Basis of Accounting

The accompanying financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America.

Investments are reported at fair value. Common stock and mutual funds are valued at the closing price reported on the active market on which the individual securities are traded. Dividend income is recorded on the ex-dividend date. Purchases and sales of securities are recognized on the trade date basis. Net appreciation/depreciation includes the Plan’s gains and losses on investments bought and sold as well as held during the year.
