[1] The Company has established a non-qualified deferred compensation plan for certain members of management and all non-employee directors. The Company is informally funding its obligations under the deferred compensation plan by purchasing shares in various equity, bond and money market mutual funds that are held in a "Rabbi Trust" and are restricted for payment of obligations to plan participants. The deferred compensation plan liability is included in Other Non-current Liabilities in the accompanying consolidated balance sheets.

[2] The equity investment in LoJacks French licensee, in the form of a publicly-traded common stock, is accounted for as an available-for-sale security and is valued at the quoted closing price on its market exchange. The related unrealized gains or losses are included in accumulated other comprehensive income (loss) in the stockholders equity section of the consolidated balance sheet.

[3] The Company purchased 850,100 shares of LoJack common stock in the open market in November and December 2015, prior to entering into a definitive agreement to acquire 100% of LoJacks common stock. These shares were considered trading securities and were recorded at fair value as of February 28, 2016.
