Prior to 2018, the Company's investments in LIHTC partnerships were accounted for using the cost method. In 2018, the Company voluntarily changed its accounting policy for LIHTC partnerships from the cost method to the proportional amortization method using the practical expedient available under ASC 323, "Investments - Equity Method and Joint Ventures", which permits an investor to amortize the initial cost of the investment in proportion to only the tax credits allocated to the investor. The Company believes the proportional amortization method is preferable because it better reflects the economics of an investment that is made for the primary purpose of receiving tax credits and other tax benefits. In addition to a change in the timing of the recognition of amortization expense on LIHTC investments, amortization expense on LIHTC investments is now reflected in the income tax expense line, which provides users a better understanding of the nature of the returns of such investments, instead of in other operating expenses on the consolidated statements of income.

The following table presents amortization and tax credits recognized associated with our investments in LIHTC partnerships for the three months ended March 31, 2019 and March 31, 2018:



(dollars in thousands)	Three Months Ended March 31, 2019		Three Months Ended March 31, 2018
Proportional amortization method:
Amortization expense recognized in income tax expense	$	258	$	114
Tax credits recognized in income tax expense	277		152
