applicable regulations and laws.
The investment strategy utilizes asset diversification as a principal determinant for establishing an appropriate risk profile while emphasizing total return realized from capital appreciation, dividends and interest income.
The target allocations for plan assets are generally 45 to 80 percent equity securities, 5 to 40 percent debt securities, and 5 to 30 percent money-market funds/cash equivalents and other investments, although holdings could be more or less than these general guidelines based on market conditions at the time and actions taken or recommended by the investment managers providing advice to the Company.
Equity securities include investments in domestic and international equities, including through mutual funds.
Debt securities include investments in corporate bonds of companies from diversified industries, mortgage-backed securities guaranteed by government agencies, U. S.  Treasury securities, and mutual funds that invest in debt securities.
Additionally, the Company’s defined benefit pension plan held $209,878,000 (12.9% of total assets) of real estate, private investments, hedge funds and other investments at December 31, 2015.
Returns on invested assets are periodically compared with target market indices for each asset type to aid management in evaluating such returns.
Furthermore, management regularly reviews the investment policy and may, if deemed appropriate, make changes to the target allocations noted above.
The fair values of the Company’s pension plan assets at December 31, 2015, by asset category, were as follows:
## Table 1 ##
The Company does not believe that the estimated information presented herein is representative of the earnings power or value of the Company.
The preceding analysis, which is inherently limited in depicting fair value, also does not consider any value associated with existing customer relationships nor the ability of the Company to create value through loan origination, deposit gathering or fee generating activities.
Many of the estimates presented herein are based upon the use of highly subjective information and assumptions and, accordingly, the results may not be precise.
Management believes that fair value estimates may not be comparable between financial institutions due to the wide range of permitted valuation techniques and numerous estimates which must be made.
Furthermore, because the disclosed fair value amounts were estimated as of the balance sheet date, the amounts actually realized or paid upon maturity or settlement of the various financial instruments could be significantly different.21.
Commitments and contingencies In the normal course of business, various commitments and contingent liabilities are outstanding.
The following table presents the Company’s significant commitments.
Certain of these commitments are not included in the Company’s consolidated balance sheet.
## Table 2 ##
Commitments to extend credit are agreements to lend to customers, generally having fixed expiration dates or other termination clauses that may require payment of a fee.
Standby and commercial letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party.
Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party, whereas commercial letters of credit are issued to facilitate commerce and typically result in the commitment being funded when the underlying transaction is consummated between the customer and a third party.
The credit risk associated with commitments to extend credit and standby and commercial letters of credit is essentially the same as that involved with extending loans to customers and is subject to normal credit policies.
Collateral may be obtained based on management’s assessment of the customer’s creditworthiness.
Financial guarantees and indemnification contracts are oftentimes similar to standby letters of credit and include mandatory purchase agreements issued to ensure that customer obligations are fulfilled, recourse obligations associated with sold loans, and other guarantees of customer performance or compliance with designated rules and regulations.
Included in financial guarantees and indemnification contracts are loan principal amounts sold with recourse in conjunction with the Company’s involvement in the Fannie Mae DUS program.
The Company’s maximum credit risk for recourse associated with loans sold under this program totaled approximately $2.5 billion and $2.4 billion at December 31, 2015 and 2014, respectively.
Since many loan commitments, standby letters of credit, and guarantees and indemnification contracts expire without being funded in whole or in part, the contract amounts are not necessarily indicative of future cash flows.
