NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation

The accompanying unaudited consolidated financial statements do not include certain information and footnote disclosures required by United States generally accepted accounting principles, or GAAP. The interim financial statements and notes are presented as permitted by instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments necessary for a fair presentation of the interim financial statements have been included and consist only of normal recurring items. The unaudited quarterly financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K of Hornbeck Offshore Services, Inc. (together with its subsidiaries, the “Company”) for the year ended December 31, 2014. The results of operations for the six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.

The consolidated balance sheet at December 31, 2014 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements.

2. Recent Accounting Pronouncements

On April 7, 2015, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update (ASU) No. 2015-03, "Interest - Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs" (Subtopic 835-30). The amendments in ASU No. 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU No. 2015-03. Therefore, the amortization of such costs will continue to be calculated using the interest method and be reported as interest expense. ASU No. 2015-03 requires retrospective application and will be effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early application is permitted. The Company has approximately $14.6 million of debt issuance costs related to its outstanding senior notes and convertible senior notes that will be subject to this accounting standard. The Company is evaluating the effect of this new standard on its financial statements.

On May 28, 2014, the 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." On July 9, 2015, the FASB voted to defer the effective date of ASU No. 2014-09 by one year to December 15, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. 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 to in exchange for those goods or services. ASU 2014-09 requires retrospective application. The Company is evaluating the effect of this new standard on its financial statements.

3. Earnings Per Share

Basic earnings per common share was calculated by dividing income from continuing operations and income from discontinued operations by the weighted average number of common shares outstanding during the period. Diluted earnings per common share was calculated by dividing income from continuing operations and income from discontinued operations by the weighted average number of common shares outstanding during the year plus the effect of dilutive stock options and restricted stock unit awards. 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. The table below reconciles the Company’s earnings per share (in thousands, except for per share data):



	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014

(1)	On August 29, 2013, the Company closed the sale of its Downstream segment.

(2)

For the three and six months ended June 30, 2015, the Company had 326 and 332 anti-dilutive stock options, respectively. For the three and six months ended June 30, 2014, the Company had no anti-dilutive stock options. Stock options are anti-dilutive when the exercise price of the options is greater than the average market price of the common stock for the period or when the results from operations are a net loss.

(3)

For the three and six months ended June 30, 2015 and 2014, the 2019 convertible senior notes were not dilutive, as the average price of the Company’s stock was less than the effective conversion price of such notes. It is the Company's stated intention to redeem the principal amount of its 2019 convertible senior notes in cash and the Company has used the treasury method for determining potential dilution in the diluted earnings per share computation.


(4)	Dilutive unvested restricted stock units are expected to fluctuate from quarter to quarter depending on the Company’s performance compared to a predetermined set of performance criteria. See Note 6 to these financial statements for further information regarding certain of the Company’s restricted stock grants.

4. Assets Held for Sale

On February 27, 2015, the Company closed on the sale of three 250EDF class OSVs, the HOS Arrowhead, the HOS Eagleview and the HOS Westwind, which were previously chartered to the U.S. Navy, for cash consideration of $114.0 million. The sale resulted in a pre-tax gain of approximately $33.1 million ($20.7 million after-tax or $0.57 per diluted share). The vessel purchase agreement includes an option for the acquisition of a fourth vessel currently under charter to the U.S. Navy, the HOS Black Powder. This purchase option expires on September 30, 2016. In recognition of the purchase option for the HOS Black Powder, the Company has accounted for this vessel as an asset held for sale. As of December 31, 2014, this vessel and its deferred regulatory drydocking costs were included in the Company's fixed assets and deferred charges in the amounts of $25.9 million and $1.2 million, respectively. Since March 31, 2015, the asset and its deferred regulatory drydocking costs have been classified as assets held for sale. The Company has suspended its depreciation and amortization for the vessel until the purchase option is exercised, which is expected to occur on or before September 30, 2015.

As of the dates indicated, the Company had the following outstanding long-term debt (in thousands):

5.875% senior notes due 2020	$	375,000	$	375,000

	1,078,366		1,073,472
Less current maturities	—		—
	$	1,078,366	$	1,073,472

The table below summarizes the Company's cash interest payments (in thousands):



	Semi-Annual Cash Interest Payment		Payment Dates
5.875% senior notes due 2020	$	11,000	April 1 and October 1
5.000% senior notes due 2021	11,300		March 1 and September 1
1.500% convertible senior notes due 2019	2,300		March 1 and September 1

As of June 30, 2015, there were no amounts drawn under the Company’s $300.0 million revolving credit facility and $0.5 million posted as letters of credit. As of June 30, 2015, the Company was in compliance with all financial covenants required by its revolving credit facility and the full amount of the undrawn borrowing base under the facility was available to the Company for all permissible uses of proceeds, including working capital, if necessary.

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, $1,078.4 million and $972.1 million, respectively, as of June 30, 2015. Given the observability 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

During the three and six months ended June 30, 2015, the Company capitalized approximately $6.1 million and $11.9 million, respectively, of interest costs related to the construction of vessels. During the three and six months ended June 30, 2014, the Company capitalized approximately $9.0 million and $17.7 million, respectively, of interest costs related to the construction of vessels.

6. Incentive Compensation

Stock-Based Incentive Compensation Plan

In June 2015, the Company received stockholder approval to increase the maximum number of shares available under its long-term compensation plan by 750,000. The Company’s stock-based incentive compensation plan now covers a maximum of 4.95 million shares of common stock that allows the Company to grant restricted stock awards, restricted stock unit awards, or collectively restricted stock, stock options, stock appreciation rights and fully-vested common stock to employees and directors. As of June 30, 2015, the Company has granted awards covering 4.0 million shares of common stock under such plan.

Table of Contents

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

During the six months ended June 30, 2015, the Company granted cash-settled phantom restricted stock units, time-based restricted stock units, performance-based restricted stock units and fully-vested common stock as noted in the table below.



	Directors	Executive Officers	Certain Managers
Cash-settled phantom restricted stock units		X	X
Time-based restricted stock units		X
Performance-based restricted stock units		X
Fully-vested common stock	X

The shares to be received under the performance-based restricted stock units are calculated based on the Company’s performance compared to three pre-determined criteria, as defined by the restricted stock agreements governing such awards. The actual number of shares that could be received by the award recipients can range from 0% to 150% of the awards granted depending on the Company’s performance. During the six months ended June 30, 2015, the Company granted 353,940 time-based and performance-based restricted stock units, 42,692 cash-settled phantom restricted stock units and 21,737 shares of fully-vested common stock.

Compensation expense related to 2015 restricted stock unit grants is recognized over the three-year service period. The fair value of the Company’s performance-based restricted stock units, which is the stock price on the date of grant, is applied to the total shares that are expected to fully vest and is amortized over the vesting period, which is generally three years, based on the Company’s internal performance measured against the pre-determined criteria, as applicable. The compensation expense related to time-based restricted stock units and cash-settled phantom restricted stock units are 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 and classified as a liability, due to the settlement of these awards in cash. In addition to the restricted stock units granted in 2015, the Company granted performance-based and time-based restricted stock units in 2012, 2013 and 2014. During the six months ended June 30, 2015, the Company issued 258,912 shares, in the aggregate, of stock due to: 1) employees exercising previously vested stock options, 2) vestings of restricted stock units, 3) employee purchases under the Company's Employee Stock Purchase Plan and 4) the issuance of fully-vested common stock.

Stock-based compensation expense charges from previously issued equity grants and the financial impact such grants have on the Company’s operating results are reflected in the table below (in thousands, except for per share data):

7. Commitments and Contingencies

Vessel Construction

The Company's fifth OSV newbuild 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 June 30, 2015, the Company had placed 17 vessels in service under such program. The seven remaining vessels under this 24-vessel domestic newbuild program are currently expected to be placed in service as follows: three in the remainder of 2015 and four in 2016. Based on current contracts and internal estimates, the aggregate cost of this program, excluding construction period interest, is expected to be approximately $1,265.0 million, of which $68.4 million and $54.9 million are expected to be incurred in the remainder of 2015 and fiscal 2016, respectively. From the inception of this program through June 30, 2015, the Company had incurred $1,141.7 million, or 90.3%, of total expected project costs.

Contingencies

In the normal course of its business, the Company becomes involved in various claims and legal proceedings in which monetary damages are sought. 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 revisions to such estimates historically 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 is in the range of approximately $0.5 million to $3.0 million. The Company disagrees with these assessments. During the second quarter of 2015, the Brazilian court ruled in the Company's favor related to these claims. Subsequent to this ruling, Petrobras appealed this decision to a higher court. 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. As of June 30, 2015, 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 materially from the current estimate.

This discussion contains forward-looking statements that reflect our current views with respect to future events and financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements. See “Forward Looking Statements” for additional discussion regarding risks associated with forward-looking statements. In this Quarterly Report on Form 10-Q, “company,” “we,” “us,” “our” or like terms refer to Hornbeck Offshore Services, Inc. and its subsidiaries, except as otherwise indicated. Please refer to Item 5—Other Information for a glossary of terms used throughout this Quarterly Report on Form 10-Q.

In this Quarterly Report on Form 10-Q, we rely on and refer to information regarding our industry from the BOEM, EIA and IHS-Petrodata, Inc. These organizations are not affiliated with us and are not aware of and have not consented to being named in this Quarterly Report on Form 10-Q. We believe this information is reliable. In addition, in many cases we have made statements in this Quarterly Report on Form 10-Q regarding our industry and our position in the industry based on our experience in the industry and our own evaluation of market conditions.

General

During the latter half of 2014 and first half of 2015, oil prices have fallen precipitously from a prevailing price during most of 2014 of over $90 per barrel to a trading range of $45 to $65 per barrel. The drop in oil price appears to be due to surplus oil, driven in part by a significant rise in U.S. shale oil production as well as other previously unavailable sources of supply. In addition, economic weakness in many regions of the world, notably Europe and China, has reduced the previously expected oil consumption growth rate. As a result of the reduction in oil prices, oil companies have significantly reduced their capital spending budgets for 2015. Several major and independent oil companies with deepwater operations have announced capital spending reductions. We believe that the long-term nature of deepwater projects may insulate them, somewhat, from a short-term fall in oil prices. We continue to experience requests by our deepwater customers for price reductions in order to help mitigate the impact that lower commodity prices are having and will continue to have on oil company operating results and cashflows. In addition, sustained low commodity prices may cause projects not fully authorized to be delayed or canceled altogether, which could be manifested in less activity later, even if oil prices recover. We cannot predict whether, and to what extent, or when oil prices will improve. Many of our operations are in support of deepwater projects that are in their final stages or of projects that do not involve deepwater and are more susceptible to immediate wind-down. In addition, shelf drilling activity in the GoM has declined substantially. The lack of a shelf market has impacted us in two ways. First, our low-spec DP-1 vessels in the GoM principally support shelf activities. Second, in prior periods of market over capacity, high-spec equipment has been able to displace low-spec equipment working on the shelf. However, that alternative market for our larger vessels has deteriorated considerably.

The rapid decline in global oil prices has created significant uncertainty in the industry for all of our core markets for the remainder of 2015, which we expect to continue throughout 2016. In the GoM, aggressive cost cutting measures employed by our customers and the increased supply of high-spec OSVs have placed pressure on dayrates across the entire fleet. We expect 33 high-spec OSVs to deliver into the domestic market during 2015, including six of our own. During the second quarter of 2015, there was an average of roughly 47 floating rigs available in the GoM, while an average of 37 were working. As of July 29, 2015, there were 51 rigs available and 41 were working. However, eight floating rigs have contracts that will expire during the remainder of 2015 and two additional rigs are scheduled to leave the region. We do not know whether the remaining rigs will receive contract renewals for operations in the GoM. However, we expect two new rigs to

Table of Contents

arrive in the GoM during 2015, only one of which is contracted. We have recently observed that, following arrival in the GoM, it can take several months for a rig to commence work and, therefore, we do not know the timing of when operations of newly arrived rigs will begin. Given these market conditions, we anticipate our average dayrates and utilization levels to be adversely affected compared to our 2013 and 2014 results.

In recognition of these weak market conditions, we cold-stacked five OSVs during the fourth quarter of 2014 and we have cold-stacked an additional 13 vessels thus far in 2015. By stacking vessels, we expect to significantly reduce our cash outlays, however, we will also have fewer revenue-producing units in service that can potentially contribute to our results. We may choose to stack additional vessels if market conditions deteriorate further.

In Mexico, while the energy reform continues to progress, questions remain on the timing of the incremental activity expected in the deepwater GoM given the current oil price environment. Pemex budget reductions have resulted in contract cancellations and slower than expected growth in the market for our vessels in Mexico. We have noticed that Pemex is reviewing its vessel needs and, in certain circumstances, is not exercising options for vessels that are currently operating in its chartered fleet. Nevertheless, we consider Mexico to be a long-term market for our services, especially in light of energy reforms being carried out there. In the recent Round One auction, conducted by the Mexican National Hydrocarbons Commission, for shallow water properties, there were only two blocks awarded for the 14 properties that were included in such auction. This result may have been caused by the uncertainty in prevailing commodity prices. We will continue to explore opportunities to place additional vessels into Mexico to support Pemex in its ongoing shallow water activity.

In Brazil, lower oil prices combined with a significant corruption probe involving Petrobras and certain of its vendors have combined to create substantial uncertainty over the pace at which Petrobras can proceed with previously announced plans. The four vessels we currently have operating under long-term charter for Petrobras will end their initial term in the second half of 2015. Petrobras has advised us of its intent to allow the charters for those vessels to expire given the current oil price environment. Petrobras generally appears to be moving towards an "all Brazilian flag" vessel fleet, which will limit opportunities in Brazil for foreign flag vessels, except where highly specialized.

Our Vessels

All of our current Upstream vessels are qualified under the Jones Act to engage in U.S. coastwise trade, except for eight foreign-flagged new generation OSVs and two foreign-flagged MPSVs. As of June 30, 2015, our 42 active new generation OSVs and six MPSVs were operating in domestic and international areas as noted in the following table:

Critical Accounting Estimates

This Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses our unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q. In many cases, the accounting treatment of a particular transaction is specifically dictated by U.S. GAAP. In other circumstances, we are required to make estimates, judgments and assumptions that we believe are reasonable based on available information. We base our estimates and judgments on historical experience and various other factors that we believe are reasonable based upon the information available. Actual results may differ from these estimates under different assumptions and conditions. Our significant accounting policies are discussed in Note 2 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014.

Results of Operations

The tables below set forth the average dayrates, utilization rates and effective dayrates for our new generation OSVs and the average number and size of vessels owned during the periods indicated. These vessels generate a substantial portion of our revenues and operating profit. Excluded from the OSV information below are the results of operations for our MPSVs, our shore-base facility, and vessel management services. The Company does not provide average or effective dayrates for its MPSVs. MPSV dayrates are impacted by highly variable customer-required cost-of-sales associated with ancillary equipment and services, such as ROVs, accommodation units and cranes, which are typically recovered through higher dayrates charged to the customer. Due to the fact that each of our MPSVs have a workload capacity and significantly higher income-generating potential than each of the Company’s new generation OSVs, the utilization and dayrate levels of our MPSVs can have a very large impact on our results of operations. For this reason, our consolidated operating results, on a period-to-period basis, are disproportionately impacted by the level of dayrates and utilization achieved by our six MPSVs.

(1)	We owned 60 new generation OSVs as of June 30, 2015. Excluded from this data is one stacked conventional OSV that we consider to be a non-core asset. Also excluded from this data are six MPSVs owned and operated by the Company. During the first six months of 2015, we placed in service three 320 class OSVs, the HOS Caledonia, the HOS Crestview and the HOS Carousel.


(2)	In response to weak market conditions, we elected to stack 18 new generation OSVs on various dates during the fourth quarter of 2014 and the first half of 2015. Active new generation OSVs represent vessels that are immediately available for service during each respective period.


(3)	Average utilization rates are average rates based on a 365-day year. Vessels are considered utilized when they are generating revenues.


(4)	Effective utilization rate is based on a denominator comprised only of vessel-days available for service by the active fleet, which excludes the impact of stacked vessel days.


(5)	Average new generation OSV dayrates represent average revenue per day, which includes charter hire, crewing services, and net brokerage revenues, based on the number of days during the period that the OSVs generated revenues.


(6)	Effective dayrate represents the average dayrate multiplied by the utilization rate for the respective period.

Non-GAAP Financial Measures

We disclose and discuss EBITDA as a non-GAAP financial measure in our public releases, including quarterly earnings releases, investor conference calls and other filings with the Securities and Exchange Commission. We define EBITDA as earnings (net income) before interest, income taxes, depreciation and amortization. Our measure of EBITDA may not be comparable to similarly titled measures presented by other companies. Other companies may calculate EBITDA differently than we do, which may limit its usefulness as comparative measure.

We view EBITDA primarily as a liquidity measure and, as such, we believe that the GAAP financial measure most directly comparable to this measure is cash flows provided by operating activities. Because EBITDA is not a measure of financial performance calculated in accordance with GAAP, it should not be considered in isolation or as a substitute for operating income, net income or loss, cash flows provided by operating, investing and financing activities, or other income or cash flow statement data prepared in accordance with GAAP.

EBITDA is widely used by investors and other users of our financial statements as a supplemental financial measure that, when viewed with our GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to gain an understanding of the factors and trends affecting our ability to service debt, pay deferred taxes and fund drydocking charges and other maintenance capital expenditures. We also believe the disclosure of EBITDA helps investors meaningfully evaluate and compare our cash flow generating capacity from quarter to quarter and year to year.

EBITDA is also a financial metric used by management (i) as a supplemental internal measure for planning and forecasting overall expectations and for evaluating actual results against such expectations; (ii) as a significant criteria for annual incentive cash compensation paid to our executive officers and bonuses paid to other shore-based employees; (iii) to compare to the EBITDA of other companies when evaluating potential acquisitions; and (iv) to assess our ability to service existing fixed charges and incur additional indebtedness.

The following table provides the detailed components of EBITDA from continuing operations as we define that term for the three and six months ended June 30, 2015 and 2014, respectively (in thousands):

Net cash flows provided by operating activities	$	73,311		$	24,018		$	134,749		$	60,722

In addition, we also make certain adjustments to EBITDA for loss on early extinguishment of debt, stock-based compensation expense and interest income to compute ratios used in certain financial covenants of our revolving credit facility with various lenders. We believe that these ratios are a material component of certain financial covenants in such credit agreements and failure to comply with the financial covenants could result in the acceleration of indebtedness or the imposition of restrictions on our financial flexibility.

The following table provides certain detailed adjustments to EBITDA, as defined in our revolving credit facility, for the six months ended June 30, 2015 and 2014, respectively (in thousands):

Adjustments to EBITDA for Computation of Financial Ratios Used in Debt Covenants



	Three Months Ended June 30,				Six Months Ended June 30,

Stock-based compensation expense	$	2,802	$	3,685	$	4,774	$	6,316
Interest income	393		283		607		647

Set forth below are the material limitations associated with using EBITDA as a non-GAAP financial measure compared to cash flows provided by operating activities.


•	EBITDA does not reflect the future capital expenditure requirements that may be necessary to replace our existing vessels as a result of normal wear and tear,


•	EBITDA does not reflect the interest, future principal payments and other financing-related charges necessary to service the debt that we have incurred in acquiring and constructing our vessels,


•	EBITDA does not reflect the deferred income taxes that we will eventually have to pay once we are no longer in an overall tax net operating loss carryforward position, as applicable, and


•	EBITDA does not reflect changes in our net working capital position.

Management compensates for the above-described limitations in using EBITDA as a non-GAAP financial measure by only using EBITDA to supplement our GAAP results.

Three Months Ended June 30, 2015 Compared to Three Months Ended June 30, 2014

Revenues. Revenues for the three months ended June 30, 2015 decreased by $34.7 million, or 20.3%, to $136.4 million compared to the same period in 2014. Our weighted-average active operating fleet for the three months ended June 30, 2015 and 2014 was 48 and 60, respectively. The decrease in revenues was primarily due to soft market conditions in the GoM, which led to our decision to stack 18 OSVs on various dates in the fourth quarter of 2014 and thus far in 2015. For the three months ended June 30, 2015, we had an average of 17.6 vessels stacked compared to none in the prior-year quarter. The decrease in revenue was partially offset by $15.2 million in revenue earned from the full or partial-period contribution of ten vessels that were placed in service since March 2014 under our fifth OSV newbuild program. Average new generation OSV dayrates were $28,178 for the second quarter of 2015 compared to $27,565 for the same period in 2014. Our new generation OSV utilization was 56.2% for the second quarter of 2015 compared to 85.7% for the same period in 2014. Excluding stacked vessel days, our new generation OSV effective utilization was 79.9% and 85.7% for the same periods, respectively. This decrease in utilization is primarily due to soft market conditions for high-spec OSVs operating in the GoM and the incremental vessels that were stacked. Domestic revenues decreased $42.3 million from the year-ago quarter primarily due to lower dayrates earned by vessels operating in our fleet during the three months ended June 30, 2015 and 2014, respectively, and the stacking of vessels in late 2014 and early 2015. Foreign revenues increased by $7.7 million, or 21.9%, as a result of the full or partial period contribution of ten OSVs and one MPSV that relocated to foreign regions since March 2014. Foreign revenues for the second quarter of 2015 comprised 31.3% of our total revenues compared to 20.5% for the year-ago quarter.

Operating Expenses. Operating expenses were $57.5 million, a decrease of $13.9 million, or 19.4%, for the three months ended June 30, 2015 compared to $71.4 million for the same period in 2014. The decrease in operating expenses was primarily due to vessels that we idled or stacked since late 2014, which resulted in a substantial reduction in mariner headcount. This decrease was partially offset by $9.1 million of operating costs related to the full or partial-period contribution from vessels added to our fleet since March 2014. Aggregate cash operating expenses for our vessels are projected to be in the approximate annual range of

Table of Contents

$238.0 million to $248.0 million for the year ending December 31, 2015. The cash operating expense estimate is exclusive of any additional repositioning expenses we may incur in connection with the potential relocation of more of our current spot vessels into international markets or back to the GoM or any customer-required cost-of-sales related to future contract fixtures that are typically recovered through higher dayrates.

Depreciation and Amortization. Depreciation and amortization was $1.1 million, or 3.8%, lower for the three months ended June 30, 2015 compared to the same period in 2014. Depreciation increased by $2.6 million primarily due to the contribution of ten vessels placed in service on various dates since March 2014. The depreciation increase was more than offset by a decrease in amortization expense of $3.6 million, which was primarily due to four vessels sold or classified as held for sale and the deferral of planned drydockings for stacked vessels. Depreciation and amortization expense is expected to continue to increase from current levels as the vessels under our current newbuild program are placed in service and when any newly constructed vessels undergo their initial 30-month and 60-month recertifications.

General and Administrative Expense. General and administrative, or G&A, expenses of $13.1 million, or 9.6% of revenues, decreased by $2.4 million during the three months ended June 30, 2015 compared to the same period in 2014. This decrease in G&A expenses was primarily attributable to the valuation of our stock-based compensation expense, which was driven lower by the recent decline in our stock price, lower shoreside personnel expense and, to a lesser extent, a reduction in bad debt reserves. Our G&A expenses are expected to be in the approximate annual range of $50.0 million to $53.0 million for the year ending December 31, 2015. For future periods, we expect to remain within our historical range of G&A-to-revenue margins, as well as those of our domestic public OSV peer group.

Operating Income. Operating income decreased by $17.4 million, or 30.7%, to $39.4 million during the three months ended June 30, 2015 compared to the same period in 2014 for the reasons discussed above. Operating income as a percentage of revenues was 28.8% for the three months ended June 30, 2015 compared to 33.2% for the same period in 2014.

Interest Expense. Interest expense increased $2.9 million during the three months ended June 30, 2015 compared to the same period in 2014, primarily due to capitalizing a lower percentage of interest compared to the same period in 2014. During the second quarter of 2015, we capitalized interest of $6.1 million, or roughly 38.1% of our total interest costs, compared to capitalized interest of $9.0 million, or roughly 56.3% of our total interest costs, for the same period in 2014.

Interest Income. Interest income was $0.4 million during the three months ended June 30, 2015, which was $0.1 million higher compared to the same period in 2014. Our average cash balance decreased to $259.4 million for the three months ended June 30, 2015 compared to $307.9 million for the same period in 2014. The average interest rate earned on our invested cash balances was 0.5% and 0.4% during the three months ended June 30, 2015 and 2014, respectively. The decrease in average cash balance was primarily due to cash outflows associated with our fifth OSV newbuild program in 2014 and 2015, partially offset by cash inflows from the sale of three vessels to the U.S. Navy in February 2015.

Income Tax Expense. Our effective tax rate was 36.6% and 37.6% for the three months ended June 30, 2015 and 2014, respectively. During the second quarter of 2015, our income tax expense primarily consisted of deferred taxes. Our income tax rate differs from the federal statutory rate primarily due to expected state tax liabilities and items not deductible for federal income tax purposes.

Income from Continuing Operations. Income from continuing operations decreased by $12.0 million to $19.2 million for the three months ended June 30, 2015. This decrease in income from continuing operations for the second quarter of 2015 was primarily due to soft market conditions in the GoM and was partially offset by the full or partial-period contribution of ten vessels placed in service under our fifth OSV newbuild program since March 2014, as well as a decrease in operating, amortization and G&A expenses discussed above.

Six Months Ended June 30, 2015 Compared to Six Months Ended June 30, 2014

Revenues. Revenues for the six months ended June 30, 2015 decreased by $36.6 million, or 11.9%, to $271.1 million compared to the same period in 2014. Our weighted-average active operating fleet for the six months ended June 30, 2015 and 2014 was 52 and 59 vessels, respectively. The decrease in revenues was primarily due to soft market conditions in the GoM, which led to our decision to stack 18 OSVs on various dates in the fourth quarter of 2014 and thus far in 2015. For the six months ended June 30, 2015, we had an average of 13.5 vessels stacked compared to none in the prior-year period. This decrease in revenue was partially offset by $37.3 million in revenue earned from the full or partial-period contribution of 13 vessels that were placed in service under our fifth OSV newbuild program since December 2013. Average new generation OSV dayrates were $27,381 for the first six months of 2015 compared to $26,958 for the same period in 2014, an increase of $423, or 1.6%. Our new generation OSV utilization was 60.5% for the first six months of 2015 compared to 80.6% for the same period in 2014. This decrease in utilization is primarily due to soft market conditions for high-spec OSVs operating in the GoM and the incremental vessels that were stacked during the current-year period. Our high-spec OSVs incurred 130 days of aggregate downtime for regulatory drydockings and were stacked for an aggregate of 1,139 days during the first six months of 2015. Excluding stacked vessel days, our new generation OSV effective utilization was 78.1% and 80.6% for the same periods, respectively. Domestic revenues decreased $66.4 million from the year-ago period primarily due to lower dayrates earned by vessels operating in our fleet during the six months ended June 30, 2015 and June 30, 2014, respectively, and the stacking of vessels in late 2014 and early 2015. Foreign revenues increased $29.8 million primarily due to the full or partial-period contribution of ten OSVs and one MPSV that relocated to foreign regions since December 2013. Foreign revenues for the first six months of 2015 comprised 31.1% of our total revenues compared to 17.7% for the year-ago period.

Operating Expenses. Operating expenses were $119.0 million, a decrease of $21.0 million, or 15.0%, for the six months ended June 30, 2015 compared to $140.0 million for the same period in 2014. Operating expenses were driven lower by vessels that were removed from our active fleet count since late 2014, which resulted in a substantial reduction in mariner headcount. This decrease was partially offset by $21.2 million of operating costs related to the full or partial-period contribution from vessels added to our fleet since

Table of Contents

December 2013. Aggregate cash operating expenses for our vessels are projected to be in the approximate annual range of $238.0 million to $248.0 million for the year ending December 31, 2015. The cash operating expense estimate above is exclusive of any additional repositioning expenses we may incur in connection with the potential relocation of more of our current spot vessels into international markets or back to the GoM from international markets, and any customer-required cost-of-sales related to future contract fixtures that are typically recovered through higher dayrates.

Depreciation and Amortization. Depreciation and amortization was $2.9 million, or 5.2%, lower for the six months ended June 30, 2015 compared to the same period in 2014. Depreciation increased by $6.4 million primarily due to the contribution of 13 vessels that were placed in service on various dates since December 2013. The depreciation increase was more than offset by a decrease in amortization expense of $9.3 million, which was largely due to $5.0 million of incremental amortization recorded for the accelerated regulatory drydocking of vessels during the first six months of 2014. Depreciation and amortization expense is expected to continue to increase from current levels as the vessels under our current newbuild program are placed in service and when any newly constructed vessels undergo their initial 30-month and 60-month recertifications.

General and Administrative Expense. G&A expenses of $25.0 million, or 9.2% of revenues, was $4.2 million lower during the six months ended June 30, 2015 compared to the same period in 2014. The decrease in G&A expenses was primarily due to the cancellation of performance-based RSUs that did not achieve their performance vesting criteria, lower shoreside compensation expense and a reduction in bad debt reserves.

Gain on Sale of Assets. During the first six months of 2015, we completed the sale of three 250EDF class OSVs, the HOS Arrowhead, the HOS Eagleview and the HOS Westwind, to the U.S. Navy for cash consideration of $114.0 million. The sale resulted in a pre-tax gain of approximately $33.1 million ($20.7 million after-tax or $0.57 per diluted share). There was no gain or loss on sale of assets in the same period in 2014.

Operating Income. Operating income increased by $24.5 million, or 29.9%, to $106.3 million during the six months ended June 30, 2015 compared to the same period in 2014 for the reasons discussed above. Operating income as a percentage of revenues was 39.2% for the six months ended June 30, 2015 compared to 26.6% for the same period in 2014. Excluding the gain on sale of assets, our operating income for the first half of 2015 would have been $73.2 million, or 27.0% of revenues.

Interest Expense. Interest expense increased $5.9 million during the six months ended June 30, 2015 compared to the same period in 2014, primarily due to capitalizing a lower percentage of interest compared to the prior-year period. During the six months ended June 30, 2015, we recorded $11.9 million of capitalized construction period interest, or roughly 37.1% of our total interest costs, compared to having capitalized $17.7 million, or roughly 55.5% of our total interest costs, for the year-ago period.

Interest Income. Interest income was $0.6 million during the six months ended June 30, 2015 and June 30, 2014, respectively. Our average cash balance decreased to $252.7 million for the six months ended June 30, 2015 compared to $354.9 million for the same period in 2014. The average interest rate earned on our invested cash balances was 0.4% during the six months ended June 30, 2015 and 2014, respectively. The decrease in average cash balance was primarily due to cash outflows associated with our fifth OSV newbuild program in 2014 and 2015, partially offset by cash inflows from the sale of three vessels to the U.S. Navy in February 2015.

Income Tax Expense. Our effective tax rate was 37.1% and 37.5% for the six months ended June 30, 2015 and 2014, respectively. During the six months ended June 30, 2015, our income tax expense primarily consisted of deferred taxes. Our income tax rate differs from the federal statutory rate primarily due to expected state tax liabilities and items not deductible for federal income tax purposes.

Income from Continuing Operations. Operating performance increased by $12.5 million for reported income from continuing operations of $55.1 million for the six months ended June 30, 2015 compared to the same period during 2014. Excluding the gain on sale of assets, income from continuing operations would have been $34.4 million for the six months ended June 30, 2015 compared to $42.6 million for the same

Table of Contents

period in 2014. This decrease in income from continuing operations for the six months ended June 30, 2015 was primarily due to lower revenues due to soft market conditions discussed above that were partially offset by the gain on the sale of three vessels to the U.S. Navy in February 2015.

Liquidity and Capital Resources

Our capital requirements have historically been financed with cash flows from operations, proceeds from issuances of our debt and common equity securities, borrowings under our credit facilities and cash received from the sale of assets. We require capital to fund on-going operations, remaining obligations under our expanded fifth OSV newbuild program, vessel recertifications, discretionary capital expenditures and debt service and may require capital to fund potential future vessel construction, retrofit or conversion projects, acquisitions or stock repurchases. The nature of our capital requirements and the types of our financing sources are not expected to change significantly for the remainder of 2015.

We have reviewed all of our debt agreements, as well as our liquidity position and projected future cash needs. Despite volatility in commodity markets, we remain confident in our current financial position, the strength of our balance sheet and the short- and long-term viability of our business model. To date, our liquidity has been impacted by such volatility through lower than normal cash flow from operations. However, including cash on-hand, we expect to generate sufficient cash flow from operations to cover all of our growth capital expenditures for the remaining seven HOSMAX vessels under construction, commercial-related capital expenditures, and all of our annually recurring cash debt service, maintenance capital expenditures and cash income taxes through the completion of the newbuild program, as well as discretionary share repurchases from time to time, without ever having to use our currently undrawn revolving credit facility. We have three tranches of funded unsecured debt outstanding that mature in fiscal years 2019, 2020 and 2021, respectively.

As of June 30, 2015, we had total cash and cash equivalents of $263.4 million and a $300 million revolving credit facility, expandable up to $500 million, which is undrawn as of June 30, 2015. We also expect to receive an additional $38.0 million in cash proceeds from the anticipated sale of the fourth 250EDF class OSV to the U.S. Navy during the third quarter of 2015.

On February 6, 2015, we amended and extended the maturity of our existing revolving credit facility to February 2020, provided that, if the 2019 convertible senior notes remain outstanding on March 1, 2019, the Company is required to maintain a specified minimum liquidity level until after the redemption or refinancing of the convertible senior notes, which mature on September 1, 2019. As of June 30, 2015, we had posted letters of credit for $0.5 million and had $299.5 million of credit available under our revolving credit facility. The full undrawn credit amount of such facility is available for all uses of proceeds, including working capital, if necessary. However, the primary intended use of the facility is the potential future construction or acquisition of assets that generate additional EBITDA.

On October 28, 2014, our Board of Directors authorized us to repurchase up to $150 million in shares of our common stock from time to time, $25 million of which was used to buy-back 891,396 shares during the fourth quarter of 2014. There were no such repurchases during the six months ended June 30, 2015. Any future repurchases under this program will be funded from our cash on-hand, cash flow from operations and/or cash proceeds from the divestiture of non-core assets.

Although we expect to continue generating positive working capital through our operations, events beyond our control, such as a further significant decline in commodity prices, renewed regulatory-driven delays in the issuance of drilling plans and permits in the GoM, further declines in expenditures for exploration, development and production activity, any extended reduction in domestic consumption of refined petroleum products and other reasons discussed under the “Forward Looking Statements” on page ii and the Risk Factors stated in Item 1A of our Annual Report on Form 10-K, may affect our financial condition, results of operations or cash flows. Should such need for additional financing arise, we may not be able to access the capital markets on attractive terms at that time or otherwise obtain sufficient capital to meet our maturing debt obligations or finance growth opportunities that may arise. We will continue to closely monitor our liquidity position, as well as the state of the global capital and credit markets.

Cash Flows

Operating Activities. We rely primarily on cash flows from operations to provide working capital for current and future operations. Cash flows from operating activities were $134.7 million for the six months ended June 30, 2015 and $60.7 million for the same period in 2014. Operating cash flows for the first six months

of 2015 were favorably impacted by an increase in customer collections of outstanding accounts receivable balances combined with lower cash outflows for regulatory drydocking expenses compared to the year-ago period. Operating cash flows for the first six months of 2014 included $29.6 million of costs related to regulatory recertifications for our vessels.

Investing Activities. Net cash used in investing activities was $56.2 million for the six months ended June 30, 2015 compared to $240.4 million for the same period in 2014. Cash used during the first six months of 2015 consisted of construction costs incurred for our fifth OSV newbuild program partially offset by proceeds from the February 2015 sale of three 250EDF class OSVs to the U.S. Navy. Cash used in 2014 primarily consisted of construction costs incurred for our fifth OSV newbuild program.

Financing Activities. Net cash used in financing activities was nominal for the six months ended June 30, 2015 compared to cash provided by financing activities of $2.5 million for the same period in 2014. Net cash used in financing activities for the six months ended June 30, 2015 primarily resulted from deferred financing costs related to the amendment and extension of our existing $300 million revolving credit facility offset by net proceeds from common shares issued pursuant to our employee stock-based incentive compensation plans. Net cash provided by financing activities for the six months ended June 30, 2014 primarily resulted from net proceeds from common shares issued pursuant to our employee stock-based incentive compensation plan.

Contractual Obligations

Debt

As of June 30, 2015, the Company had the following outstanding long-term debt (in thousands, except effective interest rate):



	Total Debt		Effective Interest Rate		Semi-Annual Cash Interest Payment		Payment Dates
5.875% senior notes due 2020 (1)	$	375,000	6.08	%	$	11,000	April 1 and October 1
5.000% senior notes due 2021 (1)	450,000		5.21	%	11,300		March 1 and September 1
1.500% convertible senior notes due 2019, net of original issue discount of $46,634	253,366		6.23	%	2,300		March 1 and September 1
	$	1,078,366


(1)	The senior notes do not require any payments of principal prior to their stated maturity dates, but pursuant to the indentures under which the 2020 and 2021 senior notes were issued, we would be required to make offers to purchase such senior notes upon the occurrence of specified events, such as certain asset sales or a change in control.

On February 6, 2015, we amended and extended our revolving credit facility to extend the maturity date, modify covenants and reduce the collateral coverage of such facility. The $300.0 million revolving credit facility remains undrawn as of July 29, 2015. With the revolving credit facility, we have the option of borrowing at a variable rate of interest equal to (i) London Interbank Offered Rate, or LIBOR, plus a margin of 2.0% to 3.0% or (ii) the greatest of the Prime Rate, the Federal Funds Effective Rate plus 1/2 of 1% or LIBOR, plus 1.0%; plus in each case an applicable margin. The applicable margin for each base rate is determined by a pricing grid, which is based on a new total debt-to-capitalization ratio, as defined in the credit agreement governing the revolving credit facility, as amended. The applicable LIBOR margin for the amended revolving credit facility ranges from 200 to 300 basis points. Unused commitment fees are payable quarterly at the annual rate of 37.5 to 50.0 basis points of the unused portion of the borrowing base of the new revolving credit facility, based on the defined total debt-to-capitalization ratio. For additional information with respect to our revolving credit

facility, our 2020 senior notes, our 2021 senior notes and our 2019 convertible senior notes, please refer to Note 5 of our consolidated financial statements included herein.

The credit agreement governing the revolving credit facility and the indentures governing our 2020 and 2021 senior notes impose certain operating and financial restrictions on us. Such restrictions affect, and in many cases limit or prohibit, among other things, our ability to incur additional indebtedness, make capital expenditures, redeem equity, create liens, sell assets and make dividend or other restricted payments. Based on our financial ratios for the six months ended June 30, 2015, the full amount of the undrawn borrowing base under our revolving credit facility is available to us for all uses of proceeds, including working capital, if necessary. For the six months ended June 30, 2015, we were in compliance with all of our debt covenants. We continuously review our debt covenants and report to our lenders our compliance with financial ratios on a quarterly basis. We also consider such covenants in evaluating transactions that will have an effect on our financial ratios.

Capital Expenditures and Related Commitments

The following table sets forth the amounts incurred for our fifth OSV newbuild program, before construction period interest, during the three and six months ended June 30, 2015 and since such program’s inception, respectively, as well as the estimated total project costs for our current expansion program (in millions):



	Three Months Ended June 30, 2015		Six Months Ended June 30, 2015		Incurred Since Inception		Estimated Program Totals (1)		Projected Delivery Dates (1)
Growth Capital Expenditures:
OSV newbuild program #5 (2)	$	61.5	$	109.3	$	1,141.7	$	1,265.0	2Q2013-4Q2016

(1)

Estimated Program Totals and Projected Delivery Dates are based on internal estimates and are subject to change due to delays and possible cost overruns inherent in any large construction project, including, without limitation, shortages of equipment, lack of shipyard availability, unforeseen engineering problems, work stoppages, weather interference, unanticipated cost increases, the inability to obtain necessary certifications and approvals and shortages of materials, component equipment or skilled labor. All of the above historical and budgeted capital expenditure project amounts for our newbuild program represent estimated cash outlays and do not include any allocation of capitalized construction period interest. Projected delivery dates correspond to the first and last vessels that are contracted with shipyards for construction and delivery under our currently active program, respectively.

(2)

Our fifth OSV newbuild 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 June 30, 2015, we had placed 17 vessels in service under such program. The remaining seven vessels under this 24-vessel domestic newbuild program are currently expected to be placed in service as follows: three during the remainder of 2015 and four during 2016.

(1)	Deferred drydocking charges for 2015 include the projected recertification costs for seven OSVs.


(2)	Other vessel capital improvements include costs for discretionary vessel enhancements, which are typically incurred during a planned drydocking event to meet customer specifications.


(3)	Commercial-related vessel improvements include items, such as the addition of cranes, ROVs, helidecks, living quarters and other specialized vessel equipment; the modification of vessel capacities or capabilities, such as DP upgrades and mid-body extensions, which costs are typically included in and offset, in whole or in part, by higher dayrates charged to customers.


(4)	Non-vessel capital expenditures are primarily related to information technology and shoreside support initiatives.

Forward Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking statements,” as contemplated by the Private Securities Litigation Reform Act of 1995, in which the Company discusses factors it believes may affect its performance in the future. Forward-looking statements are all statements other than historical facts, such as statements regarding assumptions, expectations, beliefs and projections about future events or conditions. You can generally identify forward-looking statements by the appearance in such a statement of words like “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “remain,” “should,” “will” or other comparable words or the negative of such words. The accuracy of the Company’s assumptions, expectations, beliefs and projections depends on events or conditions that change over time and are thus susceptible to change based on actual experience, new developments and known and unknown risks. The Company gives no assurance that the forward-looking statements will prove to be correct and does not undertake any duty to update them. The Company’s actual future results might differ from the forward-looking statements made in this Quarterly Report on Form 10-Q for a variety of reasons, including significant and sustained or additional declines in oil and natural gas prices; a sustained weakening of demand for the Company’s services; unplanned customer suspensions, cancellations, rate reductions or non-renewals of vessel charters, management contracts or failures to finalize commitments to charter or manage vessels; further reductions in capital spending budgets by customers; the inability to accurately predict vessel utilization levels and dayrates; fewer than anticipated deepwater and ultra-deepwater drilling units operating in the GoM or other regions where the Company operates; the effect of inconsistency by the United States government in the pace of issuing drilling permits and plan approvals in the GoM or other drilling regions; the Company’s inability to successfully complete the remainder of its current vessel newbuild program on-time and on-budget, which involves the construction and integration of highly complex vessels and systems; the inability to successfully market the vessels that the Company owns, is constructing, or might acquire; the inability of the Company to complete a sale to the U.S. Navy of one additional vessel or the government's cancellation or non-renewal of the operations and maintenance contracts for vessels; an oil

spill or other significant event in the United States or another offshore drilling region that could have a broad impact on deepwater and other offshore energy exploration and production activities, such as the suspension of activities or significant regulatory responses; the imposition of laws or regulations that result in reduced exploration and production activities or that increase the Company’s operating costs or operating requirements; environmental litigation that impacts customer plans or projects; disputes with customers; bureaucratic, administrative or operating barriers that delay vessels in foreign markets from going on-hire or result in contractual penalties or deductions imposed by foreign customers; industry risks; the impact stemming from the reduction of Petrobras' announced plans for or administrative barriers to exploration and production activities in Brazil; less than expected growth in Mexican offshore activities; age or other restrictions imposed on our vessels by customers; unanticipated difficulty in effectively competing in or operating in international markets; less than anticipated subsea infrastructure and field development demand in the GoM and other markets affecting our MPSVs; the level of fleet additions by the Company and its competitors that could result in vessel over capacity in the markets in which the Company competes; economic and political risks; weather-related risks; the shortage of or the inability to attract and retain qualified personnel, as needed, including vessel personnel for active and newly constructed vessels; any success in unionizing the Company's U.S. fleet personnel; regulatory risks; the repeal or administrative weakening of the Jones Act or changes in the interpretation of the Jones Act related to the U.S. citizenship qualification; drydocking delays and cost overruns and related risks; vessel accidents, pollution incidents or other events resulting in lost revenue, fines, penalties or other expenses that are unrecoverable from insurance policies or other third parties; unexpected litigation and insurance expenses; or fluctuations in foreign currency valuations compared to the U.S. dollar and risks associated with expanded foreign operations, such as non-compliance with or the unanticipated effect of tax laws, customs laws, immigration laws, or other legislation that result in higher than anticipated tax rates or other costs or the inability to repatriate foreign-sourced earnings and profits. In addition, the Company’s future results may be impacted by adverse economic conditions, such as inflation, deflation, or lack of liquidity in the capital markets, that may negatively affect it or parties with whom it does business resulting in their non-payment or inability to perform obligations owed to the Company, such as the failure of customers to fulfill their contractual obligations or the failure by individual banks to provide funding under the Company’s credit agreement, if required. Further, the Company can give no assurance regarding when and to what extent it will effect share repurchases. Should one or more of the foregoing risks or uncertainties materialize in a way that negatively impacts the Company, or should the Company’s underlying assumptions prove incorrect, the Company’s actual results may vary materially from those anticipated in its forward-looking statements, and its business, financial condition and results of operations could be materially and adversely affected. Additional factors that you should consider are set forth in detail in the “Risk Factors” section of the Company's most recent Annual Report on Form 10-K as well as other filings the Company has made and will make with the Securities and Exchange Commission which, after their filing, can be found on the Company’s website, www.hornbeckoffshore.com.
