Investments in Affordable Housing Partnerships Policy	The Company has invested in certain limited partnerships that were formed to develop and operate apartments and single-family houses designed as high-quality affordable housing for lower income tenants throughout Missouri and contiguous states. At December 31, 2017, the Company had 16 investments, with a net carrying value of $18.2 million. At December 31, 2016, the Company had 13 investments, with a net carrying value of $21.8 million. Due to the Company’s inability to exercise any significant influence over any of the investments in Affordable Housing Partnerships, they all are accounted for using the proportional amortization method. Each of the partnerships must meet the regulatory requirements for affordable housing for a minimum 15-year compliance period to fully utilize the tax credits. If the partnerships cease to qualify during the compliance period, the credits may be denied for any period in which the projects are not in compliance and a portion of the credits previously taken may be subject to recapture with interest. The remaining federal affordable housing tax credits to be utilized through 2023 were $40.0 million as of December 31, 2017, assuming no tax credit recapture events occur and all projects currently under construction are completed as planned. Amortization of the investments in partnerships is expected to be approximately $34.9 million, assuming all projects currently under construction are completed and funded as planned. The Company’s usage of federal affordable housing tax credits approximated $6.6 million, $6.2 million and $6.3 million during 2017, 2016 and 2015, respectively. Investment amortization amounted to $5.2 million, $4.4 million and $4.9 million for the years ended December 31, 2017, 2016 and 2015, respectively.
