Calculation of AT15 in TPM60

Can someone please let me know how the the forex swap points are calculated from AT15 table in TPM60?

Example: I have a FX contract between X and Y currency with a value date of Dec 26th. I run the TPM60 with a key date valuation of Nov 30th. Suppose we use a work day calendar.

I have the following most recent AT15 rates available for these two currencies:

From currency   To Currency Term   Rate

X                         Y                  1        A

X                          Y                 7        B

X                         Y               15         C

X                         Y               31         D

Would the rate from all these terms would be taken during calculation?

Thank you!
