ARC-CO and PLC: Using Farmdoc Tools to Aid Your Decision

    ©Debra L Ferguson Stock Photography

    Two tools are available on the farmdoc website for evaluating Commodity title choices faced by farmers.  The first is the 2018 Farm Bill What-If Tool, a Microsoft Excel spreadsheet that calculates payments under differing price and yield scenarios. The second is the Gardner ARC/PLC Calculator, which provides probabilities and estimates of likely payments.

    The tools are demonstrated for corn in Macon County.  Results suggest that PLC will have a higher chance of payments than ARC-CO, likely causing it to be the preferred alternative by many farmers.


    By March 15th, farmers can change their Commodity title choices for the 2021 marketing year. The choices will be made between:

    1. Price Loss Coverage (PLC) — a program that makes payments when the market year average (MYA) price is below the effective reference price.
    2. Agriculture Risk Coverage at the County Level (ARC-CO) — a program that makes payments when county revenue is below a county guarantee.
    3. Agriculture Risk Coverage at the Individual Level (ARC-IC) — a program under which an Farm Service Agency (FSA) farm is enrolled in a farm-level program (all FSA farms are aggregated together in a state if more than one FSA farm is enrolled).

    This article focuses on the PLC and ARC-CO decisions. Aside from special situations, most farmers are not likely to choose ARC-IC because it pays on fewer base acres than the other two programs. The farm program selection can vary across program crops on an FSA farm.

    For example, PLC could be chosen for corn, and ARC-CO can be chosen for soybeans on the same FSA farm. Moreover, decisions can vary across FSA farms. For example, corn can be enrolled in PLC on one FSA farm and in ARC-CO on another FSA farm.

    Tools are illustrated for corn in Macon County, Illinois, with a PLC yield of 185 bushels per acre. The PLC yield is FSA farm-specific and has been set based on previous yield updating decisions.  Farmers can consult FSA offices for a farm’s PLC yield.

    Both tools are available from the Tools menu on both the farmdoc daily and farmdoc websites (see Figure 1).

    2018 Farm Bill What-If Tools

    The 2018 Farm Bill What-If Tool can evaluate ARC-CO, PLC, and ARC-IC. The specific utility illustrated below is the “ARC-CO PLC Comparison,” which compares ARC-CO and PLC payments under different price and yield scenarios.

    Figure 2 shows the input for the Macon County case farm. Corn is selected, and the practice is “all” because Macon County does not have an irrigation practice option. Some counties in Illinois have both irrigated and non-irrigated practices.  The PLC yield is 185 bushels per acre, and the year is “2021”. The tool has the ability to evaluate payments for:

    1. 2019 (actual payments made in 2019),
    2. 2020 (payments that may occur in the fall of 2021), and
    3. 2021 (the upcoming year for which decisions will be made, payments that may occur in the fall of 2022).

    For 2021, a default county yield of 227 bushels per acre is used. This projected county yield is the same yield as the ARC-CO benchmark yield. The MYA price for 2021 is projected at $4.00 per bushel, a projection made based on current levels of futures prices. The 2021 projected yield and price does not result in a PLC or ARC-CO payment.

    The spreadsheet will show a table of different PLC and ARC-CO payments at different yields and prices. Figure 3 shows PLC payments. Note that the program selection entry in blue letters and yellow background can be changed from “PLC” to “ARC-CO” or “PLC minus ARC-CO.” For PLC, payments occur at prices below the effective reference price of $3.70 per bushel.

    At a $3.50 price, the PLC payment is $31 per corn per acre. The $31 equals .85 x ($3.70 reference price – $3.50 MYA price) x 185 PLC yield. The PLC payment is dependent on the farm PLC yield but will be the same at a $3.50 price regardless of county yield.

    The PLC payment increases as price decreases further from the $3.70 trigger point: $71 per base acre at a $3.25 MYA Price, $110 at a $3.00 MYA price, and $149 at a $2.75 MYA price.

    Figure 4 shows ARC-CO payments (note that the program selection is “ARC-CO”). For Macon County, the benchmark yield is 226.86 bushels per acre, the Olympic average of county yield from 2015 to 2019. The ARC-CO benchmark price is $3.70, the Olympic average of MYA prices from 2015 to 2019, with a minimum of the $3.70 reference price used in each year.

    This benchmark yield and benchmark price results in a guarantee of $721.87 per acre (.86 coverage level x 226.86 benchmark yield x $3.70 benchmark price). ARC-CO will make payments when county revenue is below the $721.87 guarantee. An $18 per base acre payment will occur at a $3.75 price and a 187 bushel per acre county yield ($18 per acre = .85 x ($721.87 – 187 bushel per acre yield x $3.85 price).

    The payment is capped at 10% of the guarantee, or $71 per acre. At a $4.00 price, the maximum ARC-CO payment of $71 per base acre would occur at a county yield of 127 bushels per acre or less. ARC-CO payments will not increase with lower yields at this price level because the ARC-CO payment has reached its maximum.

    ARC-CO will make payments under a low yield, a low price, or a combination of low yield and low price. At a $4.00 price, ARC-CO would begin to make payments at yields below 181 bushels per acre. While possible, yields below 181 bushels per acre have a low likelihood of occurring.

    The What-If Tool also will show “PLC minus ARC-CO” (see Figure 5). In Figure 5, there is a -$46 per base acre entry for a $4.00 MYA price and a 167 bushel per acre yield. The -$46 equals $0 in PLC payments minus $46 in ARC-CO payments.

    A positive number indicates that PLC makes higher payments than ARC-CO. Negative values indicate that ARC-CO is making higher payments than PLC. Values of $0 usually mean that neither program is making a payment.

    At prices between $3.25 and $3.70 and moderate to high yields, PLC will make higher payments than ARC-CO (see Figure 5). At prices below $3.25, PLC will make higher payments than ARC-CO. At low yields and prices above $3.25, ARC-CO will make higher payments than PLC.

    Gardner ARC/PLC Calculator

    The online ARC/PLC Calculator is shown in Figure 6. Inputs are corn for Macon County, Illinois, with a PLC yield of 185 bushels per acre. The tool gives expected payments for 2019 through 2023. The year 2019 has passed, and Commodity Title payments have been made. In 2019, Macon County did not receive an ARC-CO payment for corn. There was a PLC payment of $21.90 for a PLC yield of 185 bushels per acre.

    For the 2021 decision, the focus should be given to the 2021 results (in the red box). This tool reports results from a simulation of possible 2021 yields and prices calibrated based on historical results. The expected MYA price for 2021 is $4.00, an average of many different price scenarios that result in an average of $4.00 over all scenarios.

    The 2021 expected yield is 217.2 bushels per acre, the average over many scenarios. The 217.2 yield is based on a history of yields and assumes a trend increase in yields.

    For 2021, the likelihood of a PLC payment is 33%. This means that 33% of the time, the model estimates that the 2021 MYA price will be below the $3.70 effective reference price. This 33% probability is based on historical changes in prices.

    The expected payment for PLC in 2021 is $19.13 per base acre. This includes the 77% of the time that PLC does not make a payment.

    For 2021, the likelihood of an ARC-CO payment is 12%. This means that the ARC-CO combination that makes payments in the 2018 What If Tool (see Figure 6) are estimated to occur only 12% of the time. Much of the reason for this low likelihood is because of the low yields needed to trigger ARC-CO payments. History would suggest that those low yields happen rarely.

    The expected payment from ARC-CO is $5.08 per base acre. This $5.08 includes the 12% of times that ARC-CO makes payments and the 88% of the time it does not make payments.

    Making the Decision

    The ARC/PLC calculator indicates the following for Macon County, Illinois in 2021;

    • Both PLC and ARC-CO are unlikely to make payments.
    • PLC has a higher likelihood of payments for corn than ARC-CO: 33% for PLC versus 12% for ARC-CO.
    • PLC has a higher expected payment for corn than ARC-CO: $19.02 per base acre for PLC versus $5.08 for ARC-CO.

    The 2018 Farm Bill What-If Tool indicates that PLC will pay more than ARC-CO at prices below $3.70 and moderate to high yields. ARC-CO will pay more than PLC at prices above $3.25 and low yields. Those low yields would generally be in drought situations, often resulting in higher prices.

    Based on the above results, we would suggest that farmers lean towards taking PLC. This choice also allows for the Supplemental Coverage Option (SCO) to be chosen as a crop insurance policy. The most likely case in which PLC will not result in a higher payment than ARC-CO is in a drought year. In a drought year, yields could be 100 bushels lower than the 217.2 trend or in the 127 bushels per acre range.

    However, if yields are that low, prices would likely rise and reduce the likelihood and size of payments from ARC-CO. For example, at a 127 bushel yield in Macon County, prices at $5.68 or above would not generate an ARC-CO payment.
