(e) On March 28, 2014, the Compensation Committee of the Board of Directors (the “Compensation Committee”) of Silver Spring Networks, Inc. (the “Company”) approved certain compensation actions for its executive officers, including Eric P. Dresselhuys, the Company’s Executive Vice President, Global Development, one of its named executive officers, which are required to be disclosed pursuant to this Item. Other compensation actions for Mr. Dresselhuys and the Company’s other named executive officers were made pursuant to previously disclosed plans and are not required to be disclosed under this Item.

Award Pursuant to 2013 Sales Incentive Plan

The Compensation Committee approved a cash incentive payment to Mr. Dresselhuys, under the Company’s 2013 Sales Incentive Compensation Plan (the “2013 Sales Plan”). The 2013 Sales Plan provides guidelines and eligibility for awards in amounts based on individual or sales team achievement of target performance goals, including non-GAAP revenue (billings) and bookings. Awards to participating executive officers under the 2013 Sales Plan were subject to the approval of the Compensation Committee. Under the 2013 Sales Plan, Mr. Dresselhuys was eligible to receive an incentive payment ranging from 50% to 125% of a target amount of $220,000 upon achievement of certain non-GAAP revenue (billings) and bookings performance goals, with each metric assigned a 50% weight. The Committee approved an award of $133,307 under the 2013 Sales Plan.

2014 Sales Incentive Plan

The Compensation Committee also approved the target performance goals for Mr. Dresselhuys under the Company’s 2014 Sales Incentive Plan (the “2014 Sales Plan”). The 2014 Sales Plan provides guidelines and eligibility for awards in amounts based on individual or sales team achievement of target performance goals, including non-GAAP revenue (billings) and bookings. The 2014 Sales Plan covers the 12-month period ending December 31, 2014 (the “Plan Period”). For executive officers participating in the 2014 Sales Plan, the Compensation Committee selects the specific performance goals, and the relative weighting of the performance goals, for the Plan Period, in accordance with the guidelines set forth in the 2014 Sales Plan. The Compensation Committee also establishes minimum thresholds for the performance goals during the Plan Period that must be exceeded before an award is earned by an executive officer. Awards to participating executive officers under the 2014 Sales Plan are subject to the approval of the Compensation Committee.

For 2014, Mr. Dresselhuys will be eligible to receive an incentive payment ranging from 50% to 125% of a target amount of $266,800, upon achievement of certain non-GAAP revenue (billings) and bookings performance goals, with each metric assigned a 50% weight.

Mr. Dresselhuys’ salary increase is effective April 1, 2014, and reflects his increased responsibility for leading our worldwide sales organization.
