	Organization and Operations
	References to the terms “we”, “our”, “us”, “Stonegate” or the “Company” used throughout these Notes to Unaudited Consolidated Financial Statements refer to Stonegate Mortgage Corporation and, unless the context otherwise requires, its wholly-owned subsidiaries. The Company was initially incorporated in the State of Indiana in January 2005. As a result of an acquisition and subsequent merger with Swain Mortgage Company in 2009, the Company is now an Ohio corporation. The Company’s headquarters is in Indianapolis, Indiana.
	The Company is a non-bank integrated mortgage company focused on the U.S. residential mortgage market. The Company originates, acquires, sells, finances and services residential mortgage loans. The Company predominantly sells mortgage loans to the Federal National Mortgage Association (“Fannie Mae” or “FNMA”), to the Federal Home Loan Mortgage Corporation (“Freddie Mac” or “FHLMC”), to financial institution secondary market investors and in Government National Mortgage Association (“Ginnie Mae” or “GNMA”) pools of mortgage backed securities (“MBS”). Both FNMA and FHLMC are considered government-sponsored enterprises ("GSEs"). The Company’s integrated and scalable residential mortgage banking platform enables us to efficiently and effectively originate, acquire, sell, finance and service residential mortgage loans. The Company’s platform and operating model provides its constituents visibility and access to essential data, documents and analytics related to the loan and originator performance over time. The Company also provides warehouse financing through its NattyMac, LLC subsidiary to third party correspondent customers. The Company’s principal sources of revenue include (i) gain on sale of mortgage loans from loan securitizations and whole loan sales, and fee income from originations, (ii) fee income from loan servicing, and (iii) fee and net interest income from its financing facilities.

	Basis of Presentation
	The accompanying unaudited consolidated financial statements include the accounts of Stonegate and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The Company has omitted certain financial disclosures that would substantially duplicate the disclosures in its audited consolidated financial statements as of and for the year ended December 31, 2013, unless the information contained in those disclosures materially changed or is required by GAAP. In the opinion of management, all adjustments, including normal recurring adjustments, necessary for a fair statement of the consolidated financial statements as of and for the three months ended March 31, 2014 and 2013 have been recorded. All intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2014. These unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2013 included in its 2013 Annual Report on Form 10-K.
	In the normal course of business, companies in the mortgage banking industry encounter certain economic and regulatory risks. Economic risks include interest rate risk and credit risk. The Company is subject to interest rate risk to the extent that in a rising interest rate environment, the Company may experience a decrease in loan production, as well as decreases in the value of mortgage loans held for sale and in commitments to originate loans, which may negatively impact the Company’s operations. Conversely, in a decreasing interest rate environment, the value of the Company’s mortgage servicing rights ("MSRs") may decrease, which could negatively impact the Company’s operations. Credit risk is the risk of default that may result from the borrowers’ inability or unwillingness to make contractually required payments during the period in which loans are being held for sale.
	On May 14, 2013, the Company granted a stock dividend of 12.861519 shares of common stock for each share of common stock held as of that date, which was determined to be in substance a stock split for accounting and financial reporting purposes. All actual share, weighted-average share and per share amounts and all references to stock compensation data and prices of the Company’s common stock have been adjusted to reflect this stock split for all periods presented.

	Acquisition of Medallion Mortgage Company
	On February 4, 2014, in the continuing effort to expand retail originations, the Company completed its acquisition of Medallion Mortgage Company ("Medallion"), a residential mortgage originator based in southern California. Medallion services customers with an extensive portfolio of residential real estate loan programs and has 10 offices along the southern and central coast of California, Utah and a new operations center in Ventura, California. In the acquisition of Medallion, the Company agreed to purchase certain assets, assume certain liabilities and offer employment to certain employees.
	The acquisition of Medallion was accounted for as a business combination. The following table summarizes the total consideration transferred to acquire Medallion and the fair values of the assets acquired and liabilities assumed on the acquisition date:
	Consideration:
	Cash consideration	$	258
	Fair value of contingent consideration	603
	Total consideration	861
	Fair value of net assets acquired:
	Property and equipment	190
	Other assets	94
	Accounts payable and accrued expenses	(50		)
	Total fair value of net assets acquired	234
	Goodwill	$	627
	Acquisition-related expenses 1	$	49
	1 Legal and miscellaneous expenses classified as general and administrative expenses
	The excess of the aggregate consideration transferred over the fair value of the identified net assets acquired resulted in tax-deductible goodwill of $627 as of March 31, 2014. Goodwill recognized from the acquisition of Medallion primarily relates to the expected future growth of Medallion's business.
	As part of the acquisition of Medallion, the Company agreed to pay Medallion's seller a deferred purchase price, which payment is contingent upon Medallion achieving certain predetermined minimum mortgage loan origination goals during the two year period following the acquisition date (the "earnout"). If such goals are met by Medallion, the Company will pay the seller annual payments equal to a multiple of the actual total mortgage loan volume of Medallion. The earnout is uncapped in amount. The fair value of the earnout was estimated to be approximately $603 as of the acquisition date and was estimated using a calibrated Monte-Carlo simulation. The fair value was primarily based on (i) the Company’s estimate of the mortgage loan origination volume of Medallion over the two year earnout period, an asset volatility factor of 16.90% and (iii) a discount rate of 6.05%. The Company estimated the fair value of the earnout as of March 31, 2014 to approximate its acquisition date fair value as there were no significant changes in the Company's estimate of future mortgage loan origination volume, volatility factor or the discount rate used to determine the fair value of the earnout.

	The Company has exposure to credit loss in the event of contractual non-performance by its trading counterparties and counterparties to the over-the-counter derivative financial instruments that the Company uses in its rate risk management activities. The Company manages this credit risk by selecting only counterparties that the Company believes to be financially strong, spreading the credit risk among many such counterparties, by placing contractual limits on the amount of unsecured credit extended to any single counterparty and by entering into netting agreements with the counterparties, as appropriate.
	The Company has entered into agreements with derivative counterparties which include netting arrangements whereby the counterparties are entitled to settle their positions on a net basis. In certain circumstances, the Company is required to provide certain derivative counterparties collateral against derivative financial instruments. As of March 31, 2014 and December 31, 2013, counterparties held $1,159 and $730, respectively, of the Company’s cash and cash equivalents in margin accounts as collateral (which is classified as "Restricted cash" on the Company's consolidated balance sheets), after which the Company was in a net credit loss position of $2,618 and $3,520 at March 31, 2014 and December 31, 2013, respectively, to those counterparties. For the three months ended March 31, 2014 and 2013, the Company incurred no credit losses due to non-performance of any of its counterparties.

The mortgage loans pledged as collateral must equal at least 100% of the related outstanding borrowings under the mortgage funding arrangements. The outstanding borrowings are monitored and the Company is required to deliver additional collateral if the amount of the outstanding borrowings exceeds the fair value of the pledged mortgage loans. As of March 31, 2014, the Company had pledged $800,056 in fair value of mortgage loans held for sale as collateral to secure debt under its mortgage funding arrangements, with the remaining $34,859 of mortgage loans held for sale funded with the Company’s excess cash.

	Mortgage Servicing Rights
	The Company sells residential mortgage loans in the secondary market and typically retains the right to service the loans sold. Upon sale, an MSR asset is capitalized, which represents the current fair value of the future net cash flows expected to be realized for performing servicing activities. The Company also purchases MSRs directly from third parties.
	The Company’s total mortgage servicing portfolio as of March 31, 2014 and December 31, 2013 is summarized as follows (based on the UPB of the underlying mortgage loans):
		March 31, 2014			December 31, 2013

	Fair Value Measurements
	The Company uses fair value measurements in fair value disclosures and to record certain assets and liabilities at fair value on a recurring basis, such as MSRs, derivatives and loans held for sale, or on a nonrecurring basis, such as when measuring intangible assets and long-lived assets. The Company has elected fair value accounting for loans held for sale to more closely align the Company’s accounting with its interest rate risk strategies without having to apply the operational complexities of hedge accounting.
	The Company groups its assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
	Level Input:	Input Definition:
	Level 1	Unadjusted, quoted prices in active markets for identical assets or liabilities.
	Level 2	Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing an asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets and liabilities, interest rates, prepayment speeds, credit risk and others.
	Level 3	Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity), unobservable inputs may be used. Unobservable inputs reflect the Company's own assumptions about the factors that market participants would use in pricing the asset or liability, and are based on the best information available in the circumstances.
	An asset 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.
	While the Company believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methods or assumptions to estimate the fair value of certain financial statement items could result in a different estimate of fair value at the reporting date. Those estimated values may differ significantly from the values that would have been used had a readily available market for such items existed, or had such items been liquidated, and those differences could be material to the consolidated financial statements.
	Management incorporates lack of liquidity into its fair value estimates based on the type of asset or liability measured and the valuation method used. The Company uses discounted cash flow techniques to estimate fair value. These techniques incorporate forecasting of expected cash flows discounted at appropriate market discount rates that are intended to reflect the lack of liquidity in the market.
	The following describes the methods used in estimating the fair values of certain financial statement items:
	Mortgage Loans Held for Sale: The Company's mortgage loans held for sale at fair value are saleable into the secondary mortgage markets and their fair values are estimated using quoted market or contracted prices or market price equivalents.
	Derivative Financial Instruments: The Company estimates the fair value of interest rate lock commitments based on the value of the underlying mortgage loan, quoted MBS prices and estimates of the fair value of the MSRs and the probability that the mortgage loan will fund within the terms of the interest rate lock commitment. The Company estimates the fair value of forward sales commitments based on quoted MBS prices.
	Mortgage Servicing Rights: The Company uses a discounted cash flow approach to estimate the fair value of MSRs. This approach consists of projecting servicing cash flows discounted at a rate that management believes market participants would use in their determinations of value. The key assumptions used in the estimation of the fair value of MSRs include prepayment speeds, discount rates, default rates, cost to service, contractual servicing fees and escrow earnings.

Transfers between levels, if any, are recorded as of the beginning of the reporting period. During the three months ended March 31, 2014 and 2013, there were no transfers between levels.
Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. As disclosed in Note 4, "Business Combinations," we completed our acquisition of Medallion on February 4, 2014. The values of the net assets acquired in the acquisition of Medallion and resulting goodwill were recorded at fair value using Level 3 inputs. Refer to Note 4, "Business Combinations," for further information regarding the methodology and key assumptions used in the acquisition date fair value estimates.
Fair Value of Other Financial Instruments
As of March 31, 2014 and December 31, 2013, all financial instruments were either recorded at fair value or the carrying value approximated fair value. For financial instruments that were not recorded at fair value, such as cash, restricted cash, servicing advances, secured borrowings, warehouse and operating lines of credit, accounts payable and accrued expenses, their carrying values approximated fair value due to the short-term nature of such instruments.

Transfers and Servicing [Abstract]	'
Transfers and Servicing of Financial Assets	'
	Transfers and Servicing of Financial Assets
	Residential mortgage loans are primarily sold to FNMA or FHLMC or transferred into pools of GNMA MBS. The Company has continuing involvement in mortgage loans sold through servicing arrangements and the liability for loan indemnifications and repurchases under the representation and warranties it makes to the investors and insurers of the loans it sells. The Company is exposed to interest rate risk through its continuing involvement with mortgage loans sold, including the MSRs, as the value of the asset fluctuates as changes in interest rates impact borrower prepayment.
	All loans are sold on a non-recourse basis; however, representations and warranties have been made that are customary for loan sale transactions, including eligibility characteristics of the mortgage loans and underwriting responsibilities, in connection with the sales of these assets.
	In order to facilitate the origination and sale of mortgage loans held for sale, the Company entered into various agreements with warehouse lenders. Such agreements are in the form of loan participations and repurchase agreements with banks and other financial institutions. Mortgage loans held for sale are considered sold when the Company surrenders control over the financial assets and such financial assets are legally isolated from the Company in the event of bankruptcy. For loan participations and repurchase agreements that meet the sale criteria, the transferred financial assets are derecognized from the balance sheet and a gain or loss is recognized upon sale. If the sale criteria are not met, the transfer is recorded as a secured borrowing in which the assets remain on the balance sheet and the proceeds from the transaction are recognized as a liability. As of March 31, 2014 and 2013, all repurchase agreements are accounted for by the Company as secured borrowings.
	From time to time, the Company may sell loans whereby the underlying risks and cash flows of the mortgage loan have been transferred to a third party through the issuance of participating interests. The terms and conditions of these interests are governed by the participation agreements. In the instances where the loan participation has qualified for sale treatment, the Company will act as an agent on behalf of the participating entity when negotiating the terms of the ultimate sale of the underlying mortgage loans to FNMA, FHLMC or into pools of GNMA MBS. The Company will receive a marketing fee paid by the participating entity upon completion of the sale. In addition, the Company will also service the underlying mortgage loans to the participation agreement for the period that the participating interests are outstanding. As of March 31, 2014 and 2013, all participation arrangements were accounted for by the Company as secured borrowings.
	The following table sets forth information regarding cash flows for the three months ended March 31, 2014 and 2013 relating to loan sales in which the Company has continuing involvement:
		Three Months Ended March 31,
		2014			2013

	1 Represents the proceeds from mortgage loans or pools of mortgage loans sold to FNMA, FHLMC, and GNMA and is presented net of the related repayments of borrowings under the Company's mortgage funding arrangements used to fund the related mortgage loans prior to sale as well as the cost to retain the servicing rights.
	The following table sets forth information related to outstanding loans sold as of March 31, 2014 and December 31, 2013 for which the Company has continuing involvement:
		March 31, 2014			December 31, 2013

	Loans delinquent 90 or more days or in foreclosure 1	$	46,495		$	32,269
	1 Includes GNMA mortgage loans, which are government-insured, of $38,443 and $26,268, respectively, as of March 31, 2014 and December 31, 2013.
	The key assumptions (or range of assumptions) used in determining the fair value of the Company’s MSRs as of March 31, 2014 and December 31, 2013 are as follows:
		March 31, 2014			December 31, 2013
	Discount rates	9.25% - 11.00%			9.25% - 11.00%
	Annual prepayment speeds (by investor type):

	FNMA	8.4		%	7.8		%
	GNMA I	8.4		%	8.1		%
	GNMA II	7.9		%	7.6		%
	FHLMC	8.6		%	7.7		%
	Cost of servicing (per loan)	$	75		$	74
	1 Represents older, higher interest rate loans acquired from the Company's merger with Swain in 2009.
	The key assumptions (or range of assumptions) used in determining the fair value of the Company’s MSRs at initial recognition during the three months ended March 31, 2014 and 2013 are as follows:
		Three Months Ended March 31,
		2014		2013
	Discount rates	9.25% - 11.00%		9.25% - 11.00%
	Annual prepayment speeds (by investor type):
	FNMA	8.21% - 8.38%		9.27% - 9.67%
	GNMA I	8.37% - 8.55%		12.09% - 12.89%
	GNMA II	7.81% - 7.99%		8.89% - 9.27%
	FHLMC	8.28% - 8.58%		N/A
	Cost of servicing (per loan)	$74 - $75		$73 - $74
	MSRs are generally subject to loss in value when mortgage rates decrease. Decreasing mortgage rates normally encourage increased mortgage refinancing activity. Increased refinancing activity reduces the life of the loans underlying the MSRs, thereby reducing MSR value. Reductions in the value of MSRs affect income through changes in fair value. These factors have been considered in the estimated prepayment speed assumptions used to determine the fair value of the Company’s MSRs.
	In addition to the assumptions provided above, the Company uses assumptions for default rates in determining the fair value of MSRs. These assumptions are based primarily on internal estimates, and the Company also obtains third-party data, where applicable, to assess the reasonableness of its internal assumptions.  In the MSRs valuation as of March 31, 2014, the Company’s assumptions for default rates for FNMA, GNMA and FHLMC mortgage loans were 3.99%, 6.46% and 3.81%, respectively. In the MSRs valuation as of December 31, 2013, the Company's assumptions for default rates for FNMA, GNMA and FHLMC were 3.97%, 6.44%, and 3.82% respectively. The default rates represent the Company’s estimate of the loans that will eventually enter foreclosure proceedings over the entire term of the portfolio’s life.  These assumptions affect the future cost to service loans, future revenue earned from the portfolio, and future assumed foreclosure losses.  Because the Company’s portfolio is generally comprised of recent vintages, actual future defaults may differ from the Company’s assumptions.
	The hypothetical effect of an adverse change in these key assumptions would result in a decrease in the fair values of MSRs as follows as of March 31, 2014 and December 31, 2013:
		March 31, 2014			December 31, 2013
	Discount rates:
	Impact of discount rate + 1%	$	(9,483	)	$	(8,706	)
	Impact of discount rate + 2%	$	(18,144	)	$	(16,638	)
	Impact of discount rate + 3%	$	(26,079	)	$	(23,889	)
	Prepayment speeds:
	Impact of prepayment speed * 105%	$	(4,183	)	$	(3,558	)
	Impact of prepayment speed * 110%	$	(8,228	)	$	(7,003	)
	Impact of prepayment speed * 120%	$	(15,927	)	$	(13,570	)
	Cost of servicing:
	Impact of cost of servicing * 105%	$	(1,321	)	$	(1,157	)
	Impact of cost of servicing * 110%	$	(2,641	)	$	(2,314	)
	Impact of cost of servicing * 120%	$	(5,283	)	$	(4,629	)
	As the table demonstrates, the Company’s methodology for estimating the fair value of MSRs is highly sensitive to changes in assumptions. For example, actual prepayment experience may differ and any difference may have a material effect on MSR fair value. Changes in fair value resulting from changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, in this table, the effect of a variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumption; in reality, changes in one factor may be associated with changes in another (for example, decreases in market interest rates may indicate higher prepayments; however, this may be partially offset by lower prepayments due to other factors such as a borrower’s diminished opportunity to refinance), which may magnify or counteract the sensitivities. Thus, any measurement of MSR fair value is limited by the conditions existing and assumptions made as of a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time.

	The Company maintains mortgage participation, repurchase and warehouse lines of credit arrangements (collectively referred to as “mortgage funding arrangements”) with various financial institutions, primarily to fund the origination of mortgage loans which are subject to participation. As of March 31, 2014 the Company held mortgage funding arrangements with 3 separate financial institutions and a total maximum borrowing capacity of $1,151,000. Each mortgage funding arrangement is collateralized by the underlying mortgage loans.
	The following table summarizes the amounts outstanding, interest rates and maturity dates under the Company’s various mortgage funding arrangements as of March 31, 2014:

	The Company intends to renew the mortgage funding arrangements when they mature and has no reason to believe the Company will be unable to do so.
	On March 31, 2014, the Company amended its master participation agreement with Merchants Bank of Indiana ("Merchants") to increase the aggregate maximum borrowing capacity from $400,000 to $600,000 through May 31, 2014, with the aggregate maximum borrowing capacity reverting back to $400,000 on June 1, 2014 until the agreement matures on June 30, 2014.
	On March 31, 2014, the Company entered into two changes to its facilities with Merchants: a) it amended its mortgage warehouse and security agreement with Merchants to decrease the maximum borrowing capacity under the line of credit with Merchants from $2,000 to $1,000 and b) it amended its operating line of credit agreement with Merchants to increase the maximum borrowing capacity from $7,200 to $11,000 through May 31, 2014. The maximum borrowing capacity reverts back to $7,200 on June 1, 2014 until the operating line of credit agreement matures on June 30, 2014.
	On March 25, 2014, the Company amended its master repurchase agreement with Bank of America, N.A. ("Bank of America") to increase the aggregate outstanding purchase price under the agreement from $200,000 to $250,000 and extend the termination date to April 30, 2014. On April 30, 2014, the master repurchase agreement with Bank of America was amended further to extend the maturity date to May 31, 2014. On May 12, 2014, the master repurchase agreement with Bank of America was increased to $400,000 and renewed until its maturity date of May 11, 2015.

	Losses on repurchases and indemnifications	(351		)	(45		)
	Balance at end of period	$	4,231		$	2,871
	Because of the uncertainty in the various estimates underlying the mortgage repurchase and indemnifications liability, there is a range of losses in excess of the recorded reserve for mortgage repurchase and indemnifications that is reasonably possible. The estimate of the range of possible loss for representations and warranties does not represent a probable loss and is based on current available information, significant judgment and a number of assumptions that are subject to change. The high end of this range of reasonably possible losses in excess of the Company’s recorded reserve was approximately $2,315 at March 31, 2014, and was determined based upon modifying the assumptions (particularly to assume significant changes in investor repurchase demand practices) utilized in the Company’s best estimate of probable loss to reflect what it believes to be the high end of reasonably possible adverse assumptions.

	Commitments and Contingencies
	Commitments to Extend Credit
	The Company enters into interest rate lock commitments ("IRLCs") with customers who have applied for residential mortgage loans and meet certain credit and underwriting criteria. These commitments expose the Company to market risk if interest rates change and the loan is not economically hedged or committed to an investor. The Company is also exposed to credit loss if the loan is originated and not sold to an investor and the customer does not perform. The collateral upon extension of credit typically consists of a first deed of trust in the mortgagor’s residential property. Commitments to originate loans do not necessarily reflect future cash requirements as some commitments are expected to expire without being drawn upon. Total commitments to originate loans as of March 31, 2014 and December 31, 2013 approximated $1,489,053 and $1,190,119, respectively.
	Litigation
	The Company is subject to various legal proceedings arising out of the ordinary course of business. As of March 31, 2014, there were no current or pending claims against the Company, which could have a material impact on the Company's statement of financial position, net income or cash flows.
	Other Contingencies
	During 2013, the Company became aware that it had purchased certain refinancing loans, with a total principal amount of $5,163, from a correspondent lender where the prior mortgage loan on the property securing the mortgage loan that was purchased from the correspondent was not satisfied and released by the correspondent’s title company at the time the loan from the correspondent was made. As part of the Company’s process in purchasing a mortgage loan from a correspondent, it generally requires that a closing protection letter be issued by the title insurer in favor of the borrower. A closing protection letter was obtained with respect to each of these purchased loans. As a result, the Company believes the borrower is insured against any liens prior to ours that were not identified in connection with the issuance of that closing protection letter. The Company believes that its procedures, including conducting a post-purchase audit, were effective in identifying the failure by the correspondent to obtain a release of the prior mortgage loan and that the Company’s practice of obtaining closing protection letters is appropriate to protect it in these situations. The Company has notified the affected borrowers and the relevant insurance carriers, and it expects that the title insurance obtained in connection with the refinancings will result in the loan having a first priority status. However, there can be no assurances that the prior mortgages will be fully satisfied from the title insurance claims.

	Issuance of Warrants
	On March 29, 2013, in conjunction with a $10,000 term loan the Company entered into with a stockholder, the Company issued warrants to the stockholder for the right to purchase 277,777 shares of its common stock at a price of $18.00 per share. The warrants are exercisable at any time through May 15, 2018. Because the warrants met the criteria of a derivative financial instrument that is indexed to the Company's own stock, the warrants' allocable fair value of $1,522 was recorded as a component of "Additional paid in capital" and resulted in a debt discount in the same amount.
	Use of Capital and Common Stock Repurchases
	The Company paid total cash dividends of $0 and $19 to its convertible preferred stockholders during the three months ended March 31, 2014 and 2013, respectively (the Company had no preferred stockholders during the three months ended March 31, 2014). The Company does not expect to pay dividends on its common stock for the foreseeable future. The declaration of future dividends and the establishment of the per share amount, record dates and payment dates for any such future dividends are subject to the final determination of the Company’s Board of Directors and will be dependent upon future earnings, cash flows, financial requirements and other factors.
	Common stock repurchases are discretionary as the Company is under no obligation to repurchases shares. The Company may repurchase shares when it believes it is a prudent use of capital. There were no repurchases of common stock during the three months ended March 31, 2014 or 2013.

Merchants Bancorp in turn, agreed to form and fund a wholly-owned subsidiary named NattyMac Funding Inc. (“NMF”) that will invest in participation interests in warehouse lines of credit ("WLOCs")originated by the Company's wholly-owned subsidiary, NattyMac, and in participation interests in residential mortgage loans originated by Stonegate. The amount of the subordinate debt funded by the Company will be sized to be greater than or equal to 10% of the assets of NMF. The subordinate debt provided to Merchants Bancorp will earn a return equal to one-month LIBOR, plus 350 basis points, plus additional interest that will be equal to 49% of the earnings of NMF.

	The accompanying unaudited consolidated financial statements include the accounts of Stonegate and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The Company has omitted certain financial disclosures that would substantially duplicate the disclosures in its audited consolidated financial statements as of and for the year ended December 31, 2013, unless the information contained in those disclosures materially changed or is required by GAAP. In the opinion of management, all adjustments, including normal recurring adjustments, necessary for a fair statement of the consolidated financial statements as of and for the three months ended March 31, 2014 and 2013 have been recorded. All intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2014. These unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2013 included in its 2013 Annual Report on Form 10-K.
Credit Risk	'
	In the normal course of business, companies in the mortgage banking industry encounter certain economic and regulatory risks. Economic risks include interest rate risk and credit risk. The Company is subject to interest rate risk to the extent that in a rising interest rate environment, the Company may experience a decrease in loan production, as well as decreases in the value of mortgage loans held for sale and in commitments to originate loans, which may negatively impact the Company’s operations. Conversely, in a decreasing interest rate environment, the value of the Company’s mortgage servicing rights ("MSRs") may decrease, which could negatively impact the Company’s operations. Credit risk is the risk of default that may result from the borrowers’ inability or unwillingness to make contractually required payments during the period in which loans are being held for sale.
Fair Value Measurements	'
	Fair Value Measurements
	The Company uses fair value measurements in fair value disclosures and to record certain assets and liabilities at fair value on a recurring basis, such as MSRs, derivatives and loans held for sale, or on a nonrecurring basis, such as when measuring intangible assets and long-lived assets. The Company has elected fair value accounting for loans held for sale to more closely align the Company’s accounting with its interest rate risk strategies without having to apply the operational complexities of hedge accounting.
	The Company groups its assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
	Level Input:	Input Definition:
	Level 1	Unadjusted, quoted prices in active markets for identical assets or liabilities.
	Level 2	Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing an asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets and liabilities, interest rates, prepayment speeds, credit risk and others.
	Level 3	Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity), unobservable inputs may be used. Unobservable inputs reflect the Company's own assumptions about the factors that market participants would use in pricing the asset or liability, and are based on the best information available in the circumstances.
	An asset 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.
	While the Company believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methods or assumptions to estimate the fair value of certain financial statement items could result in a different estimate of fair value at the reporting date. Those estimated values may differ significantly from the values that would have been used had a readily available market for such items existed, or had such items been liquidated, and those differences could be material to the consolidated financial statements.
	Management incorporates lack of liquidity into its fair value estimates based on the type of asset or liability measured and the valuation method used. The Company uses discounted cash flow techniques to estimate fair value. These techniques incorporate forecasting of expected cash flows discounted at appropriate market discount rates that are intended to reflect the lack of liquidity in the market.
	The following describes the methods used in estimating the fair values of certain financial statement items:
	Mortgage Loans Held for Sale: The Company's mortgage loans held for sale at fair value are saleable into the secondary mortgage markets and their fair values are estimated using quoted market or contracted prices or market price equivalents.
	Derivative Financial Instruments: The Company estimates the fair value of interest rate lock commitments based on the value of the underlying mortgage loan, quoted MBS prices and estimates of the fair value of the MSRs and the probability that the mortgage loan will fund within the terms of the interest rate lock commitment. The Company estimates the fair value of forward sales commitments based on quoted MBS prices.
	Mortgage Servicing Rights: The Company uses a discounted cash flow approach to estimate the fair value of MSRs. This approach consists of projecting servicing cash flows discounted at a rate that management believes market participants would use in their determinations of value. The key assumptions used in the estimation of the fair value of MSRs include prepayment speeds, discount rates, default rates, cost to service, contractual servicing fees and escrow earnings.
