Assets in the Fidelity Advisor Equity Growth Account, Fidelity Advisor Growth Opportunities Account, Fidelity Advisor Balanced Account, CIGNA Charter Large Company Stock Index Fund, CIGNA Charter Growth and Income Fund, AIM Constellation Account, Dreyfus Founders Growth Account, Janus Worldwide Account, Neuberger Berman Partners Account, CIGNA Charter Small Company Stock Growth Fund, and State Street Global Advisors Intermediate Bond Account represent the Plan's share of the value of certain assets held in the insurance company's separate accounts. Such assets are stated at estimated fair value as determined by the insurance company based upon the fair value of the funds underlying assets. Income from these funds represents the Plan's share of income from the separate accounts. Assets in the CIGNA Charter Guaranteed Long-Term Fund represent the contract value, which approximates fair value, of a guaranteed investment contract held with an insurance company. The crediting interest rate and average yield for the guaranteed fund was 5.6% for 1999 and 1998. The crediting interest rate is determined semi-annually by Connecticut General Life Insurance Company (CIGNA) based upon market conditions. Participant loans are valued at the estimated fair value of the loan. All investments are participant directed. 8 9 Computer Network Technology Corporation 401(k) Salary Savings Plan NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1999 and 1998 NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Plan and Administrative Expenses All investment fees incurred with regard to the purchase and sale of investments are paid by the Plan and are netted with investment income. During 1999 and 1998, $13,154 and $19,529 of investment fees were paid by the Plan and netted with investment income. Other administrative expenses, that are not offset by forfeitures of terminated participants' non-vested amounts, are paid by the Plan Sponsor, Computer Network Technology Corporation. Net Appreciation in Fair Value of Investments Net appreciation in the fair value of investments represents the net realized gains or losses and the net unrealized appreciation or depreciation of investments. Realized gains or losses are the difference between the proceeds received and either the cost of the investment sold, determined on an average cost basis, or the fair value at the end of the previous year, whichever is applicable. Unrealized appreciation or depreciation is the change in the difference between fair value and the cost of investments or the fair value at the end of the previous year, whichever is applicable. Benefits Paid to Participants Benefits paid to participants are recorded by the Plan when paid. Use of Estimates Preparing financial statements in conformity with accounting principles generally accepted in the United States of America requires Plan management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosures of contingent assets and liabilities. Actual results could differ from those estimates. 9 10 Computer Network Technology Corporation 401(k) Salary Savings Plan NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1999 and 1998 NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Adoption of Statement of Position 99-3 The Plan has adopted Statement of Position (SOP) 99-3, Accounting for and Reporting of Certain Defined Contribution Plan Investments and Other Disclosure Matters for the plan year ended December 31, 1999. This SOP eliminates certain disclosures for participant-directed investment programs and the requirement to disclose the total number of units and net asset values per unit. The adoption of the SOP had no effect on the total net asset amounts disclosed in the financial statements. Certain reclassifications have been made to the 1998 financial statements to conform to the presentation used in 1999. NOTE B - PLAN DESCRIPTION The following description of the Plan provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General The Plan is a defined contribution plan subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan was established effective January 1, 1991 and elective deferrals were first permitted beginning July 1, 1991. During 1998, the Plan was restated, effective January 1, 1997, to incorporate all amendments and tax compliance provisions. Plan assets are held by a trustee, CG Trust Company. Eligibility All employees of Computer Network Technology Corporation (the Company) who are age eighteen or older and are scheduled to work at least 1,000 hours of service in the first year are eligible to participate in the Plan beginning on the first day of the calendar quarter following one month of employment. Employees are eligible for discretionary employer matching contributions when they become participants in the Plan, provided they are employees of the Company as of December 31. 10 11 Computer Network Technology Corporation 401(k) Salary Savings Plan NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1999 and 1998 NOTE B - PLAN DESCRIPTION - Continued Vesting Participant elective deferral contributions are 100% vested regardless of length of service. Employer match contributions are 50% vested with two years of service, 75% vested with three years of service, and 100% vested with four years of service (see Note F). Funding Policy Contributions made pursuant to participant elective deferrals are permitted up to 15% of the participant's compensation, subject to limits established by law. Participants may also make rollover contributions to the Plan. Elective deferral contribution percentages may be changed on the first day of the calendar quarter. During 1998, the Plan accepted after-tax contributions of $99,352 from participants. As of January 1, 1999, the Plan no longer accepts after-tax contributions. Matching employer contributions are at the discretion of the Plan Sponsor. The contribution is based on a matching percentage of eligible participant contributions, not to exceed a dollar amount, as determined by the employer. During 1999 and 1998, the employer match was 50% of employee contribution, not to exceed $1,000 (see note F). The participant must be employed on the last day of the Plan year to share in the employer contribution. Participants' Accounts Participants' accounts are credited with their participant contributions (elective deferral and rollover), discretionary employer matching contributions and an allocation of Plan earnings. Allocations of Plan earnings are based on participant account balances, as defined in the Plan. The benefit to which a participant is entitled is the vested portion of the participant's account. Payment of Benefits On termination of service, a participant may elect to receive a lump-sum distribution equal to the value of the participant's vested interest in his or her account, net of tax, or to rollover the entire vested portion to a qualified plan. If the participant account is not fully distributed at termination of service, an installment payment may be elected by the participant. If the participant's vested balance is greater than $5,000, the participant may also elect not to receive a distribution at the date of termination, as defined in the agreement. 11 12 Computer Network Technology Corporation 401(k) Salary Savings Plan NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1999 and 1998 NOTE B - PLAN DESCRIPTION - Continued Plan Termination Although the Plan Sponsor has no current intention of terminating the Plan, the Plan provides that upon termination, all amounts credited to a participant's account become 100% vested. Net assets of the Plan would be distributed to the participants as prescribed in the Plan agreement. Net Transfers Between Accounts and Funds Assets of the Plan are held in various accounts and funds, as defined in the Plan summary. The Plan allows participant's to direct their investments and to make transfers between these accounts and funds daily, except for the participant loan fund. Participant loan transactions are treated as transfers to/(from) the investment funds from/(to) the participant loan fund. The total of all interfund transfers between the investment accounts and funds and the participant loan fund is zero. Participant Loans The Plan allows participants to direct the investment of certain assets in their accounts by providing loans to participants. Participants may borrow from their fund accounts up to a maximum of the lesser of $50,000 or 50% of their vested account balance. The participant loans outstanding at December 31, 1999 and 1998 were $638,014 and $537,064. Such loans bear interest at the "prime rate" plus 1% at interest rates ranging from 7.00% to 9.75% for the years ended December 31, 1999 and 1998. Principal and interest are repaid ratably through payroll deductions. Forfeitures The Plan allows for forfeitures of terminated participants' non-vested amounts to be transferred to the CIGNA Charter Guaranteed Long-Term Fund account at the time of the terminated participant's distribution or after a five year break-in-service period. Prior to the five year break-in-service limit, the forfeitures are held in the respective funds in a time restricted account on behalf of the Plan Sponsor. The Plan Sponsor may use these funds to offset administrative expenses. 12 13 Computer Network Technology Corporation 401(k) Salary Savings Plan NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1999 and 1998 NOTE C - INVESTMENTS The following fair values represent 5 percent or more of the Plan's net assets.
