| Organization | Organization Nature of Operations Hornbeck Offshore Services, Inc., or the Company, was incorporated in the state of Delaware in 1997. The Company, through its subsidiaries, operates offshore supply vessels, or OSVs, multi-purpose support vessels, or MPSVs, and a shore-base facility to provide logistics support and specialty services to the offshore oil and gas exploration and production industry, primarily in the U.S. Gulf of Mexico, or GoM, Latin America and select international markets. All significant intercompany accounts and transactions have been eliminated. Certain reclassifications associated with discontinued operations have been made to prior period results to conform to current year presentation. As discussed further in Note 13, the Company sold substantially all of its Downstream assets in August 2013. |

| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Revenue Recognition The Company charters its OSVs and MPSVs to clients under time charters based on a daily rate of hire and recognizes revenue as earned on a daily basis during the contract period of the specific vessel. Deferred revenue represents payments received from customers or billings submitted to customers in advance of providing vessel access through time charters or other contracted arrangements. Cash and Cash Equivalents Cash and cash equivalents consist of all highly liquid investments in money market funds, deposits and investments available for current use with an initial maturity of three months or less. Accounts Receivable Accounts receivable consists of trade receivables net of reserves and amounts to be rebilled to customers. Property, Plant and Equipment Property, plant and equipment is recorded at cost. Depreciation and amortization of equipment and leasehold improvements are computed using the straight-line method based on the estimated useful lives of the related assets. Major modifications and improvements, which extend the useful life of the vessel, are capitalized and amortized over the remaining useful life of the vessel. Gains and losses from retirements or other dispositions are recognized as incurred. Salvage values for new generation marine equipment are estimated to be 25% of the originally recorded cost. The estimated useful lives by classification are as follows:
See “Impairment of Long-Lived Assets” below for more information. Deferred Charges The Company’s vessels are required by regulation to be recertified after certain periods of time. The Company defers the drydocking expenditures incurred due to regulatory marine inspections and amortizes the costs on a straight-line basis over the period to be benefited from such expenditures (generally 30 months). Financing charges are amortized over the term of the related debt. Deferred charges also include prepaid lease expenses related to the Company’s shore-base port facility. Such prepaid lease expenses are being amortized on a straight-line basis over the effective remaining term of the lease. Mobilization Costs The Company incurs mobilization costs to transit its vessels to and from certain regions and/or for long-term contracts. These costs, which are typically expensed as incurred, include, but are not limited to, fuel, crew wages, vessel modification and pre-positioning expenses, materials and supplies and importation taxes. The Company incurred mobilization costs of $1.5 million, $2.7 million and $1.4 million during 2014, 2013 and 2012, respectively, associated with the mobilization and pre-positioning of vessels to or from different geographic locations. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using currently enacted tax rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The provision for income taxes includes provisions for federal, state and foreign income taxes. Interest and penalties relating to uncertain tax positions are recorded as general and administrative expenses. In addition, the Company provides a valuation allowance for deferred tax assets if it is more likely than not that such items will either expire before the Company is able to realize the benefit or the future deductibility is uncertain. As a result of the sale of the Downstream segment during the third quarter of 2013, the Company believed that certain state operating loss carryforwards would not be realizable and thus recorded a valuation allowance of $0.9 million for the year ended December 31, 2013. During the third quarter of 2014, the Company recorded an additional $0.1 million related to these state operating losses. No valuation allowances were recorded for the year ended December 31, 2012. Use of Estimates The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Legal Liabilities In the ordinary course of business, the Company may become party to lawsuits, administrative proceedings, or governmental investigations. These matters may involve large or unspecified damages or penalties that may be sought from the Company and may require years to resolve. The Company records a liability related to a loss contingency to such legal matters in accrued liabilities if the Company determines the loss to be both probable and estimable. The liability is recorded for an amount that is management’s best estimate of the loss, or when a best estimate cannot be made, the minimum loss amount of a range of possible outcomes. Significant judgment is required in estimating such liabilities, the results of which can vary significantly from the actual outcomes of lawsuits, administrative proceedings or governmental investigations. Concentration of Credit Risk Customers are primarily major and independent, domestic and international, oil and oil service companies, as well as national oil companies and the U.S. military. The Company’s customers are granted credit on a short-term basis and related credit risks are considered minimal. The Company usually does not require collateral. The Company provides an estimate for uncollectible accounts based primarily on management’s judgment using the relative age of customer balances, historical losses, current economic conditions and individual evaluations of each customer to make adjustments to the allowance for doubtful accounts. The following table represents the allowance for doubtful accounts (in thousands):
Impairment of Long-Lived Assets When events or circumstances indicate that the carrying amount of long-lived assets to be held and used or intangible assets might not be recoverable, the expected future undiscounted cash flows from the assets are estimated and compared with the carrying amount of the assets. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the assets, an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the assets with their carrying amounts. Fair value is determined based on discounted cash flow or appraised values, as appropriate. No triggering events occurred in 2014, 2013 or 2012 and the Company did not record any impairment losses related to its long-lived assets during these periods. The Company's review gave consideration to the current market conditions, which include the recent commodity price decline and reduction in certain projected 2015 capital budgets for its customers. While the Company expects this environment to have a negative impact on vessel utilization and dayrates, the Company views the deepwater and ultra deepwater projects of its customers, which is the principal market for its vessel fleet, to be somewhat insulated from commodity price cycles compared to onshore shale and shallow shelf offshore exploration and production activities. However, continued commodity price declines or protracted extensions of the current price cycle could result in additional delays or cancellations of deepwater projects, which is a major indicator of fleet utilization. Should this occur, the Company will update its analysis of whether a triggering event has occurred. Recent Accounting Pronouncements On May 28, 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update (ASU) No. 2014-09, "Revenue from Contracts with Customers" (Topic 606), which supersedes the revenue recognition requirements in FASB Accounting Standard Codification (ASC) Topic 605, "Revenue Recognition." ASU No. 2014-09 requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 requires retrospective application and will be effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early application is not permitted. The Company is evaluating the effect of this new standard on its financial statements. |

Diluted earnings per common share was calculated by dividing net income by the weighted average number of common shares outstanding during the year plus the effect of dilutive securities. Weighted average number of common shares outstanding was calculated by using the sum of the shares determined on a daily basis divided by the number of days in the period.

In November 2011, the Company announced, and has since expanded, its fifth OSV newbuild program. The program consists of vessel construction contracts with three domestic shipyards to build four 300 class OSVs, five 310 class OSVs, ten 320 class OSVs and five 310 class MPSVs. As of December 31, 2014, the Company has placed 14 vessels in-service under its fifth newbuild program. Subsequent to year-end, the Company placed in service two additional vessels under such program. The eight remaining vessels under this 24-vessel domestic newbuild program are currently expected to be placed in service as follows: five in the remainder of 2015 and three in 2016. Based on current contracts and internal estimates,the aggregate total cost of this program, before construction period interest, is expected to be approximately $1,265.0 million. From the inception of this program through December 31, 2014, the Company has incurred $1,032.4 million, or 81.6%, of total expected project costs. In February 2015, the Company agreed to sell four of its 250EDF class OSVs currently chartered to the U.S. Navy and to subsequently operate such vessels for the Navy under an operations and maintenance (O&M) contract, which contains an initial term and annual renewal options spanning a 10-year operating period. These arrangements are subject to final documentation. In order for the Navy to continue receiving the unique capabilities of these vessels, Congress has required their purchase from the Company, provided an agreement could be reached. The details of this transaction are currently being finalized and are expected to be completed in late-February with the O&M contract beginning immediately upon closing of each respective vessel sale. However, the currently negotiated sales price for the vessels is greater than their gross book values as of December 31, 2014. |

| Long-Term Debt | Long-Term Debt As of the dates indicated below, the Company had the following outstanding long-term debt (in thousands):
The table below summarizes the Company's cash interest payments (in thousands):
Annual maturities of debt, excluding the potential effects of conditions discussed in Convertible Senior Notes, during each year ending December 31, are as follows (in thousands):
2020 Senior Notes On March 2, 2012, the Company issued $375.0 million in aggregate principal amount of 2020 senior notes, governed by an indenture, or the 2012 indenture. The net proceeds to the Company from the offering were approximately $367.4 million, net of transaction costs. The Company used $259.9 million of proceeds on March 16, 2012 to repurchase approximately 84% of its outstanding 2014 senior notes pursuant to its tender offer for such notes. The Company used $49.5 million of proceeds on April 30, 2012 to redeem the remaining 16% of the outstanding 2014 senior notes. The repurchase and redemption of the 2014 senior notes resulted in a loss on early extinguishment of debt of approximately $6.0 million in 2012. The remaining proceeds were used for the construction of vessels under our fifth OSV newbuild program. The 2020 senior notes mature on April 1, 2020 and require semi-annual interest payments at a fixed annual rate of 5.875%, or $11.0 million semi-annually, on April 1 and October 1 of each year until maturity. The effective interest rate on the 2020 senior notes is 6.08%. No principal payments are due until maturity. Pursuant to a registered exchange offer, the 2020 senior notes issued in March 2012 that were initially sold pursuant to a private placement were exchanged by the holders for 2020 senior notes with substantially the same terms, except that the issuance of the 2020 senior notes in the exchange offer was registered under the Securities Act. The original 2020 senior notes and the similar notes exchanged were issued under and are entitled to the benefits of the same 2012 indenture. 2021 Senior Notes On March 14, 2013, the Company issued $450.0 million in aggregate principal amount of 2021 senior notes, governed by an indenture, or the 2013 indenture. The net proceeds to the Company from the offering were approximately $442.4 million, net of estimated transaction costs. The Company used $252.7 million of such proceeds to repurchase approximately 94% of the outstanding 2017 senior notes pursuant to its tender offer for such notes. The Company used approximately $16.6 million of proceeds on May 13, 2013 to redeem the remaining 6% of the outstanding 2017 senior notes. The repurchase and redemption of the 2017 senior notes resulted in a loss on early extinguishment of debt of approximately $25.8 million in 2013. The remaining proceeds have been available for general corporate purposes, which may include funding for the acquisition, construction or retrofit of vessels. The 2021 senior notes mature on March 1, 2021 and require semi-annual interest payments at a fixed annual rate of 5.000%, or $11.3 million due and payable each March 1 and September 1 of each year until maturity, commencing September 1, 2013. The effective interest rate on the new senior notes is 5.21%. No principal payments are due until maturity. Pursuant to a registered exchange offer, the 2021 senior notes issued in March 2013 that were initially sold pursuant to a private placement were exchanged by the holders for 2021 senior notes with substantially the same terms, except that the issuance of the 2021 senior notes in the exchange offer was registered under the Securities Act. The original 2021 senior notes and the similar notes exchanged were issued under and are entitled to the benefits of the same 2013 indenture. The 2020 senior notes and 2021 senior notes are senior unsecured obligations and rank equally in right of payment with other existing and future senior indebtedness and senior in right of payment to any subordinated indebtedness that may be incurred by the Company in the future. The 2020 senior notes and the 2021 senior notes are guaranteed by certain of the Company’s subsidiaries. The guarantees are full and unconditional, joint and several, and all of the Company’s non-guarantor subsidiaries are minor as defined in the Securities and Exchange Commission regulations. Hornbeck Offshore Services, Inc., as the parent company issuer of the 2020 senior notes and the 2021 senior notes, has no independent assets or operations other than its ownership interest in its subsidiaries and affiliates. There are no significant restrictions on the Company’s ability, or the ability of any guarantor, to obtain funds from its subsidiaries by such means as a dividend or loan. The Company may, at its option, redeem all or part of the 2020 senior notes or 2021 senior notes from time to time at specified redemption prices and subject to certain conditions required by the indentures. The Company is permitted under the terms of the indentures to incur additional indebtedness in the future, provided that certain financial conditions set forth in the indentures are satisfied by the Company. 2019 Convertible Senior Notes On August 13, 2012, the Company issued $300.0 million of 2019 convertible senior notes. The 2019 convertible senior notes bear interest at a fixed annual rate of 1.500%, or $2.3 million semi-annually, which started accruing from August 13, 2012, and are payable semi-annually on March 1 and September 1 of each year, commencing on March 1, 2013. The 2019 convertible senior notes mature on September 1, 2019. Because the 2019 convertible senior notes are considered to be cash convertible debt, the Company has separately accounted for the liability and equity components of the 2019 convertible senior notes by allocating the $300.0 million in proceeds from the issuance between the liability component and the embedded conversion option, or the equity component. The allocation was conducted by estimating an interest rate at the time of issuance of the 2019 convertible senior notes for similar debt instruments that do not include an embedded conversion feature. A non-convertible interest rate of 5.75% was used to compute the initial fair value of the liability component of $227.6 million. For purposes of the fair value measurement, the Company determined that the valuation of the 2019 convertible senior notes falls under Level 2 of the fair value hierarchy. The excess of the $300.0 million of proceeds from the issuance of the 2019 convertible senior notes over the $227.6 million initial amount allocated to the liability component, or $72.4 million, was allocated to the embedded conversion option, or equity component. This excess was treated as an imputed original issue discount and is being amortized through interest expense, using the effective interest method, over the seven-year term of the 2019 convertible senior notes, which runs through September 1, 2019. The effective interest rate for these notes is 6.23%. The initial conversion rate of the 2019 convertible senior notes is 18.5718 shares per $1,000 principal amount of notes, which equates to a conversion price of approximately $53.85 per share. The conversion rate was based on the last reported sale price of the Company’s common shares on the New York Stock Exchange of $39.16 on August 7, 2012. The conversion rate will be subject to adjustment in some events but will not be adjusted for accrued interest. In addition, following certain corporate transactions that constitute “fundamental changes” (as defined in the indenture for the 2019 convertible senior notes), the conversion rate will be increased for holders who elect to convert notes in connection with such corporate transactions in certain circumstances. The 2019 convertible senior notes are convertible based on the applicable conversion rate only under the following circumstances:
Upon conversion, the Company will satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election. If the holders of the 2019 convertible senior notes exercise the conversion provisions of the 2019 convertible senior notes and the Company elects to settle such conversions partially in cash (which it presently intends to do at least up to the principal amount of the notes), the Company will need to remit such cash amount to the converting holders. For that reason, in any period during which the 2019 convertible senior notes are convertible as provided above, the Company would classify the entire principal amount of the outstanding 2019 convertible senior notes as a current liability in the respective quarter. This evaluation of the classification of amounts outstanding associated with the 2019 convertible senior notes will occur every calendar quarter. The 2019 convertible senior notes are not redeemable at the option of the Company prior to their maturity. No sinking fund is provided for the 2019 convertible senior notes and the 2019 convertible senior notes are not subject to legal defeasance. If the Company experiences specified types of corporate transactions, including certain change of control events or a de-listing of the Company’s common stock, holders of the 2019 convertible senior notes may require the Company to purchase all or a portion of their 2019 convertible senior notes. Any repurchase of the convertible senior notes pursuant to these provisions will be for cash at a price equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest to, but excluding, the purchase date. In connection with the sale of the 2019 convertible senior notes, the Company entered into convertible senior note hedge transactions with respect to its common stock with affiliates of the initial purchasers of the notes, Barclays, Inc., JP Morgan Chase and Wells Fargo Bank, or the counterparties. Each of the 2019 convertible senior note hedge transactions is a privately-negotiated transaction that is economically equivalent to the purchase of call options on the Company’s common stock with strike prices equal to the conversion price of the 2019 convertible senior notes, and is intended to mitigate dilution to the Company’s stockholders and/or offset cash payment due upon the potential future conversion of the 2019 convertible senior notes. Under the 2019 convertible senior note hedge transactions, subject to customary anti-dilution provisions, the counterparties are required to deliver to the Company the approximate number of shares of the Company’s common stock and/or an amount of cash that the Company is obligated to deliver to the holders of the 2019 convertible senior notes assuming the conversion of such notes. The Company also entered into separate privately-negotiated warrant transactions, whereby the Company sold to each of the counterparties call options to acquire approximately the same number of shares of its common stock underlying the convertible senior note hedge transactions, subject to customary anti-dilution adjustments, at a strike price of $68.53 per share of common stock, which represented a 75.0% premium over the closing price of the Company’s shares of common stock on August 7, 2012. Upon the exercise of the warrants, if the market price of the common stock exceeds the strike price of the warrants on any day within the valuation period, the Company will be required to deliver the corresponding value to the counterparties, at its option in cash or shares of its common stock. The 2019 convertible senior note hedge and warrant transactions are separate and legally distinct instruments that bind the Company and the counterparties and have no binding effect on the holders of the 2019 convertible senior notes. For income tax reporting purposes, the Company has elected to integrate the 2019 convertible senior notes and the note hedge transactions. Integration of the 2019 convertible senior note hedge with the 2019 convertible senior notes creates an in-substance original issue debt discount for income tax reporting purposes and, therefore, the cost of the 2019 convertible senior note hedge is accounted for as interest expense over the term of the 2019 convertible senior notes for income tax reporting purposes. The associated income tax deductions will be recognized in the period that the deduction is taken for income tax reporting purposes. The Company has also treated the proceeds from the sale of warrants as a non-taxable increase in additional paid-in capital in stockholders’ equity. The Company used a portion of the $290.8 million in net proceeds of the 2019 convertible senior notes offering, along with a portion of the $48.2 million in proceeds from the sale of warrants, to fund the $73.0 million cost of convertible senior note hedge transactions. The Company used a portion of the remaining net proceeds of approximately $266.0 million from the sale of the 2019 convertible senior notes and the sale of the warrants to retire its 2026 convertible senior notes, which were converted or redeemed by the Company in November 2013. The Company incurred $9.3 million of fees and other costs related to the issuance of the 2019 convertible senior notes. These fees and other origination costs have been allocated to the liability and equity components of the 2019 convertible senior notes in proportion to their allocated values. Approximately $2.2 million of these fees and other origination costs were recorded as a reduction in additional paid-in capital. The remaining $7.1 million of fees and other costs are being amortized as interest expense over the seven-year term of the 2019 convertible senior notes, which runs through September 1, 2019. The 2019 convertible senior notes are guaranteed by certain of the Company’s subsidiaries. The guarantees are full and unconditional, joint and several, and all of the Company’s non-guarantor subsidiaries are minor as defined in the Securities and Exchange Commission, or Commission, regulations. Hornbeck Offshore Services, Inc., as the parent company issuer of the 2019 convertible senior notes, has no independent assets or operations other than its ownership interest in its subsidiaries and affiliates. There are no significant restrictions on the Company’s ability or the ability of any guarantor to obtain funds from its subsidiaries by such means as a dividend or loan. The 2019 convertible senior notes are general unsecured, senior obligations of the Company, ranking equally in right of payment with all of its existing and future senior indebtedness, including its 2020 and 2021 senior notes. Revolving Credit Facility On February 6, 2015, the Company amended and restated its revolving credit facility. The key changes to the Company’s revolving credit facility were effective commencing with the fiscal quarter ended December 31, 2014 and are noted below:
Other than these key changes, all other definitions and substantive terms in the Company’s credit agreement governing its revolving credit facility were unchanged with the February 2015 amendment and remain in effect through the remaining life of the facility. As of December 31, 2014, there were no amounts drawn under the Company’s $300.0 million revolving credit facility and $0.8 million posted in letters of credit. As of December 31, 2014, the Company was in compliance with all financial covenants contained in its amended revolving credit facility. The credit agreement governing the amended revolving credit facility and the indentures governing the Company’s 2020 senior notes and 2021 senior notes impose certain operating and financial restrictions on the Company. Such restrictions affect, and in many cases limit or prohibit, among other things, the Company’s ability to incur additional indebtedness, make capital expenditures, redeem equity, create liens, sell assets and make dividend or other restricted payments. The Company estimates the fair value of its 2020 senior notes, 2021 senior notes and 2019 convertible senior notes by primarily using quoted market prices. The fair value of the Company’s revolving credit facility, when there are outstanding balances, approximates its carrying value. The face value, carrying value and fair value of the Company’s total debt was $1,125.0 million, $1,073.5 million and $955.0 million, respectively, as of December 31, 2014. Given the observable nature of the inputs to these estimates, the fair values presented for long-term debt have been assigned a Level 2, of the three-level valuation hierarchy. Capitalized Interest Interest expense excludes capitalized interest related to the construction or conversion of vessels in the approximate amount of $33.2 million, $31.2 million, and $11.0 million, for the years ended December 31, 2014, 2013, and 2012, respectively. |

| Stockholders' Equity | Stockholders’ Equity Preferred Stock The Company’s certificate of incorporation authorizes 5.0 million shares of preferred stock. The Board of Directors has the authority to issue preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of such series, without further vote or action by the Company’s stockholders. Stockholder Rights Plan On July 1, 2013, the Company’s Board of Directors implemented a stockholder rights plan establishing one right for each outstanding share of common stock. The rights become exercisable, and transferable apart from the Company’s common stock, 10 business days following a public announcement that a person or group has acquired beneficial ownership of, or has commenced a tender or exchange offer for, 10% or more of the Company’s common stock. This stockholder rights plan is substantially similar to the Company's prior stockholder rights plan that expired on June 17, 2013. Repurchases of Common Stock On October 28, 2014, the Company's Board of Directors authorized the Company to repurchase up to $150.0 million in shares of its common stock using different methods including, but not limited to, open-market purchases, privately negotiated transactions, accelerated share repurchases and Rule 10b5-1 trading plans. The timing and amount of the repurchases will depend on several factors, such as market conditions, applicable legal requirements, available liquidity, the discretion of management and other appropriate factors. The repurchase program does not obligate the Company to acquire any particular amount of common stock and may be modified, suspended or discontinued at any time. As of December 31, 2014, the Company had repurchased and retired 891,396 shares at an average price of $28.05 per share. The repurchased shares cost a total of $25 million and represent roughly 2.5% of the Company's total shares outstanding prior to the commencement of the program.The following table provides information with respect to purchases of common stock under the repurchase program during the year ended December 31, 2014 (in thousands, except for per share data):

As of December 31, 2014, there were 424,587 shares available for future issuance to employees under the incentive compensation plan. The issuance of shares of common stock under the incentive compensation plan has been registered on Form S-8 with the Securities and Exchange Commission. The financial impact of stock-based compensation expense related to the Company’s incentive compensation plan on its operating results are reflected in the table below (in thousands, except for per share data):
The accounting rules also require the benefits of tax deductions in excess of recognized compensation expense to be reported as financing cash flows, rather than as operating cash flows. The Company recorded financing cash flows for such excess tax deductions of approximately $0.0 million, $2.7 million, and $0.9 million for the years ended December 31, 2014, 2013, and 2012, respectively. Net cash proceeds from the exercise of stock options were $1.4 million, $6.2 million, and $1.8 million for the years ended December 31, 2014, 2013, and 2012, respectively. The income tax benefit from stock option exercises and restricted stock vesting was $0.4 million, $4.8 million, and $3.0 million for the respective periods. Stock Options The Company is authorized to grant stock options under its incentive compensation plan in which the purchase price of the stock subject to each option is established as the closing price on the New York Stock Exchange of the Company’s common stock on the date of grant and accordingly is not less than the fair market value of the stock on the date of grant. All options granted expire ten years after the date of grant, have an exercise price equal to or greater than the actual or estimated market price of the Company’s stock on the date of grant and vest over a three-year period. The Company has not granted stock options to any directors, executive officers or employees since 2011. The following table represents the Company’s stock option activity for the year ended December 31, 2014 (in thousands, except per share data and years):
The following table represents the Company’s stock option activity for the year ended December 31, 2013 (in thousands, except per share data and years):

The following table represents the Company’s nonvested stock option activity for the year ended December 31, 2014 (in thousands, except per share data):
As of December 31, 2014, the Company had no unamortized stock-based compensation expense and had recorded approximately $0.1 million of compensation expense during 2014, associated with stock options. Restricted Stock Equity-Settled Restricted Stock The Company’s incentive compensation plan allows the Company to issue restricted stock units, with either performance-based or time-based vesting provisions. The Company has issued two types of performance-based restricted stock unit awards whose vesting is determined by achieving either external or internal performance criteria. For the first type of performance-based restricted stock unit award, or market based award, the number of shares that will ultimately be received by the award recipients at the end of the performance period is dependent upon the Company’s stock price performance relative to a peer group, as defined by the restricted stock unit agreements governing such awards. Compensation expense for such types of awards has historically been measured using a Monte Carlo simulation to project the change in the Company's stock price against a peer group to determine fair value, which is amortized over the vesting period of three years. The actual number of shares that could be received by the award recipients can range from 0% to 200% of the Company’s base share awards depending on the Company’s performance ranking relative to the peer group. This type of performance-based restricted stock unit was granted prior to 2012. The second type of performance-based restricted stock unit award, calculates the shares to be received based on the Company’s achievement of certain internal performance criteria over a three-year period as defined by the restricted stock unit agreement governing such awards. Performance for these types of awards has historically been measured by a number of factors that may differ from year to year, including such examples as the Company achieving a targeted return on invested capital, Upstream operating profit margin, and safety record. The actual number of shares that could be received by the award recipients for the years in question can range from 0% to 150% of the Company’s base share awards depending on the number and/or extent of performance goals attained by the Company. This type of performance-based restricted stock unit was granted in 2012, 2013 and 2014. Compensation expense related to performance-based restricted stock unit awards, which use internal performance criteria, is recognized over the period the restrictions lapse, from one to three years, based on the market price of the Company's stock on the date of grant applied to the shares that are expected to vest. The compensation expense related to time-based restricted stock awards, which is amortized over a one to three-year vesting period, is determined based on the market price of the Company’s stock on the date of grant applied to the total shares that are expected to fully vest. As of December 31, 2014, the Company had unamortized stock-based compensation expense of $10.6 million, which will be recognized on a straight-line basis over the remaining vesting period, or 1.6 years. In addition, the Company has recorded approximately $9.0 million of compensation expense during the year ended December 31, 2014 associated with restricted stock-based unit awards. The following table summarizes the equity-settled restricted stock awards activity during the year ended December 31, 2014 (in thousands, except per share data):
The following table summarizes the equity-settled restricted stock awards activity during the year ended December 31, 2013 (in thousands, except per share data):
The following table summarizes the equity-settled restricted stock awards activity during the year ended December 31, 2012 (in thousands, except per share data):
Cash-Settled Restricted Stock The Company’s incentive compensation plan allows the Company to issue restricted stock units with cash-settled vesting provisions. The compensation expense related to cash-settled phantom restricted stock awards is amortized over a vesting period of up to three years, as applicable, and is determined based on the market price of the Company’s stock on the date of grant applied to the total shares that are expected to fully vest. The cash-settled phantom restricted stock units are re-measured quarterly based on the period-end market price of the Company's common stock and are classified as a liability, due to the settlement of these awards in cash. This type of phantom time-based restricted stock unit was granted in 2014 and 2013. As of December 31, 2014, the Company had unamortized cash-settled phantom compensation expense of $0.9 million, which will be recognized on a straight-line basis over the remaining vesting period, or 1.5 years. In addition, as a result of its stock price decline in 2014, the Company recorded a reduction to compensation expense of approximately $0.1 million during the year ended December 31, 2014 associated with cash-settled phantom awards. The following table summarizes the phantom cash-settled restricted stock awards activity during the year ended December 31, 2014 (in thousands, except per share data):
The following table summarizes the phantom cash-settled restricted stock awards activity during the year ended December 31, 2013 (in thousands, except per share data):

Employee Stock Purchase Plan On May 3, 2005, the Company established the Hornbeck Offshore Services, Inc. 2005 Employee Stock Purchase Plan, or ESPP, which was adopted by the Company’s Board of Directors and approved by the Company’s stockholders. Under the ESPP, the Company is authorized to issue up to 700,000 shares of common stock to eligible employees of the Company and its designated subsidiaries. Employees have the opportunity to purchase shares of the Company’s common stock at periodic intervals through accumulated payroll deductions that will be applied at semi-annual intervals to purchase shares of common stock at a discount from the market price as defined by the ESPP. The ESPP is designed to satisfy the requirements of Section 423 of the Internal Revenue Code of 1986, as amended, and thereby allows participating employees to defer recognition of taxes when purchasing the shares of common stock at a 15% discount under the ESPP. The Company has an effective Registration Statement on Form S-8 with the Commission registering the issuance of shares of common stock under the ESPP. As of December 31, 2014, there were 45,899 shares available for future issuance to employees under the ESPP. The Company has recorded approximately $1.2 million of compensation expense during the year ended December 31, 2014 associated with the ESPP. The fair value of the employees’ stock purchase rights granted under the ESPP was estimated using the Black-Scholes model with the following assumptions for years ended December 31, 2014 and 2013:

Income from continuing operations before income taxes, based on jurisdiction earned, was as follows (in thousands):
At December 31, 2014, the Company had federal tax net operating loss carryforwards of approximately $329.4 million, which will expire in 2030 through 2032 and foreign tax credit carryforwards of approximately $12.3 million, which will expire in 2019 through 2024. The amount of net operating loss carryforwards expected to be used in 2015 have been included as a current deferred tax asset as of December 31, 2014. The Company has state tax net operating loss carryforwards of approximately $96.0 million, which will expire in 2025 through 2032 and can only be utilized if the Company generates taxable income in particular tax jurisdictions. Based on historical and projected operating results, the Company believed that no valuation allowance was necessary for its deferred tax assets prior to 2013. As a result of the sale of the Downstream segment during the third quarter of 2013, the Company believes that certain state operating loss carryforwards may not be realizable and thus recorded a valuation allowance of $0.9 million as of December 31, 2013. During the third quarter of 2014, the Company recorded an additional $0.1 million related to these state operating losses. In the third quarter of 2013, the Company changed its deferred tax rate to reflect that it will not have future operations in certain states where the Downstream segment operated, resulting in a favorable tax adjustment of $2.8 million. The Company is no longer subject to tax audits by federal, state or local taxing authorities for years prior to 2010. The Company has ongoing examinations by various foreign tax authorities but does not believe that the results of these examinations will have a material adverse effect on the Company’s financial position or results of operations. The following table reconciles the difference between the Company’s income tax provision calculated at the federal statutory rate of 35% and the actual income tax provision (in thousands):

| Commitments and Contingencies | Commitments and Contingencies Vessel Construction In November 2011, the Company announced, and has since expanded, its fifth OSV newbuild program. The program now consists of vessel construction contracts with three domestic shipyards to build four 300 class OSVs, five 310 class OSVs, ten 320 class OSVs and five 310 class MPSVs. As of December 31, 2014, the Company had placed 14 vessels in service under such program. Subsequent to year-end, two additional vessels were placed in service under such program. The eight remaining vessels under this 24-vessel domestic newbuild program are currently expected to be placed in service as follows: five in the remainder of 2015 and three in 2016. Based on current contracts and internal estimates, the aggregate total cost of this program, before construction period interest, is expected to be approximately $1,265.0 million. From the inception of this program through December 31, 2014, the Company has incurred construction costs of approximately $1,032.4 million, or 81.6%, of total expected project costs. Operating Leases The Company is obligated under certain operating leases for office space and shore-base facilities. The Covington facility lease commenced on July 1, 2012 and provides for an initial term expiring in September 2025 with three additional five-year renewal period options. A shore-base facility lease in Port Fourchon commenced on December 20, 2005 and provides for an initial term of seven years with four additional five-year periods upon the terms and conditions contained in the lease agreement. On January 30, 2008, the Company purchased a leasehold interest in a parcel of improved real estate as an adjacent addition to HOS Port, its existing shore-base facility located in Port Fourchon, Louisiana. At December 31, 2014, this latter facility lease had approximately four years remaining on its first renewal option term, with three additional five-year renewal periods. Rent expense related to operating leases was approximately $3.9 million, $3.6 million and $2.6 million for the years ending December 31, 2014, 2013 and 2012, respectively. Future minimum payments under noncancelable leases for years subsequent to 2014 are as follows (in thousands):
Contingencies In the normal course of its business, the Company becomes involved in various claims and legal proceedings in which monetary damages are sought. It is management’s opinion that the Company’s liability, if any, under such claims or proceedings would not materially affect its financial position or results of operations. The Company insures against losses relating to its vessels, pollution and third party liabilities, including claims by employees under Section 33 of the Merchant Marine Act of 1920, or the Jones Act. Third party liabilities and pollution claims that relate to vessel operations are covered by the Company’s entry in a mutual protection and indemnity association, or P&I Club, as well as by marine liability policies in excess of the P&I Club’s coverage. The Company provides reserves for any individual claim deductibles for which the Company remains responsible by using an estimation process that considers Company-specific and industry data, as well as management’s experience, assumptions and consultation with outside counsel. As additional information becomes available, the Company will assess the potential liability related to its pending claims and revise its estimates. Although historically revisions to such estimates have not been material, changes in estimates of the potential liability could materially impact the Company’s results of operations, financial position or cash flows. Vessel charters with Petrobras include limitations regarding fuel consumption. Petrobras has asserted claims against the Company relating to excess fuel consumption. The Company’s exposure for these assessments, net of amounts accrued, is in the range of approximately $0.5 million to $3.0 million. The Company disagrees with a majority of these assessments. While the Company cannot currently estimate the amounts or timing of the resolution of these matters, the Company believes that the outcome will not have a material impact on its liquidity or financial position, but the ultimate resolution could have a material impact on its interim or annual results of operations. During 2013, the Company commenced the process of assigning the in-country vessel management services for its four vessels operating in Brazil from a third party provider to a wholly-owned subsidiary of the Company. As a result, this assignment may be interpreted by local authorities as a new importation of these vessels resulting in an importation assessment ranging from $0.5 million to $3.5 million. The Company disagrees with this interpretation and, as of December 31, 2014, these potential duties have not been assessed or recorded in its financial statements. While the Company cannot estimate the amounts or timing of the resolution of this matter, the Company believes that the outcome will not have a material impact on its liquidity or financial position, but the ultimate resolution could have a material impact on its interim or annual results of operations. During 2012, an Upstream customer, ATP Oil and Gas, Inc., initiated a reorganization proceeding under Chapter 11 of the United States Bankruptcy Code. Pre-petition receivables from ATP were $4.8 million and the Company has recorded $0.9 million in reserves. While the Company believes that the net receivables are collectible, it will continue to monitor the proceedings, which may result in actual collections that may differ from the current estimate. |

| Discontinued Operations | Discontinued Operations On August 29, 2013, the Company closed the sale of substantially all of the assets and business of its Downstream segment's tug and tank barge fleet to Genesis Marine, LLC, an affiliate of Genesis Energy L.P. (NYSE:GEL), for net cash proceeds of approximately of $227.5 million, after deal costs. The sale resulted in a gain of $60.0 million ($38.1 million after-tax or $1.04 per diluted share). Excluded from the sale were three older, lower-horsepower tugs considered to be non-core assets. During the twelve months ended December 31, 2014, the remaining tugs were sold for net cash proceeds of $1.6 million. These sales resulted in a pre-tax gain of approximately $0.9 million ($0.6 million after-tax or $0.02 per diluted share.)

|
|
| Revenue Recognition | Revenue Recognition The Company charters its OSVs and MPSVs to clients under time charters based on a daily rate of hire and recognizes revenue as earned on a daily basis during the contract period of the specific vessel. Deferred revenue represents payments received from customers or billings submitted to customers in advance of providing vessel access through time charters or other contracted arrangements. |
| Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of all highly liquid investments in money market funds, deposits and investments available for current use with an initial maturity of three months or less. |
| Accounts Receivable | Accounts Receivable Accounts receivable consists of trade receivables net of reserves and amounts to be rebilled to customers. |
| Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment is recorded at cost. Depreciation and amortization of equipment and leasehold improvements are computed using the straight-line method based on the estimated useful lives of the related assets. Major modifications and improvements, which extend the useful life of the vessel, are capitalized and amortized over the remaining useful life of the vessel. Gains and losses from retirements or other dispositions are recognized as incurred. Salvage values for new generation marine equipment are estimated to be 25% of the originally recorded cost. |
| Deferred Charges | Deferred Charges The Company’s vessels are required by regulation to be recertified after certain periods of time. The Company defers the drydocking expenditures incurred due to regulatory marine inspections and amortizes the costs on a straight-line basis over the period to be benefited from such expenditures (generally 30 months). Financing charges are amortized over the term of the related debt. Deferred charges also include prepaid lease expenses related to the Company’s shore-base port facility. Such prepaid lease expenses are being amortized on a straight-line basis over the effective remaining term of the lease. |
| Mobilization Costs | Mobilization Costs The Company incurs mobilization costs to transit its vessels to and from certain regions and/or for long-term contracts. These costs, which are typically expensed as incurred, include, but are not limited to, fuel, crew wages, vessel modification and pre-positioning expenses, materials and supplies and importation taxes. The Company incurred mobilization costs of $1.5 million, $2.7 million and $1.4 million during 2014, 2013 and 2012, respectively, associated with the mobilization and pre-positioning of vessels to or from different geographic locations. |
| Income Taxes | Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using currently enacted tax rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The provision for income taxes includes provisions for federal, state and foreign income taxes. Interest and penalties relating to uncertain tax positions are recorded as general and administrative expenses. In addition, the Company provides a valuation allowance for deferred tax assets if it is more likely than not that such items will either expire before the Company is able to realize the benefit or the future deductibility is uncertain. As a result of the sale of the Downstream segment during the third quarter of 2013, the Company believed that certain state operating loss carryforwards would not be realizable and thus recorded a valuation allowance of $0.9 million for the year ended December 31, 2013. During the third quarter of 2014, the Company recorded an additional $0.1 million related to these state operating losses. No valuation allowances were recorded for the year ended December 31, 2012. |
| Use of Estimates | Use of Estimates The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. |
| Legal Liabilities | Legal Liabilities In the ordinary course of business, the Company may become party to lawsuits, administrative proceedings, or governmental investigations. These matters may involve large or unspecified damages or penalties that may be sought from the Company and may require years to resolve. The Company records a liability related to a loss contingency to such legal matters in accrued liabilities if the Company determines the loss to be both probable and estimable. The liability is recorded for an amount that is management’s best estimate of the loss, or when a best estimate cannot be made, the minimum loss amount of a range of possible outcomes. Significant judgment is required in estimating such liabilities, the results of which can vary significantly from the actual outcomes of lawsuits, administrative proceedings or governmental investigations. |
| Concentration of Credit Risk | Concentration of Credit Risk Customers are primarily major and independent, domestic and international, oil and oil service companies, as well as national oil companies and the U.S. military. The Company’s customers are granted credit on a short-term basis and related credit risks are considered minimal. The Company usually does not require collateral. The Company provides an estimate for uncollectible accounts based primarily on management’s judgment using the relative age of customer balances, historical losses, current economic conditions and individual evaluations of each customer to make adjustments to the allowance for doubtful accounts. |
| Impairment of Long-Lived Assets | Impairment of Long-Lived Assets When events or circumstances indicate that the carrying amount of long-lived assets to be held and used or intangible assets might not be recoverable, the expected future undiscounted cash flows from the assets are estimated and compared with the carrying amount of the assets. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the assets, an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the assets with their carrying amounts. Fair value is determined based on discounted cash flow or appraised values, as appropriate. No triggering events occurred in 2014, 2013 or 2012 and the Company did not record any impairment losses related to its long-lived assets during these periods. |
