Note 4—Cash, Cash Equivalents, Restricted Cash and Restricted Cash Equivalents

The Company’s cash and cash equivalents include cash and certain highly liquid investments with original maturities of 90 days or less from the date of purchase. Cash equivalents are primarily recorded at cost, which approximates fair value due to their generally short maturities.
