The net periodic benefit cost recognized each year included the following (in millions):
## Table 0 ##
(a) Total net periodic benefit cost associated with our qualified defined benefit plans represents pension expense calculated in accordance with GAAP (FAS pension expense).
We are required to calculate pension expense in accordance with both GAAP and CAS rules, each of which results in a different calculated amount of pension expense.
The CAS pension cost is recovered through the pricing of our products and services on U. S.  Government contracts and, therefore, is recognized in net sales and cost of sales for products and services.
We include the difference between FAS pension expense and CAS pension cost, referred to as the FAS/CAS pension adjustment, as a component of other unallocated, net on our Statements of Earnings.
The FAS/CAS pension adjustment, which was income of $471 million in 2015; income of $376 million in 2014; and expense of $482 million in 2013, effectively adjusts the amount of CAS pension cost in the business segment operating profit so that pension expense recorded on our Statements of Earnings is equal to FAS pension expense.
The following table provides a reconciliation of benefit obligations, plan assets and unfunded status related to our qualified defined benefit pension plans and our retiree medical and life insurance plans (in millions):
## Table 1 ##
(a) Benefits paid in 2014 for qualified defined benefit pension plans include $427 million in the form of lump-sum settlement payments to former employees who had not commenced receiving their vested benefit payments.
The corresponding benefit obligation that was released was $529 million.
The settlement payments had no impact on our 2014 FAS pension expense and CAS pension cost.
(b) The June 2014 plan amendment which resulted in freezing the pay-based component of the formula used to determine retirement benefits under the affected plans reduced our qualified defined benefit pension obligations by $4.6 billion, which resulted in a corresponding reduction, net of tax, in the accumulated other comprehensive loss (AOCL) component of stockholders’ equity.
This amount is being recognized as a reduction of net periodic benefit cost (i. e. , amortization of net prior service credit) over the estimated remaining service period of the covered employees, which is approximately 10 years and began in the third quarter of 2014.
The November 2015 acquisition of Sikorsky increased our qualified defined benefit pension obligations by about $30 million.
The following table provides a summary of our cash flow information followed by a discussion of the key elements (in millions):
## Table 2 ##
Operating Activities 2015 compared to 2014 Net cash provided by operating activities increased $1.2 billion in 2015 compared to 2014 primarily due to lower pension contributions, partially offset by decreases in working capital and higher tax payments.
The $1.8 billion increase in cash flows related to Other, net in the table above is primarily because we made no contributions to our heritage qualified defined benefit pension trust in 2015 compared to $2.0 billion in 2014.
We made $5.0 million in contributions to our new Sikorsky bargained qualified defined benefit pension plan in 2015.
The increase in cash flows related to Other, net was offset by higher federal and foreign income tax payments, net of refunds received, of approximately $210 million in 2015 compared to 2014 due primarily to the absence of refunds received in 2015 (prior year’s tax refunds were attributable to timing of discretionary pension contributions made during the fourth quarter of the respective previous years).
The $474 million decrease in cash flows related to working capital (defined as receivables and inventories less accounts payable and customer advances and amounts in excess of costs incurred) was attributable to an increase in receivables due to timing of customer collections (primarily F-35 contracts) as well as timing of production and billing cycles affecting customer advances and progress payments applied to inventories (primarily C-130 program).
See “Critical Accounting Policies – Postretirement Benefit Plans” (under the caption “Funding Considerations”) for discussion of future postretirement benefit plan funding.2014 compared to 2013 Net cash provided by operating activities decreased $680 million in 2014 compared to 2013 primarily due to higher tax payments, net of refunds received and increases in working capital.
Our federal and foreign income tax payments, net of refunds received, were approximately $760 million higher in 2014 compared to 2013 due to an increase in net income and lower refunds received in 2014 (attributable to timing of discretionary pension contributions made during the fourth quarter of 2012).
The decrease of $274 million in cash provided by working capital (defined as receivables and inventories less accounts payable and customer advances and amounts in excess of costs incurred) was primarily attributable to lower cash receipts related to accounts receivable, primarily timing on the F-35 production contracts (including amounts received in 2013 from resolving U. S.  Government contractual withholds that were not repeated in 2014).
Partially offsetting the decreases in operating cash flows were lower pension contributions in 2014.
We made $2.0 billion in contributions to our qualified defined benefit pension plans in 2014, compared to $2.25 billion in 2013.
Investing Activities Net cash used for investing activities increased $8.0 billion and $602 million in 2015 and 2014, respectively, compared to the prior year, primarily due to increased acquisition activities.
Acquisition activities include both the acquisition of businesses and investments in affiliates.
We paid $9.0 billion in 2015 for the Sikorsky acquisition, net of cash acquired (Note 3).
We paid $898 million in 2014 for acquisition activities, primarily related to the acquisitions of Zeta, Systems Made Simple, and Industrial Defender.
In 2013, we paid $269 million for acquisition activities, primarily related to the acquisition of Amor Group.
The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):
## Table 3 ##
(a) Recorded in Other noncurrent liabilities on the consolidated balance sheet.
Intangible assets related to customer programs were recognized for each major helicopter and aftermarket program and represent the aggregate value associated with the customer relationships, contracts, technology and tradenames underlying the associated program.
These intangible assets will be amortized over a weighted-average useful life of approximately 15 years in accordance with the underlying pattern of economic benefit as reflected by the future net cash inflows.
Customer contractual obligations represent liabilities on certain development programs where the expected costs exceed the expected sales under contract.
We measured these liabilities based on the price to transfer the obligation to a market participant at the measurement date, assuming that the liability will remain outstanding in the marketplace.
Based on the estimated net cash outflows of the developmental programs plus a reasonable contracting profit margin required to transfer the contracts to market participants, we recorded assumed liabilities of approximately $480 million.
These liabilities will be liquidated in accordance with the underlying economic pattern of the contractual obligations, as reflected by the estimated future net cash outflows incurred on the associated contracts.
Estimated liquidation of the contractual obligation is estimated is as follows: $85 million in 2016, $90 million in 2017, $65 million in 2018, $60 million in 2019, $60 million in 2020 and $110 million thereafter.
The fair values of the assets acquired and liabilities assumed were preliminarily determined using income, market and cost valuation methodologies.
The fair value measurements were estimated using significant inputs that are not observable in the market and thus represent a Level 3 measurement as defined in Accounting Standards Codification (ASC) 820.
The income approach was primarily used to value the customer programs and trademarks intangible assets.
The income approach indicates value for an asset or liability based on the present value of cash flow projected to be generated over the remaining economic life of the asset or liability being measured.
Both the amount and the duration of the cash flows are considered from a market participant perspective.
Our estimates of market participant net cash flows considered historical and projected pricing, remaining developmental effort, operational performance including company specific synergies, aftermarket retention, product life cycles, material and labor pricing, and other relevant customer, contractual and market factors.
Where appropriate, the net cash flows are adjusted to reflect the uncertainties associated with the underlying assumptions, as well as the risk profile of the net cash flows utilized in the valuation.
The adjusted future cash flows are then discounted to present
MANAGEMENT’S DISCUSSION AND ANALYSISOF FINANCIAL CONDITION AND RESULTS OF OPERATIONS In 2008, ASP was flat compared to 2007.
By comparison, ASP decreased approximately 9% in 2007 anddecreased approximately 11% in 2006.
The segment has several large customers located throughout the world.
In 2008, aggregate net sales to thesegment’s five largest customers accounted for approximately 41% of the segment’s net sales.
Besides sellingdirectly to carriers and operators, the segment also sells products through a variety of third-party distributors andretailers, which accounted for approximately 24% of the segment’s net sales in 2008.
Although the U. S.  market continued to be the segment’s largest individual market, many of our customers,and 56% of the segment’s 2008 net sales, were outside the U. S.  In 2008, the largest of these internationalmarkets were Brazil, China and Mexico.
As the segment’s revenue transactions are largely denominated in local currencies, we are impacted by theweakening in the value of these local currencies against the U. S.  dollar.
A number of our more significantinternational markets, particularly in Latin America, were impacted by this trend in late 2008.
Home and Networks Mobility SegmentThe Home and Networks Mobility segment designs, manufactures, sells, installs and services: (i) digitalvideo, Internet Protocol video and broadcast network interactive set-tops, end-to-end video distribution systems,broadband access infrastructure platforms, and associated data and voice customer premise equipment to cabletelevision and telecom service providers (collectively, referred to as the ‘‘home business’’), and (ii) wireless accesssystems, including cellular infrastructure systems and wireless broadband systems, to wireless service providers(collectively, referred to as the ‘‘network business’’).
In 2009, the segment’s net sales represented 36% of theCompany’s consolidated net sales, compared to 33% in 2008 and 27% in 2007.
