(iii)One-half the number of days remaining in the period defined by paragraph (c)(1) of this section after that period is reduced in accordance with paragraphs (d)(1)
(i)and
(ii)of this section; half days will be ignored for purposes of subtraction;
(2)By adding the number of days determined in paragraph (d)(1) of this section to the original term of the patent as shortened by any terminal disclaimer;
(3)By adding 14 years to the date of approval of the application under section 512 of the Federal Food, Drug, and Cosmetic Act;
(4)By comparing the dates for the ends of the periods obtained pursuant to paragraphs (d)(2) and (d)(3) of this section with each other and selecting the earlier date;
