Basis of Presentation

The accompanying financial statements have been prepared in accordance with the instructions for Form 10-Q and do not necessarily include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of U.S. Bank National Association, as sole trustee of the Trust (the “Trustee”), all adjustments necessary for a fair presentation have been included. For further information, refer to the financial statements and footnotes included in the Trust’s Annual Report on Form 10-K for the year ended December 31, 2011.

Summary of Significant Accounting Policies

The financial statements of the Trust, as prepared on the modified cash basis, reflect the Trust’s assets, liabilities, trust corpus, and distributable income as follows:

1. Royalty income and interest income are recognized in the month in which amounts are received by the Trust.

2. Trust expenses, consisting principally of routine general and administrative costs, include payments made during the accounting period.

3. Reserves for liabilities that are contingent or uncertain in amount may also be established if considered necessary.

4. Net royalty and overriding royalty interests that are producing properties are amortized using the unit-of-production method. This amortization is shown as a reduction of Trust corpus.

5. Distributions to Unit Holders are recognized when declared by the Trustee.

6. Production withholding taxes withheld from Unit Holder distributions and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from royalty income in the statement of distributable income.

The financial statements of the Trust differ from financial statements prepared in conformity with United States generally accepted accounting principles (GAAP) because of the following:

Table of Contents

These statements differ from financial statements prepared in accordance with GAAP and were prepared on the modified cash basis of reporting, which is considered to be the most meaningful because Distributions to Unit Holders are based on net cash receipts. This comprehensive basis of accounting, other than GAAP, corresponds to the accounting permitted for royalty trusts by the U.S. Securities and Exchange Commission as specified by Staff Accounting Bulletin Topic 12E, Financial Statements of Royalty Trusts.

The Trust considers all highly liquid financial instruments with original maturities of three months or less when purchased to be cash equivalents.

The Trust was organized to provide an efficient, orderly and practical means of administering the income received from royalty interests and is administered by the Trustee. Pursuant to the terms of the Trust Indenture, the Trust pays the Trustee $80,000 per year. The Trustee may readjust this fee annually in its sole discretion. In the first quarter of fiscal year 2011, the Trust paid the fourth quarter 2010 Trustee fees of $20,000 and the first quarter 2011 Trustee fees of $20,000. In the first quarter of fiscal year 2012, the Trust paid the fourth quarter 2011 Trustee fees of $20,000 and the first quarter 2012 Trustee fees of $20,000. In the second quarter of 2012, the Trust paid the second quarter Trustee fees of $20,000. The Trust did not pay the Trustee fees of $20,000 for the second quarter of 2011 due to insufficient royalty income.

We have evaluated the Trust activity and have concluded that there are no material subsequent events requiring additional disclosure or recognition in these financial statements.

Item 2. Trustee’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview.

Kiewit Royalty Trust (the “Trust”) is a royalty trust with royalty and overriding royalty interests in certain coal leases. The Trust was formed for the purposes of administering the income received from such coal leases and distributing such income (together with interest earned thereon, if any, less payment of or provision for obligations) to the holders of the units of beneficial interest.

During the three-month and six-month periods ended June 30, 2012, the Trust received a total of $73,394 and $620,823, respectively, of royalty and overriding royalty payments, net of production expenses. The following tables reflect the royalty and overriding royalty payments, net of production expenses, received by the Trust at the following mines:

Decker Mine. Royalty and overriding royalty amounts received by the Trust from the Decker Mine slightly increased to $23,394 during the second quarter of 2012, as compared to $23,241 received during the same period in 2011. The Decker Mine includes West Decker and East Decker Mine leases. Of the Decker Mines, the primary producer currently is an East Decker Mine. The changes during the period were the net result of changes in the relative amounts of coal mined, which was a normal result of the execution of a mining plan encompassing several coal leases. Seasonal fluctuations occur in the relative amounts of coal mined under the leases with a majority of the royalty payments being received during the first and third calendar quarters of the year.

Spring Creek Mine. The Trust received a payment of $50,000 at the end of the second quarter of 2012 from the Spring Creek Mine. No royalties were received from the Spring Creek Mine during the first six months of 2011. The first $50,000 royalty payment from this mine is paid at the end of June or beginning of July each year, and the remaining royalties with respect to this mine are typically paid by the mine operators on an annual basis during the second half of the calendar year.

Interest Income. Historically, the Trust earned interest on the royalty payments prior to the distribution to the Unit Holders. However, the Trust did not earn any interest during the six months ended June 30, 2011, because of the significant cuts in interest rates by the Federal Reserve. Recently interest rates have slightly increased, and during the six months ended June 30, 2012, the Trust earned a nominal amount of interest.

Trust Expenses. Trust expenses increased to $91,134 for the first six months of 2012, as compared to $59,917 for the same period in 2011. The Trust did not pay the Trustee fee of $20,000 for the second quarter of 2011 due to insufficient royalty income, which substantially decreased the amount of expenses incurred by the Trust in the first half of 2011. The payment of the Trustee fee would have increased Trust expenses for such period. Trust expenses included fees of the Trustee, accountants, attorneys, and other professionals that the Trustee employs in the administration of the Trust.

During the first quarter of 2012, the trust expenses included the Trustee’s fees for the fourth quarter of 2011 of $20,000 and first quarter of 2012 of $20,000. The fourth quarter fee generally is paid in the fourth quarter; however, the Trustee had insufficient royalty income, and the fee was not paid until the Trust had sufficient royalty income. In the fourth quarter of 2010, the Trust also did not have sufficient income to pay the Trustee’s fees for the fourth quarter. The Trust paid the fourth quarter 2010 fee of $20,000 and first quarter 2011 fee of $20,000 in the first quarter of 2011.

During the three month period ended June 30, 2012, trust expenses increased to $38,330 from $11,075 during the same three month period in 2011. The second quarter Trustee fee of $20,000 was paid during the second quarter of 2012, but not in the second quarter of 2011 due to insufficient royalty income. The remaining increase in trust expenses was due to an increase in professional fees.

Liquidity and Capital Resources. The Trust’s primary source of liquidity is the receipt of royalty payments. In accordance with the provisions of the Trust Indenture, generally all income received by the Trust, net of Trust expenses and any amounts placed in reserves, is distributed to the Unit Holders on a quarterly basis. During the quarter ended June 30, 2012, the Trust did not establish any reserves.

Change in Trust Corpus. During the first six months of 2012, the trust corpus remained unchanged.

Off-Balance Sheet Arrangements. As required by the Trust Indenture, the Trust is intended to be passive in nature and the Trustee does not have any control over or any responsibility relating to the operation of the mines under which the Trust has any royalty interests and overriding royalty interests. The Trustee has powers to collect and distribute proceeds received by the Trust and pay Trust liabilities and expenses and its actions have been limited to those activities. As a result, the Trust has not engaged in any off-balance sheet arrangements.

Critical Accounting Policies and Estimates. The Trust’s financial statements are prepared on a modified cash basis of accounting, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America, and as such there are no critical accounting policies or estimates.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this Form 10-Q, the officer of the Trustee conducted an evaluation of the Trust’s disclosure controls and procedures (as defined in Rules 13a-15(e) of the Securities Exchange Act of 1934). Based upon this evaluation, the officer of the Trustee concluded that the Trust’s disclosure controls and procedures were effective in timely alerting him of any material information relating to the Trust that is required to be disclosed by the Trust in the reports it files or submits under the Securities Exchange Act of 1934.

Changes in Internal Control Over Financial Reporting. There were no changes in the Trust’s internal control over financial reporting (as defined in Rule 13a-15(f) of the Securities Exchange Act of 1934) that occurred during the Trust’s most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting.

Limitations on Controls. The Trustee does not expect that the Trust’s disclosure controls and procedures of the Trust’s internal control over financial reporting will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Trust have been detected.
