Revision to Financial Statements[Abstract]
Revision to financial statements	3. Revision to financial statements During the year ended December 31, 2011, the Company identified historical errors relating to its tax treatment of deferred compensation obligations assumed as part of the 2003 acquisition of the Private Client Division from Canadian Imperial Bank of Commerce (“CIBC”) that affected prior periods. As a result, the Company determined the need to reestablish book basis of goodwill related to the 2003 transaction in the amount of $5.4 million. Further analysis revealed uncertain tax positions, that were inadvertently taken as a result of the errors, leading to the establishment of a reserve in the amount of $3.0 million, including accrued interest, as well as cumulative adjustments primarily related to current and deferred tax items of $2.8 million for periods prior to 2009. The Company assessed the impact of the errors, including the impact of previously disclosed out-of-period adjustments, on its prior period financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2010 and concluded that these errors were not material, individually or in the aggregate, to any of those financial statements. Although the effect of these errors was not material to any previously issued financial statements, the cumulative effect of correcting these historical errors during the fiscal year 2011 would have been material. As part of this revision process, the Company also reversed other previously disclosed out-of-period adjustments which were immaterial, and recorded them instead in the periods in which the errors originated. These revisions have no net impact on the Company’s net cash amounts provided by (used in) operating, financing or investing activities for the any of the periods previously reported, nor in the current period. The cumulative effect of the above adjustments resulted in a $9.8 million credit to opening retained earnings as of January 1, 2011. The financial statements as of March 31, 2011, included herein, have been prepared in light of the cumulative revisions above. The financial statements for all other periods affected by the revisions can continue to be relied upon, and will be revised to reflect the revisions discussed above, the next time such financial statements are included in future reports for comparative purposes.

Revision to Financial Statements[Abstract]

3. Revision to financial statements

During the year ended December 31, 2011, the Company identified historical errors relating to its tax treatment of deferred compensation obligations assumed as part of the 2003 acquisition of the Private Client Division from Canadian Imperial Bank of Commerce (“CIBC”) that affected prior periods. As a result, the Company determined the need to reestablish book basis of goodwill related to the 2003 transaction in the amount of $5.4 million. Further analysis revealed uncertain tax positions, that were inadvertently taken as a result of the errors, leading to the establishment of a reserve in the amount of $3.0 million, including accrued interest, as well as cumulative adjustments primarily related to current and deferred tax items of $2.8 million for periods prior to 2009.

The Company assessed the impact of the errors, including the impact of previously disclosed out-of-period adjustments, on its prior period financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2010 and concluded that these errors were not material, individually or in the aggregate, to any of those financial statements. Although the effect of these errors was not material to any previously issued financial statements, the cumulative effect of correcting these historical errors during the fiscal year 2011 would have been material. As part of this revision process, the Company also reversed other previously disclosed out-of-period adjustments which were immaterial, and recorded them instead in the periods in which the errors originated. These revisions have no net impact on the Company’s net cash amounts provided by (used in) operating, financing or investing activities for the any of the periods previously reported, nor in the current period. The cumulative effect of the above adjustments resulted in a $9.8 million credit to opening retained earnings as of January 1, 2011.

The financial statements as of March 31, 2011, included herein, have been prepared in light of the cumulative revisions above. The financial statements for all other periods affected by the revisions can continue to be relied upon, and will be revised to reflect the revisions discussed above, the next time such financial statements are included in future reports for comparative purposes.
