortization of debt issuance costs associated with the $80.0 million exchange of Convertible Senior Notes in September 2017), $0.7 million and $0.7 million for the fiscal years ended June 30, 2018, 2017, and 2016, respectively.
