(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 2017 to Fiscal Year 2016 Revenue in 2017 was $17,259 million, an increase of $3,990 million, or 30%, from 2016.
This increase was primarily driven by the acquisition of Baker Hughes.
OFS increased $5,052 million, DS increased $223 million, OFE decreased $910 million, and TPS decreased $374 million.
Total segment operating income in 2017 was $1,295 million, a decrease of $431 million, or 25%, from 2016.
The acquisition of Baker Hughes added $309 million of segment operating income, but was more than offset by the organic impact of lower productivity and pricing pressure.
OFS increased $275 million, TPS decreased $402 million, OFE decreased $282 million and DS decreased $22 million.
Oilfield Services OFS 2017 revenue was $5,851 million, an increase of $5,052 million from 2016, primarily as a result of the acquisition of Baker Hughes on July 3, 2017.
OFS 2017 segment operating income was $71 million, compared to a loss of $204 million in 2016.
The acquisition of Baker Hughes added $315 million of segment operating income, which includes increased depreciation & amortization expense driven by purchase accounting, partially offset by pricing pressure.
Oilfield Equipment OFE 2017 revenue was $2,637 million, a decrease of $910 million, or 26%, from 2016.
The revenue decline was primarily due to continued volume pressures and to a lesser extent to negative pricing, driven by the delays in final investment decisions by our customers in prior years.
LIQUIDITY AND CAPITAL RESOURCES Our objective in financing our business is to maintain sufficient liquidity, adequate financial resources and financial flexibility in order to fund the requirements of our business.
At December 31, 2017, we had cash and equivalents of $7.0 billion compared to $981 million of cash and equivalents at December 31, 2016.
Cash and equivalents includes $997 million of cash held on behalf of GE at December 31, 2017.
At December 31, 2017, approximately $3.2 billion of our cash and equivalents was held by foreign subsidiaries compared to approximately $878 million at December 31, 2016.
A substantial portion of the cash held by foreign subsidiaries at December 31, 2017 has been reinvested in active non-U.
S.  business operations.
At December 31, 2017, our intent is, among other things, to use this cash to fund the operations of our foreign subsidiaries, and we have not changed our indefinite reinvestment decision as a result of U. S.  tax reform but will reassess this during the course of 2018.
If we decide at a later date to repatriate those funds to the U. S. , we may be required to provide taxes on certain of those funds, however, due to the enactment of U. S.  tax reform, repatriations of foreign earnings will generally be free of U. S.  federal tax but may incur other taxes such as withholding or state taxes.
On July 3, 2017, in connection with the Transactions, BHGE LLC entered into a new five-year $3 billion committed unsecured revolving credit facility (2017 Credit Agreement) with commercial banks maturing in July 2022.

At December 31, 2017, there were no borrowings outstanding under the commercial paper program.
The maximum combined borrowing at any time under both the 2017 Credit Agreement and the commercial paper program is $3 billion.
On November 6, 2017, we announced that our board of directors authorized BHGE LLC to repurchase up to $3 billion of its common units from the Company and GE.
The proceeds of such repurchase that are distributed to the Company will be used to repurchase Class A shares of the Company on the open market or in privately negotiated transactions.
On December 15, 2017, we filed a shelf registration statement on Form S-3 with the SEC to give us the ability to sell up to $3 billion in debt securities in amounts to be determined at the time of an offering.
Any such offering, if it does occur, may happen in one or more transactions.
The specific terms of any securities to be sold will be described in supplemental filings with the SEC.
The registration statement will expire in 2020.
During the year ended December 31, 2017, we used cash to fund a variety of activities including certain working capital needs and restructuring costs, capital expenditures, business acquisitions, the payment of dividends and share repurchases.
We believe that cash on hand, cash flows generated from operations and the available credit facility will provide sufficient liquidity to manage our global cash needs.
Cash Flows Cash flows provided by (used in) each type of activity were as follows for the years ended December 31:

ITEM 7A.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to certain market risks that are inherent in our financial instruments and arise from changes in interest rates and foreign currency exchange rates.
We may enter into derivative financial instrument transactions to manage or reduce market risk but do not enter into derivative financial instrument transactions for speculative purposes.
A discussion of our primary market risk exposure in financial instruments is presented below.
INTEREST RATE RISK The majority of our 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, 2017.
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 2 ##
(1) Fair market value of our fixed rate long-term debt, excluding capital leases, was $7.0 billion at December 31, 2017.
