Summary
of Accounting
Policies
|
·
|
The
fair value of common stock shares are based upon the closing market
price
on the valuation date.
|
·
|
Shares
of mutual funds are valued at the net asset value of the shares
held by
the Plan at year-end.
|
·
|
The
fair value of the fully benefit-responsive investment contracts
held by
the Fidelity Managed Income Portfolio are calculated using a discounted
cash flow model which considers recent fee bids as determined by
recognized dealers, discount rate and the duration of the underlying
portfolio securities.
|
·
|
Participant
loans are valued at their outstanding balance, which approximates
fair
value.
