[1] The Company provides health insurance coverage to qualified union employees providing personal care services in Illinois through a Taft-Hartley multi-employer health and welfare plan under Section 302(c)(5) of the Labor Management Relations Act of 1947. The Company's insurance contributions equal the amount reimbursed by the State of Illinois. Contributions are due within five business days from the date the funds are received from the State. Amounts due of $0.3 million and $2.2 million for health insurance reimbursements and contributions were reflected in prepaid insurance and accrued insurance as of March 31, 2017 and December 31, 2016, respectively.

[2] As a condition of the sale of substantially all of the assets used in the Company's home health business to subsidiaries of LHC Group, Inc. ("LHCG") in February 2013, the Company is responsible for any adjustments to Medicare and Medicaid billings prior to the closing. In connection with an internal evaluation of the Company's billing processes, the Company discovered documentation errors in a number of claims that it had submitted to Medicare. Consistent with applicable law, the Company voluntarily remitted $1.8 million to the U.S. government in March 2014. As of March 31, 2017, the Company, using its best judgment, has estimated a total of $0.4 million for billing adjustments for 2013, 2012 and 2011 services which may be subject to Medicare audits. For the years ended December 31, 2016 and 2015, the Company reduced the indemnification reserve accrual by the amounts accrued for periods no longer subject to Medicare audits of $0.2 million and $0.4 million, respectively. This amount is reflected as a reduction in general and administrative expense of discontinued operations.

[3] Accrued severance represents amounts payable to terminated employees with employment and/or separation agreements with the Company.

[4] Accrued restructuring includes reserves for lease commitments related to the closure of three adult day services centers in Illinois during the third quarter of 2016 and unused contact center office space.
