are reclassified to contributions in aid of construction.
Utility plant funded by advances and contributions is excluded from the rate base.
Generally, we depreciate contributed property and amortize contributions in aid of construction at the composite rate of the related property.
Some of our subsidiaries do not depreciate contributed property, based on regulatory guidelines.
We use our capital resources, including cash, primarily to; (i) fund operating and capital requirements; (ii) pay interest and meet debt maturities; (iii) pay dividends; (iv) fund pension and postretirement welfare obligations; and (v) fund acquisitions.
We invest a significant amount of cash on regulated capital projects where we expect to earn a long-term return on investment.
Additionally, we operate in rate-regulated environments in which the amount of new investment recovery may be limited, and where such recovery takes place over an extended period of time, as our recovery is subject to regulatory lag.
See Item 1—Business—Operating Segments—Regulated Businesses—Economic Regulation and Rate Making Process.
We expect to fund future maturities of long-term debt through a combination of external debt and, to the extent available, cash flows from operations.
Since we expect our capital investments over the next few years to be greater than or equal to our cash flows from operating activities, we have no plans to reduce debt significantly.
If necessary, the Company may delay certain capital investments or other funding requirements or pursue financing from other sources to preserve liquidity, if necessary.
In this event, we believe we can rely upon cash flows from operations to meet our obligations and fund our minimum required capital investments for an extended period of time.
Cash Flows Provided by Operating Activities Cash flows provided by operating activities primarily result from the sale of water and wastewater services and, due to the seasonality of demand, are generally greater during the third quarter of each fiscal year.
Our future cash flows provided by operating activities will be affected by, among other things, economic utility regulation; infrastructure investment; inflation; compliance with environmental, health and safety standards; production costs; customer growth; declining customer usage of water; employee-related costs, including pension funding; weather and seasonality; and overall economic conditions.
Cash flows provided by operating activities have been a reliable, steady source of funding, sufficient to meet operating requirements, make our dividend payments and fund a portion of our capital expenditure requirements.
We expect to seek access to debt capital markets to meet the balance of our capital expenditure requirements as needed.
We also have access to equity capital markets, if needed.
Operating cash flows can be negatively affected by changes in our rate regulated environments or changes in our customers’ economic outlook and ability to pay for service in a timely manner.
As such, our working capital needs are primarily limited to funding increases in customer accounts receivable and unbilled revenues mainly associated with revenue increases in our Regulated Businesses.
We can provide no assurance that our customers’ historical payment pattern will continue in the future.
We address cash timing differences through the liquidity funding mechanisms discussed above.
The following table provides a summary of the major items affecting our cash flows provided by operating activities:

Baker Hughes, a GE company Notes to Consolidated and Combined Financial Statements
## Table 1 ##
The allocation of net loss to holders of shares of Class A common stock began following the close of the Transactions on July 3, 2017.
Therefore, the earnings per share is Nil for 2016 and 2015.
Please refer to "Note 2.  Business Acquisition" for proforma earnings per share.
As of July 3, 2017, GE, BHGE and BHGE LLC entered into an Exchange Agreement under which GE is entitled to exchange its holding in Class B common stock and units of BHGE LLC for Class A common stock on a one-forone basis (subject to adjustment in accordance with the terms of the Exchange Agreement) or, at the option of BHGE, an amount of cash equal to the aggregate value of the shares of Class A common stock that would have otherwise been received by GE in the exchange.
In computing the dilutive effect, if any, that the aforementioned exchange would have on net income (loss) per share, net income (loss) attributable to holders of Class A common stock would be adjusted due to the elimination of the noncontrolling interests associated with the Class B common stock (including any tax impact).
For the year ended December 31, 2017, such exchange is not reflected in diluted net income (loss) per share as the assumed exchange is not dilutive.
For the year ended December 31, 2017, we excluded outstanding stock options and RSUs from the computation of diluted net income (loss) per share because their effect is antidilutive.
Shares of our Class B common stock do not share in earnings or losses of the Company and are not considered in the calculation of basic or diluted earnings per share (EPS).
As such, separate presentation of basic and diluted EPS of Class B under the two class method has not been presented.

The primary objectives of this interpretation, as amended, are to provide guidance on the identification and consolidation of variable interest entities, or VIEs, which are entities for which control is achieved through means other than through voting rights.
The Company has completed an analysis of this Interpretation and has determined that it does not have any VIEs.4.

## Table 4 ##
A summary of the fair values of retained subordinated interests resulting from the Company’s residential mortgage loan securitization activities follows.
Although the estimated fair values of the retained subordinated interests were obtained from independent pricing sources, the Company has modeled the sensitivity of such fair values to changes in certain assumptions as summarized in the table below.
These calculated sensitivities are hypothetical and actual changes in the fair value may differ significantly from the amounts presented herein.
The effect of a variation in a particular assumption on the fair values is calculated without changing any other assumption.
In reality, changes in one factor may result in changes in another which may magnify or counteract the sensitivities.
The changes in assumptions are presumed to be instantaneous.
The hypothetical effect of adverse changes on the Company’s retained capitalized servicing assets at December 31, 2006 is included in note 7.
