Registration Statements ?
In May 2006, we filed a shelf registration statement on Form S-3 that registered an indeterminate amount of debt securities.
This registration statement was effective immediately upon filing under Securities and Exchange Commission regulations governing “well-known seasoned issuers” (the “WKSI Registration Statement”).  ?
In August 2006, we issued $250 million of 5.3% Notes due September 1, 2011, and $250 million of 5.45% Notes due September 1, 2016.
These Notes were issued under the WKSI Registration Statement.  ?
In March 2008, we issued $250 million of 5.0% Notes due April 1, 2013.
The Notes were issued under the WKSI Registration Statement.  ?
Proceeds from the debt issuances and any other offerings under the WKSI Registration Statement may be used for general corporate requirements.
These may include reducing existing borrowings, financing capital additions, funding contributions to our pension plans, future business acquisitions and working capital requirements.
OFF-BALANCE SHEET ARRANGEMENTS, CONTRACTUAL OBLIGATIONS AND CONTINGENT LIABILITIES AND COMMITMENTS As of December 31, 2008, our contractual cash obligations by year were as follows:
## Table 0 ##
In entering into contractual obligations, we have assumed the risk that might arise from the possible inability of counterparties to meet the terms of their contracts.
We mitigate this risk by performing financial assessments prior to contract execution, conducting periodic evaluations of counterparty performance and maintaining a diverse portfolio of qualified counterparties.
Our risk is limited to replacing the contracts at prevailing market rates.
We do not expect any significant losses resulting from counterparty defaults.
Purchase Obligations We enter into certain obligations for the purchase of raw materials.
These obligations were primarily in the form of forward contracts for the purchase of raw materials from third-party brokers and dealers.
These contracts minimize the effect of future price fluctuations by fixing the price of part or all of these purchase obligations.
Total obligations for each year presented above, consists of fixed price contracts for the purchase of commodities and unpriced contracts that were valued using market prices as of December 31, 2008.
The cost of commodities associated with the unpriced contracts is variable as market prices change over future periods.
We mitigate the variability of these costs to the extent we have entered into commodities futures contracts to hedge our costs for those periods.
Increases or decreases in market prices are offset by gains or losses on commodities futures contracts.
This applies to the extent that we have hedged the unpriced contracts as of December 31, 2008 and in future periods by entering into commodities futures contracts.
Taking delivery of and making payments for the specific commodities for use in the manufacture of finished goods satisfies our obligations under the forward purchase contracts.
For each of the three years in the period ended December 31, 2008, we satisfied these obligations by taking delivery of and making payment for the specific commodities.
On April 3, 2014, consistent with our 2014 capital plan, our Board of Directors approved an increase to PNC’s quarterly common stock dividend from 44 cents per common share to 48 cents per common share beginning with the May 5, 2014 dividend payment.
In connection with the 2015 CCAR, PNC submitted its 2015 capital plan, as approved by its Board of Directors, to the Federal Reserve in January 2015.
PNC expects to receive the Federal Reserve’s response (either a non-objection or objection) to the capital plan submitted as part of the 2015 CCAR in March 2015.
See the Supervision and Regulation section in Item 1 of this Report for additional information regarding the Federal Reserve’s CCAR process and the factors the Federal Reserve takes into consideration in evaluating capital plans, qualitative and quantitative liquidity risk management standards proposed by the U. S.  banking agencies, and final rules issued by the Federal Reserve that make certain modifications to the Federal Reserve’s capital planning and stress testing rules.
See Table 42 for information on affiliate purchases of notes issued by PNC Bank during 2014.
On February 6, 2015, PNC used $600 million of parent company/non-bank subsidiary cash to purchase floating rate senior notes that were issued by PNC Bank to an affiliate on that same date.
Parent Company Liquidity – Sources The principal source of parent company liquidity is the dividends it receives from its subsidiary bank, which may be impacted by the following: ?
Bank-level capital needs, ?
Laws and regulations, ?
Corporate policies, ?
Contractual restrictions, and ?
Other factors.
There are statutory and regulatory limitations on the ability of national banks to pay dividends or make other capital distributions or to extend credit to the parent company or its non-bank subsidiaries.
The amount available for dividend payments by PNC Bank to the parent company without prior regulatory approval was approximately $1.5 billion at December 31, 2014.
See Note 20 Regulatory Matters in the Notes To Consolidated Financial Statements in Item 8 of this Report for a further discussion of these limitations.
We provide additional information on certain contractual restrictions in Note 12 Capital Securities of a Subsidiary Trust and Perpetual Trust Securities in the Notes To Consolidated Financial Statements in Item 8 of this Report.
In addition to dividends from PNC Bank, other sources of parent company liquidity include cash and investments, as well as dividends and loan repayments from other subsidiaries and dividends or distributions from equity investments.
We can also generate liquidity for the parent company and PNC’s non-bank subsidiaries through the issuance of debt and equity securities, including certain capital instruments, in public or private markets and commercial paper.
We have an effective shelf registration statement pursuant to which we can issue additional debt, equity and other capital instruments.
During 2014, we issued the following parent company debt under our shelf registration statement: ?
$750 million of subordinated notes with a maturity date of April 29, 2024.
Interest is payable semiannually, at a fixed rate of 3.90%, on April 29 and October 29 of each year, beginning on October 29, 2014.
Total parent company senior and subordinated debt and hybrid capital instruments decreased to $10.1 billion at December 31, 2014 from $10.7 billion at December 31, 2013 due to the following activity in the period.
Table 45: Parent Company Senior and Subordinated Debt and Hybrid Capital Instruments
## Table 1 ##
On October 16, 2014, the parent company established a $5.0 billion commercial paper program to provide additional liquidity.
As of December 31, 2014, there were no issuances outstanding under this program.
Following the establishment of this parent company program, PNC Funding Corp terminated its $3.0 billion commercial paper program.
Note 17 Equity in the Notes To Consolidated Financial Statements in Item 8 of this Report describes the 16,885,192 warrants outstanding, each to purchase one share of PNC common stock at an exercise price of $67.33 per share.
These warrants were sold by the U. S.  Treasury in a secondary public offering in May 2010 after the U. S.  Treasury exchanged its TARP Warrant.
These warrants will expire December 31, 2018, and are considered in the calculation of diluted earnings per common share in Note 16 Earnings Per Share in the Notes To Consolidated Financial Statements in Item 8 of this Report.
Status of Credit Ratings The cost and availability of short-term and long-term funding, as well as collateral requirements for certain derivative instruments, is influenced by PNC’s debt ratings.
In general, rating agencies base their ratings on many quantitative and qualitative factors, including capital adequacy, liquidity, asset quality, business mix, level and quality of earnings, and the current legislative and regulatory environment, including implied government support.

NOTE 4 PURCHASED LOANS Purchased Impaired Loans Purchased impaired loan accounting addresses differences between contractual cash flows and cash flows expected to be collected from the initial investment in loans if those differences are attributable, at least in part, to credit quality.
Several factors were considered when evaluating whether a loan was considered a purchased impaired loan, including the delinquency status of the loan, updated borrower credit status, geographic information, and updated LTV.
GAAP allows purchasers to account for loans individually or to aggregate purchased impaired loans acquired in the same fiscal quarter into one or more pools, provided that the loans have common risk characteristics.
A pool is then accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows.
Purchased impaired homogeneous consumer, residential real estate and smaller balance commercial loans with common risk characteristics are aggregated into pools where appropriate, whereas commercial loans with a total commitment greater than a defined threshold are accounted for individually.
For pooled loans, proceeds of individual loans are not applied individually to each loan within a pool, but to the pool’s recorded investment since it is accounted for as a single asset.
Upon final disposition of a loan within a pool (e. g. , payoff, short-sale, foreclosure, etc.
), the loan’s carrying value is removed from the pool and any gain or loss associated with the transaction is retained in the pool’s recorded investment.
For example, upon final disposition of a loan by short-sale, the proceeds of the shortsale may be less (or more) than the loan’s recorded investment.
This shortfall or loss (excess or gain) is not accounted for as an individual loan sale in our income statement and is instead retained as part of the pool’s recorded investment consistent with our accounting for the pool as a single asset.
This treatment is designed to maintain a constant effective yield for recognition of interest income.
Accordingly, a pool’s recorded investment includes the net accumulation of realized losses or gains attributable to these final dispositions.
As there are no future expected cash flows related to these dispositions, their net carrying value is $0.
The recorded investment, including these realized losses and gains, is evaluated for collectability based upon the net present value of the pool’s remaining expected cash flows when establishing our allowance for loan losses.
See below and Note 1 Accounting Policies and Note 5 Allowances for Loan and Lease Losses and Unfunded Loan Commitments and Letters of Credit for additional information.
The following table provides balances of purchased impaired loans at December 31, 2014 and December 31, 2013: Table 71: Purchased Impaired Loans – Balances
## Table 2 ##
(a) Outstanding balance represents the balance on the loan servicing system for active loans.
It is possible for the outstanding balance to be lower than the recorded investment for certain loans due to the use of pool accounting.
The excess of undiscounted cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized as interest income over the remaining life of the loan using the constant effective yield method.
The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference and is not recognized in income.
Subsequent changes in the expected cash flows of individual or pooled purchased impaired loans will either impact the accretable yield or result in an impairment charge to provision for credit losses in the period in which the changes become probable.
Decreases to the net present value of expected cash flows will generally result in an impairment charge recorded as a provision for credit losses, resulting in an increase to the allowance for loan and lease losses, and a reclassification from accretable yield to non-accretable difference.
