Assume the IRS allows you to contribute up to $18,000 annually to your 401(k). You've decided to contribute 11% of your annual salary to the plan. Questions: 1. What is your current annual contribution? How much more money would you need to contribute to meet the maximum allowable contribution set forth by the IRS? 2. The company offers you a $.50 match for each dollar that you contribute. This match is only offered for contributions up to and including 7% of your annual salary. How much is the total company match (in dollars) based on your 11% contribution? 3. Is this a defined benefit plan or defined contribution plan? Please explain
