Impaired Loans Impaired loans include commercial and consumer nonperforming loans and TDRs, regardless of nonperforming status.
TDRs that were previously recorded at amortized cost and are now classified and accounted for as held for sale are also included.
Excluded from impaired loans are nonperforming leases, loans accounted for as held for sale other than the TDRs described in the preceding sentence, loans accounted for under the fair value option, smaller balance homogeneous type loans and purchased impaired loans.
We did not recognize any interest income on impaired loans that have not returned to performing status, while they were impaired during the year ended December 31, 2016 and December 31, 2015.
The following table provides further detail on impaired loans individually evaluated for impairment and the associated ALLL.
Certain commercial and consumer impaired loans do not have a related ALLL as the valuation of these impaired loans exceeded the recorded investment.
Table 43: Impaired Loans
## Table 0 ##
(a) Average recorded investment is for the years ended December 31, 2016 and 2015.
NOTE 4 ALLOWANCES FOR LOAN AND LEASE LOSSES We maintain the ALLL at levels that we believe to be appropriate to absorb estimated probable credit losses incurred in the portfolios as of the balance sheet date.
We use the two main portfolio segments – Commercial Lending and Consumer Lending, and develop and document the ALLL under separate methodologies for each of these portfolio segments.
See Note 1 Accounting Policies for a description of the accounting policies for ALLL.
A rollforward of the ALLL and associated loan data follows.
The expected return on plan assets is a long-term assumption established by considering historical and anticipated returns of the asset classes invested in by the pension plan and the allocation strategy currently in place among those classes.
For purposes of setting and reviewing this assumption, “long term” refers to the period over which the plan’s projected benefit obligations will be disbursed.
We review this assumption at each measurement date and adjust it if warranted.
Our selection process references certain historical data and the current environment, but primarily utilizes qualitative judgment regarding future return expectations.
We also examine the assumption used by other companies with similar pension investment strategies.
Taking into account all of these factors, the expected long-term return on plan assets for determining net periodic pension cost for 2016 was 6.75%.
We are reducing our expected long-term return on assets to 6.375% for determining pension cost for 2017.
This decision was made after considering the views of both internal and external capital market advisors, particularly with regard to the effects of the recent economic environment on long-term prospective equity and fixed income returns.
PNC’s net periodic benefit cost recognized for the plans is sensitive to the discount rate and expected long-term return on plan assets.
With all other assumptions held constant, a .5% decline in the discount rate would have resulted in an immaterial increase in net periodic benefit cost for the qualified pension plan in 2016, and to be recognized in 2017.
For the nonqualified pension plan and postretirement benefits, a .5% decline in the discount rate would also have resulted in an immaterial increase in net periodic benefit cost.
The health care cost trend rate assumptions shown in Tables 75 and 76 relate only to the postretirement benefit plans.
The effect of a one-percentage-point increase or decrease in assumed health care cost trend rates would be insignificant.
Defined Contribution Plans The PNC Incentive Savings Plan (ISP) is a qualified defined contribution plan that covers all of our eligible employees.
Effective January 1, 2015, newly-hired full time employees and part-time employees who became eligible to participate in the ISP after that date are automatically enrolled in the ISP with a deferral rate equal to 4% of eligible compensation in the absence of an affirmative election otherwise.
Employee benefits expense related to the ISP was $.1 billion in 2016, 2015 and 2014, representing cash contributed to the ISP by PNC.
The ISP is a 401(k) Plan and includes an employee stock ownership (ESOP) feature.
Employee contributions are invested in a number of investment options, including pre mixed portfolios and individual core funds, available under the ISP at the direction of the employee.
NOTE 12 STOCK BASED COMPENSATION PLANS We have long-term incentive award plans (Incentive Plans) that provide for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, incentive shares/performance units, restricted shares, restricted share units, other share-based awards and dollar-denominated awards to executives and, other than incentive stock options, to non-employee directors.
Certain Incentive Plan awards may be paid in stock, cash or a combination of stock and cash.
We typically grant a substantial portion of our stock-based compensation awards during the first quarter of each year.
Total compensation expense recognized related to all sharebased payment arrangements was approximately $.2 billion during each of 2016, 2015 and 2014.
The total tax benefit recognized related to compensation expense on all share-based payment arrangements was approximately $.1 billion during each of 2016, 2015 and 2014.
At December 31, 2016, there was $.2 billion of unamortized share-based compensation expense related to nonvested equity compensation arrangements granted under the Incentive Plans.
This unamortized cost is expected to be recognized as expense over a period of no longer than five years.
Nonqualified Stock Options We did not grant any stock options in 2016, 2015 or 2014.
Prior to 2014, options were granted at exercise prices not less than the market value of a share of common stock on the grant date.
Generally, options become exercisable in installments after the grant date.
No option can be exercised after 10 years from its grant date.
Payment of the option exercise price may be in cash or by surrendering shares of common stock at market value on the exercise date.
The exercise price may also be paid by using previously owned shares.
The following table represents the stock option activity for 2016.
Table 77: Stock Options – Rollforward (a)
## Table 1 ##
(a) Cancelled stock options during 2016 were insignificant.
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.
PART II ITEM 5 – MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES (a) (1) Our common stock is listed on the New York Stock Exchange and is traded under the symbol “PNC.
” At the close of business on February 16, 2017, there were 60,763 common shareholders of record.
Holders of PNC common stock are entitled to receive dividends when declared by the Board of Directors out of funds legally available for this purpose.
Our Board of Directors may not pay or set apart dividends on the common stock until dividends for all past dividend periods on any series of outstanding preferred stock and certain outstanding capital securities issued by the parent company have been paid or declared and set apart for payment.
The Board of Directors presently intends to continue the policy of paying quarterly cash dividends.
The amount of any future dividends will depend on economic and market conditions, our financial condition and operating results, and other factors, including contractual restrictions and applicable government regulations and policies (such as those relating to the ability of bank and non-bank subsidiaries to pay dividends to the parent company and regulatory capital limitations).
The amount of our dividend is also currently subject to the results of the supervisory assessment of capital adequacy and capital planning processes undertaken by the Federal Reserve and our primary bank regulators as part of the Comprehensive Capital Analysis and Review (CCAR) process as described in the Supervision and Regulation section in Item 1 of this Report.
The Federal Reserve has the power to prohibit us from paying dividends without its approval.
For further information concerning dividend restrictions and other factors that could limit our ability to pay dividends, as well as restrictions on loans, dividends or advances from bank subsidiaries to the parent company, see the Supervision and Regulation section in Item 1, Item 1A Risk Factors, the Capital and Liquidity Management portion of the Risk Management section in Item 7, and Note 10 Borrowed Funds, Note 15 Equity and Note 18 Regulatory Matters in the Notes To Consolidated Financial Statements in Item 8 of this Report, which we include here by reference.

(b) On March 11, 2015, we announced that our Board of Directors approved the establishment of a stock repurchase program authorization in the amount of 100 million shares of PNC common stock, effective April 1, 2015.
Repurchases are made in open market or privately negotiated transactions and the timing and exact amount of common stock repurchases will depend on a number of factors including, among others, market and general economic conditions, regulatory capital considerations, alternative uses of capital, the potential impact on our credit ratings, and contractual and regulatory limitations, including the results of the supervisory assessment of capital adequacy and capital planning processes undertaken by the Federal Reserve as part of the CCAR process.
In June 2016, we announced share repurchase programs of up to $2.0 billion for the four quarter period beginning with the third quarter of 2016, including repurchases of up to $200 million related to employee benefit plans.
In January 2017, we announced a $300 million increase in our share repurchase programs for this period.
In the fourth quarter of 2016, we repurchased 4.9 million shares of common stock on the open market, with an average price of $101.47 per share and an aggregate repurchase price of $.5 billion.
See the Liquidity and Capital Management portion of the Risk Management section in Item 7 of this Report for more information on the share repurchase programs under the share repurchase authorization for the period July 1, 2016 through June 30, 2017 included in the 2016 capital plan accepted by the Federal Reserve.
