Great!I think with this change and the footnote change for the Tables 4-4 to 4-6,

the RIA should be ready to go. Once it’s done, can you send me a redline and clean version of the RIA?

Thanks,

Cortney

Okay, thanks. I will put these sentences in a paragraph just before Table 1-1 as the following:

It should be noted that there is a difference between the annualized social costs estimated at 3% and 7%. We approximate the annualized social costs with the compliance costs of the rule for the RIA, as we mention later in Section 5. The annualized compliance costs of the rule are estimated to be $244 million (2009 dollars) using a 3% interest rate. Thus, the annualized social costs for a 3% rate are also $244 million using our approximation, and this estimate is very close to the annualized social cost estimate at a 7% rate.
Please let me know if you have any questions or comments.

No, the text around the summary table in the RIA (the very first table thathas the costs and benefits for the rule).

Cortney, by table, are you referring to the impacts table in ROCIS? If so, I will do this.

Can you clarify this in the text around the table by adding sentences based on what you wrote below, e.g. “There is a difference between the social costs estimated at 3% and 7%. We approximate the annualized social costs with the compliance costs of the rule for this RIA, as we mention in Section 5. The annualized compliance costs of the rule are estimated to be $244 million using a 3% interest rate. Thus, the annualized social costs for a 3% rate are $244 million using our approximation, and this estimate is very close to the estimate at a 7% rate.”

Cortney,There is a difference between the social costs estimated at 3% and 7%.

We approximate the annualized social costs with the compliance costs of the rule for this RIA, as we mention in Section 5. The annualized compliance costs of the rule are estimated to be $244 million using a 3% interest rate, according to the ROCIS form. Thus, the annualized social costs for a 3% rate are $244 million using our approximation, though this estimate is actually quite close to the estimate at a 7% rate. Thanks.

The footnote (3) explains that the annual compliance costs are a proxy for the annual social costs, but it doesn't explain why there's no difference. Regards, Cortney
