(2) interest on indebtedness incurred or continued to purchase or carry obligations or securities the interest on which is exempt from tax under this chapter; and

(3) ordinary and necessary expenses paid or incurred during the taxable year for: (i) the production or collection of income which is subject to tax under this chapter but exempt from federal income tax, or (ii) the management, conservation or maintenance of property held for the production of such income, and the amortizable bond premium for the taxable year on any bond the interest on which is subject to tax under this chapter but exempt from federal income tax, to the extent that such expenses and premiums are not deductible in determining federal adjusted gross income and are not subtracted from federal adjusted gross income pursuant to paragraph ten of subdivision (c) of section 11-1712.
