NOTE 12 DERIVATIVE INSTRUMENTS AND FAIR VALUE MEASUREMENTS The Company is exposed to certain market risks such as changes in interest rates, foreign currency exchange rates, and commodity prices, which exist as a part of its ongoing business operations.
Management uses derivative financial and commodity instruments, including futures, options, and swaps, where appropriate, to manage these risks.
Instruments used as hedges must be effective at reducing the risk associated with the exposure being hedged and must be designated as a hedge at the inception of the contract.
The Company designates derivatives as cash flow hedges, fair value hedges, net investment hedges, and uses other contracts to reduce volatility in interest rates, foreign currency and commodities.
As a matter of policy, the Company does not engage in trading or speculative hedging transactions.
Total notional amounts of the Company’s derivative instruments as of December 29, 2012 and December 31, 2011 were as follows:
## Table 0 ##
Following is a description of each category in the fair value hierarchy and the financial assets and liabilities of the Company that were included in each category at December 29, 2012 and December 31, 2011, measured on a recurring basis.
Level 1 — Financial assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market.
For the Company, level 1 financial assets and liabilities consist primarily of commodity derivative contracts.
Level 2 — Financial assets and liabilities whose values are based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability.
For the Company, level 2 financial assets and liabilities consist of interest rate swaps and over-the-counter commodity and currency contracts.
The Company’s calculation of the fair value of interest rate swaps is derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve.
Over-the-counter commodity derivatives are valued using an income approach based on the commodity index prices less the contract rate multiplied by the notional amount.
Foreign currency contracts are valued using an income approach based on forward rates less the contract rate multiplied by the notional amount.
The Company’s calculation of the fair value of level 2 financial assets and liabilities takes into consideration the risk of nonperformance, including counterparty credit risk.
Level 3 — Financial assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement.
These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability.
The Company did not have any level 3 financial assets or liabilities as of December 29, 2012 or December 31, 2011.
Concentrations of Credit Risk Credit risk is the possibility of loss from the failure of a borrower, guarantor, or another obligor to fully perform under the terms of a credit-related contract.
Credit risks (whether on- or off-balance sheet) may occur when individual borrowers, groups of borrowers, or counterparties have similar economic characteristics, including industries, geographies, collateral types, sponsors, etc.
, and are similarly affected by changes in economic or other conditions.
Credit risk also includes the loss that would be recognized subsequent to the reporting date if counterparties failed to perform as contracted.
See Note 7 for a discussion of counterparty risk associated with the Company’s derivative transactions.
We perform an ongoing analysis of our loan portfolio to evaluate whether there is any significant exposure to any concentrations of credit risk.
Based on this analysis, we believe that the loan portfolio is generally well diversified; however, there are certain significant concentrations in CRE and oil and gas-related lending.
Further, we cannot guarantee that we have fully understood or mitigated all risk concentrations or correlated risks.
We have adopted and adhere to concentration limits on various types of CRE lending, particularly construction and land development lending, leveraged and enterprise value lending, municipal lending, and oil and gas-related lending.
All of these limits are continually monitored and revised as necessary.
Purchased Loans Background and Accounting We purchase loans in the ordinary course of business and account for them and the related interest income based on their performing status at the time of acquisition.
PCI loans have evidence of credit deterioration at the time of acquisition and it is probable that not all contractual payments will be collected.
Interest income for PCI loans is accounted for on an expected cash flow basis.
Certain other loans acquired by the Company that are not creditimpaired include loans with revolving privileges and are excluded from the PCI tabular disclosures following.
Interest income for these loans is accounted for on a contractual cash flow basis.
Upon acquisition, in accordance with applicable accounting guidance, the acquired loans were recorded at their fair value without a corresponding ALLL.
Certain acquired loans with similar characteristics such as risk exposure, type, size, etc.
, are grouped and accounted for in loan pools.
Outstanding Balances and Accretable Yield The outstanding balances of all required payments and the related carrying amounts for PCI loans are as follows:
## Table 1 ##
At the time of acquisition of PCI loans, we determine the loan’s contractually required payments in excess of all cash flows expected to be collected as an amount that should not be accreted (nonaccretable difference).
With respect to the cash flows expected to be collected, the portion representing the excess of the loan’s expected cash flows over our initial investment (accretable yield) is accreted into interest income on a level yield basis over the remaining expected life of the loan or pool of loans.
The effects of estimated prepayments are considered in estimating the expected cash flows.
Certain PCI loans are not accounted for as previously described because the estimation of cash flows to be collected involves a high degree of uncertainty.
Under these circumstances, the accounting guidance provides that interest income is recognized on a cash basis similar to the cost recovery methodology for nonaccrual loans.

1 There is no Tier 1 leverage ratio component in the definition of a well-capitalized bank holding company.
Zions is also subject to “capital conservation buffer” regulatory requirements.
When fully phased-in on January 1, 2019, the Basel III Capital Rules will require the Company and its subsidiary bank to maintain a 2.5% capital conservation buffer, designed to absorb losses during periods of economic stress, composed entirely of Common Equity Tier 1 (“CET1”), on top of the minimum risk-weighted asset ratios, effectively resulting in minimum ratios of (i) CET1 to risk-weighted assets of at least 7%, (ii) Tier 1 capital to risk-weighted assets of at least 8.5%, and (iii) Total capital to risk-weighted assets of at least 10.5%.
Banking institutions with a ratio of CET1 to risk-weighted assets above the minimum but below the capital conservation buffer will face constraints on dividends, equity repurchases, and compensation.
The implementation of the buffer will be phased-in beginning January 1, 2016 at the 0.625% level and increase by 0.625% on each subsequent January 1, until it reaches 2.5% on January 1, 2019.
Zions’ triggers and limits under actual conditions and baseline projections are more restrictive than the capital conservation buffer requirements.19.
RETIREMENT PLANS Defined Benefit Plans Pension – This qualified noncontributory defined benefit plan is frozen to new participation.
No service-related benefits have been since July 1, 2013.
All participants in the Plan are currently 100% vested in their benefits.
Plan assets consist principally of corporate equity securities, mutual fund investments, real estate, and fixed income investments.
Plan benefits are paid as a lump-sum cash value or an annuity at retirement age.
Contributions to the plan are based on actuarial recommendation and pension regulations.
Although there was no minimum regulatory contribution required in 2016, we elected to contribute $4 million to the pension plan.
Currently, it is expected that no minimum regulatory contributions will be required in 2017.
Supplemental Retirement – These unfunded nonqualified plans are for certain current and former employees.
Each year, Company contributions to these plans are made in amounts sufficient to meet benefit payments to plan participants.
Postretirement Medical/Life – This unfunded health care and life insurance plan provides postretirement medical benefits to certain full-time employees who meet minimum age and service requirements.
The plan also provides specified life insurance benefits to certain employees.
The plan is contributory with retiree contributions adjusted annually, and contains other cost-sharing features such as deductibles and coinsurance.
Plan coverage is provided by self-funding or health maintenance organization options.
Our contribution towards the retiree medical premium has been permanently frozen at an amount that does not increase in any future year.
Retirees pay the difference between the full premium rates and our capped contribution.
