Cash Overdrafts And Cash Equivalents [Abstract]
Cash Overdrafts And Cash Equivalents	9. Cash Overdrafts and Cash Equivalents Included in the accompanying Consolidated Balance Sheets are $3.9 million, $1.8 million, and $3.2 million of capitalized property and equipment which were not paid for as of December 31, 2020, December 31, 2019 and December 31, 2018, respectively. These amounts have been excluded from capital expenditures in the accompanying Consolidated Statements of Cash Flow. There are no material non-cash amounts included in interest expense for any period presented. There are no cash overdrafts included in accounts payable as of December 31, 2020. Included in accounts payable are cash overdrafts of $9.8 million as of December 31, 2019. From time to time throughout the year, we invest excess cash in money market funds directly with major commercial banks. We closely monitor the creditworthiness of the institutions with which we invest our overnight funds. The amount invested was less than $100,000 for each balance sheet date presented.

The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.
