Corn Rainfall Insurance Program

The Corn Rainfall Program is a weather-based program that insures against a lack of moisture for corn acres over the growing season. The program provides a risk management option to silage, grazing and grain corn producers.

2022 Program Enhancement

In the ‘monthly per cent of normal’ calculation, one millimetre of rainfall will be deducted for each day the temperature is above 31 degree Celsius. This adjustment will help recognize the impact of extreme heat on corn yields.

To Enrol

For each land location you wish to insure, you must select the following:

  • Weather Station
    Choose the weather station that best represents weather conditions for your land. Pay atention to the monthly normals.
    You are limited to selecting one weather station per insured parcel of land which is within 100 kilometres of your land.
  • Weighting Option
    You must select the weighting option for each land location insured. This allows you to weight the May to August precipitation to best suit the growing season for your region, corn variety and intended use when growing corn.
  • Precipitation Cap
    Select a precipitation cap of either 125 or 150 per cent of normal for each land location you insure. Any precipitation above this selected cap in any month will not be included in the claim calculation. The capping option helps in months when a significant rainfall event happens, but does not eliminate you from receiving indemnity when the rest of the year remains below normal. The 150 per cent cap will have lower premiums than the 125 per cent cap.

Premium

Premium rates are calculated for participating weather stations based on weather station historical precipitation data, the weighting option and the precipitation cap that you select. Experience discounts and surcharges do not apply to weather-based programs. Corn Heat Unit (CHU) and Corn Rainfall Program (CRP) acres are subject to USA premium as they are annual crop acres.

Coverage

Coverage is available at $150, $175, $250 or $350 per acre. At the time of enrolment, you must declare all acres selected for coverage. You may insure any number of acres; you do not need to insure all your corn acres. All acres on that contract must be insured at the same level of coverage.

Producers may select coverage through the CRP and the Corn Heat Unit Program; however, the same acres cannot be insured under the corn multi-peril yield-loss program. If selecting coverage under both CRP and CHU, your coverage level for each program will be $175/acre independently.

If you seed fewer acres than declared, your insured acres and premium will be adjusted accordingly. If you seed more acres, the declared acres will be used for premium calculations. Insured acres must be seeded to corn.

An establishment benefit of $95 per acre may be paid for corn crops which fail to adequately establish or suffer damage before June 20. A minimum of 10 acres or 10 per cent of the total acres seeded must have failed to establish to be eligible.

Monthly Precipitation Weighting Options

Under the Corn Rainfall Insurance Program, you must also select the weighting option for each land location insured. All precipitation options total to 100%.

Claims

A rainfall claim is triggered when the precipitation at your selected weather station is below 80 per cent of normal. 100 per cent of indemnity will be paid when precipitation falls below 32 per cent of normal. The indemnity payout is graduated with a higher percentage of indemnity paid with decreasing precipitation.

Indemnity paid is shown in the table below.

  • The rainfall indemnity calculation is based on your selected monthly precipitation weighting and your selected precipitation cap.
  • Quality control measures include verification of all weather station data by a third party (independent of SCIC) using procedures by an accredited meteorologist.
  • Precipitation includes all rainfall and snowfall amounts.
  • Only verified data is used in claim calculations.
  • Rainfall claims do not have to be filed; they are automatically calculated once weather station data is compiled (September). Verified monthly precipitation amounts will be available on our website and at your local customer service office.
  • Precipitation determined for the weather station is the only means of determining a rainfall claim.
  • Claims are not tied to individual yields or the amount of precipitation on individual parcels of land.
