MEMORANDUM OPINION AND ORDER
This matter is before the Court on cross motions for summary judgment filed by plaintiff Robert Stein ("plaintiff" or "Stein") and defendant Garen & Associates Erisa Plan ("defendant" or "the Plan"). For the reasons set forth below, defendant's motion for summary judgment is granted and plaintiff's motion for summary judgment is denied. Background*fn1
Stein was the sole shareholder and President of Garen & Associates (later Stein Garen and Associates), a tax consulting and accounting firm located in Skokie, Illinois. Stein ceased working at the firm on July 12, 2002 due to multiple sclerosis. Garen & Associates established the Plan in order to provide long term disability insurance coverage to its employees, pursuant to the terms of a group disability insurance policy ("Group Policy") issued by Unum Life Insurance Company of America ("Unum") to Garen & Associates in June 1990. The Group Policy was issued with a retroactive effective date of January 1, 1990.
Patricia Lee, a Unum employee, faxed a letter to Stein dated April 11, 1990 stating as follows:
I have faxed the material showing you how we handle income from a K-1 in determining LTD benefits.
For the past, since you did not file your taxes this way, we need a letter from you stating what your ordinary income would have been for the past 2-3 years so we could use this in our calculations should you become disabled prior to the filing of next year's tax return.
On April 16, 1990, Stein provided Ms. Lee, at Unum's Chicago, Illinois office, with a letter stating as follows:
Factoring out amortization from my Financial Statements, (amortization is an intangible non cash expense), my cash flow for the years 1987, 1988, and 1989 are as follows:
1987: $118,435.00 1988: $107,076.00 1989: $99,937.00 These amounts are net of rents received.
The Group Policy contains the following provision for calculating a Plan participant's monthly disability benefit:
To figure the amount of monthly benefit: 1. Take the lesser of:
a. 60% of the insured's basic monthly earnings; or
b. the amount of the maximum monthly benefit shown in the policy specifications; and 2. Deduct other income benefits, shown below, from this amount.
The Group Policy's provision for "other income benefits" provides for a deduction of the amount of disability benefits received under the Social Security Act. The Group Policy specifications also provide for a maximum monthly benefit in the amount of $5,000.00. The Group Policy contains the following definition of Basic Monthly Earnings ("BME"):
