Please answer the given financial question based on the context.
Context: 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|
