This change in loan category classification was made to better align the Company’s financial reporting classifications with regulatory reporting classifications, and to properly classify these loans for regulatory risk-based capital ratio calculations. As a result of these reclassifications, at September 30, 2017, loans with balances of $60,957,000, and $5,620,000, that would have been classified as commercial real estate mortgage loans prior to this change, were classified as residential real estate mortgage loans, and consumer home equity loans, respectively; and the Company’s, and the Bank’s, Total risk based capital ratios, Tier 1 capital ratios, and Tier 1 common equity ratios were all recalculated to be <font style="WHITE-SPACE: nowrap">0.10%-0.20%</font> higher than they would have been prior to this change. Certain amounts reported in previous consolidated financial statements have been reclassified and recalculated to conform to the presentation in this report.
