Total lease and rental expenses under non-cancelable operating leases extending one year or more approximated $2.4 million in 2011, $3.2 million in 2012 and $2.6 million in 2013. We were parties to contracts with ConocoPhillips through December 2013 for the supply of petroleum needle coke, our primary raw material used in the manufacture of graphite electrodes. That contract has expired and we intend to source the majority of our petroleum needle coke internally in 2014. We believe that our internal sourcing supplemented by external sourcing will be sufficient for our requirements as currently forecast. Our supply agreements contain customary terms and conditions including annual price negotiations, dispute resolution and termination provisions.
