INDEPENDENT AUDITORS’ REPORT

To the Board of Directors of

Westmoreland Coal Company

We have audited the accompanying Statements of Assets to be Acquired and Liabilities to be Assumed of the Kemmerer Mine (the Mine) as of December 31, 2011 and 2010 and the related statements of revenues and direct operating expenses and cash flows for each of the years in the three-year period ended December 31, 2011. These financial statements are the responsibility of the Mine’s management.  Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America.  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Mine’s internal control over financial reporting. Accordingly, we express no such opinion.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

The accompanying financial statements were prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission (for inclusion in Westmoreland Coal Company’s Form 8-K/A) and are not intended to be a complete financial presentation of the Mine.

In our opinion, the financial statements referred to above present fairly, in all material respects, the assets to be acquired and liabilities to be assumed of the Kemmerer Mine as of December 31, 2011 and 2010 and its revenues and direct operating expenses and cash flows for each of the years in the three-year period ended December 31, 2011, in conformity with accounting principles generally accepted in the United States of America.

KEMMERER MINE

Notes to Financial Statements

1.   Description of Organization	Nature of Operations The Kemmerer Mine (the Mine) in Lincoln County, Wyoming was an operation of Chevron Mining, Inc. (CMI).  CMI is a wholly owned subsidiary of Chevron Corporation (the Parent).  The Mine produces high-quality sub-bituminous coal for sale to the adjacent Naughton power station, as well as various industrial customers located in the proximate geographic region.
	On January 31, 2012, Westmoreland Coal Company, through a wholly owned subsidiary, Westmoreland Kemmerer, Inc., or WKI, completed a Purchase and Sale Agreement, pursuant to which it agreed to purchase from CMI the Mine, including associated processing and shipping facilities and other related real and personal property assets located in the Hams Forks Region of southwestern Wyoming near the town of Kemmerer, Wyoming.
2.   Summary of Significant Accounting Policies	Basis of Presentation The accompanying financial statements are presented on the accrual basis of accounting and reflect the assets to be acquired, liabilities to be assumed, revenues and direct operating expenses of the Mine.  During the years presented, the Mine was not accounted for as a separate division by CMI and therefore, certain costs recorded at CMI, such as corporate and shared service expenses, interest, corporate income taxes, litigation expenses, and other indirect expenses, were not allocted to the Mine.  Furthermore, all cash receipts and payments were made by CMI.  Therefore, while the statements of cash flows present the sources and uses of cash, the cash flows were actually through CMI.
	The Statements of Assets to be Acquired and Liabilities to be Assumed and the Statements of Revenues and Direct Operating Expenses are presented in lieu of the financial statements required under Rule 3-05 of the Securities and Exchange Commission Regulation S-X.  The results presented in these financial statements may not be representative of future operations.
	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (US GAAP) requires management to make estimates and assumptions that affect reported amounts and disclosures. Accordingly, actual results could differ from those estimates.

2.   Summary of Significant Accounting Policies Continued

Inventories Inventories, which include materials and supplies used for mining coal as well as raw coal, are stated at the lower of cost or market.  Cost is determined using the average cost method.  Coal inventory costs include labor, supplies, equipment, operating overhead and other related costs.  Management periodically reviews inventories for excess supply, obsolescence, and valuations above estimated realizable amounts, and provides a reserve to reduce inventories to their net realizable values.

Property and Equipment Mineral rights are recorded at cost less accumulated depletion.  Mineral rights are depleted based upon estimated recoverable proven and probable reserves. Property and equipment are stated at cost less accumulated depreciation and amortization.  Depreciation and depletion are calculated using the straight-line method over the estimated economic useful lives of the assets, and the units of production method, as follows:

Plant and equipment	3-12 years
Mining equipment	4-10 years
Tip-load equipment	5-10 years

Management estimates the economic useful lives of property and equipment based on the expected number of years the assets will be used. Management revisits these assumptions annually and adjusts the economic useful lives if warranted.

Expenditures that materially increase values or capacities or extend useful lives of property and equipment are capitalized. Routine maintenance, repairs, and renewal costs are expensed as incurred.  Upon sale or other retirement of depreciable property, the cost and accumulated depreciation and amortization are removed from the related accounts and any gain or loss is reflected in the statements of revenues and direct operating expenses.

Impairment of Long-Lived Assets

Long-lived assets are reviewed for impairment when events or changes in circumstances indicate the book value of an asset may not be fully recoverable.  When this occurs, the Mine reviews the value assigned to long-lived assets by analyzing the anticipated, undiscounted cash flows they generate.  When the expected future undiscounted cash flows from these assets do not exceed their carrying balances, the Mine determines the estimated fair value of such assets.  Impairment is recognized to the extent the carrying amount of these assets exceeds their estimated fair value.

2.   Summary of Significant Accounting Policies Continued	Postretirement Benefit Obligation The Mine accrues the cost to provide other postretirement (OPEB) medical  benefits, as well as life insurance, other than pension benefits, over the employees’ period of active service. These costs are determined on an actuarial basis. The plan is unfunded, and the Mine and retirees share the costs.  Certain life insurance benefits are paid by the Mine.  Under the accounting standards for postretirement benefits, the Mine recognized the underfunded status as a liability on the Statements of Assets to be Acquired and Liabilities to be Assumed.
	Asset Retirement Obligation The Mine’s asset retirement obligation (ARO) primarily consists of estimated costs to reclaim surface land and support facilities in accordance with the federal and state reclamation laws as established by each mining permit.
	The Mine estimates its ARO for final reclamation and mine closure based upon detailed engineering calculations of the amount and timing of the future costs for a third party to perform the required work. These estimates are based on projected pit configurations at the end of mining and are escalated for inflation, and then discounted at a credit-adjusted risk-free rate. The Mine records an ARO asset associated with the initial recorded liability. The ARO asset is amortized based on the units-of-production method over the estimated recoverable, proven and probable reserves at the Mine, and the ARO liability is accreted to the projected settlement date. Changes in estimates occur due to revisions of Mine plans, changes in estimated costs, and changes in timing of the performance of reclamation activities, and are reflected in the period of change.
	Pension Obligation The Mine accrues the cost to provide the benefits over the employees’ period of active service for the non-contributory defined benefit pension plan it sponsors.  These costs are determined on an actuarial basis. The Mine’s Statements of Assets to be Acquired and Liabilities to be Assumed reflect the unfunded status of the defined benefit pension plan.
	Pneumoconiosis benefit obligation The Mine is self-insured for federal and state pneumoconiosis (black lung) benefits for employees. The Mine accounts for these benefits on the accrual basis. Actuarial gains and losses are recognized in the period in which they arise.

2.   Summary of Significant Accounting Policies Continued	Coal Revenues The Mine recognizes coal sales revenue at the time title passes to the customer in accordance with the terms of the underlying sales agreements.  Coal sales revenue is recognized based on the pricing contained in the contracts in place at the time that title passes. Cost of Sales Cost of sales consists primarily of product and product-related costs.
	Income Taxes Under the provisions of the Internal Revenue Code and applicable state laws, the Mine is taxed as part of a corporate consolidated income tax return, and as a result, is not directly subject to income taxes.   Therefore, no provision for income tax expense or related assets or liabilities has been included in the accompanying financial statements. The Mine is unaware of any uncertain tax positions that qualify for either recognition or disclosure in the financial statements.
	Recent Accounting Pronouncements In May 2011, accounting guidance was issued which generally aligns the principles for fair value measurements and the related disclosure requirements under US GAAP. This guidance requires additional disclosures regarding details about Level 3 fair value measurements, including quantitative information about the significant unobservable inputs used in estimating fair value, a discussion of the sensitivity of the measurement to these inputs and a description of the entity’s valuation processes. Disclosures will also be needed concerning any transfers between Level 1 and 2 of the fair value hierarchy (not just significant transfers as previous guidance required) and the hierarchy classification for items whose fair value is not recorded on the statement of assets acquired and liabilities to be assumed but is disclosed in the notes. This standard is effective for periods beginning after December 15, 2011. The Mine plans to adopt this standard in 2012.  Management believes that there will not be a significant impact on the Mine’s financial statements as a result of adopting this standard.
	Subsequent Events Management has evaluated events and transactions for potential recognition or disclosure subsequent to December 31, 2011 and through April 12, 2012, which is the date the financial statements were available to be issued.

5.  Postretirement Benefit      Obligation Continued In March 2010, the Patient Protection and Affordable Care Act, or PPACA was enacted, potentially impacting the Mine’s costs to provide healthcare benefits to current employees and their dependents upon retirement. The PPACA has both short-term and long-term implications on healthcare benefit plan standards. Implementation of this legislation is planned to occur in phases, with plan standard changes that occurred in 2010, but will continue to expand benefit obligations through 2018. Beginning in 2018, the PPACA will impose a 40% excise tax on employers to the extent that the value of their healthcare plan coverage exceeds certain dollar thresholds. The Mine will continue to evaluate the impact of the PPACA in future periods as additional information, interpretations and guidance becomes available.  

The following table sets forth the actuarial present value of postretirement medical benefit obligations and amounts recognized in the Mine’s financial statements as of and for the years ended December 31:

	2011		2010
Change in benefit obligations:
Net obligation at beginning of year	$	42,686,000	$	34,177,000
Service cost		1,676,000		928,000
Interest cost		2,241,000		1,965,000
Actuarial loss		9,067,000		5,616,000
Net obligation at end of year	$	55,670,000	$	42,686,000

In 2011, the Mine’s postretirement medical benefit liabilities increased approximately $13.0 million primarily from decreases in discount rates and updated cost projections.

The components of net periodic postretirement medical benefit cost are as follows for the years ended December 31:

	2011		2010		2009
Components of net periodic benefit cost:
Service cost	$	1,676,000	$	928,000	$	901,000

5.  Postretirement Benefit Obligation Continued Assumptions The weighted-average assumptions used to determine the benefit obligations were as follows as of December 31:

	2011			2010
Discount rate		4.25	%		5.25	%

The discount rate assumption used to determine the postretirement benefit plan obligation and expense reflect the prevailing rates available on high-quality, fixed-income debt instruments.  This rate was based on a cash flow analysis that matched estimated future benefit payments to the Citigroup Pension Discount Yield Curve as of December 31, 2011 and 2010.

The weighted-average assumptions used to determine the net periodic benefit cost were as follows as of December 31:

	2011			2010			2009
Discount rate		5.25	%		5.75	%		6.25	%
Measurement date	January 1, 2011			January 1, 2010			January 1, 2009

The following presents information about the assumed health care trend rate:

	2011			2010
Health care cost trend rate assumed for next fiscal year		6.5% - 8.00	%		8.50	%
Average assumed rate to which the cost trend is to decline (ultimate trend rate)		5.00	%		5.00	%
Year that the rate reaches the ultimate trend rate		2023			2018

The effect of a one percentage change on the health care cost trend rate used to calculate periodic postretirement medical benefit costs and the related benefit obligation are summarized in the table below:

	1% Increase		1% Decrease
Effect on service and interest cost components	$	1,109,000	$	(816,000	)
Effect on postretirement medical benefit obligation		8,573,000		(6,966,000	)

7.  Pension Obligation Continued	Assumptions - Continued The discount rate is adjusted annually based on an A corporate bond index adjusted for the difference in the duration of the bond index and the duration of the benefit obligations. This rate is calculated using a yield curve, which is developed using the average yield for bonds in the tenth to nineteenth percentiles, which excludes bonds with outlier yields.

Plan Assets

The pension plan’s investments were combined with the investments of Chevron Master Pension Trust (Master Trust) to maximize administrative efficiencies of CMI. The Master Trust also included the investment assets of other retirement plans sponsored by CMI. Investment income, investment management fees and other direct expenses relating to the Master Trust were allocated to the individual plans based upon the average daily balances. The Plan’s interest in the Master Trust was 0.46% and 0.45% as of December 31, 2011 and 2010, respectively.

The primary investment objectives of the pension plan are to achieve the highest rate of total return within prudent levels of risk and liquidity, to diversify and mitigate potential downside risk associated with the investments, and to provide adequate liquidity for benefit payments and portfolio management.

The Master Trust has an Investment Committee that regularly meets during the year to review the asset holdings and their returns. To assess the plans’ investment performance, long-term asset allocation policy benchmarks have been established.

For the Master Trust, the Chevron Board of Directors has established the following approved asset allocation ranges: Equities 40–70 percent, Fixed Income and Cash 20–65 percent, Real Estate 0–15 percent, and Other 0–5 percent. To mitigate concentration and other risks, assets are invested across multiple asset classes with active investment managers and passive index funds. CMI does not prefund the OPEB obligations.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly hypothetical transaction between market participants at a given measurement date. Valuation techniques used must maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value and is defined as:

Level 1, defined as observable inputs such as quoted prices in active markets for identical assets. Level 1 assets include available-for-sale equity securities generally valued based on independent third-party market prices. Level 2, defined as observable inputs other than Level 1 prices. These include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

7.  Pension Obligation Continued	U.S. equities include investments in Chevron’s common stock in the amount of $35 at December 31, 2011, and $38 at December 31, 2010. Collective trusts/mutual funds for U.S. plans are entirely index funds. For these index funds, the Level 2 designation is partially based on the restriction that advance notifications of redemptions, typically two business days, is required.
	The year-end valuations of the U.S. real estate assets are based on internal appraisals by the real estate managers, which are updates of third-party appraisals that occur at least once a year for each property in the portfolio.
	The other assets class includes net payables for securities not yet settled (level 1); dividends and interest and tax-related receivables (level 2); and insurance contracts and investments in private-equity limited partnerships (level 3).
	The following tables set forth information summarizing the changes in fair value of the Plan’s Level 3 assets for the years ended December 31, 2011 and 2010 (in millions):

Beginning balance as of January 1, 2010	$	530
Actual return on plan assets:
Assets held at the reporting date		32
Assets sold during the period		1
Purchases, sales, and settlements		86
Balance as of December 31, 2010		649
Actual return on plan assets:
Assets held at the reporting date		102
Assets sold during the period		(1	)
Purchases, sales, and settlements		147
Ending balance as of December 31, 2011	$	897

Contributions

Contributions of approximately $287,000 related to the 2011 plan year, and $1,883,000 related to the 2012 plan year, are expected to be made to the pension plan for 2012.

2013		2,395,000
2014		2,632,000
2015		2,820,000
2016		2,980,000
2017 - 2021		17,170,000
	$	30,336,000

The benefits expected to be paid are based on the same assumptions used to measure the pension benefit obligation as of December 31, 2011 and include estimated future employee service.

8.  Pneumoconiosis Benefit Obligation The PPACA amended previous legislation related to black lung disease, providing automatic extension of awarded lifetime benefits to surviving spouses and providing changes to the legal criteria used to assess and award claims.  The Mine has not determined what, if any, additional impact may result from these claims due to lack of claims experience under the new legislation and court rulings interpreting the new provisions. The Mine will continue to evaluate the impact of the PPACA in future periods as additional information, interpretations, guidance and claims experience becomes available.

The Mine’s black lung obligation was $2,421,000 and $2,284,000 as of December 31, 2011 and 2010, respectively.

The discount rate used in determining the actuarial present value of the pneumoconiosis benefit obligation as of December 31, 2011 and 2010, was 6%.

Production Commitment

In July 2010, the Mine entered into a production commitment with Customer A. Under the agreement, the Mine is obligated to sell between 2.4 million tons and 2.85 million tons of coal to Customer A per year.  The agreement expires in December 2021. The base price is $35.662 per ton up to 2.4 million tons and $20.00 per ton between 2.4 million and 2.85 million tons and is subject to quarterly adjustments.

In addition, the Mine has entered into production commitments with approximately 11 other customers in which they are obligated to sell in aggregate between 1,907,000 and 4,161,000 tons of coal with a base price between $15.70 and $65.00 per ton per year.  The production commitments were entered into beginning in 2004 and expiring in 2020.

Purchase Commitment

The Mine has a purchase commitment to buy a specific number of tires per year through 2014.  The estimated annual amount of the purchase commitment is $3.5 million and may vary depending on the actual cost of the tires at the time of purchase.

Leases

The Mine leases certain of its coal reserves from third parties and pays royalties based on either a per ton rate or as a percentage of revenues received. Royalties charged to expense under all such lease agreements amounted to approximately $4.0 million, $6.8 million, and $6.0 million for the years ended December 31, 2011, 2010, and 2009, respectively.
