Financial Statements	NOTE 1: FINANCIAL STATEMENTS

	Ryerson Holding Corporation (“Ryerson”), a Delaware corporation, is the parent company of Joseph T. Ryerson & Son, Inc. (“JT Ryerson”), a Delaware corporation. Affiliates of Platinum Equity, LLC (“Platinum”) own approximately 21,037,500 shares of our common stock, which is approximately 66% of our issued and outstanding common stock.

	Ryerson conducts materials distribution operations in the United States through JT Ryerson, in Canada through its indirect wholly-owned subsidiary Ryerson Canada, Inc., a Canadian corporation (“Ryerson Canada”) and in Mexico through its indirect wholly-owned subsidiary Ryerson Metals de Mexico, S. de R.L. de C.V., a Mexican corporation (“Ryerson Mexico”). In addition to our North American operations, we conduct materials distribution operations in China through Ryerson China Limited (“Ryerson China”), and in Brazil through Açofran Aços e Metais Ltda (“Açofran”), a company in which we have a 50% direct ownership percentage. Unless the context indicates otherwise, Ryerson, JT Ryerson, Ryerson Canada, Ryerson China, Ryerson Mexico and Açofran together with their subsidiaries, are collectively referred to herein as “Ryerson,” “we,” “us,” “our,” or the “Company.”

	On July 23, 2014, our Board of Directors approved a 4.25 for 1.00 stock split of the Company’s common stock effective August 5, 2014. Per share and share amounts presented herein have been adjusted for all periods presented to give retroactive effect to 4.25 for 1.00 stock split.

	On August 13, 2014, Ryerson completed an initial public offering of 11 million shares of common stock at a price to the public of $11.00 per share. Net proceeds from the offering totaled $112.4 million, after deducting the underwriting discount and offering expenses, and were used to (i) redeem $99.5 million in aggregate principal amount of the 11 1⁄4% Senior Notes due 2018 (the “2018 Notes”), (ii) pay Platinum Equity Advisors, LLC (“Platinum Advisors”) and its affiliates $15.0 million of the $25.0 million owed as consideration for terminating the advisory services agreement between JT Ryerson and Platinum Advisors, an affiliate of Platinum (the remaining $10.0 million will be paid in August 2015) and (iii) pay related transaction fees, expenses and debt redemption premiums in connection with the offering, which were approximately $11.2 million. We borrowed an additional $23.3 million under our amended and restated $1.35 billion revolving credit facility (the “Ryerson Credit Facility”) as part of the funding of these transactions.

	The following table shows our percentage of sales by major product lines for the three months ended March 31, 2015 and 2014, respectively:

Accounting Policies [Abstract]
Recent Accounting Pronouncements	NOTE 2: RECENT ACCOUNTING PRONOUNCEMENTS

	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-08 “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This update amends the criteria for reporting discontinued operations to, among other things, raise the threshold for disposals to qualify as discontinued operations. Under the revised standard, a discontinued operation must represent a strategic shift that has or will have a major effect on an entity’s operations and financial results. The revised standard will also allow an entity to have certain continuing cash flows or involvement with the component after the disposal. This update is effective for interim and annual reporting periods, beginning after December 15, 2014, with early adoption permitted. We adopted this guidance for our fiscal year beginning January 1, 2015. The adoption did not have a material impact on our financial statements.

	In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers”, which creates ASC 606 “Revenue from Contracts with Customers” and supersedes the revenue recognition requirements in ASC 605 “Revenue Recognition”. The update outlines a comprehensive model for all entities to use in accounting for revenue arising from contracts with customers as well as required disclosures. Entities have the option of using either a full retrospective or modified approach to adopt the new guidance. This update is effective for annual reporting periods beginning after December 15, 2016. We will adopt this guidance for our fiscal year beginning January 1, 2017. We have not decided upon the method of adoption and we are still evaluating the impact the new standard will have, if any, to our financial statements.

	In August 2014, the FASB issued ASU 2014-15 “Presentation of Financial Statements – Going Concern (Subtopic 205-40), Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” The guidance in ASU 2014-15 sets forth management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern as well as required disclosures. ASU 2014-15 indicates that, when preparing financial statements for interim and annual periods, management should evaluate whether conditions or events, in the aggregate, raise substantial doubt about the entity’s ability to continue as a going concern one year from the date the financial statements are issued or are available to be issued. This evaluation should include consideration of conditions and events that are either known or are reasonably knowable at the date the financial statements are issued or are available to be issued, as well as whether it is probable that management’s plans to address the substantial doubt will be implemented and, if so, whether it is probable that the plans will alleviate the substantial doubt. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods and annual periods thereafter. Early adoption is permitted. We will adopt this guidance for our fiscal year ending December 31, 2016. The adoption of this guidance is not expected to have an impact on our financial statements.

	In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The update requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. If the Company adopted this guidance as of March 31, 2015, the impact of the ASU would result in the reclassification of approximately $15 million of capitalized debt issuance costs from non-current deferred charges and other assets to long-term debt. We will adopt this guidance for our fiscal year beginning January 1, 2016.

	In April 2015, the FASB issued ASU 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the update specifies that the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. The update further specifies that the customer should account for a cloud computing arrangement as a service contract if the arrangement does not include a software license. ASU 2015-05 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. We will adopt this guidance for our fiscal year beginning January 1, 2016. The adoption of this guidance is not expected to have an impact on our financial statements.

Inventories

Inventory Disclosure [Abstract]
Inventories	NOTE 3: INVENTORIES
	The Company primarily uses the last-in, first-out (LIFO) method of valuing inventory. Interim LIFO calculations are based on actual inventory levels.

	Inventories, at stated LIFO value, were classified at March 31, 2015 and December 31, 2014 as follows:


		March 31,		December 31,
		2015		2014
		(In millions)
	In process and finished products	$	663.3	$	738.9
	If current cost had been used to value inventories, such inventories would have been $37 million and $25 million lower than reported at March 31, 2015 and December 31, 2014, respectively. Approximately 89% and 90% of inventories are accounted for under the LIFO method at March 31, 2015 and December 31, 2014, respectively. Non-LIFO inventories consist primarily of inventory at our foreign facilities using the weighted-average cost and the specific cost methods. Substantially all of our inventories consist of finished products.
	The Company has consignment inventory at certain customer locations, which totaled $10.6 million and $10.0 million at March 31, 2015 and December 31, 2014, respectively.

Goodwill and Other Intangible Assets	Goodwill, which represents the excess of cost over the fair value of net assets acquired, amounted to $101.3 million at March 31, 2015. Pursuant to ASC 350, “Intangibles – Goodwill and Other,” we review the recoverability of goodwill annually as of October 1 or whenever significant events or changes occur which might impair the recovery of recorded amounts. The most recently completed impairment test of goodwill was performed as of October 1, 2014 and it was determined that no impairment existed. Other intangible assets with finite useful lives continue to be amortized over their useful lives. We review the recoverability of our long-lived assets whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable.

	Ryerson Credit Facility

	On April 3, 2013, Ryerson amended and restated its $1.35 billion revolving credit facility agreement (as amended and restated, the “Ryerson Credit Facility”), to, among other things, extend the maturity date to the earlier of (a) April 3, 2018 or (b) August 16, 2017 (60 days prior to the scheduled maturity date of the 9% Senior Secured Notes due October 15, 2017 (“2017 Notes”)), if the 2017 Notes are then outstanding. At March 31, 2015, the Company had $407.0 million of outstanding borrowings, $20 million of letters of credit issued and $235 million available under the $1.35 billion Ryerson Credit Facility compared to $435.0 million of outstanding borrowings, $20 million of letters of credit issued and $245 million available at December 31, 2014. Total credit availability is limited by the amount of eligible accounts receivable and inventory pledged as collateral under the agreement insofar as the Company is subject to a borrowing base comprised of the aggregate of these two amounts, less applicable reserves. Eligible accounts receivable, at any date of determination, are comprised of the aggregate value of all accounts directly created by a borrower in the ordinary course of business arising out of the sale of goods or the rendition of services, each of which has been invoiced, with such receivables adjusted to exclude various ineligible accounts, including, among other things, those to which a borrower does not have sole and absolute title and accounts arising out of a sale to an employee, officer, director, or affiliate of a borrower. Eligible inventory, at any date of determination, is comprised of the aggregate value of all inventory owned by a borrower, with such inventory adjusted to exclude various ineligible inventory, including, among other things, any inventory that is classified as “supplies” or is unsaleable in the ordinary course of business and 50% of the value of any inventory that (i) has not been sold or processed within a 180 day period and (ii) which is calculated to have more than 365 days of supply based upon the immediately preceding 6 months consumption. The weighted average interest rate on the borrowings under the Ryerson Credit Facility was 2.2 percent and 2.0 percent at March 31, 2015 and December 31, 2014, respectively.

	The total $1.35 billion revolving credit facility has an allocation of $1.215 billion to the Company’s subsidiaries in the United States and an allocation of $135 million to Ryerson Canada. Amounts outstanding under the U.S. facility bear interest at a rate determined by reference to the base rate (Bank of America’s prime rate) or a LIBOR rate or, for the Canadian facility a rate determined by reference to the Canadian base rate (Bank of America-Canada Branch’s “Base Rate” for loans in U.S. Dollars in Canada) or the BA rate (average annual rate applicable to Canadian Dollar bankers’ acceptances) or a LIBOR rate and the Canadian prime rate (Bank of America-Canada Branch’s “Prime Rate.”). The spread over the base rate and Canadian prime rate is between 0.50% and 1.00% and the spread over the LIBOR and for the bankers’ acceptances is between 1.50% and 2.00%, depending on the amount available to be borrowed. Overdue amounts and all amounts owed during the existence of a default bear interest at 2% above the rate otherwise applicable thereto. The Company also pays commitment fees on amounts not borrowed at a rate between 0.25% and 0.375% depending on the average borrowings as a percentage of the total $1.35 billion agreement during a rolling three month period.

	Borrowings under the Ryerson Credit Facility are secured by (i) in the case of the U.S. facility, first-priority liens on all of the inventory, accounts receivable, lockbox accounts (excluding any proceeds therein of collateral securing the 2017 Notes on a first priority lien basis) and related U.S. assets of JT Ryerson, the other U.S. subsidiary borrowers and certain other U.S. subsidiaries of the Company that act as guarantors, and (ii) in the case of the Canadian facility, the assets securing the U.S. Facility and also first priority liens on all of the inventory, accounts receivable, lockbox accounts and related assets of Ryerson’s Canadian subsidiary borrower and its Canadian subsidiaries that act as guarantors thereof.

	The Ryerson Credit Facility contains covenants that, among other things, restrict the Company and its subsidiaries with respect to the incurrence of debt, the creation of liens, transactions with affiliates, mergers and consolidations, sales of assets and acquisitions. The Ryerson Credit Facility also requires that, if availability under such facility falls below a certain level, the Company maintain a minimum fixed charge coverage ratio as of the end of each calendar month.

	The Ryerson Credit Facility contains events of default with respect to, among other things, default in the payment of principal when due or the payment of interest, fees and other amounts due thereunder after a specified grace period, material misrepresentations, failure to perform certain specified covenants, certain bankruptcy events, the invalidity of certain security agreements or guarantees, material judgments and the occurrence of a change of control of the Company. If such an event of default occurs, the lenders under the Ryerson Credit Facility will be entitled to various remedies, including acceleration of amounts outstanding under the Ryerson Credit Facility and all other actions permitted to be taken by secured creditors.

	The lenders under the Ryerson Credit Facility have the ability to reject a borrowing request if any event, circumstance or development has occurred that has had or could reasonably be expected to have a material adverse effect on the Company. If JT Ryerson or any significant subsidiaries of the other borrowers becomes insolvent or commences bankruptcy proceedings, all amounts borrowed under the Ryerson Credit Facility will become immediately due and payable.

	Proceeds from borrowings under the Ryerson Credit Facility and repayments of borrowings thereunder that are reflected in the Consolidated Statements of Cash Flows represent borrowings under the Company’s revolving credit agreement with original maturities greater than three months. Net proceeds (repayments) under the Ryerson Credit Facility represent borrowings under the Ryerson Credit Facility with original maturities less than three months.

	2017 and 2018 Notes

	On October 10, 2012, JT Ryerson issued $600 million in aggregate principal amount of the 2017 Notes and $300 million in aggregate principal amount of the 2018 Notes (together with the 2017 Notes, the “2017 and 2018 Notes”). The 2017 Notes bear interest at a rate of 9% per annum. The 2018 Notes bear interest at a rate of 11.25% per annum. The 2017 Notes are fully and unconditionally guaranteed on a senior secured basis and the 2018 Notes are fully and unconditionally guaranteed on a senior unsecured basis by all of our existing and future domestic subsidiaries that are co-borrowers or that have guarantee obligations under the Ryerson Credit Facility.



	The 2017 Notes and related guarantees are secured by a first-priority lien on substantially all of our and our guarantors’ present and future assets located in the United States (other than receivables, inventory, related general intangibles, certain other assets and proceeds thereof), subject to certain exceptions and customary permitted liens. The 2017 Notes and related guarantees are secured on a second-priority basis by a lien on the assets that secure our obligations under the Ryerson Credit Facility. The 2018 Notes are not secured. The 2017 and 2018 Notes contain customary covenants that, among other things, limit, subject to certain exceptions, our ability, and the ability of our restricted subsidiaries, to incur additional indebtedness, pay dividends on our capital stock or repurchase our capital stock, make investments, sell assets, engage in acquisitions, mergers or consolidations or create liens or use assets as security in other transactions. Subject to certain exceptions, JT Ryerson may only pay dividends to Ryerson to the extent of 50% of future net income, once prior losses are offset.

	The 2017 Notes will become redeemable by the Company, in whole or in part, at any time on or after April 15, 2015 (the “2017 Redemption Date”) and the 2018 Notes will become redeemable, in whole or in part, at any time on or after October 15, 2015 (the “2018 Redemption Date”), in each case at specified redemption prices. The 2017 and 2018 Notes are redeemable prior to such dates, as applicable, at a redemption price equal to 100% of the principal amount, together with accrued and unpaid interest, if any, to the redemption date, plus a make-whole premium. Additionally, we may redeem up to 35% of each of the 2017 and 2018 Notes prior to the 2017 Redemption Date or 2018 Redemption Date, as applicable, with net cash proceeds from certain equity offerings at a price equal to (a) 109.000%, with respect to the 2017 Notes and (b) 111.250%, with respect to the 2018 Notes, of the principal amount thereof, plus any accrued and unpaid interest. On August 13, 2014, Ryerson completed an initial public offering of 11 million shares of common stock at a price to the public of $11.00 per share. Net proceeds from the offering were used to redeem $99.5 million in aggregate principal amount of the 2018 Notes and pay redemption premiums of $11.2 million, which were recorded within other income and (expense), net. If a change of control occurs, JT Ryerson must offer to purchase the 2017 and 2018 Notes at 101% of their principal amount, plus accrued and unpaid interest.

Commitments and Contingencies	NOTE 8: COMMITMENTS AND CONTINGENCIES
	From time to time, we are named as a defendant in legal actions incidental to our ordinary course of business. We do not believe that the resolution of these claims will have a material adverse effect on our financial position, results of operations or cash flows. We maintain liability insurance coverage to assist in protecting our assets from losses arising from or related to activities associated with business operations.
	In October 2011, the United States Environmental Protection Agency named us as one of more than 100 businesses that may be a potentially responsible party for the Portland Harbor Superfund Site (“Portland Harbor”). We do not currently have sufficient information available to us to determine the total cost of any required investigation or remediation of the Portland Harbor site and therefore, management cannot predict the ultimate outcome of this matter or estimate a range of potential loss at this time.
	There are various claims and pending actions against the Company. The amount of liability, if any, for those claims and actions at March 31, 2015 is not determinable but, in the opinion of management, such liability, if any, will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Derivatives and Fair Value Measurements	NOTE 9: DERIVATIVES AND FAIR VALUE MEASUREMENTS

	Derivatives

	The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are interest rate risk, foreign currency risk, and commodity price risk. Interest rate swaps are entered into to manage interest rate risk associated with the Company’s floating-rate borrowings. We use foreign currency exchange contracts to hedge our Canadian subsidiaries’ variability in cash flows from the forecasted payment of currencies other than the functional currency. From time to time, we may enter into fixed price sales contracts with our customers for certain of our inventory components. We may enter into metal commodity futures and options contracts periodically to reduce volatility in the price of metals. We may also enter into natural gas and diesel fuel price swaps to manage the price risk of forecasted purchases of natural gas and diesel fuel. The Company currently does not account for its derivative contracts as hedges but rather marks them to market with a corresponding offset to current earnings. The Company regularly reviews the creditworthiness of its derivative counterparties and does not expect to incur a significant loss from the failure of any counterparties to perform under any agreements.



	The following table summarizes the location and fair value amount of our derivative instruments reported in our Consolidated Balance Sheets as of March 31, 2015 and December 31, 2014:

As of March 31, 2015 and December 31, 2014, the Company had 593 tons and 144 tons, respectively, of nickel futures or option contracts related to forecasted purchases. As of March 31, 2015 and December 31, 2014, the Company had 10,860 tons and 14,700 tons, respectively, of hot roll steel coil option contracts related to forecasted purchases. The Company has aluminum price swaps related to forecasted purchases, which had a notional amount of 14,597 tons and 6,366 tons as of March 31, 2015 and December 31, 2014, respectively. As of March 31, 2015 and December 31, 2014, the Company has 962,000 gallons and 624,000 gallons, respectively, of diesel fuel hedge contracts related to forecasted purchases.

	Fair Value Measurements

	To increase consistency and comparability in fair value measurements, ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows:


		1	Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date.


		2	Level 2 – inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data.


		3	Level 3 – unobservable inputs, such as internally-developed pricing models for the asset or liability due to little or no market activity for the asset or liability.

The following table presents assets and liabilities measured and recorded at fair value on our Consolidated Balance Sheets on a recurring basis and their level within the fair value hierarchy as of March 31, 2015:

The fair value of each derivative contract is determined using Level 2 inputs and the market approach valuation technique, as described in ASC 820. The Company has various commodity derivatives to lock in nickel prices for varying time periods. The fair value of these derivatives is determined based on the spot price each individual contract was purchased at and compared with the one-month daily average actual spot price on the London Metals Exchange for nickel on the valuation date. The Company also has commodity derivatives to lock in hot roll coil and aluminum prices for varying time periods. The fair value of hot roll coil and aluminum derivatives is determined based on the spot price each individual contract was purchased at and compared with the one-month daily average actual spot price on the New York Mercantile Exchange and the London Metals Exchange, respectively, for the commodity on the valuation date. The Company has various commodity derivatives to lock in diesel prices for varying time periods. The fair value of these derivatives is determined based on the spot price each individual contract was purchased at and compared with the one-month daily average actual spot price of the Platts Index for Gulf Coast Ultra Low Sulfur Diesel on the valuation date. In addition, the Company has numerous foreign exchange contracts to hedge our Canadian subsidiaries’ variability in cash flows from the forecasted payment of currencies other than the functional currency, the Canadian dollar. The Company defines the fair value of foreign exchange contracts as the amount of the difference between the contracted and current market value at the end of the period. The Company estimates the current market value of foreign exchange contracts by obtaining month-end market quotes of foreign exchange rates and forward rates for contracts with similar terms. The Company uses the exchange rates provided by Reuters. Each contract term varies in the number of months, but on average is between 3 to 12 months in length.



The carrying and estimated fair values of the Company’s financial instruments at March 31, 2015 and December 31, 2014 were as follows:



		At March 31, 2015						At December 31, 2014
		Carrying			Fair Value			Carrying			Fair Value
		Amount			Fair Value			Amount			Fair Value
		(In millions)
Cash and cash equivalents		$	70.8		$	70.8		$	60		$	60
Restricted cash			2			2			2			2
Receivables less provision for allowances, claims and doubtful accounts			412.7			412.7			400.8			400.8

Long-term debt, including current portion			1,202.40			1,213.00			1,259.10			1,288.70

The estimated fair value of the Company’s cash and cash equivalents, receivables less provision for allowances, claims and doubtful accounts and accounts payable approximate their carrying amounts due to the short-term nature of these financial instruments. The estimated fair value of the Company’s long-term debt and the current portions thereof is determined by using quoted market prices of Company debt securities (Level 2 inputs).

Assets Held for Sale

The Company had $2.9 million and $2.5 million of assets held for sale, classified within “prepaid expenses and other current assets,” as of March 31, 2015 and December 31, 2014, respectively. The Company recorded a $0.4 million gain and zero in the three months ended March 31, 2015 and 2014, respectively, related to certain assets held for sale in order to recognize the assets at their fair value less cost to sell in accordance with ASC 360-10-35-43, “Property, Plant and Equipment – Other Presentation Matters.” The fair values less costs to sell of long-lived assets held for sale are assessed each reporting period that they remain classified as held for sale. Any increase or decrease in the held for sale long-lived asset’s fair value less cost to sell is reported as an adjustment to its carrying amount, except that the adjusted carrying amount cannot exceed the carrying amount of the long-lived asset at the time it was initially classified as held for sale. The fair values of each property were determined based on appraisals obtained from a third-party, pending sales contracts, or recent listing agreements with third-party brokerage firms.

The following table presents those assets that were measured and recorded at fair value on our Consolidated Balance Sheets on a non-recurring basis and their level within the fair value hierarchy at March 31, 2015:

Available-For-Sale Investments

The Company has classified investments made during 2010 and 2012 as available-for-sale at the time of their purchase. Investments classified as available-for-sale are recorded at fair value with the related unrealized gains and losses included in accumulated other comprehensive income. Management evaluates investments in an unrealized loss position on whether an other-than-temporary impairment has occurred on a periodic basis. Factors considered by management in assessing whether an other-than-temporary impairment has occurred include: the nature of the investment; whether the decline in fair value is attributable to specific adverse conditions affecting the investment; the financial condition of the investee; the severity and the duration of the impairment; and whether we intend to sell the investment or will be required to sell the investment before recovery of its amortized cost basis. When it is determined that an other-than-temporary impairment has occurred, the investment is written down to its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred. The investment has been in a gross unrealized loss position for twelve months. Based on the duration and severity of our unrealized loss, management has determined that an other-than-temporary impairment has occurred and thus recognized a $12.3 million impairment charge within other income and (expense), net for the three months ended March 31, 2015. Realized gains and losses are recorded within the statement of operations upon sale of the security and are based on specific identification.

The Company’s available-for-sale securities as of March 31, 2015 can be summarized as follows:



		At March 31, 2015
		Cost			Gross			Gross			Fair Value
					Unrealized			Unrealized
					Gains			Losses

Income Taxes	NOTE 12: INCOME TAXES

	For the three months ended March 31, 2015, the Company recorded an income tax benefit from operations of $0.2 million compared to tax expense of $3.1 million in the corresponding prior year period. The $0.2 million tax benefit in the first quarter of 2015 primarily represents taxes at local statutory rates where the Company operates, but generally excludes any tax benefit for losses in jurisdictions with historical losses, and the discrete tax effect of the other-than-temporary impairment charge recorded during the quarter.

	In accordance with FASB ASC 740, “Income Taxes,” the Company assesses the realizability of its deferred tax assets. The Company records a valuation allowance when, based upon the evaluation of all available evidence, it is more-likely-than-not that all or a portion of the deferred tax assets will not be realized. In making this determination, we analyze, among other things, our recent history of earnings, the nature and timing of reversing book-tax temporary differences, tax planning strategies and future income. The Company maintains a valuation allowance on certain foreign and U.S. federal and state deferred tax assets until such time as in management’s judgment, considering all available positive and negative evidence, the Company determines that these deferred tax assets are more likely than not realizable. The valuation allowance is reviewed quarterly and will be maintained until sufficient positive evidence exists to support the reversal of some or all of the valuation allowance. The valuation allowance was $22.5 million at March 31, 2015 and December 31, 2014.

Earnings Per Share	NOTE 13: EARNINGS PER SHARE

	On July 16, 2007, Ryerson was capitalized with 21,250,000 shares of common stock by Platinum Equity, LLC. On August 13, 2014, Ryerson completed an initial public offering of 11 million shares of common stock at a price to the public of $11.00 per share. All shares outstanding are common shares and have equal voting, liquidation and preference rights.

	Basic earnings per share attributable to Ryerson’s common stock is determined based on earnings for the period divided by the weighted average number of common shares outstanding during the period. Diluted EPS attributable to Ryerson’s common stock considers the effect of potential common shares, unless inclusion of the potential common shares would have an antidilutive effect. Ryerson does not have any securities or other items that are convertible into common shares, therefore basic and fully diluted EPS are the same.

	The following table sets forth the calculation of basic and diluted earnings (loss) per share:
