[1] | FHLB Advances consist of an “Open RepoPlus” agreement with the FHLB of Pittsburgh. FHLB “Open RepoPlus” advances are short-term borrowings that bear interest based on the FHLB discount rate or Federal Funds rate, whichever is higher. The Company has a borrowing limit of $756,225,000, inclusive of any outstanding advances and letters of credit. FHLB advances are secured by a blanket security agreement that includes the Company’s FHLB stock, as well as certain investment and mortgage-backed securities held in safekeeping at the FHLB and certain residential and commercial mortgage loans. A portion of these advances, $25.0 million, are subject to interest rate swap arrangements. See Note 17 for additional information.
[2] | The federal funds lines consist of unsecured lines from two third party banks at market rates. The Company has a borrowing limit totaling $34,000,000, inclusive of any outstanding balances. No specific collateral is required to be pledged for these borrowings.
[3] | The Federal Reserve Bank Borrower in Custody (FRB BIC) Line consists of a borrower in custody in agreement opened in January 2010 with the Federal Reserve Bank of Philadelphia secured by municipal loans maintained in the Company’s possession. As of December 31, 2021 and 2020, the Company has a borrowing limit of $1,068,000 and $4,379,000, respectively, inclusive of any outstanding advances. The approximate carrying value of the municipal loan collateral was $1,683,000 and $12,932,000 as of December 31, 2021 and 2020, respectively.
[4] | In April 2021, the Company issued $10.0 million of fixed to floating rate subordinated notes that mature on April 16, 2031, unless redeemed earlier. The notes bear interest at 4% per annum through April 16, 2026 and subsequently pay interest at the 90-day average secured overnight financing rate, determined on the determination date of the applicable interest period, plus 323 basis points. The Company may redeem the notes, in whole or in part, on or after April 16, 2026, and at any time upon the occurrence of certain events, subject in each case to the approval of the Board of Governors of the Federal Reserve System (the “Federal Reserve”). Issuance costs associated with the notes totaled $131,000 and were capitalized and will be amortized over the life of the note on a straight-line basis, which approximates the effective yield method. As of December 31, 2021, the net unamortized issuance costs totaled $121,000.
[5] | In December 2003, the Company formed a special purpose entity (“Entity”) to issue $7,500,000 of floating rate obligated mandatory redeemable trust preferred securities as part of a pooled offering. The rate was determined quarterly and floated based on the 3 month LIBOR plus 2.80 percent. The Entity may redeem them, in whole or in part, at face value after December 17, 2008, and on a quarterly basis thereafter. The Company borrowed the proceeds of the issuance from the Entity in December 2003 in the form of a $7,500,000 note payable. Debt issue costs of $75,000 have been capitalized and fully amortized as of December 31, 2008. Under current accounting rules, the Company’s minority interest in the Entity was recorded at the initial investment amount and is included in the other assets section of the balance sheet. The Entity is not consolidated as part of the Company’s consolidated financial statements. The $7,500,000 note payable is subject to an interest rate swap arrangement. See Note 17 for additional information.
