Selling, General and Administrative Expenses. Selling, general and administrative expenses were
Our selling, general and administrative expenses for fiscal 2012 reflects a net expense of
$3.0 million, consisting of (i) $1.3 millionof restructuring costs associated with the wind-down of our microsatellite product line, (ii) $2.6 millionof professional fees associated with a withdrawn contested proxy solicitation related to our fiscal 2011 annual meeting of stockholders, offset, in part, by (iii) a $0.9 millionbenefit relating to a change in the fair value of a contingent earn-out liability associated with our acquisition of Stampede. Excluding the net expense of $3.0 million, our selling, general and administrative expenses for fiscal 2012 would have been $84.1 million, or 19.8% of respective fiscal 2012 sales and would have decreased by $10.0 millionas compared to fiscal 2011. This decrease was primarily driven by a decrease in (i) compensation-related expenses associated with a lower level of consolidated net sales during fiscal 2012 and (ii) lower depreciation expense related to certain mobile data communications segment fixed assets fully depreciated in fiscal 2011 due to the expiration of our MTS contract. This decrease was partially offset by increased legal costs and professional fees associated with legal proceedings and other matters, including certain matters discussed in "Notes to Consolidated Financial Statements - Note (14)(b) Commitments and Contingencies - Legal Proceedings and Other Matters" included in "Part II - Item 8. - Financial Statements and Supplementary Data." Amortization of stock-based compensation expense recorded as selling, general and administrative expenses decreased to $2.7 millionin fiscal 2012 from $4.0 millionin fiscal 2011.
As a percentage of consolidated net sales, selling, general and administrative expenses were 20.5% and 15.4% for fiscal 2012 and 2011, respectively. This increase is primarily attributable to the significantly lower level of consolidated net sales during fiscal 2012 as compared to fiscal 2011.
