As a result of the rapid growth in our earnings, in 2014 we increased our dividend 25 percent, which is now 250 percent higher than when we initiated it in 2011.
The occurrence of any of these operating problems at our facilities may have a material adverse effect on the productivity and profitability of a particular manufacturing or distribution facility or on our operations as a whole, during and after the period of these operating difficulties.
Additionally, PolyOne repaid $102.3 million related to Spartech’s 7.08% senior notes due 2016, including $88.9 million of aggregated principal, $10.3 million make-whole provisions, and $3.1 million of interest payable.

These responsibilities will be addressed at regular meetings of the Board and its committees and will be monitored periodically through performance evaluations of each Board member, each Board Committee, and the Board as a whole.
The second is an estimation of a rapid transition to a low-carbon economy (a 1.5-degree scenario) of a global carbon price of $100/metric ton.
We know that this will take a lot of work and since 2050 is just around the corner, rapid action and accountability is needed.

The Director evaluation process includes self-evaluation of the Board as a whole and of each Board committee, as well as a peer evaluation.
Nicolas deferred payment of all of his annual cash retainer, as well as meeting fees, into the Deferred Compensation Plan, which amounts were invested in Company common shares, rounded up to the nearest whole share.
We determined the number of shares to be granted each quarter by dividing the applicable dollar value by the arithmetic average of the high and low stock price on the last trading day of each quarter and rounding to a whole share as partial shares are not issued.

• Continued rapid pace of innovation with 43% of our specialty platform sales from products introduced in the last five years. • Increased our dividend 20%—our fifth consecutive annual increase— and repurchased 4.5 million shares of our common stock. • Further strengthened our balance sheet by refinancing a portion of our outstanding debt, significantly lowering interest rates, extending maturities and enhancing liquidity.
The occurrence of an operating problem at our facilities (e.g., an explosion, mechanical failure, chemical spills or discharges) may have a material adverse effect on the productivity and profitability of a particular manufacturing or distribution facility or on our operations as a whole, during and after the 10 POLYONE CORPORATION period of these operating difficulties.
We used a portion of the net proceeds of the offering to pay the cash portion of the Spartech acquisition, and to repay certain Spartech debt, including the $88.9 million aggregate principal amount of its senior notes due 2016 and related interest and make-whole payments totaling $13.4 million and all outstanding amounts under its revolving credit facility.
