Our 2014 minimum funding requirements are expected to be approximately $2.0 million. Our estimate of future annual contributions  is based on current funding requirements, and we believe these contributions will be sufficient to fund the plan. Expected benefit payments to eligible participants under this plan for the next five years are as follows (in thousands): We maintain five defined contribution plans (the “Defined Contribution Plans”) for the benefit of eligible employees in Canada, The Netherlands, Puerto Rico, the United Kingdom and the United States. In accordance with the terms of each plan, we and our  participating employees contribute up to specified limits and under certain plans, we may make discretionary contributions in accor- dance with the Defined Contribution Plans. For the years ended December 31, 2013, 2012 and 2011, we expensed approximately $7.1 million, $6.2 million and $5.7 million, respectively, for our contributions and our additional discretionary contributions to the  Defined Contribution Plans. We have entered into deferred compensation contracts for certain key employees. The benefits under these contracts are fully vested  and benefits are paid when the participants attain 65 years of age. The charge to expense for these deferred compensation contracts  in 2013, 2012 and 2011 was approximately $3.5 million, $1.3 million and $1.3 million, respectively. Life insurance policies with cash  surrender values have been purchased for the purpose of funding the deferred compensation contracts. We have adopted a non-qualified deferred compensation plan that allows certain highly compensated employees to defer a portion  of their salary, commission and bonus, as well as the amount of any reductions in their deferrals under the deferred compensation  plan for employees in the United States (the “Deferred Compensation Plan”), due to certain limitations imposed by the U.S. Internal  Revenue Code of 1986, as amended (the “Internal Revenue Code”). The Deferred Compensation Plan also provides for employer  contributions to be made on behalf of participants equal in amount to certain forfeitures of, and/or reductions in, employer contribu- tions that participants could have otherwise received under the Defined Contribution Plan for U.S. employees qualified under Internal  Revenue Code Section 401(k) had there not been certain limitations imposed by the Internal Revenue Code. Employer contributions  to the Deferred Compensation Plan vest ratably over a period of five years. Contributions to the plan are invested in equity and other  investment fund assets within life insurance policies, and carried on the balance sheet at fair value. A participant’s plan benefits  include the participant’s deferrals, the vested portion of the employer’s contributions, and deemed investment gains and losses  on such amounts. The benefits under these contracts are fully vested and payment of benefits generally commences as of the last  day of the month following the termination of services except that the payment of benefits for select executives generally  commences on the first working day following a six month waiting period following the date of termination. Employer contributions  to the Deferred Compensation Plan were $0.3 million, $0.3 million and $0.3 million for the years ended December 31, 2013, 2012  and 2011, respectively. Vesting in all employer contributions is accelerated upon the death of the participant or a change in control. Employer contributions  under the plans are forfeited upon a participant’s termination of employment to the extent they are not vested at that time. The Company’s only financial assets and liabilities which involve fair value measures relate to certain aspects of the Company’s benefit  plans. On a recurring basis, we use the market approach to value certain assets and liabilities at fair value at quoted prices in an active  market (Level 1) and certain assets and liabilities using significant other observable inputs (Level 2) with the assistance of a third party  specialist. We do not have any assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs  53 Deferred Compensation Arrangements Defined Contribution Plans 2014 $ 1,189 2015 $ 1,215 2016 $ 1,318 2017 $ 1,502 2018 $ 1,549 Succeeding five years  $  9,333
