During 2014, 2013 and 2012, we restructured certain administrative functions and incurred $3.4 million, $8.8 million and $6.5 million, respectively, in related costs consisting principally of severance charges and, for the 2013 year, also included the write-off of certain patents.

During 2014, we incurred $12.5 million in costs associated with restructuring of executive management. These costs include severance payments, accelerated vesting of stock-based compensation awards, accrual of the present value of deferred compensation and other benefits to our then Chief Executive Officer as defined in his termination agreement; accelerated vesting of stock-based compensation awards to certain members of executive management, consulting fees and other benefits earned as further described in our Form 8-K filing on July 23, 2014.

During 2014, we incurred $4.0 million in consulting and legal costs associated with shareholder activism.

During 2014 and 2012, we incurred $0.7 million and $1.2 million, respectively, in acquisition related costs as further described in Note 16.

During 2014 and 2013, we incurred $3.4 million and $3.2 million, respectively in legal and settlement costs. Legal costs for a patent infringement claim that we settled totaled $1.9 million and $3.2 million in 2014 and 2013, respectively. The 2014 patent infringement claim costs included $0.9 million in settlement costs during the first quarter of 2014 as further described in Note 10. The remaining $1.5 million in 2014 legal costs were associated with a legal matter in which we prevailed at trial and consulting fees.

During 2012, we incurred $1.6 million in legal costs related to a contractual dispute with a former distributor. The dispute was resolved in the second quarter of 2012.

During 2013, we had a higher level of lump sum withdrawals from pension plan participants. This resulted in an acceleration of the recognition of a portion of our projected benefit obligation and we therefore recorded a pension settlement expense of $1.4 million. Refer to Note 9 for details.

During 2012, we incurred $0.7 million in charges associated with the 2011 purchase the Company's former distributor for the Nordic region of Europe.
