…..BALANCE SHEET…..The Company’s total consolidated assets were $1.4 billion at June 30, 2021, which increased by $80.9 million, or 6.3%, from the December 31, 2020 asset level. This change was related, primarily, to increased levels of cash and cash equivalents, investment securities, and loans. Specifically, cash and cash equivalents increased $28.7 million, or 91.2%, as the Company experienced a significant influx of deposits resulting from the government stimulus programs and financial assistance provided to municipalities and school districts. Our liquidity position was also positively impacted by the Somerset County branch acquisition completed in May 2021, which provided approximately $42 million of additional deposits. Total investment securities increased $31.0 million, or 16.5%, as the steepening of the U.S. Treasury yield curve in the latter part of the first quarter improved the yield for federal agency mortgage-backed securities and federal agency bonds, making these types of securities more attractive for purchase. The Company also continued to purchase corporate securities, particularly subordinated debt issued by other financial institutions, along with taxable municipal securities. In addition, loans, net of unearned fees, and loans held for sale increased by $14.5 million, or 1.5%, as a result of the Company’s participation in the PPP and higher levels of commercial real estate and residential mortgage loan production. Finally, other assets increased $8.2 million, or 80.6%, as a result of a reclassification of the accrued pension liability, which had a positive balance of $11.4 million as of June 30, 2021, from other liabilities to other assets. The balance of the accrued pension liability became a positive value as a result of the $4.0 million contribution made earlier in 2021 and the revaluation of the obligation due to the settlement charge during the second quarter of 2021.
Total deposits increased by $113.8 million, or 10.8%, in the first six months of 2021. As previously mentioned, this robust growth is the result of the government stimulus programs and the Somerset County branch acquisition. As of June 30, 2021, the 25 largest depositors represented 21.2% of total deposits, which remained relatively unchanged from December 31, 2020 when it was 21.1%. Total borrowings have decreased by $41.7 million, or 36.5%, since year-end 2020. The decrease was driven, primarily, by a lower level of both short-term borrowings and FHLB term advances. Specifically, at June 30, 2021, the Company had no short-term borrowings outstanding as compared to $24.7 million at December 31, 2020. In addition, FHLB term advances decreased by $16.8 million, or 25.9%, and totaled $48.1 million at June 30, 2021. The current strong liquidity position has allowed the Company to paydown FHLB advances. However, the Company continues to utilize the FHLB term advances to help manage interest rate risk.
The Company’s total shareholders’ equity increased by $6.9 million, or 6.6%, over the first six months of 2021 due to the retention of earnings more than offsetting our common stock dividend payments to shareholders. Additionally, the recording of the settlement charge in connection with the defined benefit pension plan and the revaluation of the pension obligation had a positive impact on accumulated other comprehensive loss.
The Company continues to be considered well capitalized for regulatory purposes with a total capital ratio of 12.79%, and a common equity tier 1 capital ratio of 9.94% at June 30, 2021. See the discussion of the Basel III capital requirements under the Capital Resources section below. As of June 30, 2021, the Company’s book value per common share was $6.52 and its tangible book value per common share was $5.71 (non-GAAP). When compared to December 31, 2020, book value per common share improved by $0.40 per common share and tangible book value per common share improved by $0.29 per common share. The tangible common equity to tangible assets ratio was 7.24% (non-GAAP) at June 30, 2021 and declined by five basis points when compared to December 31, 2020.
The tangible common equity ratio and tangible book value per share are considered to be non-GAAP measures and are calculated by dividing tangible equity by tangible assets or shares outstanding. The Company believes that these non-GAAP financial measures provide information to investors that is useful in understanding its financial condition. This non-GAAP data should be considered in addition to results prepared in accordance with GAAP, and is not a substitute for, or superior to, GAAP results. Limitations associated with non-GAAP financial measures include the risks that persons might disagree as to the appropriateness of items included in these measures, and, because not all companies use the same calculation of tangible common equity and tangible assets, this presentation may not be comparable to other similarly titled measures calculated by other companies.
