Some of the financial measures included in this presentation are not measures of financial performance recognized by GAAP. These non-GAAP financial measures include “tangible common equity to tangible assets,” “tangible book value per share,” and “return on average tangible common equity.” Our management uses these non-GAAP financial measures in its analysis of our performance and believes these are helpful to investors as an additional tool for further understanding our performance.

Some of the financial measures included in this presentation and in forms 10-Q & 10-K filed with the SEC differ from those reported on the FRB Y-9(c) report. These financial measures include “core deposits to total deposits.” Our management uses this financial measure in its analysis of our performance. The Bank measures core deposits by reviewing all relationships over $250,000 on a quarterly basis. After discussions with our regulators on the proper way to measure core deposits, we now track all deposit relationships over $250,000 on a quarterly basis and consider a relationship to be core if there are any three or more of the following: (i) relationships with us (as a director or shareholder); (ii) deposits within our market area; (iii) additional non-deposit services with us; (iv) electronic banking services with us; (v) active demand deposit account with us; (vi) deposits at market interest rates; and (vii) longevity of the relationship with us. We consider all deposit relationships under $250,000 as a core relationship except for time deposits originated through an internet service. This differs from the traditional definition of core deposits which is demand and savings deposits plus time deposits less than $250,000. As many of our customers have more than $250,000 on deposit with us, we believe that using this method reflects a more accurate assessment of our deposit base. The following table reconciles the adjusted core deposit to total deposits: Regulatory Reporting to Financial Statements: Adjusted Core Deposits All demand and savings deposits of any amount plus time deposits less than $250,000 Time deposits to core customers over $250,000 as defined in the lead-in to the table above Comprised of internet and outside deposit originator time deposits less than $250,000 which are not considered to be core deposits Comprised of demand and savings deposits in relationships over $250,000 which are considered non-core deposits because they do not satisfy the definition of core deposits set forth in the lead-in to the table above  (Dollars in thousands)   As of the period ended       2013   2014   2015   2016   2017   2018 2019 2Q20 Core Deposits¹ $422,252 $507,376 $567,980 $781,940 $990,824 $1,670,572 $1,651,678 $1,874,532 Adjustments to Core Deposits Time Deposits > $250,000 Considered as Core Deposits² 118,756 115,572 174,038 325,453 180,751 468,773 446,968 439,183 Less: Brokered Deposits Considered Non-Core - - - - - (113,832) (67,089) (2,378) Less: Internet and Other Deposit Originator Deposits < $250,000 Considered Non-Core³ - (44,562) (21,418) (30,971) (29,467) (18,286) (26,025) (86,356) Less: Other Deposits Not Considered Core⁴ - - (70,759) (171,800) (136,943) (52,002) (60,719) (59,772) Adjusted Core Deposits $541,008 $578,386 $649,841 $904,622 $1,005,165 $1,955,225 $1,944,813 $2,165,209 Total Deposits 574,079 767,365 853,417 1,152,763 1,337,281 2,144,041 2,249,061 2,436,520 Adjusted Core Deposits to Total Deposits Ratio 94.24% 75.37% 76.15% 78.47% 75.16% 91.19% 86.47% 88.86% Regulatory Reporting to Financial Statements: Adjusted Core Deposits Some of the financial measures included in this presentation and in forms 10-Q & 10-K filed with the SEC differ from those reported on the FRB Y-9(c) report.
