[1] 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 LoJack. These shares are considered trading securities and were recorded at fair value at the end of fiscal 2016, resulting in a gain of $1.4 million that was recorded as investment income in the consolidated statement of comprehensive income.

[2] 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. See Note 7 for additional information regarding the deferred compensation plan.
