Notes to the Consolidated Financial Statements The Credit Agreement provides that loans will bear interest at rates based, at the Company’s option, on one of two specified base rates plus a margin based on certain formulas defined in the Credit Agreement.
Additionally, the Credit Agreement contains a commitment fee on the amount of unused commitment under the Credit Agreement ranging from 0.125% to 0.625% per annum.
The applicable interest rate and the commitment fee will vary depending on the ratings established by Standard & Poor’s Financial Services LLC and Moody’s Investor Service Inc.  for the Company’s non-credit enhanced, longterm, senior, unsecured debt.
The Credit Agreement contains usual and customary restrictive covenants for facilities of its type, which include, with specified exceptions, limitations on the Company’s ability to create liens or other encumbrances, to enter into sale and leaseback transactions and to enter into consolidations, mergers or transfers of all or substantially all of its assets.
The Credit Agreement also requires the Company to maintain a ratio of total indebtedness to total capitalization, as defined in the Credit Agreement, of sixty percent or less.
The Credit Agreement contains customary events of default that would permit the lenders to accelerate the repayment of any loans, including the failure to make timely payments when due under the Credit Agreement or other material indebtedness, the failure to satisfy covenants contained in the Credit Agreement, a change in control of the Company and specified events of bankruptcy and insolvency.
There were no amounts outstanding under the Credit Agreement at December 31, 2010.
On November 12, 2010, PPG completed a public offering of $250 million in aggregate principal amount of its 1.900% Notes due 2016 (the “2016 Notes”), $500 million in aggregate principal amount of its 3.600% Notes due 2020 (the “2020 Notes”) and $250 million in aggregate principal amount of its 5.500% Notes due 2040 (the “2040 Notes”).
These notes were issued pursuant to an indenture dated as of March 18, 2008 (the “Original Indenture”) between the Company and The Bank of New York Mellon Trust Company, N. A. , as trustee (the “Trustee”), as supplemented by a first supplemental indenture dated as of March 18, 2008 between the Company and the Trustee (the “First Supplemental Indenture”) and a second supplemental indenture dated as of November 12, 2010 between the Company and the Trustee (the “Second Supplemental Indenture” and, together with the Original Indenture and the First Supplemental Indenture, the “Indenture”).
The Company may issue additional debt from time to time pursuant to the Original Indenture.
The Indenture governing these notes contains covenants that limit the Company’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale-leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company’s assets.
The terms of these notes also require the Company to make an offer to repurchase Notes upon a Change of Control Triggering Event (as defined in the Second Supplemental Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest.
Cash proceeds from this notes offering was $983 million (net of discount and issuance costs).
The discount and issuance costs related to these notes, which totaled $17 million, will be amortized to interest expense over the respective terms of the notes.
PPG’s non-U.
S.  operations have uncommitted lines of credit totaling $791 million of which $31 million was used as of December 31, 2010.
These uncommitted lines of credit are subject to cancellation at any time and are generally not subject to any commitment fees.
Short-term debt outstanding as of December 31, 2010 and 2009, was as follows:
## Table 0 ##
PPG is in compliance with the restrictive covenants under its various credit agreements, loan agreements and indentures.
The Company’s revolving credit agreements include a financial ratio covenant.
The covenant requires that the amount of total indebtedness not exceed 60% of the Company’s total capitalization excluding the portion of accumulated other comprehensive income (loss) related to pensions and other postretirement benefit adjustments.
As of December 31, 2010, total indebtedness was 45% of the Company’s total capitalization excluding the portion of accumulated other comprehensive income (loss) related to pensions and other postretirement benefit adjustments.
Additionally, substantially all of the Company’s debt agreements contain customary crossdefault provisions.
Those provisions generally provide that a default on a debt service payment of $10 million or more for longer than the grace period provided (usually 10 days) under one agreement may result in an event of default under other agreements.
None of the Company’s primary debt obligations are secured or guaranteed by the Company’s affiliates.
Interest payments in 2010, 2009 and 2008 totaled $189 million, $201 million and $228 million, respectively.
Notes to the Consolidated Financial Statements employees and their dependents.
These programs require retiree contributions based on retiree-selected coverage levels for certain retirees and their dependents and provide for sharing of future benefit cost increases between PPG and participants based on management discretion.
The Company has the right to modify or terminate certain of these benefit plans in the future.
Salaried and certain hourly employees hired on or after October 1, 2004, are not eligible for postretirement medical benefits.
Salaried employees hired, rehired or transferred to salaried status on or after January 1, 2006, and certain hourly employees hired in 2006 or thereafter are eligible to participate in a defined contribution retirement plan.
These employees are not eligible for defined benefit pension plan benefits.
The Medicare Act of 2003 introduced a prescription drug benefit under Medicare (“Medicare Part D”) that provides several options for Medicare eligible participants and employers, including a federal subsidy payable to companies that elect to provide a retiree prescription drug benefit which is at least actuarially equivalent to Medicare Part D.  During the third quarter of 2004, PPG concluded its evaluation of the provisions of the Medicare Act and decided to maintain its retiree prescription drug program and to take the subsidy available under the Medicare Act.
The federal subsidy related to providing a retiree prescription drug benefit is not subject to U. S.  federal income tax and is recorded as a reduction in annual net periodic benefit cost of other postretirement benefits.
In August 2007, the Company’s U. S.  other postretirement benefit plan was amended to consolidate the number of retiree health care options available for certain retirees and their dependents.
The amendment was effective January 1, 2008.
The amended plan also offered a fully-insured Medicare Part D prescription drug plan for certain retirees and their dependents.
As such, beginning in 2008 PPG was no longer eligible to receive the subsidy provided under the Medicare Act of 2003 for these retirees and their dependents.
In October 2009, the Company decided, effective January 1, 2010, to return to a self-insured Medicare Part D prescription drug plan for certain retirees and their dependents that is at least actuarially equivalent to Medicare Part D.  As such, effective January 1, 2010, PPG was eligible to receive the subsidy provided under the Medicare Act of 2003 for these retirees and their dependents.
The following table sets forth the changes in projected benefit obligations (“PBO”) (as calculated as of December 31), plan assets, the funded status and the amounts recognized in the accompanying consolidated balance sheet for the Company’s defined benefit pension and other postretirement benefit plans:
## Table 1 ##
The PBO is the actuarial present value of benefits attributable to employee service rendered to date, including the effects of estimated future pay increases.
The accumulated benefit obligation (“ABO”) is the actuarial present value of benefits attributable to employee service rendered to date, but does not include the effects of estimated future pay increases.
The ABO for all defined benefit pension plans as of December 31, 2010 and 2009 was $4,695 million and $4,245 million, respectively
Notes to the Consolidated Financial Statements related to the change in the unrealized gain (loss) on derivatives for the years ended December 31, 2010, 2009 and 2008 was $1 million, $(16) million and $30 million, respectively.19.
Employee Savings Plan PPG’s Employee Savings Plan (“Savings Plan”) covers substantially all U. S.  employees.
The Company makes matching contributions to the Savings Plan based upon participants’ savings, subject to certain limitations.
For most participants not covered by a collective bargaining agreement, Company-matching contributions are established each year at the discretion of the Company and are applied to a maximum of 6% of eligible participant compensation.
For those participants whose employment is covered by a collective bargaining agreement, the level of Companymatching contribution, if any, is determined by the collective bargaining agreement.
The Company-matching contribution was 100% for 2008 and for the first two months of 2009.
The Companymatching contribution was suspended from March 2009 through June 2010 as a cost savings measure in recognition of the adverse impact of the global recession.
Effective July 1, 2010, the Company match was reinstated at 50% on the first 6% contributed for most employees eligible for the Company-matching contribution feature.
This would have included the bargained employees in accordance with their collective bargaining agreements.
On January 1, 2011, the Company match was increased to 75% on the first 6% contributed by these eligible employees.
Compensation expense and cash contributions related to the Company match of participant contributions to the Savings Plan for 2010, 2009 and 2008 totaled $9 million, $7 million and $42 million, respectively.
A portion of the Savings Plan qualifies under the Internal Revenue Code as an Employee Stock Ownership Plan.
As a result, the tax deductible dividends on PPG shares held by the Savings Plan were $24 million, $28 million and $29 million for 2010, 2009 and 2008, respectively.20.
Other Earnings
## Table 2 ##
21.
Stock-Based Compensation The Company’s stock-based compensation includes stock options, restricted stock units (“RSUs”) and grants of contingent shares that are earned based on achieving targeted levels of total shareholder return.
All current grants of stock options, RSUs and contingent shares are made under the PPG Industries, Inc.
Omnibus Incentive Plan (“PPG Omnibus Plan”).
Shares available for future grants under the PPG Omnibus Plan were 4.1 million as of December 31, 2010.
Total stock-based compensation cost was $52 million, $34 million and $33 million in 2010, 2009 and 2008, respectively.
The total income tax benefit recognized in the accompanying consolidated statement of income related to the stock-based compensation was $18 million, $12 million and $12 million in 2010, 2009 and 2008, respectively.
Stock Options PPG has outstanding stock option awards that have been granted under two stock option plans: the PPG Industries, Inc.  Stock Plan (“PPG Stock Plan”) and the PPG Omnibus Plan.
Under the PPG Omnibus Plan and the PPG Stock Plan, certain employees of the Company have been granted options to purchase shares of common stock at prices equal to the fair market value of the shares on the date the options were granted.
The options are generally exercisable beginning from six to 48 months after being granted and have a maximum term of 10 years.
Upon exercise of a stock option, shares of Company stock are issued from treasury stock.
The PPG Stock Plan includes a restored option provision for options originally granted prior to January 1, 2003 that allows an optionee to exercise options and satisfy the option price by certifying ownership of mature shares of PPG common stock with equivalent market value.
The fair value of stock options issued to employees is measured on the date of grant and is recognized as expense over the requisite service period.
PPG estimates the fair value of stock options using the Black-Scholes option pricing model.
The risk-free interest rate is determined by using the U. S.  Treasury yield curve at the date of the grant and using a maturity equal to the expected life of the option.
The expected life of options is calculated using the average of the vesting term and the maximum term, as prescribed by accounting guidance on the use of the simplified method for determining the expected term of an employee share option.
This method is used as the vesting term of stock options was changed to three years in 2004 and, as a result, the historical exercise data does not provide a reasonable basis upon which to estimate the expected life of options.
The expected dividend yield and volatility are based on historical stock prices and dividend amounts over past time periods equal in length to the expected life of the options.
Cash from continuing operating activities was $1,809 million, $1,576 million, and $1,176 million in 2013, 2012, and 2011, respectively.
Cash from operations in 2013 compared to 2012 was aided by higher income from continuing operations which was driven by income from acquired businesses.
Cash from operations in 2012 compared to 2011 was aided by cash received from a decrease in working capital.
Operating Working Capital is a subset of total working capital and represents (1) trade receivables-net of the allowance for doubtful accounts, plus (2) inventories on a firstin, first-out (“FIFO”) basis, less (3) trade creditors’ liabilities.
See Note 3, “Working Capital Detail” under Item 8 of this Form 10-K for further information related to the components of the Company’s Operating Working Capital.
We believe Operating Working Capital represents the key components of working capital under the operating control of our businesses.
Operating Working Capital at December 31, 2013 and 2012 was $2.7 billion and $2.9 billion, respectively.
A key metric we use to measure our working capital management is Operating Working Capital as a percentage of sales (fourth quarter sales annualized).
