Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Principles of Consolidation, Policy
The consolidated financial statements include the consolidated financial results of SPH, its wholly owned subsidiary WebFinancial Holding Corporation (“WebFinancial”), Handy & Harman Ltd ("HNH"), BNS Holding, Inc. ("BNS"), the BNS Liquidating Trust, (BNS Liquidating Trust"), DGT Holdings Corp. ("DGT"), Steel Excel Inc. ("Steel Excel") and SPH Services, Inc. ("SPH Services"). Acquired companies are presented from their dates of acquisition (see Note 3 - "Acquisitions" for information on acquisition activity). DGT’s financial statements are recorded on a two-month lag, and as a result the statement of operations for the twelve months ended December 31, 2012 includes DGT’s activity for its twelve months ended October 27, 2012. In 2011, BNS changed its fiscal year end from October 31 to December 31. The twelve months ended December 31, 2011 includes two additional months for BNS, November and December of 2010.

On August 16, 2012, DGT completed the sale of its RFI subsidiary's Power Conversion assets and operations. Also, in January 2013, HNH divested substantially all of the assets and existing operations of its Continental Industries ("Continental")business unit, a wholly-owned subsidiary of H&H. The results and operations of RFI and Continental are presented as discontinued operations in SPH's consolidated financial statements for all periods presented in this Form 10-K (see Note 4 - "Discontinued Operations").
Principles of Consolidation
The consolidated financial statements include the accounts of SPH consolidated with the accounts of its subsidiaries. Acquired companies are presented from their dates of acquisition (see Note 3 - “Acquisitions” and Note 5 - “Investments in Associated Companies”). Significant inter-company accounts and transactions have been eliminated in consolidation.
