CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
Various statements contained in or incorporated by reference into this Quarterly Report on Form 10-Q (this "Quarterly Report") are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These forward-looking statements include statements, projections and estimates concerning our operations, performance, business strategy, oil and natural gas reserves, drilling program capital expenditures, liquidity and capital resources, the timing and success of specific projects, outcomes and effects of litigation, claims and disputes, derivative activities and potential financing. Forward-looking statements are generally accompanied by words such as "estimate," "project," "predict," "believe," "expect," "anticipate," "potential," "could," "may," "will," "foresee," "plan," "goal," "should," "intend," "pursue," "target," "continue," "suggest" or the negative thereof or other variations thereof or other words that convey the uncertainty of future events or outcomes. Forward-looking statements are not guarantees of performance. These statements are based on certain assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions and expected future developments as well as other factors we believe are appropriate under the circumstances. Among the factors that significantly impact our business and could impact our business in the future are:
the volatility of, and substantial decline in, oil, natural gas liquids ("NGL") and natural gas prices, which remain at low levels;
revisions to our reserve estimates as a result of changes in commodity prices and uncertainties;
impacts to our financial statements as a result of impairment write-downs;
our ability to discover, estimate, develop and replace oil, NGL and natural gas reserves;
uncertainties about the estimates of our oil, NGL and natural gas reserves;
changes in domestic and global production, supply and demand for oil, NGL and natural gas;
the ongoing instability and uncertainty in the U.S.United States and international financial and consumer markets that could adversely affect the liquidity available to us and our customers and the demand for commodities, including oil, NGL and natural gas;
capital requirements for our operations and projects;
our ability to maintain the borrowing capacity under our Senior Secured Credit Facility (as defined below) or access other means of obtaining capital and liquidity, especially during periods of sustained low commodity prices;
restrictions contained in our debt agreements, including our Senior Secured Credit Facility and the indentures governing our senior unsecured notes, as well as debt that could be incurred in the future;
our ability to generate sufficient cash to service our indebtedness, fund our capital requirements and generate future profits;
the potentially insufficient refining capacity in the U.S.United States Gulf Coast to refine all of the light sweet crude oil being produced in the U.S.,United States, which could result in widening price discounts to world crude prices and potential shut-in of production due to lack of sufficient markets;
regulations that prohibit or restrict our ability to apply hydraulic fracturing to our oil and natural gas wells and to access and dispose of water used in these operations;
legislation or regulations that prohibit or restrict our ability to drill new allocation wells;
our ability to execute our strategies, including but not limited to our hedging strategies;
competition in the oil and natural gas industry;
changes in the regulatory environment and changes in international, legal, political, administrative or economic conditions;
drilling and operating risks, including risks related to hydraulic fracturing activities;
risks related to the geographic concentration of our assets;
the availability and costs of drilling and production equipment, labor and oil and natural gas processing and other services;
the availability of sufficient pipeline and transportation facilities and gathering and processing capacity;

iii


the ability to successfully identify and consummate strategic acquisitions at purchase prices that are accretive to our financial results and to successfully integrate acquired businesses, assets and properties;
our ability to comply with federal, state and local regulatory requirements; and
our ability to recruit and retain the qualified personnel necessary to operate our business.

iii


These forward-looking statements involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. Forward-looking statements should, therefore, be considered in light of various factors, including those set forth under "Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" and elsewhere in this Quarterly Report, under "Part I, Item 1A. Risk Factors" and "Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 (the "2015 Annual Report"), and those set forth from time to time in our other filings with the Securities and Exchange Commission (the "SEC"). These documents are available through our website or through the SEC's Electronic Data Gathering and Analysis Retrieval system at http://www.sec.gov. In light of such risks and uncertainties, we caution you not to place undue reliance on these forward-looking statements. These forward-looking statements speak only as of the date of this Quarterly Report, or if earlier, as of the date they were made. We do not intend to, and disclaim any obligation to, update or revise any forward-looking statements unless required by securities law.

Note 1—Organization
Laredo Petroleum, Inc. ("Laredo"), together with its subsidiaries, Laredo Midstream Services, LLC ("LMS") and Garden City Minerals, LLC ("GCM"), is an independent energy company focused on the acquisition, exploration and development of oil and natural gas properties, and the transportation of oil and natural gas from such properties, primarily in the Permian Basin in West Texas. LMS and GCM (together, the "Guarantors") guarantee all of Laredo's debt instruments. In these notes, the "Company" refers to Laredo, LMS and GCM collectively, unless the context indicates otherwise. All amounts, dollars and percentages presented in these unaudited consolidated financial statements and the related notes are rounded and therefore approximate.
The Company operates in two business segments, which aresegments: (i) exploration and production and (ii) midstream and marketing. The exploration and production segment is engaged in the acquisition, exploration and development of oil and natural gas properties primarily in the Permian Basin in West Texas. The midstream and marketing segment provides Laredo's exploration and production segment and third parties with products and services that need to be delivered by midstream infrastructure, including oil and natural gas gathering services as well as rig fuel, natural gas lift and water delivery and takeaway in and around Laredo's primary production corridors.
Note 2—Basis of presentation and significant accounting policies
a.    Basis of presentation
The accompanying unaudited consolidated financial statements were derived from the historical accounting records of the Company and reflect the historical financial position, results of operations and cash flows for the periods described herein. The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). All material intercompany transactions and account balances have been eliminated in the consolidation of accounts. The Company uses the equity method of accounting to record its net interests when the Company holds 20% to 50% of the voting rights and/or has the ability to exercise significant influence but does not control the entity. Under the equity method, the Company's proportionate share of the investee's net income (loss) is included in the unaudited consolidated statements of operations. See Note 14 for additional discussion of the Company's equity method investment.
The accompanying consolidated financial statements have not been audited by the Company's independent registered public accounting firm, except that the consolidated balance sheet as of December 31, 2015 is derived from audited consolidated financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements reflect all necessary adjustments to present fairly the Company's financial position as of March 31,June 30, 2016, results of operations for the three and six months ended March 31,June 30, 2016 and 2015 and cash flows for the threesix months ended March 31,June 30, 2016 and 2015.
Certain disclosures have been condensed or omitted from these unaudited consolidated financial statements. Accordingly, these unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the 2015 Annual Report.
b.    Use of estimates in the preparation of interim unaudited consolidated financial statements
The preparation of the accompanying unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although management believes these estimates are reasonable, actual results could differ. The interim results reflected in the unaudited consolidated financial statements are not necessarily indicative of the results that may be expected for other interim periods or for the full year.
Significant estimates include, but are not limited to, (i) estimates of the Company's reserves of oil, NGL and natural gas, (ii) future cash flows from oil and natural gas properties, (iii) depletion, depreciation and amortization, (iv) asset retirement obligations, (v) stock-based compensation, (vi) deferred income taxes, (vii) fair value of assets acquired and liabilities assumed in an acquisition and (viii) fair values of derivatives, deferred premiums and performance unit awards. As fair value is a market-based measurement, it is determined based on the assumptions that would be used by market participants. These estimates and assumptions are based on management's best judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. Such estimates and assumptions are adjusted when facts and circumstances dictate. Illiquid credit markets and volatile equity and energy markets have combined to increase the uncertainty inherent in such estimates and assumptions. Management believes its estimates and
Laredo Petroleum, Inc.
Condensed notes to the consolidated financial statements
(Unaudited)

assumptions to be reasonable under the circumstances. As future events and their effects cannot be determined with precision, actual values and results could differ from these estimates. Any changes in estimates resulting from future changes in the economic environment will be reflected in the financial statements in future periods.
c.    Reclassifications
Certain amounts in the accompanying unaudited consolidated financial statements have been reclassified to conform to the 2016 presentation. These reclassifications had no impact to previously reported net loss, stockholders' equity or cash flows.
d.    Accounts receivable
The Company sells produced and purchased oil, NGL and natural gas and purchased oil to various customers and participates with other parties in the development and operation of oil and natural gas properties. The Company's accounts receivable are generally unsecured. Accounts receivable for joint interest billings are recorded as amounts billed to customers less an allowance for doubtful accounts.
Joint interest operations amounts are considered past due after 30 days. The Company determines joint interest operations accounts receivable allowances based on management's assessment of the creditworthiness of the joint interest owners. Additionally, as the operator of the majority of its wells, the Company has the ability to realize some or all of the receivables through netting of anticipated future production revenues. The Company maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses, current receivables aging and existing industry and economic data. The Company reviews its allowance for doubtful accounts quarterly. Past due amounts greater than 90 days and over a specified amount are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is remote.
    
Accounts receivable consisted of the following components for the periods presented:
(in thousands) March 31, 2016 December 31, 2015 June 30, 2016 December 31, 2015

(1)Accounts receivable for joint operations are presented net of an allowance for doubtful accounts of $0.2 million as of both March 31,June 30, 2016 and December 31, 2015.
e.    Derivatives
The Company uses derivatives to reduce exposure to fluctuations in the prices of oil, NGL and natural gas. By removing a significant portion of the price volatility associated with future production, the Company expects to mitigate, but not eliminate, the potential effects of variability in cash flows from operations due to fluctuations in commodity prices. These transactions are in the form of puts, swaps, collars and, in prior periods, basis swaps.
Derivatives are recorded at fair value and are presented on a net basis on the unaudited consolidated balance sheets as assets or liabilities. The Company nets the fair value of derivatives by counterparty where the right of offset exists. The Company determines the fair value of its derivatives by utilizing pricing models for substantially similar instruments. Inputs to the pricing models include publicly available prices and forward price curves generated from a compilation of data gathered from third parties. See Note 9 for discussion regarding the fair value of the Company's derivatives. 
The Company's derivatives were not designated as hedges for accounting purposes for any of the periods presented. Accordingly, the changes in fair value are recognized in the unaudited consolidated statements of operations in the period of change. Gains and losses on derivatives are included in cash flows from operating activities. See Notes 8 and 9 for discussion regarding the Company's derivatives.

For the three months ended March 31,June 30, 2016 and 2015, depletion expense was $9.007.06 per barrel of oil equivalent ("BOE") sold and $16.08$16.19 per BOE sold, respectively. For the six months ended June 30, 2016 and 2015, depletion expense was $8.01 per BOE sold and $16.13 per BOE sold, respectively.
The Company uses the full cost method of accounting for its oil and natural gas properties. Under this method, all acquisition, exploration and development costs, including certain related employee costs, incurred for the purpose of finding oil, NGL and natural gas are capitalized and depleted on a composite unit of production method based on proved oil, NGL and natural gas reserves. Such amounts include the cost of drilling and equipping productive wells, dry hole costs, lease acquisition costs, delay rentals and other costs related to such activities. Costs, including related employee costs, associated with production and general corporate activities are expensed in the period incurred. Sales of oil and natural gas properties, whether or not being depleted currently, are accounted for as adjustments of capitalized costs, with no gain or loss recognized, unless such adjustments would significantly alter the relationship between capitalized costs and proved reserves of oil, NGL and natural gas.
The Company excludes the costs directly associated with acquisition and evaluation of unevaluated properties from the depletion calculation until it is determined whether or not proved reserves can be assigned to the properties. The Company capitalizes a portion of its interest costs on its unevaluated properties. Capitalized interest becomes a part of the cost of the unevaluated properties and is subject to depletion when proved reserves can be assigned to the associated properties. All items classified as unevaluated property are assessed on a quarterly basis for possible impairment or reduction in value. The assessment includes consideration of the following factors, among others: intent to drill, remaining lease term, geological and geophysical evaluations, drilling results and activity, the assignment of evaluated reserves and the economic viability of development if proved reserves are assigned. During any period in which these factors indicate an impairment, the cumulative drilling costs incurred to date for such property and all or a portion of the associated leasehold costs are transferred to the full cost pool and are then subject to depletion.
The full cost ceiling is based principally on the estimated future net revenues from proved oil and natural gas properties discounted at 10%. Per the SEC guidelines, companies are required to use the unweighted arithmetic average first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period before differentials ("Benchmark Prices"). The Benchmark Prices are then adjusted for quality, transportation fees, geographical differentials, marketing bonuses or deductions and other factors affecting the price received at the wellhead ("Realized Prices"). The Realized Prices are utilized to calculate the discounted future net revenues in the full cost ceiling calculation.

In the event the unamortized cost of evaluated oil and natural gas properties being depleted exceeds the full cost ceiling, as defined by the SEC, the excess is charged to expense in the period such excess occurs. Once incurred, a write-down of oil and natural gas properties is not reversible.
The following table presents the Benchmark Prices, Realized Prices and the corresponding non-cash full cost ceiling impairments recorded as of the periods presented:

Full cost ceiling impairment expense is included in the "Impairment expense" line item in the unaudited consolidated statements of operations and in the financial information provided for the Company's exploration and production segment presented in Note 16.
g. Long-lived assets and inventory
Impairment losses are recorded on property and equipment used in operations and other long-lived assets when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying amount. Impairment is measured based on the excess of the carrying amount over the fair value of the asset.
Materials and supplies inventory used in developing oil and natural gas properties and midstream service assets are carried at the lower of cost or market ("LCM") with cost determined using the weighted-average cost method and are included in "Other current assets" and "Other assets, net" on the unaudited consolidated balance sheets. The market price for materials and supplies is determined utilizing a replacement cost approach.approach (Level 2).
Beginning at March 31, 2016, frac pit water inventory used in developing oil and natural gas properties is carried at LCM with cost determined using the weighted-average cost method and is included in "Other current assets" on the unaudited consolidated balance sheets. The market price for frac pit water inventory is determined utilizing a replacement cost approach.
The minimum volume of product in a pipeline system that enables the system to operate is known as line-fill and is generally not available to be withdrawn from the pipeline system until the expiration of the transportation contract. The Company owns oil line-fill in third-party pipelines, which is accounted for at LCM with cost determined using the weighted-average cost method and is included in "Other assets, net" on the unaudited consolidated balance sheets. The LCM adjustment is determined utilizing a quoted market price adjusted for regional price differentials (Level 2).

h.    Debt issuance costs
Debt issuance fees, which are recorded at cost, net of amortization, are amortized over the life of the respective debt agreements utilizing the effective interest and straight-line methods. The Company capitalized $6.4$6.8 million of debt issuance costs during the threesix months ended March 31,June 30, 2015 mainly as a result of the issuance of the March 2023 Notes (as defined below). No debt issuance costs were capitalized in the threesix months ended March 31,June 30, 2016. The Company had total debt issuance costs of $22.8$20.9 million and $23.9 million, net of accumulated amortization of $18.219.2 million and $17.0 million, as of March 31,June 30, 2016 and December 31, 2015, respectively.
NoThe Company wrote-off approximately $0.8 million of debt issuance costs were written off during the threesix months ended March 31,June 30, 2016 or 2015.as a result of changes in the borrowing base and aggregate elected commitment of the Senior Secured Credit Facility, which are included in the unaudited consolidated statements of operations in the "Write-off of debt issuance costs" line item. During the six months ended June 30, 2015, the Company wrote-off approximately $6.6 million of debt issuance costs as a result of the early redemption of the January 2019 Notes (as defined below), which are included in the unaudited consolidated statements of operations in the "Loss on early redemption of debt" line item. Unamortized debt issuance costs related to the Company's senior unsecured notes are presented in "Long-term debt, net" on the Company's unaudited consolidated balance sheets. Unamortized debt issuance costs related to the Senior Secured Credit Facility are presented in "Other assets, net" on the Company's unaudited consolidated balance sheets.

j.    Asset retirement obligations
Asset retirement obligations associated with the retirement of tangible long-lived assets are recognized as a liability in the period in which they are incurred and become determinable. The associated asset retirement costs are part of the carrying amount of the long-lived asset. Subsequently, the asset retirement cost included in the carrying amount of the related long-lived asset is charged to expense through depletion, or for midstream service asset retirement cost through depreciation, of the associated asset. Changes in the liability due to the passage of time are recognized as an increase in the carrying amount of the liability and as corresponding accretion expense.
The fair value of additions to the asset retirement obligation liability is measured using valuation techniques consistent with the income approach, which converts future cash flows into a single discounted amount. Significant inputs to the valuation include: (i) estimated plug and abandonment cost per well based on Company experience, (ii) estimated remaining life per well, (iii) estimated removal and/or remediation costs for midstream service assets, (iv) estimated remaining life of midstream service assets, (v) future inflation factors and (vi) the Company's average credit adjusted risk-free rate. Inherent in the fair value calculation of asset retirement obligations are numerous assumptions and judgments including, in addition to those noted above, the ultimate settlement of these amounts, the ultimate timing of such settlement and changes in legal, regulatory, environmental and political environments. To the extent future revisions to these assumptions impact the fair value of the existing asset retirement obligation liability, a corresponding adjustment will be made to the asset balance.
The Company is obligated by contractual and regulatory requirements to remove certain pipeline and gas gathering assets and perform other remediation of the sites where such pipeline and gas gathering assets are located upon the retirement of those assets. However, the fair value of the asset retirement obligation cannot currently be reasonably estimated because the settlement dates are indeterminate. The Company will record an asset retirement obligation for pipeline and gas gathering assets in the periods in which settlement dates become reasonably determinable.
The following reconciles the Company's asset retirement obligation liability for the periods presented:
(in thousands) Three months ended March 31, 2016 Year ended December 31, 2015 Six months ended June 30, 2016 Year ended December 31, 2015

k.    Fair value measurements
The carrying amounts reported in the unaudited consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable, undistributed revenue and royalties, accrued capital expenditures and other accrued assets and liabilities approximate their fair values. See Note 5.f for fair value disclosures related to the Company's debt obligations. The Company carries its derivatives at fair value. See Note 9 for details regarding the fair value of the Company's derivatives.
l.    Treasury stock
Laredo's employees may elect to have the Company withhold shares of stock to satisfy their tax withholding obligations that arise upon the lapse of restrictions on their stock awards. Such treasury stock is recorded at cost and retired upon acquisition.
m.    Compensation awards
Stock-based compensation expense, net of amounts capitalized, is included in "General and administrative" in the unaudited consolidated statements of operations over the awards' vesting periods and is based on the awards' grant date fair value. The Company utilizes the closing stock price on the grant date, less an expected forfeiture rate, to determine the fair value of service vesting restricted stock awards and a Black-Scholes pricing model to determine the fair values of service vesting restricted stock option awards. The Company utilizes a Monte Carlo simulation prepared by an independent third party to determine the fair values of the performance share awards and, in prior periods, the performance unit awards. The Company capitalizes a portion of stock-based compensation for employees who are directly involved in the acquisition, exploration and development of its oil and gas properties into the full cost pool. Capitalized stock-based compensation is included as an addition to "Oil and natural gas properties" in the unaudited consolidated balance sheets. See Note 6 for further discussion regarding the restricted stock awards, restricted stock option awards, performance share awards and performance unit awards.

The LTIP provides forIn the issuancesecond quarter of 10.0 million shares. On March 30, 2016, shareholders approved an increase in the Company's compensation committee recommended, and the Company's board of directors adopted, subject to stockholder approval, an amendment to the LTIP to, among other things, increase themaximum number of shares of the Company's common stock available for issuanceissuable under the LTIP by 14,350,000from 10,000,000 shares to 24,350,000 shares (the "Amendment"), enabling the continued use of the LTIP for share-based awards. The Company is seeking stockholder approval of the Amendment in connection with its 2016 Annual Meeting of Stockholders on May 25, 2016..
The Company recognizes the fair value of stock-based compensation awards expected to vest over the requisite service period as a charge against earnings, net of amounts capitalized. The Company's stock-based compensation awards are accounted for as equity instruments, and in prior periods, its performance unit awards were accounted for as liability awards. Stock-based compensation is included in "General and administrative" in the unaudited consolidated statements of operations. The Company capitalizes a portion of stock-based compensation for employees who are directly involved in the acquisition, exploration and development of oil and natural gas properties into the full cost pool. Capitalized stock-based compensation is included as an addition to "Oil and natural gas properties" in the unaudited consolidated balance sheets.
a.    Restricted stock awards
All restricted stock awards are treated as issued and outstanding in the accompanying unaudited consolidated financial statements. Per the award agreement terms, if an employee terminates employment prior to the restriction lapse date for reasons other than death or disability, the awarded shares are forfeited and canceled and are no longer considered issued and outstanding. If the employee's termination of employment is by reason of death or disability, all of the holder's restricted stock will automatically vest. RestrictedHistorically, restricted stock awards granted to officers and employees vest in a variety of vesting schedules including (i) 33%, 33% and 34% per year beginning on the first anniversary date of the grant, (ii) 50% in year two and 50% in year three, (iii) fully on the first anniversary of the grant date and (iv) fully on the third anniversary of the grant date. Restricted stock awards granted to non-employee directors vest fully on the first anniversary of the grant date.

The Company utilizes the Black-Scholes option pricing model to determine the fair value of restricted stock option awards and recognizes the associated expense on a straight-line basis over the four-year requisite service period of the awards. Determining the fair value of equity-based awards requires judgment, including estimating the expected term that stock option awards will be outstanding prior to exercise and the associated volatility. As of March 31,June 30, 2016, unrecognized stock-based compensation related to restricted stock option awards expected to vest was $5.4$13.5 million. Such cost is expected to be recognized over a weighted-average period of 2.142.55 years.

The assumptions used to estimate the fair value of the 22,324 restricted stock options granted on April 1, 2016 and the 994,022 restricted stock options granted on May 25, 2016 are as follows:
  April 1, 2016 May 25, 2016
Risk-free interest rate(1)
 1.44% 1.58%

 6.25 years
 6.25 years
Expected volatility(3)
 61.34% 61.94%
Fair value per stock option $4.44
 $9.75
(1)United States Treasury yields as of the grant date were utilized for the risk-free interest rate assumption, correlating the treasury yield terms to the expected life of the option.
(2)As the Company had limited exercise history at the time of valuation relating to terminations and modifications, expected option life assumptions were developed using the simplified method in accordance with GAAP.
(3)The Company utilized its own historical volatility in order to develop the expected volatility.     
In accordance with the LTIP and stock option agreement, the options granted will become exercisable in accordance with the following schedule based upon the number of full years of the optionee's continuous employment or service with the Company, following the date of grant:
Full years of continuous employment Incremental percentage of
option exercisable
 Cumulative percentage of
option exercisable
Less than one % %
One 25% 25%
Two 25% 50%
Three 25% 75%
Four 25% 100%
No shares of common stock may be purchased unless the optionee has remained in continuous employment with the Company for one year from the grant date. Unless terminated sooner, the option will expire if and to the extent it is not exercised within 10 years from the grant date. The unvested portion of a stock option award shall expire upon termination of employment, and the vested portion of a stock option award shall remain exercisable for (i) one year following termination of employment by reason of the holder's death or disability, but not later than the expiration of the option period, or (ii) 90 days following termination of employment for any reason other than the holder's death or disability, and other than the holder's termination of employment for cause. Both the unvested and the vested but unexercised portion of a stock option award shall expire upon the termination of the option holder's employment or service by the Company for cause.

A Monte Carlo simulation prepared by an independent third party was utilized to determine the grant date fair value of these awards. The Company has determined these awards are equity awards and recognizes the associated expense on a straight-line basis over the three-year requisite service period of the awards. These awards will be settled, if at all, in stock at the end of the requisite service period based on the achievement of certain performance criteria.
The 520,8961,742,469 outstanding 2016 Performance Share Awards have a performance period of January 1, 2016 to December 31, 2018, and any shares earned under such awards are expected to be issued in the first quarter of 2019 if the performance criteria are met.

e.    Performance unit awards
The performance unit awards issued to management on February 15, 2013 (the "2013 Performance Unit Awards") and on February 3, 2012 (the "2012 Performance Unit Awards") were subject to a combination of market and service vesting criteria. These awards were accounted for as liability awards as they were settled in cash at the end of the requisite service period based on the achievement of certain performance criteria.
The 44,481 settled 2013 Performance Unit Awards had a performance period of January 1, 2013 to December 31, 2015 and, as their performance criteria were satisfied, they were paid at $143.75 per unit during the first quarter of 2016. The 27,381 settled 2012 Performance Unit Awards had a performance period of January 1, 2012 to December 31, 2014 and, as their performance criteria were satisfied, they were paid at $100.00 per unit during the first quarter of 2015.

Note 7—Income taxes
Income taxes are accounted for under the asset and liability method. 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 and operating losses and tax credit carry-forwards. Under this method, deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income (loss) in the period that includes the enactment date.
The Company evaluates uncertain tax positions for recognition and measurement in the unaudited consolidated financial statements. To recognize a tax position, the Company determines whether it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation, based on the technical merits of the position. A tax position that meets the more-likely-than-not threshold is measured to determine the amount of benefit to be recognized in the unaudited consolidated financial statements. The amount of tax benefit recognized with respect to any tax position is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. The Company hashad no unrecognized tax benefits related to uncertain tax positions in the unaudited consolidated financial statements as of March 31,June 30, 2016 or December 31, 2015.
The Company is subject to federal and state income taxes and the Texas franchise tax. Income tax expensebenefit for the periods presented consisted of the following:

For the three and six months ended March 31,June 30, 2016, the effective tax rate on loss before income taxes was not meaningful due to the valuation allowance recorded. For the three and six months ended March 31,June 30, 2015, the effective tax rate on income before income taxes was not meaningful due to the significant effect of discrete items on a relatively small amount of income.36% and 35%, respectively. The Company's effective tax rate is affected by changes in valuation allowances, recurring permanent differences and by discrete items that may occur in any given year, but are not consistent from year to year.
A valuation allowance is established to reduce deferred tax assets if it is determined that it is more likely than not that the related tax benefit will not be realized. On a quarterly basis, management evaluates the need for and adequacy of valuation allowances based on the expected realizability of the deferred tax assets and adjusts the amount of such allowances, if necessary. During the year ended December 31, 2015 and the threesix months ended March 31,June 30, 2016, in evaluating whether it was more likely than not that the Company's net deferred tax assets were realizedrealizable through future net income, management considered all available positive and negative evidence, including (i) its earnings history, (ii) its ability to recover net operating loss carry-forwards, (iii) the existence of significant proved oil, NGL and natural gas reserves, (iv) its ability to use tax planning
Laredo Petroleum, Inc.
Condensed notes to the consolidated financial statements
(Unaudited)

strategies, (v) its current price protection utilizing oil and natural gas hedges, (vi) its future revenue and operating cost projections and (vii) the current market prices for oil, NGL and natural gas. Based on all the evidence available, during the year ended December 31, 2015, management determined it was more likely than not that the net deferred tax assets were not realizable, and therefore recorded a valuation allowance of $676.0 million. During the threesix months ended March 31,June 30, 2016, an additional valuation allowance of $57.7$83.7 million was recorded.
The impact of significant discrete items is separately recognized in the quarter in which the discrete items occur. The vesting of certain restricted stock awards could result in federal and state income tax expense or benefits related to the difference between the market price of the common stock at the date of vesting and the grant date. The exercise of stock option awards could result in federal and state income tax expense or benefits related to the difference between the fair value of the stock option at the grant date and the intrinsic value of the stock option when exercised. The tax impact resulting from vestings of restricted stock awards and exercise of option awards are discrete items. During the three and six months ended March 31,June 30, 2016 and 2015, certain shares related to restricted stock awards vested at times when the Company's stock price was lower than the fair value of those shares at the time of the grant. As a result, the income tax deduction related to such shares is less than the expense previously recognized for book purposes. During the three and six months ended March 31,June 30, 2016, and 2015, no restrictedcertain stock options were exercised. No stock options were exercised during the three and six months ended June 30, 2015. The income tax deduction related to the intrinsic value of the options was less than the expense previously recognized for book purposes. In accordance with GAAP, such shortfalls reduce additional paid-in capital to the extent windfall tax benefits have been previously recognized. However, the Company has not previously recognized any windfall tax benefits. Therefore, such shortfalls are included in income tax expense.

The Company had federal net operating loss carry-forwards totaling $1.41.5 billion and state of Oklahoma net operating loss carry-forwards totaling $40.941.0 million as of March 31,June 30, 2016. These carry-forwards begin expiring in 2026. Additionally, these carry-forwards include windfall tax deductions from vestings of certain restricted stock awards and stock option exercises that were not recorded in the Company's income tax provision. The amount of windfall tax benefit recognized in additional paid-in capital is limited to the amount of benefit realized currently in income taxes payable. As of March 31,June 30, 2016, the Company had suspended additional paid-in capital credits of $4.5 million related to windfall tax deductions. Upon realization of the net operating loss carry-forwards from such windfall tax deductions, the Company would record a benefit of up to $4.5 million in additional paid-in capital.
The Company's income tax returns for the years 2012 through 2015 remain open and subject to examination by federal tax authorities and/or the tax authorities in Oklahoma and Texas, which are the jurisdictions where the Company has or had operations. Additionally, the statute of limitations for examination of federal net operating loss carry-forwards typically does not begin to run until the year the attribute is utilized in a tax return.

Note 8—Derivatives
a. Derivatives
The Company engages in derivative transactions such as puts, swaps, collars and, in prior periods, basis swaps to hedge price risks due to unfavorable changes in oil and natural gas prices related to its production. As of March 31,June 30, 2016, the Company had 2125 open derivative contracts with financial institutions that extend from AprilJuly 2016 to December 2018. None of these contracts were designated as hedges for accounting purposes. The contracts are recorded at fair value on the unaudited consolidated balance sheets and gains and losses are recognized in current period earnings. Gains and losses on derivatives are reported on the unaudited consolidated statements of operations on the "Gain (loss) on derivatives, net" line item.
Each put transaction has an established floor price. The Company pays its counterparty a premium, which can be deferred until settlement, to enter into the put transaction. When the settlement price is below the floor price, the counterparty pays the Company an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume. When the settlement price is above the floor price, the put option expires.
Each swap transaction has an established fixed price. When the settlement price is below the fixed price, the counterparty pays the Company an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume. When the settlement price is above the fixed price, the Company pays its counterparty an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume.
Each collar transaction has an established price floor and ceiling. When the settlement price is below the price floor established by these collars, the Company receives an amount from its counterparty equal to the difference between the settlement price and the price floor multiplied by the hedged contract volume. When the settlement price is above the price ceiling established by these collars, the Company pays its counterparty an amount equal to the difference between the settlement price and the price ceiling multiplied by the hedged contract volume.
In the prior year, the oil basis swap transactions had an established fixed basis differential. The Company's oil basis swaps' differential was between the West Texas Intermediate-Argus Americas Crude (Midland) ("WTI Midland") index crude
Laredo Petroleum, Inc.
Condensed notes to the consolidated financial statements
(Unaudited)

oil price and the West Texas Intermediate NYMEX ("WTI NYMEX") index crude oil price. When the WTI NYMEX price less the fixed basis differential was greater than the actual WTI Midland price, the difference multiplied by the hedged contract volume was paid to the Company by the counterparty. When the WTI NYMEX price less the fixed basis differential was less than the actual WTI Midland price, the difference multiplied by the hedged contract volume was paid by the Company to the counterparty.

During the threesix months ended March 31,June 30, 2016, the Company successfully completed a hedge restructuring by early terminating the floors of certain derivative contract collars that resulted in a termination amount of $80 million, which was settled in full by applying the proceeds to prepay the premiums on two new derivatives entered into during the restructuring.

(1)Oil derivatives are settled based on the average of the daily settlement prices for the First Nearby Month of the WTI NYMEX Light Sweet Crude Oil Futures Contract for each NYMEX Trading Day during each month.
(2)Natural gas derivatives are settled based on the Inside FERC index price for West Texas Waha for the calculation period.
b. Balance sheet presentation
In accordance with the Company's standard practice, its derivatives are subject to counterparty netting under agreements governing such derivatives. The Company's oil and natural gas derivatives are presented on a net basis as "Derivatives" on the unaudited consolidated balance sheets. See Note 9.a for a summary of the fair value of derivatives on a gross basis.
By using derivatives to hedge exposures to changes in commodity prices, the Company exposes itself to credit risk and market risk. For the Company, market risk is the exposure to changes in the market price of oil and natural gas, which are subject to fluctuations from a variety of factors, including changes in supply and demand. Credit risk is the failure of the
Laredo Petroleum, Inc.
Condensed notes to the consolidated financial statements
(Unaudited)

counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, thereby creating credit risk. The Company's counterparties are participants in the Senior Secured Credit Facility, which is secured by the Company's oil and natural gas reserves; therefore, the Company is not required to post any collateral. The Company does not require collateral from its derivative counterparties. The Company minimizes the credit risk in derivatives by: (i) limiting its exposure to any single counterparty, (ii) entering into derivatives only with counterparties that meet the Company's minimum credit quality standard or have a guarantee from an affiliate that meets the Company's minimum credit quality standard and (iii) monitoring the creditworthiness of the Company's counterparties on an ongoing basis.
Note 9—Fair value measurements
The Company accounts for its oil and natural gas derivatives at fair value. The fair value of derivatives is determined utilizing pricing models for similar instruments. The models use a variety of techniques to arrive at fair value, including quotes and pricing analysis. Inputs to the pricing models include publicly available prices and forward curves generated from a compilation of data gathered from third parties.
The Company has categorized its assets and liabilities measured at fair value, based on the priority of inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).
Assets and liabilities recorded at fair value on the unaudited consolidated balance sheets are categorized based on inputs to the valuation techniques as follows: 
Level 1—Assets and liabilities recorded at fair value for which values are based on unadjusted quoted prices for identical assets or liabilities in an active market that management has the ability to access. Active markets are considered to be those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
  
Level 2—Assets and liabilities recorded at fair value for which values are based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the assets or liabilities. Substantially all of these inputs are observable in the marketplace throughout the full term of the price risk management instrument and can be derived from observable data or supported by observable levels at which transactions are executed in the marketplace.
  
Level 3—Assets and liabilities recorded at fair value for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Unobservable inputs are not corroborated by market data. These inputs reflect management's own assumptions about the assumptions a market participant would use in pricing the asset or liability.
When the inputs used to measure fair value fall within different levels of the hierarchy in a liquid environment, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company conducts a review of fair value hierarchy classifications on an annual basis. Changes in the observability of valuation inputs may result in a reclassification for certain financial assets or liabilities. Transfers between fair value hierarchy levels are recognized and reported in the period in which the transfer occurred. No transfers between fair value hierarchy levels occurred during the three or six months ended March 31,June 30, 2016 or 2015.

These items are included as "Derivatives" on the unaudited consolidated balance sheets. Significant Level 2 assumptions associated with the calculation of discounted cash flows used in the mark-to-market analysis of derivatives include each derivative contract's corresponding commodity index price, appropriate risk-adjusted discount rates and other relevant data.
The Company's deferred premiums associated with its derivative contracts are categorized as Level 3, as the Company utilizes a net present value calculation to determine the valuation. They are considered to be measured on a recurring basis as the derivative contracts they derive from are measured on a recurring basis. As derivative contracts containing deferred premiums are entered into, the Company discounts the associated deferred premium to its net present value at the contract trade date, using the Senior Secured Credit Facility rate at the trade date (historical input rates range from 1.69% to 3.56%), and then records the change in net present value to interest expense over the period from trade until the final settlement date at the end of the contract. After this initial valuation, the net present value of each deferred premium is not adjusted; therefore, significant increases (decreases) in the Senior Secured Credit Facility rate would result in a significantly lower (higher) fair value measurement for each new contract entered into that contained a deferred premium; however, the valuation for the deferred premiums already recorded would remain unaffected. While the Company believes the sources utilized to arrive at the fair value estimates are reliable, different sources or methods could have yielded different fair value estimates; therefore, on a quarterly basis, the valuation is compared to counterparty valuations and a third-party valuation of the deferred premiums for reasonableness.

b. Fair value measurement on a nonrecurring basis
The Company accounts for the impairment of long-lived assets and inventory, if any, at fair value on a nonrecurring basis. For purposes of fair value measurement, it was determined that the impairment of long-lived assets isand inventory are classified as Level 3, based on the use of internally developed cash flow models. See Note 2.g for discussion regarding the Company's impairmentsimpairment of (i) materials and supplies and line-fill for the three months ended March 31,June 30, 2016 and the three and six months ended June 30, 2015 and (ii) line-fill for the six months ended June 30, 2015.
The accounting policies for impairment of oil and natural gas properties are discussed in Note 2.f. Significant inputs included in the calculation of discounted cash flows used in the impairment analysis include the Company's estimate of operating and development costs, anticipated production of evaluated reserves and other relevant data. See Note 2.f for discussion regarding the prices used in the calculation of discounted cash flows and the Company's first-quarter 2016 and second-quarter 2015 full cost ceiling impairment.impairments.
Note 10—Net loss per share
Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share reflects the potential dilution of non-vested restricted stock awards, performance share awards and outstanding restricted stock options. For the three and six months ended March 31,June 30, 2016 and 2015, all of these potentially dilutive items were anti-dilutive due to the Company's net loss and, therefore, were excluded from the calculation of diluted net loss per share.

Note 11—Credit risk
The Company's oil, NGL and natural gas sales are made to a variety of purchasers, including intrastate and interstate pipelines or their marketing affiliates and independent marketing companies. The Company's joint operations accounts receivable are from a number of oil and natural gas companies, partnerships, individuals and others who own interests in the oil and natural gas properties operated by the Company. The Company's sales of purchased oil are made to one customer. Management believes that any credit risk imposed by a concentration in the oil and natural gas industry is offset by the creditworthiness of the Company's customer base and industry partners. The Company routinely assesses the recoverability of all material trade and other receivables to determine collectability.
The Company uses derivatives to hedge its exposure to oil and natural gas price volatility. These transactions expose the Company to potential credit risk from its counterparties. In accordance with the Company's standard practice, its derivatives are subject to counterparty netting under agreements governing such derivatives; therefore, the credit risk associated with its derivative counterparties is somewhat mitigated. See Notes 2.e, 8 and 9 for additional information regarding the Company's derivatives.
Note 12—Commitments and contingencies
a.    Litigation

From time to time the Company is involved in legal proceedings and/or may be subject to industry rulings that could bring rise to claims in the ordinary course of business. The Company has concluded that the likelihood is remote that the ultimate resolution of any pending litigation or pending claims will be material or have a material adverse effect on the Company's business, financial position, results of operations or liquidity.

b.    Drilling contractscontract

The Company has committed to several drilling contracts with variousa third partiesparty to complete its variousfacilitate the Company's drilling projects. Theplans. One of these contracts containis for a term of multiple months and contains an early termination clausesclause that requirerequires the Company to potentially pay penalties to the third partiesparty should the Company cease drilling efforts. These penaltiesThis penalty would negatively impact the Company's financial statements upon early contract termination, especially if a significant numbertermination. The future commitment of such contracts were terminated early in their respective terms. Future commitments of $3.5$3.0 million as of March 31,June 30, 2016 areis not recorded in the accompanying unaudited consolidated balance sheets. Management does not currently anticipate the early termination of any existing contractsthis contract in 2016 that would result in a substantial penalty.2016.

c.    Firm sale and transportation commitments
The Company has committed to deliver for sale or transportation fixed volumes of product under certain contractual arrangements that specify the delivery of a fixed and determinable quantity. If not fulfilled, the Company is subject to minimal volume penalties. These commitments are normal and customary for the Company's business. Future commitments of $411.8$400.2 million as of March 31,June 30, 2016 are not recorded in the accompanying unaudited consolidated balance sheets. The Company's production has been equivalent or greater than its delivery commitments during the most recent year, and management expects such production will continue to exceed the Company's future commitments. However, in certain instances, the Company has
Laredo Petroleum, Inc.
Condensed notes to the consolidated financial statements
(Unaudited)

used spot market purchases to meet its commitments in certain locations or due to favorable pricing. Management anticipates continuing this practice in the future. Also, if production is not sufficient to satisfy the Company's delivery commitments, the Company can and may use spot market purchases to fulfill the commitments.
 
d.    Federal and state regulations

Oil and natural gas exploration, production and related operations are subject to extensive federal and state laws, rules and regulations. Failure to comply with these laws, rules and regulations can result in substantial penalties. The regulatory burden on the oil and natural gas industry increases the cost of doing business and affects profitability. The Company believes that it is in compliance with currently applicable federal and state regulations related to oil and natural gas exploration and production, and that compliance with the current regulations will not have a material adverse impact on the financial position or results of operations of the Company. These rules and regulations are frequently amended or reinterpreted; therefore, the Company is unable to predict the future cost or impact of complying with these regulations.

e.    Other commitments

See Notes 2.i, 15.a and 19.b for the amount of and discussion regarding the commitments to the Company's non-consolidated variable interest entity ("VIE").
Note 13—2015 Restructuring
Following the fourth-quarter 2014 drop in oil prices, in an effort to reduce costs and to better position the Company for ongoing efficient growth, on January 20, 2015, the Company executed a company-wide restructuring and reduction in force (the "RIF") that included (i) the relocation of certain employees from the Company's Dallas, Texas area office to the Company's other existing offices in Tulsa, Oklahoma and Midland, Texas; (ii) closing the Company's Dallas, Texas area office; (iii) a workforce reduction of approximately 75 employees and (iv) the release of 24 contract personnel. The RIF was communicated to employees on January 20, 2015 and was generally effective immediately. The Company's compensation committee approved the RIF and the related severance package. The Company incurred $6.0 million in expenses during the threesix months ended March 31,June 30, 2015 related to the RIF. There were no comparative amounts recorded in the threesix months ended March 31,June 30, 2016.
Note 14—Variable interest entity
An entity is referred to as a VIE pursuant to accounting guidance for consolidation if it possesses one of the following criteria: (i) it is thinly capitalized, (ii) the residual equity holders do not control the entity, (iii) the equity holders are shielded from the economic losses, (iv) the equity holders do not participate fully in the entity's residual economics, or (v) the entity was established with non-substantive voting interests. In order to determine if a VIE should be consolidated, an entity must determine if it is the primary beneficiary of the VIE. The primary beneficiary of a VIE is that variable interest-holder possessing a controlling financial interest through: (i) its power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (ii) its obligation to absorb losses or its right to receive benefits from the VIE that could potentially be significant to the VIE. In order to determine whether the Company owns a variable interest in a VIE, a qualitative analysis is performed of the entity's design, organizational structure, primary decision makers and relevant agreements. The Company continually monitors its VIE exposure to determine if any events have occurred that could cause the primary beneficiary to change.
LMS contributed $26.7$16.0 million and $42.7 million during the three and six months ended June 30, 2016, respectively, and $14.5 million during the threesix months ended March 31, 2016 andJune 30, 2015, respectively, to Medallion Gathering & Processing, LLC, a Texas limited liability company formed on October 12, 2012, and its wholly-owned subsidiaries (together "Medallion"). See Note 19.b for discussion regarding a contribution made to Medallion subsequent to March 31,June 30, 2016. All LMS cash contributions made during the three months ended March 31, 2016 were for commitments that were fully accrued for in the Company's audited consolidated financial statements at December 31, 2015.
LMS holds 49% of Medallion's ownership units. Medallion was established for the purpose of developing midstream solutions and providing midstream infrastructure to bring oil, NGL and natural gas to market. LMS and the other 51% interest-holder have agreed that the voting rights of Medallion, the profit and loss sharing, and the additional capital contribution requirements shall be equal to the ownership unit percentage held. Additionally, Medallion requires a super-majority vote of 75% for all key operating and business decisions. The Company has determined that Medallion is a VIE. However, LMS is not considered to be the primary beneficiary of the VIE because LMS does not have the power to direct the activities that most significantly affect Medallion's economic performance. As such, Medallion is accounted for under the equity method of accounting with the Company's proportionate share of Medallion's net income (loss) reflected in the unaudited consolidated

statements of operations as "Income (loss) from equity method investee" and the carrying amount reflected in the unaudited consolidated balance sheets as "Investment in equity method investee."
During the threesix months ended March 31,June 30, 2016 and 2015, Medallion continued expansion activities on existing portions of its pipeline infrastructure in order to gather and transport additional third-party oil production. During the three months ended June 30, 2015, Medallion began recognizing revenue due to its main pipeline becoming fully operational. See Note 15.a for discussion of items included in the Company's unaudited consolidated financial statements related to Medallion.
Laredo Petroleum, Inc.
Condensed notesDuring the three months ended June 30, 2015, the Company negotiated a buyout of a minimum volume commitment to Medallion, which was related to natural gas gathering infrastructure Medallion constructed on acreage that the Company does not plan to develop. The portion of the buyout that was related to the Company's minimum volume commitment for future periods was $3.0 million and is included in the unaudited consolidated financial statements of operations in the line item "Minimum volume commitments" for the period in which the buyout was settled.

Note 18—Recent accounting pronouncements
In March, April and May 2016,the Financial Accounting Standards Board ("FASB"), issued new guidance in Topic 606, Revenue from Contracts with Customers, to address the following potential implementation issues of the new revenue standard: (a) to clarify the implementation guidance on principal versus agent considerations, (b) to clarify the identification of performance obligations and the licensing implementation guidance and (c) to address certain issues in the guidance on assessing collectibility, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The effective date and transition requirements for the amendments in these updates are the same as the effective date and transition requirements for the guidance issued in May 2014 and August 2015 to Topic 606. These updates are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements upon adoption of this standard.
In March 2016, the FASB issued new guidance in Topic 323, Investments—Equity Method and Joint Ventures, to eliminate the requirement to retroactively adopt the equity method of accounting when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence. The amendments in this update are effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. The amendments in this update should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early application of the amendments in this update is permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements upon adoption of this standard.
In March 2016, the FASB issued new guidance in Topic 718, Compensation—Stock Compensation, which seeks to simplify the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The amendments in this update are effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the applicable amendments in the same period. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements upon adoption of this standard.

Condensed notes to the consolidated financial statements

In February 2016, the FASB issued new guidance in Topic 842, Leases. The core principle of the new guidance is that a lessee should recognize the assets and liabilities that arise from leases in the statement of financial position. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. When measuring assets and liabilities arising from a lease, a lessee (and a lessor) should include payments to be made in optional periods only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. Similarly, optional payments to purchase the underlying asset should be included in the measurement of lease assets and lease liabilities only if the lessee is reasonably certain to exercise that purchase option. Reasonably certain is a high threshold that is consistent with and intended to be applied in the same way as the reasonably assured threshold in the previous leases guidance. In addition, also consistent with the previous leases guidance, a lessee (and a lessor) should exclude most variable lease payments in measuring lease assets and lease liabilities, other than those that depend on an index or a rate or are in substance fixed payments. For leases with a term of
Laredo Petroleum, Inc.
Condensed notes to the consolidated financial statements
(Unaudited)

12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. There continues to be a differentiation between finance leases and operating leases. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this update is permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements upon adoption of this standard.
In July 2015, the FASB issued new guidance in Topic 330, Inventory, which seeks to simplify the measurement of inventory. The amendments in this update apply to inventory that is measured using all methods excluding last-in, first-out and the retail inventory method. The main substantive provision of this guidance is for an entity to change the subsequent measurement of inventory, within the scope of this guidance, from LCM to the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within those fiscal years and should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements upon adoption of this standard.
In April 2015, the FASB issued new guidance in Subtopic 350-40, Intangibles—Goodwill and Other—Internal-Use Software. The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance will not change GAAP for a customer's accounting for service contracts. In addition, the guidance in this update supersedes paragraph 350-40-25-16. The amendments in this update are effective for annual periods beginning after December 15, 2015, including interim periods within those annual periods and should be applied prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The Company elected to adopt this guidance in the first quarter of 2016 on a prospective basis, and the adoption did not have an effect on its unaudited consolidated financial statements.
In May 2014, the FASB issued a comprehensive new revenue recognition standard that supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and industry-specific guidance in Subtopic 932-605, Extractive Activities—Oil and Gas—Revenue Recognition. The core principle of the new guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for transferring those goods or services. The new standard also requires significantly expanded disclosure regarding the qualitative and quantitative information of an entity's nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The standard creates a five-step model that requires companies to exercise judgment when considering the terms of a contract and all relevant facts and circumstances. The

standard allows for several transition methods: (a) a full retrospective adoption in which the standard is applied to all of the periods presented, or (b) a modified retrospective adoption in which the standard is applied only to the most current period presented in the financial statements, including additional disclosures of the standard's application impact to individual financial statement line items. This standard is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements upon adoption of this standard.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the unaudited consolidated financial statements and condensed notes thereto included elsewhere in this Quarterly Report as well as our audited consolidated financial statements and notes thereto included in our 2015 Annual Report. The following discussion contains "forward-looking statements" that reflect our future plans, estimates, beliefs and expected performance. We caution that assumptions, expectations, projections, intentions or beliefs about future events may, and often do, vary from actual results and the differences can be material. Please see "Cautionary Statement Regarding Forward-Looking Statements." Except for purposes of the unaudited consolidated financial statements and condensed notes thereto included elsewhere in this Quarterly Report, references in this Quarterly Report to "Laredo," "we," "us," "our" or similar terms refer to Laredo, LMS and GCM collectively unless the context otherwise indicates or requires. All amounts, dollars and percentages presented in this Quarterly Report are rounded and therefore approximate.
Executive overview
We are an independent energy company focused on the acquisition, exploration and development of oil and natural gas properties, and the transportation of oil and natural gas from such properties, primarily in the Permian Basin in West Texas. Since our inception, we have grown primarily through our drilling program coupled with select strategic acquisitions and joint ventures.
Our financial and operating performance for the three months ended March 31,June 30, 2016 included the following:
Oil, NGL and natural gas sales of $73.1102.5 million, compared to $118.1$125.6 million for the three months ended March 31,June 30, 2015;
Average daily sales volumes of 46,20247,667 BOE/D, compared to 47,48746,532 BOE/D for the three months ended March 31,June 30, 2015;
Net loss of $180.4$71.4 million, compared to net loss of $397.0 million, including a non-cash full cost ceiling impairment of $488.0 million, for the three months ended June 30, 2015; and
Adjusted EBITDA (a non-GAAP financial measure) of $107.8 million, compared to $117.9 million for the three months ended June 30, 2015. See page 55 for a reconciliation of adjusted EBITDA.
Our financial and operating performance for the six months ended June 30, 2016 included the following:
Oil, NGL and natural gas sales of $175.7 million, compared to $243.7 million for the six months ended June 30, 2015;
Average daily sales volumes of 46,935 BOE/D, compared to 47,007 BOE/D for the six months ended June 30, 2015;
Net loss of $251.8 million, including a non-cash full cost ceiling impairment of $161.1 million, compared to net loss of $0.5$397.5 million, including a non-cash full cost ceiling impairment of $488.0 million, for the threesix months ended March 31,June 30, 2015; and
Adjusted EBITDA (a non-GAAP financial measure) of $96.1$203.8 million, compared to $118.6$236.5 million for the threesix months ended March 31,June 30, 2015. See page 55 for a reconciliation of adjusted EBITDA.
Reserves, pricing and non-cash full cost ceiling impairment
Our results of operations are heavily influenced by oil, NGL and natural gas prices, which have significantly declined and remain at low levels. Oil, NGL and natural gas price fluctuations are caused by changes in global and regional supply and demand, market uncertainty, economic conditions and a variety of additional factors. Since the inception of our oil and natural gas activities, commodity prices have experienced significant fluctuations, and additional changes in commodity prices may affect the economic viability of, and our ability to fund, our drilling projects, as well as the economic valuation and economic recovery of oil, NGL and natural gas reserves.
Our reserves as of March 31,June 30, 2016 and December 31, 2015 are reported in three streams: oil, NGL and natural gas. Net book value of evaluated oil and natural gas properties exceededdid not exceed the full cost ceiling amount as of March 31,June 30, 2016. As such, we recordeddid not record a first-quartersecond-quarter non-cash full cost ceiling impairment of $161.1 million.impairment. See Note 2.f to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for prices used to value our reserves and additional discussion of our full cost impairment.impairments in prior periods.

We have entered into a number of derivatives, which have enabled us to offset a portion of the changes in our cash flow caused by price fluctuations on our sales of oil, NGL and natural gas as discussed in "Item 3. Quantitative and Qualitative Disclosures About Market Risk."
Potential future low commodity price impact on our full cost impairment
Oil, NGL and natural gas prices have remained low in the secondthird quarter of 2016. If prices remain at or below the current low levels, subject to numerous factors and inherent limitations, and if all other factors remain constant, we will incur an additional non-cash full cost impairment in the secondthird quarter of 2016, which will have an adverse effect on our results of operations.
There are numerous uncertainties inherent in the estimation of proved reserves and accounting for oil and natural gas properties in future periods. In addition to unknown future commodity prices, other uncertainties include (i) changes in drilling and completion costs, (ii) changes in oilfield service costs, (iii) production results, (iv) our ability, in a low price environment, to strategically drill the most economic locations in our multi-stack horizontal targets, (v) income tax impacts, (vi) potential

recognition of additional proved undeveloped reserves, (vii) any potential value added to our proved reserves when testing recoverability from drilling unbooked locations and (viii) the inherent significant volatility in the commodity prices for oil and natural gas exemplified by the large swings in recent months.
Each of the above factors is evaluated on a quarterly basis and if there is a material change in any factor it is incorporated into our internal reserve estimation utilized in our quarterly accounting estimates. We use our internal reserve estimates to evaluate, also on a quarterly basis, the reasonableness of our reserve development plans for our reported reserves. Changes in circumstance, including commodity pricing, economic factors and the other uncertainties described above may lead to changes in our reserve development plans.
We have set forth below a calculation of a potential future full cost impairment. Such implied impairment should not be interpreted to be indicative of our development plan or of our actual future results. Each of the uncertainties noted above has been evaluated for material known trends to be potentially included in the estimation of possible second-quarterthird-quarter effects. Based on such review, we determined that (i) the impact of decreased commodity prices (ii) changes in cost estimates and (iii) changes in reserves areis the only significant known variablesvariable necessary in the following scenario.
Our hypothetical second-quarterthird-quarter 2016 full cost ceiling calculation has been prepared (i) by substituting (a) $37.96$36.24 per barrel for oil, (b) $10.85$10.97 per barrel for NGL and (c) $1.61$1.64 per MMBtu for natural gas (the "Pro Forma Prices") for the respective Realized Prices as of March 31, 2016 and (ii) by incorporating a reduction in lease operating costs of 1%, updated drilling and completion costs and changes in our reserves.June 30, 2016. All other inputs and assumptions have been held constant. The Pro Forma Prices use a slightly modified Realized Price, calculated as the unweighted arithmetic average of the first-day-of-the-month price for oil, NGL and natural gas on the first day of the month for the 11 months ended MayAugust 1, 2016, with the price for MayAugust 1, 2016 held constant for the remaining twelfth month of the calculation. Based on these inputs, the implied second-quarterthird-quarter impairment would be $21$38 million. We believe that substituting the Pro Forma Prices and updating our cost and reserve estimates in our March 31,June 30, 2016 internal reserve estimates may help provide users with an understanding of the impact of known trends on our JuneSeptember 30, 2016 full cost ceiling test and in preparing our year-end reserve estimates.
Recent developments
Borrowing base redeterminationAcquisition of proved and unproved oil and natural gas properties
Subsequent to June 30, 2016, we entered into an agreement to acquire approximately 9,200 net acres of additional leasehold interests in western Glasscock and Reagan counties within our core development area (which includes production of approximately 300 net barrels of oil equivalent per day from existing vertical wells) for an aggregate purchase price of $125.0 million. As of July 13 and July18, 2016, we have closed portions of this acquisition for $92.7 million and $1.65 million, respectively. The closings on the remaining interests, which are subject to certain preferential purchase rights and consents, are expected to occur as such rights and consents are satisfied or obtained during the third and fourth quarter of 2016.
July 2016 equity offering
On July 19, 2016, we completed the sale of 13,000,000 shares of Laredo's common stock for net proceeds of $136.3 million, after underwriting discounts, commissions and offering expenses, which were used to repay borrowings under theour Senior Secured Credit Facility
Effective May 2,Facility. We granted the underwriters a 30-day option to purchase up to an additional 1,950,000 shares of Laredo's common stock on the same terms. On August 4, 2016, in connection with our regular semi-annual redeterminationthe underwriters provided notice of the borrowing base underfull exercise of the Senior Secured Credit Facility,option. The sale of the borrowing baseadditional 1,950,000 shares of Laredo’s common stock pursuant to the option is expected to close on August 9, 2016 and aggregate elected commitment amounts were each reduced to $815.0 million.

Core areas of operations
The oil and liquids-rich Permian Basin is characterized by multiple target horizons, extensive production histories, long-lived reserves, high drilling success rates and high initial production rates. As of March 31,June 30, 2016, we had assembled 132,676128,504 net acres in the Permian Basin.
Sources of our revenue
Our revenues are primarily derived from the sale of produced oil, NGL and natural gas within the continental United States and the sale of purchased oil, and our revenues do not include the effects of derivatives. For the three months ended March 31,June 30, 2016, our revenues were comprised of sales of 52%54% produced oil, 8%10% produced NGL, 8%6% produced natural gas, 30%29% purchased oil and 1% midstream services. For the six months ended June 30, 2016, our revenues were comprised of sales of 53% produced oil, 9% produced NGL, 7% produced natural gas, 29% purchased oil and 2% midstream service revenues.services. Our oil, NGL and natural gas revenues may vary significantly from period to period as a result of changes in volumes of production and/or changes in commodity prices. Our sales of purchased oil revenue may vary due to changes in oil prices.prices and market differentials. Our midstream service revenues may vary due to oil throughput fees and the level of services provided to third parties for (i) gathered natural gas, (ii) gas lift fees and (iii) water services.

Oil revenue. Our oil revenue is a function of oil production volumes sold and average sales prices received for those volumes. The decrease in oil revenue of $35.4$19.2 million, or 39%20%, for the three months ended March 31,June 30, 2016 as compared to the three months ended March 31,June 30, 2015, is mainly due to a 34%22% decrease in average oil prices realized, partially offset by a 4% increase in oil production.
The decrease in oil revenue of $54.6 million, or 29%, for the six months ended June 30, 2016 as compared to the six months ended June 30, 2015, is mainly due to a 27% decrease in average oil prices realized and a 8%2% decrease in oil production.
See "—Results of operations - midstream and marketing" for a discussion of our revenue from sales of purchased oil.
NGL and natural gas revenues. Our NGL and natural gas revenues are a function of NGL and natural gas production volumes sold and average sales prices received for those volumes. NGL revenue of $14.1 million remained mostly unchanged for the three months ended June 30, 2016 as compared to the three months ended June 30, 2015. The decrease in natural gas revenue of $3.9 million, or 30%, for the three months ended June 30, 2016 as compared to the three months ended June 30, 2015, is mainly due to a 28% decrease in average natural gas prices realized.
The decrease in NGL revenue of $4.1 million, or 31%15%, for the threesix months ended March 31,June 30, 2016 as compared to the threesix months ended March 31,June 30, 2015, is mainly due to a 36%20% decrease in average NGL prices realized.realized, partially offset by a 6% increase in NGL production. The decrease in natural gas revenue of $5.4$9.3 million, or 38%34%, for the threesix months ended March 31,June 30, 2016 as compared to the threesix months ended March 31,June 30, 2015, is mainly due to a 39%34% decrease in average natural gas prices realized.

G&A expense, excluding stock-based compensation, decreased by $1.5$2.5 million, or 9%15%, and $4.0 million, or 12%, for the three and six months ended March 31,June 30, 2016, respectively, compared to the same periodperiods in 2015. This decrease is primarily relatedOne of the main contributors to these decreases was the expense incurred for our 2013 Performance Unit Awards of $1.0 million and $1.7 million during the three and six months ended June 30, 2015, respectively. There was no comparable expense during the three and six months ended June 30, 2016. The performance unitcriteria of these awards which prior to their payouts,were satisfied on December 31, 2015, were paid during the first quarter of 2016 and were accounted for as liability awards. The associated expense for these awards decreased by $1.0 million for the three months ended March 31, 2016 compared
Other significant contributors to the same period in 2015. This fluctuation is due to the 2013 Performance Unit Awards performance criteria being satisfied at December 31, 2015, and the awards being paid at $143.75 per unit during the first quarter of 2016. As the 2013 Performance Unit Awards were fully accrued at December 31, 2015, no additional expense was recorded during the three months ended March 31, 2016. There are no outstanding awards of this type at March 31, 2016.
An additional contributor to the decreasedecreases in G&A expense, excluding stock-based compensation, isare (i) reduced personnel expenses and (ii) a decrease in professional fees of $0.4 million for the three months ended March 31, 2016 compared to the same period in 2015. This decrease is primarily due to our March 2015 Equity Offering and the issuance of our March 2023 Notes that occurred during the three months ended March 31, 2015. No comparable offerings were made during the three months ended March 31, 2016.a decrease in nonrecurring projects.
Stock-based compensation, net of amounts capitalized, decreased by $1.0$0.2 million, or 20%3%, and $1.1 million, or 10%, for the three and six months ended March 31,June 30, 2016, respectively, compared to the same periodperiods in 2015. During the three months ended March 31, 2015 we issued 1,748,517 restricted stock awards atAs a weighted-average grant priceresult of $11.90 per share to new and existing employees and non-employee directors. During the three months ended March 31, 2016, restricted stock awards, restricted stock options and performance share awards were approved by our compensation committee; however, these awards are contingent and subject to stockholder approval of the Amendment to the LTIP at our 2016 Annual Meeting of Stockholders, on May 25, 2016. These2016, the restricted stock awards, are not considered granted for accounting purposes until such Amendment is approved by our stockholders;restricted stock options and performance awards that were contingent as such, no expense has been recorded for these contingent awards during the three months endedof March 31, 2016.2016 became granted on May 25, 2016, at which time we began recording expense. For further discussion of our stock-based compensation, see Note 6 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report.
The fair values for each of our restricted stock awards issued were calculated based on the value of our stock price on the grant date in accordance with GAAP and are being expensed on a straight-line basis over their associated requisite service periods. The fair values for each of our non-qualified restricted stock options awards were determined using a Black-Scholes valuation model in accordance with GAAP and are being expensed on a straight-line basis over their associated four-year requisite service periods.
Our performance share awards are accounted for as equity awards and are included in stock-based compensation expense. The fair values of the performance share awards issued were based on a projection of the performance of our stock price relative to a peer group, defined in each performance share awards' agreement, utilizing a forward-looking Monte Carlo simulation. The fair values for each of our performance share awards will not be re-measured after their initial grant-date valuation and are being expensed on a straight-line basis over their associated three-year requisite service periods.
See Notes 2.m and 6 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional information regarding our stock and performance based compensation.
Restructuring expenses. Restructuring expenses relate towere for the first-quarter 2015 RIF that was undertaken to reduce costsexpenses and better position ourselves for future operations in a low commodity price environment. Restructuring expenses of $6.0 million were incurred during the threesix months ended March 31,June 30, 2015. No comparable expenses were recorded during the threesix months ended March 31,June 30, 2016.

We expect DD&A per BOE will further decrease in2015 and $161.1 million during the second quarter of 2016 due to our first-quarter 2016 impairment.three months ended March 31, 2016.
Impairment expense.expense. Our net book value of evaluated oil and natural gas properties exceeded the full cost ceiling amount as of March 31, 2016. As2016 and as of June 30, 2015, and as a result, we recorded a first-quarter 2016 non-cash full cost ceiling impairmentimpairments of $161.1 million. There was no comparable full cost impairment during the same period in 2015.million and $488.0 million, respectively, were recorded.

The change in fair value of derivatives outstanding for the three and six months ended March 31,June 30, 2016 compared to the same periodperiods in 2015 is the result of the changing relationship between our outstanding contract prices and the associated forward curves used to calculate the fair value of our derivatives in relation to expected market prices. In general, we experience gains during periods of decreasing market prices and losses during periods of increasing market prices. The change in gainloss on derivatives, net for the threesix months ended March 31,June 30, 2016 compared to 2015 was partially offset by proceeds received in a hedge restructuring in which we early terminated floors of certain derivative contract collars, resulting in a termination amount due to us of $80.0 million. The $80.0 million was settled in full by applying the proceeds to the premiums on two new


derivatives entered into as part of the hedge restructuring. Cash settlements received for matured derivatives are based on the cash settlement prices of our matured derivatives compared to the prices specified in the derivative contracts.

Income (loss) from equity method investee. Income from equity method investee increased by $2.7$0.8 million, or 27%, and $3.5 million, or 142%, for the three and six months ended March 31,June 30, 2016 compared to the same periodperiods in 2015. During the threesix months ended March 31,June 30, 2016, Medallion, our equity method investee, continued expansion activities on existing portions of its pipeline infrastructure in order to gather additional third-party oil production. Medallion began recognizing revenue during the first quarter of 2015 due to its main pipeline becoming fully operational. The Medallion pipeline system transported more than 83,00099,000 barrels of oil per day ("BOPD") duringand 35,000 BOPD for the three months ended March 31,June 30, 2016 compared to more than 10,000and 2015, respectively, and 91,000 BOPD in the time that the system was operationaland 25,000 BOPD during the threesix months ended March 31, 2015.June 30, 2016 and 2015, respectively.

This decrease isThese decreases are primarily due to the early redemption of the January 2019 Notes on April 6, 2015, which is partially offset by the issuance of the March 2023 Notes. The March 2023 Notes, which began accruing interest on March 18, 2015, have both a lower interest rate and a lower principal amount than the January 2019 Notes.

Our effectiveDuring the year ended December 31, 2015, we recorded a valuation allowance against our net deferred tax rate is affected by changes in valuation allowances, recurring permanent differences and by discrete items that may occur in any given year, but are not consistent from year to year. For the three months ended March 31, 2016, the effective tax rate on loss before income taxes was not meaningfulasset due to uncertainties in the valuation allowance recorded. Fortiming of the three months ended March 31, 2015,realization of our deferred tax assets. Because of continued uncertainties in the effective tax rate on income before income taxes was not meaningful due to the significant effect of discrete items on a relatively small amount of income. For the three months ended March 31, 2016,oil and gas markets, we recorded an additional valuation allowance of $57.7$83.7 million during the six months ended June 30, 2016. Due to the recording of these valuation allowances, our effective rates for the current year are not comparable to prior years. For the three and six months ended June 30, 2015, our deferredeffective tax assets due to uncertainty regarding their realization.rate was 36% and 35%, respectively. For further discussion of our valuation allowance, see Note 7 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report.
During the three and six months ended March 31,June 30, 2016 and 2015, certain shares related to restricted stock awards vested at times when the Company'sour stock price was lower than the fair value of those shares aton the time of the grant.grant date. As a result, the income tax deduction related to such shares is less than the expense previously recognized for book purposes. During the three and six months ended March 31,June 30, 2016, and 2015, no restrictedcertain stock options were exercised.exercised, for which the income tax deduction related to the options' intrinsic value is less than the expense previously recognized for book purposes. There were no stock options exercised during the three and six months ended June 30, 2015. As a result of these differences in book compensation costexpense and related tax deduction, the tax impact of these shortfalls decreased by $0.2 million and increased by $1.4$1.2 million for the three and six months ended March 31,June 30, 2016 compared to the same periodperiods in 2015.


We utilize a one-pool approach when accounting for the pool of windfall tax benefits in which employees and non-employees are grouped into a single pool. As of March 31,June 30, 2016 and 2015, we did not have any eligible windfall tax benefits to offset future shortfalls as no excess tax benefits had been recognized, and therefore the tax impact of these shortfalls is included in income tax expense for these respective periods. We expect income tax provisions for future reporting periods will be impacted by this stock compensation tax deduction shortfall; however, we cannot predict the stock compensation shortfall


impact because of dependency upon the future market price of our stock. See Notes 6.a, 6.b and 7 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional information.

Natural gas sales. These revenues are related to our midstream and marketing segment providing our exploration and production segment with processed natural gas for use in the field. The corresponding cost component of these transactions are included in "Midstream service expenses." See Note 16 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional information on the operating segments.
Midstream service revenues. Our midstream service revenues from operations increased by $7.6$6.8 million duringand $14.4 million for the three and six months ended March 31,June 30, 2016, respectively, compared to the same periodperiods in 2015. This increase is mainly due to (i) water service revenue that we began recognizing in the third quarter of 2015 and (ii) an increase in volumes of natural gas provided for natural gas lift mainly in our production corridors over the prior period.periods.


Sales of purchased oil. Sales of purchased oil was $31.6decreased by $12.4 million and $31.3$12.1 million for the three and six months ended March 31,June 30, 2016, andrespectively, compared to the same periods in 2015 respectively.primarily due to the decrease in oil prices. We purchase oil from producersthird parties in West Texas, transport the productit on the Bridgetex Pipeline and sell the productit to a third party in the Houston market.
Midstream service expenses, including minimum volume commitments. Midstream service expenses, including minimum volume commitments in 2015, increased by $3.2$5.6 million and $8.7 million for the three and six months ended March 31,June 30, 2016 compared to the


same periodperiods in 2015. Midstream service expenses primarily represent costs incurred to operate and maintain our (i) oil and natural gas gathering and transportation systems and related facilities, (ii) centralized oil storage tanks, (iii) natural gas lift, rig fuel and centralized compression infrastructure and (iv) water storage, recycling and transportation facilities. The increases are due to continued expansion of the midstream service component of our business.
Costs of purchased oil. Costs of purchased oil was $32.9decreased by $10.4 million and $31.2$8.7 million for the three and six months ended March 31,June 30, 2016, andrespectively, compared to the same periods in 2015 respectively.primarily due to the decrease in oil prices. These costs include purchasing oil from producersthird parties and transporting the purchased oilit on the Bridgetex Pipeline to the Houston market.Pipeline.
G&A. Our consolidated G&A expense has decreased for the three and six months ended March 31,June 30, 2016 compared to the same periodperiods in 2015. See "—Results of operations consolidated" for a discussion of these costs.
Depreciation and amortization. Depreciation and amortization increased by $0.5$0.1 million and $0.6 million for the three and six months ended March 31,June 30, 2016 compared to the same periodperiods in 2015 due to the continued expansion of our midstream service infrastructure.
Income (loss) from equity method investee. We own 49% of the ownership units of Medallion. As such, we account for this investment under the equity method of accounting with our proportionate share of net income (loss) reflected in the unaudited consolidated statements of operations as "Income (loss) from equity method investee" and the carrying amount reflected in the unaudited consolidated balance sheets as "Investment in equity method investee." During the year ended December 31, 2015, Medallion began recognizing revenue due to its main pipeline becoming fully operational. See Note 14 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional information regarding this investment.
Interest expense. Interest expense increased by $0.1$0.3 million and $0.4 million for three and six months ended March 31,June 30, 2016, respectively, compared to the same periodperiods in 2015. Interest is allocated to the midstream and marketing segment based on its gross property and equipment and life-to-date contributions to its equity method investee. We have expanded the midstream and marketing component of our business and built out our service facilities in the past year in addition to increasing our capital contributions to Medallion compared to prior periods, thereby increasing the interest expense that is allocated to this segment. The increase isThese increases are slightly offset by a significant decreasedecreases in our consolidated interest expense. See "—Results of operations consolidated" for a discussion of this decrease.these decreases.
Liquidity and capital resources
Our primary sources of liquidity have been cash flows from operations, proceeds from equity offerings, proceeds from senior unsecured note offerings, borrowings under our Senior Secured Credit Facility and proceeds from asset dispositions. We believe cash flows from operations (including our hedging program) and availability under our Senior Secured Credit Facility provide sufficient liquidity to manage our cash needs and contractual obligations and to fund expected capital expenditures. Our primary operational uses of capital have been for the acquisition, exploration and development of oil and natural gas properties, LMS' infrastructure development and investments in Medallion.
A significant portion of our capital expenditures can be adjusted and managed by us. We continually monitor the capital markets and our capital structure and consider which financing alternatives, including equity and debt capital resources, joint ventures and asset sales, are available to meet our future planned or accelerated capital expenditures. We may make changes to our capital structure from time to time, with the goal of maintaining financial flexibility, preserving or improving liquidity and/or achieving cost efficiency. Such financing alternatives, including capital market transactions and debt repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.
We continually seek to maintain a financial profile that provides operational flexibility. However, as evidenced by the decline in our Realized Prices used in our reserves compared to the prior year, the decrease in oil, NGL and natural gas prices may have a negative impact on our ability to raise additional capital and/or maintain our desired levels of liquidity. As of May 3,August 2, 2016, we had $605.0$745.0 million available for borrowings under our Senior Secured Credit Facility. We believe that our operating cash flow and the aforementioned liquidity sources combined with our capital budget for 2016 provide us with the financial resources to implement our planned


exploration and development activities. We use derivatives to reduce exposure to fluctuations in the prices of oil, NGL and natural gas. As of May 4,August 3, 2016, approximately 100%95% of our anticipated oil production for the last ninesix months of 2016 is hedged at a weighted-average floor price of $67.48$67.13 per Bbl and approximately 75%65% of our anticipated natural gas and NGL production for the last ninesix months of 2016 is hedged at a weighted-average floor price of $3.00 per MMBtu.

Prices used were held constant for all periods presented. Additionally, we reduced our projected oil and natural gas hedge cash proceeds by the actual cash payments required for deferred premiums for the calendar years presented.
By removing a significant portion of the price volatility associated with future production, we expect to mitigate, but not eliminate, the potential effects of variability in cash flows from operations due to fluctuations in commodity prices.
On September 15, 2015, we completed the sale of non-strategic and primarily non-operated properties and associated production totaling 6,060 net acres and 123 producing properties in the Midland Basin to a third-party buyer for a purchase price of $65.5 million. After transaction costs reflecting an economic effective date of July 1, 2015, the net proceeds were $64.8 million, net of working capital adjustments and post-closing cost adjustments.
On March 5, 2015, we completed the sale of 69,000,000 shares of Laredo's common stock at a price to the public of $11.05 per share, from which we receivedfor net proceeds of $754.2 million, after underwriting discounts, commissions and offering expenses. Entities affiliated with Warburg Pincus purchased 29,800,000 shares in the March 2015 Equity Offering, following which Warburg Pincus owned 41.0% of our common stock.
On March 18, 2015, we completed an offering of $350.0 million in aggregate principal amount of 6 1/4% senior unsecured notes due 2023, which will mature on March 15, 2023 and bear an interest rate of 6 1/4% per annum payable semi-annually in cash in arrears on March 15 and September 15 of each year, commencing September 15, 2015.
On May 16, 2016, we completed the sale of 10,925,000 shares of Laredo's common stock for net proceeds of $119.3 million, after underwriting discounts, commissions and offering expenses.


As of March 31,June 30, 2016, we had $195.0$110.3 million outstanding under our Senior Secured Credit Facility and $1.3 billion in senior unsecured notes. Prior to the semi-annual redetermination of the borrowing base under our Senior Secured Credit Facility, weWe had $805.0$704.7 million available for borrowings under our Senior Secured Credit Facility and $12.119.3 million in cash on hand for total available liquidity of $817.1$724.0 million as of March 31,June 30, 2016.
Subsequent to June 30, 2016, we completed the sale of 13,000,000 shares of Laredo's common stock for net proceeds of $136.3 million, after underwriting discounts, commissions and offering expenses, which were used to repay borrowings under our Senior Secured Credit Facility. We granted the underwriters a 30-day option to purchase up to an additional 1,950,000 shares of Laredo's common stock on the same terms. On August 4, 2016, the underwriters provided notice of the full exercise of the option. The sale of the additional 1,950,000 shares of Laredo’s common stock pursuant to the option is expected to close on August 9, 2016 and will result in net proceeds of $20.5 million, after underwriting discounts, commissions and offering expenses.
As of May 3,August 2, 2016, we had $1.5$1.4 billion in debt outstanding, $605.0$745.0 million available for borrowings under the redetermined borrowing base under our Senior Secured Credit Facility and $7.3$14.6 million in cash on hand for total available liquidity of $612.3$759.6 million. A continued decline in oil and natural gas prices will negatively impact our future borrowing base redeterminations. See “Part II, Item 5. Other Information-Item 1.01 Entry into a material definitive agreement” below for additional information regarding the reduction in the borrowing base and aggregate elected commitment amounts under our Senior Secured Credit Facility.


Our derivative positions will help us stabilize a portion of our expected cash flows from operations in the event of future declines in the price of oil and natural gas. See "Item 3. Quantitative and Qualitative Disclosures About Market Risk" below.

Cash flows provided by operating activities
Net cash provided by operating activities was $56.5$138.6 million and $26.9$114.3 million for the threesix months ended March 31,June 30, 2016 and 2015, respectively. The increase of $29.7$24.3 million during the threesix months ended March 31,June 30, 2016 compared to the same period in 2015 was largely due to the price relatedprice-related decrease in oil, NGL and natural gas revenue;revenue during 2015; however, notable cash flow changes consist of (i) an increasea decrease in impairment expense of $160.2$328.5 million, (ii) a decrease in depletion, depreciation and amortization expense of $30.5$68.4 million, and (iii) an increase in loss on derivatives, net of $49.9 million, (iv) an increase in working capital changes of $45.0 million.$47.9 million and (v) a decrease of $31.5 million related to our loss on the early redemption of our January 2019 Notes.
Our operating cash flows are sensitive to a number of variables, the most significant of which are the volatility of oil, NGL and natural gas prices and production levels. Regional and worldwide economic activity, weather, infrastructure, capacity to reach markets, costs of operations and other variable factors significantly impact the prices of these commodities. These factors are not within our control and are difficult to predict. For additional information on the impact of changing prices on our financial position, see "Item 3. Quantitative and Qualitative Disclosures About Market Risk."
Cash flows used in investing activities
Net cash used in investing activities was $134.2$243.6 million and $282.5$429.6 million for the threesix months ended March 31,June 30, 2016 and 2015, respectively. The decrease of $148.4$186.0 million is mainly attributable to a $138.6$177.5 million decrease in capital expenditures for oil and natural gas properties and a $18.5$30.7 million decrease in capital expenditures for midstream service assets. These changes were partially offset by a $12.2$28.2 million increase in investment in our equity method investee.

Capital expenditure budget
OurOn May 10, 2016, our board of directors approved aan increase to the capital expenditure budget of approximately $345.0$75.0 million. Our revised capital expenditure budget is $420.0 million for calendar year 2016, excluding acquisitions and investments in Medallion. We do not have a specific acquisition budget since the timing and size of acquisitions cannot be accurately forecasted. Since we do not direct the expansion activities of Medallion as a 49% owner, we cannot predict future capital commitments.
The amount, timing and allocation of capital expenditures are largely discretionary and within management's control. If oil, NGL and natural gas prices decline below our acceptable levels, or costs increase above our acceptable levels, we may choose to defer a portion of our budgeted capital expenditures until later periods to achieve the desired balance between sources and uses of liquidity and prioritize capital projects that we believe have the highest expected returns and potential to generate near-term cash flow. Subject to financing alternatives, we may also increase our capital expenditures significantly to take advantage of opportunities we consider to be attractive. We consistently monitor and may adjust our projected capital


expenditures in response to success or lack of success in drilling activities, changes in prices, availability of financing and joint venture opportunities, drilling and acquisition costs, industry conditions, the timing of regulatory approvals, the availability of rigs, reduction of service costs, contractual obligations, internally generated cash flow and other factors both within and outside our control.
Cash flows provided by financing activities
Net cash provided by financing activities were $58.6was $93.2 million and $795.5$343.6 million for the threesix months ended March 31,June 30, 2016 and 2015, respectively. For the threesix months ended March 31,June 30, 2016, our primary sources of cash provided by financing activities were borrowings on our Senior Secured Credit Facility and proceeds from our May 2016 Equity Offering, partially offset by payments on our Senior Secured Credit Facility. For the threesix months ended March 31,June 30, 2015, our primary sources of cash provided by financing activities were theborrowings on our Senior Secured Credit Facility, issuance of our March 2023 Notes and proceeds from our March 2015 Equity Offering, partially offset by our payment in full of our Senior Secured Credit Facility.Facility and redemption of our January 2019 Notes.

Debt
As of March 31,June 30, 2016, we were a party only to our Senior Secured Credit Facility and the indentures governing our senior unsecured notes.


Senior Secured Credit Facility. As of March 31,June 30, 2016, our Senior Secured Credit Facility, which matures November 4, 2018, had a maximum credit amount of $2.0 billion, a borrowing base of $1.15 billion,and an aggregate elected commitment amount of $1.0 billion$815.0 million and $195.0$110.3 million outstanding.
The borrowing base under our Senior Secured Credit Facility is subject to a semi-annual redetermination based on the lenders' evaluation of our oil, NGL and natural gas reserves. The lenders have the right to call for an interim redetermination of the borrowing base once between any two redetermination dates and in other specified circumstances. Effective May 2, 2016, in connection with the lenders' regular semi-annual redetermination of the borrowing base, the borrowing base and aggregate elected commitment amounts were each reduced to $815.0 million. See "Part II, Item 5. Other Information-Item 1.01 Entry into a material definitive agreement" below for additional information regarding the reduction in the borrowing base and aggregate elected commitment under our Senior Secured Credit Facility.
Principal amounts borrowed under the Senior Secured Credit Facility are payable on the final maturity date with such borrowings bearing interest that is payable, at our election, either on the last day of each fiscal quarter at an Adjusted Base Rate or at the end of one-, two-, three-, six- or, to the extent available, 12-month interest periods (and in the case of six- and 12-month interest periods, every three months prior to the end of such interest period) at an Adjusted London Interbank Offered Rate, in each case, plus an applicable margin based on the ratio of the outstanding amount on the Senior Secured Credit Facility to the elected commitment. We are also required to pay an annual commitment fee based on the unused portion of the bank's commitment of 0.375% to 0.5%.
Our Senior Secured Credit Facility is secured by a first-priority lien on certain of our assets, including oil and natural gas properties constituting at least 80% of the present value of our proved reserves owned now or in the future. Our Senior Secured Credit Facility contains both financial and non-financial covenants. We were in compliance with these ratioscovenants as of March 31,June 30, 2016 and expect to be in compliance with them for the foreseeable future.


Senior unsecured notes. The following table presents principal amounts and applicable interest rates for our outstanding senior unsecured notes as of March 31,June 30, 2016:
(in millions, except for interest rates) Principal Interest rate
January 2022 Notes $450.0
 5.625%
May 2022 Notes $500.0
 7.375%
March 2023 Notes $350.0
 6.250%
Utilizing proceeds from the March 2023 Notes and the March 2015 Equity Offering, we redeemed the January 2019 Notes in full on April 6, 2015. See Note 5.d to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for information regarding the early redemption of the January 2019 Notes.
Refer to Note 5 of our audited consolidated financial statements included in the 2015 Annual Report and Notes 5 and 19 of our unaudited consolidated financial statements included elsewhere in this Quarterly Report for further discussion of the March 2023 Notes, January 2022 Notes, May 2022 Notes, January 2019 Notes and our Senior Secured Credit Facility.
As of May 3,August 2, 2016, we had a total of $1.3 billion of senior unsecured notes outstanding and $210.0$70.0 million outstanding on the Senior Secured Credit Facility.
Obligations and commitments
As of March 31,June 30, 2016, our contractual obligations included our March 2023 Notes, January 2022 Notes, May 2022 Notes, Senior Secured Credit Facility, drilling contract commitments, firm sale and transportation commitments, derivative deferred premiums, asset retirement obligations and office and equipment leases and capital contribution commitments to our equity method investee.leases. From December 31, 2015 to March 31,June 30, 2016, the material changes in our contractual obligations included (i) an increase of $60.0 million outstanding on our Senior Secured Credit Facility, (ii) a decrease of $23.6$42.0 million on our interest obligations for our senior unsecured notes as semi-annual interest payments were made in January, March and MarchMay of 2016, (iii)(ii) a decrease of $13.8 million in our firm sale and transportation commitments, (iv) a decrease of $26.7$27.6 million in our outstanding capital contribution commitment to our equity method investee due to payments made to Medallion during first-quarter 2016, (iii) a decrease of $25.5 million in our firm sale and transportation commitments, (iv) a decrease of $24.7 million outstanding on our Senior Secured Credit Facility, (v) a decrease of $6.8$7.3 million for drilling contract commitments (on contracts other than those on a well-by-well basis) and (vi) a decrease of $6.4 million in our performance unit liability awards as the 2013 Performance Unit Awards were paid in first-quarter 2016.
Refer to Notes 2, 5, 6, 8, 9, 12, 14 and 15 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional discussion of our contractual obligations.


Non-GAAP financial measures
The non-GAAP financial measure of Adjusted EBITDA, as defined by us, may not be comparable to similarly titled measures used by other companies. Therefore, this non-GAAP measure should be considered in conjunction with net income or loss and other performance measures prepared in accordance with GAAP, such as operating income or loss or cash flow from operating activities. Adjusted EBITDA should not be considered in isolation or as a substitute for GAAP measures, such as net income or loss, operating income or loss or any other GAAP measure of liquidity or financial performance.
Adjusted EBITDA
Adjusted EBITDA is a non-GAAP financial measure that we define as net income or loss plus adjustments for deferred income tax expense or benefit, depletion, depreciation and amortization, bad debt expense, impairment expense, non-cash stock-based compensation, restructuring expenses, gains or losses on derivatives, cash settlements received for matured derivatives, cash settlements received foron early terminations ofterminated derivatives, premiums paid for derivatives, interest expense, write-off of debt issuance costs, gains or losses on disposal of assets, loss on early redemption of debt and buyout of minimum volume commitment. Adjusted EBITDA provides no information regarding a company's capital structure, borrowings, interest costs, capital expenditures, working capital movement or tax position. Adjusted EBITDA does not represent funds available for discretionary use because those funds are required for debt service, capital expenditures and working capital, income taxes, franchise taxes and other commitments and obligations. However, our management believes Adjusted EBITDA is useful to an investor in evaluating our operating performance because this measure:
is widely used by investors in the oil and natural gas industry to measure a company's operating performance without regard to items excluded from the calculation of such term, which can vary substantially from company to company depending upon accounting methods, book value of assets, capital structure and the method by which assets were acquired, among other factors;


helps investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the effect of our capital structure from our operating structure; and
 is used by our management for various purposes, including as a measure of operating performance, in presentations to our board of directors and as a basis for strategic planning and forecasting.
There are significant limitations to the use of Adjusted EBITDA as a measure of performance, including the inability to analyze the effect of certain recurring and non-recurring items that materially affect our net income or loss, the lack of comparability of results of operations to different companies and the different methods of calculating Adjusted EBITDA reported by different companies. Our measurements of Adjusted EBITDA for financial reporting as compared to compliance under our debt agreements differ.

Critical accounting policies and estimates
The discussion and analysis of our financial condition and results of operations are based upon our unaudited consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our unaudited consolidated financial statements. We believe these accounting policies reflect our more significant estimates and assumptions used in preparation of our unaudited consolidated financial statements.
In management's opinion, the more significant reporting areas impacted by our judgments and estimates are (i) the choice of accounting method for oil and natural gas activities, (ii) estimation of oil, NGL and natural gas reserve quantities and standardized measure of future net revenues, (iii) impairment of oil and natural gas properties, (iv) revenue recognition, (v) estimation of income taxes, (vi) asset retirement obligations, (vii) valuation of derivatives and deferred premiums, (viii) valuation of stock-based compensation and performance unit compensation and (ix) fair value of assets acquired and liabilities assumed in an acquisition. Management's judgments and estimates in these areas are based on information available from both internal and external sources, including engineers, geologists and historical experience in similar matters. Actual results could differ from these estimates as additional information becomes known.
There have been no material changes in our critical accounting policies and procedures during the threesix months ended March 31,June 30, 2016. For our other critical accounting policies and procedures, please see our disclosure of critical accounting policies in "Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of the 2015 Annual Report. Additionally, see Note 2 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for a discussion of additional accounting policies and estimates made by management.


Recent accounting pronouncements
See Note 18 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for information regarding recent accounting pronouncements.


Off-balance sheet arrangements
Currently, we do not have any off-balance sheet arrangements other than operating leases, a drilling contractscontract commitment and firm sale and transportation commitments, which are included in "Obligations and commitments." See Note 12 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional information.


Item 3.    Quantitative and Qualitative Disclosures About Market Risk
The primary objective of the following information is to provide forward-looking quantitative and qualitative information about our potential exposure to market risk. The term "market risk," in our case, refers to the risk of loss arising from adverse changes in oil, NGL and natural gas prices and in interest rates. The disclosures are not meant to be precise indicators of expected future losses, but rather indicators of how we view and manage our ongoing market risk exposures. All of our market risk sensitive instruments were entered into for hedging purposes, rather than for speculative trading.
Commodity price exposure
Due to the inherent volatility in oil, NGL and natural gas prices, we use derivatives, such as puts, swaps, collars and, in prior periods, basis swaps to hedge price risk associated with a significant portion of our anticipated production. By removing a portion of the price volatility associated with future production, we expect to reduce, but not eliminate, the potential effects of variability in cash flows from operations due to fluctuations in commodity prices. We have not elected hedge accounting on these derivatives and, therefore, the gains and losses on open positions are reflected in earnings. At each period-end, we estimate the fair values of our derivatives using an independent third-party valuation and recognize the associated gain or loss in our unaudited consolidated statements of operations.
The fair values of our derivatives are largely determined by estimates of the forward curves of the relevant price indices. As of March 31,June 30, 2016, a 10% change in the forward curves associated with our derivatives would have changed our net positions to the following amounts:
(in thousands) 10% Increase 10% Decrease 10% Increase 10% Decrease
Derivatives $193,960
 $271,550
 $80,867
 $158,740
As of March 31,June 30, 2016 and December 31, 2015, the fair values of our open derivative contracts were $230.0$116.4 million and $276.2 million, respectively. Refer to Notes 2.e, 8 and 9 of our unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional disclosures regarding our derivatives.
Interest rate risk
Our Senior Secured Credit Facility bears interest at a floating rate and, as of March 31,June 30, 2016, we had $195.0$110.3 million outstanding on our Senior Secured Credit Facility. Our January 2022 Notes, May 2022 Notes and March 2023 Notes bear fixed interest rates and we had $450.0 million, $500.0 million and $350.0 million outstanding, respectively, as of March 31,June 30, 2016, as shown in the table below.

Counterparty and customer credit risk
As of March 31,June 30, 2016, our principal exposures to credit risk are through receivables of (i) $230.2$121.6 million from the fair values of our open derivative contracts, (ii) $31.1$42.6 million from the sale of our oil, NGL and natural gas production that we market to energy marketing companies and refineries, (iii) $23.0$18.4 million from joint-interest partners, (iv) $18.1 million from matured derivatives and (v) $12.3$15.0 million from sales of purchased oil and other products.products and (v) $12.2 million from matured derivatives.
We are subject to credit risk due to the concentration of (i) our oil, NGL and natural gas receivables with several significant customers and (ii) our midstream service product sales receivable with one significant customer. On occasion we require our customers to post collateral, and the inability of our significant customers to meet their obligations to us or their insolvency or liquidation may adversely affect our financial results.
We have entered into International Swap Dealers Association Master Agreements ("ISDA Agreements") with each of


our derivative counterparties, who also are lenders in our Senior Secured Credit Facility. The terms of the ISDA Agreements provide the counterparties and us with rights of offset upon the occurrence of defined acts of default by either a counterparty or us to a derivative, whereby the party not in default may offset all derivative liabilities owed to the defaulting party against all derivative asset receivables from the defaulting party.
Refer to Note 11 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report for additional disclosures regarding credit risk.


Item 4.    Controls and Procedures
Evaluation of disclosure controls and procedures
As of the end of the period covered by this report, an evaluation of the effectiveness of the design and operation of Laredo's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act), was performed under the supervision and with the participation of Laredo's management, including our principal executive officer and principal financial officer. Based on that evaluation, these officers concluded that Laredo's disclosure controls and procedures were effective as of March 31,June 30, 2016. Our disclosure controls and other procedures are designed to provide reasonable assurance that the information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to Laredo's management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
Evaluation of changes in internal control over financial reporting
There were no changes in our internal control over financial reporting during the quarter ended March 31,June 30, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.


PART II

Item 1.    Legal Proceedings

From time to time we are subject to various legal proceedings arising in the ordinary course of business, including proceedings for which we may not have insurance coverage. While many of these matters involve inherent uncertainty, as of the date hereof, we are not party to any legal proceedings that we currently believe will have a material adverse effect on our business, financial position, results of operations or liquidity.

Item 1A.    Risk Factors

In addition to the other information set forth in this Quarterly Report, you should carefully consider the risks discussed in our 2015 Annual Report. There have been no material changes in our risk factors from those described in the 2015 Annual Report. The risks described in the 2015 Annual Report are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

Item 5.    Other Information

Disclosure pursuant to Section 13(r) of the Securities Exchange Act of 1934
Pursuant to Section 13(r) of the Exchange Act, we may be required to disclose in our annual and quarterly reports to the SEC, whether we or any of our "affiliates" knowingly engaged in certain activities, transactions or dealings relating to Iran or with certain individuals or entities targeted by U.S. economic sanctions. Disclosure is generally required even where the activities, transactions or dealings were conducted in compliance with applicable law. Because the SEC defines the term "affiliate" broadly, it includes any entity under common "control" with us (with the term "control" also being construed broadly by the SEC).
The description of the activities below has been provided to us by Warburg Pincus LLC ("WP"), affiliates of which: (i) beneficially own more than 10% of our outstanding common stock and/or are members of our board of directors and (ii) beneficially own more than 10% of the equity interests of, and have the right to designate members of the board of directors of, Santander Asset Management Investment Holdings Limited ("SAMIH"). SAMIH may therefore be deemed to be under common "control" with us; however, this statement is not meant to be an admission that common control exists.


The disclosure below relates solely to activities conducted by SAMIH and its affiliates that may be deemed to be under common "control" with us. The disclosure does not relate to any activities conducted by us or by WP and does not involve our or WP's management. Neither WP nor Laredo has had any involvement in or control over the disclosed activities of SAMIH, and neither WP nor Laredo has independently verified or participated in the preparation of the disclosure. Neither WP nor Laredo is representing to the accuracy or completeness of the disclosure nor do WP or we undertake any obligation to correct or update it.
We understand that one or more SEC-reporting affiliates of SAMIAH intends to disclose in their next annual or quarterly SEC report that:
(a) Santander UK plc ("Santander UK") holds two frozen savings accounts and two frozen current accounts for three customers resident in the U.K.,United Kingdom ("UK") who are currently designated by the U.S.United States ("US") under the Specially DesignedDesignated Global Terrorist ("SDGT") sanctions program. The accounts held by each customer were blocked after the customer'scustomer’s designation and have remained blocked and dormant throughoutthrough the first quarterhalf of 2016. Revenue generated by Santander UK on these accounts in the first quarterhalf of 2016 was £3.67£7.31 whilst net profits in the first quarterhalf of 2016 were negligible relative to the overall profits of Banco Santander S.A.SA.
(b) An Iranian national, resident in the U.K.,UK, who is currently designated by the U.S.US under the Iranian Financial Sanctions Regulations ("IFSR") and the Weapons of Mass Destruction Proliferators Sanctions Regulations, holdsheld a mortgage with Santander UK that was issued prior to any such designation. The mortgage account was redeemed and closed on April 13, 2016. No further drawdown has been made (or would be allowed) under this mortgage although Santander UK continuescontinued to receive repayment installments.installments prior to redemption. In the first quarterhalf of 2016, total revenue generated by Santander UK in connection with the mortgage was £201.22£434.64 whilst net profits were negligible relative to the overall profits of Banco Santander S.A.SA. Santander UK does not intend to enter into any new relationships with this customer, and any disbursements will only be made in accordance with applicable sanctions.
