5. Restricted cash
Our restricted cash balance was $329.2 million and $419.4 million as of December 31, 2016 and 2015, respectively. It is primarily related to our ECA financings, our Ex-Im financings, our AerFunding revolving credit facility and other debt. See Note 16—Debt.
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.
