Affiliate cash represents cash accounts maintained by joint ventures in which we participate where one or more of our external partners requested, and we agreed, that the joint venture’s cash not be commingled with other corporate cash accounts and be used only to fund the operations of those joint ventures. Self-insured captive funds represent cash held at our wholly owned insurance captive, HCS, Ltd., as discussed in Note 9, Self-Insured Risks. These funds are committed to pay third-party administrators for claims incurred and are restricted by insurance regulations and requirements. These funds cannot be used for purposes outside HCS without the permission of the Cayman Islands Monetary Authority. Paid-loss deposit funds represent cash held by third-party administrators to fund expenses and other payments related to claims.

The classification of restricted cash held by HCS as current or noncurrent depends on the classification of the corresponding claims liability. As of December 31, 2013 and 2012, all restricted cash was current.

Marketable Securities—

Restricted marketable securities at both balance sheet dates represent restricted assets held at HCS. HCS insures HealthSouth’s professional liability, workers’ compensation, and other insurance claims. These funds are committed for payment of claims incurred, and the classification of these marketable securities as current or noncurrent depends on the classification of the corresponding claims liability. As of December 31, 2013 and 2012, $42.9 million and $39.4 million, respectively, of restricted marketable securities are included in Other long-term assets in our consolidated balance sheets.

Our portfolio of marketable securities is comprised of investments in mutual funds that hold investments in a variety of industries and geographies. As discussed in Note 1, Summary of Significant Accounting Policies, “Marketable Securities,” when our portfolio includes marketable securities with unrealized losses that are not deemed to be other-than-temporarily impaired, we examine the severity and duration of the impairments in relation to the cost of the individual investments. We also consider the industry and geography in which each investment is held and the near-term prospects for a recovery in each.
