Credit Agreement.

During the nine months ended September 30, 2016, we made $5.6 million of principal repayments on our 2015 Term Loan. As of September 30, 2016, our interest rate on the 2015 Term Loan is 2.59% (adjusted LIBOR plus 1.75% per annum), effective through December 30, 2016, and our commitment fee on the unused 2015 Revolver is 0.25%. As of September 30, 2016, we had no borrowing outstanding on our 2015 Revolver and had the entire $200.0 million available to us.

Convertible Notes.

2016 Convertible Notes. In March 2016, we completed an offering of $230 million of 4.25% senior convertible notes due March 15, 2036 (the “2016 Convertible Notes”) to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The 2016 Convertible Notes are unsecured obligations and will pay 4.25% annual cash interest, payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2016.

The 2016 Convertible Notes will be convertible at the option of the note holders upon the satisfaction of specified conditions and during certain periods. During the period from, and including, December 15, 2021 to the close of business on the business day immediately preceding March 15, 2022 and on or after December 15, 2035, holders may convert all or any portion of their 2016 Convertible Notes at the conversion rate then in effect at any time regardless of these conditions. The 2016 Convertible Notes will be convertible at an initial conversion rate of 17.4642 shares of our common stock per $1,000 principal amount of the 2016 Convertible Notes, which is equivalent to an initial conversion price of approximately $57.26 per share of our common stock. We will settle conversions of the 2016 Convertible Notes by paying or delivering, as the case may be, cash, shares of our common stock, or a combination thereof, at our election. It is our current intent and policy to settle our conversion obligations as follows: (i) pay cash for 100% of the par value of the 2016 Convertible Notes that are converted; and (ii) to the extent the value of our conversion obligation exceeds the par value, we can satisfy the remaining conversion obligation in our common stock, cash or a combination thereof.

Holders may require CSG to repurchase the 2016 Convertible Notes for cash on each of March 15, 2022, March 15, 2026, and March 15, 2031, or upon the occurrence of a fundamental change (as defined in the 2016 Convertible Notes Indenture (“2016 Notes Indenture”)) in each case at a purchase price equal to the principal amount thereof plus accrued and unpaid interest.

We may not redeem the 2016 Convertible Notes prior to March 20, 2020. On or after March 20, 2020, we may redeem for cash all or part of the 2016 Convertible Notes if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which CSG provides notice of redemption. On or after March 15, 2022, we may redeem for cash all or part of the 2016 Convertible Notes regardless of the sales price condition described in the preceding sentence. In each case, the redemption price will equal the principal amount of the 2016 Convertible Notes to be redeemed, plus accrued and unpaid interest.

The 2016 Notes Indenture includes customary terms and covenants, including certain events of default after which the 2016 Convertible Notes may be due and payable immediately. The Notes Indenture contains customary affirmative covenants, including compliance with terms of certain other indebtedness of the Company over a defined threshold amount.

The net proceeds from the sale of the 2016 Convertible Notes were approximately $223 million after deducting the initial purchasers’ discount and estimated offering expenses payable by us. As of September 30, 2016, we repurchased approximately $115 million aggregate principal amount of our 2010 Convertible Notes for $215.6 million (see additional discussion in 2010 Convertible Notes below) with the net proceeds from the offering of the 2016 Convertible Notes. The remainder of the net proceeds will be used to settle the outstanding 2010 Convertible Notes.

The original issue discount (“OID”) related to the 2016 Convertible Notes of $15.9 million, as a result of an effective interest rate of the liability component of 5.63% compared to the cash interest rate of 4.25%, is being amortized to interest expense through December 15, 2021, the first date the 2016 Convertible Notes can be put back to us by the holders.

2010 Convertible Notes.

As of September 30, 2016, we made the following repurchases of our 2010 Convertible Notes (in millions):

Date	Aggregate Principal Amount Repurchased		Total Purchase Price		Loss on Repurchases (1)
March 15, 2016	$	40.0	$	72.6	$	3.2
April 8, 2016		66.2		125.8		5.1
September 2, 2016		9.1		17.2		0.3
Totals	$	115.3	$	215.6	$	8.6

(1)	Loss on the repurchases includes the write-off of unamortized deferred financing costs and OID.

In addition, during the third quarter of 2016, we had holders convert $40,000 aggregate principal amount of the 2010 Convertible Notes for a total price of $0.1 million. As of September 30, 2016, the principal outstanding on the 2010 Convertible Notes was $34.7 million.

As the result of our declaring a cash dividend in August 2016 (see Note 8), the previous conversion rate for the 2010 Convertible Notes of 43.9954 shares of our common stock for each $1,000 in principal amount of the 2010 Convertible Notes (equivalent to a conversion price of $22.73 per share of our common stock) has been adjusted to 44.1816 shares of our common stock for each $1,000 in principal amount of the 2010 Convertible Notes (equivalent to a conversion price of $22.63 per share of our common stock).

Prior to September 1, 2016, holders of the 2010 Convertible Notes could convert their securities at any time in the fiscal quarter following the period in which the price of our common stock trades over 130% of the conversion price for at least 20 consecutive trading days in the last 30 trading days of a fiscal quarter. On or after September 1, 2016, the holders of the 2010 Convertible Notes can elect to convert their securities at any time, with settlement occurring on March 1, 2017. As of March 16, 2016, the closing price of our common stock exceeded 130% of the conversion price for the required period, thus allowing the 2010 Convertible Notes to be converted at the holder’s option during the quarter beginning April 1, 2016 and ending June 30, 2016. In addition, as of June 16, 2016, the closing price of our common stock exceeded the 130% of the conversion price for the required period, thus allowing the 2010 Convertible Notes to continue to be convertible at the holder’s option through August 31, 2016. Accordingly, as of September 30, 2016, we classified the $35 million principal amount of the 2010 Convertible Notes as a current liability and reclassified the difference between the principal amount payable in cash upon conversion and the total settlement value of the 2010 Convertible Notes, or the intrinsic value of the conversion obligation, of approximately $29 million from stockholders’ equity to current portion of long-term debt conversion obligation on our Balance Sheet.

Upon any conversion of the 2010 Convertible Notes, we will settle our conversion obligation as follows: (i) we are required to pay cash for 100% of the par value of the 2010 Convertible Notes that are converted; and (ii) to the extent the value of our conversion obligation exceeds the par value, we can satisfy the remaining conversion obligation in our common stock, cash or any combination of our common stock and cash, at our discretion.
