Baker Hughes, a GE company Notes to Consolidated and Combined Financial Statements In 2018, the total intrinsic value of RSUs vested (defined as the market value of shares awarded at vesting date) was $41 million and unvested RSUs was $148 million.
The total fair value of RSUs vested in 2018 was $45 million.
As of December 31, 2018, there was $166 million of total unrecognized compensation cost related to unvested RSUs, which is expected to be recognized over a weighted average period of 1.9 years.
Performance Share Units During 2018, we initiated a new plan where we grant performance share units (PSUs) to certain officers and key employees.
The PSUs are stock-based awards tied to predefined company metrics which determine the number of units to be received.
PSUs generally cliff vest after a three-year service period.
Cash dividend equivalents are accrued on PSUs and are payable upon vesting of the awards.
The fair value of the awards are based on the market price of our common stock on the date of grant.
During 2018, we granted 952 thousand PSUs at a weighted average grant date fair value of $35.13.
At December 31, 2018, we had 927 thousand PSUs unvested and outstanding.
The total intrinsic value of PSUs (defined as the value of the shares awarded at the year end market price) outstanding was $20 million as of December 31, 2018.
Total unrecognized compensation cost related to unvested PSUs, which is expected to be recognized over a weighted average period of 2.2 years, was $23 million as of December 31, 2018.
NOTE 14.
EQUITY COMMON STOCK We are authorized to issue 2 billion shares of Class A common stock, 1.25 billion shares of Class B common stock and 50 million shares of preferred stock each of which have a par value of $0.0001 per share.
The number of shares of Class A common stock and Class B common stock outstanding at December 31, 2018 is 513 million and 522 million, respectively.
We have not issued any preferred stock.
GE owns all the issued and outstanding Class B common stock.
Each share of Class A and Class B common stock and the associated membership interest in BHGE LLC form a paired interest.
While each share of Class B common stock has equal voting rights to a share of Class A common stock, it has no economic rights, meaning holders of Class B common stock have no right to dividends and any assets in the event of liquidation of the Company.
During 2018 and 2017, the Company declared and paid aggregate regular dividends of $0.72 per share and $0.35 per share, respectively, to holders of record of the Company's Class A common stock.
In addition, in 2017 former Baker Hughes stockholders, immediately after the completion of the Transactions, received a special onetime cash dividend of $17.50 per share paid by the Company to holders of record of the Company's Class A common stock.
The following table presents the changes in the number of shares outstanding (in thousands):

Year Ended December 31,
## Table 2 ##
(1) Inventory impairments and related charges are reported in the "Cost of goods sold" caption of the consolidated and combined statements of income (loss).2017 includes $87 million of adjustments to write-up the acquired inventory to its estimated fair value on acquisition of Baker Hughes as this inventory was used or sold in the six months ended December 31, 2017.
Fiscal Year 2018 to Fiscal Year 2017 Revenue in 2018 was $22,877 million, an increase of $5,698 million, or 33%, from 2017.
This increase in revenue was largely a result of the incremental Baker Hughes revenue in 2018.
OFS increased $5,736 million, DS increased $262 million, OFE decreased $20 million, and TPS decreased $280 million.
Total segment operating income in 2018 was $1,796 million, an increase of $681 million, or 61%, from 2017.
The increase was primarily driven by OFS, which increased $718 million, and DS, which increased $33 million, partially offset by TPS, which decreased $44 million, and OFE, which decreased $26 million.
INTEREST RATE RISK All of our long-term debt is comprised of fixed rate instruments.
We are subject to interest rate risk on our debt and investment portfolio.
We may use interest rate swaps to manage the economic effect of fixed rate obligations associated with certain debt.
There were no outstanding interest rate swap agreements as of December 31, 2018.
The following table sets forth our fixed rate long-term debt, excluding capital leases, and the related weighted average interest rates by expected maturity dates.
## Table 3 ##
(1) Fair market value of our fixed rate long-term debt, excluding capital leases, was $5.6 billion at December 31, 2018.
(2) Amounts represent the principal value of our long-term debt outstanding and related weighted average interest rates at the end of the respective period.
FOREIGN CURRENCY EXCHANGE RISK We conduct our operations around the world in a number of different currencies, and we are exposed to market risks resulting from fluctuations in foreign currency exchange rates.
Many of our significant foreign subsidiaries have designated the local currency as their functional currency.
As such, future earnings are subject to change due to fluctuations in foreign currency exchange rates when transactions are denominated in currencies other than our functional currencies.
Additionally, we buy, manufacture and sell components and products across global markets.
These activities expose us to changes in foreign currency exchange rates, commodity prices and interest rates which can adversely affect revenue earned and costs of our operating businesses.
When the currency in which equipment is sold differs from the primary currency of the legal entity and the exchange rate fluctuates, it will affect the revenue earned on the sale.
These sales and purchase transactions also create receivables and payables denominated in foreign currencies and exposure to foreign currency gains and losses based on changes in exchange rates.
Changes in the price of raw materials used in manufacturing can affect the cost of manufacturing.
We use derivatives to mitigate or eliminate these exposures, where appropriate.
We use cash flow hedging primarily to reduce or eliminate the effects of foreign currency exchange rate changes on purchase and sale contracts.
Accordingly, most derivative activity in this category consists of currency exchange contracts.
We had outstanding foreign currency forward contracts with net notional amounts aggregating $2.8 billion and $3.3 billion to hedge exposure to currency fluctuations in various foreign currencies at December 31, 2018 and 2017, respectively.
As of December 31, 2018, the Company estimates that a 1% appreciation or depreciation in the U. S.  dollar would result in an impact of less than $5 million to our pre-tax earnings, however, the Company is generally able to mitigate its foreign exchange exposure, where there are liquid financial markets, through use of foreign currency derivative transactions.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS Union Pacific Corporation and Subsidiary Companies For purposes of this report, unless the context otherwise requires, all references herein to the “Corporation”, “UPC”, “we”, “us”, and “our” mean Union Pacific Corporation and its subsidiaries, including Union Pacific Railroad Company, which will be separately referred to herein as “UPRR” or the “Railroad”.1.
Nature of Operations Operations and Segmentation – We are a Class I railroad operating in the U. S.  Our network includes 31,868 route miles, linking Pacific Coast and Gulf Coast ports with the Midwest and eastern U. S.  gateways and providing several corridors to key Mexican gateways.
We own 26,020 miles and operate on the remainder pursuant to trackage rights or leases.
We serve the western two-thirds of the country and maintain coordinated schedules with other rail carriers for the handling of freight to and from the Atlantic Coast, the Pacific Coast, the Southeast, the Southwest, Canada, and Mexico.
Export and import traffic is moved through Gulf Coast and Pacific Coast ports and across the Mexican and Canadian borders.
The Railroad, along with its subsidiaries and rail affiliates, is our one reportable operating segment.
Although we provide and review revenue by commodity group, we analyze the net financial results of the Railroad as one segment due to the integrated nature of our rail network.
The following table provides freight revenue by commodity group:
## Table 4 ##
Although our revenues are principally derived from customers domiciled in the U. S. , the ultimate points of origination or destination for some products transported by us are outside the U. S.  Each of our commodity groups includes revenue from shipments to and from Mexico.
Included in the above table are revenues from our Mexico business which amounted to $1.9 billion in 2012, $1.8 billion in 2011, and $1.6 billion in 2010.

Significant Accounting Policies Principles of Consolidation – The Consolidated Financial Statements include the accounts of Union Pacific Corporation and all of its subsidiaries.
Investments in affiliated companies (20% to 50% owned) are accounted for using the equity method of accounting.
All intercompany transactions are eliminated.
We currently have no less than majority-owned investments that require consolidation under variable interest entity requirements.
Cash and Cash Equivalents – Cash equivalents consist of investments with original maturities of three months or less.
Accounts Receivable – Accounts receivable includes receivables reduced by an allowance for doubtful accounts.
The allowance is based upon historical losses, credit worthiness of customers, and current economic conditions.
Receivables not expected to be collected in one year and the associated allowances are classified as other assets in our Consolidated Statements of Financial Position.
