	Note 1.   Basis of Presentation
	The consolidated financial statements of Center Bancorp, Inc. (the “Parent Corporation”) are prepared on the accrual basis and include the accounts of the Parent Corporation and its wholly-owned subsidiary, Union Center National Bank (the “Bank” and, collectively with the Parent Corporation and the Parent Corporation’s other direct and indirect subsidiaries, the “Corporation”). All significant intercompany accounts and transactions have been eliminated from the accompanying consolidated financial statements.
	In preparing the consolidated financial statements, management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of condition and that affect the results of operations for the periods presented. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to change in the near term relate to the determination of the allowance for loan losses, the other-than-temporary impairment evaluation of securities, the evaluation of the impairment of goodwill and the evaluation of deferred tax assets.
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”).

Earnings per Common Share	'
	Note 2.  Earnings per Common Share
	Basic earnings per common share (“EPS”) is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding. Diluted EPS includes any additional common shares as if all potentially dilutive common shares were issued (e.g., stock options). The Corporation’s weighted average common shares outstanding for diluted EPS include the effect of stock options and restricted stock awards outstanding using the Treasury Stock Method, which are not included in the calculation of basic EPS. Anti-dilutive stock option and restricted stock award shares outstanding were 29,248 and 30,610, respectively, for the three and nine months ended September 30, 2013, and anti-dilutive stock option shares outstanding were 20,838 and 75,208, respectively, for the three and nine months ended September 30, 2012.
	Earnings per common share have been computed based on the following:

Stock-Based Compensation [Abstract]	'
Stock-Based Compensation	'
	Note 3.  Stock-Based Compensation
	The Corporation maintains two stock-based compensation plans from which new grants could be issued. The Corporation’s stock-based compensation plans permit Parent Corporation common stock to be issued to key employees and directors of the Corporation and its subsidiaries. The options granted under the plans are intended to be either incentive stock options or non-qualified options. Under the 2009 Equity Incentive Plan, a total of 363,081 shares are available for grant and issuance as of September 30, 2013. Under the 2003 Non-Employee Director Stock Option Plan, a total of 380,644 shares remain available for grant and issuance under the plan as of September 30, 2013. Such shares may be treasury shares, newly issued shares or a combination thereof.
	Options have been granted to purchase common stock principally at the fair market value of the stock at the date of grant. Options are exercisable over a three year vesting period starting one year after the date of grant and generally expire ten years from the date of grant.
	Stock-based compensation expense for share-based payment awards is based on the grant date fair value estimated on the date of grant. The Corporation recognizes compensation costs for those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of three years. The Corporation estimates the forfeiture rate based on its historical experience during the preceding seven fiscal years.
	For the nine months ended September 30, 2013, the Corporation’s income before income taxes and net income were reduced by $54,000 and $32,000, respectively, as a result of the compensation expense related to stock options and restricted stock awards. For the nine months ended September 30, 2012, the Corporation’s income before income taxes and net income were reduced by $27,000 and $16,000, respectively, as a result of the compensation expense related to stock options.
	Under the principal stock-based compensation plans, the Corporation may also grant stock awards to certain employees. Stock awards are independent of option grants and are generally subject to forfeiture if employment terminates prior to the release of any applicable restrictions. Unless fully vested at the time of grant, such awards generally vest within 30 days to five years from the date of grant. During that period, ownership of the shares cannot be transferred. Restricted stock and stock awards that are fully vested at the time of grant have the same cash dividend and voting rights as other common stock and are considered to be currently issued and outstanding. The Corporation expenses the cost of stock awards, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which any restrictions lapse.
	There were 18,829 restricted stock awards outstanding at September 30, 2013 and none at September 30, 2012. These awards were issued with an award price equal to the market price of the Corporation’s common stock on the award date and with a five year vesting period. Forfeiture provisions exist for personnel that separate employment before vesting period expires. During the nine months of 2013, none of the shares of restricted stock were vested.
	There were 41,639 and 27,784 shares of common stock underlying options that were granted during the nine months ended September 30, 2013 and 2012, respectively. The fair value of share-based payment awards was estimated using the Black-Scholes option pricing model with the following assumptions and weighted average fair values at the time the grants were awarded:
		Nine Months Ended
		September 30,
		2013				2012
	Weighted average fair value of grants	$	3.34			$	2.03
	Risk-free interest rate		1.97	%			2.03	%
	Dividend yield		1.32	%			1.24	%
	Expected volatility		25.84	%			22.04	%
	Expected life in months		74				68
	Activity under the stock-based compensation plans as of September 30, 2013 and changes during the nine months ended September 30, 2013 were as follows:
							Weighted-
				Weighted-			Average
				Average			Remaining		Aggregate
				Exercise			Contractual		Intrinsic
		Shares		Price			Term (Years)		Value
	Outstanding at December 31, 2012	183,574		$	9.92
	Granted – options	41,639			12.95
	Exercised	-2,268			9.14
	Canceled/expired	-25,883			10.88
	Forfeited	-8,682			10.58
	Outstanding at September 30, 2013	188,380			10.55		6.25		$	705,001
	Exercisable at September 30, 2013	119,827		$	10.06		4.74		$	510,991
	The aggregate intrinsic value of options above represents the total pre-tax intrinsic value (the difference between the Corporation’s closing stock price on the last trading day of the third quarter of 2013 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on September 30, 2013. This amount changes based on the fair value of the Corporation’s stock.
	As of September 30, 2013, there was approximately $161,000 of total unrecognized compensation expense relating to unvested stock options.

	Note 4.  Recent Accounting Pronouncements
	In December 2012, the FASB issued an exposure draft of a proposed ASU of Topic 825-15, Credit Losses. The amendments of the proposed ASU would require all reporting entities, both public and nonpublic, to calculate impairment of existing financial assets on the basis of the current estimates of contractual cash flows not expected to be collected on the financial assets held at the reporting date. The proposed amendments would remove the existing “probable” threshold for recognizing credit losses and broaden the range of information that must be considered in measuring the allowance for expected credit losses. The estimate of expected credit losses would be based on relevant information about past events, including historical loss experience with similar assets, current conditions and reasonable and supportable forecasts that affect the future collectability of the assets’ remaining contractual cash flows.
	As a result of the proposed amendments, financial assets carried at amortized cost less an allowance would reflect the current estimate of the cash flows expected to be collected at the reporting date, and the income statement would reflect credit deterioration (or improvement) that has taken place during the period. For financial assets measured at fair value with changes in fair value recognized through other comprehensive income, the balance sheet would reflect the fair value, but the income statement would reflect credit deterioration (or improvement) that has taken place during the period. An entity, however, may choose to not recognize expected credit losses on financial assets measured at fair value, with changes in fair value recognized through other comprehensive income, if both (1) the fair value of the financial asset is greater than (or equal to) the amortized cost basis and (2) expected credit losses on the financial asset are insignificant. Currently, when credit losses are measured, an entity only considers past events and current conditions; the proposed amendments would broaden the information entities are required to consider to include historical loss experience with similar assets and reasonable and supportable forecasts that affect the expected collectability of the assets’ remaining contractual cash flows. It is expected that entities will be able to leverage their current risk monitoring systems in implementing the proposed approach, however, for the inputs used to estimate the expected credit loss approach. An entity would apply the proposed amendments with a cumulative-effect adjustment to the statement of financial position beginning in the first reporting period in which the guidance is effective.
	Both users and preparers of financial statements were requested to review and comment upon the exposure draft by April 30, 2013. The exposure draft does not include a proposed effective date of this guidance.
	In January 2013, the FASB issued ASU No. 2013-01, “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities,” which amended disclosures by requiring improved information about financial instruments and derivative instruments that are either offset on the balance sheet or subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset on the balance sheet. Reporting entities are required to provide both net and gross information for these assets and liabilities in order to enhance comparability between those entities that prepare their financial statements on the basis of international financial reporting standards ("IFRS"). Companies were required to apply the amendments for fiscal years beginning on or after January 1, 2013, and interim periods within those years.  The adoption of this accounting standard did not have a material impact on the Corporation's results of operations, financial position, or liquidity.
	In February 2013, the FASB issued ASU No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income," to improve the transparency of reporting these reclassifications. ASU No. 2013-02 does not amend any existing requirements for reporting net income or other comprehensive income in the financial statements. ASU No. 2013-02 requires an entity to disaggregate the total change of each component of other comprehensive income and separately present reclassification adjustments and current period other comprehensive income. The provisions of ASU No. 2013-02 also requires that entities present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line item affected by the reclassification. The Corporation adopted the provisions of ASU No. 2013-02 effective January 1, 2013. As the Corporation provided these required disclosures in the notes to the Consolidated Financial Statements, the adoption of ASU No. 2013-02 had no impact on the Corporation's consolidated statements of income and condition.

	Note 6.  Investment Securities
	The Corporation’s investment securities are classified as available-for-sale and held-to-maturity at September 30, 2013 and December 31, 2012. Investment securities available-for-sale are reported at fair value with unrealized gains or losses included in equity, net of tax. Accordingly, the carrying value of such securities reflects their fair value at the balance sheet date. Fair value is based upon either quoted market prices, or in certain cases where there is limited activity in the market for a particular instrument, assumptions are made to determine their fair value. See Note 8 of the Notes to Consolidated Financial Statements for a further discussion.
	Transfers of debt securities from the available-for-sale category to the held-to-maturity category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer remains in accumulated other comprehensive income and in the carrying value of the held-to-maturity investment security. Premiums or discounts on investment securities are amortized or accreted using the effective interest method over the life of the security as an adjustment of yield. Unrealized holding gains or losses that remain in accumulated other comprehensive income are amortized or accreted over the remaining life of the security as an adjustment of yield, offsetting the related amortization of the premium or accretion of the discount.
	The following tables present information related to the Corporation’s investment securities at September 30, 2013 and December 31, 2012.

During the nine months ended September 30, 2013, the Corporation reclassified at fair value approximately $75.7 million in available-for-sale investment securities to the held-to-maturity category. The net unrealized gains at date of transfer amounted to $63,000, remained in accumulated other comprehensive income and will be discounted over the remaining life of the securities as an adjustment of yield, offsetting the related amortization of the premium or accretion of the discount on the transferred securities. No gains or losses were recognized at the time of reclassification. Management considers the held-to-maturity classification of these investment securities to be appropriate as the Corporation has the positive intent and ability to hold these securities to maturity.
For the nine months ended September 30, 2013, proceeds of available-for-sale investment securities sold amounted to approximately $90.8 million.
The varying amount of sales from the available-for-sale portfolio over the past few years, and the significant volume of such sales in 2011, reflect the significant volatility present in the market. Given the historic low interest rates prevalent in the market, it is necessary for the Corporation to protect itself from interest rate exposure. Securities that once appeared to be sound investments can, after changes in the market, become securities that the Corporation has the flexibility to sell to avoid losses and mismatches of interest-earning assets and interest-bearing liabilities at a later time.
Gross gains and losses from the sales of investment securities for the three and nine month periods ended September 30, 2013 and 2012 were as follows:

The Corporation performs regular analysis on all its investment securities to determine whether a decline in fair value indicates that an investment is other-than-temporarily impaired in accordance with FASB ASC 320-10. FASB ASC 320-10 requires companies to record OTTI charges, through earnings, if they have the intent to sell, or if it is more likely than not that they will be required to sell, an impaired debt security before recovery of its amortized cost basis. If the Corporation intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, the OTTI is recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its estimated fair value at the balance sheet date. If the Corporation does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis, the OTTI is separated into the amount representing the credit loss and the amount related to all other factors. The amount of the OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment.
The Corporation’s assessment of whether an impairment is other than temporary includes factors such as whether the issuer has defaulted on scheduled payments, announced a restructuring and/or filed for bankruptcy, has disclosed severe liquidity problems that cannot be resolved, disclosed a deteriorating financial condition or sustained significant losses. The Corporation maintains a watch list for the identification and monitoring of securities experiencing problems that require a heightened level of review. This could result from credit rating downgrades.
The following table presents detailed information for each trust preferred security held by the Corporation at September 30, 2013 which has at least one rating below investment grade.

The Corporation owns one pooled trust preferred security (“Pooled TRUP”), which consists of securities issued by financial institutions and insurances companies. The Corporation holds the mezzanine tranche of the Pooled TRUP. Senior tranches generally are protected from defaults by over-collateralization and cash flow default protection provided by subordinated tranches, with senior tranches having the greatest protection and mezzanine tranches subordinated to the senior tranches. The Corporation’s analysis of the Pooled TRUP falls within the scope of EITF 99-20, ASC 320-40 and uses a discounted cash flow model to determine the total OTTI loss. The model considers the structure, term and the financial condition of the underlying issuers. Specifically, the model details interest rates, principal balances of note classes and underlying issuers and the allocation of the payments to the note classes according to a priority of payments specified in the offering circular and indenture. The current estimate of expected cash flows is based on the most recent trustee reports and other relevant market information including announcements of interest payment deferrals or defaults of underlying trust preferred security. Assumptions used in the model include defaults rates, default rate timing profiles and recovery rates. We assume no prepayments, as the Pooled TRUP was issued at comparatively tight spreads and as such, there is little incentive, if any, to prepay.
On September 25, 2013, the Pooled TRUP, ALESCO VII, incurred its sixteenth interruption of cash flow payments to date. Management reviewed the expected cash flow analysis and credit support to determine if it was probable that all principal and interest would be repaid, and recorded no other-than-temporary impairment charge for the nine months ended September 30, 2013 and September 30, 2012.
At September 30, 2013, excess subordination as a percentage of remaining performing collateral for the ALESCO Preferred Funding VII investments was -46.3 percent. Excess subordination is the amount of performing collateral above the amount of outstanding collateral underlying each class of the security. The excess subordination as a percent of remaining performing collateral reflects the difference between the performing collateral and the collateral underlying each security divided by the performing collateral. A negative number results when the paying collateral is less than the collateral underlying each class of the security. A low or negative number decreases the likelihood of full repayment of principal and interest according to original contractual terms.

The Corporation did not record other-than-temporary impairment charges relating to equity holdings in bank stocks for the nine months ended September 30, 2013 and September 30, 2012.
Temporarily Impaired Investments
For all securities, the Corporation does not believe that the unrealized losses, which were comprised of 147 investment securities as of September 30, 2013, represent an other-than-temporary impairment. The gross unrealized losses of $8.3 million associated with federal agency obligations, mortgage-backed securities, corporate bonds and tax-exempt securities are not considered to be other than temporary because these unrealized losses are related to changes in interest rates and do not affect the expected cash flows of the underlying collateral or issuer.
Factors affecting the market price include credit risk, market risk, interest rates, economic cycles, and liquidity risk. The magnitude of any unrealized loss may be affected by the relative concentration of the Corporation’s investment in any one issuer or industry. The Corporation has established policies to reduce exposure through diversification of concentration of the investment portfolio including limits on concentrations to any one issuer. The Corporation believes the investment portfolio is prudently diversified.
The decline in value is related to a change in interest rates and subsequent change in credit spreads required for these issues affecting market price. All issues are performing and are expected to continue to perform in accordance with their respective contractual terms and conditions. Short to intermediate average durations and in certain cases monthly principal payments should reduce further market value exposure to increases in rates.
The Corporation evaluates all securities with unrealized losses quarterly to determine whether the loss is other than temporary. Unrealized losses in the collateralized mortgage obligations category consist primarily of private issue collateralized mortgage obligations. Unrealized losses in the corporate debt securities category consist of losses on single issuer corporate trust preferred securities, pooled trust preferred securities and corporate debt securities issued by large financial institutions, insurance companies and other corporate issuers. The unrealized loss in equity securities consists of losses on other bank equities. The decline in fair value of $1.2 million is due in large part to the lack of an active trading market for these securities, changes in market credit spreads and rating agency downgrades. For collateralized mortgage obligations, management reviewed expected cash flows and credit support to determine if it was probable that all principal and interest would be repaid. None of the corporate issuers have defaulted on interest payments. Management concluded that these securities, other than the previously mentioned Pooled TRUP, were not other-than-temporarily impaired at September 30, 2013. Future deterioration in the cash flow on collateralized mortgage obligations or the credit quality of these large financial institution issuers of TRUP debt securities could result in impairment charges in the future.
In determining that the securities giving rise to the previously mentioned unrealized losses were not other-than-temporary, the Corporation evaluated the factors cited above, which the Corporation considers when assessing whether a security is other-than-temporarily impaired. In making these evaluations the Corporation must exercise considerable judgment. Accordingly there can be no assurance that the actual results will not differ from the Corporation’s judgments and that such differences may not require the future recognition of other-than-temporary impairment charges that could have a material effect on the Corporation’s financial position and results of operations. In addition, the value of, and the realization of any loss on, an investment security are subject to numerous risks as cited above.
The following tables indicate gross unrealized losses not recognized in income and fair value, aggregated by investment category and the length of time individual securities have been in a continuous unrealized loss position at September 30, 2013 and December 31, 2012:

Loans and the Allowance for Loan Losses [Abstract]	'
Loans and the Allowance for Loan Losses	'
	Note 7. Loans and the Allowance for Loan Losses
	Loans are stated at their principal amounts inclusive of net deferred loan origination fees. Interest income is credited as earned except when a loan becomes past due 90 days or more and doubt exists as to the ultimate collection of interest or principal; in those cases the recognition of income is discontinued. Loans that are past due 90 days or more that are both well secured and in the process of collection will remain on an accruing basis. When a loan is placed on non-accrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current income.
	Portfolio segments are defined as the level at which an entity develops and documents a systematic methodology to determine its allowance. Management has determined that the Corporation has two portfolio segments of loans and leases (commercial and consumer) in determining the allowance. Both quantitative and qualitative factors are used by management at the portfolio segment level in determining the adequacy of the allowance for the Corporation. Classes of loans and leases are a disaggregation of the Corporation's portfolio segments. Classes are defined as a group of loans and leases which share similar initial measurement attributes, risk characteristics, and methods for monitoring and assessing credit risk. Management has determined that the Corporation has five classes of loans and leases: commercial and industrial (including lease financing), commercial – real estate, construction, residential mortgage (including home equity) and installment.
	Generally, all classes of commercial and consumer loans and leases are placed on non-accrual status upon becoming contractually past due 90 days or more as to principal or interest (unless loans and leases are adequately secured by collateral, are in the process of collection, and are reasonably expected to result in repayment), when terms are renegotiated below market levels, or where substantial doubt about full repayment of principal or interest is evident. For certain installment loans the entire outstanding balance on the loan is charged-off when the loan becomes 60 days past due.
	Payments received on non-accrual loans are applied against principal. A loan may only be restored to an accruing basis when it again becomes well secured and in the process of collection or all past due amounts have been collected and six months of payments have been received to demonstrate that the borrower can continue to meet the loan terms. Loan origination fees and certain direct loan origination costs are deferred and recognized over the life of the loan as an adjustment to the loan’s yield using the level yield method.
	Impaired Loans
	The Corporation accounts for impaired loans in accordance with FASB ASC 310-10-35. The value of impaired loans is based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or at the fair value of the collateral if the loan is collateral dependent.
	A loan is considered impaired when, based on current information and events, it is probable that the Corporation will not be able to collect all amounts due from the borrower in accordance with the contractual terms of the loan, including scheduled interest payments.  The Corporation has defined its population of impaired loans to include all classes of non-accrual and troubled debt restructuring (“TDR”) loans. As part of the evaluation of impaired loans, the Corporation individually reviews for impairment all non-homogeneous loans (in each instance, above an established dollar threshold of $200,000) internally classified as substandard or below. Generally, smaller impaired non-homogeneous loans and impaired homogeneous loans are collectively evaluated for impairment.
	When a loan has been identified as being impaired, the amount of impairment is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral-dependent. If the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest, net of deferred loan fees or costs and unamortized premiums or discounts), an impairment is recognized by creating or adjusting an existing allocation of the allowance, or by recording a partial charge-off of the loan to its fair value. Interest payments made on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest income may be accrued or recognized on a cash basis.
	Loans Modified in a Troubled Debt Restructuring
	Loans are considered to have been modified in a TDR when due to a borrower's financial difficulties, the Corporation makes certain concessions to the borrower that it would not otherwise consider. Modifications may include interest rate reductions, principal or interest forgiveness, forbearance, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Generally, a non-accrual loan that has been modified in a TDR remains on non-accrual status for a period of six months to demonstrate that the borrower is able to meet the terms of the modified loan. However, performance prior to the modification, or significant events that coincide with the modification, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status at the time of loan modification or after a shorter performance period. If the borrower's ability to meet the revised payment schedule is uncertain, the loan remains on non-accrual status.
	Reserve for Credit Losses
	The Corporation's reserve for credit losses is comprised of two components, the allowance for loan losses and the reserve for unfunded commitments (the "Unfunded Commitments").
	Allowance for Loan Losses
	The allowance for loan losses is maintained at a level determined adequate to provide for probable loan losses. The allowance is increased by provisions charged to operations and reduced by loan charge-offs, net of recoveries. The allowance is based on management’s evaluation of the loan portfolio considering economic conditions, the volume and nature of the loan portfolio, historical loan loss experience and individual credit situations.
	Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for loan losses. In connection with the determination of the allowance for loan losses, management obtains independent appraisals for significant properties.
	The ultimate collectability of a substantial portion of the Corporation’s loan portfolio is susceptible to changes in the real estate market and economic conditions in the State of New Jersey and the impact of such conditions on the creditworthiness of the borrowers.
	Management believes that the allowance for loan losses is adequate. Management uses available information to recognize loan losses; however, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s allowance for loan losses. Such agencies may require the Corporation to recognize additions to the allowance based on their judgments about information available to them at the time of their examinations.
	Reserve for Unfunded Commitments
	The reserve for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities and is included in other liabilities in the consolidated statements of condition. The determination of the adequacy of the reserve is based upon an evaluation of the unfunded credit facilities, including an assessment of historical commitment utilization experience, and credit risk. Net adjustments to the reserve for unfunded commitments are included in other expense.
	Risk Related to Representation and Warranty Provisions
	The Corporation sells residential mortgage loans in the secondary market primarily to Fannie Mae. The Corporation sells residential mortgage loans to Fannie Mae that include various representations and warranties regarding the origination and characteristics of the residential mortgage loans. Although the specific representations and warranties vary, they typically cover ownership of the loan, validity of the lien securing the loan, the absence of delinquent taxes or liens against the property securing the loan, compliance with loan criteria set forth in the applicable agreement, compliance with applicable federal, state, and local laws, and other matters.
	As of September 30, 2013, the unpaid principal balance of the Corporation’s portfolio of residential mortgage loans sold to Fannie Mae was $8.5 million. These loans are generally sold on a non-recourse basis. The agreements under which the Corporation sells residential mortgage loans require the Corporation to deliver various documents to the investor or its document custodian. Although these loans are primarily sold on a non-recourse basis, the Corporation may be obligated to repurchase residential mortgage loans where required documents are not delivered or are defective. Investors may require the immediate repurchase of a mortgage loan when an early payment default discovered in an underwriting review reveals significant underwriting deficiencies, even if the mortgage loan has subsequently been brought current. As of September 30, 2013, there were no pending repurchase requests related to representation and warranty provisions.
	Composition of Loan Portfolio
	The following table sets forth the composition of the Corporation’s loan portfolio, including net deferred fees and costs, at September 30, 2013 and December 31, 2012:
		September		December
		30,		31,
		2013		2012
		(in thousands)
	Commercial and industrial	$	229,212	$	181,682
	Commercial real estate		531,674		497,392
	Construction		42,727		40,277
	Residential mortgage		152,934		169,094
	Installment		789		1,104
	Subtotal		957,336		889,549
	Net deferred loan costs		156		123
	Total loans	$	957,492	$	889,672
	At September 30, 2013 and December 31, 2012, loans to executive officers and directors aggregated approximately $22,456,000 and $18,977,000, respectively. During the nine months ended September 30, 2013, the Corporation made new loans and advances to executive officers and directors in the amount of $11,322,000.  Payments by such persons during the nine months ended September 30, 2013 aggregated $7,843,000. Management is of the opinion that the above loans were made on the same terms and conditions as those prevailing for comparable transactions with non-related borrowers.
	At September 30, 2013 and December 31, 2012, loan balances of approximately $538.1 million and $532.8 million, respectively, were pledged to secure borrowings from the Federal Reserve Bank of New York and the Federal Home Loan Bank of New York.
	The following table presents information about loan receivables on non-accrual status at September 30, 2013 and December 31, 2012:
	Loans Receivable on Non-Accrual Status
		September 30,		December 31,

	Construction		—		319
	Residential mortgage		1,772		2,729
	Total loans receivable on non-accrual status	$	2,032	$	3,618
	The amount of interest income that would have been recorded on non-accrual loans during the nine months ended September 30, 2013 and the year ended December 31, 2012, had payments remained in accordance with the original contractual terms, was $69,000 and $187,000, respectively.
	The Corporation continuously monitors the credit quality of its loans receivable. In addition to its internal staff, the Corporation utilizes the services of a third party loan review firm to rate the credit quality of its loans receivable. Credit quality is monitored by reviewing certain credit quality indicators. Assets classified “Pass” are deemed to possess average to superior credit quality, requiring no more than normal attention. Assets classified as “Special Mention” have generally acceptable credit quality yet possess higher risk characteristics/circumstances than satisfactory assets. Such conditions include strained liquidity, slow pay, stale financial statements, or other conditions that require more stringent attention from the lending staff. These conditions, if not corrected, may weaken the loan quality or inadequately protect the Corporation’s credit position at some future date. Assets are classified “Substandard” if the asset has a well defined weakness that requires management’s attention to a greater degree than for loans classified special mention. Such weakness, if left uncorrected, could possibly result in the compromised ability of the loan to perform to contractual requirements. An asset is classified as “Doubtful” if it is inadequately protected by the net worth and/or paying capacity of the obligor or of the collateral, if any, that secures the obligation. Assets classified as doubtful include assets for which there is a “distinct possibility” that a degree of loss will occur if the inadequacies are not corrected. All loans past due 90 days or more and all impaired loans are included in the appropriate category below. The following table presents information, excluding net deferred costs, about the Corporation’s loan credit quality at September 30, 2013 and December 31, 2012:

The Corporation’s allowance for loan losses is analyzed quarterly. Many factors are considered, including growth in the portfolio, delinquencies, nonaccrual loan levels, and other factors inherent in the extension of credit. There have been no material changes to the allowance for loan loss methodology as disclosed in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2012.
A summary of the activity in the allowance for loan losses is as follows:

At September 30, 2013, there were no commitments to lend additional funds to borrowers whose loans were on non-accrual status or were contractually past due in excess of 90 days and still accruing interest, or whose terms have been modified in troubled debt restructurings.
The policy of the Corporation generally is to grant commercial, mortgage and installment loans to New Jersey residents and businesses within its market area. The borrowers’ abilities to repay their obligations are dependent upon various factors, including the borrowers’ income and net worth, cash flows generated by the borrowers’ underlying collateral, value of the underlying collateral, and priority of the lender’s lien on the property. Such factors are dependent upon various economic conditions and individual circumstances beyond the control of the Corporation. The Corporation is therefore subject to risk of loss. The Corporation believes its lending policies and procedures adequately minimize the potential exposure to such risks and that adequate provisions for loan losses are provided for all known and inherent risks. Collateral and/or personal guarantees are required for virtually all loans.
The Corporation added no new troubled debt restructurings during the three and nine months ended September 30, 2013.
Loans modified in a troubled debt restructuring totaled $2.8 million at September 30, 2013, of which $1.1 million were on non-accrual status. The remaining loans modified were current at the time of the restructuring and have complied with the terms of their restructure agreement. At December 31, 2012, loans modified in a troubled debt restructuring totaled $8.3 million, of which $1.5 million were on non-accrual status. The remaining loans modified were current at the time of the restructuring and have complied with the terms of their restructure agreement.
In an effort to proactively manage delinquent loans, the Corporation has selectively extended to certain borrowers concessions such as rate reductions, extension of maturity dates, principal or interest forgiveness, adjusted repayment terms, forbearance agreements, or combinations of two or more of these concessions. As of September 30, 2013, loans on which concessions were made with respect to adjusted repayment terms amounted to $1.5 million. Loans on which combinations of two or more concessions were made amounted to $1.3 million. The concessions granted included principal concessions, rate reduction, adjusted repayment, extended maturity and payment deferral.

Fair Value Measurements and Fair Value of Financial Instruments	'
	Note 8.  Fair Value Measurements and Fair Value of Financial Instruments
	Fair Value Measurements
	Management uses its best judgment in estimating the fair value of the Corporation’s financial and non-financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial and non-financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Corporation could have realized in a sale transaction on the dates indicated. The estimated fair value amounts have been measured as of the respective period-end dates indicated herein and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial and non-financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period-end.
	U.S. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:
		·	Level 1: Unadjusted exchange quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
		·	Level 2: Quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
		·	Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (for example, supported with little or no market activity).
	An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	The following information should not be interpreted as an estimate of the fair value of the entire Corporation since a fair value calculation is only provided for a limited portion of the Corporation’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Corporation’s disclosures and those of other companies may not be meaningful. The following methods and assumptions were used to estimate the fair values of the Corporation’s assets measured at fair value on a recurring basis at September 30, 2013 and December 31, 2012.
	Investment Securities Available-for-Sale
	Where quoted prices are available in an active market, investment securities are classified in Level 1 of the valuation hierarchy. Level 1 inputs include investment securities that have quoted prices in active markets for identical assets. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. Examples of instruments, which would generally be classified within Level 2 of the valuation hierarchy, include municipal bonds and certain agency collateralized mortgage obligations. In certain cases where there is limited activity in the market for a particular instrument, assumptions must be made to determine their fair value and are classified as Level 3. Due to the inactive condition of the markets amidst the financial crisis, the Corporation treated certain investment securities as Level 3 assets in order to provide more appropriate valuations. For assets in an inactive market, the infrequent trades that do occur are not a true indication of fair value. When measuring fair value, the valuation techniques available under the market approach, income approach and/or cost approach are used. The Corporation’s evaluations are based on market data and the Corporation employs combinations of these approaches for its valuation methods depending on the asset class. In certain cases where there were limited or less transparent information provided by the Corporation’s third-party pricing service, fair value was estimated by the use of secondary pricing services or through the use of non-binding third-party broker quotes.
	On a quarterly basis, management reviews the pricing information received from the Corporation’s third-party pricing service. This review process includes a comparison to non-binding third-party broker quotes, as well as a review of market-related conditions impacting the information provided by the Corporation’s third-party pricing service.
	Management primarily identifies investment securities which may have traded in illiquid or inactive markets by identifying instances of a significant decrease in the volume and frequency of trades, relative to historical levels, as well as instances of a significant widening of the bid-ask spread in the brokered markets. Investment securities that are deemed to have been trading in illiquid or inactive markets may require the use of significant unobservable inputs. For example, management may use quoted prices for similar investment securities in the absence of a liquid and active market for the securities being valued. As of September 30, 2013 and December 31, 2012, management made adjustments to prices provided by the third-party pricing service as a result of illiquid or inactive markets.
	At September 30, 2013 and December 31, 2012, the Corporation’s pooled trust preferred security, ALESCO VII, was classified as Level 3. Market pricing for the Level 3 security varied widely from one pricing service to another based on the lack of trading. As such, the security was not considered to have readily observable market data that was accurate to support a fair value as prescribed by FASB ASC 820-10-05. The Corporation determined that significant adjustments using unobservable inputs are required to determine fair value at the measurement date.
	The Corporation determined that an income approach valuation technique (present value technique) that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs will be equally or more representative of fair value than the market approach valuation technique used at the prior measurement dates. As a result, the Corporation used the discount rate adjustment technique to determine fair value.
	The fair value of private label CMO was determined by discounting the expected cash flows over the life of the security. The discount rate was determined by deriving a discount rate when the markets were considered more active for this type of security. To this estimated discount rate, additions were made for more liquid markets and increased credit risk as well as assessing the risks in the security, such as default risk and severity risk. However, the private label CMO had interruptions of its scheduled principal payments and the Corporation recorded a net settlement principal loss of $24,000 for the nine months ended September 30, 2013; this security was sold at its book value on January 4, 2013.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	For financial assets and liabilities measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used at September 30, 2013 and December 31, 2012 are as follows:

The fair values used by the Corporation are obtained from an independent pricing service and represent either quoted market prices for the identical securities (Level 1 inputs) or fair values determined by pricing models using a market approach that considers observable market data, such as interest rate volatilities, LIBOR yield curve, credit spreads and prices from market makers and live trading systems (Level 2). The fair value of the obligations of states and political subdivisions securities was measured at fair value using Level 1 inputs at December 31, 2012 represented the purchase price of the securities since they were acquired near year-end 2012.
The following tables present the changes in investment securities available-for-sale with significant unobservable inputs (Level 3) for the three and nine months ended September 30, 2013 and 2012.

For the nine months ended September 30, 2013, there were no transfers of investment securities available-for-sale into or out of Level 1, Level 2, or Level 3 assets, except for securities purchased at year end included in Level 1, representing purchase prices, which subsequently were evaluated and placed in the appropriate Level depending on the observable inputs.
Assets Measured at Fair Value on a Non-Recurring Basis
For assets measured at fair value on a non-recurring basis, the unobservable inputs used to derive fair value measurements at September 30, 2013 and December 31, 2012 were as follows:
	Impaired Loans		Valuation Techniques	Range of Unobservable Inputs
	Residential		Appraisals of collateral value	Adjustment for age of comparable sales, generally a decline of 0-25%
	Commercial		Discounted cash flow model	Discount rate from 0% to 6%
	Commercial real estate		Appraisals of collateral value	Market capitalization rates between 8% to 12%. Market rental rates for similar properties
	Construction		Appraisals of collateral value	Adjustment for age comparable sales. Generally a decline of 5% to no change
	Other Real Estate Owned
	Residential		Appraisals of collateral value	Adjustment for age of comparable sales, generally a decline of 0-25% and estimated selling costs of 6-8%
	Commercial		Appraisals of collateral value	Adjustment for age of comparable sales, generally a decline of 15% to no change and estimated selling costs of 6-8%

The following methods and assumptions were used to estimate the fair values of the Corporation’s assets measured at fair value on a non-recurring basis at September 30, 2013 and December 31, 2012.
Impaired Loans. The value of an impaired loan is measured based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if the loan is collateral dependent. Smaller balance homogeneous loans that are collectively evaluated for impairment, such as residential mortgage loans and installment loans, are specifically excluded from the impaired loan portfolio. The Corporation’s impaired loans are primarily collateral dependent. Impaired loans are individually assessed to determine that each loan’s carrying value is not in excess of the fair value of the related collateral or the present value of the expected future cash flows. Impaired loans at September 30, 2013 that required a valuation allowance during 2013 were $1.3 million with a related valuation allowance of $219,000 compared to $5.4 million with a related valuation allowance of $645,000 at December 31, 2012. Impaired loans that required a valuation allowance were $6.9 million with a related valuation allowance of $758,000 during the nine months ended September 30, 2012. Impaired loans of $1.5 million had no recorded valuation allowance for December 31, 2012.
Fair Value of Financial Instruments
Other Real Estate Owned.  Other real estate owned (“OREO”) is measured at fair value less costs to sell, generally a decline of 0-25% for residential OREO and a decline of 15% to no change for commercial OREO. The Corporation believes that the fair value component in its valuation follows the provisions of FASB ASC 820-10-05. The fair value of OREO is determined by sales agreements or appraisals by qualified licensed appraisers approved and hired by the Corporation. Costs to sell associated with OREO is based on estimation per the terms and conditions of the sales agreements or appraisals.
FASB ASC 825-10 requires all entities to disclose the estimated fair value of their financial instrument assets and liabilities. For the Corporation, as for most financial institutions, the majority of its assets and liabilities are considered financial instruments as defined in FASB ASC 825-10. Many of the Corporation’s financial instruments, however, lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction. It is also the Corporation’s general practice and intent to hold its financial instruments to maturity and not to engage in trading or sales activities except for loans held-for-sale and investment securities available-for-sale. Therefore, significant estimations and assumptions, as well as present value calculations, were used by the Corporation for the purposes of this disclosure.
Investment Securities Held-to-Maturity. The fair value of the Corporation’s investment securities held-to-maturity was primarily measured using information from a third-party pricing service. If quoted prices were not available, fair values were estimated primarily by obtaining quoted prices for similar assets in active markets or through the use of pricing models. In cases where there may be limited or less transparent information provided by the Corporation’s third-party pricing service, fair value may be estimated by the use of secondary pricing services or through the use of non-binding third-party broker quotes.
Loans Held-for-Sale. Fair value is estimated using the prices of the Corporation’s existing commitments to sell such loans and/or the quoted market price for commitments to sell similar loans.
Loans. The fair value of the Corporation’s loans was estimated by discounting the expected future cash flows using the current interest rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Loans were segregated by types such as commercial, residential and consumer loans. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments.
Non  Interest-Bearing Deposits. The fair value for non interest-bearing deposits is equal to the amount payable on demand at the reporting date.
Interest-Bearing Deposits. The fair values of the Corporation’s interest-bearing deposits were estimated using discounted cash flow analyses. The discounted rates used were based on rates currently offered for deposits with similar remaining maturities. The fair values of the Corporation’s interest-bearing deposits do not take into consideration the value of the Corporation’s long-term relationships with depositors, which may have significant value.
Term Borrowings and Subordinated Debentures. The fair value of the Corporation’s long-term borrowings and subordinated debentures were calculated using a discounted cash flow approach and applying discount rates currently offered based on weighted remaining maturities.
Accrued Interest Receivable/Payable. The carrying amounts of accrued interest approximate fair value resulting in a Level 2 or Level 3 classification based on the level of the asset or liability with which the accrual is associated.
The following presents the carrying amount, fair value, and placement in the fair value hierarchy of the Corporation’s financial instruments as of September 30, 2013 and December 31, 2012.

Net Investment in Direct Financing Lease	'
	Note 9.  Net Investment in Direct Financing Lease
	During the second quarter of 2010, the Corporation entered into a lease of its former operations facility under a direct financing lease. The lease has a 15 year term with no renewal options. According to the terms of the lease, the lessee has an obligation to purchase the property underlying the lease in either year seven (7), ten (10) or fifteen (15) at predetermined prices for those years as provided in the lease. The structure of the minimum lease payments and the purchase prices as provided in the lease provide an inducement to the lessee to purchase the property in year seven (7).
	At September 30, 2013 and December 31, 2012, the net investment in direct financing lease consists of a minimum lease receivable of $4,537,000 and $4,699,000, respectively, and unearned interest income of $781,000 and $928,000, respectively, for a net investment in direct financing lease of $3,756,000 and $3,771,000, respectively. The net investment in direct financing lease is carried as a component of loans in the Corporation’s consolidated statements of condition.
	Minimum future lease receipts of the direct financing lease are as follows:

Under these arrangements, the Corporation may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Corporation to repurchase the assets. The obligation to repurchase the securities is reflected as a liability in the Corporation’s consolidated statement of condition, while the securities underlying the securities sold under agreements to repurchase remain in the respective asset accounts and are delivered to and held as collateral by third party trustees. At September 30, 2013 and December 31, 2012, securities sold under agreements to repurchase had a weighted average interest rate of 5.90 percent and 5.54 percent, respectively, and are contractually scheduled for repayment as follows:

Subordinated Debentures [Abstract]	'
Subordinated Debentures	'
	Note 13.  Subordinated Debentures
	During 2003, the Corporation formed a statutory business trust, which exists for the exclusive purpose of (i) issuing trust securities representing undivided beneficial interests in the assets of the trust; (ii) investing the gross proceeds of the trust securities in junior subordinated deferrable interest debentures (subordinated debentures) of the Corporation; and (iii) engaging in only those activities necessary or incidental thereto. These subordinated debentures and the related income effects are not eliminated in the consolidated financial statements as the statutory business trust is not consolidated in accordance with FASB ASC 810-10. Distributions on the subordinated debentures owned by the subsidiary trusts below have been classified as interest expense in the Consolidated Statements of Income.
	The characteristics of the business trust and capital securities have not changed with the deconsolidation of the trust. The capital securities provide an attractive source of funds since they constitute Tier 1 capital for regulatory purposes and have the same tax advantages as debt for Federal income tax purposes.
	The subordinated debentures are redeemable in whole or part prior to maturity on January 23, 2034. The floating interest rate on the subordinated debentures is three-month LIBOR plus 2.85 percent and resets quarterly. The rate at September 30, 2013 was 3.12 percent.

Stockholders' Equity	'
	Note 14.  Stockholders’ Equity
	On January 12, 2009, the Corporation issued $10 million in nonvoting fixed rate cumulative perpetual preferred stock, Series A to the U.S. Department of Treasury (“Treasury”) under its Capital Purchase Program. As part of the transaction, the Corporation also issued warrants to the Treasury to purchase 173,410 shares of common stock of the Corporation at an exercise price of $8.65 per share. As a result of the successful completion of the Corporation’s rights offering in October 2009, the number of shares underlying the warrants held by the U.S. Treasury was reduced to 86,705 shares, or 50 percent of the original 173,410 shares, as outlined by the provisions of the Capital Purchase Program.
	On September 15, 2011, the Corporation issued $11.25 million in nonvoting senior preferred stock to the Treasury under the Small Business Lending Fund Program (“SBLF Program”). Under the Securities Purchase Agreement, the Corporation issued to the Treasury a total of 11,250 shares of the Corporation’s Senior non-cumulative perpetual preferred stock, Series B, having a liquidation value of $1,000 per share. Simultaneously, using the proceeds from the issuance of the Series B Preferred Stock, the Corporation redeemed from the Treasury, all 10,000 outstanding shares of its fixed rate cumulative perpetual preferred stock, Series A, liquidation amount $1,000 per share, for a redemption price of $10,041,667, including accrued but unpaid dividends up to the date of redemption. The investment in the SBLF program provided the Corporation with approximately $1.25 million additional Tier 1 capital. The capital received under the program enables the Corporation to continue to serve its small business clients through the commercial lending program.
	On December 7, 2011, the Corporation repurchased the warrants issued on January 12, 2009 to the Treasury as part of its participation in the Treasury’s TARP Capital Purchase Program. In the repurchase, the Corporation paid the Treasury $245,000 for the warrants.

	On October 30 and 31, 2013, the Corporation modified the terms of $40 million in FHLB advances within its long-term borrowings. The modifications resulted in a reduction of the interest rates on these funds, extension of their maturity dates to seven years from the date of modifications, and conversion of the advances to non-putable for three years. After the modifications, the weighted average interest rate on these borrowings declined by 52 basis points to 3.43 percent. There were no gains, losses, penalties or fees incurred in the modification transactions.

Basis of Presentation [Abstract]	'
Consolidation	'
	The consolidated financial statements of Center Bancorp, Inc. (the “Parent Corporation”) are prepared on the accrual basis and include the accounts of the Parent Corporation and its wholly-owned subsidiary, Union Center National Bank (the “Bank” and, collectively with the Parent Corporation and the Parent Corporation’s other direct and indirect subsidiaries, the “Corporation”). All significant intercompany accounts and transactions have been eliminated from the accompanying consolidated financial statements.
Use of Estimates	'
	In preparing the consolidated financial statements, management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of condition and that affect the results of operations for the periods presented. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to change in the near term relate to the determination of the allowance for loan losses, the other-than-temporary impairment evaluation of securities, the evaluation of the impairment of goodwill and the evaluation of deferred tax assets.
Basis of Accounting	'
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”).

Share-based Compensation Arrangement by Share-based Payment Award, Award Vesting Period	'3 years 7 days	'
Share-based Compensation Arrangement by Share-based Payment Award, Award Vesting Rights	'The Corporation maintains two stock-based compensation plans from which new grants could be issued. The Corporation’s stock-based compensation plans permit Parent Corporation common stock to be issued to key employees and directors of the Corporation and its subsidiaries. The options granted under the plans are intended to be either incentive stock options or non-qualified options. Under the 2009 Equity Incentive Plan, a total of 363,081 shares are available for grant and issuance as of September 30, 2013. Under the 2003 Non-Employee Director Stock Option Plan, a total of 380,644 shares remain available for grant and issuance under the plan as of September 30, 2013. Such shares may be treasury shares, newly issued shares or a combination thereof. Options have been granted to purchase common stock principally at the fair market value of the stock at the date of grant. Options are exercisable over a three year vesting period starting one year after the date of grant and generally expire ten years from the date of grant. Stock-based compensation expense for share-based payment awards is based on the grant date fair value estimated on the date of grant. The Corporation recognizes compensation costs for those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of three years. The Corporation estimates the forfeiture rate based on its historical experience during the preceding seven fiscal years.	'
