the descriptions and fair value methodologies for the u.s .and international pension plan assets are as follows : cash and cash equivalents the carrying amounts of cash and cash equivalents approximate fair value due to the short-term maturity .equity securities equity securities are valued at the closing market price reported on a u.s .or international exchange where the security is actively traded and are therefore classified as level 1 assets .equity mutual and pooled funds shares of mutual funds are valued at the net asset value ( nav ) of the fund and are classified as level 1 assets .units of pooled funds are valued at the per unit nav determined by the fund manager based on the value of the underlying traded holdings and are classified as level 2 assets .corporate and government bonds corporate and government bonds are classified as level 2 assets , as they are either valued at quoted market prices from observable pricing sources at the reporting date or valued based upon comparable securities with similar yields and credit ratings .other pooled funds other pooled funds classified as level 2 assets are valued at the nav of the shares held at year end , which is based on the fair value of the underlying investments .securities and interests classified as level 3 are carried at the estimated fair value .the estimated fair value is based on the fair value of the underlying investment values , which includes estimated bids from brokers or other third-party vendor sources that utilize expected cash flow streams and other uncorroborated data including counterparty credit quality , default risk , discount rates , and the overall capital market liquidity .insurance contracts insurance contracts are classified as level 3 assets , as they are carried at contract value , which approximates the estimated fair value .the estimated fair value is based on the fair value of the underlying investment of the insurance company and discount rates that require inputs with limited observability .contributions and projected benefit payments pension contributions to funded plans and benefit payments for unfunded plans for fiscal year 2018 were $ 68.3 .contributions for funded plans resulted primarily from contractual and regulatory requirements .benefit payments to unfunded plans were due primarily to the timing of retirements .we anticipate contributing $ 45 to $ 65 to the defined benefit pension plans in fiscal year 2019 .these contributions are anticipated to be driven primarily by contractual and regulatory requirements for funded plans and benefit payments for unfunded plans , which are dependent upon timing of retirements .projected benefit payments , which reflect expected future service , are as follows: .
[['', 'u.s .', 'international'], ['2019', '$ 165.5', '$ 52.8'], ['2020', '152.4', '53.9'], ['2021', '157.0', '55.6'], ['2022', '163.7', '56.0'], ['2023', '167.9', '60.6'], ['2024-2028', '900.2', '336.8']]
these estimated benefit payments are based on assumptions about future events .actual benefit payments may vary significantly from these estimates. .
