Business and Basis of Presentation	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	Business and Basis of Presentation
	Nature of Business
	Prestige Brands Holdings, Inc. (referred to herein as the “Company” or “we”, which reference shall, unless the context requires otherwise, be deemed to refer to Prestige Brands Holdings, Inc. and all of its direct and indirect 100% owned subsidiaries on a consolidated basis) is engaged in the marketing, sales and distribution of over-the-counter (“OTC”) healthcare and household cleaning products to mass merchandisers, drug stores, supermarkets, and club, convenience, and dollar stores in North America (the United States and Canada) and in Australia and certain other international markets.  Prestige Brands Holdings, Inc. is a holding company with no operations and is also the parent guarantor of the senior credit facility and the senior notes described in Note 10 to these Consolidated Financial Statements.
	Basis of Presentation
	Our Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").  All significant intercompany transactions and balances have been eliminated in consolidation.  Our fiscal year ends on March 31st of each year.  References in these Consolidated Financial Statements or notes to a year (e.g., “2015”) mean our fiscal year ended on March 31st of that year.
	Reclassification
	We revised the classification of certain promotional expenses that were incurred in the prior year to correctly present the amounts as a reduction to net sales. The amounts were not material to any of the periods presented.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period.  Although these estimates are based on our knowledge of current events and actions that we may undertake in the future, actual results could differ from those estimates.  As discussed below, our most significant estimates include those made in connection with the valuation of intangible assets, stock-based compensation, fair value of debt, sales returns and allowances, trade promotional allowances and inventory obsolescence, and the recognition of income taxes using an estimated annual effective tax rate.
	Cash and Cash Equivalents
	We consider all short-term deposits and investments with original maturities of three months or less to be cash equivalents.  Substantially all of our cash is held by a large regional bank with headquarters in California.  We do not believe that, as a result of this concentration, we are subject to any unusual financial risk beyond the normal risk associated with commercial banking relationships. The Federal Deposit Insurance Corporation (“FDIC”) and Securities Investor Protection Corporation (“SIPC”) insure these balances, up to $250,000 and $500,000, with a $250,000 limit for cash, respectively. Substantially all of the Company's cash balances at March 31, 2015 are uninsured.
	Accounts Receivable
	We extend non-interest-bearing trade credit to our customers in the ordinary course of business.  We maintain an allowance for doubtful accounts receivable based upon historical collection experience and expected collectability of the accounts receivable.  In an effort to reduce credit risk, we (i) have established credit limits for all of our customer relationships, (ii) perform ongoing credit evaluations of customers’ financial condition, (iii) monitor the payment history and aging of customers’ receivables, and (iv) monitor open orders against an individual customer’s outstanding receivable balance.
	Inventories
	Inventories are stated at the lower of cost or market value, where cost is determined by using the first-in, first-out method.  We reduce inventories for the diminution of value resulting from product obsolescence, damage or other issues affecting marketability, equal to the difference between the cost of the inventory and its estimated market value.  Factors utilized in the determination of estimated market value include (i) current sales data and historical return rates, (ii) estimates of future demand, (iii) competitive pricing pressures, (iv) new product introductions, (v) product expiration dates, and (vi) component and packaging obsolescence.
	Property and Equipment
	Property and equipment are stated at cost and are depreciated using the straight-line method based on the following estimated useful lives:
		Years
	Machinery	5
	Computer equipment and software	3
	Furniture and fixtures	7
	Leasehold improvements	*
	*Leasehold improvements are amortized over the lesser of the lease term or the estimated useful life of the related asset.
	Expenditures for maintenance and repairs are charged to expense as incurred.  When an asset is sold or otherwise disposed of, we remove the cost and associated accumulated depreciation from the accounts and recognize the resulting gain or loss in the Consolidated Statements of Income and Comprehensive Income.
	Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.  An impairment loss is recognized if the carrying amount of the asset exceeds its fair value.
	Goodwill
	The excess of the purchase price over the fair market value of assets acquired and liabilities assumed in purchase business combinations is classified as goodwill.  Goodwill is not amortized, although the carrying value is tested for impairment at least annually in the fourth fiscal quarter of each year, or more frequently if events or changes in circumstances indicate that the asset may be impaired.  Goodwill is tested for impairment at the product group level, which is one level below the operating segment level.
	Intangible Assets
	Intangible assets, which are comprised primarily of trademarks, are stated at cost less accumulated amortization.  For intangible assets with finite lives, amortization is computed using the straight-line method over estimated useful lives, typically ranging from 10 to 30 years.
	Indefinite-lived intangible assets are tested for impairment at least annually in the fourth fiscal quarter of each year, or more frequently if events or changes in circumstances indicate that the asset may be impaired.  Intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts exceed their fair values and may not be recoverable.  An impairment loss is recognized if the carrying amount of the asset exceeds its fair value.
	Deferred Financing Costs
	We have incurred debt origination costs in connection with the issuance of long-term debt.  These costs are capitalized as deferred financing costs and amortized over the term of the related debt using the effective interest method.
	Revenue Recognition
	We recognize revenue when the following criteria are met: (i) persuasive evidence of an arrangement exists; (ii) the selling price is fixed or determinable; (iii) the product has been shipped and the customer takes ownership and assumes the risk of loss; and (iv) collection of the resulting receivable is reasonably assured.  We have determined that these criteria are met and the transfer of the risk of loss generally occurs when product is received by the customer and, accordingly, we recognize revenue at that time.  Provision is made for estimated discounts related to customer payment terms and estimated product returns at the time of sale based on our historical experience.
	As is customary in the consumer products industry, we participate in the promotional programs of our customers to enhance the sale of our products.  The cost of these promotional programs varies based on the actual number of units sold during a finite period of time.  These promotional programs consist of direct-to-consumer incentives, such as coupons and temporary price reductions, as well as incentives to our customers, such as allowances for new distribution, including slotting fees, and cooperative advertising.  Estimates of the costs of these promotional programs are based on (i) historical sales experience, (ii) the current promotional offering, (iii) forecasted data, (iv) current market conditions, and (v) communication with customer purchasing/marketing personnel.  We recognize the cost of such sales incentives by recording an estimate of such cost as a reduction of revenue, at the later of (a) the date the related revenue is recognized, or (b) the date when a particular sales incentive is offered. At the completion of the promotional program, the estimated amounts are adjusted to actual results.
	Due to the nature of the consumer products industry, we are required to estimate future product returns.  Accordingly, we record an estimate of product returns concurrent with recording sales, which is made after analyzing (i) historical return rates, (ii) current economic trends, (iii) changes in customer demand, (iv) product acceptance, (v) seasonality of our product offerings, and (vi) the impact of changes in product formulation, packaging and advertising.
	Cost of Sales
	Cost of sales includes product costs, warehousing costs, inbound and outbound shipping costs, and handling and storage costs.  Shipping, warehousing and handling costs were $37.7 million for 2015, $32.0 million for 2014 and $30.6 million for 2013.
	Advertising and Promotion Costs
	Advertising and promotion costs are expensed as incurred.  Allowances for new distribution costs associated with products, including slotting fees, are recognized as a reduction of sales.  Under these new distribution arrangements, the retailers allow our products to be placed on the stores’ shelves in exchange for such fees.
	Stock-based Compensation
	We recognize stock-based compensation by measuring the cost of services to be rendered based on the grant-date fair value of the equity award.  Compensation expense is to be recognized over the period an employee is required to provide service in exchange for the award, generally referred to as the requisite service period.
	Income Taxes
	Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.  A valuation allowance is established when necessary to reduce deferred tax assets to the amounts expected to be realized.
	The Income Taxes topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740 prescribes a recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.    The guidance only allows the recognition of those tax benefits that have a greater than 50% likelihood of being sustained upon examination by the various taxing authorities. As a result, we have applied a more-likely-than-not recognition threshold for all tax uncertainties.
	We are subject to taxation in the United States and various state and foreign jurisdictions.
	We classify penalties and interest related to unrecognized tax benefits as income tax expense in the Consolidated Statements of Income and Comprehensive Income.
	Earnings Per Share
	Basic earnings per share is calculated based on income available to common stockholders and the weighted-average number of shares outstanding during the reporting period.  Diluted earnings per share is calculated based on income available to common stockholders and the weighted-average number of common and potential common shares outstanding during the reporting period.  Potential common shares, composed of the incremental common shares issuable upon the exercise of stock options, stock appreciation rights and unvested restricted shares, are included in the earnings per share calculation to the extent that they are dilutive.
	Recently Issued Accounting Standards
	In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from that carrying amount of that debt liability, consistent with debt discounts. The amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of ASU 2015-03 is not expected to have a material impact on our Consolidated Financial Statements.
	In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis. Update 2015-02 amended the process that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amendments in this update are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The adoption of ASU 2015-02 is not expected to have a material impact on our Consolidated Financial Statements.
	In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items. The amendments in this update eliminate the concept of extraordinary items in Subtopic 225-20, which required entities to consider whether an underlying event or transaction is extraordinary. However, the amendments retain the presentation and disclosure guidance for items that are unusual in nature or occur infrequently. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. The adoption of ASU 2015-01 is not expected to have a material impact on our Consolidated Financial Statements.
	In November 2014, the FASB issued ASU 2014-17, Pushdown Accounting, which clarifies whether and at what threshold an acquired entity that is a business or nonprofit activity can apply pushdown accounting in its separate financial statements. This ASU provides companies with the option to apply pushdown accounting in its separate financial statements upon the occurrence of an event in which an acquirer obtains control of the acquired entity. The election to apply pushdown accounting can be made either in the period in which the change of control occurred, or in a subsequent period. The amendments in this update were effective November 18, 2014. The adoption of ASU 2014-17 did not have a material impact on our Consolidated Financial Statements.
	In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This amendment states that in connection with preparing financial statements for each annual and interim reporting period, an entity's management should evaluate whether there are conditions or events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued, when applicable). The amendments in this update are effective for the annual reporting period beginning after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The adoption of ASU 2014-15 is not expected to have a material impact on our Consolidated Financial Statements.
	In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could Be Achieved after the Requisite Service Period, which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the new guidance does not allow for a performance target that affects vesting to be reflected in estimating the fair value of the award at the grant date. The amendments to this update are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in this update either prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We currently do not have any outstanding share-based payments with a performance target. The adoption of ASU 2014-12 is not expected to have a material impact on our Consolidated Financial Statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers - Topic 606, which supersedes the revenue recognition requirements in FASB ASC 605. The new guidance primarily states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. We are evaluating the impact of adopting this prospective guidance on our Consolidated Financial Statements.
	In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. In addition, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The amendments in this update must be applied prospectively to all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. The adoption of ASU 2014-08 is not expected to have a material impact on our Consolidated Financial Statements.
	Management has reviewed and continues to monitor the actions of the various financial and regulatory reporting agencies and is currently not aware of any other pronouncement that could have a material impact on our consolidated financial position, results of operations or cash flows.

	Acquisition of Insight Pharmaceuticals
	On September 3, 2014, the Company completed the acquisition of Insight Pharmaceuticals Corporation ("Insight"), a marketer and distributor of feminine care and other OTC healthcare products, for $753.2 million in cash. The closing followed the Federal Trade Commission’s (“FTC”) approval of the acquisition and was finalized pursuant to the terms of the purchase agreement announced on April 25, 2014. Pursuant to the Insight purchase agreement, the Company acquired 27 OTC brands sold in North America (including related trademarks, contracts and inventory), which extended the Company's portfolio of OTC brands to include a leading feminine care platform in the United States and Canada anchored by Monistat, the leading North American brand in OTC yeast infection treatment. The acquisition also added brands to the Company's cough & cold, pain relief, ear care and dermatological platforms. In connection with the FTC's approval of the Insight acquisition, we sold one of the competing brands that we acquired from Insight on the same day as the Insight closing. Insight is primarily included in our North American OTC Healthcare segment.
	The Insight acquisition was accounted for in accordance with the Business Combinations topic of the FASB ASC 805, which requires that the total cost of an acquisition be allocated to the tangible and intangible assets acquired and liabilities assumed based upon their respective fair values at the date of acquisition.
	We prepared an analysis of the fair values of the assets acquired and liabilities assumed as of the date of acquisition. The following table summarizes our preliminary allocation of the assets acquired and liabilities assumed as of the September 3, 2014 acquisition date.
	(In thousands)	3-Sep-14
	Cash acquired	$	3,507
	Accounts receivable	25,784
	Inventories	23,559
	Deferred income tax assets - current	860
	Prepaids and other current assets	1,407
	Property, plant and equipment	2,308
	Goodwill	103,255
	Intangible assets	724,374
	Total assets acquired	885,054
	Accounts payable	16,079
	Accrued expenses	8,003
	Deferred income tax liabilities - long term	107,799
	Total liabilities assumed	131,881
	Total purchase price	$	753,173
	Based on this analysis, we allocated $599.6 million to indefinite-lived intangible assets and $124.8 million to amortizable intangible assets. We are amortizing the purchased amortizable intangible assets on a straight-line basis over an estimated weighted average useful life of 16.2 years. The weighted average remaining life for amortizable intangible assets at March 31, 2015 was 15.6 years.
	We also recorded goodwill of $103.3 million based on the amount by which the purchase price exceeded the fair value of the net assets acquired. Goodwill is not deductible for income tax purposes.
	The operating results of Insight have been included in our Consolidated Financial Statements beginning September 3, 2014. Revenues of the acquired Insight operations for the year ended March 31, 2015 were $97.1 million. On September 3, 2014, we sold one of the brands we acquired from the Insight acquisition for $18.5 million, for which we had allocated $17.7 million, $0.6 million and $0.2 million to intangible assets, inventory and property, plant and equipment, respectively.
	The following table provides our unaudited pro forma revenues, net income and net income per basic and diluted common share had the results of Insight's operations been included in our operations commencing on April 1, 2013, based upon available information related to Insight's operations. This pro forma information is not necessarily indicative either of the combined results of operations that actually would have been realized by us had the Insight acquisition been consummated at the beginning of the period for which the pro forma information is presented, or of future results.

	Acquisition of the Hydralyte brand
	On April 30, 2014, we completed the acquisition of the Hydralyte brand in Australia and New Zealand from The Hydration Pharmaceuticals Trust of Victoria, Australia, which was funded through a combination of cash on hand and our existing senior secured credit facility.
	Hydralyte is the leading OTC brand in oral rehydration in Australia and is marketed and sold through our Care Pharmaceuticals Pty Ltd. subsidiary ("Care Pharma"). Hydralyte is available in pharmacies in multiple forms and is indicated for oral rehydration following diarrhea, vomiting, fever, heat and other ailments. Hydralyte is included in our International OTC Healthcare segment.
	The Hydralyte acquisition was accounted for in accordance with the Business Combinations topic of the FASB ASC 805, which requires that the total cost of an acquisition be allocated to the tangible and intangible assets acquired and liabilities assumed based upon their respective fair values at the date of acquisition.
	We prepared an analysis of the fair values of the assets acquired and liabilities assumed as of the date of acquisition. The following table summarizes our allocation of the assets acquired and liabilities assumed as of the April 30, 2014 acquisition date.

	We also recorded goodwill of $1.2 million based on the amount by which the purchase price exceeded the fair value of the net assets acquired. Goodwill is not deductible for income tax purposes.
	The pro forma effect of this acquisition on revenues and earnings was not material.
	Acquisition of Care Pharmaceuticals Pty Ltd.
	On July 1, 2013, we completed the acquisition of Care Pharma, which was funded through a combination of our existing senior secured credit facility and cash on hand.
	The Care Pharma brands include the Fess line of cold/allergy and saline nasal health products, which is the leading saline spray for both adults and children in Australia. Other key brands include Painstop analgesic, Rectogesic for rectal discomfort, and the Fab line of nutritional supplements. Care Pharma also carries a line of brands for children including Little Allergies, Little Eyes, and Little Coughs. The brands acquired are complementary to our OTC Healthcare portfolio.
	This acquisition was accounted for in accordance with the Business Combinations topic of the FASB ASC 805, which requires that the total cost of an acquisition be allocated to the tangible and intangible assets acquired and liabilities assumed based upon their respective fair values at the date of acquisition.
	We prepared a analysis of the fair values of the assets acquired and liabilities assumed as of the date of acquisition. The following table summarizes our allocation of the assets acquired and liabilities assumed as of the July 1, 2013 acquisition date.

We are amortizing the purchased amortizable intangible assets on a straight-line basis over an estimated weighted average useful life of 15.1 years. The weighted average remaining life for amortizable intangible assets at March 31, 2015 was 11.8 years.
We also recorded goodwill of $23.1 million based on the amount by which the purchase price exceeded the fair value of the net assets acquired. The full amount of goodwill is deductible for income tax purposes.

	During the three months ended June 30, 2012, we received a revised post-closing inventory and apportionment adjustment from GSK requiring an additional payment of $0.2 million, which resulted in an increase to our recorded goodwill balance.
	As more fully disclosed in Note 3, on October 31, 2012, we sold the Phazyme brand for $22.3 million. As a result of the divestiture of Phazyme, we reduced goodwill by $6.4 million.
	As discussed in Note 2, on July 1, 2013, we completed the acquisition of Care Pharma. In connection with this acquisition, we recorded goodwill of $23.1 million based on the amount by which the purchase price exceeded the fair value of the net assets acquired.
	As discussed in Note 2, we completed two acquisitions during the year ended March 31, 2015. On September 3, 2014, we completed the acquisition of Insight and recorded goodwill of $103.3 million reflecting the amount by which the purchase price exceeded the preliminary estimate of fair value of net assets acquired. Additionally, on April 30, 2014, we completed the acquisition of the Hydralyte brand and recorded goodwill of $1.2 million reflecting the amount by which the purchase price exceeded the preliminary estimate of fair value of the net assets acquired.
	As further discussed in Note 8, in December 2014, we completed a transaction to sell rights to use of the Comet brand in certain Eastern European countries to a third-party licensee. As a result, we recorded a gain on the sale of such rights in the amount of $1.1 million and reduced the carrying value of our intangible assets and goodwill.
	Under accounting guidelines, goodwill is not amortized, but must be tested for impairment annually, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below the carrying amount. During the fourth quarter of each fiscal year, we perform our annual impairment analysis. In prior years, we performed the analysis as of March 31. However, beginning with fiscal year 2015, we changed the date of our analysis to February 28 to better align with our annual operating plan preparation and to help facilitate our financial reporting process. We do not believe that a one-month change in the date of our analysis will significantly impact the results of our analysis or our financial statements.
	At February 28, 2015 and March 31, 2014, in conjunction with the annual test for goodwill impairment, there were no indicators of impairment under the analysis. Accordingly, no impairment charge was recorded in 2015 or 2014.
	We identify our reporting units in accordance with the FASB ASC Subtopic 280. The carrying value and fair value for intangible assets and goodwill for a reporting unit are calculated based on key assumptions and valuation methodologies previously discussed. The discounted cash flow methodology is a widely-accepted valuation technique utilized by market participants in the transaction evaluation process and has been applied consistently.  We also considered our market capitalization at February 28, 2015 and March 31, 2014 and 2013, as compared to the aggregate fair values of our reporting units, to assess the reasonableness of our estimates pursuant to the discounted cash flow methodology.  Although the impairment charges recorded in the prior years were a result of utilizing management’s best estimate of fair value, the estimates and assumptions made in assessing the fair value of our reporting units and the valuation of the underlying assets and liabilities are inherently subject to significant uncertainties.  Consequently, changing rates of interest and inflation, declining sales or margins, increases in competition, changing consumer preferences, technical advances, or reductions in advertising and promotion may require additional impairments in the future. We have experienced significant declines in revenues and profitability of certain brands in the North American OTC Healthcare segment during 2015. In the past, we have experienced declines in revenues and profitability of certain brands in the North American OTC Healthcare and Household Cleaning segments. Sustained or significant future declines in revenue, profitability, other adverse changes in expected operating results, and/or unfavorable changes in other economic factors used to estimate fair value of certain brands could indicate that fair value no longer exceeds carrying value, in which case a non-cash impairment charge may be recorded in future periods.
	The aggregate fair value of our reporting units exceeded the carrying value by 45.2% with no reporting unit's fair value exceeding the carrying value by less than 10%.

In conjunction with our annual impairment analysis, we reassessed the useful lives of our intangible assets and determined that our Pediacare trade name should be reclassified to a finite-lived intangible asset with an estimated 20 year useful life. We made this determination based on the recent declines in the business and a strategic change in the focus of certain brands as we continue to prioritize our support on other significant and more recently acquired brands.
As discussed in Note 3, on October 31, 2012, we sold the Phazyme brand for $22.3 million. As a result of this divestiture, we reduced the net book value of our intangible assets by $15.6 million.
During the year ended March 31, 2013, we reclassified a portion of trademarks related to the acquired GSK brands from indefinite-lived to finite-lived intangible assets in the amount of $1.7 million.
As discussed in Note 2, on July 1, 2013, we completed the acquisition of Care Pharma. In connection with this acquisition, we allocated $31.5 million to intangible assets based on our analysis.
As discussed in Note 2, we completed two acquisitions during the year ended March 31, 2015. On September 3, 2014, we completed the acquisition of Insight and allocated $724.4 million to intangible assets based on our preliminary analysis. Additionally, on April 30, 2014, we completed the acquisition of the Hydralyte brand and allocated $73.6 million to intangible assets based on our preliminary analysis. Furthermore, on September 3, 2014 we sold one of the brands that we acquired from Insight, for which we had allocated $17.7 million to intangible assets.
Under accounting guidelines, indefinite-lived assets are not amortized, but must be tested for impairment annually, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the asset below the carrying amount.  Additionally, at each reporting period, an evaluation must be made to determine whether events and circumstances continue to support an indefinite useful life.  Intangible assets with finite lives are amortized over their respective estimated useful lives and are also tested for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable and exceeds its fair value.
On an annual basis during the fourth fiscal quarter, or more frequently if conditions indicate that the carrying value of the asset may not be recovered, management performs a review of both the values and, if applicable, useful lives assigned to intangible assets and tests for impairment.
During the fourth quarter of each fiscal year, we perform our annual impairment analysis. In prior years, we performed the analysis as of March 31. However, beginning with fiscal year 2015, we changed the date of our analysis to February 28 to better align with our annual operating plan preparation and to help facilitate our financial reporting process. We do not believe that a one-month change in the date of our analysis will significantly impact the results of our analysis or our financial statements.
We utilized the discounted cash flow method to estimate the fair value of our reporting units as part of the goodwill impairment test and the excess earnings method to estimate the fair value of our individual indefinite-lived intangible assets.   The discount rate utilized in the analyses, as well as future cash flows, may be influenced by such factors as changes in interest rates and rates of inflation.  Additionally, should the related fair values of goodwill and intangible assets be adversely affected as a result of declining sales or margins caused by competition, changing consumer preferences, technological advances or reductions in advertising and promotional expenses, we may be required to record impairment charges in the future. In addition, we considered our market capitalization at February 28, 2015, as compared to the aggregate fair values of our reporting units, to assess the reasonableness of our estimates pursuant to the discounted cash flow methodology. As a result of our analysis, we determined that the fair values exceeded the carrying values and as such, no impairment charge was recorded in 2015.
Based on our analysis, the aggregate fair value of our reporting units exceeded the carrying value by 45.2%, with no reporting unit's fair value exceeding the carrying value by less than 10%. The aggregate fair value of the indefinite-lived intangible assets exceeded the carrying value by 42.4%. Three of the individual indefinite-lived trade names exceeded their carrying values by less than 10%. The fair value of Debrox, New Skin and Ecotrin, exceed their carrying values of $76.3 million, $37.2 million and $32.9 million, by 8.3%, 9.2% and 7.9%, respectively.
The significant assumptions underpinning the fair value of Debrox include a discount rate of 10%, coupled with modest revenue growth, and advertising and promotion investments that are in line with historical performance. A decrease in the annual cash flow of approximately 7.7% compared to the projected cash flow utilized in our analysis, or an increase in the discount rate of approximately 62 basis points could result in the carrying value of our trade name exceeding its fair value, resulting in an impairment charge.
The significant assumptions supporting the fair value of New Skin and Ecotrin, include a discount rate of 10% and cash flow projections that assume stabilizing revenue declines followed by modest revenue growth. Gross margin and advertising and promotion investments behind the brands are expected to be consistent with historic trends. Continued revenue declines in each of the brands, or changes in assumptions utilized in our quantitative indefinite lived asset impairment analysis may result in the fair value no longer exceed their carrying values. For example, a decrease in the annual cash flow of approximately 8.4% and 7.3%, for New Skin and Ecotrin, respectively, compared to the projected cash flow utilized in our analysis, or an increase in the discount rate of approximately 77 and 72 basis points, respectively, could result in the carrying value of our trade name exceeding its fair value, resulting in an impairment charge. We will continue to review our results against forecasts and assess our assumptions to ensure they continue to be appropriate.
Additionally, certain of our North American OTC Healthcare and Household Cleaning brands, have experienced recent declines in revenues and profitability. While the fair value of these reporting units exceeds the carrying value by more than 10%, should such revenue declines continue, the fair value of the corresponding reporting units may no longer exceed their carrying value and we would be required to record an impairment charge.
Revenues from our Pediacare brand have declined significantly as compared to the corresponding periods in the prior year, due primarily to competition in the category, including new product introductions and lost distribution. Although we had expected revenues to decline with the return to the market of competing products, such declines have been steeper than expected. As a result, we performed an interim impairment analysis during our third quarter ended December 31, 2014 and concluded that no impairment existed. Additionally, in conjunction with a strategic review of our brands during the fourth quarter ended March 31, 2015 and our annual impairment review, we have reassessed the useful life of the Pediacare brand as of February 28, 2015 and determined it to be 20 years.
See Part II, Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" under the heading "Critical Accounting Policies" for a further discussion on the assumptions used in our impairment analysis. Furthermore, we completed our annual test for impairment of intangible assets during the fourth quarter of each of the years presented and did not record an impairment charge, as facts and circumstances indicated that the fair values of each intangible asset exceeded its carrying value. Adverse changes in the expected operating results and/or unfavorable changes in other economic factors used to estimate fair values of these specific brands could result in a non-cash impairment charge in the future.
The weighted average remaining life for finite-lived intangible assets at March 31, 2015 was approximately 14.6 years and the amortization expense for the year ended March 31, 2015 was $13.0 million. At March 31, 2015, finite-lived intangible assets are expected to be amortized over their estimated useful life, which ranges from a period of 10 to 30 years, and the estimated amortization expense for each of the five succeeding years and periods thereafter is as follows (in thousands):
Year Ending March 31,
2016	17,868

Sale of asset
Historically, we received royalty income from the licensing of the name of certain of our brands in geographic areas or markets in which we do not directly compete. We have had a royalty agreement for our Comet brand for several years, which included an option on behalf of the licensee to purchase the rights in certain geographic areas and markets in perpetuity. In December 2014, we amended the agreement to allow the licensee to buy out a portion of the agreement early, but retaining the remaining stream of royalty payments. In December, in connection with this amendment, we sold rights to use of the Comet brand in certain Eastern European countries to a third-party licensee and received $10.0 million as a partial early buyout. As a result, we recorded a gain on sale of $1.1 million, and reduced the carrying value of our intangible assets and goodwill. The licensee will continue to make quarterly payments at least through June 30, 2016 of approximately $1.0 million. The licensee has the option to purchase the remaining territories and markets, as defined in the agreement, at any time after July 1, 2016.

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt
	2012 Senior Notes:
	On January 31, 2012, Prestige Brands, Inc. (the "Borrower") issued $250.0 million of senior unsecured notes at par value, with an interest rate of 8.125% and a maturity date of February 1, 2020 (the "2012 Senior Notes"). The Borrower may earlier redeem some or all of the 2012 Senior Notes at redemption prices set forth in the indenture governing the 2012 Senior Notes. The 2012 Senior Notes are guaranteed by Prestige Brands Holdings, Inc. and certain of its domestic 100% owned subsidiaries, other than the Borrower. Each of these guarantees is joint and several. There are no significant restrictions on the ability of any of the guarantors to obtain funds from their subsidiaries or to make payments to the Borrower or the Company. In connection with the 2012 Senior Notes offering, we incurred $12.6 million of costs, which were capitalized as deferred financing costs and are being amortized over the term of the 2012 Senior Notes.
	2012 Term Loan and 2012 ABL Revolver:
	On January 31, 2012, the Borrower also entered into a new senior secured credit facility, which consists of (i) a $660.0 million term loan facility (the “2012 Term Loan”) with a 7-year maturity and (ii) a $50.0 million asset-based revolving credit facility (the “2012 ABL Revolver”) with a 5-year maturity. In subsequent years, we have utilized portions of our accordion feature to increase the amount of our borrowing capacity under the 2012 ABL Revolver by $85.0 million to $135.0 million and reduced our borrowing rate on the 2012 ABL Revolver by 0.25%. The 2012 Term Loan was issued with an original issue discount of 1.5% of the principal amount thereof, resulting in net proceeds to the Borrower of $650.1 million. In connection with these loan facilities, we incurred $20.6 million of costs, which were capitalized as deferred financing costs and are being amortized over the terms of the facilities. The 2012 Term Loan is unconditionally guaranteed by Prestige Brands Holdings, Inc. and certain of its domestic 100% owned subsidiaries, other than the Borrower. Each of these guarantees is joint and several. There are no significant restrictions on the ability of any of the guarantors to obtain funds from their subsidiaries or to make payments to the Borrower or the Company.
	On February 21, 2013, the Borrower entered into Amendment No. 1 (the "Term Loan Amendment No. 1") to the 2012 Term Loan. Term Loan Amendment No. 1 provided for the refinancing of all of the Borrower's existing Term B Loans with new Term B-1 Loans (the "Term B-1 Loans"). The interest rate on the Term B-1 Loans under the Term Loan Amendment No. 1 was based, at the Borrower's option, on a LIBOR rate plus a margin of 2.75% per annum, with a LIBOR floor of 1.00%, or an alternate base rate, with a floor of 2.00%, plus a margin. The new Term B-1 Loans mature on the same date as the Term B Loans' original maturity date.  In addition, Term Loan Amendment No. 1 provided the Borrower with certain additional capacity to prepay subordinated debt, the 2012 Senior Notes and certain other unsecured indebtedness permitted to be incurred under the credit agreement governing the 2012 Term Loan and 2012 ABL Revolver. In connection with Term Loan Amendment No. 1, during the fourth quarter ended March 31, 2013, we recognized a $1.4 million loss on the extinguishment of debt.
	On September 3, 2014, the Borrower entered into Amendment No. 2 ("Term Loan Amendment No. 2") to the 2012 Term Loan. Term Loan Amendment No. 2 provides for (i) the creation of a new class of Term B-2 Loans under the 2012 Term Loan (the "Term B-2 Loans") in an aggregate principal amount of $720.0 million, (ii) increased flexibility under the credit agreement governing the 2012 Term Loan and 2012 ABL Revolver, including additional investment, restricted payment and debt incurrence flexibility and financial maintenance covenant relief, and (iii) an interest rate on (x) the Term B-1 Loans that is based, at the Borrower’s option, on a LIBOR rate plus a margin of 3.125% per annum, with a LIBOR floor of 1.00%, or an alternate base rate, with a floor of 2.00%, plus a margin, and (y) the Term B-2 Loans that is based, at the Borrower’s option, on a LIBOR rate plus a margin of 3.50% per annum, with a LIBOR floor of 1.00%, or an alternate base rate, with a floor of 2.00%, plus a margin (with a margin step-down to 3.25% per annum, based upon achievement of a specified secured net leverage ratio).
	The 2012 Term Loan, as amended, bears interest at a rate per annum equal to an applicable margin plus, at the Borrower's option, either (i) a base rate determined by reference to the highest of (a) the Federal Funds rate plus 0.50%, (b) the prime rate of Citibank, N.A., (c) the LIBOR rate determined by reference to the cost of funds for U.S. dollar deposits for an interest period of one month, adjusted for certain additional costs, plus 1.00% and (d) a floor of 2.00% or (ii) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing, adjusted for certain additional costs, with a floor of 1.00%. For the year ended March 31, 2015, the average interest rate on the 2012 Term Loan was 5.3%.
	Under the 2012 Term Loan, we were originally required to make quarterly payments each equal to 0.25% of the original principal amount of the 2012 Term Loan, with the balance expected to be due on the seventh anniversary of the closing date. However, since we have previously made significant optional payments that exceeded all of our required quarterly payments, we will not be required to make another payment until the maturity date of January 31, 2019.
	On September 3, 2014, the Borrower entered into Amendment No. 3 (“ABL Amendment No. 3”) to the 2012 ABL Revolver. ABL Amendment No. 3 provided for (i) a $40.0 million increase in revolving commitments under the 2012 ABL Revolver and (ii) increased flexibility under the credit agreement governing the 2012 Term Loan and 2012 ABL Revolver, including additional investment, restricted payment and debt incurrence flexibility. Borrowings under the 2012 ABL Revolver, as amended, bear interest at a rate per annum equal to an applicable margin, plus, at the Borrower's option, either (i) a base rate determined by reference to the highest of (a) the Federal Funds rate plus 0.50%, (b) the prime rate of Citibank, N.A., and (c) the LIBOR rate determined by reference to the cost of funds for U.S. dollar deposits for an interest period of one month, adjusted for certain additional costs, plus 1.00% or (ii) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing, adjusted for certain additional costs. The initial applicable margin for borrowings under the 2012 ABL Revolver is 1.75% with respect to LIBOR borrowings and 0.75% with respect to base-rate borrowings. The applicable margin for borrowings under the 2012 ABL Revolver may be increased to 2.00% or 2.25% for LIBOR borrowings and 1.00% or 1.25% for base-rate borrowings, depending on average excess availability under the 2012 ABL Revolver during the prior fiscal quarter. In addition to paying interest on outstanding principal under the 2012 ABL Revolver, we are required to pay a commitment fee to the lenders under the 2012 ABL Revolver in respect of the unutilized commitments thereunder. The initial commitment fee rate is 0.50% per annum. The commitment fee rate will be reduced to 0.375% per annum at any time when the average daily unused commitments for the prior quarter is less than a percentage of total commitments by an amount set forth in the credit agreement covering the 2012 ABL Revolver. We may voluntarily repay outstanding loans under the 2012 ABL Revolver at any time without a premium or penalty. For the year ended March 31, 2015, the average interest rate on the amounts borrowed under the 2012 ABL Revolver was 2.8%.
	2013 Senior Notes:
	On December 17, 2013, the Borrower issued $400.0 million of senior unsecured notes, with an interest rate of 5.375% and a maturity date of December 15, 2021 (the "2013 Senior Notes"). The Borrower may redeem some or all of the 2013 Senior Notes at redemption prices set forth in the indenture governing the 2013 Senior Notes. The 2013 Senior Notes are guaranteed by Prestige Brands Holdings, Inc. and certain of its 100% domestic owned subsidiaries, other than the Borrower. Each of these guarantees is joint and several. There are no significant restrictions on the ability of any of the guarantors to obtain funds from their subsidiaries or to make payments to the Borrower or the Company. In connection with the 2013 Senior Notes offering, we incurred $7.2 million of costs, which were capitalized as deferred financing costs and are being amortized over the term of the 2013 Senior Notes.
	Redemptions and Restrictions:
	At any time prior to February 1, 2016, we may redeem the 2012 Senior Notes in whole or in part at a redemption price equal to 100% of the principal amount of the notes redeemed, plus a "make-whole premium" calculated as set forth in the indenture governing the 2012 Senior Notes, together with accrued and unpaid interest, if any, to the date of redemption. On or after February 1, 2016, we may redeem the 2012 Senior Notes in whole or in part at redemption prices set forth in the indenture governing the 2012 Senior Notes. In addition, at any time prior to February 1, 2015, we could redeem up to 35% of the aggregate principal amount of the 2012 Senior Notes at a redemption price equal to 108.125% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date, with the net cash proceeds of certain equity offerings, provided that certain conditions were met. Subject to certain limitations, in the event of a change of control, as defined in the indenture governing the 2012 Senior Notes, the Borrower will be required to make an offer to purchase the 2012 Senior Notes at a price equal to 101% of the aggregate principal amount of the 2012 Senior Notes repurchased, plus accrued and unpaid interest, if any, to the date of repurchase.
	At any time prior to December 15, 2016, we may redeem the 2013 Senior Notes in whole or in part at a redemption price equal to 100% of the principal amount of notes redeemed, plus an applicable "make-whole premium" calculated as set forth in the indenture governing the 2013 Senior Notes, together with accrued and unpaid interest, if any, to the date of redemption. On or after December 15, 2016, we may redeem some or all of the 2013 Senior Notes at redemption prices set forth in the indenture governing the 2013 Senior Notes. In addition, at any time prior to December 15, 2016, we may redeem up to 35% of the aggregate principal amount of the 2013 Senior Notes at a redemption price equal to 105.375% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date, with the net cash proceeds of certain equity offerings, provided that certain conditions are met. Subject to certain limitations, in the event of a change of control, as defined in the indenture governing the 2013 Senior Notes, the Borrower will be required to make an offer to purchase the 2013 Senior Notes at a price equal to 101% of the aggregate principal amount of the 2013 Senior Notes repurchased, plus accrued and unpaid interest, if any, to the date of repurchase.
	The indentures governing the 2012 Senior Notes and the 2013 Senior Notes contain provisions that restrict us from undertaking specified corporate actions, such as asset dispositions, acquisitions, dividend payments, repurchases of common shares outstanding, changes of control, incurrences of indebtedness, issuance of equity, creation of liens, making of loans and transactions with affiliates. Additionally, the credit agreement with respect to the 2012 Term Loan and the 2012 ABL Revolver and the indentures governing the 2012 Senior Notes and the 2013 Senior Notes contain cross-default provisions, whereby a default pursuant to the terms and conditions of certain indebtedness will cause a default on the remaining indebtedness under the credit agreement governing the 2012 Term Loan and the 2012 ABL Revolver and the indentures governing the 2012 Senior Notes and the 2013 Senior Notes. At March 31, 2015, we were in compliance with the covenants under our long-term indebtedness.
	At March 31, 2015, we had an aggregate of $28.6 million of unamortized debt issuance costs and $4.9 million of unamortized debt discount, the total of which is comprised of $8.7 million related to the 2012 Senior Notes, $6.2 million related to the 2013 Senior Notes, $17.4 million related to the 2012 Term Loan, and $1.2 million related to the 2012 ABL Revolver.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	As we deem appropriate, we may from time to time utilize derivative financial instruments to mitigate the impact of changing interest rates associated with our long-term debt obligations or other derivative financial instruments. While we have utilized derivative financial instruments in the past, we did not have any significant derivative financial instruments outstanding at March 31, 2015, 2014 or 2013. We have not entered into derivative financial instruments for trading purposes; all of our derivatives were over-the-counter instruments with liquid markets.
	For certain of our financial instruments, including cash, accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their respective fair values due to the relatively short maturity of these amounts.
	The Fair Value Measurements and Disclosures topic of the FASB ASC 820 requires fair value to be determined based on the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market assuming an orderly transaction between market participants. The Fair Value Measurements and Disclosures topic established market (observable inputs) as the preferred source of fair value, to be followed by the Company's assumptions of fair value based on hypothetical transactions (unobservable inputs) in the absence of observable market inputs. Based upon the above, the following fair value hierarchy was created:
	Level 1 - Quoted market prices for identical instruments in active markets;
	Level 2 - Quoted prices for similar instruments in active markets, as well as quoted prices for identical or similar instruments in markets that are not considered active; and
	Level 3 - Unobservable inputs developed by the Company using estimates and assumptions reflective of those that would be utilized by a market participant.
	The market values have been determined based on market values for similar instruments adjusted for certain factors. As such, the Term B-1 Loans, Term B-2 Loans, the 2013 Senior Notes, the 2012 Senior Notes, and the 2012 ABL Revolver are measured in Level 2 of the above hierarchy. At March 31, 2015 and 2014, we did not have any assets or liabilities measured in Level 1 or 3. During 2015, 2014 and 2013, there were no transfers of assets or liabilities between Levels 1, 2 and 3.
	At March 31, 2015 and 2014, the carrying value of our 2013 Senior Notes was $400.0 million and $400.0 million, respectively. At March 31, 2015 and 2014, the fair value of our 2013 Senior Notes was $405.0 million and $408.5 million, respectively.
	At March 31, 2015 and 2014, the carrying value of our 2012 Senior Notes was $250.0 million and $250.0 million, respectively. The fair value of our 2012 Senior Notes was $268.1 million and $280.6 million at March 31, 2015 and 2014, respectively.
	At March 31, 2015 and 2014, the carrying value of the Term B-1 Loans was $217.5 million and $287.5 million, respectively. The fair value of the Term B-1 Loans was $218.0 million and $288.9 million at March 31, 2015 and 2014, respectively.
	At March 31, 2015, the carrying value of the Term B-2 Loans was $660.0 million. The fair value of the Term B-2 Loan was $662.5 million at March 31, 2015. Because the Term B-2 Loans were entered into on September 3, 2014, there were no outstanding loan balances as of March 31, 2014.
	At March 31, 2015, the carrying value and fair value of the 2012 ABL Revolver was $66.1 million and $65.7 million, respectively. There were no outstanding borrowings under the 2012 ABL Revolver at March 31, 2014.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-based Compensation	Share-Based Compensation
	In connection with our initial public offering, the Board of Directors adopted the 2005 Long-Term Equity Incentive Plan (the “Plan”), which provides for grants, up to a maximum of 5.0 million shares of restricted stock, stock options, restricted stock units and other equity-based awards.  In June 2014, the Board of Directors approved, and in July 2014, the stockholders ratified, an increase of an additional 1.8 million shares of our common stock for issuance thereunder and increased the maximum number of shares subject to stock options that may be awarded to any one participant under the Plan during any 12-month period from 1 million to 2.5 million shares and extended the term of the Plan by 10 years, to February 2025. Directors, officers and other employees of the Company and its subsidiaries, as well as others performing services for the Company, are eligible for grants under the Plan.
	During 2015, pre-tax share-based compensation costs charged against income and the related income tax benefit recognized were $6.9 million and $1.9 million, respectively.
	During 2014, pre-tax share-based compensation costs charged against income and the related income tax benefit recognized were $5.1 million and $1.5 million, respectively.
	During 2013, pre-tax share-based compensation costs charged against income and the related income tax benefit recognized were $3.8 million and $1.2 million, respectively.
	Restricted Shares
	Restricted shares granted to employees under the Plan generally vest in three to five years, primarily upon the attainment of certain time vesting thresholds, and may also be contingent on the attainment of certain performance goals of the Company, including revenue and earnings before income taxes, depreciation and amortization targets.  The restricted share awards provide for accelerated vesting if there is a change of control, as defined in the Plan.   The restricted stock units granted to employees generally vest in their entirety on the three-year anniversary of the date of the grant. Termination of employment prior to vesting will result in forfeiture of the restricted stock units. The restricted stock units granted to directors will vest in their entirety one year after the date of grant so long as the membership on the Board of Directors continues through the vesting date, with the settlement in common stock to occur on the earliest of the director's death, disability or six-month anniversary of the date on which the director's Board membership ceases for reasons other than death or disability. Upon vesting, the units will be settled in shares of our common stock.
	On May 9, 2012, the Compensation Committee of our Board of Directors granted 111,152 restricted stock units to certain executive officers and employees under the Plan, which will vest 33.3% per year over three years. On June 29, 2012, the Compensation Committee of our Board of Directors granted 12,652 restricted stock units to the independent members of the Board of Directors under the Plan. On August 6, 2012, the Compensation Committee of the Board of Directors granted 5,109 restricted stock units to Matthew M. Mannelly, our President and CEO, under the Plan. On May 14, 2013, the Compensation Committee of our Board of Directors granted 113,637 restricted stock units to certain executive officers and employees under the Plan. Of those grants, 55,637 restricted stock units vest in their entirety on the three-year anniversary of the date of grant, and 58,000 restricted stock units vest 33.3% per year over three years. On July 29, 2013, the Compensation Committee of the Board of Directors granted 7,004 restricted stock units to the independent members of the Board of Directors under the Plan. On November 5, 2013, the Compensation Committee of our Board of Directors granted 6,000 restricted stock units to certain employees under the Plan, which will vest 33.3% per year over three years. On May 12, 2014, the Compensation Committee of our Board of Directors granted 96,638 restricted stock units to certain executive officers and employees under the Plan. Of those grants, 75,638 restricted stock units vest in their entirety on the three-year anniversary of the date of grant and 21,000 restricted stock units vest 33.3% per year over three years. On August 5, 2014, the Compensation Committee of our Board of Directors granted 7,796 restricted stock units to the independent members of the Board of Directors under the Plan. On August 14, 2014, pursuant to his employment agreement, the Compensation Committee of the Board of Directors granted 2,489 restricted stock units to Thomas Hochuli, our Vice-President of Operations, under the Plan.
	The fair value of the restricted stock units is determined using the closing price of our common stock on the day of the grant. The weighted-average grant-date fair value during 2015, 2014, and 2013 was $33.33, $30.19 and $13.59, respectively.
	A summary of the Company’s restricted shares granted under the Plan is presented below:

	Options
	The Plan provides that the exercise price of options granted shall be no less than the fair market value of the Company's common stock on the date the options are granted.  Options granted have a term of no greater than ten years from the date of grant and vest in accordance with a schedule determined at the time the option is granted, generally three to five years.  The option awards provide for accelerated vesting in the event of a change in control, as defined in the Plan. Termination of employment prior to vesting will result in forfeiture of the unvested stock options. Vested stock options will remain exercisable by the employee after termination, subject to the terms of the Plan.
	The fair value of each option award is estimated on the date of grant using the Black-Scholes Option Pricing Model that uses the assumptions noted in the table below.  Expected volatilities are based on the historical volatility of our common stock and other factors, including the historical volatilities of comparable companies.  We use appropriate historical data, as well as current data, to estimate option exercise and employee termination behaviors.  Employees that are expected to exhibit similar exercise or termination behaviors are grouped together for the purposes of valuation.  The expected terms of the options granted are derived from our historical experience, management’s estimates, and consideration of information derived from the public filings of companies similar to us, and represent the period of time that options granted are expected to be outstanding.  The risk-free rate represents the yield on U.S. Treasury bonds with a maturity equal to the expected term of the granted options.
	On May 9, 2012, the Compensation Committee of our Board of Directors granted stock options to acquire 422,962 shares of our common stock to certain executive officers and employees under the Plan. These stock options were granted at an exercise price of $13.24 per share, which is equal to the closing price for our common stock on the date of the grant. On August 6, 2012, the Compensation Committee of the Board of Directors granted stock options to acquire 21,978 shares of our common stock to Matthew M. Mannelly. These stock options were granted at an exercise price of $15.66 per share, which is equal to the closing price for our common stock on the date of grant. The stock options will vest 33.3% per year over three years and are exercisable for up to ten years from the date of grant. On May 14, 2013, the Compensation Committee of our Board of Directors granted stock options to acquire 227,672 shares of our common stock to certain executive officers and employees under the Plan. The stock options will vest 33.3% per year over three years and are exercisable for up to ten years from the date of grant. These stock options were granted at an exercise price of $29.94 per share, which is equal to the closing price for our common stock on the date of grant. On May 12, 2014, the Compensation Committee of our Board of Directors granted stock options to acquire 307,490 shares of our common stock to certain executive officers and employees under the Plan. The stock options will vest 33.3% per year over three years and are exercisable for up to ten years from the date of grant. These stock options were granted at an exercise price of $33.50 per share, which is equal to the closing price for our common stock on the date of grant. On August 14, 2014, pursuant to his employment agreement, the Compensation Committee of our Board of Directors granted stock options to acquire 10,485 shares of our common stock to Thomas Hochuli, our Vice-President of Operations, under the Plan. The stock options will vest 33.3% per year over three years and are exercisable for up to ten years from the date of grant. These stock options were granted at an exercise price of $34.79 per share, which is equal to the closing price for our common stock on the date of grant. Termination of employment prior to vesting will result in forfeiture of the unvested stock options.
	The weighted-average grant-date fair values of the options granted during 2015, 2014, and 2013 were $15.95, $13.94, and $6.03, respectively.

	The aggregate intrinsic value of options exercised during 2015 was $9.3 million.
	At March 31, 2015, there were $4.9 million of unrecognized compensation costs related to nonvested share-based compensation arrangements under the Plan, based on management’s estimate of the shares that will ultimately vest.  We expect to recognize such costs over a weighted-average period of 0.9 years.  The total fair value of options and restricted stock units vested during 2015, 2014, and 2013 was $4.7 million, $3.4 million and $2.5 million, respectively.  Cash received from the exercise of stock options was $4.0 million during 2015, and we realized $2.2 million in tax benefits for the tax deductions resulting from option exercises in 2015. Cash received from the exercise of stock options was $5.9 million during 2014, and we realized $1.7 million in tax benefits for the tax deductions resulting from option exercises in 2014. Cash received from the exercise of stock options was $6.0 million during 2013, and we realized $11.3 million in tax benefits for the tax deductions from option exercises in 2013.  On August 5, 2014 at the Annual Meeting of Stockholders, the stockholders approved the proposal to amend the Plan. The amendment authorized an additional 1.8 million shares of our common stock for issuance thereunder, increased the maximum number of shares subject to stock options that may be awarded to any one participant under the Plan during any 12-month period from 1.0 million to 2.5 million shares and extended the term of the Plan by 10 years, until February 2025. At March 31, 2015, there were 3.0 million shares available for issuance under the Plan.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	We are involved from time to time in routine legal matters and other claims incidental to our business.  We review outstanding claims and proceedings internally and with external counsel as necessary to assess probability and amount of potential loss.  These assessments are re-evaluated at each reporting period and as new information becomes available to determine whether a reserve should be established or if any existing reserve should be adjusted.  The actual cost of resolving a claim or proceeding ultimately may be substantially different than the amount of the recorded reserve.  In addition, because it is not permissible under GAAP to establish a litigation reserve until the loss is both probable and estimable, in some cases there may be insufficient time to establish a reserve prior to the actual incurrence of the loss (upon verdict and judgment at trial, for example, or in the case of a quickly negotiated settlement).  We believe the resolution of routine legal matters and other claims incidental to our business, taking our reserves into account, will not have a material adverse effect on our business, financial condition, or results from operations.
	Lease Commitments
	We have operating leases for office facilities and equipment in New York, Wyoming, and other locations, which expire at various dates through fiscal 2021. We required additional office space as a result of the closing of the acquisition of Insight. Therefore, in the first quarter of fiscal 2015, we amended our existing New York office lease to include an additional 15,470 square feet beginning October 2014 and extended the expiration of the combined lease through September 2020. These amounts have been included in the table below.
	The following summarizes future minimum lease payments for our operating leases (a):

Risks and Uncertainties [Abstract]
Concentrations of Risk	Concentrations of Risk
	Our revenues are concentrated in the areas of OTC Healthcare and Household Cleaning products.  We sell our products to mass merchandisers, food and drug stores, and dollar and club stores.  During 2015, 2014, and 2013, approximately 38.2%, 38.3%, and 40.5%, respectively, of our gross revenues were derived from our five top selling brands.  One customer, Walmart, accounted for more than 10% of our gross revenues for each of the periods presented. During 2015, 2014, and 2013, Walmart accounted for approximately 18.1%, 19.5%, and 15.9%, respectively, of our gross revenues.  At March 31, 2015, approximately 23.0% and 10.5% of accounts receivable were owed by Walmart and Walgreens, respectively. Our next largest customer accounted for approximately 8.4% of our gross revenues during 2015.
	We manage product distribution in the continental United States through a third-party distribution center in St. Louis, Missouri.  A serious disruption, such as a flood or fire, to the main distribution center could damage our inventories and could materially impair our ability to distribute our products to customers in a timely manner or at a reasonable cost.  We could incur significantly higher costs and experience longer lead times associated with the distribution of our products to our customers during the time that it takes us to reopen or replace our distribution center.  As a result, any such disruption could have a material adverse effect on our business, sales and profitability.
	At March 31, 2015, we had relationships with 95 third-party manufacturers.  Of those, we had long-term contracts with 44 manufacturers that produced items that accounted for approximately 82.9% of our gross sales for 2015, compared to 24 manufacturers with long-term contracts that accounted for approximately 82.4% of gross sales in 2014.  The fact that we do not have long-term contracts with certain manufacturers means that they could cease manufacturing our products at any time and for any reason or initiate arbitrary and costly price increases, which could have a material adverse effect on our business and results from operations. Although we are in the process of negotiating long-term contracts with certain key manufacturers, we may not be able to reach agreement which could have a material adverse effect on our business.

Segment Reporting [Abstract]
Business Segments	Business Segments
	Beginning April 1, 2014, we began managing and reporting certain of our businesses separately and have therefore realigned our reportable segments to align with how we manage and evaluate the results of our business. These reportable segments consist of (i) North American OTC Healthcare, (ii) International OTC Healthcare and (iii) Household Cleaning. The results of our previously reported OTC Healthcare segment is now separated into two reporting segments, the North American OTC Healthcare segment and the International OTC Healthcare segment, largely to reflect our international expansion due to recent acquisitions. Prior year amounts were reclassified to conform to the current reportable segments discussed above. Segment information has been prepared in accordance with the Segment Reporting topic of the FASB ASC 280. We evaluate the performance of our operating segments and allocate resources to these segments based primarily on contribution margin, which we define as gross profit less advertising and promotional expenses.

	As described in Note 10, Prestige Brands Holdings, Inc., together with certain of our 100% owned subsidiaries, has fully and unconditionally guaranteed, on a joint and several basis, the obligations of Prestige Brands, Inc. (a 100% owned subsidiary of the Company) set forth in the indentures governing the 2013 Senior Notes and the 2012 Senior Notes, including the obligation to pay principal and interest with respect to the 2013 Senior Notes and the 2012 Senior Notes. The 100% owned subsidiaries of the Company that have guaranteed the 2013 Senior Notes and the 2012 Senior Notes are as follows: Prestige Services Corp., Prestige Brands Holdings, Inc. (a Virginia corporation), Prestige Brands International, Inc., Medtech Holdings, Inc., Medtech Products Inc., The Cutex Company, The Spic and Span Company, and Blacksmith Brands, Inc. (collectively, the "Subsidiary Guarantors"). A significant portion of our operating income and cash flow is generated by our subsidiaries. As a result, funds necessary to meet Prestige Brands, Inc.'s debt service obligations are provided in part by distributions or advances from our subsidiaries. Under certain circumstances, contractual and legal restrictions, as well as the financial condition and operating requirements of our subsidiaries, could limit Prestige Brands, Inc.'s ability to obtain cash from our subsidiaries for the purpose of meeting our debt service obligations, including the payment of principal and interest on the 2013 Senior Notes and the 2012 Senior Notes. Although holders of the 2013 Senior Notes and the 2012 Senior Notes will be direct creditors of the guarantors of the 2013 Senior Notes and the 2012 Senior Notes by virtue of the guarantees, we have indirect subsidiaries located primarily in the United Kingdom, the Netherlands and Australia (collectively, the "Non-Guarantor Subsidiaries") that have not guaranteed the 2013 Senior Notes or the 2012 Senior Notes, and such subsidiaries will not be obligated with respect to the 2013 Senior Notes or the 2012 Senior Notes. As a result, the claims of creditors of the Non-Guarantor Subsidiaries will effectively have priority with respect to the assets and earnings of such companies over the claims of the holders of the 2013 Senior Notes and the 2012 Senior Notes.
	Presented below are supplemental Condensed Consolidating Balance Sheets as of March 31, 2015 and 2014 and Condensed Consolidating Income and Comprehensive Income Statements and Condensed Consolidating Statements of Cash Flows for each year in the three year period ended March 31, 2015. Such consolidating information includes separate columns for:
	a)  Prestige Brands Holdings, Inc., the parent,
	b)  Prestige Brands, Inc., the Issuer or the Borrower,
	c)  Combined Subsidiary Guarantors,
	d)  Combined Non-Guarantor Subsidiaries, and
	e)  Elimination entries necessary to consolidate the Company and all of its subsidiaries.
	The Condensed Consolidating Financial Statements are presented using the equity method of accounting for investments in our 100% owned subsidiaries. Under the equity method, the investments in subsidiaries are recorded at cost and adjusted for our share of the subsidiaries' cumulative results of operations, capital contributions, distributions and other equity changes. The elimination entries principally eliminate investments in subsidiaries and intercompany balances and transactions. The financial information in this footnote should be read in conjunction with the Consolidated Financial Statements presented and other notes related thereto contained in this Annual Report on Form 10-K for the fiscal year ended March 31, 2015.

Subsequent Events	Subsequent Events
	Debt Refinancing:
	On May 8, 2015, the Borrower entered into Amendment No. 3 (the "Term Loan Amendment No. 3") to the 2012 Term Loan. Term Loan Amendment No. 3 provides for (i) the creation of a new class of Term B-3 Loans under the 2012 Term Loan (the "Term B-3 Loans") in an aggregate principal amount of $852.5 million, which combined the current outstanding balances of the Term B-1 Loans of $207.5 million and the Term B-2 Loan of $645.0 million, (ii) increased flexibility under the credit agreement governing the 2012 Term Loan, including additional investment, restricted payment, and debt incurrence flexibility and financial maintenance covenant relief, and (iii) an interest rate on the Term B-3 Loans that is based, at the Borrower’s option, on a LIBOR rate plus a margin of 2.75% per annum, with a LIBOR floor of 0.75%, or an alternate base rate, with a floor of 1.75%, plus a margin (with a margin step-down to 3.25% per annum, based upon achievement of a specified secured net leverage ratio). The maturity date remains the same as the Term B-2 Loans original maturity date of September 3, 2021. In May 2015, the Borrower also entered into negotiations for Amendment No. 4 (“ABL Amendment No. 4”) to the 2012 ABL Revolver. ABL Amendment No. 4 provides for (i) a $35.0 million increase in the accordion feature under the 2012 ABL Revolver and (ii) increased flexibility under the credit agreement governing the 2012 ABL Revolver, including additional investment, restricted payment, and debt incurrence flexibility and financial maintenance covenant relief and (iii) extends the maturity date to 5 years from the closing date. We expect to close this transaction in the first quarter of fiscal 2016.
	Share based compensation:
	On May 11, 2015, the Compensation Committee of our Board of Directors granted 185,904 shares of restricted common stock units and stock options to acquire 186,302 shares of our common stock to certain executive officers and employees under the Plan. 163,404 shares of restricted common stock units vest in their entirety on the three-year anniversary of the date of grant and 22,500 shares of restricted common stock units vest 33.3% per year over three years. Upon vesting, the units will be settled in shares of our common stock. The stock options will vest 33.3% per year over three years and are exercisable for up to ten years from the date of grant. These stock options were granted at an exercise price of $41.44 per share, which is equal to the closing price for our common stock on the day of the grant. Termination of employment prior to vesting will result in forfeiture of the unvested restricted common stock units and the unvested stock options. Vested stock options will remain exercisable by the employee after termination, subject to the terms of the Plan.
	Election of Director:
	On May 11, 2015, James M. Jenness, retired Chairman of the Board and CEO of the Kellogg Company, was elected to the Company's board of directors. Mr. Jenness, 68, served as Chairman of the Board of Kellogg Company, a producer of cereal and convenience foods, from February 2005 to June 2014, and as Chief Executive Officer from 2004-2006. He has served as a director of Kellogg since 2007 and as a director of Kimberly-Clark Corporation, a producer of personal care products, since 2007. His background also includes serving as Chief Executive Officer of Integrated Merchandising Systems, LLC, a retail promotion and merchandising company, and a 22 year career with Leo Burnett Company, Inc., the global advertising agency, where he last served as Vice Chairman and Chief Operating Officer.
	Chief Executive Officer Retirement:
	On April 22, 2015, we announced that Matthew M. Mannelly, our President and Chief Executive Officer and member of the Board of Directors, will retire effective June 1, 2015. In conjunction with his retirement, the Board of Directors has accelerated the vesting of his previously unvested restricted stock units and stock options and we expect to record additional stock based compensation of approximately $0.8 million associated with this acceleration. Following his retirement, and effective June 1, 2015, the Board of Directors has appointed Ron Lombardi, our current Chief Financial Officer, to succeed Mr. Mannelly as President and Chief Executive Officer and as a member of the Board of Directors. The company has commenced a search for a new Chief Financial Officer, and Mr. Lombardi will also remain as Chief Financial Officer until his successor is elected.

Business and Basis of Presentation (Policies)	12 Months Ended
	Mar. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation
	Our Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").  All significant intercompany transactions and balances have been eliminated in consolidation.  Our fiscal year ends on March 31st of each year.  References in these Consolidated Financial Statements or notes to a year (e.g., “2015”) mean our fiscal year ended on March 31st of that year.
Reclassification	Reclassification
	We revised the classification of certain promotional expenses that were incurred in the prior year to correctly present the amounts as a reduction to net sales. The amounts were not material to any of the periods presented.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period.  Although these estimates are based on our knowledge of current events and actions that we may undertake in the future, actual results could differ from those estimates.  As discussed below, our most significant estimates include those made in connection with the valuation of intangible assets, stock-based compensation, fair value of debt, sales returns and allowances, trade promotional allowances and inventory obsolescence, and the recognition of income taxes using an estimated annual effective tax rate.
Cash and Cash Equivalents	Cash and Cash Equivalents
	We consider all short-term deposits and investments with original maturities of three months or less to be cash equivalents.  Substantially all of our cash is held by a large regional bank with headquarters in California.  We do not believe that, as a result of this concentration, we are subject to any unusual financial risk beyond the normal risk associated with commercial banking relationships.
Accounts Receivable	Accounts Receivable
	We extend non-interest-bearing trade credit to our customers in the ordinary course of business.  We maintain an allowance for doubtful accounts receivable based upon historical collection experience and expected collectability of the accounts receivable.  In an effort to reduce credit risk, we (i) have established credit limits for all of our customer relationships, (ii) perform ongoing credit evaluations of customers’ financial condition, (iii) monitor the payment history and aging of customers’ receivables, and (iv) monitor open orders against an individual customer’s outstanding receivable balance.
Inventories	Inventories
	Inventories are stated at the lower of cost or market value, where cost is determined by using the first-in, first-out method.  We reduce inventories for the diminution of value resulting from product obsolescence, damage or other issues affecting marketability, equal to the difference between the cost of the inventory and its estimated market value.  Factors utilized in the determination of estimated market value include (i) current sales data and historical return rates, (ii) estimates of future demand, (iii) competitive pricing pressures, (iv) new product introductions, (v) product expiration dates, and (vi) component and packaging obsolescence.
Property and Equipment	Property and Equipment
	Property and equipment are stated at cost and are depreciated using the straight-line method based on the following estimated useful lives:
		Years
	Machinery	5
	Computer equipment and software	3
	Furniture and fixtures	7
	Leasehold improvements	*
	*Leasehold improvements are amortized over the lesser of the lease term or the estimated useful life of the related asset.
	Expenditures for maintenance and repairs are charged to expense as incurred.  When an asset is sold or otherwise disposed of, we remove the cost and associated accumulated depreciation from the accounts and recognize the resulting gain or loss in the Consolidated Statements of Income and Comprehensive Income.
	Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.  An impairment loss is recognized if the carrying amount of the asset exceeds its fair value.
Goodwill	Goodwill
	The excess of the purchase price over the fair market value of assets acquired and liabilities assumed in purchase business combinations is classified as goodwill.  Goodwill is not amortized, although the carrying value is tested for impairment at least annually in the fourth fiscal quarter of each year, or more frequently if events or changes in circumstances indicate that the asset may be impaired.  Goodwill is tested for impairment at the product group level, which is one level below the operating segment level.
Intangible Assets	Intangible Assets
	Intangible assets, which are comprised primarily of trademarks, are stated at cost less accumulated amortization.  For intangible assets with finite lives, amortization is computed using the straight-line method over estimated useful lives, typically ranging from 10 to 30 years.
	Indefinite-lived intangible assets are tested for impairment at least annually in the fourth fiscal quarter of each year, or more frequently if events or changes in circumstances indicate that the asset may be impaired.  Intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts exceed their fair values and may not be recoverable.  An impairment loss is recognized if the carrying amount of the asset exceeds its fair value.
Deferred Financing Costs	Deferred Financing Costs
	We have incurred debt origination costs in connection with the issuance of long-term debt.  These costs are capitalized as deferred financing costs and amortized over the term of the related debt using the effective interest method.
Revenue Recognition	Revenue Recognition
	We recognize revenue when the following criteria are met: (i) persuasive evidence of an arrangement exists; (ii) the selling price is fixed or determinable; (iii) the product has been shipped and the customer takes ownership and assumes the risk of loss; and (iv) collection of the resulting receivable is reasonably assured.  We have determined that these criteria are met and the transfer of the risk of loss generally occurs when product is received by the customer and, accordingly, we recognize revenue at that time.  Provision is made for estimated discounts related to customer payment terms and estimated product returns at the time of sale based on our historical experience.
	As is customary in the consumer products industry, we participate in the promotional programs of our customers to enhance the sale of our products.  The cost of these promotional programs varies based on the actual number of units sold during a finite period of time.  These promotional programs consist of direct-to-consumer incentives, such as coupons and temporary price reductions, as well as incentives to our customers, such as allowances for new distribution, including slotting fees, and cooperative advertising.  Estimates of the costs of these promotional programs are based on (i) historical sales experience, (ii) the current promotional offering, (iii) forecasted data, (iv) current market conditions, and (v) communication with customer purchasing/marketing personnel.  We recognize the cost of such sales incentives by recording an estimate of such cost as a reduction of revenue, at the later of (a) the date the related revenue is recognized, or (b) the date when a particular sales incentive is offered. At the completion of the promotional program, the estimated amounts are adjusted to actual results.
	Due to the nature of the consumer products industry, we are required to estimate future product returns.  Accordingly, we record an estimate of product returns concurrent with recording sales, which is made after analyzing (i) historical return rates, (ii) current economic trends, (iii) changes in customer demand, (iv) product acceptance, (v) seasonality of our product offerings, and (vi) the impact of changes in product formulation, packaging and advertising.
Cost of Sales	Cost of Sales
	Cost of sales includes product costs, warehousing costs, inbound and outbound shipping costs, and handling and storage costs.
Advertising and Promotion Costs	Advertising and Promotion Costs
	Advertising and promotion costs are expensed as incurred.  Allowances for new distribution costs associated with products, including slotting fees, are recognized as a reduction of sales.  Under these new distribution arrangements, the retailers allow our products to be placed on the stores’ shelves in exchange for such fees.
Stock-based Compensation	Stock-based Compensation
	We recognize stock-based compensation by measuring the cost of services to be rendered based on the grant-date fair value of the equity award.  Compensation expense is to be recognized over the period an employee is required to provide service in exchange for the award, generally referred to as the requisite service period.
Income Taxes	Income Taxes
	Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.  A valuation allowance is established when necessary to reduce deferred tax assets to the amounts expected to be realized.
	The Income Taxes topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740 prescribes a recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.    The guidance only allows the recognition of those tax benefits that have a greater than 50% likelihood of being sustained upon examination by the various taxing authorities. As a result, we have applied a more-likely-than-not recognition threshold for all tax uncertainties.
	We are subject to taxation in the United States and various state and foreign jurisdictions.
	We classify penalties and interest related to unrecognized tax benefits as income tax expense in the Consolidated Statements of Income and Comprehensive Income.
Earnings Per Share	Earnings Per Share
	Basic earnings per share is calculated based on income available to common stockholders and the weighted-average number of shares outstanding during the reporting period.  Diluted earnings per share is calculated based on income available to common stockholders and the weighted-average number of common and potential common shares outstanding during the reporting period.  Potential common shares, composed of the incremental common shares issuable upon the exercise of stock options, stock appreciation rights and unvested restricted shares, are included in the earnings per share calculation to the extent that they are dilutive.
Recently Issued Accounting Standards	Recently Issued Accounting Standards
	In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from that carrying amount of that debt liability, consistent with debt discounts. The amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of ASU 2015-03 is not expected to have a material impact on our Consolidated Financial Statements.
	In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis. Update 2015-02 amended the process that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amendments in this update are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The adoption of ASU 2015-02 is not expected to have a material impact on our Consolidated Financial Statements.
	In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items. The amendments in this update eliminate the concept of extraordinary items in Subtopic 225-20, which required entities to consider whether an underlying event or transaction is extraordinary. However, the amendments retain the presentation and disclosure guidance for items that are unusual in nature or occur infrequently. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. The adoption of ASU 2015-01 is not expected to have a material impact on our Consolidated Financial Statements.
	In November 2014, the FASB issued ASU 2014-17, Pushdown Accounting, which clarifies whether and at what threshold an acquired entity that is a business or nonprofit activity can apply pushdown accounting in its separate financial statements. This ASU provides companies with the option to apply pushdown accounting in its separate financial statements upon the occurrence of an event in which an acquirer obtains control of the acquired entity. The election to apply pushdown accounting can be made either in the period in which the change of control occurred, or in a subsequent period. The amendments in this update were effective November 18, 2014. The adoption of ASU 2014-17 did not have a material impact on our Consolidated Financial Statements.
	In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This amendment states that in connection with preparing financial statements for each annual and interim reporting period, an entity's management should evaluate whether there are conditions or events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued, when applicable). The amendments in this update are effective for the annual reporting period beginning after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The adoption of ASU 2014-15 is not expected to have a material impact on our Consolidated Financial Statements.
	In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could Be Achieved after the Requisite Service Period, which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the new guidance does not allow for a performance target that affects vesting to be reflected in estimating the fair value of the award at the grant date. The amendments to this update are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in this update either prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We currently do not have any outstanding share-based payments with a performance target. The adoption of ASU 2014-12 is not expected to have a material impact on our Consolidated Financial Statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers - Topic 606, which supersedes the revenue recognition requirements in FASB ASC 605. The new guidance primarily states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. We are evaluating the impact of adopting this prospective guidance on our Consolidated Financial Statements.
	In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. In addition, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The amendments in this update must be applied prospectively to all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. The adoption of ASU 2014-08 is not expected to have a material impact on our Consolidated Financial Statements.
	Management has reviewed and continues to monitor the actions of the various financial and regulatory reporting agencies and is currently not aware of any other pronouncement that could have a material impact on our consolidated financial position, results of operations or cash flows.
