Total net FAS/CAS pension adjustments, including the service and non-service cost components of FAS pension expense, were as follows (in millions):
## Table 0 ##
(a) We record the non-service cost components of net periodic benefit cost as part of other non-operating expense, net in the consolidated statement of earnings.
The non-service cost components in the table above relate only to our qualified defined benefit pension plans.
We incurred total non-service costs for our qualified defined benefit pension plans in the table above, along with similar costs for our other postretirement benefit plans of $67 million, $109 million, and $123 million for the years ended 2018, 2017 and 2016.
We recover CAS pension cost through the pricing of our products and services on U. S.  Government contracts and, therefore, recognize CAS pension cost in each of our business segment’s net sales and cost of sales.
Our consolidated financial statements must present FAS pension and other postretirement benefit plan expense calculated in accordance with FAS requirements under U. S.  GAAP.
The operating portion of the net FAS/CAS pension adjustment represents the difference between the service cost component of FAS pension expense and CAS pension cost.
The non-service FAS pension cost component is included in other non-operating expense, net on our consolidated statements of earnings.
The net FAS/CAS pension adjustment increases or decreases CAS pension cost to equal total FAS pension expense (both service and non-service).
The following segment discussions also include information relating to backlog for each segment.
Backlog was approximately $130.5 billion, $105.5 billion and $103.5 billion at December 31, 2018, 2017 and 2016.
These amounts included both funded backlog (firm orders for which funding has been both authorized and appropriated by the customer) and unfunded backlog (firm orders for which funding has not yet been appropriated).
Backlog does not include unexercised options or task orders to be issued under indefinite-delivery, indefinite-quantity contracts.
Funded backlog was approximately $86.4 billion at December 31, 2018.
Management evaluates performance on our contracts by focusing on net sales and operating profit and not by type or amount of operating expense.
Consequently, our discussion of business segment performance focuses on net sales and operating profit, consistent with our approach for managing the business.
This approach is consistent throughout the life cycle of our contracts, as management assesses the bidding of each contract by focusing on net sales and operating profit and monitors performance on our contracts in a similar manner through their completion.
We regularly provide customers with reports of our costs as the contract progresses.
The cost information in the reports is accumulated in a manner specified by the requirements of each contract.
For example, cost data provided to a customer for a product would typically align to the subcomponents of that product (such as a wing-box on an aircraft) and for services would align to the type of work being performed (such as aircraft sustainment).
Our contracts generally allow for the recovery of costs in the pricing of our products and services.
Most of our contracts are bid and negotiated with our customers under circumstances in which we are required to disclose our estimated total costs to provide the product or service.
This approach for negotiating contracts with our U. S.  Government customers generally allows for the recovery of our costs.
We also may enter into long-term supply contracts for certain materials or components to coincide with the production schedule of certain products and to ensure their availability at known unit prices.
Many of our contracts span several years and include highly complex technical requirements.
At the outset of a contract, we identify and monitor risks to the achievement of the technical, schedule and cost aspects of the contract and assess the effects of those risks on our estimates of total costs to complete the contract.
The estimates consider the technical requirements (e. g. , a newlydeveloped product versus a mature product), the schedule and associated tasks (e. g. , the number and type of milestone events) and costs (e. g. , material, labor, subcontractor, overhead and the estimated costs to fulfill our industrial cooperation agreements required under certain contracts with international customers).
The initial profit booking rate of each contract considers risks surrounding the ability to achieve the technical requirements, schedule and costs in the initial estimated total costs to complete the contract.
Profit booking rates may increase during the performance of the contract if we successfully retire risks surrounding
NOTE 15 EMPLOYEE BENEFIT PLANS PENSION AND POSTRETIREMENT PLANS We have a noncontributory, qualified defined benefit pension plan covering eligible employees.
Benefits are determined using a cash balance formula where earnings credits are a percentage of eligible compensation.
Earnings credit percentages for plan participants on December 31, 2009 are frozen at their level earned to that point.
Earnings credits for all employees who become participants on or after January 1, 2010 are a flat 3% of eligible compensation.
Participants at December 31, 2009 earn interest based on 30-year Treasury securities with a minimum rate, while new participants on or after January 1, 2010 are not subject to the minimum rate.
Pension contributions are based on an actuarially determined amount necessary to fund total benefits payable to plan participants.
We also maintain nonqualified supplemental retirement plans for certain employees and provide certain health care and life insurance benefits for qualifying retired employees (postretirement benefits) through various plans.
The nonqualified pension and postretirement benefit plans are unfunded.
The Company reserves the right to terminate plans or make plan changes at any time.
We use a measurement date of December 31 for plan assets and benefit obligations.
A reconciliation of the changes in the projected benefit obligation for qualified pension, nonqualified pension and postretirement benefit plans as well as the change in plan assets for the qualified pension plan follows.
Table 112: Reconciliation of Changes in Projected Benefit Obligation and Change in Plan Assets
## Table 1 ##
To determine stock-based compensation expense, the grant date fair value is applied to the options granted with a reduction for estimated forfeitures.
We recognize compensation expense for stock options on a straight-line basis over the specified vesting period.
At December 31, 2012 and 2011, options for 12,759,000 and 12,337,000 shares of common stock were exercisable at a weighted-average price of $90.86 and $106.08, respectively.
The total intrinsic value of options exercised during 2013, 2012 and 2011 was $86 million, $37 million and $4 million, respectively.
The total tax benefit recognized related to compensation expense on all share-based payment arrangements during 2013, 2012 and 2011 was approximately $56 million, $37 million and $38 million, respectively.
Cash received from option exercises under all Incentive Plans for 2013, 2012 and 2011 was approximately $208 million, $118 million and $41 million, respectively.
The tax benefit realized from option exercises under all Incentive Plans for 2013, 2012 and 2011 was approximately $31 million, $14 million and $1 million, respectively.
Shares of common stock available during the next year for the granting of options and other awards under the Incentive Plans were 24,535,159 at December 31, 2013.
Total shares of PNC common stock authorized for future issuance under equity compensation plans totaled 25,712,719 shares at December 31, 2013, which includes shares available for issuance under the Incentive Plans and the Employee Stock Purchase Plan (ESPP) as described below.
During 2013, we issued approximately 2.6 million shares from treasury stock in connection with stock option exercise activity.
As with past exercise activity, we currently intend to utilize primarily treasury stock for any future stock option exercises.
Awards granted to non-employee directors in 2013, 2012 and 2011 include 27,076, 25,620 and 27,090 deferred stock units, respectively, awarded under the Outside Directors Deferred Stock Unit Plan.
A deferred stock unit is a phantom share of our common stock, which is accounted for as a liability until such awards are paid to the participants in cash.
As there are no vesting or service requirements on these awards, total compensation expense is recognized in full for these awards on the date of grant.
INCENTIVE/PERFORMANCE UNIT SHARE AWARDS AND RESTRICTED STOCK/SHARE UNIT AWARDS The fair value of nonvested incentive/performance unit share awards and restricted stock/share unit awards is initially determined based on prices not less than the market value of our common stock on the date of grant.
The value of certain incentive/performance unit share awards is subsequently remeasured based on the achievement of one or more financial and other performance goals, generally over a three-year period.
The Personnel and Compensation Committee (“P&CC”) of the Board of Directors approves the final award payout with respect to certain incentive/performance unit share awards.
Restricted stock/share unit awards have various vesting periods generally ranging from 3 years to 5 years.
Beginning in 2013, we incorporated several enhanced riskrelated performance changes to certain long-term incentive compensation programs.
In addition to achieving certain financial performance metrics on both an absolute basis and relative to our peers, final payout amounts will be subject to reduction if PNC fails to meet certain risk-related performance metrics as specified in the award agreement.
However, the P&CC has the discretion to waive any or all of this reduction under certain circumstances.
These awards have either a threeyear or a four-year performance period and are payable in either stock or a combination of stock and cash.
Additionally, performance-based restricted share units were granted in 2013 to certain executives as part of annual bonus deferral criteria.
These units, payable solely in stock, vest ratably over a four-year period and contain the same riskrelated discretionary criteria noted in the preceding paragraph.
The weighted-average grant date fair value of incentive/ performance unit share awards and restricted stock/unit awards granted in 2013, 2012 and 2011 was $64.77, $60.68 and $63.25 per share, respectively.
The total fair value of incentive/performance unit share and restricted stock/unit awards vested during 2013, 2012 and 2011 was approximately $63 million, $55 million and $52 million, respectively.
We recognize compensation expense for such awards ratably over the corresponding vesting and/or performance periods for each type of program.
