Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities The information required by Item 5 regarding market information, including stock exchange listings and quarterly stock market prices, dividends and holders of common stock is included in Exhibit 13.1 filed with this Form 10-K and is incorporated herein by reference.

Directors who are not also officers of the Company receive common stock equivalents pursuant to the PPG Industries, Inc. , Deferred Compensation Plan for Directors (“PPG Deferred Compensation Plan for Directors”).
Common stock equivalents are hypothetical shares of common stock having a value on any given date equal to the value of a share of common stock.
Common stock equivalents earn dividend equivalents that are converted into additional common stock equivalents but carry no voting rights or other rights afforded to a holder of common stock.
The common stock equivalents credited to directors under this plan are exempt from registration under Section 4(a)(2) of the Securities Act of 1933 as private offerings made only to directors of the Company in accordance with the provisions of the plan.
Under the PPG Deferred Compensation Plan for Directors, each director may elect to defer the receipt of all or any portion of the compensation paid to such director for serving as a PPG director.
All deferred payments are held in the form of common stock equivalents.
Payments out of the deferred accounts are made in the form of common stock of the Company (and cash as to any fractional common stock equivalent).
The directors, as a group, were credited with 15,445; 25,724; and 33,540 common stock equivalents in 2015, 2014 and 2013, respectively, under this plan.
The values of the common stock equivalents, when credited, ranged from $90.13 to $98.73 in 2015, $95.59 to $109.91 in 2014, and $69.28 to $91.96 in 2013.

Notes to the Consolidated Financial Statements 1.
Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of PPG Industries, Inc.  (“PPG” or the “Company”) and all subsidiaries, both U. S.  and non-U.
S. , that it controls.
PPG owns more than 50% of the voting stock of most of the subsidiaries that it controls.
For those consolidated subsidiaries in which the Company’s ownership is less than 100%, the outside shareholders’ interests are shown as noncontrolling interests.
Investments in companies in which PPG owns 20% to 50% of the voting stock and has the ability to exercise significant influence over operating and financial policies of the investee are accounted for using the equity method of accounting.
As a result, PPG’s share of the earnings or losses of such equity affiliates is included in the accompanying consolidated statement of income and PPG’s share of these companies’ shareholders’ equity is included in “Investments” in the accompanying consolidated balance sheet.
Transactions between PPG and its subsidiaries are eliminated in consolidation.
Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with U. S.  generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of income and expenses during the reporting period.
Such estimates also include the fair value of assets acquired and liabilities assumed resulting from the allocation of the purchase price related to business combinations consummated.
Actual outcomes could differ from those estimates.
Revenue Recognition The Company recognizes revenue when the earnings process is complete.
Revenue is recognized by all operating segments when goods are shipped and title to inventory and risk of loss passes to the customer or when services have been rendered.
Shipping and Handling Costs Amounts billed to customers for shipping and handling are reported in “Net sales” in the accompanying consolidated statement of income.
Shipping and handling costs incurred by the Company for the delivery of goods to customers are included in “Cost of sales, exclusive of depreciation and amortization” in the accompanying consolidated statement of income.
Selling, General and Administrative Costs Amounts presented as “Selling, general and administrative” in the accompanying consolidated statement of income are comprised of selling, customer service, distribution and advertising costs, as well as the costs of providing corporatewide functional support in such areas as finance, law, human resources and planning.
Distribution costs pertain to the movement and storage of finished goods inventory at companyowned and leased warehouses and other distribution facilities.
Advertising Costs Advertising costs are expensed as incurred and totaled $322 million, $324 million and $297 million in 2016, 2015 and 2014, respectively.
Research and Development Research and development costs, which consist primarily of employee related costs, are charged to expense as incurred.
## Table 1 ##
Legal Costs Legal costs, primarily include costs associated with acquisition and divestiture transactions, general litigation, environmental regulation compliance, patent and trademark protection and other general corporate purposes, are charged to expense as incurred.
Foreign Currency Translation The functional currency of most significant non-U.
S.  operations is their local currency.
Assets and liabilities of those operations are translated into U. S.  dollars using year-end exchange rates; income and expenses are translated using the average exchange rates for the reporting period.
Unrealized foreign currency translation adjustments are deferred in accumulated other comprehensive loss, a separate component of shareholders’ equity.
Cash Equivalents Cash equivalents are highly liquid investments (valued at cost, which approximates fair value) acquired with an original maturity of three months or less.
Short-term Investments Short-term investments are highly liquid, high credit quality investments (valued at cost plus accrued interest) that have stated maturities of greater than three months to one year.
The purchases and sales of these investments are classified as investing activities in the consolidated statement of cash flows.
Marketable Equity Securities The Company’s investment in marketable equity securities is recorded at fair market value and reported in “Other current assets” and “Investments” in the accompanying consolidated balance sheet with changes in fair market value recorded in income for those securities designated as trading securities and in other comprehensive income, net of tax, for those designated as available for sale securities.
Notes to the Consolidated Financial Statements 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, as defined in the Credit Agreement, on the amount of unused commitments under the Credit Agreement ranging from 0.080% to 0.225% per annum.
The average Commitment Fee in 2016 was 0.09%, and PPG is committed to pay 0.09% in 2017.
The Credit Agreement also supports the Company’s commercial paper borrowings.
As a result, the commercial paper borrowings as of December 31, 2015 were classified as longterm debt based on PPG’s intent and ability to refinance these borrowings on a long-term basis.
There were no commercial paper borrowings outstanding as of December 31, 2016.
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 maintains the same restrictive covenant as the prior credit agreement whereby the Company must maintain a ratio of Total Indebtedness to Total Capitalization, as defined in the Credit Agreement, of 60% or less.
As of December 31, 2016, total indebtedness was 45% of the Company’s total capitalization.
The Credit Agreement also contains customary events of default, 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 that would permit the lenders to accelerate the repayment of any loans.
