On December 23, 2015, one of our investee companies in which we held a small equity stake, Lancope Inc., was sold to Cisco, Inc. We recognized a gain of $2,034,000 against our carrying value of $214,000 in the fourth quarter of 2015. Cash from the sale of $2,248,000 (which is included in “Other Current Assets” at December 31, 2015) was received in early January 2016. A portion of the sale proceeds is being held in escrow for eighteen months for claims that the buyer may assert against Lancope, Inc. Our portion of the escrow may be as much as $390,000; however, as there is presently no way to estimate how much, if any, of the escrow will be released to us, we have not included any provision for the receipt of any escrow funds in our current financial statements.
