THE SPIN-OFF AND BASIS OF PRESENTATION
THE SPIN-OFF AND BASIS OF PRESENTATION	NOTE 1 THE SPIN-OFF AND BASIS OF PRESENTATION The Separation and Spin-off We are an independent oil and natural gas exploration and production company operating properties exclusively within California. We were incorporated in Delaware as a wholly owned subsidiary of Occidental Petroleum Corporation (Occidental) on April 23, 2014, and we became an independent, publicly traded company on December 1, 2014. Except when the context otherwise requires or where otherwise indicated, all references to ‘‘CRC,’’ the ‘‘Company,’’ ‘‘we,’’ ‘‘us’’ and ‘‘our’’ refer to California Resources Corporation and its subsidiaries. Basis of Presentation In the opinion of our management, the accompanying financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to fairly present our financial position as of March 31, 2019 and December 31, 2018 and the statements of operations, comprehensive income, cash flows and equity for the three months ended March 31, 2019 and 2018, as applicable. We have eliminated all significant intercompany transactions and accounts. We account for our share of oil and gas exploration and development ventures, in which we have a direct working interest, by reporting our proportionate share of assets, liabilities, revenues, costs and cash flows within the relevant lines on our condensed consolidated balance sheets, statements of operations, equity and cash flows. We have prepared this report pursuant to the rules and regulations of the United States (U.S.) Securities and Exchange Commission (SEC) applicable to interim financial information, which permit the omission of certain disclosures to the extent they have not changed materially since the latest annual financial statements. We believe our disclosures are adequate to make the information not misleading. This Form 10-Q should be read in conjunction with the consolidated financial statements and the notes thereto in our Annual Report on Form 10-K for the year ended December 31, 2018.

ACCOUNTING AND DISCLOSURE CHANGES	3 Months Ended
ACCOUNTING AND DISCLOSURE CHANGES	Mar. 31, 2019
ACCOUNTING AND DISCLOSURE CHANGES
ACCOUNTING AND DISCLOSURE CHANGES	NOTE 2 ACCOUNTING AND DISCLOSURE CHANGES Recently Adopted Accounting and Disclosure Changes We adopted the Financial Accounting Standards Board's (FASB) new lease accounting rules (ASC 842), as of January 1, 2019, using the modified retrospective approach where the new lease standard is not applied to prior comparative periods, which continue to be presented under accounting standards in effect for those prior periods. Under the modified retrospective approach, we recognized right-of-use assets and lease liabilities of approximately $66 million as of the adoption date. The adoption of the new lease accounting rules did not materially impact our consolidated net earnings and had no impact on cash flows or beginning retained earnings. The new lease standard does not affect our liquidity and has no impact on our debt-covenant calculations under our 2014 Revolving Credit Facility, 2016 Credit Agreement and 2017 Credit Agreement. See Note 12 Leases for more information.

Note: For a detailed description of our credit agreements, second lien notes and senior notes, please see our most recent Form 10-K for the year ended December 31, 2018.

(a)

The 2017 Credit Agreement is subject to a springing maturity of 91 days prior to the maturity of our 2016 Credit Agreement if more than $100 million in principal of the 2016 Credit Agreement is outstanding at that time.

(b)

The Second Lien Notes require principal repayments of approximately $324 million in June 2021, $65 million in December 2021, $67 million in June 2022 and $1,593 million in December 2022.

Deferred Gain and Issuance Costs

As of March 31, 2019, net deferred gain and issuance costs were $203 million, consisting of $293 million of a deferred gain offset by $90 million of deferred issuance costs and original issue discounts. The December 31, 2018 net deferred gain and issuance costs were $216 million, consisting of $313 million of a deferred gain offset by $97 million of deferred issuance costs and original issue discounts.

2014 Revolving Credit Facility

As of March 31, 2019, we had approximately $256 million of available borrowing under our $1 billion revolving credit facility (2014 Revolving Credit Facility), before a $150 million month-end minimum liquidity requirement. Effective May 1, 2019, the borrowing base under this facility was reaffirmed at $2.3 billion. Our 2014 Revolving Credit Facility also includes a sub-limit of $400 million for the issuance of letters of credit. As of March 31, 2019 and December 31, 2018, we had letters of credit outstanding of approximately $168 million and $162 million, respectively. These letters of credit were issued to support ordinary course marketing, insurance, regulatory and other matters.

Note Repurchases

In the first quarter of 2019, we repurchased $18 million in principal amount of our 8% senior secured second lien notes due December 15, 2022 (Second Lien Notes) for $14 million in cash resulting in a pre-tax gain of $6 million, including the effect of unamortized deferred gain and issuance costs.

Fair Value

We estimate the fair value of fixed-rate debt, which is classified as Level 1, based on prices from known market transactions for our instruments. The estimated fair value of our debt at March 31, 2019 and December 31, 2018, including the fair value of the variable-rate portion, was approximately $4.8 billion and $4.5 billion, respectively, compared to a carrying value of approximately $5.3 billion in both periods.

Other

At March 31, 2019, we were in compliance with all financial and other debt covenants.

All obligations under our 2014 Revolving Credit Facility, 2017 Credit Agreement and 2016 Credit Agreement (collectively, Credit Facilities) as well as our Second Lien Notes and Senior Notes are guaranteed both fully and unconditionally and jointly and severally by all of our material wholly owned subsidiaries.

LAWSUITS, CLAIMS, COMMITMENTS AND CONTINGENCIES	NOTE 7 LAWSUITS, CLAIMS, COMMITMENTS AND CONTINGENCIES We, or certain of our subsidiaries, are involved, in the normal course of business, in lawsuits, environmental and other claims and other contingencies that seek, among other things, compensation for alleged personal injury, breach of contract, property damage or other losses, punitive damages, civil penalties, or injunctive or declaratory relief. We accrue reserves for currently outstanding lawsuits, claims and proceedings when it is probable that a liability has been incurred and the liability can be reasonably estimated. Reserve balances at March 31, 2019 and December 31, 2018 were not material to our balance sheets as of such dates. We also evaluate the amount of reasonably possible losses that we could incur as a result of these matters. We believe that reasonably possible losses that we could incur in excess of reserves accrued would not be material to our consolidated financial position or results of operations. We remain subject to examination by the IRS for calendar years 2016 and 2017. We remain subject to examination by the state of California for the years ended December 31, 2014 through 2017.

General

We use a variety of derivative instruments to protect our cash flow, operating margin and capital program from the cyclical nature of commodity prices and interest-rate movements. These derivatives are intended to help us maintain adequate liquidity and improve our ability to comply with the covenants of our Credit Facilities in case of price deterioration.

We did not have any commodity derivatives designated as hedges as of and during the three months ended March 31, 2019 and 2018. As part of our hedging program, we held the following Brent-based crude oil contracts as of March 31, 2019:

The BSP JV entered into crude oil derivatives for insignificant volumes through 2021 that are included in our consolidated results but not in the above table. The BSP JV also entered into natural gas swaps for insignificant volumes for periods through May 2021. The hedges entered into by the BSP JV could affect the timing of the redemption of the JV interest.

Interest-Rate Risk

In May 2018, we entered into derivative contracts that limit our interest rate exposure with respect to $1.3 billion of our variable-rate indebtedness. These interest-rate contracts reset monthly and require the counterparties to pay any excess interest owed on such amount in the event the one-month LIBOR exceeds 2.75% for any monthly period prior to May 4, 2021.

Fair Value of Derivatives

Our derivative contracts are measured at fair value using industry-standard models with various inputs, including quoted forward prices, and are classified as Level 2 in the required fair value hierarchy for the periods presented. We recognize fair value changes on derivative instruments in each reporting period. The changes in fair value result from the relationship between contract prices or interest rates and the associated forward curves.

The following table presents the fair values (at gross and net) of our outstanding commodity derivatives as of March 31, 2019 and December 31, 2018 (in millions):

EARNINGS PER SHARE

EARNINGS PER SHARE

NOTE 9 EARNINGS PER SHARE

We compute basic and diluted earnings per share (EPS) using the two-class method required for participating securities. Certain of our restricted and performance stock awards are considered participating securities because they have non-forfeitable dividend rights at the same rate as our common stock.

Under the two-class method, undistributed earnings allocated to participating securities are subtracted from net income attributable to common stock in determining net income available to common stockholders. In loss periods, no allocation is made to participating securities because participating securities do not share in losses. For basic EPS, the weighted-average number of common shares outstanding excludes outstanding shares related to unvested restricted stock awards. For diluted EPS, the basic shares outstanding are adjusted by adding all potentially dilutive securities.

The following table presents the calculation of basic and diluted EPS for the three months ended March 31, 2019 and 2018:

REVENUE RECOGNITION

REVENUE RECOGNITION

REVENUE RECOGNITION

NOTE 11 REVENUE RECOGNITION

We derive substantially all of our revenue from sales of oil, natural gas and natural gas liquids (NGLs), with the remaining revenue generated from sales of electricity and marketing activities related to storage and managing excess pipeline capacity.

The following is a description of our principal activities from which we generate revenue. Revenues are recognized when control of promised goods is transferred to our customers, in an amount that reflects the consideration we expect to receive in exchange for those goods.

Commodity Sales Contracts

We recognize revenue from the sale of our oil, natural gas and NGL production when delivery has occurred and control passes to the customer. Our commodity contracts are short term, typically less than a year. We consider our performance obligations to be satisfied upon transfer of control of the commodity. Transportation and processing fees incurred by us prior to control being transferred to customers are recorded as a component of other expenses, net on our condensed consolidated statements of operations.

Our commodity sales contracts are indexed to a market price or an average index price. We recognize revenue in the amount that we have a right to invoice once we are able to adequately estimate the consideration (i.e., when market prices are known). Our contracts with customers typically require payment within 30 days following invoicing.

Electricity

The electrical output of the Elk Hills power plant that is not used in our operations is sold to the wholesale power market and to a utility under a power purchase and sales agreement, which includes a capacity payment. Revenue is recognized when obligations under the terms of contracts with our customers are satisfied; generally, this occurs upon delivery of the electricity. We report electricity sales as other revenue on our condensed consolidated statements of operations. Revenue is measured as the amount of consideration we expect to receive based on average index pricing with payment due the month following delivery. Capacity payments are based on a fixed annual amount per kilowatt hour and monthly rates vary based on seasonality. Capacity payments are settled monthly. We consider our performance obligations to be satisfied upon delivery of electricity or as the contracted amount of energy is made available to the customer in the case of capacity payments.

Marketing, Trading and Other

Marketing, trading and other revenue primarily includes our activities associated with storing, transporting and marketing our production as well as third-party volumes.

To transport our natural gas as well as third-party volumes, we have entered into firm pipeline commitments. Depending on market conditions, we may have excess capacity, in which case we may enter into natural gas purchase and sale agreements with third parties. We consider our performance obligations to be satisfied upon transfer of control of the commodity. We have not incurred any significant fees or penalties related to excess capacity on these commitments.

We report our marketing and trading activities on a gross basis with purchases and costs reported in other expenses, net and sales recorded in other revenue on our condensed consolidated statements of operations.

Disaggregation of Revenue

The following table provides disaggregated revenue for the three months ended March 31, 2019 and 2018:

LEASES

LEASES

LEASES

NOTE 12 LEASES

On January 1, 2019, we adopted ASC 842 using the modified retrospective approach that requires us to determine our lease balances as of the date of adoption. Prior periods continue to be reported under accounting standards in effect for those periods. We also elected to carry forward our current accounting treatment for land easements on existing agreements. Mineral leases, including oil and natural gas leases, are not included in the scope of ASC 842.

We have long-term operating leases for commercial office space, drilling rigs, fleet vehicles and certain facilities. In considering whether a contract contains a lease, we first considered whether there was an identifiable asset and then considered how and for what purpose the asset would be used over the contract term.

Our lease liability was determined by measuring the present value of the remaining fixed minimum lease payments as of the date of adoption discounted using our incremental borrowing rate (IBR). In determining our IBR, we considered the average cost of borrowing for publicly traded corporate bond yields, which were adjusted to reflect our credit rating, remaining lease term and frequency of payments.

We elected to combine lease and non-lease components in determining fixed minimum lease payments for our drilling rigs and commercial office space. If applicable, fixed minimum lease payments were reduced by lease incentives for our commercial buildings and increased by mobilization and demobilization fees related to our drilling rigs. Certain of our lease agreements include options to renew, which we exercise at our sole discretion, and we did not include these options in determining our fixed minimum lease payments. Our lease liability does not include options to extend or terminate our leases. Our leases do not include options to purchase the leased property. Lease agreements for our fleet vehicles include residual value guarantees, none of which are recognized in our financial statements until the underlying contingency is resolved.

For all of our asset classes, we elected to keep leases with an initial term of 12 months or less off the balance sheet and have included costs related to these contracts in our short-term lease cost disclosure below. Contracts with terms of one month or less are excluded from our disclosure of short-term lease costs.

For our long-term contracts, variable lease costs were not included in the measurement of our lease balances. Variable lease costs for our drilling rigs included costs to operate, move and repair the rigs. Variable lease costs for certain of our commercial office buildings included utilities and common area maintenance charges. Variable lease costs for our fleet vehicles included other-than-routine maintenance and other various amounts in excess of our fixed minimum rental fee.

Our operating lease costs, including amounts capitalized to property, plant and equipment, for the three months ended March 31, 2019 were as follows:


	March 31,
	2019
	(in millions)
Operating lease cost	$	12
Short-term lease cost		20
Variable lease cost		5
Total lease cost	$	37

We sublease certain commercial office space to third parties where we are the primary obligor under the head lease. The lease terms on those subleases never extend past the term of the head lease and the sublease contains no extension options or residual value guarantees. Sublease income is recognized based on the contract terms and included as a reduction of operating lease cost under our head lease. For the quarter ended March 31, 2019, sublease income was not material to our condensed consolidated financial statements.

For the quarter ended March 31, 2019, we paid $9 million and $3 million for our operating lease liabilities, which were reported in net cash used in investing activities and net cash provided by operating activities in our condensed consolidated statement of cash flows, respectively.

Our right-of-use assets for operating leases, net of accumulated amortization, were approximately $54 million at March 31, 2019, which is reported in other assets on our consolidated balance sheet. Supplemental balance sheet information related to our operating leases was as follows:


	March 31,
	2019
	(in millions)
Operating lease right-of-use assets, net	$	54

Current liabilities	$	27
Long-term liabilities		27
Total operating lease liabilities	$	54

Weighted-average remaining lease term (in years)		2.9
Weighted-average discount rate (as a percentage)		11.5

As part of our company-wide consolidation of office space, we will be vacating certain office space in 2019 some of which we may sublease. Should we enter into a sublease agreement, we will evaluate the carrying value of our right-of-use asset, along with the carrying value of related tenant improvements, for impairment based on future identifiable cash flows. For the period ended March 31, 2019, we recognized an impairment of $3 million. We do not expect to terminate leases for vacated office space before the expiration of the lease term. Where we have decided to not sublease vacated commercial office space, we will shorten the useful life of the right-of-use assets and related tenant improvements to recover our remaining costs over our expected period of use. Once the leased office space is abandoned, lease costs will be classified as other non-operating expenses, net on our condensed consolidated statements of operations.

Maturities of our operating lease liabilities at March 31, 2019 are as follows:


	March 31,
	2019
	(in millions)
2019	$	27
2020		18
2021		7
2022		4
2023		2
Thereafter		6
Less: Interest		(10)
Present value of lease liabilities	$	54

We have entered into contracts for commercial office space and facilities that are under construction as of March 31, 2019. These leases are not included in our lease population at March 31, 2019 as the lease terms have not commenced because we do not control the assets during construction. We will apply the new lease standard when the asset is placed in service by us, which is expected to be January and June 2020. Payments for these contracts were included in the table of our future minimum lease payments as of December 31, 2018, which is shown below.

At December 31, 2018, future minimum lease payments for noncancelable operating leases under ASC 840 (excluding oil and natural gas and other mineral leases, utilities, taxes, insurance and common area maintenance expenses) were:


	December 31,
	2018

2020		8
2021		7

Rental expense for operating leases under ASC 840 was $2.8 million for the three months ended March 31, 2018. Rental income from subleases for the three months ended March 31, 2018 was not significant.

The difference between our statutory tax rate and our effective tax rate of zero for the periods presented includes changes to maintain our full valuation allowance against our net deferred tax assets given our recent and anticipated future earnings trends. We believe that there is a reasonable possibility that some or all of this allowance could be released in the foreseeable future. However, the amount of the net deferred tax assets considered realizable depends on the level of profitability that we are able to actually achieve.
