In connection with the issuance of the Series A Convertible Preferred Stock, the Company incurred direct and incremental expenses of $26 million, including financial advisory fees, closing costs, legal expenses and other offering-related expenses. These direct and incremental expenses reduced the Series A Convertible Preferred Stock, and will be accreted through retained earnings as a deemed dividend from the date of issuance through the first possible known redemption date, March 16, 2024. Holders of Series A Convertible Preferred Stock are entitled to a cumulative dividend at the rate of 5.5% per annum, payable quarterly in arrears. During the three months ended June 30, 2018 and 2017, the Company paid dividends-in-kind of $12 million and $11 million, respectively, associated with the Series A Convertible Preferred Stock. During the six months ended June 30, 2018 and 2017, the Company paid dividends-in-kind of $23 million, respectively, associated with the Series A Convertible Preferred Stock. As of June 30, 2018 and December 31, 2017, the Company had accrued dividends of $3 million, respectively, associated with the Series A Convertible Preferred Stock. There were no cash dividends declared during the three and six months ended June 30, 2018 or 2017. The Series A Convertible Preferred Stock is convertible at the option of the holders at any time into shares of common stock at a conversion price of $30.00 per share, or a conversion rate of 33.333 shares of common stock per share of Series A Convertible Preferred Stock. Under the Investment Agreement, Blackstone agreed not to sell or otherwise transfer its shares of Series A Convertible Preferred Stock (or any shares of common stock issued upon conversion thereof) without the Company’s consent until June 4, 2017. In March 2017, we provided Blackstone with an early release from this lock-up, allowing Blackstone to sell approximately 49% of its shares of Series A Convertible Preferred Stock, and in return, Blackstone agreed to amend the Investment Agreement to extend the lock-up on the remaining 51% of its shares of Series A Convertible Preferred Stock for six months until December 1, 2017. In connection with the early release of the lock-up, Blackstone offered for sale 342,000 shares of Series A Convertible Preferred Stock in an underwritten public offering. In addition, Blackstone converted 90,000 shares of Series A Convertible Preferred Stock into shares of our common stock and we repurchased those shares of common stock for $48.47 per share. The underwritten offering and the stock repurchase were consummated on March 17, 2017. The repurchase of the common shares immediately upon conversion is considered a redemption of the related preferred shares. As a result, the excess of the fair value of consideration transferred over the carrying value, of $58 million, was included as a deemed dividend in adjusting the income from common stockholders in calculating earnings per share for the six months ended June 30, 2017. Additionally, we determined that the changes to the lock-up period were considered a modification of the Series A Convertible Preferred Stock. The impact of the modification, calculated as the difference in the fair value immediately before and immediately after the changes, of $4 million, was included as a deemed dividend in adjusting the income from common stockholders in calculating earnings per share for the six months ended June 30, 2017. This adjustment was recorded as an increase to the Series A Convertible Preferred Shares and will reduce the accretion of the direct and incremental expenses associated with the original offering as described above. Refer to Note 12. Earnings per Share for additional discussion. As of June 30, 2018 and December 31, 2017, the maximum number of common shares that could be required to be issued upon conversion of the outstanding shares of Series A Convertible Preferred Stock was 28.2 million and 27.5 million shares, respectively.
