Debt Disclosure [Abstract]
Debt	Debt Chapter 11 Proceedings The Chapter 11 filings constituted an event of default with respect to the Company’s existing debt obligations. As a result of the Chapter 11 filings, the obligations arising under the Company's pre-petition senior credit facility, Senior Secured Notes, Senior Unsecured Notes and Convertible Senior Unsecured Notes became immediately due and payable, but the enforcement of any obligations thereunder was automatically stayed as a result of the Chapter 11 filings. Reclassification of Debt. The balance outstanding under the senior credit facility of $448.9 million, par value of the Senior Secured Notes of $1.3 billion, par value of the Senior Unsecured Notes of $2.2 billion and par value of the Convertible Senior Unsecured Notes of $87.6 million have been reclassified as liabilities subject to compromise on the accompanying unaudited condensed consolidated balance sheet at June 30, 2016. Additionally, a non-cash charge to write off all of the related unamortized debt issuance costs and associated discounts and premiums of approximately $158.6 million and the fair value of associated debt derivatives of $9.8 million as of May 16, 2016 related to the Company's debt is included in reorganization items in the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016, as discussed in Note 1. See Note 5 for the fair values and carrying values of the senior notes outstanding at June 30, 2016 and December 31, 2015, respectively. As of December 31, 2015, there were no amounts outstanding under the senior credit facility, and the carrying values of the senior notes were net of unamortized discounts, premiums, and deferred costs of $342.6 million, and included the fair value of debt derivatives of $32.3 million. Senior Credit Facility The Company’s filing of the Bankruptcy Petitions constitutes an event of default that accelerated its obligations under the senior credit facility. Due to the Chapter 11 proceedings, however, most acts to exercise remedies under the Company’s credit facility, including those related to defaults of various financial covenants and ratios, were stayed as of May 16, 2016, the date of the Chapter 11 petition filing, and continue to be stayed. No further funds are available to the Company under the credit facility. The terms of the senior credit facility contain certain financial covenants, including maintenance of agreed upon levels for the (a) ratio of total secured debt under the senior credit facility to earnings before interest, taxes, depreciation and amortization (“EBITDA”), which could not exceed 2.00:1.00 at each quarter end and (b) ratio of current assets to current liabilities, which must be at least 1.0:1.0 at each quarter end. For the purpose of the current ratio calculation, any amounts available to be drawn under the senior credit facility are included in current assets, and unrealized assets and liabilities resulting from mark-to-market adjustments on the Company’s commodity derivative contracts are disregarded. The senior credit facility matures by its terms on the earlier of March 2, 2020 and 91 days prior to the earliest date of any maturity under or mandatory offer to repurchase the Company’s currently outstanding notes. The senior credit facility also contains various covenants that limit the ability of the Company and certain of its subsidiaries to: grant certain liens; make certain loans and investments; make distributions; redeem stock; redeem or prepay debt; merge or consolidate with or into a third party; or engage in certain asset dispositions, including a sale of all or substantially all of the Company’s assets. The terms of the senior credit facility allow the Company to redeem or purchase outstanding Senior Unsecured Notes for up to $275.0 million in cash subject to certain limitations. Additionally, the senior credit facility limits the ability of the Company and certain of its subsidiaries to incur additional indebtedness with certain exceptions. See Note 1 for information regarding the Company’s Bankruptcy Petitions and the Chapter 11 proceedings. The obligations under the senior credit facility are guaranteed by certain Company subsidiaries and are required to be secured by first priority liens on all shares of capital stock of certain of the Company’s material present and future subsidiaries, all of the Company’s intercompany debt, and certain of the Company’s other assets, including proved oil, natural gas and NGL reserves representing at least 80.0% of the discounted present value (as defined in the senior credit facility) of proved oil, natural gas and NGL reserves of the Company. At the Company’s election, interest under the senior credit facility, as amended, is determined by reference to (a) the ICE Benchmark Administration Limited LIBOR (“LIBOR”) plus an applicable margin between 1.750% and 2.750% per annum or (b) the “base rate,” which is the highest of (i) the federal funds rate plus 0.5%, (ii) the prime rate published by Royal Bank of Canada under the senior credit facility or (iii) the one-month Eurodollar rate (as defined in the senior credit facility) plus 1.00% per annum, plus, in each case under scenario (b), an applicable margin between 0.750% and 1.750% per annum. Interest is payable quarterly for base rate loans and at the applicable maturity date for LIBOR loans, except that if the interest period for a LIBOR loan is six months or longer, interest is paid at the end of each three-month period. Quarterly, the Company pays commitment fees assessed at an annual rate of 0.5% on any available portion of the senior credit facility. On March 11, 2016, the administrative agent notified the Company that the lenders had elected to reduce the borrowing base to $340.0 million from $500.0 million pursuant to a special redetermination. On April 20, 2016, the Company submitted for consideration by its lenders additional properties to serve as collateral under the senior credit facility to support a borrowing base of $500.0 million. On May 11, 2016, in connection with the execution of the RSA and in exchange for waivers from the requisite percentage of lenders with respect to certain specified defaults and events of defaults under the senior credit facility, the Company permanently repaid $40.0 million of borrowings to the lenders, which payment correspondingly reduced the lenders’ commitments. See Note 1 for further discussion of the senior credit facility and the plan of reorganization. The senior credit facility had $448.9 million drawn at June 30, 2016 and had $10.2 million in outstanding letters of credit. Additionally, at June 30, 2016, the Company had incurred $1.3 billion in junior lien debt subject to an intercreditor agreement as a result of the issuance of Senior Secured Notes in June 2015 and the PGC Senior Secured Notes in October 2015. Senior Secured Notes The Company issued $1.25 billion of 8.75% Senior Secured Notes due 2020 in June 2015. Net proceeds from the issuance were approximately $1.21 billion after deducting offering expenses, a portion of which was used to repay amounts outstanding at that time under the Company’s senior credit facility. The Senior Secured Notes were issued to qualified institutional buyers eligible under Rule 144A of the Securities Act and to persons outside the United States under Regulation S of the Securities Act. Additionally, the Company issued $78.0 million par value of the PGC Senior Secured Notes in conjunction with the acquisition of and termination of a gathering agreement with PGC in October 2015. Because the PGC Senior Secured Notes were issued as partial consideration for the acquisition and termination, these notes were recorded at fair value of approximately $50.3 million, which included mandatory prepayment feature liabilities and a discount. Fair value at issuance was determined based upon the then-current market value of the Senior Secured Notes. The unamortized portions of the discount and the carrying value of the mandatory prepayment feature as of the date of the Chapter 11 filings, May 16, 2016, were written off to reorganization items on the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016 as noted above. The Company accrued interest on its Senior Secured Notes at a fixed rate of 8.75% prior to the Chapter 11 filings, with no interest accrued subsequent to the filings. The Senior Secured Notes are by their terms redeemable, in whole or in part, prior to their maturity at specified redemption prices and are jointly and severally guaranteed unconditionally, in full, on a second-priority secured basis by certain of the Company’s wholly owned subsidiaries. The Senior Secured Notes are secured by second-priority liens on all of the Company’s assets that secure the senior credit facility on a first-priority basis; provided, however, the security interest in those assets that secure the Senior Secured Notes and the guarantees are contractually subordinated to liens thereon that secure the credit facility and certain other permitted indebtedness. Consequently, the Senior Secured Notes and the guarantees are effectively subordinated to the credit facility and such other indebtedness to the extent of the value of such assets. Maturity Date and Mandatory Prepayment Feature. Pursuant to the indenture, the Senior Secured Notes mature on June 1, 2020; provided, however, that if on October 15, 2019, the aggregate outstanding principal amount of the unsecured 8.75% Senior Notes due 2020 exceeds $100.0 million, the Senior Secured Notes mature on October 16, 2019. See further discussion of the mandatory prepayment feature Note 4 and Note 7, which with respect to the PGC Senior Secured Notes was an embedded derivative that was accounted for separately from these notes, prior to being written-off to reorganization items on the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016, as discussed in Note 1. Indenture. The indenture governing the Senior Secured Notes contains covenants that restrict the Company’s ability to take a variety of actions, including limitations on the payment of dividends, incurrence of indebtedness, create liens, enter into consolidations or mergers, purchase or redeem stock or subordinated or unsecured indebtedness, certain dispositions and transfers of assets, transactions with related parties, make investments and refinance certain indebtedness. The Company’s filing of the Bankruptcy Petitions constitutes an event of default that accelerated the Company’s obligations under its Senior Secured Notes. Under the Bankruptcy Code, the creditors under these debt agreements are stayed from taking any action against the Company as a result of an event of default. See Note 1 for additional details about the Company’s Bankruptcy Petitions and the Chapter 11 proceedings. Senior Unsecured Notes The Company accrued interest on its Senior Unsecured Notes at a fixed rate through the date of the Chapter 11 filings, with no interest accrued subsequent to the filings. The Senior Unsecured Notes are by their terms redeemable, in whole or in part, prior to their maturity at specified redemption prices and are jointly and severally guaranteed unconditionally, in full, on an unsecured basis by certain of the Company’s wholly owned subsidiaries. See Note 14 for condensed financial information of the subsidiary guarantors. Certain of the Senior Unsecured Notes were issued at a discount or a premium. Prior to the Chapter 11 filings, the discount or premium was amortized to interest expense over the term of the respective series of Senior Unsecured Notes. The unamortized portions of the discount or premium as of the date of the Chapter 11 filings, May 16, 2016, were written off to reorganization items on the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016 as noted above. The unamortized portion of the debt issuance costs associated with the Senior Unsecured Notes as of the date of the Chapter 11 filings, May 16, 2016, was written off to reorganization items on the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016 as noted above. Indentures. Each of the indentures governing the Company’s Senior Unsecured Notes contains covenants that restrict the Company’s ability to take a variety of actions, including limitations on the incurrence of indebtedness, payment of dividends, investments, asset sales, certain asset purchases, transactions with related parties and consolidations or mergers. The Company’s filing of the Bankruptcy Petitions constitutes an event of default that accelerated the Company’s obligations under its Senior Unsecured Notes. Under the Bankruptcy Code, the creditors under these debt agreements are stayed from taking any action against the Company as a result of an event of default. See Note 1 for additional details about the Company’s Bankruptcy Petitions and the Chapter 11 proceedings. Convertible Senior Unsecured Notes The Convertible Senior Unsecured Notes were issued in conjunction with exchanges and repurchases of Senior Unsecured Notes that took place in August and October 2015. The Convertible Senior Unsecured Notes are guaranteed by the same guarantors that guarantee the Senior Unsecured Notes and are subject to covenants and bear payment terms substantially identical to those of the corresponding series of Senior Unsecured Notes of similar tenor, other than the conversion features, described further below, and the extension of the final maturity by one day. The Company accrued interest on its Convertible Senior Unsecured Notes at a fixed rate through the date of the Chapter 11 filings, with no interest accrued subsequent to the filings. The transactions were determined to be an extinguishment of each of the Senior Unsecured Notes exchanged. As such, the newly-issued Convertible Senior Unsecured Notes were recorded at fair value on the date of issuance. The Company’s filing of the Bankruptcy Petitions constitutes an event of default that accelerated the Company’s obligations under its Convertible Senior Unsecured Notes. Under the Bankruptcy Code, the creditors under these debt agreements are stayed from taking any action against the Company as a result of an event of default, and further conversions of the Convertible Senior Unsecured Notes into shares of the Company’s common stock were also stayed. See Note 1 for additional details about the Company’s Bankruptcy Petitions and the Chapter 11 Cases. Conversions to Common Stock. During the six-month period ended June 30, 2016, holders of $200.5 million aggregate principal amount ($67.4 million net of discount and including holders’ conversion feature) of 8.125% Convertible Senior Notes due 2022 and $31.6 million aggregate principal amount ($10.4 million net of discount and holders’ conversion feature) of 7.5% Convertible Senior Notes due 2023 exercised conversion options applicable to those notes, resulting in the issuance of approximately 84.4 million shares of Company common stock and aggregate cash payments of $33.5 million for accrued interest and early conversion payments. The conversions resulted in a gain on extinguishment of debt totaling $41.3 million, including the write off of $4.3 million of net unamortized debt issuance costs, which is included in other income on the unaudited condensed consolidated statement of operations for the six-month period ended June 30, 2016. There were no conversions during the three-month period ended June 30, 2016.

Debt

Chapter 11 Proceedings

The Chapter 11 filings constituted an event of default with respect to the Company’s existing debt obligations. As a result of the Chapter 11 filings, the obligations arising under the Company's pre-petition senior credit facility, Senior Secured Notes, Senior Unsecured Notes and Convertible Senior Unsecured Notes became immediately due and payable, but the enforcement of any obligations thereunder was automatically stayed as a result of the Chapter 11 filings.

Reclassification of Debt. The balance outstanding under the senior credit facility of $448.9 million, par value of the Senior Secured Notes of $1.3 billion, par value of the Senior Unsecured Notes of $2.2 billion and par value of the Convertible Senior Unsecured Notes of $87.6 million have been reclassified as liabilities subject to compromise on the accompanying unaudited condensed consolidated balance sheet at June 30, 2016. Additionally, a non-cash charge to write off all of the related unamortized debt issuance costs and associated discounts and premiums of approximately $158.6 million and the fair value of associated debt derivatives of $9.8 million as of May 16, 2016 related to the Company's debt is included in reorganization items in the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016, as discussed in Note 1.

See Note 5 for the fair values and carrying values of the senior notes outstanding at June 30, 2016 and December 31, 2015, respectively. As of December 31, 2015, there were no amounts outstanding under the senior credit facility, and the carrying values of the senior notes were net of unamortized discounts, premiums, and deferred costs of $342.6 million, and included the fair value of debt derivatives of $32.3 million.

Senior Credit Facility

The Company’s filing of the Bankruptcy Petitions constitutes an event of default that accelerated its obligations under the senior credit facility. Due to the Chapter 11 proceedings, however, most acts to exercise remedies under the Company’s credit facility, including those related to defaults of various financial covenants and ratios, were stayed as of May 16, 2016, the date of the Chapter 11 petition filing, and continue to be stayed. No further funds are available to the Company under the credit facility.

The terms of the senior credit facility contain certain financial covenants, including maintenance of agreed upon levels for the (a) ratio of total secured debt under the senior credit facility to earnings before interest, taxes, depreciation and amortization (“EBITDA”), which could not exceed 2.00:1.00 at each quarter end and (b) ratio of current assets to current liabilities, which must be at least 1.0:1.0 at each quarter end. For the purpose of the current ratio calculation, any amounts available to be drawn under the senior credit facility are included in current assets, and unrealized assets and liabilities resulting from mark-to-market adjustments on the Company’s commodity derivative contracts are disregarded. The senior credit facility matures by its terms on the earlier of March 2, 2020 and 91 days prior to the earliest date of any maturity under or mandatory offer to repurchase the Company’s currently outstanding notes.

The senior credit facility also contains various covenants that limit the ability of the Company and certain of its subsidiaries to: grant certain liens; make certain loans and investments; make distributions; redeem stock; redeem or prepay debt; merge or consolidate with or into a third party; or engage in certain asset dispositions, including a sale of all or substantially all of the Company’s assets. The terms of the senior credit facility allow the Company to redeem or purchase outstanding Senior Unsecured Notes for up to $275.0 million in cash subject to certain limitations. Additionally, the senior credit facility limits the ability of the Company and certain of its subsidiaries to incur additional indebtedness with certain exceptions. See Note 1 for information regarding the Company’s Bankruptcy Petitions and the Chapter 11 proceedings.

The obligations under the senior credit facility are guaranteed by certain Company subsidiaries and are required to be secured by first priority liens on all shares of capital stock of certain of the Company’s material present and future subsidiaries, all of the Company’s intercompany debt, and certain of the Company’s other assets, including proved oil, natural gas and NGL reserves representing at least 80.0% of the discounted present value (as defined in the senior credit facility) of proved oil, natural gas and NGL reserves of the Company.

At the Company’s election, interest under the senior credit facility, as amended, is determined by reference to (a) the ICE Benchmark Administration Limited LIBOR (“LIBOR”) plus an applicable margin between 1.750% and 2.750% per annum or (b) the “base rate,” which is the highest of (i) the federal funds rate plus 0.5%, (ii) the prime rate published by Royal Bank of Canada under the senior credit facility or (iii) the one-month Eurodollar rate (as defined in the senior credit facility) plus 1.00% per annum, plus, in each case under scenario (b), an applicable margin between 0.750% and 1.750% per annum. Interest is payable quarterly for base rate loans and at the applicable maturity date for LIBOR loans, except that if the interest period for a LIBOR loan is six months or longer, interest is paid at the end of each three-month period. Quarterly, the Company pays commitment fees assessed at an annual rate of 0.5% on any available portion of the senior credit facility.

On March 11, 2016, the administrative agent notified the Company that the lenders had elected to reduce the borrowing base to $340.0 million from $500.0 million pursuant to a special redetermination. On April 20, 2016, the Company submitted for consideration by its lenders additional properties to serve as collateral under the senior credit facility to support a borrowing base of $500.0 million. On May 11, 2016, in connection with the execution of the RSA and in exchange for waivers from the requisite percentage of lenders with respect to certain specified defaults and events of defaults under the senior credit facility, the Company permanently repaid $40.0 million of borrowings to the lenders, which payment correspondingly reduced the lenders’ commitments. See Note 1 for further discussion of the senior credit facility and the plan of reorganization.

The senior credit facility had $448.9 million drawn at June 30, 2016 and had $10.2 million in outstanding letters of credit. Additionally, at June 30, 2016, the Company had incurred $1.3 billion in junior lien debt subject to an intercreditor agreement as a result of the issuance of Senior Secured Notes in June 2015 and the PGC Senior Secured Notes in October 2015.

Senior Secured Notes

The Company issued $1.25 billion of 8.75% Senior Secured Notes due 2020 in June 2015. Net proceeds from the issuance were approximately $1.21 billion after deducting offering expenses, a portion of which was used to repay amounts outstanding at that time under the Company’s senior credit facility. The Senior Secured Notes were issued to qualified institutional buyers eligible under Rule 144A of the Securities Act and to persons outside the United States under Regulation S of the Securities Act.

Additionally, the Company issued $78.0 million par value of the PGC Senior Secured Notes in conjunction with the acquisition of and termination of a gathering agreement with PGC in October 2015. Because the PGC Senior Secured Notes were issued as partial consideration for the acquisition and termination, these notes were recorded at fair value of approximately $50.3 million, which included mandatory prepayment feature liabilities and a discount. Fair value at issuance was determined based upon the then-current market value of the Senior Secured Notes. The unamortized portions of the discount and the carrying value of the mandatory prepayment feature as of the date of the Chapter 11 filings, May 16, 2016, were written off to reorganization items on the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016 as noted above.

The Company accrued interest on its Senior Secured Notes at a fixed rate of 8.75% prior to the Chapter 11 filings, with no interest accrued subsequent to the filings. The Senior Secured Notes are by their terms redeemable, in whole or in part, prior to their maturity at specified redemption prices and are jointly and severally guaranteed unconditionally, in full, on a second-priority secured basis by certain of the Company’s wholly owned subsidiaries.

The Senior Secured Notes are secured by second-priority liens on all of the Company’s assets that secure the senior credit facility on a first-priority basis; provided, however, the security interest in those assets that secure the Senior Secured Notes and the guarantees are contractually subordinated to liens thereon that secure the credit facility and certain other permitted indebtedness. Consequently, the Senior Secured Notes and the guarantees are effectively subordinated to the credit facility and such other indebtedness to the extent of the value of such assets.

Maturity Date and Mandatory Prepayment Feature. Pursuant to the indenture, the Senior Secured Notes mature on June 1, 2020; provided, however, that if on October 15, 2019, the aggregate outstanding principal amount of the unsecured 8.75% Senior Notes due 2020 exceeds $100.0 million, the Senior Secured Notes mature on October 16, 2019. See further discussion of the mandatory prepayment feature Note 4 and Note 7, which with respect to the PGC Senior Secured Notes was an embedded derivative that was accounted for separately from these notes, prior to being written-off to reorganization items on the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016, as discussed in Note 1.

Indenture. The indenture governing the Senior Secured Notes contains covenants that restrict the Company’s ability to take a variety of actions, including limitations on the payment of dividends, incurrence of indebtedness, create liens, enter into consolidations or mergers, purchase or redeem stock or subordinated or unsecured indebtedness, certain dispositions and transfers of assets, transactions with related parties, make investments and refinance certain indebtedness. The Company’s filing of the Bankruptcy Petitions constitutes an event of default that accelerated the Company’s obligations under its Senior Secured Notes. Under the Bankruptcy Code, the creditors under these debt agreements are stayed from taking any action against the Company as a result of an event of default. See Note 1 for additional details about the Company’s Bankruptcy Petitions and the Chapter 11 proceedings.

Senior Unsecured Notes

The Company accrued interest on its Senior Unsecured Notes at a fixed rate through the date of the Chapter 11 filings, with no interest accrued subsequent to the filings. The Senior Unsecured Notes are by their terms redeemable, in whole or in part, prior to their maturity at specified redemption prices and are jointly and severally guaranteed unconditionally, in full, on an unsecured basis by certain of the Company’s wholly owned subsidiaries. See Note 14 for condensed financial information of the subsidiary guarantors. Certain of the Senior Unsecured Notes were issued at a discount or a premium. Prior to the Chapter 11 filings, the discount or premium was amortized to interest expense over the term of the respective series of Senior Unsecured Notes. The unamortized portions of the discount or premium as of the date of the Chapter 11 filings, May 16, 2016, were written off to reorganization items on the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016 as noted above.

The unamortized portion of the debt issuance costs associated with the Senior Unsecured Notes as of the date of the Chapter 11 filings, May 16, 2016, was written off to reorganization items on the accompanying unaudited condensed consolidated statements of operations for the three and six-month periods ended June 30, 2016 as noted above.

Indentures. Each of the indentures governing the Company’s Senior Unsecured Notes contains covenants that restrict the Company’s ability to take a variety of actions, including limitations on the incurrence of indebtedness, payment of dividends, investments, asset sales, certain asset purchases, transactions with related parties and consolidations or mergers. The Company’s filing of the Bankruptcy Petitions constitutes an event of default that accelerated the Company’s obligations under its Senior Unsecured Notes. Under the Bankruptcy Code, the creditors under these debt agreements are stayed from taking any action against the Company as a result of an event of default. See Note 1 for additional details about the Company’s Bankruptcy Petitions and the Chapter 11 proceedings.

Convertible Senior Unsecured Notes

The Convertible Senior Unsecured Notes were issued in conjunction with exchanges and repurchases of Senior Unsecured Notes that took place in August and October 2015. The Convertible Senior Unsecured Notes are guaranteed by the same guarantors that guarantee the Senior Unsecured Notes and are subject to covenants and bear payment terms substantially identical to those of the corresponding series of Senior Unsecured Notes of similar tenor, other than the conversion features, described further below, and the extension of the final maturity by one day. The Company accrued interest on its Convertible Senior Unsecured Notes at a fixed rate through the date of the Chapter 11 filings, with no interest accrued subsequent to the filings. The transactions were determined to be an extinguishment of each of the Senior Unsecured Notes exchanged. As such, the newly-issued Convertible Senior Unsecured Notes were recorded at fair value on the date of issuance.

The Company’s filing of the Bankruptcy Petitions constitutes an event of default that accelerated the Company’s obligations under its Convertible Senior Unsecured Notes. Under the Bankruptcy Code, the creditors under these debt agreements are stayed from taking any action against the Company as a result of an event of default, and further conversions of the Convertible Senior Unsecured Notes into shares of the Company’s common stock were also stayed. See Note 1 for additional details about the Company’s Bankruptcy Petitions and the Chapter 11 Cases.

Conversions to Common Stock. During the six-month period ended June 30, 2016, holders of $200.5 million aggregate principal amount ($67.4 million net of discount and including holders’ conversion feature) of 8.125% Convertible Senior Notes due 2022 and $31.6 million aggregate principal amount ($10.4 million net of discount and holders’ conversion feature) of 7.5% Convertible Senior Notes due 2023 exercised conversion options applicable to those notes, resulting in the issuance of approximately 84.4 million shares of Company common stock and aggregate cash payments of $33.5 million for accrued interest and early conversion payments. The conversions resulted in a gain on extinguishment of debt totaling $41.3 million, including the write off of $4.3 million of net unamortized debt issuance costs, which is included in other income on the unaudited condensed consolidated statement of operations for the six-month period ended June 30, 2016. There were no conversions during the three-month period ended June 30, 2016.
