NOTES TO THE FINANCIAL STATEMENTS

AS OF AND FOR THE YEARS ENDED DECEMBER 31,   2015 and 2014

The following description of the Union Pacific Agreement Employee 401(k) Retirement Thrift Plan (the “Plan”) is provided for general information only. Participants should refer to the Plan document for more complete information.

General  — The Plan is a defined contribution plan covering employees of the Union Pacific Railroad Company and its railroad affiliates (the “Company”) who are represented for the purposes of collective bargaining by a rail union to which eligibility to participate in the Plan has been extended. The Plan covers employees who have completed one year of service or were employees as of the effective date of the Plan, July 1, 1990. Vanguard Fiduciary Trust Company (“VFTC”) serves as the trustee of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Contributions  — Each year, participants may contribute 2% to 75% of their eligible compensation on a salary deferral basis subject to limitations specified in the Internal Revenue Code (the “Code”). A participant may designate all or a portion of his/her pre-tax contribution as a Roth contribution. Participants may also contribute 1% to 75% of their eligible compensation on an after-tax basis. Combined after-tax , Roth and pre-tax contributions may not exceed 75% of eligible compensation. Participants who have attained age 50 before the end of the plan year are eligible to make catch-up contributions. The Company contributes to the Plan on behalf of each participant who contributes to the Plan and is represented by a rail union that has negotiated a matching contribution with the Company. The Company’s matching contribution is an amount equal to 50% of the participant’s pre-tax, Roth and after-tax contributions, for the payroll period that are not in excess of 6% of the participant’s eligible compensation for the payroll period. Participants may direct the investment of contributions made to their account into various investment options offered by the Plan or may elect to participate in the Vanguard Advisers Managed Account Program (“Managed Account Program”). The Managed Account Program is a program in which certain participants may delegate on-going, discretionary investment management decisions with respect to their account to Vanguard Advisers, Inc. If a participant does not provide investment direction with respect to contributions made to their account, such contributions are invested in a default investment option designated under the Plan.

Participant Accounts  — Individual accounts are maintained for each Plan participant. Each participant’s account is credited with the participant’s contributions, employer-matching contributions (if applicable) and an allocation of the Plan’s earnings (or losses) based upon the type of investments selected and their performance. The allocations are based on each participant’s account balance by investment type. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Vesting  — Participants at all times have a 100% vested interest in their accounts.

Distributions to Participants  — Following a participant’s termination of employment, a distribution of benefits will be made upon request in a single sum payment. Distributions of the portion of a participant’s account invested in the Union Pacific Common Stock Fund are distributed in cash unless shares of stock are elected at the time of distribution. In-kind distributions are lump sum and any fractional shares are

distributed in cash. A terminated participant may defer distribution until the earlier of the participant’s required beginning date, as defined in the Plan, or the participant’s death. If distribution is deferred until the participant’s required beginning date, the participant may elect distribution either in a single sum or in the form of monthly, quarterly, semi-annual or annual installments. Such single sum distribution must be made (or installments begin) no later than the participant’s required beginning date. If the participant remains employed with the Company after attaining age 70 1/2, the participant must either take a single sum distribution or begin installment payments no later than the April 1 of the year following the year in which the participant terminates employment.

In-service withdrawals, including withdrawals of rollover contributions, hardship withdrawals, and withdrawals on and after age 59 1/2 may be made by a participant from their account in accordance with the Plan’s provisions.

Plan Administration  — Prior to November 1, 2014, the Plan was administered by the Vice President, Human Resources of Union Pacific Railroad Company. From November 1, 2014, through March 31, 2016, the Plan wa s administered by the Assistant Vice President ,   Compensation & Benefits, Union Pacific Railroad Company. Effective April 1, 2016, the Plan is administered by the Vice President, Human Resources of Union Pacific Railroad Company. Investment management fees for the Plan’s investment options are netted against investment earnings. Except to the extent the Company is obligated, pursuant to the terms of a collective bargaining agreement, to pay expenses incurred for Plan administration, such expenses, including participant recordkeeping expenses, are payable from Plan assets. Effective July 1, 2014, participant recordkeeping expenses are no longer netted against Plan investment earnings.

Basis of Accounting  — The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP).

Use of Estimates  — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits and changes therein and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Risks and Uncertainties  — The Plan utilizes various investment instruments. Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the value of the participants’ account balances and amounts reported in the financial statements.

Investment Valuation and Income Recognition  — Investments are reported at fair value with the exception of fully benefit-responsive investment contracts. Fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Note 3 for discussion of fair value measurements.

Dividend income is recorded as of the ex-dividend date. Dividends are reinvested in a related participant fund. Interest income is recorded on the accrual basis. Purchases and sales of securities are recorded as of the trade date. Net appreciation (depreciation) includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

For contracts held by a defined contribution plan, contract value is the relevant measurement attribute for that portion of the net assets available for benefits attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The statements of net assets available for benefits present the fully benefit-responsive investment contracts at contract value. The statements of changes in net assets available for benefits are also prepared on a contract value basis.

Administrative Expenses  — Administrative expenses of the Plan are paid as described in t he section “Plan Administration ” in Note 1. All investment management and transaction fees directly related to the Plan investments are paid by the Plan. Management fees and operating expenses charged to the Plan for investments are deducted from income earned on a daily basis and are not separately reflected. Consequently, management fees and operating expenses are reflected as a reduction of investment return for such investments. Plan administrative expenses of $ 928,504 and $764,526   were paid in 201 5 and 2014 , respectively .

Distributions to Participants  — Distributions are recorded when paid. There were no amounts allocated to accounts of persons who have elected to withdraw from the Plan but have not yet been paid at December 31, 2015 or 2014 .

New Accounting Standards —   In May 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-07, Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per share (or Its Equivalent). The ASU eliminates the requirement to categorize, within the fair value hierarchy, investments whose fair values are measured at net asset value. Instead, an entity would be required to include those investments as a reconciling item so that the total fair value amount of investments in the disclosure is consistent with the fair value investment balance on the statement of net assets available for benefits. The ASU is effective for fiscal years beginning after December 15, 2015, with early adoption permitted. The guidance will be applied retrospectively. The Plan has adopted the new guidance in 2015. Other than the change to disclosures, the adoption of this standard did not have a material impact on the financial statements.

In July 2015, the FASB issued ASU 2105-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): (Part I) Fully Benefit-Responsive Investment Contracts,   (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient . Part I of the ASU eliminates the requirements to measure the fair value of fully benefit-responsive investment contracts and provide certain disclosures. Contract value is the only required measure for fully benefit-responsive investment contracts. Part II of the ASU eliminates the requirements to disclose individual investments that represent 5 percent or more of net assets available for benefits and the net appreciation or depreciation in fair value of investments by general type. It also simplifies the level of disaggregation of investments that are measured using fair value. Plans will continue to disaggregate investments that are measured using fair value by general type; however, plans are no longer required to also disaggregate investments by nature, characteristics and risks. Further, the disclosure of information about fair value measurements shall be provided by general type of plan asset. Part III of the ASU allows a plan with a fiscal year end that does not coincide with the end of a calendar month to measure its investments and investment-related accounts using the month end closest to its fiscal year end. The ASU is effective for fiscal years beginning after December 15, 2015. Parts I and II are to be applied retrospectively. Part III is to be applied prospectively. The Plan has adopted Parts I and II in 2015. Part III is not applicable to the Plan. The adoption resulted in the reclassification of the adjustment from fair value to contract value for fully benefit-responsive investment contracts totaling $3,729,538, in the statements of net assets available for benefits. Certain historical disclosures that are no longer required were removed.

Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures , established a single authoritative definition of fair value, set a framework for measuring fair value, and requires additional disclosures about fair value measurements. In accordance with ASC 820, the Plan classifies its investments into a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:

Level 1  — Quoted market prices in active markets for identical assets or liabilities.

Level 2  — Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3  — Unobservable inputs that are not corroborated by market data.

Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Asset Valuation Methodologies  — Valuation methodologies maximize the use of relevant observable inputs and minimize the use of unobservable inputs. The following is a description of the valuation methodologies used to determine the fair value for each investment category and the fair value hierarchy tier to which each investment category has been assigned.

Company Stock Funds  — These funds are invested exclusively in common stock issued by Union Pacific Corporation (the “Corporation”) along with a small amount of cash held for liquidity purposes. The unit price (value) for shares of these funds is computed daily based on the closing price of Union Pacific common stock on the New York Stock Exchange, the number of shares of stock held by the funds, and the amount of cash held in the funds. Employer stock funds are classified as Level 2 investments.

Mutual Funds (Including the Domestic Stock Funds, International Stock Fund, Balanced Funds, Money Market Fund, and Bond Fund)  — The shares of mutual funds are actively traded in a public exchange and the quoted prices at which these securities trade in the exchange are readily available. These quoted prices are used to determine the net asset values of mutual fund shares held by the Union Pacific Corporation Master Trust (“Master Trust”) at year-end .

Common/Collective Trusts — The Target Retirement Trusts invest in Vanguard mutual funds. While the trust units are not actively traded in a public exchange, the underlying mutual fund investments held by the trusts are actively traded in a public exchange. The readily observable quoted share prices for the underlying mutual fund investments are used to determine the net asset value of the trusts at year-end .

A summary of the Master Trust assets measured at fair value on a recurring basis set forth by level within the fair value hierarchy as of December 31, 2015 and 2014 , is presented in the following tables:







*   In accordance with Subtopic 820-10, certain investments that were measured at net asset value per share (or its equivalent) have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the line items presented in the statement of net assets available for benefits.

Transfers between Levels — The availability of observable market data is monitored to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. The Plan’s policy is to recognize transfers between the levels at the actual date of the event.

The Plan evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total net assets available for benefits. For the years ended December 31, 2015 and 2014 , there were no transfers in or out of Levels 1, 2, or 3.

The following tables summarize investments for which fair value is measured at net asset value as of December 31, 2015 , and 2014 , respectively. There are no participant redemption restrictions for these investments; the redemption notice period is applicable only to the Plan.









At December 31, 2015 and 2014 , the Plan participated in a Master Trust with other retirement plans sponsored by the Corporation or its subsidiaries. The investment assets of the Master Trust are held at VFTC. Use of the Master Trust permits the commingling of the trust assets of a number of benefit plans of the Corporation and its subsidiaries for investment and administrative purposes. Although assets are commingled in the Master Trust, VFTC maintains supporting records for the purpose of allocating the net investment income (loss) of the investment accounts to the various participating plans. The investment valuation methods for investments held by the Master Trust are discussed in Note 3.

The Plan’s interest in the Master Trust, as a percentage of net assets held by the Master Trust, as of December 31, 2015 and 2014 , is presented in the following tables:



Investment income (loss) for the Master Trust for the years ended December 31, 2015 and 2014 , is as follows:



While the Plan participates in the Master Trust, each participant’s account is allocated earnings (or losses) consistent with the performance of the funds in which the participant’s account is invested. Therefore, the investment income (loss) of the Master Trust may not be allocated evenly among the plans participating in the Master Trust.

The Master Trust provides to participants a stable value investment option (the Union Pacific Fixed Income Fund) that includes traditional Guaranteed Investment Contracts (GICs) and synthetic GICs. These contracts meet the fully benefit-responsive investment contract criteria and therefore are reported at contract value. Contract value is the relevant measure for fully benefit-responsive investment contracts because this is the amount received by participants if they were to initiate permitted transactions under the terms of the Plan. Traditional GICs are maintained in a general account by VFTC, which is credited with earnings on the underlying investments and charged for participant withdrawals and administrative expenses. Synthetic GICs simulate the performance of a traditional GIC through an issuer’s guarantee of a specific interest rate (a benefit-responsive wrapper contract) and a portfolio of financial instruments that are owned by the Master Trust. The crediting interest rate is based on a formula agreed upon with the issuer, but may not be less than 0%. Such interest rates are reviewed on a quarterly basis for resetting. The crediting rate of these contracts will track current market yields on a trailing basis.

The following table represents the disaggregation of contract value between types of investm ent contracts held by the Plan:





The Plan obtained a tax determination letter dated August 29, 2013, in which the Internal Revenue Service (IRS) stated that the Plan, as then designed, was in compliance with the applicable requirements of the Code. Although the Plan has been amended since receiving the determination letter, the Company and Plan management believe that the Plan and related Master Trust are currently designed and being operated in compliance with the applicable requirements of the Code. Therefore, no provision for income taxes has been included in the Plan’s financial statements.   Plan management made a Voluntary Compliance Program submission to the IRS on December 30, 2015.  The submission seeks to correct the failure to distribute the segregated account of an alternate payee of a deceased participant in accordance with the Plan’s terms intended to comply with the required minimum distribution rules of Section 401(a)(9) of the Code and the regulations thereunder.  The Plan has not yet received a compliance statement from the IRS with respect to this submission. 

GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes the Plan and the related Master Trust are no longer subject to income tax examinations for years prior to 201 2 .

Although it has not expressed any intent to do so, the Company has the right under the Plan, at any time, to terminate the Plan subject to the provisions of ERISA. Regardless of such actions, the principal and income of the Plan remain for the exclusive benefit of the Plan’s participants and beneficiaries. The Company may direct VFTC either to distribute the Plan’s assets to the pa rticipants, or to continue the T rust and distribute benefits as though the Plan had not been terminated.

The Master Trust investments include the Union Pacific Common Stock Fund, which is invested in the common stock of the Corporation. The Corporation is the parent holding company of the Plan sponsor and, therefore, these transactions qualify as party-in-interest transactions. At December 31, 2015 and 2014 , the Plan’s interest in the Master Trust’s investment in the Union Pacific Common Stock Fund had a cost basis of $ 120,800,291 and $ 113,932,567 , respectively. During the years ended December 31, 2015 and 2014 , the Plan record ed dividend income of $6,661,972 and $ 6,043,484 , respectively.

The Master Trust also invests in various funds managed by VFTC. VFTC is the trustee as defined by the Plan and, therefore, the related transactions qualify as party-in-interest transactions.

In 201 4 , there was inadvertent use of Plan assets by the Company , a related party, due to administrative errors which violated IRC Section 4975(c)(1)(B) . Participant withholdings of $ 17 were not timely deposited with the Plan trustee. Therefore, the transactions constituted an extension of credit from the Plan to the Company . The Company repaid the withholdings and lost earnings in 2014 and 2015.

A reconciliation of changes in net assets available for benefits per the financial statements to the Form 5500 as of December 31, 2015 and 2014 , is as follows:
