Methodology for determining whether entity is the primary beneficiary of the variable interest entity	Under the agreement, the Company obtained a majority of seats and control of Pathway’s Board of Directors. The convertible note is considered a variable interest and the Company was determined to be the primary beneficiary of Pathway.
Extent of, or lack of recourse, related to the variable interest entity	Pathway’s assets cannot be used to settle the Company’s obligations and Pathway’s creditors have no recourse to the general credit of the Company.
Disposal group, including discontinued operation, description and timing of disposal	During the six months ended September 28, 2012, the Company’s Board of Directors approved a strategic restructuring plan which includes the sale of two business units serving skilled nursing facilities and specialty dental practices. The Company’s variable interest in Pathway has been included in the disposal group as part of the restructuring plan. See Footnote 3, Discontinued Operations, for additional information on the Company’s fiscal year 2013 strategic restructuring plan and corresponding discontinued operations. The Company also holds an additional variable interest in an entity not considered material for disclosure.

A description of the facts and circumstances leading to the completed or expected disposal, and the manner and timing of that disposal. Sales of disposal groups, including those classified as components of the entity (discontinued operations), are generally expected to be completed within one year of their classification as held-for-sale.
